In this paper, effects on the measured abnormal performance of test portfolios are compared against market proxies having the same or different rebalancing policies. Results show that the common practice of comparing buy-and-hold test portfolios with equally weighted market proxies produces lower Jensen [ 7 ] alphas and lower alpha t-values. Comparing buy-and-hold test portfolios with value-weighted market proxies produces higher portfolio betas and alphas, but lower alpha t-values. Finally, comparing buy-and-hold test portfolios with buy-and-hold market proxies produces the most powerful tests of abnormal performance. 相似文献

Analysis of the German response to the euro crisis has been framed around a narrative of the relationship between domestic sacrifice and hegemony and sustains an assumption that the German commitment to the euro is proven. Such analysis downplays the importance of the banking crisis in Germany in explaining the decision-making of the German government around the euro-zone debt crisis. Giving German interests in relation to the German banking crisis analytical weight can explain both the positions taken by the German government and their consequences for the underlying structural problems the euro-zone faces as a monetary union. Since the outcomes of German policy have advanced German interests, German handling of the euro-zone crisis cannot sustain a claim that Germany has demonstrated its commitment to the euro. 相似文献

The term 'IT paradox' has been widely used to describe the apparent failure of much economic research to discover significant productivity gains associated with IT investment. In part this has been ascribed to measurement problems associated with both IT inputs and with outputs in IT-intensive industries. The current paper seeks to circumvent these difficulties by taking the ATM as a clearly defined embodied IT application and then using anaugmented production function approach to isolate its productivity effectsacross a sample of UK building societies, over the period of the ATM'sdiffusion. The paper finds no support for the 'IT paradox' and reports large robust and statistically significant productivity gains associated with ATM introduction. 相似文献

The gap in total factor productivity in sawmills and wood preservation between the US and Canada generally increased from 1958 to 2005. The present paper examines the effects of the various phases of the softwood lumber dispute, including relatively free trade, Canadian export taxes, and low and high countervailing duties, on this productivity gap. Exogenous control variables include US housing demand, the exchange rate, softwood lumber prices, and ratios of capital and nonproduction labor to labor. The effects of phases of the dispute on US imports from Canada are also examined. 相似文献
