Measuring the cost of capital when taxes are changing with foresight

The familiar Hall-Jorgenson (1967) cost of capital perturbation is not a uniquely feasible one. Because of institutional features of actual tax systems, the optimal holding time for an incremental unit of capital will generally be infinite. The impossibility of an optimal rule for recapturing excess depreciation allowances on disposal is demonstrated. When tax changes are foreseen, the ‘error’ in the traditional measure of cost of capital can become highly significant. Ignorance of this effect led to underestimates of the extent to which the radical changes to the U.K. Corporation Tax in 1984 would affect cost of capital and incentives to forestall planned investment.     

A short proof of Harsanyi''s purification theorem

A short proof of more general version of Harsanyi's purification theorem is provided through an application of a powerful, yet intuitive, result from algebraic topology.     

Costly enforcement of property rights and the Coase theorem

We examine a setting in which property rights are initially ambiguously defined. Whether the parties go to court to remove the ambiguity or bargain and settle before or after trial, they incur enforcement costs. When the parties bargain, a version of the Coase theorem holds. However, despite the additional costs of going to court, other ex-post inefficiencies, and the absence of incomplete information, going to court may ex-ante Pareto dominate settling out of court. This is especially true in dynamic settings, where obtaining a court decision today saves on future enforcement costs. When the parties do not negotiate and go to court, a simple rule for the initial ambiguous assignment of property rights maximizes net surplus. A paper circulated under the same title and dated 6 March 2000 contained the basic structure examined in this paper, but did not develop many of the results reported here. For comments, we would like to thank participants at the WZB-CEPR contests conference and seminar audiences at the University of Southern California, the University of British Columbia, UC Davis, and UC Riverside.     

Reinterpreting mixed strategy equilibria: a unification of the classical and Bayesian views

We provide a new interpretation of mixed strategy equilibria that incorporates both von Neumann and Morgenstern's classical concealment role of mixing, as well as the more recent Bayesian view originating with Harsanyi. For any two-person game, G, we consider an incomplete information game, in which each player's type is the probability he assigns to the event that his mixed strategy in G is “found out” by his opponent. We show that, generically, any regular equilibrium of G can be approximated by an equilibrium of in which almost every type of each player is strictly optimizing. This leads us to interpret i's equilibrium mixed strategy in G as a combination of deliberate randomization by i together with uncertainty on j's part about which randomization i will employ. We also show that such randomization is not unusual: for example, i's randomization is nondegenerate whenever the support of an equilibrium contains cyclic best replies.     

Customer and Competitor Insights,New Product Development Competence,and New Product Creativity: Differential,Integrative, and Substitution Effects

Developing creative new products requires a synthesis among customer‐oriented and competitor‐oriented learning, and new product development competence. However, underlying this synthesis is a paradox: how to integrate both customer and competitor insights within a technology‐centric new product development process. In order to examine the nature of this organizational tension, this study develops a conceptual framework and tests a series of six hypotheses with data generated from our study of creative new products within 187 high‐technology ventures in China. Differential effects are found in the way in which customer‐oriented learning (neutral) and competitor‐oriented learning (positive) relate to new product creativity. Their integration, meanwhile, is positively related to this new product outcome. Results also reveal that new product development competence, both independently and when integrated with customer‐oriented learning, positively impacts new product creativity. However, the study also reveals a surprising finding of a substitution effect where the combination of competitor‐oriented learning with new product development competence is inversely related to new product creativity. These findings are discussed, and their implications are derived for further research and both market and technology management.     

The cost of childhood injury in France

Injuries are a major public health problem worldwide. In the USA, injuries cause 146, 400 deaths annually, with 31 million non-fatal injury visits to emergency departments (EDs). EDs thus represent an important source of injury data. The primary objective of the current study was to describe the epidemiology of injury-related ED visits and assess injury-related utilization of health care resources in an inner-city hospital in Indiana, using data stored in a computerized medical record system. It involved a retrospective review of the records for injury visits to EDs and injury admissions over a 3-year period. The variables extracted and analysed included patients' demographics, external cause of injury, diagnosis, length of stay, ED and hospital charges. A total of 60,470 injury-related ED visits were made, the majority of patients were male (61.6%), uninsured (63.1%), treated in ED and discharged (98.4%). The leading causes of injury were falls (18.8%), motor vehicle crashes (18.4%), assaults (17.6%), being struck (11.2%) and overexertion (10.6). Firearms caused most injury deaths (32.4%; n = 314); motor vehicle crashes were the leading cause of hospitalization (26.6%; n = 642) and also the most expensive to treat as inpatients (mean charge $19,190). The mean charge per patient treated and discharged was $150 compared to $11,116 for patients admitted. These findings demonstrate the value of computerized medical records in capturing and storing E-coded injury data. The system generates data that can be used for epidemiological surveillance and injury prevention at the local level, and for assessment of impact of specific injuries on health care resources.     

The Influence of Regionalization and Cultural Distance on the Direction of Exports

Research has identified two distinct influences on the direction of firm internationalisation, cultural distance, and regionalisation. This paper sets out to test the strength of these influences on the direction of exports in circumstances where they act in different directions. The paper applies a quantitative methodology to a large, purposively compiled data set of Australian export values over the period 1990 to 2004. The Australian context provides an interesting case because its cultural linkages and its geographic connections lie in different directions. It is shown that regionalisation is the dominant influence on the direction of exports in the Australian context.     

The search for legitimacy and organizational change: The agency of subordinated actors

This article investigates the organizational changes triggered by the implementation of certified management systems (CMS) in Denmark and explores how institutionalized organizational practices change over time. The study shows that improvements in performance were not significant in the implementation of CMS, though in most cases its adoption implied organizational changes. The study also shows that the search for external legitimacy was appropriated by various internal organizational actors, other than management. When internal actors share the institutionalized beliefs and norms of the wider society, they implicitly strive to reduce decoupling. We argue that understanding the social dynamics of legitimacy in organisations requires paying attention to the agency of superordinated as well as subordinate actors.
