Dealing with integrated and near-integrated processes, this paper investigates the validity of regression on deterministic trends of K terms as K becomes large. It is found that the regression tends to be valid in spite of the true process being free from deterministic trends, which implies that the distinction between stochastic and deterministic trends disappears in K -asymptotics of the integrated and near-integrated processes. It is also shown that in K -asymptotics the usual unit root test, based on the model with deterministic trends of K terms, becomes useless against near-integration since the unit root distribution remains unchanged.

The Arrow impossibility theorem when individual preferences are weak orders is equivalent to the HEX game theorem. Because Gale showed that the Brouwer fixed point theorem is equivalent to the HEX game theorem, this paper indirectly shows the equivalence of the Brouwer fixed point theorem and the Arrow impossibility theorem. Chichilnisky showed the equivalence of her impossibility theorem and the Brouwer fixed point theorem, and Baryshnikov showed that the impossibility theorem by Chichilnisky and the Arrow impossibility theorem are very similar. Thus, Chichilnisky and Baryshnikov are precedents for the result—linking the Arrow impossibility theorem to a fixed point theorem. 相似文献

This paper investigates the expectation formation process of Japanese stock market professionals. By utilizing a monthly forecast survey dataset on the TOPIX distributed by QUICK Corporation, we sort forecasters into buy-side and sell-side professionals. We empirically demonstrate that the buy-side and sell-side professionals use either fundamental or trend-following strategies throughout their expectation formation processes and that they switch between fundamental and trend-following strategies over time. We also discuss that strategy switching can be key in understanding the persistent deviation of the TOPIX from the fundamentals. 相似文献

Abstract This paper studies the effects of trade liberalization on growth and long-run global income inequality using a two-country model of human capital accumulation by credit-constrained households. I show that the timing of trade liberalization is a crucial determinant of its effects on growth. Moreover, I show that the size of the long-run income gap between the two countries depends on the difference in domestic income inequality when they open up to trade. Based on these results, I analyze the effects of redistributive policy within a country. I show that redistribution in one country may increase income per capita of its trading partner if it is undertaken in a steady state, while the opposite is true if the policy is undertaken during transition. 相似文献

The stochastic volatility model of Heston (Rev Financ Stud 6(2):327–343, 1993) has found difficulty in describing some of the important features of implied volatility dynamics, leading to a quest for multifactor extensions as well as the incorporation of time-dependent model parameters. In this paper, an asymptotic expansion approach to the multifactor Heston model with time-dependent parameters is developed. The results of Benhamou et al. (SIAM J Financ Math 1(1):289–325, 2010) are extended and it is shown that the extension to the multifactor model involves an extra expansion term that captures the interaction between variance factors. The expansion formula under constant parameters can be explicitly computed and the incorporation of time-dependent parameters is straightforward under the framework. As illustration, a two-factor model is calibrated to data of index options and variance swaps and it is found that it is possible to distinguish a short-term and long-term variance factor from the implied volatility surface and variance swap rates. Moreover, the two-factor model is able to reproduce the shapes of the implied volatility surface during various market scenarios. 相似文献

20世纪60年代,伴随着日本经济起飞,城市加工产业对劳动力的需求急剧扩大,在城乡巨大收入差距的诱惑下,日本农村的青壮年劳动力大量涌入城市,造成农村劳动力严重短缺,在农户家庭内部劳动力互补机制的作用下,缓解了劳动力不足,在一定程度上稳定了农业生产。从分析日本经济起飞时期农村劳动力的结构变动入手,通过实证分析把握劳动力供给结构变化的经济影响;进而分析未来日本劳动力供给结构变化的趋势,在此基础上结合中国的实际情况说明农村劳动力互补机制对于城市化进程中中国农村的借鉴意义。 相似文献

This paper quantitatively assesses the impact of falling foreign direct investment (FDI) barriers on individual firms and its implications for intra-industry reallocation and aggregate productivity. We calibrate the firm-heterogeneity model of Eaton et al. (Econometrica 79(5):1453–1498, 2011) to match micro-level data on Japanese multinational firms facing fixed and variable costs of foreign production. We demonstrate that the calibrated model can be used to replicate the entry and sales patterns of Japanese multinationals. Counterfactual simulations show that declining FDI barriers lead to a disproportionate expansion of foreign production by more efficient firms relative to less efficient firms. A hypothetical 20 % reduction in FDI barriers is found to generate up to a 26.8 % improvement in industry-level productivity through global market-share reallocations within the industry. Compared with fixed entry barriers, reallocation effects and productivity gains are larger for a reduction of variable costs of foreign production. 相似文献

One overlooked reason for the persistence of distinct cultural values across rich democracies, we argue, is a country's labor market structure. Parents seeking to position their children for long‐term success would do well to instill values consistent with requirements of the labor market in the country where their children are likely to work. To the extent that labor markets are fluid, as in the United States, parents should teach their children to be resourceful and creative. In countries like Japan with relatively rigid labor markets, where workers have one chance to land a long‐term contract with a leading company, parents instead should instill the values of hard work and respect for authority. We find evidence consistent with this argument in survey experiments about attitudes in the United States and Japan about the desirability of employing immigrants for care work, and what values the immigrant care workers should hold. We also find evidence of indirect norm creation. American and Japanese respondents prefer immigrants—not just caregiving immigrants—whose values align with their country's type of valued human capital. 相似文献
