Fuzzy Differences-in-Differences

Mardi | 2017-05-16 16h00-17h20 salle des thèses Xavier D’HAULTFOEUILLE – Clément DE CHAISEMARTIN Difference-in-differences (DID) is a method to evaluate the effect of a treatment. In its basic version, a  » control group » is untreated at two dates, whereas a  » treatment group » becomes fully treated at the second date. However, in many applications of the DID method, the treatment rate only increases more in the treatment group. In such fuzzy designs, a popular estimator of treatment effects is the […]

GOLD AND MONEY IN RICARDO’S PRINCIPLES

Mardi | 2017-05-09 16h00-17h20 salle des thèses Ghislain DELEPLACE The integration of money in Ricardo’s theory of value and distribution is realised in Principles and the 1819-1823 papers by putting the standard of money centre stage. This raises two questions: Is money a commodity ? Is the standard of money (gold bullion) a commodity? The paper offers a negative answer to the first and a qualified positive one to the second. In Ricardo’s mature theory of money, in which the […]

Intermittent Discounting

Mardi | 2017-05-02 Salle des thèses de 16h00 à 17h20 A multi-period setting is studied in which a consumer incurs intermittent waiting costs until the consumption date. The way future utility is discounted satisfies (i) a preference for early consumption, but only during waiting periods when future consumption is reminded, and (ii) indifference between early and late consumption in non-reminding periods in which people are distracted away from future gratifications. With some additional hypotheses including exponential discounting of waiting costs, […]

Managing the Impact of Climate Change on Migration: Evidence from Mexico

Mardi | 2017-04-25 16h00-17h20 salle des thèses Isabelle CHORT – Maëlys DE LA RUPELLE This paper uses state-level migration flow data between Mexico and the U.S. from 1999 to 2011 to investigate the migration response to climate shocks and the mitigating impact of an agricultural cash-transfer program (PROCAMPO) and a disaster fund (Fonden). Our results suggest that droughts increase undocumented migration. Fonden amounts are found to mitigate the effect of climate shocks by lowering the undocumented migration response to precipitation […]

Competition and credit procyclicality in European banking

Mardi | 2017-04-11 16h00-17h20 salle des thèses Yannick LUCOTTE – Aurélien LEROY This paper empirically assesses the effects of competition in the financial sector on credit procyclicality by estimating both an interacted panel VAR (IPVAR) model using macroeconomic data and a single-equation model with bank-level European banking data. The findings of these two empirical approaches highlight that an exogenous deviation of actual GDP from potential GDP leads to greater credit fluctuation in economies where (i) competition among banks and (ii) […]

Cheap Talk ? Financial Sanctions and Non-Financial Activity

Mardi | 2017-04-04 Salle des thèses de 16h00 à 17h20 VOLKER NITSCH – TIBOR BESEDEš – STEFAN GOLDBACH Sanctions restrict cross-border interactions and, therefore, not only put political and economic pressure on the target country, but they also adversely affect the sender country. This paper examines the effect of financial sanctions on the country imposing them. In particular, we analyze the business responses of German non-financial entities to the imposition of sanctions, using highly disaggregated, monthly data from the German […]

Does the introduction of non-contributory social benefits discourage registered labour? Testing the impact of pension moratoriums on unregistered employment in Argentina (2003-2015)

Mercredi | 2017-03-29 B103 12h30 Leonardo Eric CALCAGNO In recent years, Argentina has reached nearly universal retirement benefits coverage. This was achieved through two successive pension moratoriums, implemented in the third quarter of 2006 and the third quarter of 2014, which allowed buying back missing contribution years and retire even with incomplete careers. In principle, the effect of moratoriums on unregistered employment is unclear: they may discourage retirement contributions by opening an alternative way for retiring, but they also may […]

Dynamics of Variance Risk Premia, Investors’ Sentiment and Return Predictability

Mardi | 2017-03-28 16h00-17h20 salle des thèses Joroen RAMBOUTS – Lars STENTOFT – FRANCESCO VIOLANTE We develop a joint framework linking the physical variance and its risk neutral expectation implying variance risk premia that are persistent, appropriately reacting to changes in level and variability of the variance and naturally satisfying the sign constraint. Using option market data and realized variances, our model allows to infer the occurrence and size of extreme variance events, and construct indicators signalling agents sentiment towards […]

Time for waste, waste of time ? Assessing heterogeneous values of saving time from recycling using a latent-class rank-ordered logit approach

Mardi | 2017-03-21 16h00-17h20 salle des thèses Olivier BEAUMAIS – Dominique PRUNETTI Although the opportunity cost of time spent recycling has long been recognized as a key determinant of household recycling participation, very few empirical studies have attempted to provide estimates of it. In this paper, we propose a model of household recycling that, while including pecuniary and non pecuniary motives for decisions, such as social and moral norms or warm-glow, reveals heterogeneous values of saving time from recycling (VSTR). […]

Regularized Generalized Empirical Likelihood Estimators

Mardi | 2017-03-14 16h00-17h20 salle des thèses Rachidi KOTCHONI – Marine CARRASCO Generalized Empirical Likelihood (GEL) estimators are solved by converting a high dimensional primal optimization problem into a dual Minimum Discrepancy problem with fewer parameters. When the GEL problem is subject to a continuum of restrictions, the duality relationships break down as the system of constraints becomes ill-posed. Duality is restored by solving a relaxed problem that leads to a family of Regularized GEL (RGEL) estimators. We show that […]
