Resistance to Trade Liberalization in Unionized Sector

This paper studies the lobbying against trade liberalization by both a firm and a union in the same industry. We find that the relationship between their political activities depends on the effect of political activity by one on the marginal effectiveness of political activity by the other. We also show that, when they are strongly risk-averse and their political activities are strategic complements, trade liberalization is likely to be successful if business is brisk, the foreign firm's production cost is high or the number of union members is small. However, when they are not strongly risk-averse, these results hold reversely.     

Is the Optimal Labor Income Tax Progressive in a Unionized Economy?*

This paper concerns optimal nonlinear labor income taxation in an economy with union wage setting and endogenous hours of work. The purpose is to study the determinants of tax progression. We show that the optimal degree of progression of the labor income tax depends on the extent to which the government can influence the wage rate via tax policy as well as on its ability to redistribute income across individuals. In addition, the argument for progressive labor income taxation depends on whether hours of work are chosen by the employed themselves or the union.     

Monetary union and the Maastricht inflation criterion: The accession countries*

We model an accession country facing a Maastricht‐type inflation criterion that specifies an inflation ceiling. In addition to deciding whether or not to satisfy this criterion, the country must decide how much costly economic reform to undertake. If the country puts enough weight on the future that it can credibly meet the inflation criterion no matter what the ceiling is, then the inflation criterion benefits the country but lowers reform. If the country puts less weight on the future, then a criterion with a properly chosen inflation ceiling can increase reform. We derive the inflation ceilings that maximize the country's welfare and its reform.     

股份制取代合作制是历史的必然——对中国农村金融制度选择的思考

目前，合作金融在中国遇到了种种困惑，这不是合作金融本身的错。一方面中国从来就没有建立过真正的合作金融；另一方面合作金融与中国当前的经济环境也不相适应。而那种异化了的合作金融既没有存在的必要，也没有存在的可能。股份制取代合作制是一种历史的必然。

Valuation of vulnerable American options with correlated credit risk

This article evaluates vulnerable American options based on the two-point Geske and Johnson method. In accordance with the Martingale approach, we provide analytical pricing formulas for European and multi-exercisable options under risk-neutral measures. Employing Richardson’s extrapolation gets the values of vulnerable American options. To demonstrate the accuracy of our proposed method, we use numerical examples to compare the values of vulnerable American options from our proposed method with the benchmark values from the least-square Monte Carlo simulation method. We also perform sensitivity analyses for vulnerable American options and show how the prices of vulnerable American options vary with the correlation between the underlying assets and the option writer’s assets.      

商业信用:基于企业融资动机的实证研究

商业信用是企业从外部市场进行短期融资的重要组成部分。本文采用我国上市公司2000年至2004年的数据实证研究了商业信用作为企业外部融资方式的决定因素。实证结果发现企业获得的商业信用与企业规模、财务杠杆、销售增长率以及国有股比例呈显著正相关关系．而与短期银行借款比例以厦毛利润率呈显著负相关关系。这些发现表明,在我国目前所处的融资环境下。商业信用已经成为企业的重要融资手段。与银行信贷相比。商业信用具有一定的融资比较优势,作为提供商业信用的企业,对客户的经营状况等信息的了解更有效。     

泡沫经济破灭前后日本银企信用风险管理制度及其功效分析

战后,日本金融体系效仿欧美国家建立起一系列信用风险管理制度。同时,根据市场主导型金融市场的特点,逐步建立起具有自身特点的信用风险管理制度。日本银企信用风险管理制度包括商业银行的内部控制制度、银行风险防御及挽救制度、商业银行外部监管制度。通过对日本银企信用风险管理制度的功效进行剖析,可以看出这一制度存在局限性并与日本的泡沫经济、金融危机、金融效率存在内在关系。

信贷市场不完美，产业转型升级和经济增长

本文提出一个信贷市场不完美情况下产业升级的宏观经济模型,其中信用受限的经济主体可以选择不同类型的产业进行投资,产业类型的异质性体现在投资项目的生产效率、投资规模和信用担保程度。经济主体储蓄量的变化会改变信贷在不同生产效率的产业类型之间的分配,而资本在不同产业类型的组合效应造成不同的经济增长模式,包括从事低效产业的落后经济、从事高效产业的先进经济、从事多种产业的混合经济等。
