The aim of this paper is to contribute to the vivid political discussion on the consequences of the Russian agricultural import ban on the German export market by quantifying export losses that German agri-food exporters encountered on the Russian market due to the agricultural import ban of 2014. A gravity-type approach is used to measure the sanction effect in a panel of German agri-food exports covering the period from January 1999 to June 2018. The ban effect is disentangled from a sequence of different geopolitically- and economically driven episodes. Once macroeconomic developments of the Russian economy as well as individual stages of decreasing trade cooperation in the preban period are accounted for, the import ban reduced German agri-food exports significantly but was not the major cause. Therefore, a simple elimination of the ban will not be enough to restore trade to the presanctions level.  相似文献

The quality endeavors of an organization, like other enterprise activities, must be oriented towards the economic principles. This approach gives a way to many organizations to question the extent to which the quality management contributes for the overall business success and to pin point the areas where particularly a high value or performance can be created in order to attain the maximum possible economic benefits out of quality management systems. Without including the answer of this question in the decision making process, the resources can not be allocated optimally for the quality purpose. Quality management activities create variety of effects that indirectly contributes towards the economic success and thus increase the company and stakeholder value. A closer look at the quality management philosophy reveals eight major principles namely: customer focus, leadership, involvement of people, process approach, system approach to management, continual improvement, factual approach to decision making, mutually beneficial supplier relationships. These eight principles lead the efforts in the domain of quality management to project a positive impact on the company. For an understanding of response relationships, it is necessary to consider in detail the indicators along the response relationships. They provide helpful clues and give an insight into the complex mechanisms of action of the quality approaches on the path to the company's success. The following illustration depicts how the quality based activities generate the value to enhance the performance and a variety of indicators reflects how they indirectly add value to an organization and hence contribute to its economic success.  相似文献

Given the growing importance of cohesion policy within the European Union (EU) during the last two decades, public and scientific interest in the role of EU policies for regional disparities has risen continuously. Recent empirical studies on the impacts of the Common Agricultural Policy (CAP) on economic cohesion have been strikingly diverse in their principal findings. Whereas some studies suggest positive overall effects on economic cohesion, others stress exactly the opposite. One major reason for the ambiguous results is that a single agreed-upon measure of economic cohesion is lacking. We propose a concept that distinguishes between two dimensions of policy impacts on economic cohesion: (i) the redistributive impact at a defined period of time and (ii) the change of the redistributive impact over time. The first dimension addresses the question whether a policy makes the distribution of a target variable, e.g., income, more equal or unequal at one point of time. The second dimension covers the impact of the policy on the disparity of the same variable over time, i.e., the impact on convergence. An empirical illustration of the concept for 13 NUTS 1 regions in Germany over the period 1991–2009 reveals that the two policy impacts of the CAP are partly contradictory for the two dimensions. It is shown that the CAP fosters economic cohesion by reducing regional disparities in each individual year. With regard to redistributive impacts over time, we find that CAP transfers leave income convergence largely unaffected for society as a whole. Within the agricultural sector, it leads to a convergence of receipts per farm whereas it induces a divergence of farm receipts per hectare.  相似文献

In the wake of the global financial crisis, several macroeconomic contributions have highlighted the risks of excessive credit expansion. In particular, too much finance can have a negative impact on growth. We examine the microeconomic foundations of this argument, positing a non-monotonic relationship between leverage and firm-level productivity growth in the spirit of the trade-off theory of capital structure. A threshold regression model estimated on a sample of Central and Eastern European countries confirms that TFP growth increases with leverage until the latter reaches a critical threshold beyond which leverage lowers TFP growth. This estimate can provide guidance to firms and policy makers on identifying “excessive” leverage. We find similar non-monotonic relationships between leverage and proxies for firm value. Our results are a first step in bridging the gap between the literature on optimal capital structure and the wider macro literature on the finance-growth nexus.  相似文献

We present a new approach for the economic analysis of countries, which we apply to the case of the Netherlands. Our study is based on a novel way to quantify exported products’ complexity and countries’ fitness which has been recently introduced in the literature. Adopting a framework in which products are clustered in sectors, we compare the different branches of the export of the Netherlands, taking into account the time evolution of their volumes, complexities and competitivenesses in the years 1995–2010. The High Tech and Life Sciences sectors share high quality products but low competitiveness; the opposite is true for Horticulture and Energy. We analyze in detail the Chemicals sector, finding a declining global complexity which is mostly driven by a shift towards products of lower quality. A growth forecast is also provided. In light of our results we suggest a differentiation in policy between the country’s self-defined industrial sectors.  相似文献

Identity, morals, and taboos: beliefs as assets   总被引:1,自引:0,他引:1  
We develop a theory of moral behavior, individual and collective, based on a general model of identity in which people care about “who they are” and infer their own values from past choices. The model sheds light on many empirical puzzles inconsistent with earlier approaches. Identity investments respond nonmonotonically to acts or threats, and taboos on mere thoughts arise to protect beliefs about the “priceless” value of certain social assets. High endowments trigger escalating commitment and a treadmill effect, while competing identities can cause dysfunctional capital destruction. Social interactions induce both social and antisocial norms of contribution, sustained by respectively shunning free riders or do-gooders.  相似文献

Simple sequencing problems with interdependent costs   总被引:1,自引:0,他引:1  
In this paper we analyze simple sequencing problems under incomplete information and interdependent costs. We prove the necessity of concave cost function for implementability of such problems. Implementability means that one can achieve aggregate cost minimization in ex-post equilibrium. We also show that simple sequencing problems are implementable if and only if the mechanism is a ‘generalized VCG mechanism.’ We then consider first best implementability, that is implementability with budget balancing transfer. We prove that for implementable n agent simple sequencing problems, with polynomial cost function of order (n−2) or less, one can achieve first best implementability. Finally, for the class of implementable simple sequencing problems with “sufficiently well behaved” cost function, this is the only first best class.  相似文献
