Export entry and exit by German firms 总被引:4,自引:1,他引:3
Export Entry and Exit by German Firms. — While exports have played an important role in German business cycles, little is
known about the export supply response of German firms. This paper presents a dynamic model of the export decision by a profit-maximizing
firm. Using a panel of German manufacturing plants, we test for the role of plant characteristics and sunk costs in the entry
decision. We find evidence for substantial sunk costs: exporting today by a plant increases the probability by 50 percent
that the plant will export tomorrow. This advantage depreciates quickly, falling by two-thirds in a year. The authors also
find evidence that plant success, as measured by size and productivity, increases the likelihood of exporting. 相似文献

The paper examines the main issues surrounding distributional effects in the domains of natural resource management and land policies, agricultural technology and research policies, agricultural market and trade policies, and consumer‐oriented policies, including standards, subsidies, and labeling. Agriculture is drifting into an ever more drastic bifurcation at a global level and within many countries. Correcting that bifurcation will require large investments in rural areas and rural people, in institutions, and in information and biological technologies accessible by the poor in the world's smallholder sector. Large and growing national and international inequalities related to agriculture and rural areas threaten peace, growth, and sustainable development. 相似文献

While the role of exports in promoting growth in general, and productivity in particular, has been investigated empirically using aggregate data for countries and industries for a long time, only recently have comprehensive longitudinal data at the firm level been used to look at the extent and causes of productivity differentials between exporters and their counterparts which sell on the domestic market only. This paper surveys the empirical strategies applied, and the results produced, in 54 microeconometric studies with data from 34 countries that were published between 1995 and 2006. Details aside, exporters are found to be more productive than non‐exporters, and the more productive firms self‐select into export markets, while exporting does not necessarily improve productivity. 相似文献

Using representative individual-level data from the first round of the European Social Survey fielded in 2002/03, this article provides an empirical analysis of unionisation in 18 countries of the EU. We show that union density varies considerably in Europe, ranging from 84 per cent in Denmark to 11 per cent in Portugal. Estimating identical models for each country, we find that individuals’ probability of union membership is significantly affected by their personal characteristics, their attitudes and the characteristics of their workplace, whereas social factors seem to play a minor role. The presence of a union at the workplace and employees’ attitudes concerning strong unions are the two variables most strongly associated with unionisation. 相似文献

The paper analyzes the functional relationship between profitability and market share for type of businesses in the PIMS data base. Although a linear relationship has been imposed in other studies, our result shows that empirically it seems a poor representation of the data. In addition, three observations seem to be most evident. First, small-share businesses were not per se less successful than larger business units. In the service market and the market for raw or semi-finished materials small-share businesses were just as profitable or even more profitable than larger business units. Second, some businesses were ‘stuck in the middle’, which was most evident in the service market but also in the retail and wholesale markets. Third, very large-share businesses were often less profitable. A critical market share was identified as between 65 and 70 percent. Beyond that level the ROI decreased. 相似文献

Experimental studies of search behavior suggest that individuals stop searching earlier than the optimal, risk-neutral stopping rule predicts. Two different classes of decision rules could generate this behavior: rules that are optimal conditional on utility functions departing from risk neutrality, or heuristics derived from limited cognitive processing capacities and satisficing. To discriminate between these possibilities, we conducted an experiment that consists of a search task as well as a lottery task designed to elicit utility functions. We find that search heuristics are not related to measures of risk aversion, but to measures of loss aversion. 相似文献

Due to large public deficits in the past, many German states face high interest payments in their budgets today. Therefore, a restructuring of this outstanding debt will be a major topic in forthcoming negotiations on the future design of the fiscal equalisation scheme. This article presents some proposals that are currently being discussed and calculates their redistributional effects between the federal government and the states. It is shown that all models would lead to a significantly higher burden for the federal budget. The only way to afford this is either to increase the value added tax rates or to keep the so-called solidarity surcharge that was originally introduced to finance transfers to East Germany. 相似文献

The aim of this work is to advocate the use of multifractional Brownian motion (mBm) as a relevant model in financial mathematics. mBm is an extension of fractional Brownian motion where the Hurst parameter is allowed to vary in time. This enables the possibility to accommodate for varying local regularity, and to decouple it from long‐range dependence properties. While we believe that mBm is potentially useful in a variety of applications in finance, we focus here on a multifractional stochastic volatility Hull & White model that is an extension of the model studied in Comte and Renault. Using the stochastic calculus with respect to mBm developed in Lebovits and Lévy Véhel, we solve the corresponding stochastic differential equations. Since the solutions are of course not explicit, we take advantage of recently developed numerical techniques, namely functional quantization‐based cubature methods, to get accurate approximations. This allows us to test the behavior of our model (as well as the one in Comte and Renault) with respect to its parameters, and in particular its ability to explain some features of the implied volatility surface. An advantage of our model is that it is able both to fit smiles at different maturities, and to take volatility persistence into account in a more precise way than Comte and Renault. 相似文献

This study is based on the case of BMW, and aims to improve the determination of perceived consumer satisfaction in the automotive industry by transferring existing knowledge from the health care sector. A literature analysis of the health care sector and the automotive industry was conducted to identify the common concepts of determining satisfaction. These were the service encounter, situational factors, and sociodemographics. The practical application was tested by analyzing a contemporary survey from BMW. Based on the findings, managers responsible for customer satisfaction in after-sales services in the automotive industry could improve measurement of customer satisfaction. 相似文献
