Kalai and Muller’s possibility theorem: a simplified integer programming version

We provide a respecification of an integer programming characterization of Arrovian social welfare functions introduced by Sethuraman et al. (Math Oper Res 28:309–326, 2003). By exploiting this respecification, we give a new and simpler proof of Theorem 2 in Kalai and Muller (J Econ Theory 16:457–469, 1977).     

Practicing Human Dignity: Ethical Lessons from Commedia dell’Arte and Theater

The paper considers two main cases of how the creative arts can inform a greater appreciation of human dignity. The first case explores a form of theater, Commedia dell’Arte that has deep roots in Italian culture. The second recounts a set of theater exercises done with very minimal direction or self-direction in executive education and MBA courses at the Darden School, University of Virginia, in the United States. In both cases we highlight how the creative arts can be important for promoting human dignity in organizations, and how they can lead to a more authentic conversation about values, ethics, and meaning.     

Wages and Teachers’ Hours of Work

This paper seeks to estimate the effect of teachers net marginal wages on their working hours, on the basis of a survey of Dutch teachers. The resulting uncompensated wage elasticity is significantly positive and has an average value of 0.2 for males and 0.4 for females. However, a general wage increase is a rather costly solution to teacher shortages. Alternatively, working full-time can be made attractive for part-time teachers by providing a premium for full-time teachers. This kind of premium provides part-time teachers with a stronger incentive to work full-time, as the negative income effect does not occur. Simulation results show that such a premium produces an effect that is almost seven times as large as a general wage increase.     

Market-Channel Choices of Indonesian Potato Farmers: A Best–Worst Scaling Experiment

We present an empirical analysis of how buyer (and trader) attributes influence decisions of market participation and channel choice among smallholder potato farmers in West Java, Indonesia. We use a best–worst scaling experiment to evaluate the determinants of these decisions and gauge the influence of buyer attributes. Our latent-class cluster analysis reveals that producers have heterogeneous preferences for buyer attributes, which address classic smallholder constraints such as access to inputs, credit, and information. This heterogeneity can be somewhat explained by household characteristics and assets. The broad mass of our sample sought buyers whose attributes imply lower market risk for farmers. Yet roughly a quarter of our sample, a portion that included farmers with large, specialised farms, sought buyers who could provide inputs such as high-quality seeds.
