Estimating (1) the relationship between currency valuations relative to gold and price level changes, and (2) real exchange rates in interwar European countries

Here I publish the underlying data and my following calculations: (1) the least-squares regression equation, in which cost-of-living indices in 1938 relative to 1929 (y-axis) are regressed on currency values in 1938 relative to their pre-crisis gold parities in 1929 (x-axis); and (2) cost-of-living index–based real exchange rates against the British pound.
