Religion, longevity, and cooperation: The case of the craft guild

When the mortality rate is high, repeated interaction alone may not sustain cooperation, and religion may play an important role in shaping economic institutions. This insight explains why during the fourteenth century, when plagues decimated populations and the church promoted the doctrine of purgatory, guilds that bundled together religious and occupational activities dominated manufacturing and commerce. During the sixteenth century, the disease environment eased, and the Reformation dispelled the doctrine of purgatory, necessitating the development of new methods of organizing industry. The logic underlying this conclusion has implications for the study of institutions, economics, and religion throughout history and in the developing world today.     

基于自由现金流量假说的盈余管理动因研究——来自中国上市公司的经验证据

基于代理成本理论及自由现金流量假说分析框架,研究了我国上市公司自由现金流量引发的盈余管理行为,并以2004~2006年我国A股上市公司为样本,运用面板数据分析方法进行了相应的实证研究。研究发现,自由现金流的代理成本是激发我国上市公司管理者进行盈余管理的重要原因;企业债务对自由现金流引发的盈余管理行为具有一定的抑制作用,但债务的软约束现象仍然存在。

The Incredible Economics of Geoengineering

The focus of climate policy so far has been on reducing the accumulation of greenhouse gases. That approach, however, requires broad international cooperation and, being expensive, has been hindered by free riding; so far, little action has been taken. An alternative approach is to counteract climate change by reducing the amount of solar radiation that strikes the Earth—“geoengineering.” In contrast to emission reductions, this approach is inexpensive and can be undertaken by a single country, unilaterally. But geoengineering also has worrying consequences: it may harm some countries; it would not address ocean acidification; it would pose new risks. The fundamental challenge posed by this new technology is not free riding but governance: who should decide if and under what circumstances geoengineering should be used?     

"新新贸易理论"的思想脉络及其发展

新新贸易理论将企业异质性成功的引入到国际贸易模型中,从微观层面解释了贸易的发生及影响,从而开拓了国际贸易研究的新领域。新新贸易理论解释了为什么好的企业做国际贸易,而较次的企业做国内贸易这一现象,该理论认为,自由贸易可以提高产业生产率水平和社会福利,所以在政策上应该促进自由贸易而不是贸易保护。     

Domestic entry, optimum-welfare and maximum-revenue tariffs

In this paper, we examine the ranking of the maximum-revenue tariff and the optimum-welfare tariff under a linear Cournot oligopoly model without and with free entry of domestic firms. We demonstrate that in a regulated entry oligopoly with asymmetric costs, when the marginal cost of the domestic firms exceeds a critical value, the maximum-revenue tariff is higher than the optimum-welfare tariff. We then show that under free entry of domestic firms with asymmetric costs, when the fixed cost gets larger and the domestic firms become fewer, the difference between the optimum-welfare tariff and the maximum-revenue tariff becomes larger.     

金融监管法的价值:自由竞争与金融安全

分析美国金融法的历史可以看到,金融监管法的核心价值由完全的自由竞争变为单一的金融安全,再转向有安全保障的自由竞争;分析金融法律规范也可以证实,现行的金融监管目标与各种监管措施都体现自由竞争与金融安全的价值追求.过分追求金融安全的价值观是非常局限的,它只能适用于金融不安全的状况;现在的金融效率观不是金融监管法的价值观.自由竞争与金融安全是对立统一的关系,两者的地位随着金融运行态势的变化而逐步变化.     

中日韩自由贸易区的贸易流量和福利效应分析:一个局部均衡的校准方法

校准方法作为一种确定数理经济模型中的变量和参数的手段之一,在贸易政策的建模研究中得到广泛的应用.本文以局部均衡为基础,利用中日韩三国自1990～2003年共14年的贸易额及相关数据建立校准模型,并对拟议中的中日韩自由贸易区做出比较静态分析,从产业层面来模拟中日韩自由贸易区建成后所可能带来的福利效应.分析结果表明,中日韩三国建立自由贸易区会增加彼此的国民福利水平,并会对未加入贸易协定的其他东亚国家产生影响.因此,在东亚形成更为广泛的自由贸易安排从区域合作的角度来看是一种更佳的合作方式.
