Price adjustments on the market for human smuggling: Evidence from large demand shocks

with Lucas Guichard and Ismael IssifouPreliminary draft available upon request
Abstract
During the recent increase in the number of asylum seekers arriving in Europe, smugglers played a major in facilitating migration for persons without valid travel documentation. Yet, little is known about the smuggling market mechanisms. We analyse price changes of smuggling services following the large demand shock arising from the 2015 surge in persons seeking asylum in Europe. We exploit original survey data on asylum seekers in Germany combined with border crossings along the main routes towards Europe. Endogeneity concerns are addressed with an instrumental variable approach based on casualties due to terrorist attacks in the country of origin. We find that rising demand did not translate into higher prices, which could reflect the high competition prevailing on the market. We rather provide evidence of lower prices: a 10 percent increase in the number of crossings led to a 4 percent decrease in smuggling fees. We rationalize this result using a simple monopolistic competition model with free entry wherein each smuggler operates on a route featuring unique non-price characteristics.

Abstract

This paper analyses how media reporting policies on crime impact natives’ attitudes towards immigration. We depart from most of the existing literature by investigating the content of crime-related articles instead of their coverage. Specifically, we use a radical change in local media reporting on crime in Germany, following hundreds of sexual assaults in Cologne on the 2015-2016 New Year’s Eve, as a natural experiment. This unique framework allows us to estimate whether systematically disclosing the origin of criminals affects natives’ attitudes towards immigration. Using individual survey data collected between January 2014 and December 2018 from the German Socio-Economic Panel and analysing more than 545,000 crime-related articles in German newspapers, and data on their diffusion across the country, we find that systematically mentioning the origin of criminals, especially when offenders are natives, significantly reduces natives’ worries about immigration.

Abstract

We study how satisfaction with government efforts to respond to the COVID-19 crisis affects compliance with pandemic mitigation measures. Using a novel longitudinal household survey for Germany, we overcome the identification and endogeneity challenges involved in estimating individual compliance by using an instrumental variable approach that exploits exogenous variation in two indicators measured before the crisis: political party preferences and the mode of information measured by the frequency of using social media and reading newspapers. We find that a one unit increase in subjective satisfaction (on the 0-10 scale) improves protective behavior by 2-4 percentage points. Satisfaction with the government’s COVID-19 management is lower among individuals with right-wing partisan preferences and among individuals who use only social media as an information source. Overall, our results indicate that the effectiveness of uniform policy measures in various domains, such as the health system, social security or taxation, especially during pandemic crises, cannot be fully evaluated without taking individual preferences for collective action into account.

Abstract

In this paper, we ask whether the main cause of asylum migration, that is, violence in the home country, still affects the life satisfaction of refugees even after they reach a safe country. We combine individual-level survey data on refugees in Germany with country-level data on terror fatalities. The timing of the survey interviews generates exogenous variation in the intensity of recent terror activity in respondents' countries of origin, which we exploit to assess the effect of terror fatalities on the level of self-reported life satisfaction. Our results indicate that fatalities due to terror activity reduce, on average, the level of life satisfaction reported by refugees. We find that this effect is most substantial for events occurring one or two days before the interview, while older events have no effect. However, we observe an effect of fatalities during the four weeks preceding the interview on persons who have a family member abroad. We show that the group of respondents with a rejected or pending asylum application without legal family reunification options mostly drives this effect.

Abstract

Immigration policy in most high-income countries is designed to promote qualified migration while maintaining high requirements on characteristics such as education and language skills. We rely on a standard self-selection model with heterogeneous migration costs to discuss the effect of access to language learning services in the country of origin on the skill composition of immigrants in Germany. Using individual-level survey data on immigrants from different cohorts over the period 2000 - 2014, combined with unique data on the presence of Goethe Institutes - a German association promoting German language and culture worldwide - in origin countries, the results of our empirical analysis show that the acquisition of the German language is fostered by the availability of language courses abroad. Moreover, we find that language services abroad induce a positive (self-)selection of migrants along several dimensions, such as education, experience, and the probability of holding a job offer at arrival. These characteristics are in turn highly relevant for long- term integration in Germany. To disentangle transmission channels, we perform a causal mediation analysis. We find that 25 % of the total effect of language services abroad on language skills at immigration trace back directly to migrants' participation in language courses, revealing important spillover effects.

