Unemployment insurance benefits and income smoothing

Labor unemployment insurance reduces unemployment concerns. We argue that these benefits moderate incentives to smooth earnings to reduce employees’ concerns about unemployment risk. Using exogenous variations in unemployment insurance benefits, we find evidence consistent with this argument. We also find that the link between unemployment insurance benefits and income smoothing is stronger when there is higher unemployment risk and when the firm is likely to employ more low-wage workers, who find unemployment insurance benefits especially useful. Our paper contributes to the literature by showing that public policy decisions such as unemployment insurance have significant, albeit probably unintended, externalities on corporate financial reporting.

Economic policy uncertainty and stock price crash risk

This paper studies the impact of economic policy uncertainty on stock price crash risk using data from China. We develop a new index to measure Chinese economic policy uncertainty and find that economic policy uncertainty has a remarkable positive effect on stock price crash risk. However, the effect reverses later. The results also indicate that the positive effect of economic policy uncertainty on stock price crash risk is more prominent for state‐owned enterprises. Moreover, this effect is more prominent for firms with higher information asymmetry and firms with greater disagreement among investors, indicating that economic policy uncertainty affects crash risk through two mechanisms: managers’ concealment of bad news and investors’ heterogeneous beliefs.

我国生猪养殖户饲料需求行为分析——基于对辽宁、河北生猪养殖户的问卷调查

本文以对辽宁、河北两省生猪养殖户饲料使用情况的调研数据为基础,从养殖户饲料需求的总体情况、养殖户的不同养殖规模、养殖户的不同兼业程度3个角度分别对我国生猪养殖户的饲料需求行为进行分析。结果表明:调研两省生猪养殖户的工业饲料使用比重不高、饲料粮使用比重较高、农副产品使用比重差异较大,这主要是受生猪养殖的规模化水平、饲料价格以及当地资源条件等因素的限制。     

A NEW THEORY OF DEMAND AND SUPPLY AND EMERGENCE OF INTERNATIONAL TRADE FROM DOMESTIC TRADE

Abstract. In the paper a fixed learning cost is introduced into a framework with consumer-producers and transaction costs. The fixed learning cost yields a rate of return on the investment in individual specific learning and training which is increasing in its rate of utilization. Division of labor can avoid duplicated learning costs and generate economies of specialized learning. The tradeoff between economies of specialization and transaction costs can be used to explain concurrent increases in the extent of the market, aggregate demand, productivity, trade dependence, the degree of market integration, the degree of production concentration, diversity of economic structure, variety of different professions, each person's level of specialization, and the extent of endogenous comparative advantage and the emergence of international trade from domestic trade. This model explains demand and supply as two sides of the level of division of labor which is determined by a transaction cost coefficient. Hence, the demand law may not hold even for normal goods owing to complicated interdependencies between the level of specialization and demand and between the level of specialization and prices of traded goods. The extended version of this model with the CES function is used to endogenize variety of consumption in addition to the endogenization of individuals'level of specialization.
