流动人口非正规就业空间竞争:基于上海若干样点的调查

流动人口占有市场空间是个体或利益集团相互竞争、实现市场空间均衡的结果。本文以上海流动人口为研究对象,以非正规就业空间为研究视角,通过分析四类不同性质的非正规就业群体,阐明了流动人口就业空间竞争的基本原理与基本过程,并得出流动人口空间竞争的原动力来源于获利的可能性,空间竞争的过程是空间占有的过程,也是利益均衡的过程。     

Optimal growth and impatience: A phase diagram analysis

When the time preference exhibits decreasing marginal impatience, the rate at which the discount function decreases plays a central role in the stability analysis. This paper shows that if the discount function is strictly decreasing, strictly convex and has a uniform bound on its first derivative, then the continuous-time, one-sector optimal growth problem has a unique steady state that exhibits the saddle-point property. Moreover, the phase diagram analysis is geometrically similar to the case of a constant discount rate. The proposed bounded slope assumption is inspired by and in direct contrast with Magill and Nishimura's "division of countries" example.     

基于自适应控制的区域生态经济协调发展构想

借鉴自适应控制理论的基本思想,建立了包括区域生态经济系统、协调发展评价系统、决策机构及调节系统4大基本要素组成的区域生态经济协调发展总体框架,它具有反馈作用,能根据区域生态经济系统的实际情况自动调节和控制其协调状况,并就此提出了区域生态经济管理的新理念,最后给出相应的建议。

Dissipative Competition: Evidence from a Quasi‐Natural Experiment

We document that contrary to the conventional view, the costs of domestic firms in terms of selling, general and administrative expenses and cost of goods sold increase significantly following exogenous shocks that increase competition, namely material import tariff cuts affecting US manufacturing industries over the period 1974–2005. Incompatible with an agency explanation, the cost increase is more pronounced among firms with higher CEO/insider/board ownership. We further find that the cost increase is more evident among firms with smaller market share and among focused firms. Generally, our results are consistent with the notion of ‘dissipative competition’ discussed in the seminal papers by Tullock.     

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.     

Institutional Monitoring: Evidence from the F‐Score

The extant literature shows that institutional investors engage in corporate governance to enhance a firm's long‐term value. Measuring firm performance using the F‐Score, we examine the persistent monitoring role of institutional investors and identify the financial aspects of a firm that institutional monitoring improves. We find strong evidence that long‐term institutions with large shareholdings consistently improve a firm's F‐Score and that such activity occurs primarily through the enhancement of the firm's operating efficiency. Other institutions reduce a firm's F‐Score. Moreover, we find evidence that, while monitoring institutions improve a firm's financial health, transient (followed by non‐transient) institutions trade on this information.
