In this paper, we develop a model of technology adoption and economic growth in which households optimally obtain either a concept-based, general education or a skill-specific, vocational education. General education is costly to obtain, but enables workers to operate new production technologies. Firms weigh the cost of adopting and operating new technologies against increased profits and optimally choose the level of adoption. We show that an economy whose policies favor vocational education will grow slower in equilibrium than one that favors general education. More importantly, the gap between their growth rates will increase with the growth rate of available technology. By characterizing the optimal Ramsey education policy we also demonstrate that the optimal subsidy for general education increases with the growth rate of available technology. Our theory suggests that European education policies that favored specialized, vocational education might have worked well, both in terms of growth rates and welfare, during the 1960s and 1970s when available technologies changed slowly. However, in the information age of the 1980s and 1990s when new technologies emerged at a more rapid pace, they might have contributed to an increased growth gap relative to the United States.  相似文献

In the recent past, the automotive supply industry has been facing increasing merger activity. This paper examines the short- and long-term wealth effects of horizontal mergers and acquisitions on acquirers in the automotive supply industry. Based on a sample of 230 takeover announcements between 1981 and 2007, significant positive announcement returns to acquiring companies were determined. While these positive short-term returns to acquirers represent an outstanding attribute of this industry in terms of perceived synergy potential, this study also finds that acquirers are unable to sustain this exceptional position beyond a short-term horizon. A combination of the Fama-French-3-Factor model in calendar time and the control firm approach in event time consistently reveals significant value destruction of about 20% over 3years. In addition, the study determines a significant impact of internationalization, transaction volume, product diversification, and acquirer’s bidding experience on the long-term post-acquisition performance.  相似文献

We consider a robust version of the classic problem of optimal monopoly pricing with incomplete information. In the robust version, the seller faces model uncertainty and only knows that the true demand distribution is in the neighborhood of a given model distribution. We characterize the pricing policies under two distinct decision criteria with multiple priors: (i) maximin utility and (ii) minimax regret. The equilibrium price under either criterion is lower then in the absence of uncertainty. The concern for robustness leads the seller to concede a larger information rent to all buyers with values below the optimal price without uncertainty.  相似文献

This analysis’ goal is to characterise the impact of mid-tier auditors on competition and average supplied audit quality. The major result of our analysis is the following: Auditors’ flexibilities with respect to clients’ complexity determine the offered audit quality levels and thus the average supplied audit quality. Defining a model-endogenous quality measure, we show that for some instances the mid-tier auditor improves average audit quality, but for other instances fails to do so. The result could be of special interest for standard setters, for example, the European Commission, which is currently revising EU audit regulation. Further, the analysis may serve as an instrument to analyse economic consequences of future changes of regulation.  相似文献

This paper presents microeconometric evidence on financing constraints for research and development activities in German small‐ and medium‐sized firms (SME). Special attention is paid to the role of public research and development (R&D) subsidies. For this purpose SMEs in West and East Germany are compared because these regions are very different in their supply of public R&D funding. The empirical evidence suggests that West German SMEs are financially constrained in their R&D activities by both internal and external resources. In East Germany, firms are not sensitive to external constraints, possibly due to high public R&D subsidies. The results show that R&D in East Germany is to a large extent driven by public subsidies and that the usual financial market mechanisms are dysfunctional with respect to R&D in this region.  相似文献

This study tests for underreaction and overreaction in European large cap markets by examining the abnormal returns of those stocks in the EuroStoxx 50 Index following large price increases and decreases. We find that large price increases and declines tend to be followed by average market returns. Thus, our results support the efficient market theory, rather than any of the behaviour finance hypotheses. This insight is contrary to price patterns found in various national markets.  相似文献

In recent years, the continuous structural change in the value chain of modern food production has been characterised by an increasing international division of labour among manufacturing companies. A regional specialisation of primary agricultural production is especially apparent in meat production. Thus, the German–Dutch border area has developed into a region of unprecedented intensive pork production. While The Netherlands specialises in piglet production, the production of fattened pigs continues to grow in northwest Germany. As a result of this increasing transnational value chain development, German imports of Dutch piglets have risen continuously since 2000. However, this structural interweaving of pork production between The Netherlands and Germany has resulted in many new challenges for the cooperation between the various participants and in particular for the administrative authorities in the field of food and feed safety as well as efficient animal disease control. The motivation for this exploratory study stems from the lack of scientific work on this topic to date. The aim of this research is to illustrate the relevance of functioning cross-border cooperation in the food sector, using commodity flow structures and disease spread analysis. Results indicate that cross-border cooperation between authorities during a CSF epidemic can reduce the risk of recurrence and the duration by 50%.  相似文献

This research investigates the moderating role of organizations’ structural context on the performance outcomes of the firm's alignment and adaptability pursuits. It focuses in particular on the role of decision autonomy and shared responsibility, and posits that these structural features exert opposing influences on the effect of alignment and adaptability on performance. Using a sample of more than 200 Canadian‐based firms, this study finds that at higher levels of decision autonomy, the positive relationship between alignment and performance becomes weaker, and the positive relationship between adaptability and performance becomes stronger. Furthermore, at higher levels of shared responsibility, the positive relationship between adaptability and performance strengthens. Thus, the study offers structure‐based explanations for the challenge that organizations face when they attempt to reap the benefits of alignment and adaptability simultaneously.  相似文献
