Divergence in Part-Time Work in New Zealand, the Netherlands and Denmark

A comparison of developments in part‐time work in New Zealand, the Netherlands and Denmark shows three very different trends. The Dutch are moving towards a ‘part‐time economy’, the decline in Danish part‐time employment confounds the common expectation of rising atypical employment, while the New Zealand case illustrates some of the negative employment outcomes often associated with part‐time employment and provides a contrast to the negotiated, tripartite solutions found in the Netherlands and Denmark. Overall, the diversity in part‐time work patterns raises important theoretical and public policy questions, such as the interaction between institutional and preference changes, gender patterns and union strategies.     

Exchange rate theories

Summary A four-period classification is used to categorise recent exchange-rate theories or models. In the very short period, only capital flows are relevant. In the short period, both capital flows and payments on the current account play a role. In the long period, the capital account and the current account are individually in equilibrium. In the very long period, purchasing power parity holds. Cash-in-advance models are dealt with separately. Many models that purport to explain exchange rates do in fact not provide for the exchange of currencies. No model stands up satisfactorily to econometric testing. Speculative bubbles, the peso problem and news play havoc with tests of the uncovered interest parity theorem, the core of the monetary models. This aside, the fundamental assumption of rational expectations itself is suspect. There does not seem to be such a thing as a true model.I am indebted to Dr. W.J.B. Smits and Professor J.W. Gunning for helpful discussions on a number of issues pertinent to this article.     

The Impact of Team Cognitive Styles on Performance of Radical and Incremental NPD Projects

Although prior studies increased our understanding of the performance implications of new product development (NPD) team members' functional backgrounds and demographic variables, they remained relatively silent on the impact of underlying psychological characteristics such as the team members' cognitive styles on project performance. The goal of this study is to explore the effects of NPD teams' cognitive styles on project performance in different kinds of NPD projects. Based on survey data from members of 95 NPD teams gathered in four Dutch manufacturing companies, hypotheses about the relationships between teams' cognitive styles and project performance of radical and incremental NPD projects are tested. Results of linear regression analyses show that the level of teams' analytical information processing positively affects project performance in both incremental and radical NPD projects, whereas the relationship between the level of teams' intuitive information processing and project performance depends on the radicalness of the project. These findings contribute to the academic discussion on team innovation, suggesting that, next to demographic and functional characteristics, cognitive styles in teams also significantly influence project performance.     

The Buyer's Option in Multi-Unit Ascending Auctions: The Case of Wine Auctions at Drouot

This paper studies multi-unit ascending (English) auctions with a buyer's option. The buyer's option gives the winner of an auction the right to purchase any number of units at the winning price. We develop a theoretical model and derive the optimal strategies for the bidders. The model predicts various behavioral implications (e.g., the winner never exercises the option, the price declines…) that are tested using a unique data set on wine auctions held at the Paris-based auction house Drouot. We also analyze why the buyer's option is used. Estimating the model in a structural econometric way, and using counterfactual comparisons, we find that the buyer's option does not affect the seller's revenue (relative to a system where the units are auctioned sequentially without the option). Drouot, however, saves a lot of time with the option and this effect represents a considerable amount of money. The time-saving effect seems thus to be the primary purpose of the buyer's option.     

Configurations of human resource practices and battlefield performance: A comparison of two armies

A prominent theme in the HRM literature is the organizational impact of configurations or “bundles” of human resource practices, mostly researched in business firms. A recurrent empirical finding here is that configurations of high performance HR practices generally have a more positive effect on employee attitudes and behavior and on organizational performance than configurations of traditional HR practices. In this paper this research is extended beyond business firms to include army organizations. Specifically it is argued, first, that these two configurations are exemplified in respectively the German Army and the US Army in World War II and second, that these configurations can be reasonably related to a relatively more effective battlefield performance of the German versus the US Army, even in spite of final defeat.     

A Study of Consumer Behavior Using Laboratory Data

This paper reports the results of an experiment in which subjects had to buy real products in 5 different budget/price situations. Subjects were randomly drawn from the population of a medium-sized French city, and some of their socio-economic characteristics were recorded. We check the consistency of product choices with the Generalized Axiom of Revealed Preferences (GARP), and find that 29% of the subjects are GARP-inconsistent. This inconsistency rate is slightly lower than the ones found in comparable studies. A possible explanation for our lower rate of GARP violations might be that the subjects in our study were confronted with less budget/price situations. In looking for determinants of the GARP violations, we find that gender, the size of the household, the degree of switching between different products, and the times spent on performing experimental tasks have significant impacts on the probability of GARP-inconsistency.     

Estimation of a hedonic price equation for Burgundy wine

A hedonic price equation and two jury grade equations are estimated for Burgundy wine. The approach is the same as in an earlier Bordeaux wine paper (Combris et al., 1997). The data come from an experimental study that is very similar to the study on Bordeaux wines. The results for the two wine-growing regions are compared and discussed.     

Constraints facing tourism entrepreneurs in South Africa: a study in the Gauteng and Mpumalanga provinces,South Africa

The current study is an investigation into tourism entrepreneurship of small, medium and micro enterprises in Gauteng and Mpumalanga. Through Principal Factor Analysis, the paper identifies a three-factor instrument that could be used as a diagnostic tool to investigate how government policies and support, the tourism industry's products and services, and perceptions about South Africa could advance or constrain the development of small, medium and micro tourism in South Africa. Such a tool can be used to identify problematic areas in order to take remedial action to manage sustainable tourism in South Africa and prevent the leakage of profits.
