Pischke and von Wachter (Review of Economics and Statistics 2008; 90 (3): 592–598) find zero earnings returns to compulsory schooling in the basic school track in Germany. We reanalyze their study using a different dataset. In an extension, we use additional instruments which allow estimation of heterogeneous effects for different groups of compliers. We can confirm the previous result and also find zero returns for other compliers in higher track schools. Moreover, we do not find a causal effect of schooling on cognitive skills. This is in line with a potential reason Pischke & von Wachter (2008) give for their result, namely that basic skills are learned earlier in Germany and additional years of schooling are no longer effective.

Why did household debt in Germany not increase after the year 2000? This article offers a supply-side explanation for this deviant debt trajectory by tracing the historical evolution of retail banking in the German political economy. It argues that at the end of the 1990s and in the light of European Monetary Union, profitability issues and banking fragmentation became severe enough to interrupt the path towards credit-based financialisation as prevalent among other capitalist economies. These factors interacted with a traditional lack of tools and incentives for rapid credit expansion, even though they were renegotiated in the processes of financial liberalisation, internationalisation and innovation. By employing historical-qualitative as well as statistical evidence for the argument, the paper’s contribution becomes twofold. First, it introduces and conceptualises retail banking as a focal point in the analysis of national financial systems and their transformation. Second, it complicates the standard accounts of German non-financialisation and reveals the ‘contested’ character of financial reform.  相似文献

This article documents the popularity of five types of trail-based recreation relative to other forms of recreation that tourists frequently participate in on their trips; identifies these trail users’ cross-participation in other outdoor recreation activities; and profiles the travel behaviour, media habits, trip planning behaviour, and demographic and socioeconomic characteristics of day hikers and snowmobilers as two particularly large trail user segments. Findings are based on data from a household telephone survey conducted in Michigan, surrounding states, and Ontario, Canada. Hiking/backpacking was found to be the most popular natural resource-based recreation activity that respondents participated in on pleasure trips taken during the past 12 months; other forms of trail-based recreation were significantly less popular; mountain bikers participated in nature-oriented recreation activities in Michigan at levels that were similar to those of hikers/backpackers; and snowmobiling appeared to be the focus of most pleasure trips on which this activity occurred, in contrast to day hiking, which appeared to be more of an ancillary pursuit.  相似文献
