CEO's Operating Ability and the Association between Accruals and Future Cash Flows

This study investigates whether an individual CEO's operating ability, operationalized as the extent to which an individual CEO utilizes the company's assets efficiently to generate profits, explains the association between accruals and future cash flows. While this mapping can be driven by both the quality of accounting measurement and CEO operating ability, there is little empirical evidence on the latter link. After controlling for the CEO's accounting estimation ability, we find that the association between current period accruals and future cash flows is stronger when the CEO demonstrates superior operating ability. This suggests that a CEO's operating ability is an important determinant of the informativeness of current accruals for future cash flows.

Does Korea follow Japan in foreign aid? Relationships between aid and foreign investment

Korea, an emerging donor country, largely considers its economic relations to recipients when allocating its aid. Such practices were preceded by Japan before the 1990s. We expect those similar practices between the two countries will make resemblance in aid outcomes. On a macro-level, we show similarities in aid allocations by type, region, income, and sector. The similarities are ascertained also at a micro-level by our statistical analysis on the relationships between aid and FDI. The analysis based on the FDI gravity model and panel dynamic system GMM estimation shows that only aids from Korea and Japan create more inflow of FDI into their respective recipient developing countries. Those are contrasted with other donors’ aids, which are not related to FDI or the substitute for FDI.

Profit-Volume-Exchange-Rate Analysis for Planning International Operations

We extend the conventional Profit-Volume (P-V) analysis to develop a new model of Profit-Exchange-Rate (P-ER) analysis to evaluate how exchange rate fluctuations impact profit. We begin by classifying costs as either "global cost" or "local cost" according to whether or not input prices are exchange-rate sensitive. This classification is analogous to the familiar variable/fixed cost classification based on the cost sensitivity to volume change. Data for the U.S. and Japanese steel industries are used to illustrate the approach. We then combine the conventional Profit-Volume analysis with the Profit-Exchange-Rate analysis to form a composite model, called Profit-Volume-Exchange-Rate (P-VER) analysis, where both volume and exchange rate vary. We show that this composite approach suggests the use of a single rate-volume variable, similar to "person-hours," as the key planning-control variable for international operations.     

Income Inequality and Economic Progress

A bstract . The institutionalist approach to income distribution and economic progress is compared to the conventional approaches such as neo classical and neo-Keynesian schools. A two step causal model reflecting the institutionalist view on the relationship of these two variables is constructed. The empirical results show that the greater the inequality in the distribution of personal incomes, the greater the level of socio- political instability , and that the greater the level of socio-political instability, the slower the economic progress.     

计时工资函数与最优工资定价模型

本文运用微观经济学中效用函数的理论,讨论了雇员工资函数的分析性表达式,并给出了一个满足所给条件的数学描述。然后应用X2分布描述了加班时实际工作时间的分布,得出了工资产出效率,以此作为工资定价的评价标准,导出了最优工资定价方案满足的优化模型。本文的结论对于制定合理的工资政策,提高资金的使用效率有较大的指导意义。     

论网络体育新闻报道的特点

21世纪以来，网络体育新闻报道作为一种新型的体育新闻报道方式得到了迅猛发展。这种新闻报道方式有着时效性强、信息表现形式多样化、受众参与互动性强、信息海量性等优点．但也存在新闻造假、忽视对新闻内容的选择和忽视新闻内容自身价值等缺陷。因此．这种新闻报道方式应充分发挥优势，努力克服自身缺陷，并进一步强化新闻从业人员的专业素养和社会责任意识．以便更好地为公众提供信息服务。
