This paper presents an experimental study of dynamic indefinite horizon R&D races with uncertainty and multiple prizes. The
theoretical predictions are highly sensitive: small parameter changes determine if we should expect technological competition,
and if so whether it is sustained, or if the market converges into one with entrenched leadership and lower aggregate R&D.
The subjects’ strategies are far less sensitive. In most of the treatments, the R&D races tend to converge to entrenched leadership.
We propose and apply a quantal response extension of Markov perfection that is qualitatively and largely quantitatively consistent
with the experimental observations. 相似文献

No End to the Racial Wage Hierarchy in South Africa? 总被引:2,自引:0,他引:2
The South African apartheid system formally ended with the election of the African National Congress at the first all-race elections held in 1994. As a result, racist policies such as color barring, that particularly hindered the advancement of black workers throughout the apartheid period, are no longer legal. Yet the legacy of apartheid may endure as a result of both the persistence of racial differences in human capital attributes and the possible continuation of discriminatory practices within employment. In this paper the authors examine the evolution of the racial wage hierarchy in the early post-apartheid era against the background of the long-term decline in racial wage disparities observed over the last years of the apartheid regime. They find evidence that the position of black workers between 1995 and 1997 actually deteriorated relative to the overall geometric mean wage, while that of colored, Asian, and white workers improved. 相似文献

This paper asks whether the income gap between rich and poor nations can be explained by multiple equilibria. We explore the
quantitative implications of a simple two-sector general equilibrium model that gives rise to multiplicity, and calibrate
the model for 127 countries. Under the assumptions of the model, around a quarter of the world’s economies are found to be
in a low output equilibrium. We also find that, since the output gains associated with an equilibrium switch are sizeable,
the model can explain between 15 and 25% of the variation in the logarithm of GDP per worker across countries. 相似文献

An explicit model of communication and informational equilibrium is constructed and some results generalizing Aumann's theorem on the impossibility of agreeing to disagree are obtained, together with an example showing that full rationality may be sub-optimal. 相似文献

Summary In overlapping-generations models of fiat money, the existence of a Pareto-optimal equilibrium — which defines an optimal quantity of money — is more general than well-known counter-examples suggest. Those examples, having no optimal equilibrium just because there are small variations in households' tastes and endowments across generations, are not typical. On the contrary: For an open-dense, full-measure subset of smooth stationary economies and an open-dense subset of continuous stationary economies, introducing small variations in tastes and endowments across generations preserves the existence of an optimal equilibrium. Put simply, optimal equilibria generically exist for nearly-stationary economies.I thank Scott Freeman, Katsuhiko Kawai, and two referees for proofreading this text; all lead to clarifications. 相似文献

From Dependency to Defiance? Work‐Unit Relationships in China’s State Enterprise Reforms 总被引:1,自引:0,他引:1
This paper outlines the economic reform process being undertaken in China and the subsequent partial closure and radical down-sizing of the state-owned enterprise sector. Redundancies arising out the restructuring process have eroded the state-worker contract of the iron rice-bowl. This has resulted in growing and sometimes violent labour unrest. The planned workforce projections until the end of the year 2000 suggest that the numbers of redundancies has increased, adding to China's 'surplus labour' problem. A critical issue is thus whether the Chinese government, together with state-enterprise management, can contain potential future labour and civil unrest using its present methods. 相似文献

Recent events have sparked renewed interest in disaster mitigation for public infrastructures. Presidential Decision Directive 63 identifies water distribution as being among the most vital and vulnerable of our large-scale infrastructures. Water distribution networks are vulnerable to threats such as chemical and biological contamination, cyber attacks on computer-based management systems, and physical destruction from acts of nature and intentional attack. This research develops methods for configuring the undamaged portion of the water network to mitigate the consequences of physical destruction. The approach is to find a hydraulically feasible residual network that can be pressurized to meet the demand of a subset of demand sectors. Demand sectors not pressurized then receive water through truck distribution from pressurized sectors. The objective is to minimize weighted water shortage and water truck distribution costs by identifying sectors to pressurize along with an assignment of unpressurized sectors to pressurized sectors for water delivery by truck. The paper develops an optimization model, describes a solution method, and presents computational results for three example networks. 相似文献

We generally establish equilibrium asset prices than can include price bubbles yet (a) be robust to truncations of the economy and (b) exclude trade in non-consumables, like money, stock certificates, or land deeds. 相似文献
