The academic literature on the determination of risk-minimizing hedge ratios has apparently ignored the potential impact that the pricing strategies adopted by the grain elevators may have on the futures-cash price transmission, and therefore on the determination of the correct hedge ratio. This paper addresses this problem from a theoretical perspective, and then develops a model that is applied to the soybean market in Chatham, Ontario.
La littérature académique concernant la détermination des ratios de couverture à terme minimisant le risque a apparemment ignoré l'impact potential des stratégies des faiseurs de prix sur un marché sur la relation entre les prix spot et les prix à terme. II est possible que de ce fait ces stratégies influencent également la détermination du vrai ratio de couverture. Ce papier traite ce problème d'un point de vue théorique, puis vérifie ces résultats en les appliquant au cas du marché du soja à Chatham, Ontario.  相似文献

A typology of a class of service systems is proposed. The typology links strategic operational objectives to the decision to de-couple work between the front and back offices of a service system. Four specific ideal types of a strategy/de-coupling mix are described; each of which has distinct operational, marketing and human resource ramifications. A type that has had significant representation in traditional literature is the “Cost Leader” type, where back-office activities are de-coupled from the front office for the purpose of lowering costs. Another traditional type representative of the craftsman legacy is the “Personal Service” type, which retains back-office tasks in the front office to pursue non-cost-oriented strategic goals. Theoretical and empirical evidence is also given for two non-traditional types: the “Kiosk” type, where all tasks remain in the front office to achieve lower costs, and the “Focused Professional” type, which de-couples front- and back-office activities to enable front-office workers to provide higher service, rather than to reduce costs. Empirically, retail bank lending systems are analyzed to support the typology.  相似文献

Studying a large sample of publicly available data on failures to deliver, we find that stocks reaching threshold levels of failures become significantly overvalued. Where short sale constraints are especially binding, we report extreme overpricing and subsequent reversals. These findings support the overvaluation hypothesis, although the mispricing is likely to be difficult to arbitrage because of extreme shorting costs. In addition, threshold stocks with low short interest become more overvalued than threshold stocks with high short interest. This suggests that the level of short interest reflects supply‐side effects when the examination conditions on the difficulty of borrowing shares.  相似文献

This paper investigates the impact of complementarity reforms on growth and how it depends on GDP per capita. Based on reform data for six policy areas compiled from various sources during the period 1994–2006 for over 100 countries, we compute composite indicators of reform level and complementarity. We provide qualitative justification for the existence of pair-wise complementarities among policy areas. We then use cross-section and panel data estimates to test the effect of reform level and complementarity on GDP per capita growth. We found reforms to be positively related and their dispersion (or the inverse of complementarity) negatively related to growth, controlling for initial conditions, monetary stability and other structural and institutional variables, as well as endogeneity of reform level and complementarity. We show that the effect of policy complementarity is a stronger condition for sustainable growth in developing than in advanced countries, to conclude that complementary reforms are not a ‘luxury’ for developing countries.  相似文献

This work analyzes the relationships between perceived value, satisfaction and future intentions among users of a public sport service who experience a price increase in the service they receive. A self-administered survey provides data from two samples (before and after the service price increase). After confirming the reliability and validity of the measures, hierarchical multiple regression provides the means for analyzing the data. The results show that the increase in the service price worsens the perception of service performance. As expected, satisfaction, perceived value and future intentions decrease following an increase in the service price. Perceived value also serves as a more effective predictor of future intentions than satisfaction. Finally, price increase has a low direct effect on predicting future intentions of sport users.  相似文献

We model strategic interaction in a differentiated input market as a game among two suppliers and n retailers. Each one of the upstream firms chooses the specification of the input which it will offer.Then, retailers choose their type from a continuum of possibilities. The decisions made in these two first stages affect the degree of compatibility between each retailer's ideal input specification and that of the inputs offered by the two upstream firms. In a third stage, upstream firms compete setting input prices. Equilibrium may be of the two-vendor policy or of the technological monopoly type.  相似文献

Based on studies of idiosyncratic volatility developed in the recent literature, this study analyzes its relation with expected returns through the breakdown of idiosyncratic volatility in the Brazilian stock market and presents evidence of the importance of expected idiosyncratic volatility for asset pricing. We study the impact of the expected and unexpected components of idiosyncratic volatility on the returns of shares listed on the BOVESPA between 2004 and 2011. The results show a strong positive and significant relation between expected idiosyncratic volatility and returns. This evidence is highlighted when we use unexpected idiosyncratic volatility to control for unexpected returns. Additional robustness tests, controlling for size and momentum effects, also have positive and significant coefficients, corroborating previous findings.  相似文献

An original model is put forward in this article to explain and consider the behavior of some of the most important public services in Spain. The cost function approach and the input distance function approach are used to estimate the existence of overcapitalization as a result of rate of return regulation. The results show that overcapitalization generated by this regulation is too significant not to be taken into account.  相似文献
