Information,market power,and price volatility

We consider demand function competition with a finite number of agents and private information. We show that any degree of market power can arise in the unique equilibrium under an information structure that is arbitrarily close to complete information. Regardless of the number of agents and the correlation of payoff shocks, market power may be arbitrarily close to zero (the competitive outcome) or arbitrarily large (so there is no trade). By contrast, price volatility is always lower than the variance of the aggregate shock across all information structures. Alternative trading mechanisms lead to very distinct bounds as a comparison with Cournot competition establishes.     

Policy Consequences of Multiple Equilibria and the Indeterminacy of Economic Outcomes in a Boundedly Rational World: Closing the System with Non-Economic Variables1

In the conventional economic wisdom, the notion of unique equilibria that are efficient and Pareto optimal dominates the modeling discourse. Hebert Simon proposed an alternative analytical framework where the notion of multiple and sustainable equilibria is critical. Multiple equilibrium is the crucial stylized fact of economic life that requires better understanding and modeling. Of particular significance, Simon touched on the importance of institutions and differential power relationships in affecting economic outcomes. But this modeling approach was not well developed by Simon. Following from his contributions, further develop the notion of multiple equilibria especially in the realm of production with an emphasis on x-efficiency theory. I bring to bear the importance of institutional parameters (including power relationships), culture, norms, ethics, and moral sentiments to the determination of economic outcomes. In the model developed here, boundedly rational decision-makers’ choices are contextualized and constrained by complex environmental factors. No one choice is either inevitable or economically efficient. A multiplicity of outcomes is possible and sustainable inclusive of those that are suboptimal. Much depends on individual preferences and institutional design. This has significant implication for institutional design and policy.     

A network approach to modeling the multi-echelon spare-part inventory system with backorders and interval-valued demand

A multi-echelon inventory system implies the existence of a hierarchy of stocking locations, and the dependence and interaction between them. We consider a multi-echelon, spare-part inventory management problem with outsourcing and backordering. The problem is characterized by deterministic repair time/cost, and supply and demand that lie within prescribed intervals and that vary over time. The objective is to minimize the total inventory and transportation costs. We develop a network model for problem analysis and present a network flow algorithm for solving the problem. We prove that the Wagner-Whitin property, known for the lot-sizing problem, can be extended to the spare-part inventory management problem under study.     

Accounting for Gender in a Study of the Motivation-Involvement Relationship

ABSTRACT

The effects of gender on involvement in high-risk recreation have received limited research attention despite mounting evidence suggesting the learned interactions between people and places likely vary for men and women. The purpose of this study was to provide insights into how gender influenced the motivation-involvement relationship among whitewater recreationists on a Wild and Scenic River in California. Our results revealed the motivations of Risk, Escape, Learning, and Achievement/Stimulation positively influenced involvement in rafting activities. Although gender did not influence all dimensions of involvement, we found that identity expression varied between subgroups. Specifically, men were more likely to ascribe meaning to rafting than women because this activity allowed them to affirm and express their individual character. The implications emanating from this study advance theoretical understanding of the factors that influence enduring involvement and inform natural resource management decisions about maintaining the desired benefits of activities sought by nature-based recreationists.     

Opening up the black box: a UK case study of top managers’ attitudes to their performance related pay

This paper examines the attitudes of the top managers within one large financial services organization in the UK to fixed and variable components of their compensation package. The rationale for performance-related pay for senior managers is to align their interests with those of the shareholders, but little is known about the views of top managers on the effectiveness of such incentives. The results suggest that the design of effective bonus systems is not just a technical issue: perceptions of market fairness with respect to the compensation package and the clear communication of goals are important in getting senior managers to focus on shareholder interests.     

The organization of the future: Unity of marketing and strategy

Marketing and strategy, while once diverse activities and entities, are moving ever closer together—in this paper it is speculated that they may someday become one. This is in response to changing business environments, and to the emergence of new organizational forms. However, a more fundamental force may be the simple recognition that without relationships there is no need for strategy, and that relationships are fundamental to marketing.     

Federal capital expenditures and budget deficits: Gross national product and labor implications

The issue of separating capital from operating expenditures has been largely ignored in discussions of the U.S. Federal Government's deficit. This paper attempts to overcome this void by conducting a simulation experiment designed to assess the macroeconomic consequences of separating capital from current expenditures under several alternative balanced budget rules and financing arrangements. The alternatives considered are directly related to management accounting issues and thus the purpose of this paper can be seen as compatible with the literature on the relationship between accounting techniques and economic analyses. The results of the study reaffirm the need for federal capital investment planning.     

The role of moral intensity in moral judgments: An empirical investigation

Jones (1991) has proposed an issue-contingent model of ethical decision making by individuals in organizations. The distinguishing feature of the issue was identified as its moral intensity, which determines the moral imperative in the situation. In this study, we adapted three scenarios from the literature in order to examine the issue-contingent model. Findings, based on a student sample, suggest that (1) the perceived and actual dimensions of moral intensity often differed; (2) perceived moral intensity variables, in the aggregate, significantly affected an individual's moral judgments; and (3) some dimensions of moral intensity (namely, perceived social consensus and perceived magnitude of consequences) mattered more than others.Sara A.
