Regulation of Mobile Telephony across the European Union: An Empirical Analysis

In this paper I analyze the impact of regulatory policy on prices and demand for mobile telecommunications services across the European Union. I estimate a reduced form model of the mobile industry using panel data for the EU countries from 1998 to 2002. Among others, I find the following effects: liberalization of fixed telephone lines has a negative impact on prices and a positive impact on the demand for mobile services, and the introduction of mobile number portability has a negative impact on prices.*I am grateful to Toker Doganoglu, Gerd Hansen, Eric Kodjo Ralph, Guido Friebel, participants at the 30th EARIE Conference 2003, the 2nd International Industrial Organization Conference 2004 and the 19th Annual Congress of the EEA 2004, and anonymous referees for valuable comments.

领导风格与员工工作态度——互惠和信任的中介作用的实证研究

互惠和信任是社会交换的普适准则。本文基于社会交换理论，以中国境内各类企业972位管理人员为样本，试图研究领导风格与员工工作态度之间的关系，尤其是组织与员工间的互惠和员工的组织信任在其中的中介作用。在初步研究的基础上，本文对变革型领导、事务型领导、广义互惠、平衡互惠、员工的组织信任、组织承诺和离职意愿各概念进行了系统的探索性分析和验证性分析，接着检验了这七个核心概念的区分效度。研究结论表明：（1）变革型领导不仅直接对员工的组织信任和组织承诺产生作用，而且通过组织对员工的广义和平衡互惠使员工产生对组织的信任，从而提高员工的组织承诺和降低员工的离职意愿；（2）事务型领导仅仅通过互惠对员工的组织信任和组织承诺产生作用；（3）广义互惠直接影响员工的组织承诺，平衡互惠通过组织信任影响员工的组织承诺。研究结论告诉我国企业领导者，首先，尽可能锻炼自己，努力成为变革型领导者。其次，要努力塑造互惠和信任的企业文化，并且特别着重于建设广义互惠的企业文化和制度环境。     

Trees and decisions

Summary. The traditional model of sequential decision making, for instance, in extensive form games, is a tree. Most texts define a tree as a connected directed graph without loops and a distinguished node, called the root. But an abstract graph is not a domain for decision theory. Decision theory perceives of acts as functions from states to consequences. Sequential decisions, accordingly, get conceptualized by mappings from sets of states to sets of consequences. Thus, the question arises whether a natural definition of a tree can be given, where nodes are sets of states. We show that, indeed, trees can be defined as specific collections of sets. Without loss of generality the elements of these sets can be interpreted as representing plays. Therefore, the elements can serve as states and consequences at the same time.Received: 23 January 2003, Revised: 2 November 2003, JEL Classification Numbers: C72, D70.

The effects of internal and external sources of justice on employee turnover intention and organizational citizenship behavior toward clients and workgroup members

Abstract

Organizational justice research tends to focus on the effects of fair treatment from organizations or supervisors on employee attitudes and behaviors. Thus, there is a dearth of research on the effects of fair treatment attributable to other parties that employees interact with at work such as coworkers and clients. Controlling for organization-focused and supervisor-focused justice, results from our field study of employees working in a healthcare organization demonstrate that perceptions of client-focused fairness uniquely predicts supervisor ratings of employees organizational citizenship behavior toward clients and that perceptions of workgroup-focused justice uniquely predicts organizational citizenship behavior toward workgroups. Further, we find that client-focused justice perceptions uniquely predict employee turnover intention.     

External cooperation and entrepreneurial orientation in industrial clusters

ABSTRACT

The aim of this paper is to examine the relationship between external cooperation and entrepreneurial orientation (EO). This relationship is explored in cluster environment, wherein entrepreneurial organizations compete and cooperate simultaneously to pursue opportunities. The following hypothesis is tested: External cooperation is positively correlated with entrepreneurial orientation. The hypothesis is tested with a correlation analysis on a sample of 77 small-sized enterprises operating in the Malopolska region in Poland, wherein several clusters are active. Additionally, the regression analysis is conducted to examine the associations between inter-organizational cooperation and EO dimensions. The findings confirm that external cooperation is positively correlated with EO. This observation is confronted with a pro-competitive approach that is a constitutional element of the entrepreneurship concept. Moreover, the findings show that the correlation between external cooperation and a firm’s performance is stronger than between some other EO dimensions and performance. Additionally, the findings show the important role of relationships between organizations and their clients. In the paper, several remarks for development of the theory are discussed, including the need for incorporating inter-organizational cooperation into a set of entrepreneurial traits and reflecting it in entrepreneurial orientation scales. The findings confirm the importance of that direction of theory development that focuses on inter-organizational collaboration in the context of entrepreneurship.     

Introduction to the special issue on positive conflict—Conflict and employees: The right and processes to be heard

Conflict, defined as clash, competition, or mutual interference of opposing or incompatible forces or qualities, may be positive. The appropriate amount of conflict may be a delicate balance not easily achieved. Thus, a key issue is conflict management. The major charter of this special issue is the presentation of work which suggests or demonstrates that conflict can be a positive force in the modern organization. It also is pointed out that conflict, positive or otherwise, and its resolution involves a broad spectrum of inquiry into the rights and obligations of those involved in the conflict     

A theory of sequential reciprocity

Many experimental studies indicate that people are motivated by reciprocity. Rabin [Amer. Econ. Rev. 83 (1993) 1281] develops techniques for incorporating such concerns into game theory and economics. His theory is developed for normal form games, and he abstracts from information about the sequential structure of a strategic situation. We develop a theory of reciprocity for extensive games in which the sequential structure of a strategic situation is made explicit, and propose a new solution concept—sequential reciprocity equilibrium—for which we prove an equilibrium existence result. The model is applied in several examples, and it is shown that it captures very well the intuitive meaning of reciprocity as well as certain qualitative features of experimental evidence.     

新会计准则对上市公司信息披露的影响分析

本文在回顾我国会计准则变迁以及概括新准则主要变化的基础上,从内容和形式两个方面研究了新准则对上市公司信息披露的影响。认为新准则对信息披露的影响主要表现在财务报告的构成方面,财务报告的组成及其格式都发生了较大的变化。这些形式和内容上的变化使得新会计准则对上市公司的信息披露提出了更高的要求,上市公司信息披露的逐步完善将有助于投资者做出更准确的投资决策,降低投资风险,必将提高上市公司财务报告的使用价值,增强上市公司业绩的可预测性。     

组织激励资源运用的效率分析

本文从企业组织整体目标利益角度出发，将组织激励资源作为稀缺性资源，探讨了组织内部员工的激励问题，同时借助经济学关于资源有效配置的理论，以及组织行为学中的公平激励理论，对组织激励经济资源运用的有效性，以及相关的影响因素进行了探讨，并在此基础上提出了组织一定经济激励资源量获得最大组织激励动力的条件，以及组织获得最大经济激励资源运用绩效效率水平的条件或原则。     

不要混同"公有制形式"和"公有制实现形式"

近年来，出现了将我国公有制形式与公有制实现形式混同的情况，这在理论和实践上都站不住脚。股份制“姓公”或“姓资”关键要看控股权掌握在谁手里。对于理论界和媒体对马克思著作和中央有关理论指导的误解，需要引起重视，有必要澄清理论是非，以避免理论误导可能产生的多种混乱和消极后果。
