This paper addresses the supply-side explanations of a logger shortage by estimating an occupational choice model that considers the role of earnings, nonpecuniary determinants and intergenerational factors. Our results showed that: (1) relative earnings have no statistically significant effect on career choice; (2) improvement in the public image of loggers substantially increases entry into logging; and (3) a strong intergenerational supply linkage exists but is currently being eroded. 相似文献

针对物流系统设计,基于网络规划法提出了一种在物流中心已经确定的条件下,进行道路系统的新的设计方法。通过合理但设把道路系统的设计转变为网络规划中求解最短路径的问题.通过统计每个路段的最短路径通过率.得出路段的运量负担情况,从而为道路的功能和等级设计提供依据。在此基础上.以宁波化工区的物流系统为例,建立了宁波化工区道路系统的网络模型,对宁波化工区的道路系统进行了功能设计。结果表明,该方法在区域物流系统设计中有良好的应用前景. 相似文献

Increasing the inflation target in a New Keynesian (NK) model may require increasing, rather than decreasing, the nominal interest rate in the short run. We refer to this positive short‐run comovement between the nominal rates and inflation conditional on a nominal shock as Neo‐Fisherianism. We show that the NK model is more likely to be Neo‐Fisherian the more persistent is the change in the inflation target and the more flexible are prices. Neo‐Fisherianism is driven by the forward‐looking nature of the model. Modifications that make the framework less forward‐looking make it less likely for the model to exhibit Neo‐Fisherianism. 相似文献

We study temporary fiscal stimulus designed to support distressed housing markets by inducing demand from buyers in the private market. Using difference-in-differences and regression kink research designs, we find that the First-Time Homebuyer Credit increased home sales by 490,000 (9.8%), median home prices by $2,400 (1.1%) per standard deviation increase in program exposure, and the transition rate into homeownership by 53%. The policy response did not reverse immediately. Instead, demand comes from several years in the future: induced buyers were three years younger in 2009 than typical first-time buyers. The program's market-stabilizing benefits likely exceeded its direct stimulus effects. 相似文献

Price reviews are a potentially costly activity. A significant fraction of unchanged prices may stem from firms not reviewing prices, rather than from obstacles to changing prices per se, such as menu costs. In this paper, we disentangle these two causes of price stickiness by estimating an inflated ordered probit model on a panel of French manufacturing firms. The results point to a low frequency of price reviews, suggestive of the relevance of information costs as a determinant of the observed price stickiness. In view of the “inattentive producers” literature, pointing that the source of price rigidity matters, this is suggestive of a large real effect of monetary policy. 相似文献

In this paper, we estimate the language effects on the earnings distribution among child immigrants. Utilizing U.S. Census data, we find: (1) there exists a larger heterogeneity in language premiums across the earnings distribution, and the patterns change over time (2) occupation and education channels explain most of the language effects and the large heterogeneity in them. However, the importance of these two channels has decreased over time. 相似文献
