We analyze the gains from trade for a small cash-in-advance economy with endogenous labor supply and learning-by-doing in
the accumulation of human capital. Contrary to previous findings, we show that free trade is not optimal independently of
the relative amount of cash required for the purchase of each good. Furthermore, a monetary rule à la Friedman can eliminate
distortions deriving from the cash-in-advance constraint only under segmented financial markets; in any case, it cannot restore
the economic optimum. Finally, we identify government intervention policies, such as wage and export subsidies, that can be
welfare improving. 相似文献

提出城市适度人口规模不是一个静态的数值,而是动态的过程。不是一个先验的数值,而是系统决定的综合结果。建立了一个适度人口规模的概念性框架,即EFL模型,就是说合理和适度的人口规模是与之相联系的资源环境因素、功能和经济方式、空间区位状态共同决定的结果。生态系统的变动,综合决定了一定时期、一定标准下的城市人口适度规模,并决定了这一适度规模的变化趋势。基于这一思路,讨论了影响上海人口规模变动的积极因素和阻碍因素,从资源环境变化、城市功能变化和城市空间变化三个方面对上海适度人口规模的变动趋势作了基本判断,提出上海人口规模将出现先上升再下降的趋势。根据动态适度人口规模的观点,对城市人口综合调控和城市管理的有关问题提出了一些建议。 相似文献

This paper proposes an approach to the intraday analysis of diversified world stock accumulation indices. The growth optimal portfolio (GOP) is used as reference unit or benchmark in a continuous financial market model. Diversified portfolios, covering the world stock market, are constructed and shown to approximate the GOP, providing the basis for a range of financial applications. The normalized GOP is modeled as a time transformed square root process of dimension four. Its dynamics are empirically verified for several world stock indices. Furthermore, the evolution of the transformed time is modeled as the integral over a rapidly evolving mean-reverting market activity process with deterministic volatility. The empirical findings suggest a rather simple and robust model for a world stock index that reflects the historical evolution, by using only a few readily observable parameters.

An endogenous growth model with human capital formation, pollution caused by production of consumption goods, and endogenous fertility decisions made by altruistic agents with infinite horizons is presented. Consequences for optimal policy of modelling fertility as an explicit decision variable are examined. Because ordinary lump-sum transfers to individuals are no longer neutral, either revenue from a pollution tax must be redistributed to dynasties (working as an implicit tax on child births), or lump-sum transfers must be supplemented with an explicit fertility tax. Alternatively, the government can avoid distortions of the fertility decisions by maintaining an appropriate public debt. When abatement is highly productive, it can be optimal to subsidize fertility in order to increase total production. 相似文献

Little attention has been paid in the literature to the impact of different investment horizons on the portfolio compositiondespite its importance to portfolio managers. One exception isthe study by Gunthorpe and Levy (1994) on the U.S. stock market.Our paper extends the same study to the stock markets of Japan,Hong Kong and Korea. Using 40 individual stocks in each market,our results support those of Gunthorpe and Levy (1994) in thatthe composition of an optimal portfolio depends heavily on theinvestment horizon. When the investment horizon lengthens, theproportion of defensive stocks becomes larger while that ofaggressive stocks becomes smaller. 相似文献

税务行政处罚的法理探析 总被引:1,自引:0,他引:1
法学意义上的税收是一种金钱给付关系。关于税收的法律关系性质有权利关系说和债务关系说两种观点,不同观点之下对于税务行政处罚的法理有不同的分析。事实上,国家和纳税人之间是一种公法意义上的债权债务关系,税务行政处罚是国家对纳税人不按时履行税收合约的一种惩罚。 相似文献

Testing for Vertical Fiscal Externalities 总被引:1,自引:1,他引:1

The purpose of this paper is to design a test of whether the vertical external effects associated with tax base sharing among local and regional governments have become internalized via the intergovernmental transfer system. Such tests are important in the sense that the income tax rates chosen by different levels of government will generally be correlated, even if the resource allocation is optimal from society's point of view. By using panel data for the Swedish local and regional public sectors, the results imply that an increase in the regional income tax rate induces the municipalities in the region to decrease their income tax rates. In addition, we are able to reject the null hypothesis that the vertical external effects have become internalized. 相似文献

Monetary policy in the United States has been documented to have switched from reacting weakly to inflation fluctuations during the 1970s, to fighting inflation aggressively from the early 1980s onward. In this paper, I analyze the impact of the U.S. monetary policy regime switches on the Eurozone. I construct a New Keynesian two‐country model where foreign (U.S.) monetary policy switches regimes over time. I estimate the model for the U.S. and the Euro Area using quarterly data and find that the United States has switched between those two regimes, in line with existing evidence. I show that foreign regime switches affect home (Eurozone) inflation and output volatility and their responses to shocks, substantially, as long as the home central bank commits to a time‐invariant interest rate rule reacting to domestic conditions only. Optimal policy in the home country instead requires that the home central bank reacts strongly to domestic producer‐price inflation and to international variables, such as imported goods relative prices. In fact, I show that currency misalignments and relative prices play a crucial role in the transmission of foreign monetary policy regime switches internationally. Interestingly, I show that only marginal gains arise for the Euro Area when the European Central Bank (ECB) adjusts its policy according to the monetary regime in the United States. Thus, a simple time‐invariant monetary policy rule with a strong reaction to Producer Price Index (PPI) inflation and relative prices is enough to counteract the effects of monetary policy switches in the United States. 相似文献
