Abstract. Theoretical and empirical studies investigating the relationship between the ex-
change rate and FDI have generated mixed results. Using bilateral Canadian-U.S. industry
level count data on cross-border mergers and acquisitions (M&As) and conditioning on
industry tariff rates, value added share of industries, industry M&A trend activity, and
the number of establishments, we find evidence that a real dollar depreciation of the home
currency leads to an increase in the probability of foreign M&As but only in high R&D
industries. These empirical results are consistent with Blonigen’s asset acquisition hypoth-
esis. Results on European M&As of Canadian firms also lean towards this result. JEL

Fusions et acquisitions trans-frontalières: est-ce que le taux de change a de l’importance?
Quelques résultats pour le Canada. Les études théoriques et empiriques de la relation
entre taux de change et investissement direct à l’étranger donnent des résultats mixtes. A
l’aide de données bilatérales canado-américaines au niveau de l’industrie, pour les fusions
et acquisitions (F&A) transfrontalières, et de certaines conditions imposées aux tarifs
douaniers au niveau industriel, à la part de la valeur ajoutée des industries, à la tendance des
F&A au niveau industriel, et au nombre des établissements, on montre qu’une dépréciation
de la devise nationale en termes de dollars réels entraı̂ne un accroissement de la probabilité
de F&A étrangères mais seulement dans les industries à forte intensité de R&D. Ces
résultats empiriques sont compatibles avec l’hypothèse d’acquisition d’actifs de Blonigen.
Les résultats quant aux F&A européennes de firmes canadiennes tendent à supporter ce
résultat.

1. Introduction

The decline in the value of the Canadian dollar relative to the U.S. dollar over
the late 1980s and 1990s raised concerns that Canadian firms were vulnerable
for takeover by U.S. firms at ‘fire sale’ prices. Descriptive data on the number
of U.S. mergers and acquisitions (hereafter M&As) in Canada lend support to
this claim. While the value of the Canadian dollar declined over 1994–2000, the
number of U.S. M&As increased from 168 in 1994 to 300 in 2000, with associated
real transaction values of CDN $5.3 billion and CDN $24.1 billion, respectively
(Investment Review, Statistics Canada).
   Theories on a link between exchange rates and cross-border M&As provide
ambiguous predictions. One view is that there is no link. While a Canadian dol-
lar depreciation relative to the U.S. dollar reduces the cost for U.S. firms of
acquiring Canadian assets, the revenues from these assets operating in Canada
are denominated in Canadian dollars. Upon repatriating the revenues, conver-
sion into U.S. dollars at the lower rate of exchange of U.S. dollars for Canadian
dollars offsets the cost reduction of the purchase. Thus there is no net impact of
a Canadian dollar depreciation on cross-border takeovers. This view treats the
asset as financial in nature, whereby costs and revenues are generated in only one
currency.
   A second view identifies the asset as a factor input that is transferable, such
as technology, whereby it can generate revenues in another currency. Blonigen
(1997) proposes such a theory, where the target firm has an innovation or a firm
specific asset. This ‘asset acquisition’ theory relies on the assumption of market
segmentation or imperfect markets for goods. Blonigen applied this theory to
the case of Japanese M&As of U.S. firms, partly motivated by the fact that the
Japanese market was relatively insulated from foreign penetration. The level of
imports from the U.S. and the number of U.S. multinationals in Japan over the
1980s were relatively low. Blonigen’s assumption of market segmentation would
thus well apply to the U.S.-Japan case.
   This paper tests Blonigen’s asset acquisition hypothesis by assessing the em-
pirical connection between the exchange rate and cross-border M&As, focusing
on Canadian inward and outward M&A data. No other similar study has used
Canadian data. In using Canadian data, this study will look at whether Blonigen’s
theory holds generally, or holds exclusively only in the case of pronounced mar-
ket segmentation, as in the U.S.-Japan case. While in the U.S.-Japan case market,
imperfect markets were mainly in the form of import restrictions and restrictions
on foreign multinational presence, there are other forms of market segmentation
such as established distributional or marketing networks in the acquiring firm’s
country or agglomeration advantages that the acquiring firm has in its country.
These other forms of market segmentation yield greater profitable opportunities
for the acquiring firm in its country relative to a foreign firm. Any such form of
market segmentation will produce the Blonigen effect. We thus test whether the
Blonigen result holds more broadly by using Canadian M&A data. Furthermore,

