A dataset containing a balanced panel data of annual observations over the period 1973-1987 (15 years) for 560 US firms for the variables described below.
A tibble with 7840 rows and 20 variables:
Committee on Uniform Security Identication Procedures firm code number, the first 6 digits (CNUM)
2-digit year of the data
investment to assets ratio
dummy variable for 1975
dummy variable for 1976
dummy variable for 1977
dummy variable for 1978
dummy variable for 1979
dummy variable for 1980
dummy variable for 1981
dummy variable for 1982
dummy variable for 1983
dummy variable for 1984
dummy variable for 1985
dummy variable for 1986
dummy variable for 1987
lagged total market value to assets ratio ("Tobin's Q")
lagged long term debt to assets ratio
lagged cash flow to assets ratio
lagged sales during the year (million USD)
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.
