Empirical organizational‐level examinations of agency and collaborative predictions of performance‐contingent compensation

Competitive predictions regarding the relationships between: (a) monitoring and agent tenure, and (b) performance‐contingent compensation are derived from agency theory and collaborative perspectives. These results are tested in a within‐industry (trucking) sample and in a cross‐industry sample. The results partially support both perspectives, particularly with respect to monitoring and agent tenure. Implications of the results for theory and practice are discussed.

International comparison of returns from conventional,industrial and 52-week high momentum strategies

The performance of industrial and 52-week high momentum strategies is compared to the conventional strategy, using a large sample of stocks drawn from multiple countries covering a quarter of century to 2007. The sample of 51,879 stocks in 51 countries removes the potential for criticism, such as data mining, and provides more generalisable findings and knowledge concerning the robustness and usefulness of return from momentum strategies. Both the industry and 52-week high strategies generate positive returns but neither is greater than the conventional momentum strategy. A new 52-week high industry momentum strategy is examined and it achieves a similar result.     

Are short‐term effects of pollution important for growth and optimal fiscal policy?

We study optimal fiscal policy in a stock‐flow model of the environment within an endogenous growth framework, where some pollutants have a lasting impact on environmental quality which is restored through abatement expenditure, while others dissipate and hence, have a short‐term effect on the environment. All pollutants, however, affect the productivity of a public good negatively. Given that short‐term pollution, although it dissipates, is irreversible in this sense, a government cannot ignore its negative effects since this type of pollution lowers the productivity of all inputs. We find that a larger negative effect of short‐term pollutants as well as a higher congestion effect of private capital leads to corrective fiscal policies with higher optimal income tax and abatement expenditure rates, which have favorable growth consequences. Interestingly, we find that the rate of short‐term pollution does not affect optimal fiscal policy while that of the long‐term pollution does.     

An application of the monetary approach to black market exchange rates

Zusammenfassung Eine Anwendung des monet?ren Ansatzes zur Erkl?rung von Schwarzmarkt-Wechselkursen. — Dieser Aufsatz entwickelt einen monet?ren Ansatz zur Analyse der Schwarzmarkt-Wechselkurse unter besonderer Berücksichtigung Indiens. Der Gleichgewichtskurs auf solchen M?rkten wird in einem Modell durch die Bedingungen des Bestandsgleichgewichts bestimmt. Berücksichtigt wird dabei das m?gliche Zusammenwirken zwischen dem Schmuggel und dem Schwarzmarkt für Devisen. Die empirischen Sch?tzungen lassen vermuten, daΒ die Ausweitung der Geldmenge im Inland und der internationale Goldpreis neben anderen Faktoren einen bedeutenden EinfluΒ auf den Schwarzmarkt-Wechselkurs in Indien haben.

Résumé Une application de l’approche monétaire aux taux de change sur le marché noir. —Cet article développe une approche monétaire pour l’analyse des taux de change sur le marché noir en considération particulière de l’Inde. Dans le modèle, le taux de change d’équilibre sur le marché noir est déterminé par les conditions d’équilibre de stock. Le modèle permet l’interaction possible entre la fraude et le marché noir pour les monnaies étrangères. Les estimations empiriques suggèrent que l’expansion monétaire locale et le prix mondial d’or (complémentairement aux autres facteurs) ont une influence significative sur le taux de change sur le marché noir indien.

Resumen Una aplicación del aprocha monetaria a las tasas de cambio del mercado negro. — En este artículo se desarrolla un aprocha ?monetaria? para el análisis de las tasas de cambio del mercado negro con especial referencia a la India. En el modelo, el equilibrio de la tasa de cambio del mercado negro se determina por las condiciones del equilibrio de stock. Se permite una posible interacción entre contrabando y mercado negro de monedas extranjeras. Las estimaciones empíricas sugieren que la expansión monetaria doméstica y el precio mundial del oro (agregados a otros factores) tienen una influencia significativa sobre la tasa de cambio de mercado negro en la India.