whereas Blonigen uses Japanese M&As in the U.S., this study looks at bilateral
Canada-U.S. M&A data, along with European M&As in Canada in testing the
asset acquisition hypothesis.
   Random and fixed-effects negative binomial approaches are employed to
model Canada-U.S. bilateral M&A count data. Explanatory variables include
the industry-specific real exchange rate, along with traditional determinants of
M&As. To further lend support to the acquisition hypothesis, we also look at the
role of the exchange rate on European M&As of Canadian firms. As a robustness
check, we investigate whether the exchange rate has a similar role on greenfield
investments.
   The following results emerge. There is support for Blonigen’s asset acquisition
hypothesis, as results from Canadian-U.S. bilateral data show that a home country
currency deprecation will increase the probability of a foreign M&A only in
high R&D intensity industries. Results from greenfield investments show that
the exchange rate does not play a role for high R&D industries.
   The organization of the paper is as follows. Section 2 reviews the literature
on the theoretical link between exchange rates and foreign direct investment
(hereafter FDI). Section 3 presents data trends on Canadian and U.S. M&A and
greenfield counts. Section 4 outlines the econometric methodology and presents
the determinants of cross-border M&As and the data used. Section 5 provides
the empirical results. Section 6 concludes.

2. Exchange rate - FDI link and related literature

Motives for FDI are organized around a framework that outlines the advantages
and conditions under which FDI will occur in light of the inherent disadvantages
and higher costs of foreign production. Early conceptualization of this framework
includes Dunning’s development of the ownership-location-internationalization
(OLI) framework (1988, 2001). Models that formalize these motives include
Markusen (1984; developing a horizontal model of FDI) and Helpman (1984;
model of vertical FDI). Markusen, Venables, and Zhang (1996) and Markusen
(1997) developed a ‘knowledge-capital’ model, which provides a framework that
integrates vertical and horizontal motives for FDI; Carr, Markusen, and Maskus
(2001) provide the first empirical investigation of the predictions from this model.
The models mentioned above attempt the difficult task of deriving general equi-
librium models of FDI behaviour. 1
    In this paper we employ a partial equilibrium framework in empirically mod-
elling FDI, focusing on the role of the exchange rate. Furthermore we focus on
one form of FDI, that being cross-border M&As. Cross-border M&As offer two
main advantages over start-up or greenfield investments. One advantage is greater
speed in gaining market presence. A second advantage is access to proprietary as-
sets. The target firm may have an asset that is not tangible or licensable, such as a

 1 See Blonigen, Davies and Head (2003) on issues concerning the empirical model of Carr et al.
   (2001).
Cross-border mergers and acquisitions     453

scientific technology, a management or organizational skill and/or marketing ex-
pertise. This asset acquisition motivation underlies the exchange rate cross-border
M&A link.
   Explanations for exchange rate effects on FDI typically divide into two cate-
gories, relative wage effects (Caves 1989) and relative wealth effects (asymmetric
information in capital markets: Froot and Stein 1989; stock market performances:
Klein and Rosengreen 1994 and Dewenter 1995). Both sets of theories predict
that a currency depreciation will lead to increased inward FDI.
   A shortcoming of the relative wage and wealth explanations is their inherent
assumption that only the price of the asset matters in locating abroad, whereas the
relevant factor is the rate of return. Blonigen (1997) overcomes this issue, provid-
ing both theoretical and empirical evidence in support of an inverse relationship
between a domestic country’s currency value and the amount of foreign acquisi-
tions of domestic firms. His theory assumes that FDI is motivated by acquiring
firm-specific assets that are transferable. Blonigen’s theory relies on the assump-
tion of imperfect goods markets, where the domestic firm has limited access to
the foreign market to sell its product. For example, suppose a U.S. firm and a
Canadian firm have equal opportunity to purchase a Canadian firm possessing a
transferable technology. A depreciation of the Canadian dollar will increase the
present discounted profits of the U.S. firm as the cost of acquiring the Canadian
firm decreases. The present discounted value of profits for the Canadian acquir-
ing firm does not change or changes marginally because it has no or limited
access to the U.S. market as a result of imperfect goods markets. This may be due
to superior or established networks of the U.S. firm in the U.S. in the form of
buyer and seller relationships and distributional networks (Greaney 2003; Rauch
and Watson 2005; Helliwell 2002; Head, Ries, and Spencer 2002). It may also be
that only the U.S. firm is part of a cluster or an agglomeration, where the U.S.
firm’s potential profitability from the acquired Canadian firm is higher, owing
to knowledge spillovers from localized related industries and research centres. In
general, a U.S. firm is more familiar with the workings of the U.S. market relative
to a Canadian firm and will have more profitable opportunities. Therefore, the
potential Canadian target firm will be more valuable to the U.S. firm than to
the Canadian firm following a Canadian dollar depreciation. Using count data
on the number of Japanese M&As of U.S. firms over 1975–92, Blonigen finds
that a U.S. dollar depreciation increases the likelihood of Japanese M&As in U.S.
industries, particularly in those that are R&D intensive.
   The acquisition hypothesis presumes that the technology is transferred to the
U.S. after the Canadian firm is acquired. This seems intuitive and is supported by
McFetridge (1987), Caves (1996), and Van Pottelsberghe and Lichtenberg (2001)
who show that technology is quickly transferred back to the parent company’s
market.
   The literature concerning Canadian studies is sparse. Schembri (2002) and
Aba and Mintz (2002) plot the net annual value of acquisition flows (value of
foreign acquisitions of Canadian assets less value of Canadian acquisition of
foreign assets) over 1975–2000. The data show no overwhelming evidence of a
454    G.J. Georgopoulos

