Martinoty, L. (2014) « Stratégie familiale de gestion des chocs : l’offre de travail des épouses en
réponse aux fermetures d’entreprise en Argentine », Revue Économique, 65, pp. 537-566.
Cet article a pour objectif d’étudier le rôle de la famille comme mécanisme d’assurance lorsqu’un
choc touche le revenu du travail du pourvoyeur principal du ménage. En incertitude, le modèle du
cycle de vie prédit qu’un tel choc a un impact positif sur l’offre de travail de son conjoint. Données
de panel à l’appui, nous testons l’existence de cet « effet travailleur additionnel » (ETA) lors de
la récession argentine. L’endogénéité inhérente aux variables inobservables et à la simultanéité
des décisions des deux époux est contrôlée en introduisant des effets fixes individuels, et en
utilisant les fermetures d’entreprise comme un choc exogène négatif de revenu. Le modèle est
estimé par différence de différence avec appariement. Le motif stratégique rend compte de 12,5%
de l’augmentation totale de la participation féminine. Une femme a 13 points de pourcentage de
chance supplémentaire d’entrer sur le marché du travail si son conjoint perd son emploi. A la
marge intensive, la participation reste inchangée.

Martinoty, L. (2015) « Intrahousehold Coping Mechanisms in Hard Times: the Added Worker
Effect in the 2001 Argentine Economic Crisis », GATE WP 2015-05. Imminent submission to World
Development, CNRS Rank 1.
This paper shows that the added-worker effect (AWE) plays an important role in coping against
aggregate shocks, even in cases where the discouragement effect prevails at a macroeconomic scale.
Using an Argentine panel dataset between 2000-2002, we instrument the endogenous variation
in the labor market outcomes of household heads using the collapse of the convertibility era as
a natural experiment, and measure its causal impact on their spouses’ labor supply decisions.
Within this framework, we show that a woman whose husband experiences the average decline in
income (resp. looses his job) is 4.4 percentage points more likely to enter the labor market (resp.
43 percentage points). Out of four new entrants, three work at least one hour weekly, and one
even finds a full time job. Heterogeneous effects are in line with expectations, robustness checks
support the validity of our empirical strategy, and our results are robust to various sensitivity
tests.

« Crisis at Home: Martinoty, L. and O. Bargain (2015) « Mancession-Induced Change in Intrahouse-
hold Distribution ». Imminent submission to the Journal of European Economic Association, CNRS
Rank 1.
The Great Recession has often been referred to as a ‘mancession’ in several countries including
Spain and the US. Although women did experience substantial job losses during the recession,
the crisis hit men harder than women for they were disproportionately represented in heavily
affected sectors such as construction, manufacturing and financial services. To date, nothing is
known about the way the mancession has translated within the household. More generally, we
know little about how labor market opportunities affect intrahousehold distribution. To study
this issue, we exploit the exogenous, gender-oriented evolution of the economic environment in
Spain. Using consumption data from 2006-2011, we adapt and estimate a collective model of
consumption which allows testing original distribution factors. In particular, we allow the sharing
rule to depend on regional-time variation in relative job opportunities during the mancession.
Looking more specifically at the gender-differentiated shock from the construction sector, we also
