Dimand-Dore on cournot-bertrand: A reply and more

This note refutes the novel thesis of Jean Magnan de Bornier [1992] that all of Cournot's analysis in his 1838 classic was about price rivalry. It also reiterates the proposition that Cournot treated both quantity and price rivalry and that Cournot was clearly aware of the symmetry between quantity conjectures and price conjectures in 1838. It is conjectured that the many misinterpretations of Cournot derive from failure to work through Cournot's simple mathematics and a mental truncation of the Recherches into just Chapter VII.     

Software to support business teams

Organizations are increasingly using the business team concept to gain competitive advantage. Collaboration support software is gaining acceptance as a viable tool among both researchers and practitioners, and an opportunity exists to investigate the specific needs of teams: users working in longitudinal time frames on a variety of tasks. In this article, team software requirements are first derived from a theoretical perspective: office automation and task literature are used to identify a set of domain-independent individual tasks. Group process literature is then used to develop a set of collaborative tasks composed of these individual task components. These individual and collaborative tasks are aggregated with team task and communication support requirements to develop requirements for an integrated software environment that effectively supports business teams. Design considerations for a comprehensive team support system are outlined, a prototype implementation is described, and project contributions and key future research considerations are summarized.     

Dual-route communication of destination websites

To understand the communication route of destination websites, this study employed the elaboration likelihood model (ELM) which is a dual-route, multi-process model of persuasive message processing. That is, this study proposed a theoretical model for the dual-route persuasive process based on ELM, investigated its antecedents and consequences, and identified the moderating effect of involvement. Structural Equation Modeling (SEM) is used to test the validity of the conceptual model. The results indicate that highly involved people are inclined to elaborate on information (central route), while people with low involvement are likely to make judgments based on simple cues (peripheral route). Website design characteristics are an important antecedent of both central and peripheral-route persuasions. Attitudes resulting from careful consideration via the central route are more predictive of conation and behavior (further information searching and travel intentions) than those formed via the peripheral route. The study provides a foundation for further tourism research investigating the Internet as a persuasive tool, and suggests strategies for website designers.     

中国需求带动全球金属回收

过去5年，由于金属价格大涨，全世界范围内爆发了一股金属盗窃浪潮——盗窃目标从教堂屋顶上的铅到下水道的钢质井盖，无所不包。但也正因为废品经销商四处搜罗金属，本轮金属牛市也促使了废弃生锈汽车、农用机器和废弃建筑材料得以回收。     

Economic performance, cost economies and pricing behaviour in the US and Australian meat products industries

The cost and demand structures of meat products industries in the US and Australia from 1970 to 1991 are examined. Scale economies, technical change and trade impacts and output pricing behaviour are evaluated, using short- and long-run input cost and input and output demand elasticities. The greatest technological impacts stem from large-scale economies, which are similar across countries. Unit cost savings from output expansion involve capital investment and materials saving in the long run, although input-specific patterns vary by country. Import competition appears to motivate capital expansion further. Finally, large mark-ups of price over marginal cost are found, which are consistent with low profits as a result of the underlying scale economies.     

The impact of voluntary environmental protection instruments on company environmental performance

In the last decade there has been increasing emphasis on the use of voluntary environmental protection tools such as corporate environmental reporting (CER) and environmental management systems (EMSs). There has been relatively little research, however, on the impact of these tools on the actual environmental performance of companies. This paper presents the findings of a survey of 40 companies operating in Western Australia to determine the extent to which the implementation of two voluntary instruments has influenced company environmental performance. The research considered four questions: To what extent have CER and EMSs influenced the environmental performance of companies operating in Western Australia? What are the characteristics of these influences? How does the influence of EMSs on environmental performance compare to that of CER? Have other external factors concurrently influenced environmental performance? In general, most respondents indicated that EMSs had influenced environmental management practices to some extent. On the other hand, CER was seen more as a public relations exercise and had less impact on company practices compared with EMSs. Other factors that influenced environmental performance included pressure from clients, senior management, the public and regulators; corporate culture; and cost savings.

Structural determinants of government budget deficits in developing countries

The purpose of this study is to examine the possibility that certain structural factors make some developing countries more likely to incur government budget deficits than others. Empirical evidence is provided to support the hypotheses that developing countries are likely to have larger government budget deficits the lower their level of economic development, the greater the degree of government participation in the economy, and the less control exercised over government expenditures. Less convincing support is given for the hypothesis that revenue instability contributes to government budget deficits. An unexpected result of the study is that growth of government revenues is positively related to budget deficits, which leads the author to consider the possibility of a ‘Please effect’.     

Short-run labor productivity in a dynamic model

A classic empirical finding is that the short-run output elasticity of demand is smaller than unity and is less than in the long run. This phenomenon is called ‘short-run increasing returns to labor’ (SRIRL). In this paper we analyze SRIRL using a dynamic factor demand model for variable and quasi-fixed inputs, where the latter incur increasing marginal internal adjustment costs. Speeds of adjustment of quasi-fixed inputs are endogenous and variable, not constant parameters. Labor hoarding is shown to be neither necessary nor sufficient for SRIRL. These results are illustrated empirically using annual U.S. manufacturing data, 1952-71.