positive trend over the 1990s. Neither study, however, investigates the role of the
Canada-U.S. exchange rate to U.S. cross-border M&As while conditioning on
other determinants; that is, neither employs a formal econometric model. 2
   Lafrance and Tessier (2001) employ Vector Autoregression (VAR) analysis,
where the VAR contains Canadian inward FDI flows, the real exchange rate, and
a measure of exchange rate volatility. Using the sample period 1970:1-2000:1,
they find that the level of the real exchange rate Granger causes inward FDI,
although the result was not robust to the introduction of the ratio of undistributed
corporate profits to GNP. A shortcoming of the Granger technique is that it does
not provide an estimate of the direction or magnitude of the exchange rate-FDI
relationship. Furthermore their paper does not distinguish between M&A and
greenfield investments.
   An extensive study on the role of the exchange rate on cross-border M&As in
involving Canada has not been done. This paper fills this void. Using bilateral
count data on the number of cross-border M&As between Canada and the U.S.,
along with European M&As of Canadian firms, Blonigen’s asset acquisition
hypothesis is tested. Robustness checks are also conducted by looking at the role
of the exchange rate on greenfield acquisitions.

3. Merger and acquisition trends in Canada

According to the World Investment Report (UNCTAD 2000), cross-border
M&As were the major driving force in the substantial increase in FDI over the
late 1990s. During the span of 1999, cross-border M&As increased by 3%, rep-
resenting over one-third of total FDI for that year. Of all M&A transactions,
approximately 3% were in the form of mergers and 97% were in the form of ac-
quisitions. Among developed countries, approximately 85% of total FDI is in the
form of cross-border M&As.
   Table 1 presents bilateral data of U.S. and Canadian FDI, by M&As and
greenfield investments, where it shows FDI data in all industries, high R&D
manufacturing and low R&D manufacturing. 3 A few patterns emerge from the
data. First, there are considerably more M&A investments than greenfield invest-
ments by both countries. Second, acquisitions fluctuate more from year to year
than the start-up of new establishments. Third, there are more transactions in low

 2 Moreover, Aba and Mintz (2002) do not consider the possibility that Canadian acquisitions of
   foreign firms may have resulted from a Canadian dollar appreciation relative to the associated
   countries. For example, the Canadian dollar generally appreciated relative to the English Pound,
   the German Mark and the French Franc and Japanese Yen over the latter part of the 1990s, thus
   potentially explaining Canadian M&As in these countries. Also, in using values of transactions,
   this may lead to one or two large value transactions dominating the total value of transactions,
   which would then misrepresent net M&A activity between the two countries. This issue is
   avoided when looking at the number of transactions (count data).
 3 In this study all data on M&As and greenfields exclude governmental service industries. High
   and Low R&D manufacturing groupings are defined in Section 5.
Cross-border mergers and acquisitions   455

 R&D manufacturing industries than high R&D industries, partly because there
are more industries in the former group. This analysis will determine whether the
exchange rate has differential effects between these two groups.
   The table also shows that the Canadian dollar depreciated significantly from
1991 to 1992 and continued to do so over the latter part of the 1990s up to 2001.
The data roughly suggest an association between the value of the Canadian dol-
lar and the number of U.S. M&As, as the number of M&As generally increased
over the periods of depreciations. U.S. greenfield investments seem less respon-
sive, generally showing a slight decline over the 1990s relative to the 1980s. This
indicates possible differential responses of M&As and greenfields to exchange
rate changes. Both forms of Canadian FDI seem more stable relative to the U.S.
numbers, although Canadian greenfields have declined noticeably since the late
1990s.
   Table 2 reports the top 30 Canadian industries experiencing the highest num-
ber of U.S. M&As. The wholesale petroleum products sector experienced the
most M&A activity, where 185 transactions took place over 1985–2001. The
data show that a fair amount of M&A activity occurred in the wholesale indus-
try, which consists of SIC codes 5011–5999. Of the 30 reported codes, 11 are in
the wholesale industry. Of the top 13 sectors, 6 are in wholesale. The high fre-
quency of M&As in the wholesale industry may partially be explained by the
high number of establishments in each SIC code. The last two columns in table 2
show that for most of the wholesale industries there were more than 2,000 es-
tablishments in 2001, the industry average for that year being 1,204 (bottom of
table 2).
   Looking more closely at the data in table 2, we see that the number of estab-
lishments is not the only factor driving the frequency of M&As. There were 67
M&A transactions in industries with codes 3192 and 7512, yet the number of
establishments in each differed substantially. The same can be said of industries
in codes 7771 and 3799, which experienced 51 and 46 M&As, respectively. Thus,
there are other determinants of cross-border M&As beyond the number of es-
tablishments. The exchange rate may be one such determinant, along with other
factors.
   In an overview of Canada-U.S. bilateral M&A activity in all industries, fig-
ures 1 and 2 present the distribution of the number of M&As by major industry
groupings over the sample periods. For U.S. M&As over 1985–2001 there were
a total of 4,376, predominantly in the manufacturing and wholesale and retail
trade industries. Most of the Canadian M&As were in manufacturing, with a
substantially smaller proportion of M&As of firms in the wholesale industry
relative to U.S. M&As of Canadian firms.
   The data from tables 1 and 2 suggests that the exchange rate may be a de-
terminant of M&As, along with other determinants such as the number of es-
tablishments and perhaps M&A trend activity. These and other factors will be
investigated in the empirical model.

