We provide a simple theory of in.ation inertia in a staggered price setting framework a la Calvo (1983). Contrary to Calvo.s formulation, the frequency of price changes is allowed to vary according to an evolutionary criterion. Inertia is the direct result of gradual adjustment in this frequency...

This paper analyzes the equilibrium dynamics of and optimal growth model that incorporates endogenous depreciation, variable capital utilization, and expenditures on the maintenance of physical capital. Maintenance acts as a substitute for investment, since it reduces the depreciation of...

This paper examines how a scrappage subsidy affects the lifetime of durable goods when secondhand markets are present. To this end, we propose a vintage model to analyze the replacement decision in an economy in which high and low income agents trade on a durable good. Thus, the existence of a...

We construct a two-sector vintage capital model with neutral and investment-specific technical progress and variable utilization of each vintage. The lifetime of capital goods is endogenous and it relies on the associated maintenance costs. First, we show that the lifetime of capital is an...

We construct a vintage capital à la Whelan (2002) with both exogenous embodied and disembodied technical progress, and variable utilization of each vintage. The lifetime of capital goods is endogenous and it relies on the associated operation costs. Within this model, we identify the rate of...
