Intro and literature Empirical approach Results Conclusion

Motivation

The relationship between migration and trade has been studied for so long Migrants’ contribution to exchange involve different causal mechanisms that remain unclear Pro-trade effect is likely motivated by the way ethnic networks solve information problems Causal inference requires convincing identification strategies to sort out endogeneity

trade relationships and migration decisions are potentially explained by common ‘unobserved’ shocks, and reverse causality

Intro and literature Empirical approach Results Conclusion

Idea

We study the causal effect of a large migration shock into Spain exploiting the distribution of foreign born population per country of birth across provinces on export extensive margin by local firms Fixed cost-per product and fixed cost per transaction are common trade barriers We test if ethnic networks reduce the burden of regulations on the extensive margin of trade Identification

Interaction between origin-specific push factors and destination-specific pull factors generates a quasi-random variation in the allocation of migrants across Spanish provinces (Burchardi et al, 2018)

We use migration inflows over two decades 1991-2011 to 50 provinces and from 179 foreign countries and transaction level export data from province to each foreign country in 2015

Intro and literature Empirical approach Results Conclusion

Literature

Affinity between regions (social ties, trust, common ancestry, etc) correlate strongly with aggregate outcomes such as trade flows (Gould, 1994), FDI (Guiso, Sapienza and Zingales, 2009) and international assets flows (Portes and Rey, 2005) Several papers have attempted to assess the causal impact of migrations

  • n trade and FDI using instrumental variables: Javorcik et al. (2011) use

cost of acquiring a passport for the migration-FDI relationship; Cohen et

  • al. (2015) use the location of Japanese internment camps during the

WWII to infer trade flows between locations within the US and Japan; Parsons and Vezina (2016) use the placement of Vietnamese refugees after the Vietnam War to infer trade flows with Vietnam Nevertheless, in the last two papers instrumenting for migration from one country makes impossible to control for destination fixed effects

Literature (cont’)

Peri and Requena-Silvente (2010) estimate a migration-trade causal effect for Spanish provinces relying on a Card (2001) instrument that might not be suitable in this context. Indicate strong extensive-margin effect of ethnic network Burchardi, Chaney and Hassan (2018) present a novel approach yielding a specific instrument for migrations from each origin to each destination at each point in time and allowing to control simultaneously for both origin and destination fixed effects Hornok and Koren (2015) and in Kropf and Saur´ e (2014) present theory and evidence of how administrative barriers to trade affect disproportionally the extensive margins of trade

Intro and literature Empirical approach Results Conclusion

Theory

Trade frictions are large especially for poor countries (Anderson and van Wincoop, 2004). Migrants may have a positive effect on trade costs because

its contribution to equalize preferences in consumption across countries they provide social collateral for contract enforcement, replacing weak institutions they reduce information frictions related to a country’s language, regulations, market opportunities and informal institutions

Similar mechanisms are established for FDI or international business

Model

Our goal is to estimate an equation like the following: To,d = αo + αd + δM2011

  • ,d

+ X ′

  • ,d + ǫo,d

(1) where To,d is a trade variable (i.e., exports) measuring either the number of transactions (shipments) or the number of products exported to the origin country, o from the destination region, d of migrants in the year 2015. Mo,d is a measure of the extent of the ethnic network residing in region d with origin in country o in 2011, measured as the log of 1 plus units of foreign born resident. X ′

  • ,d is a vector of control variables normally included in the gravity-type
  • f models, including the geographic distance between o and d, and

difference in latitude between o and d

Extended model

We include a new interaction variable to the model (1): To,d = αo + αd + δM2011

  • ,d

+ γM2011

  • ,d

× barriero + X ′

  • ,d + ǫo,d (2)

where barriero is an indicator variable taking value 1 when country

  • trade barrier is above world average

γ coefficient tests whether migration effect of trade is higher at the most regulated economies

The instrument is based on a dynamic equation of the form: Mt

  • ,d + I t
  • ct

  • ,d

(3) where the constant terms, at, ao,t, and ad,t control for residual forces, such as demographics, which may vary over time, over space, and between different ethnic groups. The term btMt−1

  • ,d reflects the strength of the migration stock to

attract new migrants with the same origin and destination being bt the parameter that modulates this intensity. Io measures the push factor common to all migrants with the same origin entering into Spain between t and t − 1. ct

It measures the the degree to which province o is particularly appealing to

  • migrants. The fraction of migrants from country o who already lives in

province d, dt

  • countrymen. Coefficients, ct and dt control for the relative importance of the

pull and recursive factors.

We count as immigrants the residents of the province d born in a foreign country o, Mt

We calculate the net flows of immigration in the intercensal period 1991-2001, Io,d, as the difference between the stock of immigrants

Migration main figures

Unlike migrations to the United States that date back to the 19th century, emigration to Spain is quantitatively a recent phenomenon Average foreign born residents at province-country pair (50–179) level went from 87 in 1991, to 653 in 2011 The wave of mass immigration to Spain has been a generalized shock in all provinces and from all origins

Trade Data

Trade data is from Agencia Tributaria file of the 2015 edition It contains information about each international shipment that has its

  • rigin or destination in Spain

Recorded variables: date of shipment, product code, value and weight, countries of destination or origin and transit, and the details of the shipment, such as the form of transport, the ship’s flag and if the cargo is in a container Product classification is at eight-digit Combined Nomenclature We aggregate trade variables for each pair of province of origin of the shipment and the country of destination We obtain the following extensive margin trade indicators: the number of shipments and the number of products exported

Intro and literature Empirical approach Results Conclusion Channels of influence

Reconciling theory and evidence

Evidence indicates that ethnic networks facilitate firms trade adjustment through the extensive margin by changing the number of products and/or the number of shipments This is consistent with the hypothesis that migrants reduce information frictions that impede trade (i.e., Burchardi et al. (2018) find similar evidence for FDI) Relevant trade barriers are likely product–shipment specific fixed costs, as in Hornok and Koren (2015) or in Kropf and Saur´ e (2014) We test this hypothesis using data of administrative barriers to trade from the Doing Business Report

Reconciling theory and evidence (cont’)

Doing Business provides measures for the time and cost (excluding tariffs) associated with three sets of procedures -border compliance, documentary compliance and domestic transport- within the overall process of exporting and importing a shipment of

  • goods. E.g., border compliance:

1 Includes the following items: (a) hire a custom broker, (b)

conduct a pre-shipment inspection by customs, (c) process the import declaration, (d) complete documents check, scanning/weighing and physical inspection by customs, (d) pay customs administrative fees, (e) any additional procedure

2 Procedures conducted by agencies other than customs: any

kind of technical, pre-shipment or security inspection