4. Empirical model and data

The random effects negative binomial (hereafter RENegbin) model proposed by
Hausman, Hall, and Griliches (1984) is employed to model the determinants
of the number of cross-border M&As. As opposed to the Poisson model, the
RENegbin model allows for the conditional expected value and the variance
of the number of M&As to differ, that is, allowing for overdispersion. Given
the panel nature of the data used here, the RENegbin model allows dispersion
to vary randomly across industries. Hausman tests are presented to determine
whether the fixed effects negative binomial model is more appropriate than the
random effects model. 4 Appendix 1 discusses the RENegbin model in more
detail.
    We begin with U.S. M&As of Canadian firms. The dependent variable is the
number of U.S. M&As of Canadian firms at the 4-digit SIC level, excluding
government services industries. There are 400 balanced panels of industry clas-
sifications. 5 See appendix B for details about the collection of these and other
data.
 4 Hausman, et al. (1984) state that the RENegbin model yields asymptotically more efficient
   estimators than their fixed effects model. For these results to be consistent, the industry-specific
   effects need to be uncorrelated with the regressors.
 5 The number of panels used was constrained by the fixed effects estimation methodology. This
   methodology removes the fixed effects by conditioning on the number of positive outcomes
   within each panel. Therefore if all the outcomes for the dependent variable are zero (or all
   outcomes of the dependent variable are the same) for a particular panel, then that panel does
   not contribute to the likelihood function and it is dropped from the sample set. For direct
Cross-border mergers and acquisitions              459

    The regressors chosen generally follow Blonigen (1997). The industry-specific
real exchange rate is constructed using the nominal Canadian dollars per U.S.
dollar exchange rate, and 2-digit SIC price indexes for the U.S. and Canada.
Concordance tables from Statistics Canada were used to match Canadian 1980
SIC codes with U.S. 1987 SIC codes. An increase in the industry-specific real
exchange rate reflects a real Canadian dollar depreciation. According to the asset
acquisition hypothesis, such a depreciation should be positively correlated with
the dependent variable.
    Cross-border M&As may result from foreign firms avoiding tariffs and other
restrictions that nations impose on imports. Thus, cross-border M&As are alter-
native strategies to penetrate a domestic market. This strategy effect is captured
by including effective Canadian tariff rates on imports from the U.S. at the 4-digit
SIC level. A positive correlation between this variable and the dependent variable
is expected.
    To account for factors affecting U.S. demand for Canadian firms, the growth
rate of U.S. real GDP and the share of value added output to total GDP
of U.S. industry i at the 2-digit SIC level were employed. Concordance ta-
bles were used for the latter variable. These demand factors may reflect hor-
izontal mergers as firms seek to achieve greater market presence and power.
The demand variables should positively affect the number of U.S. M&As in
Canada.
    For supply variables, as is illustrated in table 2, the larger the sector size mea-
sured by the number of establishments, the higher the probability of a U.S. ac-
quisition, ceteris paribus. Thus, we include the total number of Canadian es-
tablishments at the 4-digit SIC level. To capture the overall climate of M&A
activity in Canada, the number of M&As of Canadian firms by Canadian firms
at the 4-digit SIC level is included. A positive climate of M&A opportunities
in Canada should be reflected by a high amount of M&As by Canadian firms.
A positive climate should also increase the probability of an acquisition by a
U.S. firm. Thus, there should be a positive correlation between the number of
Canadian M&As and U.S. M&As. This supply variable should be positively cor-
related with the dependent variable. 6 Finally, to capture wealth effects from the
stock market, we include Morgan Stanley’s growth in market capitalization for
the U.S.

   comparison, we use the same fixed effects sample set as for the random effects estimation.
   Although not reported here, the random effects results from the unrestricted (larger) sample set
   are similar to the random effects results from the restricted sample set reported in Tables 3-5; the
   results are robust. The results from the unrestricted random effects model are available upon
   request.
 6 As does this paper, Blonigen (1997) uses a similar real exchange rate, along with the two demand
   variables and the number of domestic M&As. A notable difference is that Blonigen’s acquisition
   data are at the 3 digit level, whereas the U.S. acquisition of Canadian firms used in this study are
   at the 4 digit level.

