WORLD OUTLOOK

At the end of 1982 output in the world economy was still falling, although there were signs that the decline had very nearly run its course. We expect a radual recovery to begin in the first half o f 1983. Unlike the recovery which began in the late summer of 1980, when inflation was still in double figures, any upturn in 1983 would be set against a background of declining inflationary expectations and weak oil prices. IJ. as we expect, a falling inflation rate proves a decisive factor in keeping interest rates on a downward path, we forecast that the output will gather pace in I983 and rise reasonably strongly in 1984. Of the 4 per cent rise in industrial production which we foresee in 1984. a large part is due to the fall in real oil prices.     

Nuclear nightmares in the Philippines

The construction of the Philippine's first nuclear power plant by Westinghouse has come to symbolize the corruption and cronyism of the Marcos' years. The plant has created so much controversy that it has yet to operate, in a country that desperately needs electrical power. The entire affair suggests that American multinationals cannot simply adopt the business practices of the host country, but instead must carefully analyze the political and business environments of their foreign based operations, and then take into account the long-term ethical implications of their decisions. The case also suggests that government needs to play a more active role in regulating multinationals, especially when sophisticated and potentially dangerous technologies are involved.William Beaver is currently an associate professor of social science at Robert Morris College which is located near Pittsburg PA. He has published a book (Nuclear Power Goes On-Line, Greenwood Press, 1990) and several articles on the subject of nuclear power. He teaches a business and society course in the college's MBA program, which has developed his interest in business ethics and its relationship to nuclear power.     

Note on the behavior of residual security returns for winner and loser portfolios

Portfolios are formed directly and exclusively upon residual return behavior in the months prior to portfolio formation. The empirical behavior of residual return in the post-formation period is then examined. Based upon the overall time period studied (1932 through 1977), the average residual return is essentially zero in the months subsequent to the portfolio formation. However, systematic (i.e., non-zero) residual behavior is observed in particular years. Moreover, the results suggest the possibility that ‘abnormal’ returns observed after certain events (e.g., earnings announcements) may at least in part reflect more general phenomena associated with being ‘winners’ and ‘losers’ in terms of residual returns in the months previous to the event.     

WORLD OUTLOOK

The strength of US domestic demand is exerting a very strong pull on the world economy. Japan in particular is benefiting from soaring export demand, but the effects on European exports have been offset by weak domestic demand and, in the case of West Germany and the UK, by damaging industrial disputes which have interrupted supply. Over the next 12 months we expect the US economy to slow down under the weight of the financial and external balance pressures, which two years of very rapid but unbalanced growth have built up. For the world economy, however, we expect the slowdown in the US to be counterbalanced by expanding domestic demand in Europe and Japan, especially if a lower dollar permits reductions in interest rates. We forecast world output growth of about 3 per cent next year, well below the near-5 per cent projected for 1984 - the cyclical peak. By the second half of 1985 the world recovery will be three years old and we expect a pause in the growth of output. Against a background of stable monetary growth we expect world inflation in the 5–6 per cent range over the medium term. This is consistent with some increase in US inflation, low and stable inflation in Japan and West Germany and further progress in reducing inflation in countries such as France and Italy. Our forecast is based on the assumption that the dollar falls next year. If it does not fail we believe there is a significant risk of slower growth.     

The Volatility and Transmission of Equity Returns among the G-7 Countries: the post-Bretton Woods experience

This paper models the volatility of national stock market returns of the G-7 countries using ARCH and GARCH modeling techniques. Then, via the use of vector autoregression analysis, the international transmission of volatility among the countries is explored for the period between April 1973 and July 1990. Variance decompositions are calculated in order to quantify the impacts of volatility shocks in one market on the others. Impulse response functions are used to inspect the dynamic responses of domestic and foreign volatility shocks. Results indicate that volatility transmission among the G-7 countries is the norm in the post-Bretton Woods era. Further, we find that volatility shocks are generally absorbed within six to nine months.
