The impact of mentoring quality on protégés' organization‐based self‐esteem and proactive behavior: The moderating role of traditionality

Based on self‐consistency theory, this study examined the relationship between mentoring quality as perceived by protégés and protégés' proactive behavior. It focused on the mediating role of organization‐based self‐esteem (OBSE) and the moderating role of traditionality. To examine these relationships, we administrated three‐wave surveys to 237 subordinate–supervisor dyads in a construction enterprise. The results of hierarchical linear modeling demonstrated that (a) mentoring quality and proactive behavior had a positive relationship; (b) OBSE mediated this relationship; and (c) traditionality strengthened both the relationship between mentoring quality and OBSE and the indirect effect of mentoring quality on proactive behavior via OBSE. Our findings have theoretical and practical implications for research on mentoring and proactive behavior.     

Personalized goal-based investing via multi-stage stochastic goal programming

In this paper, we propose a goal-based investment model that is suitable for personalized wealth management. The model only requires a few intuitive inputs such as size of wealth, investment amount, and consumption goals from individual investors. In particular, a priority level can be assigned to each consumption goal and the model provides a holistic solution based on a sequential approach starting with the highest priority. This allows strict prioritization by maximizing the probability of achieving higher priority goals that are not affected by goals with lower priorities. Furthermore, the proposed model is formulated as a linear program that efficiently finds the optimal financial plan. With its simplicity, flexibility, and computational efficiency, the proposed goal-based investment model provides a new framework for automated investment management services.

The Evolution of Health Insurer Costs in Massachusetts, 2010–2012

We analyze the evolution of health insurer costs in Massachusetts between 2010 and 2012, paying particular attention to changes in the composition of enrollees. This was a period in which Health Maintenance Organizations (HMOs) increasingly used physician cost control incentives but Preferred Provider Organizations (PPOs) did not. We show that cost growth and its components cannot be understood without accounting for (1) consumers’ switching between plans, and (2) differences in cost characteristics between new entrants and those leaving the market. New entrants are markedly less costly than those leaving (and their costs fall after their entering year), so cost growth of continuing enrollees in a plan is significantly higher than average per-member cost growth. Relatively high-cost HMO members switch to PPOs while low-cost PPO members switch to HMOs, so the impact of cost control incentives on HMO costs is likely different from their impact on market-wide insurer costs.     

农民对宅基地权利认知及影响因素研究*——以河北省新乐市为例

［目的］通过对河北省新乐市农民在宅基地权力认知及影响因素方面的分析，探究我国农村宅基地制度并提出相关建议。［方法］文章受制度功能可信度理论启发，以河北省新乐市14个行政村为调研对象，探究农民对宅基地相关权利认知情况，同时采用Spearman相关性分析研究影响农民宅基地认知的因素。［结果］调研地自发宅基地流转市场已形成，宅基地制度功能处于社会保障功能向财产功能转变的过渡阶段； 农民对宅基地所有权认知不明晰，但并不影响宅基地市场建立； 在宅基地流转中，农民更关注相互之间信任、村委会保留的记录、流转中形成的“事实产权”； 农民性别、年龄、受教育水平和家庭人口数是影响权利认知的主要因素。［结论］依据制度功能可信度理论充分考虑宅基地制度在现阶段的功能变化，因地制宜； 政府应关注农民的宅基地使用权问题，使其真正成为农民的财产； 应对农村宅基地流转中形成的事实产权逐渐正式化； 应制定年轻人就业帮扶和年长者社会保障等相关政策，避免宅基地流转影响农村社会稳定性。     

Financial Sector Volatility,Banking Market Structure and Exports

This paper assesses the impacts of financial sector volatility and banking market structure on industrial exports. By utilising the specification of Rajan and Zingales (American Economic Review 1998; 88 , 559) on the cross‐country, cross‐industry data from Manova (Journal of International Economics 2008; 76 , 33), we find that financial sector volatility, measured as the standard deviation of the growth of private credit, and banking market structure, measured as the share of the three largest banks’ assets in a country, respectively exert significantly negative and positive impacts on industrial exports, particularly for those industries that are more externally financially dependent. The findings are robust to a variety of kinds of sensitivity analysis and thus lend support to the notion that a more stable and concentrated banking system is important to the exports of those industries that rely more on external finance.     

Consumption and exchange rate uncertainty: Evidence from selected Asian countries

We set out to assess the effects of exchange rate uncertainty on real consumption in selected Asian countries. Consumption influences business cycles, which in turn shape short-run monetary policy decisions. Hence, understanding factors driving consumption is appealing to policymakers. To date, few studies have analysed the effects of uncertainty on consumption. The available ones generally focus on the long-run effects, in spite of the fact that the short-run persistence and adjustments to equilibrium are equally relevant. Our study takes these limitations seriously by distinguishing the short- and long-run effects of exchange rate uncertainty on consumption. Using a flexible dynamic panel data technique that allows long-run effects to be homogeneous and the short-run effects to be heterogeneous, we find that uncertainty impedes consumption in the long run. In the short run, however, the effects are immaterial. This evidence remains robust to the measure of uncertainty, asymmetric uncertainty, inflation and the global financial crisis of 2008. By decomposing uncertainty into its temporary and permanent components, we find that the latter have a stronger effect on consumption in the long run than the former. Although both components demand policy attention, the evidence suggests that policymakers should be more concerned with permanent uncertainty.
