Expressions for marginal distribution functions of sequential order statistics and generalized order statistics are presented without any restrictions imposed on the model parameters. The results are related to the relevation transform, to the distribution of the product of Beta distributed random variables, and to Meijers G-functions. Some selected applications in the areas of moments, conditional distributions, recurrence relations, and reliability properties are shown.

The starting-point of the present paper are systematic differences between the answers of German corporate managers and professors in an empirical study by C&L Deutsche Revision AG (1995) on accounting harmonization. In this study, managers expressed themselves in all questions more positively towards current German accounting and more negatively towards US accounting than professors. The fundamental assumption put forward in this paper is that these differences are due to differences in the economic interests of the two groups. To test this empirically, hypotheses are deduced with regard to the accounting-related interests of the executive managers. The idea behind the hypotheses is that managers' answers to questions in the C&L Industry Study can be explained by structural features of their respective companies. The hypotheses are tested using multiple regression analysis. The results of the tests show that managers' answers can, to some extent, be explained by the suggested multiple regression approach. However, the answers to the rather general and abstract question (the preferred balance between the true-and-fair-view and prudence accounting principles) are much better explained than the answers with regard to detailed US-GAAP regulations. We must assume that the managers' attitudes towards concrete US-GAAP, which are directly related to corporate accounting practice, are influenced by a multitude of firm-specific and personal factors. 相似文献

In this paper, we derive a new effect of trade liberalization on the quality of the environment. We show that in the presence of heterogeneous firms, the aggregate volume of emissions is influenced by a reallocation effect resulting from an increase in the relative size of more productive firms. The relative importance of this reallocation effect and the scale effect well‐known from the literature is affected by the emission intensity at the firm level. Domestic emissions decrease as a result of a unilateral tariff reduction if and only if firm‐specific emission intensity decreases strongly with increasing firm productivity. As a result of the induced change in foreign emissions, domestic pollution can increase even if domestic emissions decrease. 相似文献

Sustainability of increasing relevance also for seafood markets. The aim of this contribution is to analyze consumer preferences and their willingness to pay (WTP) for different sustainability claims, and to identify consumer segments according to their WTP. The contingent valuation method was applied to elicit consumers’ WTP in eight European countries. The WTP varies between seven and almost 20%, depending on attribute and country. Three consumer groups become apparent: the largest group without any additional WTP, a smaller group with a moderate additional WTP of plus 17%, and a very small group with an additional WTP of more than 40%. Clear differences between countries are obvious regarding preferences for different sustainability attributes, particularly in the segment with the highest WTP. A fraction of the consumers is willing to pay significantly higher prices for sustainably produced fish from Europe: given that trustful standards are applied and well communicated. 相似文献

We present a model of a risk-averse exporting firm subject to liquidity constraints. We show that preferences and expectations become important for optimum export and hedging decisions. Only firms that have sufficient financial resources can fully materialize gains from trade. 相似文献
