The Historical and Expected Equity Risk Premium in Spain: A Long-Run View, 1900-2020

We present revised estimates of the historical (ex post) equity risk premium and an original estimate of the expected (ex ante) premium for the Madrid stock market over a period of 120 years. The results are based on a new equity index, the H-IBEX (1900-1987), built on high-quality monthly data hand-collected from primary sources and methodologically aligned with the modern Spanish index, IBEX35.

We also reconstructed an original weighted index of government bonds (1900-1987) which can be smoothly connected with recent data. Data include original series for equities, bonds and bills for the Madrid Stock Exchange from 1900 to 1987, at monthly and annual frequency, spliced with more recent data on equities (IBEX35) and bonds, to cover the period until 2020. Documentation includes three Excel files (monthly series, annual series and summary of annual data) and one Eviews13 file with main regressions. | Equities and bonds traded in the Madrid Stock Exchange.