  Thus, the following is the testing specification in the context of U.S. M&As of
Canadian firms:

   Prob(USM&Asit ) = f (rerit , tariff it , USgrowtht , USsharei t ,
                              CDNM&Asit , CDNestabit , USMCgrowtht ),                             (1)

where USM&As it is the number of U.S. M&As in Canada at the 4-digit Canada
SIC level; rer it is the Canada-U.S. real exchange rate at the 2-digit SIC level;
tariff it is the effective tariff rate on imports from the U.S. at the 4-digit SIC
level; USgrowth t is the growth rate of U.S. real GDP; USshare it is share of value
added of U.S. industry i at the 2-digit SIC level; CDNM&As it is the number of
Canadian M&As at the 4-digit SIC level; CDNestab it is the number of Canadian
establishment at the 4-digit SIC level; and USMCgrowth t is the growth in market
capitalization in the U.S. The data reflect the highest available level of disaggre-
gation. The data are at annual frequency (t) and cover the period 1985–2001.

5. Empirical results

5.1. U.S. M&As of Canadian firms
Table 3 presents estimation results involving U.S. M&As of Canadian firms.
Columns 1 and 2 show the random- and fixed-effects estimates from the sample
of all industries. To determine whether the industry-specific effects are correlated
with the regressors, the Hausman (1978) test statistic is reported at the bottom of
column 1, which tests the specification of the random effects model in column 1
and the fixed effects model in column 2. This test is distributed as χ 2 under the
null hypothesis of no correlation between the industry-specific effects and the
regressors. The p-value, reported in brackets, is 0.090, suggesting the random ef-
fects is appropriate at the 5% level of significance. The results in column 1 thus are
appropriate, although the fixed-effects results are relatively similar. The bottom
of column 1 also reports a likelihood ratio test which compares the RENegbin
or panel estimator with the Negbin model or pooled estimator. The test statistic
rejects the null hypothesis of the pooled estimator or the Negbin estimator with
constant dispersion. 7
    The random-effects results in column 1 show that all the coefficients have
expected signs. Focusing on the real exchange rate reveals that the sign is what
is expected, suggesting that a rise in the real exchange rate – a real depreciation

 7 Although not reported, the likelihood ratio test on the alpha parameter is used to determine
   whether the data can be modeled by a Poisson process. A value of zero for the alpha parameter
   implies that the observations are generated by a Poisson process, or no overdispersion, which is a
   special case of the Negbin model. For this and all specifications, the Poisson model is rejected in
   favour of the Negbin model. The test results and estimates of the alpha parameter are available
   upon request.

of the Canadian dollar – will increase U.S. M&As in Canada. However, the real
exchange rate is statistically insignificant. This result appeals to the view that
there is no link between the exchange rate and FDI; the depreciation of the
domestic currency will leave the rate of return of a foreign investor equal to that
of a domestic investor, as the profits are repatriated at a higher exchange rate. The
tariff rate, the U.S. real GDP growth, and the number of establishments in each
sector are significant at the 5% level, while the U.S. industry share and the market
capitalization growth rate of the U.S. stock market are statistically significant at
the 10% level. Overall, for the full sample, the traditional determinants of FDI
perform well in this empirical specification.
   To test the asset acquisition hypothesis, along the lines of Blonigen (1997) we
focus on acquisitions in manufacturing as firm-specific assets would be important
462   G.J. Georgopoulos

for this industry. We examine whether manufacturing firms with high R&D in-
tensities are more likely to be acquired after a domestic currency depreciation
relative to low R&D intensity firms. High R&D industries are more likely to
have technology-related firm-specific assets. According to the asset acquisition
hypothesis proposed by Blonigen (1997) these industries are expected to ex-
perience a higher number of cross-border M&A activity in the presence of a
domestic currency depreciation, as domestic firm-specific assets that are trans-
ferable become less costly to acquire. We split manufacturing into high R&D
industries and low R&D industries, where high R&D industries are classified
as those having ratios of R&D expenditures to sales above the manufactur-
ing average. The industries with ratios consistently greater than the average
are reported at the bottom of table 3. Most are the traditional R&D indus-
tries such as machinery, electrical products, and pharmaceutical and medicine
industries. 8
   Columns 3 and 4 present the results from high R&D manufacturing. At the
bottom of column 3 the Hausman test shows that the fixed-effects model is the
correct empirical model, although again the random effects results are similar.
In column 4, of importance is that the real exchange rate is now statistically
significant. Furthermore, the value of the coefficient is considerably larger than
in column 1. These results lend support to Blonigen’s (1997) asset acquisition
hypothesis.
   In addition the tariff rate went from being significant in the full sample case
to insignificant. This result is intuitively appealing, as a tariff barrier is not a
primary factor for a foreign firm whose primary motive is to acquire transferable
assets. Industry share is still significant and has the expected sign, along with the
number of establishments.
   Columns 5 and 6 show the results from the low R&D manufacturing industries.
The Hausman test accepts the null hypothesis of no correlation between industry
specific effects and the regressors. Thus, in column 5, of importance is that the real
exchange rate is now statistically insignificant. For those firms having a relatively
low level of technology intensities, there is little if any M&A activity in their
associated industries for the purpose of asset acquisition; thus, the exchange rate
does not matter. Note that the tariff rate is now significant. With respect to these
industries, the suggested motive for cross-border M&As is to gain access to a
new market or exploit economies of scale, where this mode of entry substitutes
for trade in the presence of tariffs. Industry share is not significant, whereas the
remaining variables have expected signs and are statistically significant. These
results also hold for the fixed-effects estimates.
   The results show that the exchange rate is a statistically significant factor only
for cross-border M&As of firms with high R&D intensities. Tariff rates are not

