Principal‐agent and Peer Relationships in Tournaments

Effort provision in tournaments may depend on both social preferences towards the competitor and social preferences towards the principal who designed the tournament. In a laboratory experiment, we analyze agents' behavior in different tournament settings that vary the distribution of the prize between agents. The principal chooses between a low and a high guaranteed payment. Standard economic theory predicts the same effort provision in all situations. Instead, our results show that both the generosity of the principal and the strict separation between winner and loser increase the effort level in tournaments. Moreover, agents focus their preferences either on the principal or on the agent. Copyright © 2014 John Wiley & Sons, Ltd.     

Hedging American Options in Merton's Model: A Locally Risk Minimizing Approach

An interesting problem, related to American options in incomplete markets, is the possibility to select a preferable equivalent martingale measure in order to compute the prices. With this in mind, we consider a particular option that may be viewed as a finite collection of suitable European options and for which the minimal martingale measure permits the minimization of the local risk. Since this option is an approximation of the American put, the stability result presented, concerning the portfolio decomposition, also suggests an argument in favor of the minimal martingale measure in the American case.     

Negative Affect and Counterproductive Workplace Behavior: The Moderating Role of Moral Disengagement and Gender

There has been growing scholarly interest in understanding individual-level antecedents of counterproductive workplace behavior (CWB). While researchers have found a positive relationship between individuals’ negative affect and engagement in CWB, to date, our understanding of the factors which may affect this relationship is limited. In this study, we investigate the moderating roles of moral disengagement and gender in this relationship. Consistent with our hypotheses, we found that individuals with a greater tendency to experience negative emotions were more likely to engage in CWB when they had a higher propensity to morally disengage. Moreover, we found that this interacting relationship varied across men and women. We discuss the theoretical and practical implications of our findings and offer avenues for future research.     

Socioeconomic Index for Income and Poverty Prediction: A Sufficient Dimension Reduction Approach

The present paper introduces a novel method for the construction of Socioeconomic Status (SES) indices that are specific to a target variable of interest. It is based on the Sufficient Dimension Reduction (SDR) paradigm and uses a factorized model-based approach to simultaneously deal with predictor variables of mixed nature (i.e. quantitative, binary, and ordinal), which are usual in microeconomic data. These SES indices also identify relevant predictor variables using a two-step regularized matrix factorization approach. Using data from household surveys for Argentina (Encuesta Permanente de Hogares-EPH), the proposed method is compared with other existing dimension reduction algorithms such as standard Principal Component Analysis (PCA) and its version for mixed variables, regression on the full set of variables and Least Absolute Shrinkage and Selection Operator regression (LASSO).     

Treat yourself: Food delivery apps and the interplay between justification for use and food well-being

This study examines the relationship between justification for use and well-being in respect to mobile food delivery apps (FDA). Adopting an interpretivist qualitative approach, the study offers contributions to the FDA and food well-being literature by uncovering four groups of licensing effects that consumers use in justifying FDA use. Those licensing effects can have either positive or negative influence on consumers' well-being depending on the degree to which consumers engage in self-regulation, awareness, and conscious managing of their relationship with food. The study also unravels the importance of dealing with the tensions between FDA use and well-being by shedding light on feelings of guilt and financial anxiety related to FDA use.     

Dispersion in Dispersion: Measuring Establishment-Level Differences in Productivity

We describe new experimental productivity dispersion statistics, Dispersion Statistics on Productivity (DiSP), jointly produced by the Bureau of Labor Statistics (BLS) and the Census Bureau, that complement the official BLS industry-level productivity statistics. The BLS has a long history of producing industry-level productivity statistics, which represent the average establishment-level productivity within industries when appropriately weighted. These statistics cannot, however, tell us about the variation in productivity levels across establishments within those industries. Dispersion in productivity across businesses can provide information about the nature of competition and frictions within sectors and the sources of rising wage inequality across businesses. DiSP data show enormous differences in productivity across establishments within industries in the manufacturing sector. We find substantial variation in dispersion across industries, increasing dispersion from 1997 to 2016, and countercyclical total factor productivity dispersion. We hope DiSP will enable further research into understanding productivity differences across industries and establishments and over time.
