Temporary Protection and Technology Adoption: Evidence from the Napoleonic Blockade - Job Market Paper

Industrial policy is always a contentious argument in development economics between free-marketers and state intervention. Réka Juhász's Job Market Paper "TemporaryProtection and Technology Adoption: Evidence from the Napoleonic Blockade" brings historical evidence to that debate through an interesting natural experiment from the early 19th century.

Abstract

"This paper uses a natural experiment to assess whether temporary protection from trade with industrial leaders can foster development of infant industries in follower countries. Using a new dataset compiled from primary sources, I find that in the short-run regions (départements) in the French Empire which became better protected from trade with the British for exogenous reasons during the Napoleonic Wars (1803-15) increased capacity in a new technology, mechanised cotton spinning, to a larger extent than regions which remained more exposed to trade. Temporary protection had long term effects. In particular, by exploiting the fact that the post-war location of the cotton industry was determined to a large extent by the historical accident of the wars, I first show that the location of cotton spinning within France was persistent, and firms located in regions with higher post-war spinning capacity were more productive 30 years later. Second, I find that after the restoration of peace, exports of cotton goods from France increased substantially, consistent with evolving comparative advantage in cottons. Third, I show that as late as 1850, France and Belgium - both part of the French Empire prior to 1815 - had larger cotton spinning industries than other Continental European countries which were not protected from British trade during the wars; this suggests that adoption of the new technology was far from inevitable."

Interestingly, the paper studies the effects of an event and policy that was not designed for industrial purposes: the Napoleonic Wars and the Continental Blockade. While the Continental Blockade had the foreign policy purpose of undermining Britain's trade advantage/power and not necessarily a protectionist measure for French industry (in this case cotton). Probably the most interesting case may be that of Belgium and not that of France. During the Napoleonic Wars, Belgium was under French control (1794-1815) until it became part of the Netherlands. However, cotton industry grew more in Belgium than in the Netherlands in the post-Napoleonic period.. pointing out to the second issue: Technology Adoption

The results show there may be some role to be played for protectionist policies for infant industries not only to establish productive capacity but also the be able to adopt/adapt new technologies more successfully. On the other hand, the temporary protection was not sector-specific but across the board, leading to the interpretation that industrial policy may be more effective by focusing on the general environment rather than specific industries, allowing for an efficient internal reallocation of resources.

To note that the study focuses on a successful case and does not look at the industries that may have been wiped out after the lifting of the blockade, so we should be careful in making general economic welfare interpretations at country level.
