This study examines cost structure for the provision of health care in college and university student health centres. Empirical estimates of a translog cost function for 81 American College Health Association member institutions show economies of scale in the production of student health care.

This paper empirically analyses the impact of the unemployment insurance system upon the insured unemployment rate and the average duration of unemployment. It employs a simultaneous equation framework because of possible feedback effects between the insured unemployment rate and the average...

This paper considers the relationship between cointegration and causality and uses tests of cointegration as pre-test for Granger tests of causality. The analysis is employed in analysing the government budget-inflation relationship in Greece. Empirical evidence suggest that there is a long-run...

This paper considers the degree of measurement error in estimates of required schooling for jobs and the bias created by errors when estimating the returns to overeducation. Using the Panel Study of Income Dynamics, it finds substantial differences between estimates of required schooling. Thus...

We apply recent time series techniques to Mbaku's Cameroon data to investigate the effects of foreign aid on economic growth. In contrast to Mbaku, we find some evidence to support the foreign aid led growth hypotheses in Cameroon. Our results illustrate the importance of testing hypotheses in...

This paper demonstrates that the Granger-causality tests are not affected by an accounting identity relationship. In the context of exports and economic growth relationship, this amounts to saying that if a Granger-causal relationship from exports to output is detected, this cannot be due to a...

Mbaku (1993, 1994) presents empirical evidence to support the hypothesis that in Cameroon, during 1971-90, foreign aid had no impact on economic growth. In this note, we apply the recent technique of unit-root testing and Johansen's maximum likelihood procedure to show, on the contrary, that...

The United States banking industry experienced a period of poor performance in the late 1980s. Significant problems with loans as reflected in loan loss provisions and net charge offs hampered bank profitability. We examine the effect of portfolio composition on net charge offs at large...

This paper investigates the robustness of the Friedman hypothesis that states the volatility of money growth influences the velocity of money. Using data for Japan the Granger-causality method is implemented to test for the effect of the variability of the Japanese monetary aggregate M2+CDs on...

This paper tests the impact of international investment restrictions on closed-end country funds in four Asian countries - Hong Kong, Korea, Singapore and Taiwan. The results show that the relationship between the premiums or discounts on closed-end country funds and announcements of changes in...
