Can intertemporal choice experiments elicit time preferences for consumption?

The paper considers what can be inferred about experimental subjects’ time preferences for consumption from responses to laboratory tasks involving tradeoffs between sums of money at different dates, if subjects can reschedule consumption spending relative to income in external capital markets. It distinguishes three approaches identifiable in the literature: the straightforward view; the separation view; and the censored data view. It shows that none of these is fully satisfactory and discusses the resulting implications for intertemporal decision-making experiments. JEL Classification C90, C91, D90, D91, D11, D12     

和合管理的价值观体系

任何一种社会科学的理论体系,都要求有一定的价值观为指导。传统的和合理念为什么能够经久不衰？因为和合理念是中华民族深厚历史文化的结晶,符合经济社会发展的需要。和合管理为什么能够支撑中国封建社会数千年的持续发展？因为和合管理不仅有着现实的适应性,而且还在于理论上有着正确的价值观基础。本研究揭示,以人为本与和合理念是和合管理特有的叠生价值观体系。以人为本与和合理念的有机组合,是和合管理与时俱进的生命力源泉。     

A comparison of programming languages in macroeconomics

We solve the stochastic neoclassical growth model, the workhorse of modern macroeconomics, using C++14, Fortran 2008, Java, Julia, Python, Matlab, Mathematica, and R. We implement the same algorithm, value function iteration, in each of the languages. We report the execution times of the codes in a Mac and in a Windows computer and briefly comment on the strengths and weaknesses of each language.     

The relationship between employee performance management and civil servants’ turnover intentions: a test of the mediating roles of system satisfaction and affective commitment

In search of maximizing efficiency, public organizations found solace in the adoption of employee performance management (EPM) systems. While research supports that managing employees’ performance has favourable outcomes, it is still unclear why and under which conditions. Moreover, EPM systems might even create additional pressures and therefore increase turnover intentions and undermine public organization’s quest to maximize efficiency. We argue that when EPM systems are carried out consistently (i.e. internal consistency) and when they link civil servants’ individual goals to the organization’s strategic goals (i.e. vertical alignment), civil servants will be less likely to leave the organization. Hierarchical linear regression analysis shows that internal consistency relates to increased satisfaction with the EPM system and affective commitment to the organization. Vertical alignment relates to lower levels of turnover intentions. This relationship was mediated by EPM system satisfaction and affective commitment. These findings that contribute to our understanding of EPM systems can lead to favourable outcomes.

基于JIT思想对汽车玻璃生产线WIP的控制策略

本文分析了汽车玻璃加工生产线的生产流程,生产车间不同种类的在制品(WIP)数量很庞大,为此研究生产线的瓶颈工序,得到瓶颈工序生产线的切换时间对WIP库存的影响,研究生产线的切换时间、工序之间的生产节拍比和WIP库存数三者之间的关系,结合JIT和WIP库存控制策略来保证生产线的流畅生产,归纳出关键的工序节拍比下所需的WIP库存数的动态变化情况,从而动态地控制WIP库存的变化并最大程度地降低车间的WIP库存。
