Faced with a record level of unemployment, the present debate in Germany is to extend the weekly hours of work. In this paper the employment effects of an economy-wide increase in weekly hours are quantified on the basis of a computable general equilibrium model for different specifications of the wage setting rule and the use of additional policy-induced public income. The simulation results back the argument of the opponents of longer working time that not more jobs will be created. However, when the higher tax revenues from GDP growth are used to reduce social security contributions, then the claim of the proponents that more jobs will be created can be supported. 相似文献

In horticultural markets, trade barriers often apply to the processed products whereas domestic support applies to farm-produced raw commodities. Here we assess the effects of such trade barriers and domestic support by simulating the effects of policy reform on global processing tomato markets, which are faced with modest processed product tariffs and high domestic support in the European Union (EU). Both protection and EU subsidy drive down world welfare, but we find that reducing import tariffs for tomato products would yield greater effects on markets and larger welfare impacts outside Europe than would reductions in EU domestic support. 相似文献

This empirical study of business‐to‐business service firms examines the determinants and effects of control rights to intellectual assets in a property rights theoretic framework. Regression analyses using survey data suggest that service suppliers that retain control over their intellectual output are more innovative. In long‐term relationships, service firms' clients may thus be better off balancing their need to control outsourced activities with the suppliers' incentives to invest in learning and innovation. Additionally, and aligned with property rights theoretic predictions, service suppliers' bargaining power and their indispensability in service projects are positively associated with their ability to retain control rights. In contrast, innovation capabilities are not very significant in determining control rights allocation between service suppliers and their clients. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

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

Impacts of Declining U.S. Retail Beef Demand on Farm-Level Beef Prices and Production 总被引:1,自引:0,他引:1
A systems model was estimated to determine the effects of declining U.S. retail beef demand on farm-level beef prices and production. Retail beef demand declined by nearly 66% from 1976 to 1999. Results indicate autonomous shifts in retail demand significantly impacted farm-level demands and production. Based on equilibrium multipliers, the 1976–99 reduction in beef demand decreased real slaughter cattle prices and production by 32.1% and 11.2%, respectively. Real feeder cattle prices and production decreased by 8.0% and 22.6%, respectively. Combining the decreases in farm prices and production, slaughter and feeder cattle producers experienced a real revenue reduction of $13.3 billion (61%) due to the long-term decline in demand. 相似文献

West and Central Africa (WCA)’s cotton sector is experiencing rising production costs and lower yields, reversing decades of growth. Declining input use, soil fertility and inefficient chemical pest controls are contributing factors. We evaluate the potential impact of Bt cotton on WCA using a multiregion general equilibrium model and multicountry estimates of Bt-induced productivity. We find that Bt cotton raises growers’ returns, land value and welfare. Released labor from cotton is shifted to food crops hence reducing labor shortage constraints. Overall, results indicate that potential gross benefits from Bt cotton are substantial for WCA cotton sector, and that the economic costs of nonadoption are equally significant. 相似文献

I model imperfect information, derive a downward sloping market demand curve, and explain vacancies in a partial equilibrium model of a rental housing market. Tenants can be completely described by an exogenous demand curve, perhaps arising from differences in income, preferred location, or tastes, and view vacant units based on a stochastic arrival of rental information. Free entry of these landlords induces excess rental housing capacity (equilibrium vacancies). I determine the equilibrium distribution of rents for vacant units, show that this rent distribution may be discontinuous, and explore the equilibrium vacancy rate to changes in exogenous parameters. The resulting characterization of equilibrium distributions of rents may be amenable to econometric modeling exploring the relationship between market rents and vacancies. 相似文献

Rule l0b-5 of the 1934 Securities and Exchange Act allows investors to sue firms for misrepresentation or omission. Since firms are principal–agent contracts between owners – contract designers – and privately informed managers, owners are the ultimate firms’ voluntary disclosure strategists. We analyze voluntary disclosure equilibrium in a game with two types of owners: expected liquidating dividends motivated (VMO) and expected price motivated (PMO). We find that Rule l0b-5: (i) does not deter misrepresentation and may suppress voluntary disclosure or, (ii) induces some firms to adopt a partial disclosure policy of disclosing only bad news or only good news. 相似文献

A dynamic approach to the analysis of strategic alliances 总被引:1,自引:0,他引:1
The increasing trend in strategic alliance formation between major firms around the world, has prompted researchers from various disciplines to look at this phenomenon in great detail. In this paper, we review alternate approaches in the literature in this area. We then propose a non-linear dynamic approach to study the formation of competitive strategic alliances and contrast it with the traditional game-theoretic approach. The pros and cons of these two approaches are discussed with reference to a competitive alliance scenario. Dynamic models have significant managerial implications as they enable us to investigate ‘if-then’ type scenarios and project the impact of different strategies. 相似文献

中国城市可持续发展的国际借鉴 总被引:2,自引:0,他引:2
随着世界各国城市发展不断地向前推进,然而把发展目标具体化为追求GNP的增长而忽略社会和环境方面的指标,导致城市的可持续发展面临社会和环境问题的尴尬。为此,本文从制定和执行可持续发展政策的角度,举例美国旧金山、加拿大柏林顿城市的可持续发展实施概况,从中探索城市可持续发展的一般规律,寻求中国城市最优化可持续发展模式。 相似文献
