Details

The structure of the dataset is such that the time index runs “fast”, while the firm index runs “slow”; that is, first all 14 observations for the first firm are given, then the 14 observations for the second firm, etc.

Since we used one year lagged variables of "vala", "debta", "cfa" and "cfa" as regressors, the records in 1973 are skipped.

All values are nominal and millions of dollars except where otherwise noted. Stocks are end of year.
