Dynamics of Local Wages and Employment: Evidence from the Venezuelan Immigration in Colombia
The unprecedented socioeconomic and political deterioration of Venezuela has triggered a massive outflow of people leaving the country since 2016, both in a voluntary and a forced manner. Colombia has been the major receiver country with more than 1.2 million working-age Venezuelans (4.1% of the working-age population living in Colombia) as of 2019. I use this quasi-natural experiment to identify the causal impact of the Venezuelan immigration on the Colombian labor market. To analyze dynamic treatment effects I implement an event-study design with two different shift-share instruments. For both instruments I find that immigration from Venezuela had a highly negative short-run effect on local native wages since 2017, and the impact is mainly suffered by less skilled workers and workers without access to social security. Moreover, wages in lower percentiles of the native local wage distribution are severely more affected compared to those in upper percentiles. In terms of native employment, I find a delayed negative response after controlling for preexisting trends. On aggregate, the supply shock affected mainly the informal labor market with lower wages and higher employment on average.

Trade Facilitation and Participation in Global Value Chains
écrit avec Leila Baghdadi (University of Tunis, ESSECT, DEFI, World Trade Organization Chair at University of Tunis) and Inmaculada Martínez Zarzoso (University of Gottingen, University Jaume I)
This paper investigates the effect of trade facilitation on forward and backward Global Value Chains (GVCs) in manufacturing sectors. We use a two-step gravity model of trade for a cross-section of countries over the period 2004-2015. The main aim is to shed some light on whether the effect of maritime connectivity and border procedures on value-added content of trade differ by region. Results indicate that maritime connectivity matters for trade under GVCs. In particular, exporting intermediate goods is highly encouraged by more efficient maritime routes which connect different participants of GVCs in Africa and Asia. Furthermore, shipping goods without delays, low costs and simpler procedures are key determinants of participation in forward GVCs. Finally, the regional analysis for manufacturing sectors of GVCs helps to discern which regions are more affected by cross-border reforms and reveals that simplifying documentary procedures is important for Africa, Asia and Europe when they import foreign value-added. For instance, less time to import encourages Africa to participate in backward linkages in GVCs and transportation costs matter for Africa when it operates upstream tasks and for Europe when it operates upstream and downstream tasks.

Dynamic cheap talk with no feedback
We study a dynamic sender-receiver game, where the sequence of states follows a Markov chain. The sender provides valuable information but gets no feedback on the receiver’s actions. Under certain assumptions, we characterize the set of uniform equilibrium payoffs with the help of a static cheap talk game, where the marginal distribution of messages is fixed. We show that the sender is able to bridge the value of commitment and secure the Bayesian persuasion payoff of the static game.
