Drawing on a panel of advanced economies, this paper documents a concave and non‐monotonic link between inequality and the aggregate household saving rate. We find that, at a low level of inequality, more inequality is associated with higher saving; but we also show that a negative relationship between inequality and saving prevails where inequality is high. Using different empirical approaches, we locate the turning point, where the marginal effect of inequality turns from positive to negative, at a net income Gini coefficient of around 30. Moreover, we show that the relationship between inequality and saving also depends on financial market conditions. While inequality increases saving, when credit is scarce it tends to reduce saving at high levels of credit. This paper primarily focuses on household saving, yet we also find some evidence for a non‐monotonic effect of inequality on private saving, national saving, and the current account balance. 相似文献

ABSTRACT In Germany, retraining is an important measure in active labour market policy, providing unemployed individuals with extensive vocational training. Using administrative data, we show that retraining participants are more likely to take up jobs that require their educational degree and are more often employed in those occupations for which they have received vocational training. Moreover, retraining leads to higher earnings. As these effects may be driven by the positive impact of retraining on employment, we additionally try to isolate the direct effect by restricting our analyses to those formerly unemployed who find employment irrespective of participation in retraining. 相似文献

Experience during the financial crisis illustrates that the integrated measurement and management of different forms of risk remains a challenge for industry practitioners, researchers and financial supervisors alike. In the context of related literature, this article summarizes new research on the interaction of market and credit risk and implications for risk management that is presented in this special issue. The research covered highlights in particular the errors that can occur in the aggregation of the two types of risk and the strong relationships between them that suggest caution in the use of pragmatic distinctions between them. The article also touches on some research-based lessons for supervisory policies and suggests some directions for future research. 相似文献

World Trade Organization (WTO) negotiations rely on tariff reduction formulas. Formula approaches are of increasing importance in trade talks, because of the large number of countries involved, the wider dispersion in initial tariffs (e.g. tariff peaks), and gaps between bound and applied tariff rates. This paper presents a two country intra‐industry trade model with heterogeneous firms subject to high and low tariffs. We examine the welfare effects of applying three different tariff reduction formulas discussed in the literature that were used and proposed in previous and current General Agreement on Tariffs and Trade (GATT)/WTO negotiations (1) a proportional cut, (2) the Swiss formula and (3) a tiered formula. No single formula dominates for all conditions. The ranking of the three tools depends on the degree of product differentiation in the industry and the achieved reduction in the average tariff. 相似文献

This paper investigates the investment value of individual investors’ stock recommendations within online communities. We find that aggregated recommendations contain no explicit investment value and that following these recommendations may have a negative impact on investment performance. Our results suggest that recommendations are mostly based on simple heuristics and concentrate on a small number of stocks. When restricting the set of recommendations to those made by the most experienced or successful recommenders, results marginally improve but still preclude profitable investment strategies. Experienced and successful recommenders seem more likely to avoid the most expensive pitfalls rather than actually exhibit superior investment performance. 相似文献

This paper provides an argument for the advantage of a preference for identity‐consistent behaviour from an evolutionary point of view. Within a stylized model of social interaction, it is shown that the development of cooperative social norms is greatly facilitated if the agents possess a preference for identity‐consistent behaviour. As compliance with cooperative norms (in the long run) has a positive effect on the agents’ pay‐offs, it is argued that such a preference is evolutionarily advantageous. Notably, the argument, which assumes that agents always act in accordance with their preferences, also accounts for the cost of those features that are crucial for the selection process. 相似文献
