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 non-zero price conjectural variations and treat competing price levels as exogenous. This is because Taylor series expansions of the demand function implicitly assume that firms inf...

An optimising model of price adjustment with missing information is developed where firms choose the speed of price adjustment to minimise the expected loss in disequilibrium. The loss is due to lost profits and the expected cost of failing to coordinate price changes with competitors. Assuming that a higher speed of price adjustment decreases the former and increases the latter, it is shown th...

The standard quadratic price adjustment cost function makes no allowance for firm size or for scale economies. Incorporating quadratic price adjustment costs into the profit function, a firm’s speed of price adjustment is both shown to be a positive/negative function of its size when firms have scale economies/diseconomies with regard to these costs and to be a negative function of market power...

In this research, overreaction and underreaction have been studied by assessing profitability and excess returns of investment strategies and evaluating price adjustment speed in short and long terms. The results showed that the momentum investment strategies had higher annual returns in comparison to contrarian strategies in all short and long periods which led to confirmation of underreaction...

crude oil price and the u.s. effective exchange rate are two main economic variables that have had real effects on world welfare situation. the aim of this paper is to test whether there is a stable long-run relationship between oil prices and the u.s. dollar, expressed in real term. to this end, we perform co-integration and causality tests between the two variables, using quarterly data from ...

in this paper, nonlinear adjustments and price transmission mechanism between the two levels of wholesale and retail for the egg market has been examined under the threshold vector error correction model (tvecm) framework using hansen and seo (2002)’s two-regimes). the unit root test showed that both wholesale and retail egg price series were integrated of order one . the johansen co-integratio...

In Recent Decades, The Financial Sphere has entered a New Era of Contempt for Some of the Assumptions of Modern Economics and Finance. One of These Assumptions is the Rationale of the Investors, which has been Seriously Challenged and Is Now Being Strengthened by the Fact That Prices are Determined more by Attitudes and Psychological Factors than for Fundamental Variables and Therefore the Stud...

A model of industry speed of price adjustment is derived from firm pricing behaviours. The model is applied to quarterly two-digit Australian manufacturing data for the period 1985:3 to 2002:3. Initially, the industry speed of price adjustment is treated as a function of structural cross-section variables. The results suggest that the industry speed of price adjustment is positively related to ...
