This paper examines whether there is a discrepancy in estimating the elasticity of intertemporal substitution using food consumption instead of nondurable consumption data. We show that a discrepancy exists and that the discrepancy increases as nondurable consumption increases.  相似文献

This paper analyzes the effects of cross-border mergers and acquisitions on innovation activities in target firms. The empirical analysis is based on survey and ownership data for a large sample of small- and medium-sized German firms. After controlling for endogeneity and selection bias, we find that foreign acquisitions have a large negative impact on the propensity to perform innovation activities and a negative impact on average R&D expenditures in innovative firms. Furthermore, innovation output, measured as product and process innovations, and the share of sales from product innovations, is not significantly affected by a foreign acquisition for a given amount of innovation efforts. Hence, the estimation results do not provide any evidence of significant technology transfer through foreign acquisitions in form of a higher innovation success.  相似文献

Since the Health Care Competition Act (Gesetz zur Stärkung des Wettbewerbs in der Gesetzlichen Krankenversicherung) came into effect on 1st April 2007, a significant consolidation process within the statutory health insurance (GKV) in Germany has begun, emphasizing the need for regulated merger control. The conflicts that currently exist between social law and competition law are limiting factors in this. This article examines in detail the existing conflicts and seeks possible solutions for regulated merger control in the field of the GKV that conform both to the regulations in social law and to the regulations regarding competition. On the basis of the Herfindahl-Hirschman Index, a solution scenario is developed which would eliminate the existing areas of conflict in GKV merger control almost without exception and which could even be applied in the field of private health insurance (PKV) in the case of an ongoing assimilation of GKV and PKV.  相似文献

Ecolabelling is an increasingly important tool used in the promotion of sustainable forestry and fishery products around the world. Whether the consumer is actually paying a price premium for ecolabelled products is of fundamental importance as it indicates a return on the investment of sustainable practices, providing an incentive for producers to undertake such practices. This article seeks to address the question of whether or not an actual premium is being paid by consumers for ecolabelled seafood by conducting a hedonic analysis of Marine Stewardship Council (MSC)‐certified frozen processed Alaska pollock products in the London metropolitan area in the UK market using scanner data. Regression results show a statistically significant premium of 14.2%. This implies the presence of market differentiation for sustainable seafood and the potential of the MSC’s fisheries certification programme to generate market incentives for sustainable fisheries practices.  相似文献

We employ a model of n heterogenous profit-maximizing clubs to analyze the impact of revenue sharing in professional sports leagues on competitive balance. Revenues of each club depend on absolute quality, relative quality and on competitive balance itself so that our model captures much of the preceding literature as special cases. We show that revenue sharing always increases competitive balance if clubs differ only with respect to the impact of absolute quality on revenues. On the contrary, revenue sharing reduces competitive balance if only clubs' relative qualities play a role for revenues or if only two teams are considered.  相似文献

This paper empirically studies the relationship between the governance mechanisms and the market valuation of publicly listed firms in China. The authors construct measures for corporate governance mechanisms and measures of market valuation for all publicly listed firms on the two stock markets in China by using data from the firm’s annual reports. They then investigate how the market-valuation variables are affected by the corporate governance variables while controlling for a number of factors commonly considered in market valuation analysis. A corporate governance index is also constructed to summarize the information contained in the corporate governance variables. The index is found to have statistically and economically significant effects on market valuation. The analysis indicates that investors pay a significant premium for well-governed firms in China, benefiting firms that improve their governance mechanisms.

A model of option exchange design is proposed and tested. The model allows investors to choose among several exchange‐traded options based on a trade‐off between standardization costs and liquidity/transaction costs. It employs a spatial economics approach to provide results for the existence of markets for particular option contracts on the exchange, a comparison of exchange design by a social planner and a profit‐maximizing monopolist (corresponding to the idea that most derivatives exchanges centralize the design and creation of option contracts), and comparative statics that can potentially aid decision makers in the design of option exchanges. In the empirical work, open interest is analyzed for Chicago Board Options Exchange (CBOE) options on the stocks in the S&P 100 index. In accordance with the model's predictions, open interest forms a previously undocumented seesaw pattern across strike prices, clustering around certain strike prices, and dropping off for the adjacent strike prices. © 2006 Wiley Periodicals, Inc.

This study investigates whether models of forward‐looking behavior explain the observed patterns of heavy drinking and smoking of men in late middle age in the Health and Retirement Study better than myopic models. We develop and estimate a sequence of nested models that differ by their degree of forward‐looking behavior. Our empirical findings suggest that forward looking models fit the data better than myopic models. These models also dominate other behavioral models based on out‐of‐sample predictions using data of men aged 70 and over. Myopic models predict rates of smoking for old individuals, which are significantly larger than those found in the data on elderly men.  相似文献
