Mardi | 2016-06-07 10h00-11h20 Inmaculada MARTíNEZ-ZARZOSO – Florian JOHANNSEN This paper investigates the determinants of indirect exporting using firm-level data for 27 countries in Eastern Europe and Central Asia. Indirect exporting depends on a combination of fixed and variable trade cost factors. We hypothesize that firms that perceive transportation, crime, legal systems and corruption as severe obstacles face higher fixed costs and are more likely to export indirectly and that indirect exporting tends to be a temporary strategy. Econometric models […]

We rely on a life cycle model (Hugonnier et al., 2013) with health spending, portfolio, insurance and consumption decisions for which we […]

Mardi | 2016-05-31 16h20-17h40 en Sully05 Yang CHAO – Lung-fei LEE – Xi QU We build a model to analyze censored behaviors for socially associated agents under ageneral form of incomplete information. Employing the analytical tools used by Yang andLee(2014), we find that there is a unique equilibrium when parameters are within a reasonablerange. We utilize the rate of censoring and the average observed outcomes to identifymodel parameters. We suggest estimating the model by the maximum likelihood methodwith inner-loop fixed […]

Mardi | 2016-05-24 16-17h20 salle des thèses Xavier RAURICH – Edgar CRUZ In the second half of the twenty century we observe two important patterns of structural change; first, a large shift of employment from the agriculture and manufacturing sectors to the service sector, and, second, a sustained increase in the amount of time devoted to leisure activities. We relate these two patterns of structural change by arguing that during leisure time we consume recreational services. The observed increase in […]

Mardi | 2016-05-17 16-17h20 Sully05 Christian DE PERETTI – Hanene BEN SALAH – Mohamed CHAOUCH – Ali GANNOUN – Abdelwahed TRABELSI The DownSide Risk (DSR) model for portfolio optimisation allows to overcome the drawbacks of the classical Mean-Variance model concerning the asymmetry of returns and the risk perception of investors. This model optimization deals with a positive definite matrix that is endogenous with respect to portfolio weights. This aspect makes the problem far more difficult to handle. For this purpose, […]

Mardi | 2016-05-10 16h-17h20 Sully05 Sandrine NOBLET The aim of this paper is to link the complexity of production process and the geographical dimension of fragmentation. More specially, we address the following questions: 1) how does complexity affect import volumes? and 2) how does complexity act the sensitivity of trade flows to the distance? To do so, we construct an indicator of complexity from US input-output tables. This indicator is then introduced in a gravity equation (using Comtrade Data) as […]

Mardi | 2016-04-19 Sully05 de 16h à 17h20 Pierre-Guillaume MEON Using two surveys, we study how respondents process visual cues to identify the political orientation (left- vs. right-wing) of French deputies, based on their official photographs only, to test the type of heuristic that they use. We first confirm that respondents outperform random guesses. Second, we find that their categorizations correlate with observable characteristics (gender, color of the tie, jewelry) and subjective assessments of deputies’ personality traits (attractiveness, competence, trustworthiness).
