Assessing effects of federal crop insurance supply on acreage and yield of specialty crops

Crop insurance may affect harvested acreage and yield by influencing producers’ behavior such as land allocation and input use. Although specialty crops are a major source of farm income, especially on the U.S. west coast, they have not received as much attention as field crops in previous empirical studies. This paper assesses the effect of moral hazard and adverse selection associated with the federal crop insurance program (FCIP) on the acreage and yield of major specialty crops in California. An econometric method that expands the switching regression model is developed to assess the effect. Results suggest that federal crop insurance can change specialty crop growers’ production responses to climate and soil conditions. The moral hazard effect tends to increase the acreage and yield of the specialty crops, whereas the adverse selection effect tends to have the opposite effect. The overall effect of the FCIP on acreage and yield of specialty crops is found to be moderate.

IFRS Adoption and Stock Prices of Japanese Firms in Governance System Transition

This study examines firms' decision to voluntarily adopt IFRS in a setting where there are changes to the governance system in a traditionally code law country, as well as how the market responds to such decisions. We find the probability of voluntary IFRS adoption to be higher among firms that have a high proportion of foreign shareholders, undertake quality audits, have low levels of leverage, feature a nominating committee, and are included in the new market index. In addition, the stock prices of IFRS adopters tend to increase around the announcement date of IFRS adoption, compared to those of non-adopters. Finally, market reactions are smaller for firms that feature a nominating committee, and are included in the new market index—perhaps because IFRS adoption by these firms is less surprising to market participants, and because IFRS adoption is not expected to add large incremental value to these firms.     

高管同酬、激励效率与公司绩效

我国部分上市公司的董事长和总经理领取的年薪完全相同。这种高管同酬的确定依据是什么？高管同酬是否具有激励效率？高管同酬又会对公司绩效产生什么影响？文章利用2007－2012年 A 股上市公司数据,对高管同酬及其经济后果进行了实证分析。研究发现,部分上市公司出现高管同酬,主要是因为高管薪酬由公司政治因素或内部薪酬比较所决定,而并非遵循最优契约观所寓示的“效率逻辑”;与高管异酬的公司相比,高管同酬公司的董事长薪酬激励缺乏效率;高管同酬对公司未来财务绩效产生了显著的负面影响。这表明在中国情境下,高管薪酬契约的设计和实施需要关注公司权力博弈或内部薪酬比较等非经济性因素的影响。
