This article studies inequality in Buenos Aires from the late colonial period to the beginning of the belle époque through series of prices based on primary sources. This enables a comparison of the evolution of land prices and wages in order to estimate the functional income distribution among workers and proprietors. The evolution of livestock prices is assessed as well to capture a more complete image of capital income, due to the importance of cattle raising for the economy of Buenos Aires. The outcome reveals an increasing inequality since the dawn of the cattle-farming boom at the beginning of the independent era.
