Can Habit Formation be Reconciled with Business Cycle Facts

Abstract: Many asset pricing puzzles can be explained when habit formation is added to standard preferences. We show that utility functions with a habit then gives rise to a puzzle of consumption volatility in place of the asset pricing puzzles when agents can choose consumption and labor optimally in response to more fundamental shocks. We show that the consumption reaction to technology shocks are too small by an order of magnitude when a utility includes a habit. Alternative models with consistent and exogenous but stochastic labor input are considered. A model with persistent technology shocks and stochastic labor is shown to be potentially consistent with substantial consumption variability aswell as procyclical labor input and labor productivity even when a habit is present.

Understanding hybridity in public organizations

Abstract: This article explores and extends the concept of hybridity to understand current changes in public services organizations, notably as seen from an organizational studies perspective. The notion of hybridity has become more important, given that the public sector increasingly blurs with other sectors and more social actors. Previous reliance on the use of ideal-types in characterizing public services reforms has masked expanding heterogeneity. We here move beyond the (i) conventional focus on structural hybridity to consider (ii) institutional dynamics, (iii) social interactions, and (iv) new identities and roles in public services. Based on these four dimensions of hybridity, we review alternative theoretical frameworks. We suggest that bringing together work from the neighbouring disciplines of public administration and organization studies may improve our understanding of public services hybridity and outline a future research agenda.

What's in a p? Reassessing best practices for conducting and reporting hypothesis-testing research

Abstract: Social science research has recently been subject to considerable criticism regarding the validity and power of empirical tests published in leading journals, and business scholarship is no exception Transparency and replicability of empirical findings are essential to build a cumulative body of scholarly knowledge Yet current practices are under increased scrutiny to achieve these objectives JIBS is therefore discussing and revising its editorial practices to enhance the validity of empirical research In this editorial, we reflect on best practices with respect to conducting, reporting, and discussing the results of quantitative hypothesis-testing research, and we develop guidelines for authors to enhance the rigor of their empirical work This will not only help readers to assess empirical evidence comprehensively, but also enable subsequent research to build a cumulative body of empirical knowledge

Operations Research Games: a Survey

Abstract: This paper surveys the research area of cooperative games associated with several types of operations research problems in which various decision makers (players) are involved. Cooperating players not only face a joint optimisation problem in trying, e.g., to minimise total joint costs, but also face an additional allocation problem in how to distribute these joint costs back to the individual players. This interplay between optimisation and allocation is the main subject of the area of operations research games. It is surveyed on the basis of a distinction between the nature of the underlying optimisation problem: connection, routing, scheduling, production and inventory.
