We study price discovery in municipal bonds, an important OTC market. As in markets for consumer goods, prices “rise faster than they fall.” Round‐trip profits to dealers on retail trades increase in rising markets but do not decrease in falling markets. Further, effective half‐spreads increase or decrease more when movements in fundamentals favor dealers. Yield spreads relative to Treasuries also adjust with asymmetric speed in rising and falling markets. Finally, intraday price dispersion is asymmetric in rising and falling markets, as consumer search theory would predict. 相似文献

In small groups, norm enforcement is achieved through mutual punishment and reward. In large societies, norms are enforced by specialists such as government officials. However, not every public cause is overseen by states, for instance those organized at the international level. This paper shows how nongovernmental norm enforcement can emerge as a decentralized equilibrium. As a first stage, individuals voluntarily contribute to a nongovernmental agency that produces an incentive system. The second stage is the provision of a public good on the basis of private contributions. The incentive system increases contributions by means of public approval or disapproval of behavior. It is shown that, even in large populations, nongovernmental norm enforcement can be supported in a noncooperative equilibrium of utility‐maximizing individuals. This result is in sharp contrast to those obtained in the standard situation of voluntary provision of an intrinsic public good which—without altruism or related motives—is eroded by free‐riding. Reliance on altruistic behavior is not required in supplying the second‐order public good “norm enforcement” in large societies. 相似文献

文化产业本身既蕴含新兴产业又包含传统业态,这种特征决定了其未来增长路径的复杂性。产业集聚程度是产业效率的重要影响因素,产业效率是产业竞争力的重要体现,而文化产业的集聚效应表现尤为突出。理清文化产业集聚程度与文化产业发展效率之间的作用机理,有助于促进区域文化产业的发展和竞争实力的提升,对促进区域文化产业的发展效率提升具有重要的现实意义。因此,文章基于2011—2018年中国31个省(自治区、直辖市)的面板数据,关注文化产业发展过程中存在产业集聚以及空间、时间上的相关性,构建时空随机前沿模型进行技术效率测算。研究发现:2011—2018年全国文化产业技术效率呈整体下降趋势,空间交互作用及产业集聚对文化产业发展有促进作用,但文化产业表现出明显的惯性,影响了增长动能的传递;融资环境、市场环境、技术环境、制度环境对文化产业技术效率也存在显著影响。 相似文献

This paper answers the question of what would have been the growth rate of aggregate productivity in Turkey between 2002 and 2007, had it realized China’s rates of productivity growth in agriculture, industry, and services. It does this in a three-sector general equilibrium model calibrated to the Turkish economy over the 2002–2007 period. The main findings are: (i) Turkey would have had much higher aggregate productivity growth over this period if it had experienced China’s service sector productivity growth; (ii) very low productivity growth rates in finance and in the non-market service sector are the main culprits behind Turkey’s weak service-sector performance. 相似文献

We develop a dynamic tradeoff model to examine the importance of manager–shareholder conflicts in capital structure choice. In the model, firms face taxation, refinancing costs, and liquidation costs. Managers own a fraction of the firms’ equity, capture part of the free cash flow to equity as private benefits, and have control over financing decisions. Using data on leverage choices and the model's predictions for different statistical moments of leverage, we find that agency costs of 1.5% of equity value on average are sufficient to resolve the low‐leverage puzzle and to explain the dynamics of leverage ratios. Our estimates also reveal that agency costs vary significantly across firms and correlate with commonly used proxies for corporate governance. 相似文献

This paper proposes a mechanism for the regulation of duopolies a revenue contests among the firms. Under the mechanism, the
firm with the lower revenue is to pay a penalty to the firm with the higher revenue proportional to the difference between
their revenues. In a homogenous good Cournot duopoly with convex cost and demand functions, the mechanism implements the optimal
outcome when the firms have symmetric costs. When one firm is more efficient, the mechanism leads to increased social surplus
under a large set of parameters. We also consider extensions that involve cost uncertainty, repeated games and differentiated
goods. 相似文献
