Details

These data are a subset of a table in Boot and de Wit (1960), also known as the Grunfeld data. It is used a lot in econometrics, e.g., for seemingly unrelated regressions (see SURff).

Here, $P_1 =$ Implicit price deflator of producers durable equipment (base 1947), $P_2 =$ Implicit price deflator of G.N.P. (base 1947), $P_3 =$ Depreciation expense deflator = ten years moving average of wholesale price index of metals and metal products (base 1947).
