Résumé This paper asks whether macroeconomic policy can affect fertility and education by documenting a slow-down of long-term improvements in these two outcomes in the wake of a major protectionist shock that shielded low-skilled individuals from the adverse consequences of the first wave of globalisation. We build a novel dataset for 19th-century France where, following decades of rising grain imports at low prices, high tariffs on cereal were introduced in 1892, shifting relative prices in favour of agriculture and away from industry. We exploit regional data that allow us to measure differences in the intensity of the protectionist shock and find that the tariff halted the long-term increase in schooling and slowed-down the decline in fertility that were already well underway.

Résumé How have societies coped with large increases in public debt? in the European history of the last three centuries, these moments have occurred mainly during and after wars, with the notable exception of the end of the 19th century and the end of the 20th century. these increases have had contrasting consequences both in terms of macroeconomic consequences and in terms of the solutions implemented to reduce these debt bumps. a distinctive element between these 20th century episodes and those of the 18th and 19th centuries was the use of financial engineering to smooth out the debt jumps, making it possible to “buy the time” necessary, in any post-war period, to restore macroeconomic equilibrium.

Résumé The long-term costs of protectionism are difficult to evaluate as very few countries have switched back to this economic policy after a long period of free trade. One country that did make the move was France in 1892, when the Chamber of Deputies, encouraged by the president of the customs commission, Jules Méline, decided to sharply raise cereal import duties. This decision slowed the upwards trend in education levels as it made farming jobs more attractive than manufacturing jobs, thereby reducing the relative return on an education. These findings are consistent with the theory of unified growth which associates demand for education with technological improvement. They also suggest that educational progress is reversible.

Résumé This paper analyzes how collateral quality shocks affect banks' liquidity management and the risk-free rate. We develop a model where banks manage liquidity through near-cash assets and marketable securities subject to idiosyncratic and/or aggregate shocks. Collateral quality deterioration leads to non-monotonic changes in liquidity holdings: moderate declines reduce cash holdings via lower market returns, while severe declines cause precautionary hoarding and market freezes. Reduced collateral quality depresses the risk-free rate. Policy interventions, including liquidity regulation and negative interest rate policies can mitigate these effects. Our findings highlight the risks of collateral quality shocks and the importance of policy complementarities in addressing liquidity issues.

Résumé This paper examines a novel negative impact of trade tariffs and the costs they induce by documenting how protectionism reversed the long-term improvements in education and the fertility transition that were well under way in late 19th-century France. The Méline tariff, a tariff on cereals introduced in 1892, was a major protectionist shock that shifted relative prices in favor of agriculture and away from industry. In a context in which the latter was more intensive in skills than agriculture, the tariff reduced the relative return to education, which in turn affected parents' decisions about the quantity and quality of children. We use regional differences in the importance of cereal production in the local economy to estimate the impact of the tariff. Our findings indicate that the tariff reduced enrolment in primary education and increased birth rates and fertility. The magnitude of these effects was substantial, with the tariff offsetting the increasing trend in enrolment rates and the decreasing one in birth rates by a decade.

Résumé The assumption that education and fertility are endogenous decisions that react to economic circumstances is a cornerstone of the unified growth theory that explains the transition to modern economic growth, yet evidence that such a mechanism was in operation before the 20th century is limited. This paper provides evidence of how protectionism reversed the education and fertility trends that were well under way in late 19th-century France. The Méline tariff, a tariff on cereals introduced in 1892, led to a substantial increase in agricultural wages, thus reducing the relative return to education. Since the importance of cereal production varied across regions, we use these differences to estimate the impact of the tariff. Our findings indicate that the tariff reduced education and increased fertility. The magnitude of these effects was substantial, and in regions with large shares of employment in cereal production the tariff offset the time trend in education for up to 15 years. Our results thus indicate that even in the 19th century, policies that changed the economic prospects of their offspring affected parents’ decisions about the quantity and quality of children.
