Interdependencies in the Dynamics of Firm Entry and Exit

This paper investigates the interdependence between firm entry and exit from an industrial dynamics perspective. The paper discusses how entry and exit rates in industrial sectors are affected by previous exit and entry rates. Economic theory presents two different approaches to how entry and exit of firms are interrelated, the multiplier effect and the competition effect. This paper intends to investigate which force is the predominant one, for entry and exit patterns, respectively. The empirical analysis is based on data for 25 Swedish manufacturing industries at the 2-digit SIC level, during the period 1991–2000. In the estimation work the study applies a dynamic panel data approach as suggested by Anderson and Hsiao [Journal of the American Statistical Association, 76:598–606, 1981] and Arellano and Bond [Review of Economic Studies, 58(2):277–297, 1991]. With respect to entry, the empirical results support the multiplier effect such that entry stimulates future entry, but also a competition effect such that past exit induces additional entry. With regard to exit, on the other hand, the competition effect rules, implying that previous entry causes subsequent exit and previous exit reduces subsequent exit.

Changing Perceptions and Changing Behavior in Customer Relationships

We formulate a theoretical model in which we postulate that if customers' behavior is perceived as not optimal, customers will adjust this behavior based on their current satisfaction and payment equity. Furthermore, customers will also include new experiences. In our empirical study we particularly investigate customer referrals and the amount of services purchased. Our results show positive effects of current satisfaction and payment equity on referrals, while also changes in satisfaction and payment equity affect customer referrals. With respect to the amount of services purchased, our estimation results reveal a positive significant effect of only changes in satisfaction.

MULTIDIMENSIONAL DYNAMIC RISK MEASURE VIA CONDITIONAL g‐EXPECTATION

This paper deals with multidimensional dynamic risk measures induced by conditional g‐expectations. A notion of multidimensional g‐expectation is proposed to provide a multidimensional version of nonlinear expectations. By a technical result on explicit expressions for the comparison theorem, uniqueness theorem, and viability on a rectangle of solutions to multidimensional backward stochastic differential equations, some necessary and sufficient conditions are given for the constancy, monotonicity, positivity, and translatability properties of multidimensional conditional g‐expectations and multidimensional dynamic risk measures; we prove that a multidimensional dynamic g‐risk measure is nonincreasingly convex if and only if the generator g satisfies a quasi‐monotone increasingly convex condition. A general dual representation is given for the multidimensional dynamic convex g‐risk measure in which the penalty term is expressed more precisely. It is shown that model uncertainty leads to the convexity of risk measures. As to applications, we show how this multidimensional approach can be applied to measure the insolvency risk of a firm with interacting subsidiaries; optimal risk sharing for ‐tolerant g‐risk measures, and risk contribution for coherent g‐risk measures are investigated. Insurance g‐risk measure and other ways to induce g‐risk measures are also studied at the end of the paper.     

互联网商业生态系统动态演化仿真研究——以阿里巴巴为例

文章尝试将商业生态系统理论与互联网相结合，解释互联网商业生态系统内部结构的静态和动态演化过程，从理论上深度探索了互联网商业生态系统内部生态发展的内在机理和运行机制，并运用计算机仿真方法模拟了互联网商业生态系统的内部演化过程。研究发现：互联网生态结构的演化过程经历了萌芽期、成长期、繁殖期、分化期四个主要阶段，商圈发展经历了平台、商家、消费者三主体到平台、商家、消费者、专业服务商、增值服务商五主体的进化过程，并不断进化和繁殖生成新的专业服务商和增值服务商，随之产生新的互联网商业生态系统。最后，文章以阿里巴巴电子商务生态系统为案例从经验上对其内部生态系统的发展和演化构成进行了分析。
