The Real Exchange Rate, Innovation and Productivity

with Laura Alfaro, Alejandro Cuñat and Yanping Liu, November 2017.

We evaluate manufacturing firms' responses to changes in the real exchange rate (RER) using detailed firm-level data for a large set of countries for the period 2001-2010. We uncover the following stylized facts: In emerging Asia, real depreciations are associated with faster growth of firm-level TFP, sales and cash-flow, higher probabilities to engage in R&D and export. We find no significant effects for firms from industrialized economies and negative effects for firms in other emerging economies, which are less export-intensive and more import-intensive. Motivated by these facts, we build a dynamic model in which real depreciations raise the cost of importing intermediates, but increase demand and the profitability to engage in exports and R&D, thereby relaxing borrowing constraints and enabling more firms to overcome the fixed-cost hurdle for financing R&D. We decompose the effects of RER changes on productivity growth into these channels and explain regional heterogeneity in the effects of RER changes in terms of differences in export intensity, import intensity and financial constraints. We estimate the model and quantitatively evaluate the different mechanisms by providing counterfactual simulations of temporary real exchange rate movements. Effects on physical TFP growth, while different across regions, are non-linear and asymmetric.

Offshoring and Skill-Upgrading in French Manufacturing: A Heckscher-Ohlin-Melitz View

with Juan Carluccio, Alejandro Cuñat and Christian Fons-Rosen, new version, September 2016, submitted.
Featured in VOX, in Rue de la Banque and in Le Figaro.

Using French manufacturing firm-level data for the years 1996 to 2007, we uncover a novel set of stylized facts about offshoring behavior: (i) Low-productivity firms obtain most of their inputs domestically. (ii) Firms with higher productivity offshore skill-intensive inputs to skill-abundant countries and are more labor intensive than non-importers in their domestic production. (iii) Firms with even higher productivity also import labor-intensive inputs from labor-abundant countries and are more skill intensive than non-importers. Inspired by these findings, we produce a model in which heterogeneous firms, subject to fixed costs, can offshore intermediate inputs of different skill intensities to countries with different skill premia. Heckscher-Ohlin-like forces operate at the within-industry level, leading to endogenous variation in domestic skill intensities across firms. We provide econometric evidence supporting the factor-proportions channel through which reductions in offshoring costs to labor-abundant countries have increased firm-level skill intensities of French manufacturers.

We study the role of input-output (IO) linkages and sectoral productivity (TFP) levels for cross-country income differences. Using data on IO tables and sectoral TFPs, we fond important differences in IO structure and its interaction with TFP levels across countries: while highly connected sectors are more productive than the typical sector in poor countries, the opposite is true in rich ones. To quantitatively assess the role of IO linkages in cross-country income differences, we use tools from network theory to build a multi-sector general equilibrium model. Aggregate income is approximated by a simple function of the first and second moments of the joint distribution capturing interactions of IO linkages and sectoral TFPs. We then structurally estimate country-specifc parameters of this distribution and simulate cross-country income differences. Our main finding is that incorporating IO linkages into a model with sectoral TFP differences significantly improves our ability to predict cross-country income variation.

Come Together: Firm Boundaries and Delegation

with Laura Alfaro, Nick Bloom, Paola Conconi, Patrick Legros, Andrew Newman, Raffaella Sadun and John Van Reenen.

Little is known theoretically, and even less empirically, about the relationship between firm boundaries and the allocation of decision rights within firms. We develop a model in which firms choose which suppliers to integrate and whether to delegate decisions to integrated suppliers or keep them centralized. We test the predictions of this model using a matched dataset that combines measures of vertical integration and delegation for a large set of firms operating in many countries and industries. In line with the model's predictions, we find that integration and delegation co-vary, and that producers are more likely to integrate suppliers in input sectors with greater productivity variation.

Do Prices Determine Vertical Integration?

with Laura Alfaro, Paola Conconi and Andrew Newman.
Review of Economic Studies, 2016, 83 (3), pp. 855-888 (lead article).

