This paper uses Australian data to analyze takeover bid premiums and long‐term abnormal returns for mergers that occur during wave and non‐wave periods. Findings reveal that bid premiums are slightly lower in wave periods, and bidding firms earn normal post‐takeover returns (relative to a portfolio of firms matched on size and survival) if their bids were made in non‐wave periods. However, bidders who announced their takeover bids during wave periods exhibit significant underperformance. For mergers that took place within waves, there is no difference in bid premiums nor is there a difference in the long‐run returns of bidders involved during the first half and second half of the waves. We find that none of prominent theories of merger waves (managerial, misvaluation, and neoclassical) can fully account for Australian takeover waves and their effects. Instead, our results suggest that Banal‐Estanol et al.'s screening theory of merger activity, by combining the misvaluation and neoclassical theories, may provide a better explanation. 相似文献

The effect of nonheterosexuality on individual income is estimated using 1991–1996 General Social Survey data. Other researchers have concluded that homosexuals earn less than similarly qualified workers, in contrast to the popular perception that homosexuals are more affluent than nonhomosexuals. Using improved statistical techniques, this article finds noticeable earnings effects that go in opposite directions across genders. Nonheterosexual men earn 22% less than heterosexual men, and nonheterosexual women earn 30% more than heterosexual women. These findings, viewed together with previous empirical work on this topic, help narrow the field of theories that can explain the sexual-orientation earnings gaps present in the data. 相似文献

This study applies Geweke [J. Am. Stat. Assoc. 76 (1982) 304] measures of information flow and dependence between Australian individual share futures (ISF) contract and its underlying stock market to investigate whether the price discovery function of futures price has been enhanced after the switch of futures contracts from cash settlement to physical delivery. It is found that the spot market leads the futures market as the futures trading volume is rather small. Further tests suggest that the switch from cash settlement to physical delivery in the ISF contracts has reinforced the information flow from the spot market to the futures market. 相似文献

Survey-based research concerning sexual behaviour almost inevitably confronts the simultaneous problems of misreporting and non-response. These problems lead to disparities among estimates of the number and characteristics of those who engage in same-sex sexual behaviour. This paper proposes a statistical model to consistently estimate the frequency of same-sex sexual behaviour in the presence of non-ignorable misreporting and non-response. The model is fitted using 1991–2000 General Social Survey data. Frequency estimates corrected for simultaneous misreporting and non-response are reported. According to the model, 7.1% of US males and 4.1% of females – 15.8 million individuals – are not exclusively heterosexual. Allowing for misreporting and non-response increases the estimated same-sex frequency by more than four million. The model reveals new patterns between misreporting and non-response probabilities and standard demographic variables such as age and income. 相似文献

The calculation of the hedge ratio, and therefore the effectiveness of the hedge, is dependent upon the correct specification of the relationship between the futures and spot price. Likewise, a forecast of the future spot or futures price is dependent upon the model specification. This article investigates the appropriateness of using a threshold cointegrated model of the natural gas markets as the basis for hedging and forecasting. The findings suggest that the threshold model is more appropriate for longer contract length and that the threshold model does not offer much improvement in hedging or forecasting efficiency. 相似文献

This paper examines the scholarship payback policy embedded in a study abroad program. A full payback policy requires a student to return the whole amount of the scholarship should he fail to achieve a target post-program performance, whereas a partial payback policy requires a payback amount in proportion to the extent of the under-performance. It is found that, the university should adopt a fixed amount scholarship to maximize the average post-program ability. There is also an optimal partial payback policy. 相似文献

A methodological challenge in testing Easterlin's paradox, which states that increasing income fails to boost happiness beyond a satiation point, lies in the determination of this threshold if it exists. In the existing literature, various levels of GDP per capita have been chosen based upon visual inspection of the scatter plots of the data. The estimated income–well‐being gradients are sensitive to the choice of such kink points. We first replicate the results in Stevenson and Wolfers (American Economic Review, Papers and Proceedings 2013; 103 (3): 598–604), then apply the methods proposed in Hansen (Journal of Business and Economic Statistics 2016), which estimate the regression kink model with an unknown threshold, to the data in Stevenson and Wolfers ( 2013 ) to re‐examine the two modified versions of Easterlin's hypothesis. In most cases, we do not find the existence of any kink point. In the few cases where a kink point is detected, the estimated kink point thresholds are different from those chosen in the previous literature. Overall, we find no evidence of a satiation point, which is in support of Stevenson and Wolfers ( 2013 ). Copyright © 2016 John Wiley & Sons, Ltd. 相似文献

This article assumes that because of liquidity constraints, a hedge program will be terminated if the cumulative loss from a futures position exceeds a certain threshold. The constraint leads to a smaller futures position. If the hedger has a quadratic utility function, then the optimal futures position is constant regardless of the parameter values and increases as the spot position or the conventional hedge ratio increases. When the capital allocation is small, the hedger tends to ignore this restriction and chooses a larger position. Consequently, the optimal position may decrease as the capital allocation increases. For a moderate capital allocation, the optimal position increases with an increasing capital allocation. Similar properties are established for exponential utility functions. © 2003 Wiley Periodicals, Inc. Jrl Fut Mark 23:603–613, 2003 相似文献

The purpose of a cultural institute is to improve international relations with other countries by promoting language familiarity and cultural awareness. In addition, cultural institutes can provide additional business opportunities that lead to positive economic side effects such as increases in trade and foreign direct investment (FDI). In this study, gravity models were used to analyse the data for the Goethe Institut (Germany), the Cervantes Institute (Spain) and the Confucius Institute (China) to identify any stylised international patterns of the documented economic effects. The study finds significant positive effects on bilateral trade and FDI outflows for all three programmes, along with two important (i) the effects are stronger for non‐advanced economies and (ii) the effects are substantially larger on FDI than on trade. These results suggest that cultural institutes can be an effective policy tool in promoting FDI outflows, with the strongest effect realised when a home country locates its cultural institutes in host countries with developing economies. Importantly, results also suggest that the Chinese government's approach to extend its soft power through rapid expansion of Confucius Institutes worldwide has not been as successful as the efforts by the German Goethe Institut in increasing trade and FDI. 相似文献
