Abstract: | This paper examines the general equilibrium effects of anticipated and unanticipated inflation shocks when an asset such as housing is financed by long-term contracts. Unlike other analyses of housing and mortgage finance, this model specifies that financial markets are fully integrated. Within a simple three-period overlapping generations model, agents obtain a mortgage in the first period and maximize utility under the constraint that no borrowing for consumption is allowed. Following inflation shocks, transition paths of endogenous interest rates, house prices, and welfare can be traced in simulations of the economy under the assumption of rational expectations. When nominal contracts prevail, an unexpected increase in the inflation rate causes a decline in the real rate of interest, owing to adjustments in the loanable funds market. Thus, real effects emerge even in the absence of tax distortions or explicit modelling of uncertainty. I contrast these real effects, given loans in the form of adjustable rate mortgages, with the absence of such effects when loans are price-level-adjusted mortgages. |
