Abstract
currencies over the last two decades. During the same time Japan has become
one of the world's largest providers of FDI. Japan's share of total FDI
outflows increasedfromabout 6 percent during the late 70's to 21 percent in
1990 while its share of the total stock of FDI in the world increasedfromless
than 1 percent in 1960 to more than 13 percent in 1993. Not surprisingly,
Japan's role in international business in general and its FDI activities, in
particular, have attracted considerable attention from researchers world
wide. However, much of this attention has been directed towards the patterns
and determinants of Japanese foreign direct investment, in particular to the
United States. The impact of changes in the value of the Yen on Japanese
FDI has been largely overlooked. Thus, this paper fills an important gap in
the literature by focusing on the influence of changes of the exchange rate
on Japanese foreign direct investment. A comprehensive simultaneous equa-
tion model of Japanese FDI is developed on a regional level to gauge the
extent to which currency fluctuations affect Japanese FDI activities. The
results suggest that the exchange rate is an effective mechanism through
which to influence FDI. Thus, the exchange rate should not be overlooked
by the World Trade Organisation in its efforts to further liberalise investment
through the Multilateral Agreement on Investment.

adjust the value of the Yen as a means of controlling the Japanese balance Impacts of

same time the Bretton Woods system of fixed exchange rates collapsed
followed by a devaluation of the US dollar the same year. The resulting
Smithsonian Agreement reset the exchange rate to 308 Yen per US dollar; a
rate which proved difficult to maintain and the longstanding system of fixed
exchange rates was abandoned in 1973 as the major western industrialised
countries allowed their exchange rates to float (Army Area Handbooks,
1993).

Concerns with United States' growing trade deficit with Japan, thought
to be due to the weakening of the Yen, led the G5 countries to adopt a policy
aimed at the appreciation of the Yen and the deutschmark relative to the
dollar in 1985. This agreement, termed the Plaza Accord, set a short -term
target of a 10% to 12% depreciation of the US dollar relative to the Yen and
considered that a further long-term depreciation of the dollar was also
desirable. Over a six week period each of the G5 countries used their foreign
exchange reserves to intervene in currency markets to achieve the desired
effect. As a result, the competitiveness of Japanese exports fell by 29% (Das,
1993). By 1987 the major currencies were within ranges which were consis-
tent with economic fundamentals and, with the Louvre Accord, the G5
countries agreed to work together to maintain exchange rates at approxi-
mately the currentlevels.Despite this agreement, the stock market crash later
that year led to a depreciation of the dollar and an appreciation of the Yen
(Das, 1993).
Japan has also made unilateral attempts to reduce its substantial trade
imbalance, using both monetary and fiscai policies. In the late 1980s an
easing of monetary policy was aimed at increasing domestic demand (and
imports) (Bergsten & Noland, 1993). Although demand increased substan-
tially, the low interest rates which were an element of Japan's expansionary
monetary policy in this period led to a depreciation of the Yen which more
than counteracted the effect of increased domestic demand on the trade
balance. The bubble economy which resulted from this monetary policy
eventually burst by acute monetary tightening, leading to a recession in the
early 1990s. This recession, coupled with the depreciating Yen, caused the
trade surplus to continue to grow. In the aftermath of the collapse of the
bubble economy the government switched to fiscai policies to stimulate the
economy and reduce trade imbalances. One effect of this was to increase
domestic interest rates, thereby leading to a renewed appreciation of the Yen
(Bergsten & Noland, 1993).
The information in Figure 1 show the stock of Japanese FDI and the
value of the Yen in terms of the US dollar. Clearly, the Yen has appreciated
consistently over the 1970 -1993 period. In 1970, the US dollar was worth
approximately 360 Yen. By 1993, the US dollar was worth only about 110
Yen; representing an appreciation of the Yen of approximately 70 percent.
During the same time, the stock of Japanese FDI has also increased substan-

extent to which the appreciation of the Yen has contributed to the phenome- Impacts of

significant determinants of Japanese total FDI outflows.

