Sources of Bank Interest Rate Risk

We investigate bank stocks'sensitivity to changes in interest rates and the factors affecting this sensitivity. We focus on whether the exposure of commercial banks to interest rate risk is conditioned on certain balance sheet and income statement ratios. We find a significantly negative relation between bank stock returns and changes in interest rates over the period 1991–1996. We also find that bank characteristics measured from basic financial statement information explain bank stocks'sensitivity to interest rate changes. These results suggest that bank managers, analysts, and regulators can use this information to assess the relative risk exposure of banks.     

The effectiveness of different mechanisms for integrating marketing and R&D

The integration of marketing and R&D is a major concern for companies that want to improve their new product performance (NPP). For this integration, companies are using mechanisms such as physical proximity, cross-functional teams, and job rotation. This study examines the effectiveness of these mechanisms by developing a model that distinguishes between indirect effects of mechanisms on NPP (i.e., through a higher level of integration) and direct effects. The model is tested with data collected from 148 pharmaceutical companies. We were able to measure and compare the effectiveness of seven different integration mechanisms, which produced insights that are interesting and relevant for theory as well as practice.
We found that housing marketing and R&D closer to each other and using an influential cross-functional phase review board are the most effective mechanisms to foster integration. Equal remuneration and career opportunities for marketing and R&D and cross-functional teams are somewhat less effective, whereas personnel movement and informal social group events contribute little. ICT appears to be a very effective tool for enhancing NPP. ICT not only fosters integration between marketing and R&D, but it also has an independent direct positive effect on NPP. Through ICT the day-to-day communication between the different parties in the companies becomes much easier, and we think that this fosters the knowledge creation process within marketing and R&D. For cross-functional phase review boards we found a negative direct effect on NPP. Notwithstanding its strong positive effect on integration, a price is paid in terms of NPP. This may be related to the amount of formalization and complexity accompanying this mechanism.     

Initial Margin Requirements, Volatility, and the Individual Investor: Insights from Japan

Initial margin requirements represent: (1) a cost impediment to the wealth constrained investor and (2) a potential way of mitigating excessive volatility. However, prior empirical research finds that margins are not an effective tool in reducing volatility. We consider the possibility that margins primarily affect certain stocks and investors. Specifically, we test whether margins affect individuals who, as a group, we believe to be the investors most affected when margin requirements change. Our initial empirical tests, however, do not support this contention.     

Information Disclosure to Employees and Rational Expectations: a Game-Theoretical Perspective: a Comment

In this comment we identify the key features of the Frantz and Walker (1997) game theoretic model that drive the non-disclosure equilibrium result in their paper. We argue that, although technically correct, their model fails to capture certain aspects of real-world wage bargaining that will be important in determining optimal disclosure strategies in practice. However, Frantz and Walker's paper illustrates the potential of analytical techniques to contribute to the employee disclosure debate.     

Futures and forward price differential and the effect of marking‐to‐market: Australian evidence

The objective of this paper is to examine the effects of marking‐to‐market of futures contracts on the price differential between futures and forward contracts based on the predictions of the Cox, Ingersoll and Ross (1981) (CIR) model. Cox et al ., (1981) derive a series of propositions with respect to the relationship between futures and forward prices and a set of testable implications. These are tested empirically in this paper using Australian data from November 1991 to June 1997. The results provide evidence of the presence of significant futures and forward price differences, where the futures price is consistently below the forward price. Only partial support is found for the Cox et al ., (1981) propositions, implying that the effect of marking‐to‐market is not able to fully account for the price differential. Therefore, it is not possible to rule out the influence of other institutional factors on the futures‐forward price difference.

Multiple regimes and cross-country growth behaviour

This paper provides some new evidence on the behaviour of cross-country growth rates. We reject the linear model commonly used to study cross-country growth behaviour in favour of a multiple regime alternative in which different economies obey different linear models when grouped according to initial conditions. Further, the marginal product of capital is shown to vary with the level of economic development. These results are consistent with growth models which exhibit multiple steady states. Our results call into question inferences that have been made in favour of the convergence hypothesis and further suggest that the explanatory power of the Solow growth model may be enhanced with a theory of aggregate production function differences.
