Simulation of clustering with firm and time effects.

Description

A dataset containing the 500 simulated firms over 10 years. Originally created by Mitchell Petersen in conjunction with Petersen (2009) and made available at http://www.kellogg.northwestern.edu/faculty/petersen/htm/papers/se/test_data.txt. See the references for simulation process. The variables are as follows:

Format

A data frame with 5000 rows and 4 variables

Details

• firmid. Firm identifier.

• year. Year identifier.

• x. Independent (right-hand side) variable.

• y. Dependent (left-hand side) variable.
