The measurement of mining land rent in Chile and its appropriation courses (1940-2017)

In this paper, we present the foundations and results for a new rent database on mining land in Chile (1940-2017), which takes into account not only the surplus profits of the sector, but also the different mechanisms in which this land is appropriated by other social actors. The results are weighted in relation to the whole national economy, which is why an original time series of the general rate of profits and its components, surplus-value and total advance capital, is also provided. In this paper, we posit a methodological foundation based on Marx's developments and a critical review of the existing statistics and previous measures. The results are original as they are the first long-run time series of mining land rent which considers the main appropriation mechanisms by different social actors. In turn, it shows that previous studies underestimate the weight of mining land rent in the Chilean economy, particularly when the prices of copper are rising. In addition, the results make it possible to pose new questions regarding the development of the national specificity considered. As a result of this new evidence, we indicate specific determinations of the different political cycles in Chilean national life, showing the historical persistency of mining land rent beyond changes in its appropriation forms and, therefore, stepping outside of the import substitution industrialization and neoliberalism dichotomy, which dominates the long-run economic historiography in this country.
