We show that for an open dense set of markets with a continuum of traders the number of equilibrium allocations [which by the celebrated theorem of Aumann (Econometrica. 1964, 32. 39–50) coincide with the core allocations for such markets are finite. This presents a limiting case result that complements similar asymptotic theorems for cores of large economies proved by Bewley (Econometrica 1973, 41, 425–454), and Dierker (Journal of Mathematical Economics 1975, 2. 155–169). If we require that the measure on the space of agents be one with a finite number of atoms of equal weight, our reasoning recovers the classical results obtained by Debreu (Econometrica. 1970. 38, 387–392) for economies with a finite number of agents. 相似文献

Large sample approximations for sequential U-statistics using anti-symmetric kernels are considered both under no-change and change hypotheses. These new approximations
make it easy to perform sequential tests.

This article provides a test of the Fisher model, linking expected stock returns and inflation, based on international data. Since the Fisher model is ‘universal’ and calls for a slope of 1 in any country, we improve the testing power by conducting a joint test over eight countries. The pooling of data for several countries seems to reduce the small-sample bias. We test the Fisher model, using an instrumental variable approach, for holding-period horizons ranging from 1–12 months. The Fisher model is not rejected at any horizon: however, the magnitude of the slope coefficient lends stronger support at long horizons. This study using multi-country panel data provides evidence corroborating the finding of Boudoukh and Richardson (1993) that the Fisher model holds at long horizons (5 years), using 180 years of US data. 相似文献

In the wake of unification, the former GDR became a member of the DM monetary zone. We evaluate whether unified Germany satisfies the criteria defining an optimal monetary area. We conclude that the primary criterion, similarity of shocks, is not satisfied even by the western states, a reflection of the importance of sector-specific relative to geographic shocks coupled with different sectoral structures. Extending this argument, we conclude that the correlation of shocks to the eastern states with western states is also likely to be small. A case for monetary unification must, in consequence, be based on political rather than narrowly economic calculations. 相似文献

政府收支分类是观察和研究政府公共经济行为的基础,完善的政府收支分类是实现善治的重要工具和必要条件。目前正在进行的政府收支分类改革在改善政府治理水平方面取得了较为令人满意的成果:它调整了政府收支分类体系的结构,扩大了收支分类涉及的范围,细化了收支分类的内容;并由此提高了政府行为的透明度,改善了公共决策的合意性,强化了对决策执行过程的财政控制,提升了公共监督的效力。不过,目前的改革成果与理想状态相比,在系统性、全面性、准确性和细致性方面仍然存在一定的差距。为此,建议政府进一步拓展支出分类维度,调整部分科目的类别归属,并在条件成熟的时候逐步扩大收支分类的内容范围。 相似文献

We use new data on the timing of the transition to agriculture, developed by Putterman and Trainor (2006), to test the theory of Diamond (1997) and Olsson and Hibbs (2005) that an earlier transition is reflected in higher incomes today. Our results confirm the theory, even after controlling for institutional quality and other geographical factors. The date of transition is correlated with prehistoric biogeography (the availability of wild grasses and large domesticable animal species). The factors conducive to high per capita incomes today are good institutions, an early transition to agriculture, access to the sea and a low incidence of fatal malaria. Geographical influences have been at work in all of these proximate determinants of per capita income. 相似文献

This paper focuses on examining the effects of financial development and liberalization on knowledge accumulation. The results consistently show that while financial development facilitates the accumulation of new ideas, the implementation of financial reform policies is negatively associated with it. The undesirable effects of financial liberalization are found to operate through the triggering of crises and volatility in the financial system. There is also evidence supporting the hypothesis that financial liberalization reallocates talent from the innovative sector to the financial system, thus retarding technological deepening. Moreover, the findings also suggest that increased R&D activity and the presence of a stronger intellectual property rights protection framework tend to have beneficial effects on knowledge accumulation. 相似文献

This paper examines the importance of credit market shocks in driving global business cycles over the period 1988:1–2009:4. We first estimate common components in various macroeconomic and financial variables of the G-7 countries. We then evaluate the role played by credit market shocks using a series of VAR models. Our findings suggest that these shocks have been influential in driving global activity during the latest global recession. Credit shocks originating in the United States also have a significant impact on the evolution of world growth during global recessions. 相似文献

This paper decomposes consumption risk sharing among provinces in China over the 1980–2007 period. We find that 9.4% of the shocks to gross provincial product are smoothed by the interprovincial fiscal transfer system. This system also cushions a relatively large fraction of the province-specific shocks in the coastal provinces of China. Using a variety of indicators, we explore non-fiscal channels of consumption risk sharing. We find that the migration of rural labor to urban areas and the remittance of migrant wages play important roles in promoting interprovincial consumption risk sharing in the inland provinces of China. In contrast, the extent of risk sharing through financial intermediaries and the capital markets is very limited. These factors have resulted in a low degree of risk sharing among Chinese provinces, especially over the last decade. 相似文献
