FACTORS INFLUENCING CHOICE OF DISCIPLINE OF STUDY — ACCOUNTANCY,ENGINEERING, LAW AND MEDICINE

This paper examines the factors which influence high calibre students in their choice of a professional discipline of study. Using a questionnaire approach students were requested to determine the relative importance of eleven factors in their choice of discipline of study. Results showed that accountancy students appeared most concerned with job satisfaction, earnings potential, availability of employment, aptitude for subject and years of formal education, and to have a different, and more distinctive, profile than that of other students. These results may have important implications for recruitment into the profession.     

Path analysis for mixed qualitative and quantitative variables

In this report path analysis models are considered for mixed qualitative/quantitative variables. Only endogenous variables that are dependent in all its relations are supposed to be quantitative, but this restriction can easily be dropped. Qualitative variables are handled using a dummy-variable for each category. Parameters are estimated by ordinary least squares. The method allows decomposition of total effects in direct and indirect effects, which makes interpretation easier.     

A DYNAMIC ANALYSIS OF US EXPORT WHEAT PRICING AND MARKET SHARES

The economics of a higher loan rate to support US wheat prices is analysed. Utilising optimal control theory, a dynamic wheat trade model is developed. The basic premise underlying the model is that the United States finds itself having transient monopoly power in the wheat market. An expression for the optimal pricing policy which maximises the present value of expected profits over the indefinite future is derived. Results from both the theoretical and empirical models demonstrate that the US wheat pricing strategy depends on its costs relative to competitors' costs, the discount rate and the competitors' response function. The main policy implication of the analysis is for the dominant wheat exporting country constantly to seek to lower costs relative to competitors and to maintain a price exceeding unit cost without encouraging competitors' expansion.     

A Test of the Debt-Monitoring Hypothesis: The Case of Corporate R&D Expenditures

Studies that test for shareholder wealth effects of announcements of plans to increase R&D expenditures find an average positive effect, but also a significant cross-sectional variation. This study determines whether the effect can be predicted when the announcing firm's capital structure is considered. Results suggest a positive relation between the debt ratio and the R&D induced abnormal stock returns. These results are robust using different industry-adjusted and unadjusted measures of capital structure and while controlling for several potentially influential variables. In addition, the gains to shareholders do not seem to be wealth transfers from bondholders. This evidence provides support to the debt-monitoring hypothesis.     

THE WEALTH EFFECTS OF ANNOUNCEMENTS OF R&D EXPENDITURE INCREASES

We examine the effect of announcements of plans to increase R&D expenditures on the stock price of rival firms. We test two alternative hypotheses: the first-to-innovate hypothesis versus the free-rider of spillovers hypothesis. Analysis of 114 announcements of increases in R&D expenditures indicates that rival firms suffer a statistically significant negative abnormal return at announcement, which supports the first-to-innovate hypothesis. This result provides a rationale for the potentially costly voluntary disclosure of R&D expenditures. A cross-sectional analysis of the abnormal returns to rival firms reveals that a highly credible announcement has some spillover effects, and that the rival firm earns a much smaller but positive abnormal return. An important implication is that it is always strategically beneficial for the firm to disclose its future R&D plan.     

An econometric assessment of the Canadian wage and price control program: 1975:4–1977:4

This paper presents an econometric assessment of the Canadian Wage and Price Control Program. The assessment is specifically designed to determine whether controls have been effective in reducing the long-run inflation rate in Canada. The method of evaluation of the control program is to compare the behavior of inflation under controls to the behavior which would have occurred in the absence of controls. In addition, the paper analyzes inflation in the post-control period to test for the “catch-up” phenomenon. The results suggest that the control program exercised a permanent effect on the inflation rate.     

Effects of prevailing wage laws on municipal government wages

A number of authors have suggested that prevailing wage laws tend to raise the wages of covered employees. Yet, no one has previously tested this hypothesis directly. In OLS regressions the prevailing wage law is found to have a negative effect that is not statistically significant. In a two-stage procedure the effect is found to be positive and statistically significant in the preferred formulation. Further tests provide additional evidence that the existence of prevailing wage laws is responsive to economic conditions.
