Learning by doing,spillovers and shakeouts 总被引:1,自引:0,他引:1
Jim?Y.?Jin Juan?Perote-Pe?a Michael?TroegeEmail author 《Journal of Evolutionary Economics》2004,14(1):85-98
This paper studies industry evolution driven by non strategic learning by doing and spillovers. We characterize a dynamic process of cost and output changes and its effect on welfare and industry profits. The paper gives conditions for shakeouts to occur and analyzes the key factors affecting these conditions. Since shakeouts could lead to a long-run social loss due to higher market concentration, there is a role for a government to play in limiting unnecessary shakeouts. The most effective way to do so is to enhance spillovers.JEL Classification:

经济体制改革的理论基础不仅仅是社会主义市场经济理论,生态经济理论也是其中之一,这是由生态经济理论原则及特点所决定了的。同时,改革的目标是建立社会主义市场经济体制,在新体制的建立过程中,也必须注意实现生态经济协调的几个问题。 相似文献

Government as a discriminating monopolist in the financial market: the case of China 总被引:2,自引:0,他引:2
Roger H. GordonWei Li 《Journal of public economics》2003,87(2):283-312
We show that the many unusual features of China’s financial markets are consistent with a government choosing regulations to maximize a standard type of social welfare function. Under certain conditions, these regulations are equivalent to imposing explicit taxes on business and interest income, yet should be much easier to enforce. The observed implicit tax rates are broadly in line with those observed in other countries. The theory also forecasts, however, that China will face increasing incentives over time to shift to explicit taxes. 相似文献

会计信息质量与市场定价分析 总被引:1,自引:0,他引:1
本文以应计质量、盈余持续性、盈余可预测性、盈余平滑度作为会计信息质量的代理变量,通过研究会计信息不同纬度的质量与权益资本成本之间的关系,为投资者的市场定价及对信息质量的关注程度提供证据。研究结果表明,除盈余的持续性不显著外,其他各项质量与权益资本成本之间均呈负相关关系;在对权益资本成本的影响程度方面,无论是单独影响还是条件影响,应计质量影响程度最大,其次是可预测性。 相似文献

Regulators often do not regulate all firms competing in a given sector. Due to product substitutability, unregulated competitors have incentives to bribe regulated firms to have them overstate their costs and produce less, thereby softening competition. The best collusion-proof contract entails distortions both for inefficient and efficient regulated firms (distortion ‘at the top’). But a contract inducing active collusion may do better by allowing the regulator to ‘team up’ with the regulated firm to indirectly tax its competitor. The best such contract is characterized. It is such that the unregulated firm pays the regulated one to have it truthfully reveals its inefficiency. We finally compare those contracts. 相似文献

Markets for illicit drugs present an interesting case study for economics, combining non-standard characteristics such as addiction and product illegality. One response has been to argue the generality of economic principles by suggesting that they apply even in the extreme case of markets for addictive substances, e.g., by showing that demand for illicit goods is responsive to price [1] [Reframing health behavior change with behavioral economics. Hillsdale, NJ:Lawrence Earlbaum Associates; 2000. p. 89-111.] and even by modeling addiction as rational [2] [J Political Econ 1988;96:675-700]. This paper sketches examples of an alternative reaction, focusing on idiosyncrasies of drug markets that might plausibly create counter-intuitive effects, including supply curves that slope downward because of enforcement swamping and/or a good serving as the only available store of wealth for its producer, demand reduction programs that increase demand, and consumption by “jugglers” possibly increasing rather than decreasing as prices rise. This analysis yields non-obvious policy recommendations; for example, source country control programs should concentrate on growing regions with a healthy banking sector. 相似文献

We estimate the pro-competitive effects of Austrias participation in the Single Market after its European Union (EU) accession in 1995 in terms of firms market power as measured by the Lerner index, using a sample of 46 industries and 7 industry groups, covering the period 1978–2001. In the framework of the markup estimation method suggested by Roeger (1995), we test for both an instantaneous structural break between 1993 and 1998 and also estimate logistic smooth transition models to take up the proposition that the regime shift is likely to have occurred gradually rather than as a big bang. In sum, the results provide no reason for being euphoric: Pronounced markup reductions were only found in three industry groups (mining and quarrying, wholesale and retail trade; financial services and real estate). At the more disaggregate level, the picture is mixed: Both increases and reductions in market power have been found. 相似文献

出口开放、地区市场规模和经济增长 总被引:40,自引:1,他引:40
报酬递增是跨国或区域经济增长发散的重要动因,而市场范围的大小则决定了报酬递增的程度。本文的实证研究发现,地区市场规模和出口开放程度显著地影响了1970—2000年各省区人均收入的增长速度;在地区差距的形成和演进过程中,国外和地区市场是相互替代的,而一旦控制了市场规模因素,各个省区即呈现明显的收敛趋势。本文根据地理特征构造工具变量,有效地控制了变量的内生性问题。 相似文献
