We investigate the dynamic portfolio problem of a market-maker for a derivative security whose preferences exhibit uncertainty aversion (Knightian uncertainty). The Choquet-expected utility implied by such preference is used to capture the feature that the trader is uncertain about which model...

We investigate the effect of pro-active comparable worth legislation, covering both the public and private sectors, on wages, employment and the gender gap. Our focus is the pay equity initiative adopted by the Canadian province of Ontario in the early 1990s. Our preliminary finding is that the...

We propose a structural model of investment which is based on the aggregation of (S,s) investment projects within firms. This encompasses the findings that whilst firm level investment is smooth, plant level investment is lumpy and frequently zero. We undertake stochastic aggregation and derive...

The paper proposes a method for construction, estimation, and testing the Rational Beliefs (RB) models. RB models, due to Kurz, 1994, allow agents' beliefs to differ from the Rational Expectations (RE), but require that beliefs cannot be contradicted by past data. By implication, RB and RE must...

This paper investigates the importance of financial institutions, particularly universal banks, in the pricing of risk in securities markets. Recent research on modern economies, finds that three factors explain the cross-section of average stock returns: (i) a stock's sensitivity to market-wide...

We examine the asymptotic and finite-sample properties of tests for equal forecast accuracy and encompassing applied to 1-step ahead forecasts from nested parametric models. We first derive the asymptotic distributions of two standard tests and one new test of encompassing. Tables of...

The aim of this paper is to investigate the relationship between heterogeneity at the firm level and the aggregate behavior of the industry as a whole. Empirical evidence on firm behavior documents the existence of widespread heterogeneity among firms in any industry, both cross- sectionally and...

The logic of the linkage principle of Milgrom and Weber (1982) extends to price discrimination. A non-linear pricing monopolist who sells to a single buyer always prefers to commit to publicly reveal information affiliated to the valuation of the buyer.

This paper explores the effect of organizational structure - in terms of the allocation of authority - on the rate of innovation in multi-unit organizations such as retail chains and multi-plant manufacturers. A computational model is developed in which store managers continually search for...

In the course of the analysis of time series of counts the need to test for the presence of a dependence structure arises regularly. Suitable tests for this purpose are analysed in this paper. Their size and power properties are evaluated under various alternatives among which the...
