Money and specialization

Summary.  This paper examines the relationship between specialization and the use of money in two versions of the search-theoretic monetary model. The first version establishes a surprising result that specialization is more likely to occur in a barter economy than in a monetary economy. The result is reversed in the second version where a different specification of preferences is adopted to limit the scope of barter. This contrast between the results provides a concrete illustration of the general argument that money encourages specialization only when it enlarges the extent of the market.

The effects of transition on the distribution of income in China

Using two large samples for 1988 and 1995 we decompose the Gini coefficient of household income according to type of income with the purpose of analyzing reasons for the rapid increase of inequality. The results show that the change in relative size of money income and its changed profile are found to be the major processes behind the rapid increase of income inequality in rural China. Changes in housing allocation and an increased number of retirees in combination with higher benefits have made inequality increase in urban China and in China as a whole.

International Borrowing, Specialization, and Unemployment in a Small Open Economy

The authors show that an increase in international borrowing increases specialization and unemployment in a small open economy that is subject to terms‐of‐trade risks. The economy has a production advantage in the export sector. However, the size of the export sector is limited by the available funds. To insure workers against income fluctuations arising from terms‐of‐trade risks, firms in the export sector offer workers a stable wage rate with the possibility of unemployment. An increase in international borrowing increases specialization in the export sector, which leads to higher unemployment when the terms‐of‐trade shock is bad. A state‐contingent price subsidy can reduce unemployment without inefficiently reducing specialization. The results are robust to the introduction of risk‐averse firms.

财产税效率的作用机制考察

仅仅依靠公众从辖区中退出提升财产税效率只有理论上的意义。呼吁是另一种提升效率的手段,它的作用机制需要两个条件:退出的可置信威胁,以及对组织管理者漠视呼吁的行为有一定政治成本。在退出之路可行性不大时,降低呼吁成本,使得下情上达的成本减小,同时增加地方政府官员漠视呼吁的政治成本,把处理公众呼吁的行为方式同地方政府官员的政治前途结合起来,这样才能够使财产税得到现实效率。
