非均衡的经济动态模型 总被引:6,自引:1,他引:6
本文旨在按现实世界的本来面目建立一个非均衡的内生经济动态模型。在这个模型中 ,源于部门内和部门间关系的内生变量导致资本市场、消费品市场上产量和价格的波动。市场的非均衡过程、存货调节机制以及经济人的最优行为和适应性行为是基于对现实世界的观察进行模拟的。静态性质及其稳定性是作为一般市场动态过程的特例加以讨论的。 相似文献

Summary. In this paper, we develop an endogenous growth model with market regulations on explicitly modeled financial intermediaries
to examine the effects of alternative government financing schemes on growth, inflation, and welfare. In the presence of binding
regulation, there is always a unique equilibrium. We perform four alternative policy experiments; a change in the seigniorage
tax rate, a change in the seigniorage tax base, a change in the income tax and a change in the fiscal-monetary policy mix.
We find that in the presence of binding legal reserve requirements, a marginal increase in government spending need not result
in a reduction in the rate of economic growth if it is financed with an increase in the seigniorage tax rate. Raising the
seigniorage tax base by means of an increase in the reserve requirement retards growth and it has an ambiguous effect on inflation.
An increase in income tax financed government spending also suppresses growth and raises inflation although not to the extent
that the required seigniorage tax rate alternative would. Switching from seigniorage to income taxation as a source of government
finance is growth reducing but deflationary. From a welfare perspective, the least distortionary way of financing an increase
in the government spending requirements is by means of a marginal increase in the seigniorage tax rate. Under the specification
of logarithmic preferences, the optimal tax structure is indeterminate.

Price caps have been shown to have incentive properties superior to traditional rate of return regulation. Average-revenue-lagged regulation (ARL) is attractive in that steady-state prices are known to be efficient. We show that the ARL scheme can be manipulated by the firm so as to yield the unregulated global profit maximum. While tests exist that can provide the regulator with evidence of this strategic behavior, we also demonstrate that the unregulated global profit maximum will not be attainable if Laspeyres (L) regulation is employed.Jel classification: L43, L51I would like to thank Michael Crew and an anonymous referee for their extremely helpful suggestions. 相似文献

Governmental entities at all levels are empowered to acquire private property for the public's benefit, provided that just compensation is paid. The level of compensation typically viewed by courts as just is market value, but questions arise as to whether market value compensation motivates the private owner of land, potentially subject to a taking, to improve the property to a degree that is socially efficient. Earlier works have found market value to be a compensation level too high to promote efficiency. The present paper offers an analysis, based on a simple model of investor profit maximization, that provides a unified view of models presented in some important earlier works. In a special application of the general case, it is shown that market value can be too low a level of compensation to promote efficient behavior by the land owner. 相似文献

The Effects of Megamergers on Efficiency and Prices: Evidence from a Bank Profit Function 总被引:4,自引:0,他引:4

This paper examines the efficiency and price effects of mergers by applying a frontier profit function to data on bank megamergers. We find that merged banks experience a statistically significant 16 percentage point average increase in profit efficiency rank relative to other large banks. Most of the improvement is from increasing revenues, including a shift in outputs from securities to loans, a higher-valued product. Improvements were greatest for the banks with the lowest efficiencies prior to merging, who therefore had the greatest capacity for improvement. By comparison, the effects on profits from merger-related changes in prices were found to be very small. 相似文献

This paper considers price discrimination when competing firms do not observe a customer’s type but only some other variable correlated to it. This is a typical situation in many insurance markets—such as motor insurance—where it is also often the case that insurance is compulsory. We characterise the equilibria and their welfare properties under various price regimes. We show that discrimination based on immutable characteristics such as gender is a dominant strategy, either when firms offer policies at a fixed price or when they charge according to some consumption variable that is correlated to costs. In the latter case, gender discrimination can be an outcome of strategic interaction alone in situations where it would not be adopted by a monopolist. Strategic price discrimination may also increase cross subsidies between types, contrary to expectations.JEL Classification No.: L13, G22 相似文献

An unusually rich source of data on housing prices in Stockholm is used to analyze the investment implications of housing choices. This empirical analysis derives market-wide price and return series for housing investment during a 13-year period, and it also provides estimates of the individual-specific, idiosyncratic, variation in housing returns. Because the idiosyncratic component follows an autocorrelated process, the analysis of portfolio choice is dependent upon the holding period. We analyze the composition of household investment portfolios containing housing, common stocks, stocks in real estate holding companies, bonds, and t-bills. For short holding periods, the efficient portfolio contains essentially no housing. For longer periods, low-risk portfolios contain 15 to 50 percent housing. These results suggest that there are large potential gains from policies or institutions that would permit households to hedge their lumpy investments in housing. We estimate the potential value of hedges in reducing risk to households, yet yielding the same investment returns. The value is surprisingly large, especially to poorer homeowners. 相似文献