A number of theories in organizational economics and industrial organization suggest that vertical integration, while costly, increases productivity. It follows from firms' maximizing behaviour that higher prices in the product market ought to induce more integration. Trade policy provides a source of exogenous price variation to assess this prediction: higher tariffs should lead to higher prices and, therefore, to more integration. We construct firm-level vertical integration indices for a large set of countries and industries and exploit variation in applied most-favoured-nation tariffs to examine the impact of tariffs on firm boundaries. The empirical results provide strong support for the view that higher output prices generate more vertical integration. Our estimates of the average price elasticity of vertical integration are in the range 0.4-2.

Skill-biased Technological Change, Unemployment and Brain Drain

with Karin Mayr. Journal of the European Economic Association, 2014, 12(2), pp. 397-431.

We develop a model of directed technology adoption, frictional unemployment and migration to examine the effects of a change in skill endowments on wages, employment rates and emigration rates of skilled and unskilled workers. We find that, depending on the elasticity of substitution between skilled and unskilled workers and the elasticity of the matching function, an increase in the skill ratio can reduce the relative unemployment rate of skilled workers and decrease the relative emigration rate of skilled workers (brain drain). We provide empirical estimates and simulations to support our findings and show that effects are empirically relevant and potentially sizable.

Trade Policy: Home Market Effect versus Terms-of-Trade Externality

with Alessia Campolmi and Chiara Forlati.
Journal of International Economics, 2014, 93(1), 92-107.

We study trade policy in a two-sector Krugman (1980) trade model, allowing for wage, import and export subsidies/taxes. We study non-cooperative trade policies, first for each individual instrument and then for the situation where all instruments can be set simultaneously, and contrast those with the efficient allocation. We show that in this general context there are four motives for non-cooperative trade policies: the correction of monopolistic distortions; the terms-of-trade manipulation; the delocation motive for protection (home market effect); the fiscal-burden-shifting motive. The Nash equilibrium when all instruments are available is characterized by first-best-level wage subsidies, and inefficient import subsidies and export taxes, which aim at relocating firms to the other economy and improving terms of trade. Thus, the dominating incentives for non-cooperative trade policies are the fiscal-burden-shifting motives and terms-of-trade effects.

Incomplete Contracts, Learning and Export Dynamics: Theory and Evidence from French Firms

with Romain Aeberhardt and Ines Buono
European Economic Review, 2014, 68, pp. 219-249.

We consider a model in which exporting requires finding a local partner in each market. Contracts are incomplete and exporters must learn the reliability of their partners through experience. Export behavior is state-dependent due to matching frictions. Better legal institutions alleviate contracting frictions especially in sectors with large contracting problems, thereby increasing state dependence and reducing hazard rates by more in those sectors. Moreover, hazard rates decline with the age of the relationship, as unreliable partners are weeded out. We find strong evidence in favor of the model's predictions when testing them with French firm-level data.

Trade and Sectoral Productivity

Cross-country differences in sectoral total factor productivity (TFP) are at the heart of Ricardian trade theory and of many models of growth and development. Our knowledge of the magnitude and the characteristics of cross-country differences in sectoral TFP is still limited however. This study fills the gap by showing how sectoral TFP differences can be backed out from bilateral trade data using a hybrid Ricardo-Heckscher-Ohlin model. This approach allows us to overcome the data problems that constrained previous studies and to provide a comparable set of sectoral productivities for twenty-four manufacturing sectors in more than sixty countries at all stages of development. Our results imply that TFP differences in manufacturing sectors between rich and poor countries are substantial and far more pronounced in skilled labor and R&D intensive sectors than in others. We also apply our productivity estimates to test development theories that have implications for cross-country industry-level productivity patterns.

Productivity Differences in an Interdependent World

Journal of International Economics, 2011, 84 (2), pp. 221-232.
» Supplementary Appendix

This paper studies cross-country differences in productivity from an open economy perspective by using a Helpman-Krugman-Heckscher-Ohlin model that embraces the single-cone model and a one-sector economy with factor deepening as particular cases. To estimate the model, I combine tools from development accounting and the factor content of trade literature. When simultaneously fitting data on income, factor prices and the factor content of trade, I find that the one-sector model is by far better supported by the data than the single-cone model. Rich countries have far higher productivities of human capital than poor ones, while differences in physical capital productivity are not related to income per worker. Finally, I estimate an aggregate elasticity of substitution between human and physical capital that is significantly below one.

