Corruption perceptions vs. corruption reality

This paper examines the accuracy of corruption perceptions by comparing Indonesian villagers' reported perceptions about corruption in a road-building project in their village with a more objective measure of ‘missing expenditures’ in the project. I find that villagers' reported perceptions do contain real information, and that villagers are sophisticated enough to distinguish between corruption in a particular road project and general corruption in the village. The magnitude of the reported information, however, is small, in part because officials hide corruption where it is hardest for villagers to detect. I also find that there are biases in reported perceptions. The findings illustrate the limitations of relying solely on corruption perceptions, whether in designing anti-corruption policies or in conducting empirical research on corruption.     

Wettbewerb und Regulierung des Bahnmarktes

Die Wettbewerbssituation auf dem deutschen Bahnmarkt ist vielschichtig: Sowohl die verschiedenen Teilsegmente des Bahnmarktes als auch der intermodale Wettbewerb müssen berücksichtigt werden. Dabei besteht die Gefahr, die Wettbewerbsposition des gesamten Eisenbahnverkehrs gegenüber anderen Verkehrstr?gern aus den Augen zu verlieren.     

Fiscal implications of climate change

Climate change is an externality problem—so the challenges that arise in limiting it and dealing with the effects that remain are largely fiscal. The structure of the problem, however, and the uncertainty which surrounds it, make the design of proper policy responses particularly complex. This paper provides a primer on the fiscal implications of climate change, the aim being to provide a (reasonably) quick and comprehensive overview of the main analytical issues and lessons learned.     

FINANCING AND HOUSE PRICES

Recent empirical evidence on the effect of below-market financing on house prices has suffered from estimation and interpretation problems. In this paper, a methodology is developed to solve these problems. Using data for mortgage revenue bonds, the methodology is tested with results indicating that all financing subsidy is capitalized into house prices.     

Information and trade sizes: The case of short sales

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).     

The returns from rent-seeking: campaign contributions, firm subsidies and the Byrd Amendment

Abstract .  This is the first empirical study to examine Congressional support of a new law that distributes antidumping duties to protected firms. Because the law produces a transparent measure of how much each firm was rewarded for its efforts to secure the bill's passage, it provides researchers with a unique opportunity to study the link between the expected financial returns to firms, campaign contributions, and Congressional behaviour. Our results indicate that campaign contributions from beneficiaries increased the likelihood that lawmakers would sponsor the law, while contributions from the law's beneficiaries increased with the rewards they expected to receive.     

美国偏见与亚洲创新

当谈论中国的互联网和移动通信时，我们经常听到中国复制（Copy-to-China）现象。反观亚洲互联网技术的发展，尤其是韩国与日本，西方看待亚洲一直有偏见，甚至亚洲自视也如此。但是亚洲正悄然转变为创新工厂。
