Contributed by Marvin Lieberman

The data describe 41 homogeneous, commodity-type chemicals or related products, between 1948 and 1983. In total, the data set consists of product level information for 1,177 product-years, with an average observation period of 28 years (Data File 1), firm-level data indicating which products each firm produced (Data File 2), and plant-level capacity data by product and firm for the aforementioned chemical industry products (Data Files 3 and 4).

Different articles by Lieberman (see Author’s Research Using This Data Set, below) use various subsets of the data, and some products in these articles are not included in the FIVE data.