The Micro-Dynamics of Exporting: Evidence from French Firms

with Ines Buono. Banca d'Italia - Temi di Discussione, 2012, Nr. 880.

This paper investigates the dynamics of export relationships -- defined as shipments by a given firm to a given destination in a given year -- using a panel of almost 25,000 French exporters over the five-year period 1995-1999. We describe how these export relationships evolve over time and present a number of stylized facts, which we relate to different theories of export dynamics, such as a dynamic sunk-cost model and the recent literature on exporting and learning.
We find that export relationships are very dynamic: a large fraction of export relationships are created or destroyed every year and export values within relationships fluctuate substantially. Most of these dynamics are explained by relationship-specific shocks rather than by supply and/or demand shocks. Moreover, upon entry, export values are small but they gradually expand as relationships mature. Finally, while many export relationships are volatile, others are persistent. Having previously exported to a given destination substantially increases the probability of exporting there in the current period. We argue that, taken together, these facts are more in line with a learning model than with the sunk-cost hypothesis.

Les gagnants et les perdants de la mondialisation : la délocalisation profite aux travailleurs qualifiés et nuit aux travailleurs moins qualifiés. (Winners and losers from globalization: offshoring benefits skilled workers and hurts unskilled workers)

with Juan Carluccio, Alejandro Cunat and Christian Fons-Rosen. Rue de la Banque 51, Banque de France, November 2017.

Ce Rue de la Banque, fondé sur l'exploitation de données détaillées relatives à l'industrie manufacturière francaise, démontre que la délocalisation vers des pays à bas salaires a largement déterminé la situation des travailleurs peu qualifiés sur le marché du travail en France au cours de la période allant de 1995 à 2007. Les résultats confirment la vision largement répandue selon laquelle le commerce international engendre des gains de productivité, en permettant notamment d'obtenir des biens intermédiaires moins chers, ces gains n'étant toutefois pas répartis de facon égale entre les différents acteurs économiques. Pour tirer le meilleur parti de la mondialisation, il est par conséquent nécessaire de mettre en oeuvre des politiques publiques, en matière notamment de formation professionnelle afin d'accompagner la transition vers des emplois plus qualifiés.

Input-output linkages and income differences across countries: New evidence

with Christian Ghiglino and Mariya Teteryatnikova. www.voxeu.org, 24 December 2016.

Economists are just starting to understand how observed input-output linkages and productivity differences are connected. This column investigates how differences in the distribution of sectoral input-output multipliers interact with sectoral productivities to determine cross-country differences in aggregate income. It finds that the impact of the linkages on productivity are substantial, which in turn has significant implications for policy.

Offshoring and unskilled labour demand: new evidence

with Juan Carluccio, Alejandro Cunat and Christian Fons-Rosen. www.voxeu.org, 14 December 2015.

The increase in the skill premium - wages of skilled workers relative to unskilled workers - has prompted research on its causes and potential remedies. This column presents new evidence suggesting that the impact of globalisation on the income distribution in industrialised countries is much stronger than initially thought. The productivity gains from having access to cheaper inputs through offshoring are not being distributed equally between the different economic actors in our rich societies.

Policy article on the economic effects of TTIP for the Austrian Society for European Politics (in German). OeGfE Policy Brief, 2015.08, 26 February 2015. Also featured on euractiv.de

Der vorliegene Policy Brief argumentiert, dass die direkten ökonomischen Effekte von TTIP unsicher sind und diese sich erst über einen Zeitraum von 10 bis 20 Jahren einstellen würden. Trotzdem handelt es sich um ein wichtiges strategisches Projekt, da TTIP gleichzeitig die bilateralen Beziehungen zu den USA stärken und neue internationale Standards für Freihandelsabkommen schaffen würde. Damit könnten potentiell Produkt-, Umwelt-, und Investitionsstandards in vielen Teilen der Welt positiv beeinflußt werden.

Firm organisation: What we know and why we should care

with Laura Alfaro, Paola Conconi, Patrick Legros and Andrew Newman. www.voxeu.org, 02 December 2012.

Increasingly, people are pointing the finger of blame for economic woe at large firms. This column argues that organisation design is often affected by government trade policy. If firm organisation design has implications for consumer welfare (in terms of prices and quality of product), evidence suggests that governments should make sure that in future, trade policy and corporate governance policy are more complementary.