statistically significant for high R&D firms. This is expected when the primary
motive for an M&A is to acquire a firm-specific asset that is transferable. The
exchange rate does not play a role for cross-border M&As for industries with low
levels of R&D intensity, whereas tariff rates do.

5.2. Canadian M&As of U.S. firms
Further evidence that would support the asset acquisition hypothesis would be to
find a reduction in the probability of Canadian M&As of U.S. high R&D firms
after a Canadian dollar real depreciation. We investigate this using count data
on the number of Canadian M&As of U.S. firms. These data were provided by
the Bureau of Economic Analysis, where it was available only at the 3-digit U.S.
SIC level beginning in 1987.
    Table 4 presents the results, where again similar explanatory variables were
used but in the context of determinants of Canadian M&As of U.S. firms. For data
sources on these variables see appendix B. For the full sample case, the Hausman
test shows that the fixed-effects estimation results in column 2 are appropriate.
The estimated coefficient on the real exchange rate is statistically significant, but
has an unexpected sign, although the coefficient is relatively small in magnitude.
The growth rate of Canadian real GDP is statistically significant and positively
affects the probability of a Canadian M&A in the U.S. A questionable result
is the statistically significant negative effect of the market capitalization rate in
Canada.
    The estimation was again taken for the high and low R&D manufacturing
industries, where R&D shares were provided by the U.S. National Science Foun-
dation. The high R&D U.S. industries are reported at the bottom of table 4.
    For high R&D firms, the fixed effect results of column 4 show evidence sup-
porting the asset acquisition hypothesis. Specifically, the real exchange rate now
has a negative affect, which is consistent with the asset acquisition theory; a
real depreciation of the Canadian dollar decreases the probability of a Canadian
firm acquiring a U.S. firm, although this effect is statistically significant at the
10% level. The random-effects model provides similar evidence, where the real
exchange rate is significant at the 1% level. U.S. domestic M&A activity has a
positive effect and is significant at the 10% level. The result on tariffs is unclear,
as the coefficient is negative and significant.
    For low R&D industries, the exchange rate results from the random effects
model differ from the high R&D in that the sign has changed and is statistically
insignificant, further supporting the asset acquisition hypothesis. U.S. domestic
M&A activity and the number of establishments in an industry are the main
factors driving Canadian M&As of low R&D U.S. firms.
    The results from tables 3 and 4 show support of the asset acquisition effect
holding bilaterally. Given a Canadian dollar depreciation, the probability of U.S.
M&As of Canadian high R&D firms increases, while the probability of Canadian
M&As of U.S. high R&D firms decreases.

5.3. European M&As of Canadian firms
The asset acquisition hypothesis should apply to other countries’ M&A activities
in Canada. We look for further support by investigating total M&As of Canadian
firms by the U.K., France, and Germany (Euro3 henceforth) as a whole. 9 They
account for a total of 67% of total non-U.S. foreign M&As of Canadian firms.

 9 Comparable data on Canadian M&As in these 3 European countries and the determinants are
   not available.

Owing to the relative infrequency of M&As for each of these countries separately
across all 4-digit SIC categories, we used the total amount of M&As from these
three countries as the dependent variable. 10 Figure 3 shows the distribution of
Euro3 M&As of Canadian firms over 1985–2001. The majority of M&As were
in manufacturing and wholesale and retail trade industries.
   Table 5 shows regressions similar to those used in table 3, but in the context of
Euro3 determinants of M&As in Canada. The acquisition data again were taken
from the Investment Review, Statistics Canada, and are at the 4-digit SIC level.
The real exchange rate measure is the simple unweighted average of the three
Canada-country-specific real exchange rates, where the individual real exchange
rates were positively correlated. 11 Data sources of the remaining variables are
outlined in appendix B.
   We again estimate over all industries and over high and low R&D manu-
facturing industries. Over all industries, the random effects model shows that
the average real exchange rate has a negative sign and is statistically signifi-
cant. Real GDP growth of the three European countries, industry share, and
the number of Canadian establishments are positive and statistically signif-
icant. Tariff rates and the number Canadian domestic acquisitions are in-
significant, whereas the average stock market capitalization growth is signif-
icant but has a negative sign. The interpretation of the latter effect is not
clear.
   For high R&D manufacturing industries, the fixed-effects model shows that
the real exchange rate effect is insignificant, but of interest is that the coefficient
is now positive, a sign consistent with the asset acquisition hypothesis. 12 The

