捷克与中国的贸易存在巨额的赤字。撇开捷克贸易赤字的出口一方,我们来看一下进口。捷克是中国对欧盟进口的门户吗?中国的进口是否被用到了进一步加工领域?文章分析了影响贸易赤字的各个因素,比较了捷克与欧盟15国及波兰、匈牙利和斯洛伐克从中国的进口情况。分析表明,捷克从中国的进口表现出与其他国家非常不同的发展趋势,不仅进口量巨大(占GDP的比重),而且在投资品和进一步加工产品方面有快速的发展。对格鲁伯—劳埃德产业内贸易指数的计算表明,在所有测算国家中中捷贸易的数值最低。该研究验证了一个假设:捷克是中国进入和拓展欧盟市场的一个立足点。  相似文献

In the 1940s and 1950s, institutionalist economists rapidly lost their influence over American economics. In parallel, a new mainstream emerged, and the institutionalists were extremely dissatisfied with the path taken by the economic science. We analyze the opinions and feelings about this context to shed light on the institutionalists’ understanding of the new mainstream economics. We construct a historical account of the institutionalists’ dissatisfaction with post-war economics based on archival material from the personal papers of Allan Gruchy, John Gambs, John Blair, and Clarence Ayres. In the period analyzed, the economists, who would later found the Association for Evolutionary Economics, acted as dissenters rather than institutionalists. In part, this explains the pluralistic path that the association has followed ever since its foundation.  相似文献

The objective of the paper is to determine how the utilisation of intellectual property rights (IPRs) by Canadian manufacturing firms is related to their characteristics, activities, competitive strategies and industry sector in which they operate. The principal source of information used in this endeavour is the Statistics Canada Survey of Innovation 1999.

The paper starts with an overview of other studies that looked at the use of intellectual property rights in Canada. Follows a conceptual framework presenting variables likely to explain the use specific IPRs by Canadian manufacturing firms.

The use of IPRs is to a great extent correlated with basic economic characteristics of firms, their activities and industry environment. A series of estimated logit regressions predict the probability that a firm will use a specific IPR instrument. Also estimated is the contribution of the use of IPRs to the probability that a firm innovates.

The decision of a firm to use IPRs is often not independent of the decision to innovate. To eliminate the potential endogeneity bias I estimate a two-stage logit model. A comparison of the single- and two-stage logit models shows that the nexus from the protection of intellectual property (patents) to innovation may be weaker than indicated by the single equation model.  相似文献

Changes in agricultural land use have important implications for environmental services. Previous studies of agricultural land‐use futures have been published indicating large uncertainty due to different model assumptions and methodologies. In this article we present a first comprehensive comparison of global agro‐economic models that have harmonized drivers of population, GDP, and biophysical yields. The comparison allows us to ask two research questions: (1) How much cropland will be used under different socioeconomic and climate change scenarios? (2) How can differences in model results be explained? The comparison includes four partial and six general equilibrium models that differ in how they model land supply and amount of potentially available land. We analyze results of two different socioeconomic scenarios and three climate scenarios (one with constant climate). Most models (7 out of 10) project an increase of cropland of 10–25% by 2050 compared to 2005 (under constant climate), but one model projects a decrease. Pasture land expands in some models, which increase the treat on natural vegetation further. Across all models most of the cropland expansion takes place in South America and sub‐Saharan Africa. In general, the strongest differences in model results are related to differences in the costs of land expansion, the endogenous productivity responses, and the assumptions about potential cropland.  相似文献

Integrated Assessment studies have shown that meeting ambitious greenhouse gas mitigation targets will require substantial amounts of bioenergy as part of the future energy mix. In the course of the Agricultural Model Intercomparison and Improvement Project (AgMIP), five global agro‐economic models were used to analyze a future scenario with global demand for ligno‐cellulosic bioenergy rising to about 100 ExaJoule in 2050. From this exercise a tentative conclusion can be drawn that ambitious climate change mitigation need not drive up global food prices much, if the extra land required for bioenergy production is accessible or if the feedstock, for example, from forests, does not directly compete for agricultural land. Agricultural price effects across models by the year 2050 from high bioenergy demand in an ambitious mitigation scenario appear to be much smaller (+5% average across models) than from direct climate impacts on crop yields in a high‐emission scenario (+25% average across models). However, potential future scarcities of water and nutrients, policy‐induced restrictions on agricultural land expansion, as well as potential welfare losses have not been specifically looked at in this exercise.  相似文献

A model of optimal advertising expenditures in a dynamic duopoly   总被引:7,自引:0,他引:7  
This paper develops a dynamic model of oligopolistic advertising competition. The model is general enough to include predatory advertising and informative advertising as particular cases. The analysis is conducted in a differential game framework and compares the open-loop and feedback equilibria to the efficient outcome. It is found that for the informative advertising competition game, advertising levels are closer to the collusive outcomes in a feedback equilibrium. In the case of predatory advertising, expenditures are inefficiently high in a feedback equilibrium and the open-loop solution is more efficient.  相似文献

Do house prices reflect fundamentals? Aggregate and panel data evidence   总被引:2,自引:1,他引:1  
We investigate whether recently high and consequently rapidly decreasing U.S. house prices have been justified by fundamental factors such as personal income, population, house rent, stock market wealth, building costs, and mortgage rate. We first conduct the standard unit root and cointegration tests with aggregate data. Nationwide analysis potentially suffers from problems of the low power of stationarity tests and the ignorance of dependence among regional house markets. Therefore, we also employ panel data stationarity tests which are robust to cross-sectional dependence. Contrary to previous panel studies of the U.S. housing market, we consider several, not just one, fundamental factors. Our results confirm that panel data unit root tests have greater power as compared with univariate tests. However, the overall conclusions are the same for both methodologies. The house price does not align with the fundamentals in sub-samples prior to 1996 and from 1997 to 2006. It appears that the real estate prices take long swings from their fundamental value and it can take decades before they revert to it. The most recent correction (a collapsed bubble) occurred around 2006.  相似文献

This study investigates the factors affecting the loan quality of banking sector in seventeen emerging and developing markets using quarterly panel dataset covering period of 2010–2019 and utilising feasible generalised least square methodology. Our empirical analysis suggests that inflation and lending rates negatively affect the banks’ loan quality measured by non-performing loans. On the contrary, economic growth and capital adequacy show a positive impact on banks’ loan quality. The inclusion of the ratio of net open position in foreign exchange to capital and its’ lagged values, as an additional factor, has marked out this research from other studies. Our results reveal that the ratio has a significant negative impact on loan quality in banking. This finding, as it was also seen in Asian crises of 1997, indicates that the higher the ratio net open position in foreign exchange to capital cause moral hazard problem leading to the higher non-performing loans in banking sectors.
