We conduct a unique test of adverse selection in the equity issuance process. While common stock is the dominant means of payment in bank mergers, stock acquisition agreements provide target shareholders with varying degrees of protection against adverse price movements in the bidder's stock between the time of the merger agreement and the time of merger completion. We show that it is the degree of protection against adverse price changes and not the percent of stock offered in a bank merger that explains bidder merger announcement abnormal returns. This result is difficult to explain outside of an adverse selection framework.  相似文献

This paper develops a two-region two-sector endogenous growth model with a dual labour market based on efficiency wages. Growth is driven by research done in the (high-tech) tradeables sector. The follower region tends to catch up in terms of labour productivity with the leader region. Differences in unemployment compensation systems can lead to relative convergence, i.e., a steady state with the backward region lagging behind the leader region. The reason for this is that high social welfare compensations generate high unemployment and reduce the amount of labour employed for R&D purposes.  相似文献

This paper provides industry-of-origin comparative estimates of real output and labour productivity in the Indonesian and Australian manufacturing sectors. It makes binary comparisons for the benchmark year 1987, and extrapolates the 1987 benchmark backward and forward using national time series, to derive comparisons for the years 1975–90. Expressed in ‘purchasing power parities’ (PPPs), the gross value of output and value added in Indonesian manufacturing in 1987 was 40% and 34% of the respective Australian levels. In 1987 the Indonesian manufacturing price level was 74% of the Australian level, and Indonesian manufacturing labour productivity was 16% of that in Australia. 1975 to 1990 was a period of catch-up. The Indonesian manufacturing price level declined from 105% to 60% of the Australian level, while labour productivity increased from 12% to 17% of the Australian level. The catch-up was greater from the early 1980s onwards.  相似文献

The etiology of many human diseases is complex and very likely involves a combination of genetic and environmental risk factors. A popular strategy to detect genetic risk factors is to perform a systematic screening of the genome searching for linkage. The power of such and approach depends very much on the unknown characteristics of the genetic factors and the main difficulty is to establish a good trade-off between false positives and false negatives. Besides, a precise localisation of the risk factor will generally not be obtained. The set up of a candidate gene stratery is necessary to go further in genetic factor identification. It is likely that for multicfactorioal diseases the only genetic risk factors that can be detected are those with fairly strong effect. Even in that case, it is important to design strategies which increase the power of detection and provide for a better evaluation of the associated risks.  相似文献

In this study, we examine short selling of NASDAQ stocks and observe that more information about future returns is contained in small short sales than in medium-sized and large short sales, thus supporting the idea that NASDAQ short sellers stealth trade. These results are robust to different subsamples of stocks with and without tradable options and stocks that are more likely to face binding borrowing constraints. Further, these findings are contrary to the results in Boehmer, Jones, and Zhang (2008) who find that large NYSE short sales contain the most information. Combined, our study supports the idea that NASDAQ's bid test is less restricting than the NYSE's uptick rule and therefore attenuates the likelihood of stealth trading (Diether, Lee, & Werner, 2009a).  相似文献
