One little Lebanese cucumber is not going to break the bank: Price in the choice of fresh fruits and vegetables

This paper reports on empirical research into individual consumer behaviour in the context of fresh fruit and vegetable purchases. The discussion draws on research results from two studies conducted around the actual shopping process. The findings suggest that consumers' price response behaviour may not be consistent with that predicted by economic theory and that this could be significant at the aggregate level. The existence of 'acceptable price ranges' points to the presence of price thresholds within which consumers are relatively insensitive to price movements. Also of relevance is that the primary influence of the budget constraint may be at a broader level rather than at the level of choosing particular products.     

More on money as a medium of exchange

Summary We extend the analysis of Kiyotaki and Wright, who study economies where the commodities that serve as media of exchange (or, commodity money) are determined endogenously. Kiyotaki and Wright consider only steady-state, pure-strategy equilibria; here we allow dynamic and mixed-strategy equilibria. We demonstrate that symmetric, steady-state equilibria in mixed-strategies always exist, while sometimes no such equilibria exist in pure-strategies. We prove that the number of symmetric steady-state equilibria is generically finite. We also show, however, that for some parameter values there exists a continuum of dynamic equilibria. Further, some equilibria display cycles.We thank the National Science Foundation and the University of Pennsylvania Research Foundation for financial support, as well as seminar participants at Stanford University, the London School of Economics, the Econometric Society World Congress in Barcelona, and the Conference on Monetary Theory and Financial Institutions at the Federal Reserve Bank of Minneapolis for their comments or suggestions.

Indivisibilities,lotteries, and sunspot equilibria

Summary We analyze economies with indivisible commodities. There are two reasons for doing so. First, we extend and provide some new insights into sunspot equilibrium theory. Finite competitive economies with perfect markets and convex consumption sets do not allow sunspot equilibria; these same economies with nonconvex consumption sets do, and they have several properties that can never arise in convex environments. Second, we provide a reinterpretation of the employment lotteries used in contract theory and in macroeconomic models with indivisible labor. We show how socially optimal employment lotteries can be decentralized as competitive equilibria without lotteries once sunspots are introduced.We thank Kenneth Arrow, Aditya Goenka, Ed Green, Jeremy Greenwood, Walter Heller, Steve Matthews, Herve Moulin, Roger Meyerson, Jim Peck, Patrick Kehoe, Ramon Marimon, Ed Prescott, Richard Rogerson, Nancy Stokey and Raghu Sundaram for their comments.

Tax Clientele Effects in the Term Structure of UK Interest Rates

This paper tests for tax clientele effects in the term structure of UK interest rates. Five empirical models of the term structure of interest rates, incorporating tax effects, are estimated with daily data covering the period 31 March, 1995 to 3 August, 1995. In May 1995, the British government announced its intention to eliminate the tax exemption on capital gains from government bonds, but subsequently in July 1995 backtracked on some of its initial proposals. This period therefore forms the basis of a crude natural experiment in the sense that it provides an opportunity to examine tax clientele effects 'before' and 'after' an event which should have levelled greatly the taxing of government bonds. The empirical analysis suggests large tax clientele effects. However, there is little evidence of tax-specific term structures of interest rates.     

A pilot study of venture capital investment appraisal in Australia

Illiquidity, volatile returns and lack of information are sources of the high risk that characterise the investments made by venture capitalists (VCs). Despite the importance of such investments in the contemporary business and technological environment, and the associated risk-related difficulties, little Australian research has been conducted into the decision-making processes of VCs. This study investigates both the investment process and some of the strategies used by VCs for reducing selected risks. The specific source of risk examined is information asymmetry, which is caused by lack of information on the part of the VCs, and which can lead to the added risks of adverse selection and moral hazard. Four Australian VC firms were surveyed using a comprehensive open-ended questionnaire. A manual content analysis was employed to analyse the questionnaire responses. Consistent with prior research, the Australian VCs sampled are found to employ Berger and Udell' three steps of investment: selection, contracting and monitoring. Furthermore, the semi-formal selection step of the investment process is found to consist of three distinct stages: deal sourcing, screening and evaluation. A number of techniques are used to minimise the risks of information asymmetry during the screening and evaluation stages, as well as during the later steps of contracting and monitorin.     

Company employment policies and new technology

Here the author presents case studies from a range of industries which illustrate the connection between new technology, and company personnel and manpower policies. Findings suggest that the form and direction of new technology is more likely to be affected by the company's employment policy rather than the reverse.     

Decisions,Actions, and Performance: Do Novice,Serial, and Portfolio Entrepreneurs Differ?*

A conceptual framework is extended to take into account differences between inexperienced novice entrepreneurs (that is, individuals with no prior private business ownership experience) and experienced serial and portfolio entrepreneurs. Some policymakers and practitioners are considering whether resources could be more effectively utilized if they were targeted toward serial and portfolio entrepreneurs, rather than in the form of additional initiatives to increase the pool of “pure” nascent entrepreneurs and novice entrepreneurs. To inform this policy debate, similarities and differences between novice, serial, and portfolio entrepreneurs are highlighted with regard to their decisions, actions, performance, and aspirations. We detected that portfolio entrepreneurs were more likely to express dimensions of entrepreneurial behavior. A case for targeted support tailored to the aspirations and needs of novice, serial, and portfolio entrepreneurs is presented.     

The false promise of technological determinism: the case of enterprise resource planning systems

According to software vendors and consultants, Enterprise Resource Planning systems (ERPs) transform the nature, structure and management of work regardless of organisational context. This paper contests this technologically deterministic view of organisational change by demonstrating the role that discourse plays in the social construction of ERPs.
