Context Data set from Aguirregabiria and Mira's 2008 survey paper on dynamic discrete choice models. This data was originally used in Rust's 1987 paper on bus engine replacement. The paper analyzes a bus company's decisions to replace bus engines. Rust's analysis shows that the bus company considers the future when making decisions. Content The data is just the data from Aguirregabiria and Mira's data.
