Feudal Incomes and Demand Elasticity for Bread in Late Eighteenth-Century France

The works of Labrousse and Chabert on income fluctuations in pre-and post-revolutionary France have already been subjected to abundant criticism by Professor Landes in the November 1950 issue of THE JOURNAL OF ECONOMIC HISTORY. The present note results from an attempt at resolving in a constructive way certain of the contradictions observed between Labrousse's inferences and his data. The argument, originally developed on the basis of observations in the decade immediately preceding the French Revolution, was extended to cover the thirty years (1815-1845) following the fall of Napoleon's empire. After a short review of Labrousse's “grain crop” interpretation of French economic cycles, it is shown that (1) his computations of feudal revenues do not agree with his description of their cyclical pattern and (2) grain revenue figures are only consistent with an elastic demand for bread over a certain range. This squarely contradicts the inelasticity assumption which underlies both Labrousse's theory and Landes' criticism of it. The treatment of eighteenth-century bread demand as price-inelastic had already wide currency among contemporary economists, and does not seem to have been seriously challenged ever since. An inductive analysis supported by scattered pieces of empirical evidence is then developed, with the conclusion that demand for bread (and grain) should indeed be elastic over the relevant region. The last section represents an extension of this interpretation to crop and price data in the post-Napoleonic period.
