The case of German reunification has been subject to extensive research on earnings inequality and labour market integration. However, little is known about the development of equality of opportunity (EOp) in East and West Germany after 1990. Using German micro data, we empirically analyse how circumstances beyond the sphere of individual control relate to inequality in East and West Germany. Our results show that EOp is larger in East than in West Germany. However, despite increasing income inequality, EOp remained surprisingly constant.  相似文献

This paper constructs a model of the recorded music market to investigate the consequences of local content requirements in broadcasting for the “internationalization” of domestic music. It models the entry decisions of bands, the contracting decisions of record companies, the airplay decisions of radio stations and the radio listening and recording purchasing decisions of consumers. The paper shows that a local content quota leads, perversely, to the increased internationalization of domestic music. A quota that also requires increased broadcasting of “new” music yields an additional welfare loss but does nothing to a record company's incentives to sign up new bands.  相似文献

Using a matched innovation survey and structural business statistics, we investigate the impact of the introduction of new service products and other types of technological innovations on firm growth measured as subsequent two-year employment growth. Results, based on median and robust regression methods for manufacturing firms, show that, on average, both the introduction of new goods and process innovations have a significant and positive impact on subsequent firm growth. In contrast, the introduction of new services does not, on average, have a significant impact on firm growth for both manufacturing and service firms. However, quantile regressions show that the introduction of new service products has a significant and positive impact on firm growth for high-growth service firms. Finally, in manufacturing, the introduction of product innovations has a positive impact on firm growth at both the lower and higher ends of distribution (i.e. for both high-growth and shrinking firms).  相似文献

The agreement to abolish the quotas on textiles and clothing introduced under the Multi‐fiber Arrangement (MFA) will create a new and much more competitive world market for India's exports of textiles and clothing. India's inefficient and costly policies, such as cotton export quotas, the hank yarn obligation, and the restrictive policies on foreign investment that have held back productivity in the Indian apparel sector, will impose serious costs. The authors consider the implications of reforming these policies in an open trading environment using a multiregion, applied general‐equilibrium model. They find that the costs of these policies to India increase substantially following abolition of the MFA; the benefits to India from domestic reforms are considerably enhanced when there is global free trade in textiles and apparel.  相似文献

The contrasting marketing principles of service-dominant (S-D) logic and goods-dominant (G-D) logic are examined in this article from the perspective of current research themes in the information science community. The conclusion is reached that much of the distributed multi-agent literature is complementary to the issues being explored concerning S-D logic, and that some multi-agent research may therefore be pertinent to the business marketing community. This article discusses the modelling approach of interactionism as an underlying principle of both S-D logic and multi-agent systems technology. The two domain technologies are compared, and implications for business marketing practice proposed.  相似文献

The paper provides a critical analysis of information requirements and rules on advice pursuant to the new Directive (EU) 2016/97 on insurance distribution (IDD). Following an introductory overview of the IDD and its “business conduct rules”, distribution- and product-related information duties and the rules on services with and without advice are discussed. Particular emphasis is laid on life insurance and coherence of the special rules concerning insurance-based investment products with the general requirements and those pursuant to MIFID II.  相似文献

We analyze a dynamic and stochastic ecological-economic model of grazing management in semi-arid rangelands. The ecosystem is driven by stochastic precipitation. A risk averse farmer chooses a grazing management strategy under uncertainty such as to maximize expected utility from farming income. Grazing management strategies are rules about which share of the rangeland is given rest depending on the actual rainfall in that year. In a first step we determine a myopic farmer's optimal grazing management strategy and show that a risk averse farmer chooses a strategy such as to obtain insurance from the ecosystem: the optimal strategy reduces income variability, but yields less mean income than possible. In a second step we analyze the long-run ecological and economic impact of different strategies. We conclude that a myopic farmer, if he is sufficiently risk averse, will choose a sustainable grazing management strategy, even if he does not take into account long-term ecological and economic benefits of conservative strategies.  相似文献

In this article, we combine two so far separate strands of the economic literature and argue that democratization leads to a real exchange rate appreciation. We test this hypothesis empirically for a sample of countries observed from 1980 to 2007 by combining a difference‐in‐difference approach with propensity score matching estimators. Our empirical results reveal a strong and significant finding: democratization causes real exchange rates to appreciate. Consequently, the ongoing process of democratization observed in many parts of the world is likely to reduce exchange rate distortions.  相似文献

The purpose of this paper is to provide new empirical evidence on frontier efficiency measurement in the international insurance industry, a topic of great interest in the academic literature during the last several years. A broad efficiency comparison of 6462 insurers from 36 countries is conducted. Different methodologies, countries, organizational forms, and company sizes are compared, considering life and non-life insurers. We find a steady technical and cost efficiency growth in international insurance markets from 2002 to 2006, with large differences across countries. Denmark and Japan have the highest average efficiency, whereas the Philippines is the least efficient. Regarding organizational form, the results are not consistent with the expense preference hypothesis, which claims that mutuals should be less efficient than stocks due to higher agency costs. Only minor variations are found when comparing different frontier efficiency methodologies (data envelopment analysis, stochastic frontier analysis).  相似文献

Use of short selling and derivatives is limited in most emerging markets because such instruments are not as readily available as they are in developed capital markets. These limitations raise questions about the value added provided by hedge funds, especially compared to traditional mutual funds active in these markets. We use five existing performance measurement models plus a new asset-style factor model to identify the return sources and the alpha generated by both types of funds. We analyze subperiods, different market environments, and structural breaks. Our results indicate that some hedge funds generate significant positive alpha, whereas most mutual funds do not outperform traditional benchmarks. We find that hedge funds are more active in shifting their asset allocation. The higher degree of freedom that hedge funds enjoy in their investment style might thus be one explanation for the differences in performance.  相似文献