10 The U.S. accounts for 72% of foreign M&As in Canada from 1985-2001, with the remaining
   countries accounting for 28%. The total number of M&As by France, Germany, and the U.K.
   over this period were 279, 200, and 810 respectively.
11 The correlation between the Canadian-German and Canadian- French real exchange rates was

insignificant coefficient may reflect more disparate or heterogeneous firms and
production processes between Canada and Europe relative to Canada and the
U.S., thus leading to fewer opportunities for accessing complimentary assets. For
low R&D industries, the average real exchange rate is insignificant. Of note is
that its magnitude is nearly half the size of the high R&D coefficient.
   Overall, while the real exchange rate is insignificant in the high R&D case, the
effect becomes positive relative to the full sample case and is noticeably larger than
the low R&D effect, evidence leaning towards the asset acquisition hypothesis.
   From the three cases above, in the Canada-U.S. bilateral case there is support
for the asset acquisition hypothesis, where the European case leans towards this

   having an expected sign but being statistically insignificant.

hypothesis. For M&As in low R&D manufacturing industries the exchange rate
does not play a role.

5.4. Greenfield investments
Access to proprietary assets certainly is not relevant when investigating the fac-
tors for greenfield investments. We would thus not expect the exchange rate to
play a role in this form of FDI. We next look at the role of the exchange rate on
U.S. greenfield investments in Canada, Canadian greenfield investments in the
U.S., and Euro3 greenfield investments in Canada. Figures 4–6 show the distribu-
tion of each, respectively, by major industry groupings. All three source countries
show a significantly lower proportion of greenfield investment in manufacturing
relative to M&A investment in manufacturing. For U.S. and Euro3 greenfield
investment in Canada, the dominant proportion is in the wholesale and retail in-
dustries, whereas for Canadian greenfield investments in the U.S., the proportion
of finance, insurance, and real estate dominates.
   We run specifications similar to those used in equation (1) for greenfield in-
vestments, but excluding the number of domestic acquisitions, as there is no
theoretical evidence suggesting that this variable affects greenfield investments.
In table 6 we report for all countries only the results from the key variables of
interest, the exchange rate, and the tariff rate. 13 For the Canada-U.S. bilateral

case (results (a) and (b)), the exchange rate does not play a role in determining
inward greenfield investments. Of note is that the exchange rate is not signifi-
cant in the high R&D manufacturing case, a result unlike the M&A case of high
R&D manufacturing industries. Overall, tariffs play a greater role in determining
greenfields relative to the M&A results of tables 3–5, reflecting the conventional
result of foreign firms jumping tariffs through greenfield investments to access

markets. Furthermore in the case of Canadian greenfields in the U.S., the tariff
rate now has the expected sign unlike the situation in the M&A case.
    For the European results, the exchange rate coefficient in the high R&D case
is negative and insignificant. The exchange rate results in the full sample and low
R&D sample cases are mixed. The tariff rate for all three samples have unexpected
signs, with the results for manufacturing industries being insignificant.
    Overall, there is no role for the exchange rate in determining greenfield invest-
ments in high R&D industries, a result different from the Canada-U.S. bilateral
M&As in high R&D industries. In general, the role for the exchange rate for
greenfields is weak.

6. Concluding remarks

While most previous studies on the effect of the exchange rate on FDI have
produced ambiguous results, this study contributes to the understanding of this
relationship by focusing on one form of FDI: mergers and acquisitions. Using
U.S. and Canadian bilateral M&A data, the results showed that a real currency
depreciation leads to an increase in the probability of a cross-border M&As
but only in high R&D intensive industries, and evidence on European M&As
of Canadian firms lean towards this result. These results are consistent with
Blonigen’s asset acquisition hypothesis; however, this is the first study using
Canadian data on cross-border M&As. The results lend support to the asset
acquisition holding more generally or beyond the U.S.-Japan setting, where the
degree of market segmentation is high. The exchange rate affect is not present
in the case of greenfield investments, a result that further strengthens the asset
acquisition hypothesis, as access to proprietary assets is not relevant in this form
of FDI.

