This paper employs ordered probit, partial adjustment, and vector error correction models to characterize price adjustments in the Philippine retail gasoline market since its deregulation. It finds that pricing decisions of oil firms depend significantly on eight weeks of previous changes in...

Prospective payment systems are currently used in many OECD countries, where hospitals are paid a fixed price for each patient treated. We develop a theoretical model to analyse the properties of the optimal fixed prices to be paid to hospitals when no lump-sum transfers are allowed and when the...

We derive a measure of firm speed of price adjustment that is directly inversely related to market power and compare this to the measure derived by Martin (1993). However, both measures are incorrect when firms have price conjectural variations. This is because Taylor expansions of the demand...

This paper investigates the properties of the Damodaran (Journal of Finance, 1993) estimator of price adjustment. It is concluded that strong bias and low precision of the Damodaran estimator renders it useless for empirical work, even when the available sample size is very large. As an...

We analyze daily mortgage rates posted by online lenders at the price comparison site, Microsurf. While cost shocks occurred almost daily in our sample, quoted mortgage rates are surprisingly rigid: Only 16 percent of the posted rates represent changes. However, firms that adjusted rates in...
