Is limit pricing evolutionarily stable?

We have analyzed the question whether or not limit-pricing behavior can be viewed as a strategy, which survives the replicator dynamics in a game in which firms change strategies through imitation. Our results show that, regardless of the proportion of low cost incumbents in the population, potential entrants that play the strategy "enter" when they observe limit output are wiped out. The unique ESS consists of all low cost incumbents playing the "limit output" strategy, and all high cost incumbents playing the "monopoly output". This ESS includes potential entrants playing "stay out" after observing the limit output, and playing "enter" if monopoly output is observed in the first stage. Hence, limit pricing survives the replicator dynamics and appears in the stable state of the population.JEL Classification: B25, C73, L11We would like to thank an anonymous referee for valuable comments on an earlier version of this paper.

Choosing research priorities by using the analytic hierarchy process: an application to international agriculture

In order to strengthen research coordination and increase the effectiveness of investments, the Swiss Centre for International Agriculture (ZIL) embarked on a formal priority-setting exercise. The paper documents the decision-making process, examines the application of the analytic hierarchy process (AHP) as decision-support tool, and discusses the outcome of the process. Starting with a set of alternative research areas and potential decision criteria, the process went through several steps where necessary information was gathered and processed, criteria structured and weighted, and alternative research areas assessed against criteria. The AHP helped structure the multi-criteria decision problem, elicit criteria weights, and evaluate the expected contributions of the alternatives to the previously defined objectives. The outcome of the process was a prioritized list of potential research areas for ZIL's next programme phase. Sensitivity analysis was performed to test the stability of the priority ranking. The paper concludes with a discussion on the group decision-making process and an outlook onto the next steps towards a better focused research agenda of ZIL.     

Satisficing behavior, Brouwer’s Fixed Point Theorem and Nash Equilibrium

Summary. We show that Nash Equilibrium points can be obtained by using response maps or reply functions that simply use better responses rather than best responses. We demonstrate the existence of a Nash Equilibrium as the fixed point of a better response map and since the better response map is continuous the fixed point can be established by simply using Brouwers fixed point theorem. The proof applies to games with a finite number of strategies as well as to games with a continuum of strategies. In case the games have a continuum of strategies the payoff functions have to be continuous on the action sets and quasi concave on the players action set.Received: 22 September 2003, Revised: 31 March 2004, JEL Classification Numbers: C72, D00, D40.

Housing Price Forecastability: A Factor Analysis

We examine U.S. housing price forecastability using principal component analysis (PCA), partial least squares (PLS) and sparse PLS (SPLS). We incorporate information from a large panel of 128 economic time series and show that macroeconomic fundamentals have strong predictive power for future movements in housing prices. We find that (S)PLS models systematically dominate PCA models. (S)PLS models also generate significant out‐of‐sample predictive power over and above the predictive power contained by the price–rent ratio, autoregressive benchmarks and regression models based on small datasets.     

Cross-Industrial User Channel Preferences on the Path to Online Purchase: Homogeneous,Heterogeneous, or Mixed?

Though research literature addresses a broad range of advertising impact models, studies on the channel preferences of online purchasers have received little attention, regarding both multichannel settings and channel interplay in click sequences. To provide advertisers a method for better evaluating customer channel preference, this study investigates the path to purchase by building on four multichannel clickstream data sets from three industries, recorded with cookie-tracking technologies. Applying a Cox model and clustering techniques supports delineation of empirical generalizations and industry-specific findings on channel exposure, including their antecedents and distinct channel click sequences. Across data sets, online users show idiosyncratic channel preferences for a limited set of one or two channels rather than multiple online vehicles. Both channel homogeneous click sequences and combinations of two channels (including branded contacts) are effective as purchase predictors. Our study also presents industry-specific results regarding the influence of click sequences on purchase intent, thereby providing insights for advertising research, particularly as are suited to optimization of online advertising activities.     

Ideology and the Balanced Scorecard: An Empirical Exploration of the Tension Between Shareholder Value Maximization and Corporate Social Responsibility

In a society where the ideology of shareholder value maximization (SVM) prevails, how do evaluators make appraisal and bonus decisions when corporate social responsibility (CSR) measures and financial measures in the balanced scorecard (BSC) point in different directions? To explore this question, we conducted two studies to develop and test a conceptual framework. Participants were asked to evaluate the performance of two managers, using a case we wrote about a commercial bank. We found that (1) evaluators are more willing to drop CSR performance measures than financial measures from the evaluations; (2) perceived CSR relevance is influenced by where evaluators stand in regard to CSR (“stakeholder view” in the “Perceptions of the Role of Ethics and Social Responsibility” or PRESOR scale) and also by where evaluators believe shareholders stand (shareholder support); and (3) there is a financial bias in appraisal and bonus decisions when CSR measures are used in the BSC, consistent with SVM ideology. We conclude by discussing the implications of the influence of SVM ideology on the use of CSR measures in terms of business research, practice, and education.     

Does implied volatility provide any information beyond that captured in model-based volatility forecasts?

This paper contributes to our understanding of the informational content of implied volatility. Here we examine whether the S&P 500 implied volatility index (VIX) contains any information relevant to future volatility beyond that available from model based volatility forecasts. It is argued that this approach differs from the traditional forecast encompassing approach used in earlier studies. The findings indicate that the VIX index does not contain any such additional information relevant for forecasting volatility.
