Marginal q,Tobin's q,Cash Flow,and Investment

Many studies of the determinants of investment use Tobin's q to control for the investment opportunities of a firm. Tobin's q roughly measures the average return on a firm's capital anticipated by the market. More relevant for investment decisions, however, is the marginal return on capital. In this paper we estimate investment and research and development (R&D) equations using a measure of marginal q. We use marginal q to identify the existence of cash constraints and managerial discretion and as a separate explanatory variable. For a sample of 560 U.S. firms observed over the 1977-1996 period we present evidence confirming the existence of both cash constraints in some companies and managerial discretion in others.

Changes in market concentration of manufacturing industries

The impact on concentration of advertising and other variables is examined in a multiple regression model. The findings indicate that the positive influence of advertising observed for earlier periods continued during 1972–1977. By testing hypotheses suggested by other researchers, this paper resolves most, if not all, of the seemingly conflicting findings of researchers examining changes in concentration since 1963. The findings also strongly suggest that lagged models provide little, if any, added insight into the causes of changes in concentration.     

U.S. merger policy and the 1992 Merger Guidelines

This article reviews the empirical evidence regarding the effects of mergers on corporate efficiency. In light of this evidence it then evaluates the effectiveness of U.S. merger policy as articulated in the 1992 Guidelines of the Department of Justice. It argues that the 1992 Guidelines and the U.S. Government's policies toward business more generally over the past 12 years have been characterized by a bias for bigness. It concludes that this bias will only be eliminated when government authorities in charge of merger policy recognize that many mergers lower economic efficiency and design and enforce their policies accordingly.     

The term structure of inflation expectations

We use information in the term structure of survey-based forecasts of inflation to estimate a factor hidden in the nominal yield curve. We construct a model that accommodates forecasts over multiple horizons from multiple surveys and Treasury real and nominal yields by allowing for differences between risk-neutral, subjective, and objective probability measures. We establish that model-based inflation expectations are driven by inflation, output, and one latent factor. We find that this factor affects inflation expectations at all horizons but has almost no effect on the nominal yields; that is, the latent factor is hidden. We show that this hidden factor is not related to either current and past inflation or the standard set of macro variables studied in the literature. Consistent with the theoretical property of a hidden factor, our model outperforms a standard macro-finance model in its forecasting of inflation and yields.     

Employee job satisfaction in developing countries: The case of Kenya

Although developing countries that rely on agriculture continue to invest considerable amounts of resources toward the training of qualified agricultural manpower, the intensification of agricultural research, and the development of favourable agricultural policies, little attention is given to the organizational and social structure of the workplaces of the technical workers in agriculture. We argue that an understanding of what produces satisfied agricultural technicians is important in its own right, but is also important for indirectly increasing agricultural production in these developing countries. Following a social exchange theoretical argument, and using a national sample of technically trained agricultural personnel in Kenya, we identify the factors in the workplace that affect job satisfaction. Implications for management are drawn from these findings.
