Can economically efficient outcomes be obtained and sustained in the absence of externally enforced property rights? We study the evolutionary properties of a game that exhibits two well-defined Nash equilibria: one generates an inefficient outcome while the other set generates an efficient outcome supported by the potential for retaliation. Although standard forward-looking refinements eliminate the efficient equilibrium, neither equilibrium type satisfies strict evolutionary stability criteria. However, both types of equilibrium define strategies that are neutrally stable, which makes them vulnerable to drift in dynamic environments. We conduct computer simulation experiments in which players learn adaptively via a tournament selection mechanism called sophisticated experimentation. Our simulations demonstrate that while the system spends a disproportionately high proportion of time in the inefficient equilibrium set, the efficient equilibrium is pervasive as the system drifts back and forth between the equilibrium sets, never settling on one or the other.  相似文献

Financial primitives are introduced to define acceptable loss exposures when demands and supplies are defined on differing event spaces. Acceptable loss exposures are modeled by a convex cone of random variables containing the nonnegative random variables. The resulting financial equilibrium defines in general a two price economy. Analytical procedures for identifying the two prices are described. The size of the two price economy is fundamentally determined by the financial system that determines the size of the cone of acceptable losses. There are implications for accounting and risk management as liabilities would typically be valued at ask while assets are valued at bid with no data available on bidirectional prices for anything. Marking to market in such financial economies is at best marking to two price economies.  相似文献

It is often stated that real house prices respond to inflation in ways similar to assets infixed supply, such as gold or antiques. This paper proposes that, instead, house prices are determined primarily by the cost of producing new houses. Thus, inflation affects price mainly through input markets and through expansion in housing starts. This proposition is supported in an examination of annual changes in house prices between 1965 and 1982 in 12 sub regions of the United States  相似文献

In the consumer behavior context, multiattribute attitude models used to predict consumer choice in multiple criteria decision making situations have produced mixed results. Prediction of consumer behavior from attitudes, consequently, has been highly debated in recent years with researchers using beliefs-only, full, and extended multiattribute attitude models. The research underlying this paper was designed to compare the predictive superiority of the beliefs-only model, the full multiattribute attitude model, and a new representation identified as the combined multiattribute/determinant attribute attitude model. Data concerning patronage of fast-food chains were collected from a student panel for seven weeks. Predictive superiority was determined by average adjusted R2 using the patronage behavior dependent variable. All models were tested in aggregated and disaggregated form.  相似文献

We examine an export game where two (home and foreign) firms produce vertically differentiated products. The foreign firm is more R&D efficient and is based in a larger and richer market. The unique (risk‐dominant) Nash equilibrium exhibits intra‐industry trade, and the foreign producer manufactures a higher‐quality product. When transport costs are low, unilateral dumping by the foreign firm arises; otherwise, reciprocal dumping occurs. For some parameters, a domestic antidumping policy leads to a quality reversal in the international market whereby the home firm becomes the quality leader. This policy is desirable for the implementing country, though world welfare decreases.  相似文献

This paper introduces new measures of the mean and variance of inflation and growth expectations, based on tendency survey data from four major European economies. The expectations measures are technically ‘irrational’, but more accurate than naive alternatives; expectations errors do not persist for more than a year. Unexpected inflation, and uncertainties about inflation and growth, play the roles assigned them by New Classical macroeconomic theory, respectively raising and lowering real activity. All the expectations, uncertainties and errors appear more closely correlated across countries than experience would justify, suggesting that unpredictable disturbances typically have an internal rather than an international origin.  相似文献

Abstract. The labor turnover rate in Japan is less than half the US level. A small-scale survey of companies that operate in both Japan and the USA was conducted to examine reasons for the discrepancy. The main findings are that Japanese human resource policies, including steep seniority-earnings profiles, extensive fringe benefits, participatory management, and a reluctance to recruit experienced workers from other firms, contribute to the lower Japanese turnover rate. Additionally, workers of Japanese descent in the USA have a somewhat lower labor turnover rate than other Americans, suggesting some role for cultural differences.  相似文献

This paper analyzes countertrade as a special case of a customs union in which the countertrade agreement gives rise (as in customs union theory) to both trade-creating and trade-diverting effects. The net effects on welfare are ambiguous. A detailed case study from Egypt and brief examples from other countries illustrate the relevance of this interpretation .  相似文献

This special issue contributes to the development economics literature by highlighting the role of information communication and technologies (ICTs) in supporting rural and agricultural development. It is comprised of nine papers. Key findings from this special issue include: (1) internet use increases rural consumption diversity and agricultural productivity; (2) smartphone use empowers rural women in household decision-making and off-farm work participation; (3) smartphone-based agricultural extension services boost rural income growth; (4) a lack of ICT infrastructure and inadequate skills to use digital technologies are two key factors that lead to digital poverty traps for smallholder rural farmers; (5) ICT adoption increases the probability of rural households' access to credit and empowers rural women and farm households in relatively less developed regions to access credit; (6) digital financial inclusion reduces farmers' vulnerability to poverty; and (7) e-commerce adoption increases both sales prices and marketing costs, but the magnitude of increasing the former is higher than the magnitude of increasing the latter, which finally contributes to a higher gross return. This special issue also proposes practical instruments and implications for advancing the application of ICTs in rural areas to accelerate rural and agricultural development in the digital age.  相似文献
