While foreign policy as well as economic, ideological and purely humanitarian considerations all continue to play a role in economic relations between the CMEA countries and the Third World, a shift in the relative weights of these various aspects has become discernible in recent years. What conclusions can be drawn as to the future behaviour of the CMEA countries towards the developing countries?  相似文献

Since the widening of the fluctuation bands in the European Monetary System in 1993 the previous core countries have pursued a “D-Mark shadowing”. The characteristic feature of this shadowing is the participating countries' willingness to voluntarily return to, and maintain, the old exchange rate parities. Our author analyses this process and its consequences for the planned monetary union.  相似文献

So far relatively little is known about the situation of Ph.D. students in media and communication research. The main purpose of this study is, therefore, to shed light on the employment and working conditions for young scholars on their way to their doctoral degrees. We conducted a survey of 281 Ph.D. students in Germany, Switzerland and Austria. The results show that, on the one hand, young scholars are intrinsically highly motivated to do their jobs. On the other hand, they perceive an academic career as a very uncertain venture with many obstacles. Furthermore, several types of Ph.D. students can be distinguished: idealists, careerists and waverers. It is shown that only the idealists conform to the concept of a productive and interested scholar. The results are discussed in terms of their importance for the future development of the field.  相似文献

The present study analyses firm heterogeneity and sector‐specific technology. The theoretical model stands on the assumption of maximizing the return on capital and overcomes problems involved in simple profit maximization. The results show that a random parameter model with sector dummies and heteroscedasticity is the most appropriate model specification for distinguishing firm‐level and sector‐level efficiency and heterogeneity. The heterogeneity among firms as well as among sectors was found to be an important characteristic in Czech food processing. This holds for production technology as well as for technical efficiency. Moreover, the decomposition of total variance shows that intrasectoral differences in technologies are much more pronounced than the intersectoral differences. The differences in intrasector heterogeneity also suggest that the food processing industry will be subject to accelerated structural change in the coming years. Moreover, we found that on average the companies highly exploit their production possibilities. However, some companies cannot keep pace with competitors. Because leapfrogging does not appear to be present in selected industries (except for Milling), structural change is expected to occur in such a way that the most successful companies will strengthen their position.  相似文献

We study behavior in the race game with the aim of assessing whether teams can create synergies. The race game has the advantage that the optimal strategy depends neither on beliefs about other players nor on distributional or efficiency concerns. Our results reveal that teams not only outperform individuals but that they can also beat the “truth-wins” benchmark. In particular, varying the length of the race game we find that the team advantage increases with the complexity of the game.  相似文献

We propose two methods to choose the variables to be used in the estimation of the structural parameters of a singular DSGE model. The first selects the vector of observables that optimizes parameter identification; the second selects the vector that minimizes the informational discrepancy between the singular and non‐singular model. An application to a standard model is discussed and the estimation properties of different setups compared. Practical suggestions for applied researchers are provided.

In light of the shortcomings of the Stability and Growth Pact, there has been a recognition that a surveillance framework is needed which goes beyond fiscal issues to cover wider macroeconomic factors. The question arises whether the surveillance and connected reform criteria should be applied symmetrically, to all members of the eurozone, or whether they should specifically target countries with current account deficits.  相似文献