Appendix A: Random effects negative binomial model

The Poisson distribution is widely used in analyzing count data where the depen-
dent variable is discrete and defined for non-negative integers corresponding to
the number of events occurring in a given interval (Hausman, Hall, and Griliches
1984).
   The objective is to empirically model the determinants of the number of U.S.
mergers and acquisitions. The Poisson probability function may be expressed as
follows:
                       y 
   Prob(yit ) = e−λi t λitit yit !

where y it is the number of acquisitions of M&As of firms in the SIC code i in
period t, and λ it is the conditional mean and variance. Standard procedure is to
470    G.J. Georgopoulos

make λ it to be an exponential function of the explanatory variables:

   λit = exp(Xit β).

The coefficients are estimated by maximizing the log-likelihood function of the
Poisson model. As noted, this model has the property that the conditional ex-
pected value and variance are equal. This condition is violated in many data sets.
To overcome this condition, the negative binomial (hereafter Negbin) model has
been developed for cross-sectional data (Cameron and Trivedi 1986). It allows
for the second conditional moment to differ from the first. In many economic
applications it is not uncommon to find that the variance exceeds the mean. This
implies ‘overdispersion’ in the data. Overdispersion may have two explanations.
First, it may be caused by unobserved heterogeneity. Second, the data-generating
process may be such that there is interdependence between the occurrence of suc-
cessive events. In the presence of overdispersion, employing the Poisson model
will lead to an estimated variance-covariance matrix that is biased downwards,
yielding incorrectly small estimated standard errors of the parameter estimates
and overstated t-statistics.
   The Negbin model allows for heterogeneity in the mean function by introduc-
ing an additional stochastic component to λ it :

   λit = exp(Xit β + εit ),

where εit captures unobserved heterogeneity and is uncorrelated with the explana-
tory variables, and exp (ε) follows a gamma distribution.
    A concern with the standard Negbin model is that it does not take into ac-
count the panel nature of the data used here. The Negbin model pools the data
where it constrains the dispersion to be constant across all panels. In contrast,
heterogeneity across panels or industries is allowed by employing the random ef-
fects Negbin model proposed by Hausman, Hall, and Griliches (1984). 14 In this
model, the dispersion varies randomly from industry to industry. Specifically, the
Poisson parameter λ it follows a gamma distribution with parameters (γ , δ). For
the variation across industries, we allow each industry i to have its own δ i such
that 1/(1 + δ i ) is distributed as a Beta random variable with the shape parameters
(a, b). 15 For any industry i, the dispersion (variance divided by mean) is equal to 1
+ δ i . As is standard, we set γit = exp(X it β). Hausman test results and fixed-effects
results are also presented.

14 Hausman, et al. (1984) states that the RENegbin model yields asymptotically more efficient
   estimators than their fixed effects model. For these results to be consistent, the industry-specific
   effects need to be uncorrelated with the regressors.
15 The Beta distribution will be symmetric if a = b, and can be U-shaped or hump-shaped.

Appendix B: Data sources

B.1. U.S. M&A and Greenfield Investments in Canada
Count data on U.S. mergers and acquisitions of Canadian firms are from the
Investment Review Division, Industry Canada. The data record the transactions
involving U.S.-owned businesses merging or acquiring Canadian-owned business
in Canada. According to the Investment Canada Act, section 26, a merger or ac-
quisition relates to a change in control, where control is defined as acquiring
at least 50% of common voting stocks or assets. The act requires every non-
Canadian to file a Notification or an Application for Review with Investment
Review, Industry Canada, each time a non-Canadian plans to or actually com-
mences a new business activity in Canada (greenfield investment) or acquires
a Canadian business. Applications for Review are necessary for relatively large
transactions (in excess of $218 million for WTO members and $5 million for
non-WTO members), and, upon receipt, the minister of finance will determine
whether the investment is permitted. Authorities at Investment Review contact
the potential investors within a specified period after the submission of forms to
determine whether the transaction was implemented. The recorded acquisition
data reflect those applications where the investment was actually carried out. All
the Notifications are recorded in the data, but there is no follow up process for
the Notifications. Thus, there may be an upward bias on the number of invest-
ments in this category. However, authorities at Investment Review estimate that
the vast majority of Notifications are submitted after the investment has taken
place. The data do not distinguish between mergers and acquisitions. The full
sample size ‘All industries’ in table 3 consists of 400 panels of balanced data over
the years 1985–2001 (6,800 observations), where the panels used were determined
by the fixed-effects estimation methodology (see footnote 5 on the choice of the
restricted sample set).
   For the Canada-U.S. real exchange rate, the nominal exchange rate data e are
from CANSIM I and are annual averages. The 2-digit U.S. industry price data
are from the Bureau of Labour Statistics, Industry Prices. The Canadian prices
are from CANSIM I, Industrial Product Indices. Concordance tables were used
to match Canadian 1980 SIC codes with U.S. 1987 SIC codes.
   The tariff variable is the effective tariff rate at the 4-digit SIC level. This is
equal to the ratio of the value duties collected on U.S. imports at the 4-digit
SIC level to the value of U.S. imports at the 4-digit SIC level. The source is the
