GLOBAL TRANSFER OF ARMS TECHNOLOGY AND ITS IMPACT ON ECONOMIC GROWTH

The Malmquist index is used to measure the impact of military technology transfer on economic growth. This index can be decomposed into two components: efficiency change and technical change. Given the aggregate production function, the effect of technology diffusion on growth is measured by efficiency change. The shift in aggregate production function due to innovative activities is measured by technical change. An analysis of 16 American and European countries over the period 1978-1994 reveals that the total impact of arms trade on growth, measured in terms of the Malmquist index, varies across countries. Contrary to common belief the findings of this study do not suggest that industrial countries have more efficient utilization offoreign military technology than do developing countries. The evidence also shows that the difference in total impact among countries is primarily due to the differences in efficiency change, not technical change.     

Black Female Clerical Workers: Movement toward Equality with White Women?

This article examines the occupational mobility patterns of black and white female clerical workers from 1972 to 1980. Black women were initially concentrated in the lower-paying clerical positions and were less likely than white women to leave for better jobs in other areas. Those black women who had relatively good clerical jobs tended not to rise any further and even experienced some difficulty in maintaining their occupational status. Education and training aided occupational mobility less for black women than for white women.     

The Distribution of Foreign Exchange Price Changes: Trading Day Effects and Risk Measurement

This study investigates the nature of price changes in a variety of major and minor foreign exchange markets. The results suggest that the log of price changes over one (trading) day intervals seems to follow a non-normal stable distribution function. Different measures of location (and to lesser extent scale) are present for different days of the week. Dollar denominated price changes are high on Mondays and Wednesdays and low on Thursdays and Fridays for all currencies. The Wednesday-Thursday result is consistent with the settlement procedures used in foreign exchange transactions in the dollar. The Friday-Monday result is consistent with an increase in demand for the dollar prior to the weekend.     

The Collective Household, Household Production and Efficiency of Marginal Reforms

Most research on the welfare properties of taxes employs the unitary model of the household, ignoring household production. A simple model provides expressions for the changes in individual utility given marginal reforms to government policy. It is shown that the burden of a higher tax on household goods falls on the household member that consumes more than they produce or purchase. Numerical calculations show that price substitution (complementarity) between home and market labor increases (decreases) aggregate efficiency costs of a marginal redistribution of income without impacting the intra-household distribution of utility changes. Modeling household goods as public versus private can alter the distributional consequences of marginal reforms.     

Conditional Earnings Conservatism and Corporate Refocusing Activities

We extend standard models of conditional earnings conservatism and adaptation value to the context of the corporate refocusing activities of UK listed companies. This analysis is interesting because refocusing activities are: (1) commonly anticipated by significant negative returns in the financial year(s) before the refocusing event; (2) typically associated with large material charges; and (3) likely to be part of a strategic plan with the internal decision preceding the formal public announcement. We complement Burgstahler and Dichev [1997] by showing how their nonlinear relation between share prices and earnings changes around refocusing events as adaptation options are exercised. Because refocusing events also involve large realized losses and major changes to firms’ strategic plans, we expect to see systematic changes in the timing relations between stock returns and reported earnings. To capture this, we show how the coefficients of Basu's [1997] model of conditional conservatism change around refocusing events.
