Resumo

We prove the existence of stationary equilibrium in the primary and secondhand markets for an indivisible consumer durable in a general model with stochastic degradation and endogenous scrappage decisions. Unlike Rust (Econometrica 53 (1985) 783), we introduce transaction costs in the model as a motivation for consumer holdings of durables across multiple quality levels. Our technique allows for both multiple types of durables (e.g., Porsche and BMW) and relaxation of the single-crossing condition on consumer tastes. We provide a simple example showing how increasing transaction costs affect secondhand prices, eventually (for sufficiently costly transactions) closing the secondhand market altogether.
