A re-examination of the forward exchange rate unbiasedness hypothesis

A Re-Examination of the Forward Exchange Rate Unbiasedness Hypothesis. — This paper applies the Phillips and Hansen estimation and inference procedures to re-examine the hypothesis that the forward exchange rate is an unbiased predictor of the future spot exchange rate. The results indicate that the 90-day forward exchange rate is not an unbiased predictor. However, the 90-day forward and future spot exchange rates are cointegrated. Only for the U.K. pound/U.S. dollar exchange rate is there an error correction representation. Overall, however, the evidence is consistent with the hypothesis that risk-averse agents in the forward foreign exchange market form expectations rationally.     

Global instability in experimental general equilibrium: the Scarf example

Scarf (Int. Econ. Rev. 1 (1960) 157) proposed a model of dynamic adjustment in which the standard tatonnement price adjustment process orbits around, rather than converges to, the competitive equilibrium. Hirota (Int. Econ. Rev. 22 (1981) 461) characterized the price paths. We explore the predictions of Scarf's model in a non-tatonnement experimental double auction. The average transaction prices in each period do follow the path predicted by the Scarf and Hirota models. When the model predicts convergence the data converge; when the model predicts orbits, the data orbit in the direction predicted by the model. Moreover, we observe a weak tendency for prices within a period to follow the path predicted by the model.

Trends in British public investment

British public investment has declined sharply both as a share of GDP and as a share of government spending since the 1970s. Only part of this decline is explained by privatisation, which transferred some public investment to the private sector. More important was the very large and permanent reduction in public house‐building between the mid‐1970s and the early 1980s. Between the late 1980s and the early 1990s, the rate of public investment recovered somewhat, but after that time it declined again, reaching a record low in 1999. The most recent decline in public investment has affected a range of central government programmes, and it has not been significantly offset by investment under the Private Finance Initiative. The government now plans to increase investment spending, although levels look set to remain low by historical standards for some time to come.

基于委托代理论的国际人力资源控制关联性实证研究——以上海地区跨国公司为例

本文主要通过战略思维,确定跨国企业海外经营时的假设性问题,并作为国际人力资源管理研究议题,藉由模型建构与实证研究,得到研究发现,并汇集成研究结论。根据交易成本与委托代理论的假设,跨国企业在海外经营会有市场不完全性与派外人员的委托代理问题,此时采取国际人力资源控制机制是母公司解决这些问题的治理机制。当国际人力资源战略已经选择,应该采用何种国际人力资源控制,以使公司的营运绩效能最大化。
