Marginal distributions of sequential and generalized order statistics

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. Key words:Order statistics; Generalized order statistics; Sequential order statistics; Record values; Distribution theory; Meijers G-function; Recurrence relations; Reliability properties.     

Policy Discrimination with and without Interpersonal Comparisons of Utility

Can the Pareto criterion guide policymakers who do not know the true model of the economy? If policymakers specify ex ante preferences for agents, then Pareto improvements from a distorted status quo are usually possible, and with more commodities than states, one can implement almost every Pareto optimum. Unlike the standard second welfare theorem, planners cannot dictate allocations: agents must trade. Unfortunately ex ante preferences impose interpersonal comparisons. If policymakers merely aim to maximize some social welfare function then optimal policies form an open set; hence small changes in the environment do not necessitate any policy response. Planners with symmetric information about agents can sometimes intervene without making interpersonal comparisons.     

Strategies as states

We define rationality and equilibrium when states specify agents’ actions and agents have arbitrary partitions over these states. Although some suggest that this natural modeling step leads to paradox, we show that Bayesian equilibrium is well defined and puzzles can be circumvented. The main problem arises when player j's partition informs j of i's move and i knows j's strategy. Then i's inference about j's move will vary with i's own move, and i may consequently play a dominated action. Plausible conditions on partitions rule out these scenarios. Equilibria exist under the same conditions, and more generally ε equilibria usually exist.     

German managers'' attitudes towards Anglo-American accounting: Results from an empirical study on global accounting harmonization

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.     

Kfz-Steuer für Pkw: Hubraum lässt sich doch ersetzen!

In Germany the car tax is derived from the cylinder capacity. Since 2009 the amount of carbon emissions serves as an additional criterion. Taking recent developments into account, cylinder capacity can no longer be justified as a reasonable tax basis. Instead I propose a progressive tax based solely on carbon emissions to achieve much more appropriate results.     

Trade and the Environment: The Role of Firm Heterogeneity

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.