The relationship between the current account balance and FDI flows is
relatively straightforward. Concern with controlling foreign exchange re-
serves following World War II led the Japanese government to restrain FDI
outflows through legislation controlling foreign exchange transactions (Tak-
agi, 1995). In the early 1970s, when the current account balance seemed
destined to remain in surplus, the Japanese regulatory stance toward outward
FDI began to relax. Throughout the 1970s regulations controlling outward
flows of capital, including FDI, varied according to the direction of pressure
on the exchange rate. When the Yen was appreciating outward investment
was encouraged, and during periods of depreciation outward investment was
discouraged (Takagi, 1995). For example, when the value of the Yen in-
creased dramatically following the Plaza Accord in 1985 the Ministry of
International Trade and Industry (MITI) determined that a specific amount
of industrial investment abroad would be more beneficial than domestic
investment, in terms ofjob creation and long-term economic benefits, and
drafted a plan for restrucruring of Japanese domestic industry through FDI
(Doner, 1993).
Changes in the exchange rate also affect FDI flows. As described above,
the exchange rate affects the balance of trade which, in turn, stimulates
regulatory changes aimed at controlling FDI flows. Changes in the exchange
rate also have more direct affects on FDI flows. The most direct link between
the exchange rate and FDI is through the affect exchange rate changes on the
price of export goods. An appreciation of the Yen raises the cost of produc-
tion in Japan, thereby making many Japanese products less competitive in
world markets. Many firms, particularly those in declining industries, re-
spond to these competitive pressures by relocating to countries where pro-
duction costs are lower.
The appreciation of the Yen has also encouraged Japanese FDI indi-
rectly by creating a surplus in Japan's trade balance. Consequently, explicit
alised countries. Japanese stock of FDI in the US and Europe accounts for
approximately 60 percent of the total stock of Japanese FDI in the world.
Most attempts to analyse FDI so far have focused on the determinants of FDI
from a firm perspective. Although this type of analysis provides valuable
information, it still does not provide a comprehensive picture. This is because
FDI is also highly influenced by external factors. Firm's decisions to invest
overseas are based on an understanding of the macro environment and its
effects on FDI and the business as a whole.

Direct Investment
In this paper it is hypothesised that FDI follows the Nerlovian partial
adjustment process which assumes that there is an optimal, desired long run
amount of FDI. It is assumed that collectively firms aim to achieve a desired
stock of capital in their foreign investment portfolio at a given point in time.
This desired stock of FDI ( FDIt* ) is specified as a linear function of the
current account balance x as follows:
Downloaded by MAHIDOL UNIVERSITY At 09:07 07 March 2015 (PT)
where FDIt is the actual FDI stock at time t and d is the coefficient of
adjustment.
Equation (2) postulates that the actual change in FDI in any given time
period t is some function δ of the desired change for that period. If δ = 1 it
means that actual stock of FDI is equal to the desired stock. If δ = 0 there is
no change in the stock of FDI over time. Typically δ will be between 0 and
1 since achievement of a desired level is likely to be incomplete because of
rigidity and contractual obligations.
Equation (4) is the partial adjustment model and represents the short run
demand for FDI. Once equation (4) is estimated, one can derive the long run
function, equation (1), by estimating the adjustment coefficient δ and com-
bining equations (1) and (4).
The overall model is estimated using annual data for the period 1970
-1993. Given the structure of the model which assumes that FDI in one region
is influenced by FDI activities in other regions, we estimate the overall model

dynamic simulations of these models also reveal that these models perform
reasonably well in tracking historical values of Japanese stock of FDI over
the sample period judging by the performance statistics summarised in Table

Using the parameter estimates, the models are simulated under various
scenarios in order to assess the extent to which changes in the exchange rate
affect the levels of Japanese stock of FDI to the year 2000. The three
scenarios considered are:

on an assumption that the Japanese external adjustment is nearly Fluctuations on

The results show that Japanese stock ofFDI continues to increase, albeit
at a slower rate, with the depreciation of the Yen. This phenomenon cannot
be explained by appreciating assets in the host country because we have not
included asset appreciation as a component of our FDI stock variable.
Similarly, we cannot explain continuing FDI growth in terms of retained
earnings because these are also not included in our FDI variable. One
possible explanation is that in some instances FDI is undertaken as a means
of compensating for shrinking exports. In this case the depreciation of the
Yen should Iead to an increase in exports, thereby reducing some of the
incentives to undertake FDI. Another explanation may be that investment
opportunities in Japan may be diminishing so that Japanese firms looking for
growth opportunities are forced to invest abroad despite relative adverse
circumstances.
