In this paper we examine the productive performance of a group of three East European carriers and compare it to thirteen of their West European competitors during the period 1977–1990. We first model the multiple output/multiple input technology with a stochastic distance frontier using recently developed semiparametric efficient methods. The endogeneity of multiple outputs is addressed in part by introducing multivariate kernel estimators for the joint distribution of the multiple outputs and potentially correlated firm random effects. We augment estimates from our semiparametric stochastic distance function with nonparametric distance function methods, using linear programming techniques, as well as with extended decomposition methods, based on the Malmquist index number. Both semi- and nonparametric methods indicate significant slack in resource utilization in the East European carriers relative to their Western counterparts, and limited convergence in efficiency or technical change between them. The implications are rather stark for the long run viability of the East European carriers in our sample. 相似文献

This paper uses financial market data to study the effects of deregulation on the expected future profitability of United States cable television system operators. The results suggest that although deregulation has enhanced the profitability of these firms, the effect was not anticipated at the time when the deregulatory legislation was passed. Two possible explanations for the unexpected increase in economic rents accruing to cable system shareholders are offered. 相似文献

We hypothesize debt markets—not equity markets—are the primary influence on “association” metrics studied since Ball and Brown (1968 J Account Res 6:159–178). Debt markets demand high scores on timeliness, conservatism and Lev’s (1989 J Account Res 27(supplement):153–192) R 2, because debt covenants utilize reported numbers. Equity markets do not rate financial reporting consistently with these metrics, because (among other things) they control for the total information incorporated in prices. Single-country studies shed little light on debt versus equity influences, in part because within-country firms operate under a homogeneous reporting regime. International data are consistent with our hypothesis. This is a fundamental issue in accounting. 相似文献

In 2000, the Urban Institute paired African-American and Hispanic testers with whites and sent the pairs to visit lenders in Chicago and Los Angeles, in order to inquire about information on obtaining a home mortgage. In Chicago, African Americans and Hispanics systematically received less information and assistance than comparable whites; while in Los Angeles, the treatment of minority and white testers did not differ statistically from each other. Multivariate analyses for Chicago indicate that large lenders treat minorities more favorably than smaller lenders and that lenders with substantial numbers of applications from African-Americans treat African-Americans more favorably than lenders with predominantly white application pools. 相似文献

Recently, the ethical rather than just the economic resonance of entrepreneurship has attracted attention with researchers
highlighting entrepreneurship and ethics as interwoven processes of value creation and management. Recognising that traditional
normative perspectives on ethics are limited in application in entrepreneurial contexts, this stream of research has theorised
entrepreneurship and ethics as the pragmatic production of useful effects through the alignment of public–private values.
In this article, we critique this view and use Kant’s concept of reflective judgement as discussed in his Critique of the Power of Judgement to theorise ethical entrepreneurial practice as the capacity to routinely break free from current conventions through the
imaginative creation and use of self-legislating maxims. Through an analysis of the narratives of 12 entrepreneurs, we suggest
there are three dimensions to reflective judgement in entrepreneurial contexts: (1) Social Performance; (2) Public Challenge
and; (3) Personal Autonomy. Whilst the entrepreneurs were alive to the importance of commercial return, their narratives demonstrated
further concern for, and commitment to, standards that they rationally and imaginatively felt as being appropriate. In our
discussion, we integrate the findings into existing theoretical categories from entrepreneurship studies to better appreciate
ethics within the context of value creation. 相似文献

Recent work documents large positive abnormal returns when a hedge fund announces activist intentions regarding a publicly listed firm. We show that these returns are largely explained by the ability of activists to force target firms into a takeover. For a comprehensive sample of 13D filings by portfolio investors between 1993 and 2006, announcement returns and long-term abnormal returns are high for targets that are ultimately acquired, but not detectably different from zero for firms that remain independent. Firms targeted by activists are more likely than control firms to get acquired. Finally, activist investors’ portfolios perform poorly during a period in which market wide takeover interest declined. 相似文献

This study illustrates the impact of both spot and option liquidity levels on option prices. Using implied volatility to measure the option price structure, our empirical results reveal that even after controlling for the systematic risk of Duan and Wei ( 2009 ), a clear link remains between option prices and liquidity; with a reduction (increase) in spot (option) liquidity, there is a corresponding increase in the level of the implied volatility curve. The former is consistent with the explanation on hedging costs provided by Cetin, Jarrow, Protter, and Warachka ( 2006 ), whereas the latter is consistent with the “illiquidity premium” hypothesis of Amihud and Mendelson ( 1986a ). This study also shows that the slope of the implied volatility curve can be partially explained by option liquidity. © 2011 Wiley Periodicals, Inc. Jrl Fut Mark 相似文献

Abstract We present a survey of key results from second‐best optimal redistribution theory and their implications for tax‐transfer policy. The core results include the Corlett‐Hague theorem, the Deaton conditions, the production‐efficiency theorem, the Atkinson‐Stiglitz theorem, and the Mirrlees‐Saez characterization of the optimal non‐linear income tax system. These have been augmented in recent years by optimal participation tax rates, the implications of involuntary unemployment, the use of unconventional instruments, such as minimum wages, in‐kind transfer, and workfare, and the optimal taxation of capital income and bequests. 相似文献

This study undertakes firm-level analysis of investment opportunities and free cash flow in an attempt to explain the source of the wealth effect of financial liberalization for 14 emerging countries. We find that the market's responses to stock market liberalization announcements are more favorable for high-growth firms than for low-growth firms, a result that is consistent with the investment opportunities hypothesis. We also demonstrate that firms with high cash flow experience lower announcement-period returns associated with stock market liberalization than do firms with low cash flow. Our findings suggest that the free cash flow hypothesis dominates the corporate governance hypothesis in terms of the net effect of stock market liberalization on a firm's stock returns. We further document similar evidence with regard to banking liberalization. Finally, we demonstrate that stock market liberalization leads to the more efficient allocation of capital. 相似文献
