THE STOCK PRICE REACTION TO SUPPLY CHAIN MANAGEMENT ADVERTISEMENTS AND COMPANY VALUE

The research examines the stock price reaction to the announcement of the adoption of supply chain management‐enhancing tools and technologies to determine whether there is a significant response from the capital markets. The results show that the adoption of supply chain management‐enhancement tools appears to be value creating. The strength of the stock price reaction is positively related to the degree of certainty regarding the publication date of the publication.     

Grains — more or better storage?

From time to time attention is directed to startling losses in livestock and crops caused by parasites and diseases, many of which occur during storage.¹ It is important that the losses be reduced. Reduction of losses in storage in particular: (a) makes more food available from a given amount produced; (b) makes more of it available for the poor, who suffer most from shortages; and (c) makes it available at the time of greatest scarcity, before the next production season or harvest.² It is, however, equally important that resources should not be wasted in misguided efforts to reduce waste. In the normal condition of cruelly restricted resources, these should be used to reduce waste only if the return in doing so is as good as, or better than, in other activities.     

Dynamic tariffs with asymmetric information

Recent developments in dynamic game theory are applied to determine when two countries can sustain freer trade given that they determine trade policies non-cooperatively. Countries know their own level of protection, but not the other country's level of protection. Using import trigger strategies, cooperation (in the form of low tariffs) can be supported, although there are periodic reversionary (high tariff) episodes. However, if terms of trade trigger strategies are used, cooperation does not occur.     

DURATION,IMMUNIZATION, AND HEDGING WITH INTEREST RATE FUTURES

The recent advent of the interest rate futures markets has greatly enriched the hedging opportunities of market participants faced with undesired interest rate risk. The variety of futures contracts presently spans a number of instruments with different risk, maturity, and coupon characteristics. This paper modifies the concept of duration and extends the duration hedging approach to cases where futures contracts are used as the hedging instrument. The derived hedge ratios take into account differences in coupon, maturity, and risk for three different regimes. Usage of these hedge ratios should lead to more efficient hedging of interest rate risk.     

The firm's investment and employment policy through a business cycle

The paper studies with the help of a model the investment and employment policy through a business cycle for a firm which maximizes its discounted income and assumes that the forecasts are perfectly correct. In addition to investment and wages costs, the firm has to bear recruitment and firing costs; it has at its disposal four control variables: the selling price, the recruitment rate, the firing rate and the investment rate. The firm's strategy appears to be generally a sequence of elementary policies. This sequence highly depends on the relative values of parameters like the rate of depreciation of equipment, the natural rate of decrease of employment, the ratio of the unit recruitment and firing cost with respect to the wage rate, the rate of decrease of demand during recession. The results obtained are, on the whole, quite consistent with the behaviours which have been observed in the last years, and explain some of the features of recessions.     

Human resource management strategies in declining industries

The conceptualization presented in this article suggests that top management should take into account the role of the human resource function in formulating and implementing strategic responses to decline. Such responses must be formulated within the context of the skills and knowledge available to the organization and according to the type of environmental conditions encountered. These influences will force the human resource manager to focus on sharpening competencies existing within the organization, consolidating competencies so that only those currently required by the organization are retained, adding new competencies, or replacing existing competencies so that the organization can move to a new domain activity. The emphasis on human resource processes such as recruitment and termination, training and development, and evaluation, reward, and retention for purposes of development and maintenance of the competencies needed to implement strategic responses to decline will vary according to the nature of the environmental conditions encountered.