(4) Natives’ Attitudes and Immigrants’ Unemployment Durations


with Jérôme valette. Demography (2019), 56(3):1023-1050. https://doi: 10.1007/s13524-019-00777-3.

Abstract

In this study, we investigate how the attitude of natives—defined as the perceived trustworthiness of citizens from different countries—affects immigrants’ labor market outcomes in Germany. Evidence in the literature suggests that barriers to economic assimilation might be higher for some groups of immigrants, but the role of natives’ heterogeneous attitudes toward immigrants from different countries of origin has received little attention. Using individual-level panel data from the German Socio-Economic Panel covering the years 1984 to 2014, we apply survival analysis methods to model immigrants’ unemployment durations. We find that lower levels of trust expressed by natives toward the citizens of a given country, measured using Eurobarometer surveys, are associated with increased unemployment durations for immigrants from this country. We show that this result is not driven by origin-specific unobserved heterogeneity and that it is robust to different specifications and alternative explanations.

(3) Give a fish or teach fishing? Partisan affiliation of U.S. governors and the poverty status of immigrants


with Pierre MandonEuropean Journal of Political Economy (2018), (55):65-96. https://doi.org/10.1016/j.ejpoleco.2017.11.004.

Abstract

This paper investigates how governors' partisan affiliation affects the poverty status of immigrants to the U.S. To this end, we compare the poverty outcomes of immigrants in states ruled by Democratic governors relative to the outcomes for those in states ruled by Republican governors. We employ a regression discontinuity design using the re-centered Democratic margin of victory as a running variable, to overcome the identification challenge posed by confounding factors. Consistent with the literature on partisan affiliation, we find that immigrants are more likely to get out of poverty in states with Democratic governors than states with Republican governors. Our results are submitted to a variety of robustness checks and sensitivity tests, to assess the validity of the identification strategy, and highlight conditional lame-duck effects. A formal mediation analysis reveals that the empirical results are mediated through better access to the labor market and possibly through higher wages and labor earnings for immigrants. Last but not least, we check for alternative hypotheses and potential detrimental effects for native populations.

(2) The Elasticity of the Migrant Labour Supply: Evidence from Temporary Filipino Migrants


with Simone Bertoli and Jesús Fernández-Huertas Moraga.The Journal of Development Studies (2017), 53(11), 1822-1834, DOI: 10.1080/00220388.2016.1219347.

Abstract

The effect of immigration on host and origin countries is mediated by the way migrants take their labour supply decisions. We propose a simple way of integrating the traditional random utility maximisation model used to analyse location decisions with a classical labour demand function at destination. Our setup allows us to estimate a general upper bound on the elasticity of the migrant labour supply that we take to the data using the evolution of the numbers and wages of temporary overseas Filipino workers between 1992 and 2009 to different destinations. We find that the migrant labour supply elasticity can be very large. Temporary migrants are very reactive to economic conditions in their potential destinations.

(1) Bilateral real exchange rates and migration

Abstract

Migrants who move across borders are, to a large extent, motivated by the prospect of earning higher incomes at destination, which can be partly transferred back to their countries of origin via remittances. This suggests that the real exchange rate can influence the incentives to migrate, as it determines the purchasing power of expected income in terms of the currency of the origin country. This article investigates empirically how bilateral real exchange rate fluctuations influence international migration flows. To do so, we build a dataset of 30 OECD destination countries and 165 origin countries over the period 1980–2011 and estimate an equation derived from a micro-founded random utility maximization model that allows for unobserved heterogeneity between migrants and non-migrants. Our results show that migration flows are highly responsive to bilateral real exchange rates: A 10% real appreciation of the currency of the destination country is associated with an 18.2–19.4% increase in migration flows.
