Emotions and Digital Delivery Platforms
2021
From the global spread of the infectious disease COVID-19, in Argentina as in other states worldwide, health measures, social emergency, economic and public order measures were taken. One of the main and earliest measures of social order in the face of this disease was the delimitation of a period of population isolation, known as preventive and obligatory social isolation. The compulsory social isolation generated unprecedented growth in the demand for services to the platform economies in Argentina in general and in Buenos Aires in particular, causing the platform delivery activity to be conceived as an essential activity. The purpose of the writing is to explore the configuration of a ce…
Instituciones y determinación de los salarios en la zona del euro. Evaluación con técnicas de cointegración de panel
2016
Se estima aqui la ecuacion del salario de equilibrio para la zona del euro en 1995-2011 con tecnicas de cointegracion de panel que permiten dependencia transversal y rupturas estructurales. Como se esperaba, los salarios presentan una relacion positiva con la productividad y negativa con el desempleo. Las variables institucionales incluidas muestran correlacion entre flexibilidad y moderacion salarial. Ademas, desde 2004, la mayor competencia internacional reforzo la relacion entre salarios y productividad, y la apreciacion del tipo de cambio provoco una caida salarial. Los resultados indican tambien que la intervencion gubernamental y la concertacion social tienden a moderar los salarios.

Multivariate modeling and analysis of regional ocean freight rates
2018
Abstract In this paper, we propose a new multivariate model for the dynamics of regional ocean freight rates. We show that a cointegrated system of regional spot freight rates can be decomposed into a common non-stationary market factor and stationary regional deviations. The resulting integrated CAR process is new to the literature. By interpreting the common market factor as the global arithmetic average of the regional rates, both the market factor and the regional deviations are observable which simplifies the calibration of the model. Moreover, forward contracts on the market factor can be traded in the Forward Freight Agreement (FFA) market. We calibrate the model to historical spot r…
Information nutritionnelle, choix et caractéristiques des consommateurs
2012
Consumers’ food decisions are based on the information they receive and on their own individual characteristics. This paper is based on an experiment using experimental economics and sensory evaluation to measure individual characteristics of participants and to analyze the impact of nutritional information relative to orange juice. The aim is to explore the potential link between specific characteristics (risk aversion, time preference) and the reactions of consumers to nutritional information. The results show that participants react significantly to this information supplied, positively for the pure orange juice and a negatively for orange nectars. In addition, “risk averse” individuals …
The many faces of human sociality: uncovering the distribution and stability of social preferences
2018
There is vast heterogeneity in the human willingness to weigh others' interests in decision making. This heterogeneity concerns the motivational intricacies as well as the strength of other-regarding behaviors, and raises the question how one can parsimoniously model and characterize heterogeneity across several dimensions of social preferences while still being able to predict behavior over time and across situations. We tackle this task with an experiment and a structural model of preferences that allows us to simultaneously estimate outcome-based and reciprocity-based social preferences. We find that non-selfish preferences are the rule rather than the exception. Neither at the level of …
Robots, labor markets, and universal basic income
2020
Automation is a big concern in modern societies in view of its widespread impact on many socioeconomic issues including income, jobs, and productivity. While previous studies have concentrated on determining the effects on jobs and salaries, our aim is to understand how automation affects productivity, and how some policies, such as taxes on robots or universal basic income, moderate or aggravate those effects. To this end, we have designed an experiment where workers make productive effort decisions, and managers can choose between workers and robots to do these tasks. In our baseline treatment, we measure the effort made by workers who may be replaced by robots, and also elicit firm repla…
Does the GATT/WTO promote trade? After all, Rose was right
2019
This paper re-examines the effect of the GATT/WTO on trade using recent econometric developments that allow us estimating structural gravity equations with the Poisson pseudo-maximum likelihood (PPML) estimator on a large dataset that requires computing high-dimensional fixed effects. By doing so, we overcome computational limitations that are present in previous studies. In line with Rose’s (Am Econ Rev 94:98–114, 2004) seminal work, we find that, unlike regional trade agreements and currency unions, the GATT/WTO accession has not generated positive trade effects. This result is robust to the use of alternative measures of trade flows, across periods and country groups, to changes in the p…
Empirical Evidence on the Relationship between Mobile Termination Rates and Firms' Profits
2015
The theoretical literature on mobile termination rates (MTRs) is inconclusive on how the level of MTRs affects overall consumer charges and firms' profits. We show that when firms offer bundles with fixed included usage – a tariff structure that has become more common in recent years – an identical change in all MTRs does not affect firms' retail prices or profits. We use a panel dataset from saturated European markets to estimate the effect of MTRs on mobile operators' profits. As predicted by the theoretical model, we cannot reject the fact that firms' profits are unaffected by an identical change in all MTRs.
La valorisation des compétences de base sur le marché du travail français
2013
D’après la théorie du capital humain, les individus sont rémunérés selon leur productivité, productivité qui dépend elle-même du niveau de diplôme ou du nombre d’années d’études. Mais à l’heure où l’éducation certifiée est discutée comme filtre, qu’en est-il de la valorisation des compétences, notamment de base, sur le marché du travail français ? Alors que de nombreuses recherches ont déjà été réalisées à ce sujet (dans les pays anglo-saxons principalement), aucune n’a encore été conduite sur cette thématique en France. Cette présente étude cherche alors à déterminer, via un modèle d’Heckman en deux étapes, dans quelle mesure l’accès à l’emploi et les salaires sont expliqués par le niveau …
