Production-location decision and free entry oligopoly: A correction

This paper shows that there is no interior solution in Mai–Hwang's 1992 oligopolistic location model with free entry when the production function exhibits constant or decreasing returns to scale. The comparative static results of the impact of a demand change on the location decision only apply to the case where the production function exhibits increasing returns to scale. It re-examines the impact of a demand change on the location decision of an oligopolistic firm and corrects the propositions derived by [C.C. Mai, H. Hwang, Production-location decision and free entry oligopoly, Journal of Urban Economics 33 (1992) 252–271. Reprinted in: M.L. Greenhut, G. Norman (Eds.), The Economics of Location, vol. I: Location Theory, Edward Elgar, Aldershot, 1995].     

Individual rights and organizational theory

Rights are very important concepts in everyday life. And they are especially important to participants in organizations. Yet, our theories of organization and management have largely ignored rights — stressing, instead, other concepts, such as goals, roles, etc. This article describes the historical significance of rights and their relevance in understanding social behavior. The advantages of a right-based organizational theory (versus traditional goal-based theories) are discussed.This article draws on the author's forthcoming book,A Social-Contract Theory of Organizations (University of Notre Dame Press, 1988).     

The impact of the WARN Act on firm value

The Worker Adjustment and Retraining Notification (WARN) Act of 1989 mandated that at least 60 days advance notice be given to employees. Critics argued that its passage would decrease managerial flexibility in closing plants, subsequently reducing firm values. This study addresses this issue by examining the stock market's reaction to announcements leading to the eventual enactment of the WARN legislation. We find evidence indicating negative effects of the legislation on stock returns of small firms.     

Anchor stores

Planned shopping malls usually have one or more department (anchor) stores and multiple specialized retailers selling substitutable commodities in each commodity category. If consumers know their taste for the anchor's commodity and its price, but learn about a retailer's commodity only by costly search, collocation may benefit both store types. Intra-mall competition reduces markups, but anchors guarantee a minimum surplus from search. A mall with many retailers makes finding a suitable specialized commodity highly probable. For some parameters, additional consumer search dominates the loss in retail markups, so a profit-maximizing land developer would rent mall space to both store types.

Does subsidised temporary employment get the unemployed back to work? Aneconometric analysis of two different schemes

Subsidised employment is an important tool of active labour market policies to improve the reemployment chances of the unemployed. Using unusually informative individual data from administrative records, we investigate the effects of two different schemes of subsidised temporary employment implemented in Switzerland: non-profit employment programmes (EP) and a subsidy for temporary jobs (TEMP) in private and public firms. Econometric matching methods show that TEMP is more successful than EP in getting the unemployed back to work. Compared to not participating in any programme, EP and TEMP are ineffective for unemployed who find jobs easily anyway or have a short unemployment spell. For potential and actual long-term unemployed, both programmes may have positive effects, but the effect of TEMP is larger.     

农业价值负功能现象的探索

农业价值中普遍存在负功能的现象。其特征是:负功能与正功能互为依存、互为转化,依据不同时间、社会、自然、经济条件而变化,有的事物本身既有正功能,又不可避免地具有负功能,负功能成为事物固有功能的一部分,并对总功能产生影响。研究负功能,有利于防止、克服和转化负功能对事物价值的影响,保持农业可持续发展。     

BEYOND THE HYPE: INTELLECTUAL PROPERTY AND THE KNOWLEDGE SOCIETY/KNOWLEDGE ECONOMY

Abstract.  This paper explores the debates surrounding whether or not we have now moved into a new knowledge economy and/or knowledge society and if so whether this shift is as significant and as far reaching as the industrial revolution. In this possible transformation the place of information communications technologies has been crucial. Debate has occurred across both economics and sociology with differing emphases as is shown in the ranges of definitions that we review in the paper. One consistent factor is the lack of clarity and consistency between them both within and across the disciplines. In order to explore the issues that the debates raises in a more grounded way, the paper explores them in relation to intellectual property (IP) and the intellectual commons in the process of innovation, growth and economic development. The paper is developed through an analysis first of the industrial revolution and the role within this of uncertainty, technologies, complementarities and elective affinities and the way IP was protected and controlled through patents, secrecy, being first to the market and copyright. The second part of the paper examines definitions of the knowledge economy and society and the role within these of information communication technologies in order to explore whether the ways that IP is protected and controlled have changed. In the debate about the 'knowledge economy and society' the role of innovation via human capital with a greater reliance on intellectual capabilities has been emphasized. The role of IP thus remains central but is now challenged by the rise of new forms of communication, which make its protection harder and move much of the concern with respect to regulation to a global rather than national and local level.
