The unique characteristics of bank loans emerge endogenously to enhance efficiency in a model of renegotiation between a borrower and a lender in which there is the potential for moral hazard on each side of the relationship. Firm risk is endogenous and renegotiated interest rates on the debt need not be monotone in firm risk. The initial terms of the debt are not set to price default risk but rather are set to efficiently balance bargaining power in later renegotiation. Loan pricing may be nonlinear, involving initial transfers either from the borrower to the bank or from the bank to the borrower.

A stylized fact associated with inventory behavior is that the variance of production exceeds the variance of sales. This paper presents a model of production decisions with demand uncertainty that incorporates nonnegativity constraints on inventories. Even with no productivity shocks, optimal behavior by the firm is consistent with this stylized fact, either if demand exhibits positive serial correlation, or if the firm can backlog excess demand.

This paper examines the impact of changes in gasoline price expectations on the market values of used automobiles. An asset model of automobile valuation is used to relate year-to-year changes in market values to changes in the present discounted value of gasoline expenses. Econometric evidence from data covering the years 1972 through 1981 substantially confirms the hypothesis of the model that a gasoline price shock causes relative price changes across automobile types in proportion to the differences in their rates of fuel consumption.

The countercyclical pattern of inventory-sales ratios is a striking feature of inventory behavior. In a model where inventories are productive for sales, both the markup of price over marginal cost and expected changes in marginal cost are key determinants of that ratio. This paper argues that costly variation in factor utilization gives rise to countercyclical markups in production-to-stock manufacturing industries. The markup turns out to be more important than intertemporal substitution in explaining the behavior of inventory-sales ratios.
