DO PRICES TRANSMIT RATIONALLY EXPECTED INFORMATION?

A simple model with asymmetric information, in which inventory holders or traders submit demand curves to an auctioneer, has a unique partially revealing equilibrium. We wonder whether the agents can plausibly coordinate on this equilibrium through “eductive” reasoning relying on common knowledge. The analysis stresses the role of two effects, sensitivity and amplification, whose product should be small enough. The property is obtained whenever the equilibrium excess demand is steep enough, i.e., when the search for information does not distort demand too much. Neither the influence of the number of informed agents nor that of noise trading are monotonic. Real‐time learning has strikingly different features. (JEL: D82, D84)     

MEASURING FACTORY FOCUS: AN EMPIRICAL STUDY

Focus in the manufacturing plant is generally deemed to be an important element of success in manufacturing strategy. Yet, little work has been completed in the measurement of plant focus and a dearth of empirical evidence exists to support the broad popularity of this concept. This paper presents a plant focus measurement approach and reports the results of a field study that uses a site visit research design to apply the focus measure to a multi-industry sample of manufacturing plants. Regression analysis is used to study the relationships between the plant focus variable and the environmental variables of plant size, number of product lines, plant age, number of processes, and type of processes. Although highly intuitive, these relationships have undergone very little empirical study in the literature. Our study provides evidence of a strong logarithmic relationship between our plant focus measure and the number of product lines. Support is also demonstrated in that our measure of plant focus is linked to the number and type of manufacturing processes. However, the variables of plant age and plant size do not appear related to the plant focus measure. The literature-based multicriteria focus measure can be used by managers and researchers as an objective, formal, and generalizable approach for assessing plant focus, for identifying areas in the plant that detract from focus, and for tracking focus improvement efforts over time.