     

In-house R&D management development — strategy and implementation in a major government R&D agency

Abstract
The paper describes the experiences of CSIR in developing an in-house capability and implementation process of R&D management development programmes. The conceptual approach of the laboratory-based R&D management development programmes is described. Different phases in the process of implementation are presented along with the case studies of recent training programmes in two different laboratories. Some of the key aspects of the training programmes —- successful implementation, relationship with policy-making, and improving R&D performance have been examined. The role of international co-operation in R&D management development is suggested. The paper also discusses the future prospects of R&D management development programmes in the country.     

Estimating Direct Gains in Consumer Welfare in Telecommunications Sector

This paper discusses the benefits of product and process innovation as well as deregulation in consumer telecommunication products markets. The twin trends of price reduction and new features have benefited consumers. These major changes have taken place alongside deregulation. Using the data from Organisation for Economic Co-operation and Development telecommunication reports, the paper provides estimates of gains in consumer welfare over the years. These direct gains are significant (hundreds of billions of dollars) and thus justify the public investment that goes into the telecommunication infrastructure improvement.     

NOTES AND MEMORANDA INCOME, CONSUMPTION AND SAVING IN URBAN AND RURAL INDIA: A NOTE

In a recent issue of the Review of Income and Wealth [1], Uma Datta Roy Choudhury presented some results on consumption and saving functions in India. While the study is interesting, some of the results are quite peculiar. Thus she reports a marginal propensity to save of 0.88 for the urban sector, an abnormally high figure. Other available evidence points to a much lower figure. Again she reports a negative marginal propensity to consume out of permanent income for urban households. This makes no economic sense. Furthermore her attempts at explaining urban consumption behaviour are not very successful. In this paper, we shall show that these suspicious results are the consequences of the measurement and definitions of the variables, and the specification of the functions. Once these shortcomings are removed, we obtain more satisfactory and more plausible results.
In the first section we present a critique of Mrs. Roy Choudhury's article. In the second section we present our results. The last section summarizes the conclusions.     

A general class of estimators for estimating population mean using auxiliary information

Summary A general class of estimators for estimating the population mean of the character under study which make use of auxiliary information is proposed. Under simple random sampling without replacement (SRSWOR), the expressions of Bias and Mean Square Error (MSE), up to the first and the second degrees of approximation are derived. General conditions, up to the first order approximation, are also obtained under which any member of this class performs more efficiently than the mean per unit estimator, the ratio estimator and the product estimator. The class of estimators in its optimum case, under the first degree approximation, is discussed. It is shown that it is not possible to obtain optimum values of parameters “a”, “b” and “p”, that are independent of each other. However, the optimum relation among them is given by (b−a)p=ρ C _y/C _x. Under this condition, the expression of MSE of the class is that of the linear regression estimator.     

The effect of time-varying covariances on asset risk premia

In this article we examine an intertemporal capital asset pricing model (CAPM) that allows for time-varying conditional covariances that are assumed to follow a multivariate integrated generalized autoregressive conditional heteroscedastic (IGARCH) process. The resulting pricing equation includes idiosyncratic risk premia in addition to the usual market beta. Empirical analysis based on ten size and ten industry portfolios reveals significant idiosyncratic premia for most portfolios. Overall, we reject the static CAPM in favor of the intertemporal CAPM.     

R & D and marketing dialogue in high-tech firms

Based on an empirical study of more than 200 R & D and marketing managers from high-technology companies, we conclude that (1) there is a great deal of consensus between R & D and marketing managers on the relative importance of the areas requiring integrated efforts; (2) companies successful in their new product program achieve a significantly greater degree of R & D marketing integration; (3) company size does not affect the level of integration achieved; and (4) the companies that achieve a high degree of R & D/ marketing integration do so by concentrating on all 19 areas proposed in the article and do not merely focus on a few key areas.
