Habits And Durability In Consumption And The Effects Of Exchange Rate Policies

The effects of exchange rate policies are worked out in a model in which consumption goods are durable, and money enters the utility function. The interaction of habits and durability results in a non-monotonic adjustment of consumption expenditures, and the current account. As money does not exhibit durability, its dynamics are montonic, and determined mainly by habits effects. Hence, an increase in the rate of depreciation of the domestic currency will very likely lead to a nomonotonic adjustment of consumption and the current account, while the adjustment of real money holdings will be monotonic [F31, F32, F41]
