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

with Juan Carluccio, Alejandro Cuñat and Christian Fons-Rosen, September 2015.
Featured in a Vox column

We present a factor proportion trade model in which heterogeneous firms can offshore intermediate inputs subject to fixed offshoring costs. In the skill-abundant country, high-productivity firms offshore a larger range of labor-intensive inputs to labor-abundant countries than low-productivity firms. Differently from the traditional versions of factor proportions trade theory, Heckscher-Ohlin forces operate at the within-industry level, leading to variation in skill intensity across firms that orrelates positively with firm productivity. Using French firm-level data for the years 1996 to 2007, we provide empirical support for the factor proportions channel through which offshoring to labor-abundant countries affects the firm-level skill intensities of French manufacturers.

Income Differences and Input-Output Structure

with Mariya Teteryatnikova and Christian Ghiglino, September 2015.

We consider a multi-sector general equilibrium model with IO linkages, sector-specific productivities and tax rates. Using tools from network theory, we investigate how the IO structure interacts with productivities and taxes in the determination of aggregate income. Employing a statistical approach, we show that aggregate income is a simple function of the first and second moments of the distribution of the IO multipliers, sectoral productivities and sectoral tax rates. We then estimate the parameters of the model to fit their joint empirical distribution, allowing these to vary with income per capita. We find an important difference between rich and medium-low income countries. Poor countries have more extreme distributions of IO multipliers than rich economies: there are a few high multiplier sectors, while most sectors have very low multipliers; in contrast, rich countries have more sectors with intermediate multipliers. Moreover, the correlations of these with productivities and tax rates are positive in poor countries, while being negative in rich ones. The estimated model predicts cross-country income differences extremely well, also out-of-sample (up to 97% of the variation in relative income per capita). Finally, we perform a number of counterfactuals. First, we impose the dense IO structure of the U.S. on low- and middle-income countries and find a large damaging effect, up to 80 %. Second, we assume that sectoral IO multipliers and productivities are uncorrelated and find that low-income countries would lose up to 50% of their per capita income while high-income countries would gain.

Do Prices Determine Vertical Integration?

with Laura Alfaro, Paola Conconi and Andrew Newman.
Review of Economic Studies, forthcoming

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.


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.

TTIP - eine Analyse aus europäischer Perspektive

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.
