Lags and Leads in Life Satisfaction in Korea: When Gender Matters

Using detailed longitudinal data from the Korean Labor and Income Panel Study (KLIPS) from 1998 to 2008, this paper finds significant gender differences in impacts as well as adaptation patterns to major life and labor market events in Korea. Men remain on a higher happiness level throughout marriage, while women return to their baseline happiness within only two years. Consequently, men suffer more from divorce and the death of a spouse. This marital gender happiness gap is equivalent to a (husband only) increase of annual per capita household income of approximately US$17,800. The study further finds that men suffer more from unemployment. Results are robust to the inclusion of multiple simultaneous events and the use of different estimators.     

Combining forecasts: An application to elections

We summarize the literature on the effectiveness of combining forecasts by assessing the conditions under which combining is most valuable. Using data on the six US presidential elections from 1992 to 2012, we report the reductions in error obtained by averaging forecasts within and across four election forecasting methods: poll projections, expert judgment, quantitative models, and the Iowa Electronic Markets. Across the six elections, the resulting combined forecasts were more accurate than any individual component method, on average. The gains in accuracy from combining increased with the numbers of forecasts used, especially when these forecasts were based on different methods and different data, and in situations involving high levels of uncertainty. Such combining yielded error reductions of between 16% and 59%, compared to the average errors of the individual forecasts. This improvement is substantially greater than the 12% reduction in error that had been reported previously for combining forecasts.     

W. H. Hutt (1899–1988): Free Markets and Social Justice

W.H. Hutt reaffirmed the principles of classical economics and classical liberalism and, by applying them to urgent issues he observed in the world around him, he demonstrated the contemporary relevance of freedom and competitive institutions. A wide‐ranging critique of Keynes was founded upon a classical analysis of the labour market, while his trenchant opposition to apartheid advanced along economic and political paths. Hutt questioned the justice of the accumulation of wealth from the exploitation of monopoly power over generations. In all of these respects there are affinities between Hutt's thought and that of ‘Bleeding Heart Libertarians’.     

Have Employment Relationships in the United States Become Less Stable?

There has been considerable debate as to whether job stability has declined in the United States. This paper uses data from the Survey of Income and Program Participation (SIPP) to examine the incidence of labor market turnover between 1986 and 1993. Specifically, we calculate one- and two-year separation rates and then analyze turnover by the source of separation. We find that the incidence of job separations did not increase over the period under investigation, but appears to have declined somewhat. When analyzing separations by reason, conditional on separating from an employer, we find little evidence of temporal changes in the composition of turnover that would indicate greater employment instability. Therefore, we do not find conclusive evidence that employment relationships have become more unstable in the recent past.      

OCB视角下的派遣员工激励

经济全球化背景下的产业转移升级和企业用工需求的增长,正推动服务外包业务加快进行。特别是在全球金融动荡的经济环境下,将有更多的跨国公司将其非核心业务外包,以降低成本、增强竞争力,这些因素都将推动劳务派遣用工方式的加速进行。因此,派遣员工的规范、管理、激励等问题亟待解决。文章在激励理论和组织公民行为理论的基础上,分析了不同类型派遣员工组织公民行为的分类和特征,提出基于组织公民行为理论的派遣员工激励策略。

Adaptive learning and distributional dynamics in an incomplete markets model

Recent research shows that several DSGE models provide a closer fit to the data under adaptive learning. This paper extends this research by introducing adaptive learning in the model of Krusell and Smith (1998) with uninsurable idiosyncratic risks and aggregate uncertainty. A first contribution of this paper establishes that the equilibrium of this framework is stable under least-squares learning. The second contribution consists of showing that bounded rationality enhances the ability of this model to match the distribution of income in the US. Learning increases significantly the Gini coefficients because of the opposite effects on consumption of the capital-rich and of the capital-poor agent. The third contribution is an empirical exercise that shows that learning can account for increases in the income Gini coefficient of up to 25% in a period of 28 years. Overall, these findings suggest that adaptive learning has important distributional repercussions in this class of models.     

Learning to bid in sequential Dutch auctions

We propose an agent-based computational model to investigate sequential Dutch auctions with particular emphasis on markets for perishable goods and we take as an example wholesale fish markets. Buyers in these markets sell the fish they purchase on a retail market. The paper provides an original model of boundedly rational behavior for wholesale buyers׳ behavior incorporating learning to improve profits, conjectures as to the bids that will be made and fictitious learning. We analyze the dynamics of the aggregate price under different market conditions in order to explain the emergence of market price patterns such as the well-known declining price paradox and the empirically observed fact that the very last transactions in the day may be at a higher price. The proposed behavioral model provides alternative explanations for market price dynamics to those which depend on standard hypotheses such as diminishing marginal profits. Furthermore, agents learn the option value of having the possibility of bidding in later rounds. When confronted with random buyers, such as occasional participants or new entrants, they learn to bid in the optimal way without being conscious of the strategies of the other buyers. When faced with other buyers who are also learning their behavior still displays some of the characteristics learned in the simpler case even though the problem is not analytically tractable.

粮食生产弱质性及其经济效应

现有文献大多是定性地分析粮食生产弱质性的原因,并把弱质性视为粮食生产永恒不变的特性。笔者以相对劳动生产率系数作为粮食生产弱质性的测量指标,计算分析了1978年以来我国粮食生产弱质性程度的变化趋势及其对经济增长和经济结构转变的影响。研究发现,我国粮食生产弱质性程度的长期变化趋势取决于国家经济结构转型战略,局部波动则主要由政府粮食政策的调整引起;粮食生产弱质性程度与粮食生产经济拉动效应中度负相关;粮食生产弱质性与第一产业比重高度负相关,与第二产业比重没有显著线性相关关系,与第三产业比重高度正相关;粮食生产弱质性对我国经济增长和经济结构调整都有较为显著的影响。
