Wage and price controls in the equilibrium sequential search model

In this paper, we study the effects of wage and price controls on employment, output, and welfare in a simplified version of the Bénabou (J. Econom. Theory 60 (1993) 140) equilibrium sequential search model with bilateral heterogeneity. We show that a price ceiling increases output but the change in welfare depends on three effects: the reduction in aggregate search costs, the increase in surplus due to increased output, and the transfer of production to the least efficient firm. The model is formally identical to a standard equilibrium search model of the labor market so analogous results hold for the minimum wage.     

A Proposed Arbitration Mechanism to Ensure Free Trade in Livestock Products

Trade negotiations between Canada and the United States are to begin in the near future. For there to be an ongoing free movement of commodities the question of nontariff barriers must be addressed in the negotiations. Livestock commodities are particularly prone to nontariff barriers due to the public health aspects of domestic regulations and the perishability of the products. Potential nontariff barriers in livestock and meat products are identified and the problems of normal negotiation procedures outlined. A proposal for an arbitration mechanism for the settlement of disputes is developed. It's essential elements are pre-approval of changes to regulations, extremely short arbitration periods and decentralized adjudication.
Les négociations de commerce entre le Canada et les États-Unis commenceront bientôt. Pour avoir un mouvement continuel des denrées, la question des barrières nontarifaires doit être adressée dans les négotiations. Les denrées bestiaux sont particulièrement portées aux barrières nontarifaires à cause des aspects de la santé publique dans les régulations domestiques et la nature périssable des produits. On identifie les barrières nontarifaires potentielles en des produits bestiaux et de viande. On indique aussi les problèmes avec les processus de négotiation normale. Une proposition pour un mécanisme d'arbitrage pour la résolution des disputes est developpée. Les elements essentiels de cette proposition sont l'approbation en avance des changements aux régulations, les périodes d'arbitration très courtes et les prononcements de jugements décentralisés.     

Time Series Concepts for Conditional Distributions*

The paper asks the question – as time series analysis moves from consideration of conditional mean values and variances to unconditional distributions, do some of the familiar concepts devised for the first two moments continue to be helpful in the more general area? Most seem to generalize fairly easy, such as the concepts of breaks, seasonality, trends and regime switching. Forecasting is more difficult, as forecasts become distributions, as do forecast errors. Persistence can be defined and also common factors by using the idea of a copula. Aggregation is more difficult but causality and controllability can be defined. The study of the time series of quantiles becomes more relevant.     

The Relation Between Insider-Trading Restrictions and Executive Compensation

In this study I investigate the relation between firm‐level insider‐trading restrictions and executive compensation. Using a trading‐window proxy for the existence of such restrictions, I test predictions that insiders will demand compensation for these restrictions and that firms will need to increase incentives to restricted insiders. I find that firms that restrict insider trading pay a premium in total compensation relative to firms not restricting insider trading, after controlling for economic determinants of pay. Furthermore, these firms use more incentive‐based compensation and their insiders hold larger equity incentives relative to firms that do not restrict insider trading. These results hold after controlling for the endogenous decision to restrict insiders and are consistent with the notion that insider trading plays a role in rewarding and motivating executives.     

Business portfolio restructuring,prior diversification posture and investor reactions

This study examined firm performance in market reaction to two types of business portfolio restructuring announcements: refocusing and repositioning. We predicted that market performance effects for these two types of strategic restructurers would be moderated by prior diversification posture. The theory behind these expectations was built on a general premise that restructuring strategy would be more favorably viewed by the market as performance enhancing when it offered greater potential for organizational transformation. Results showed strong support for our conclusion that prior diversification posture poses a significant contingency factor in restructuring firms' strategic choices. Further, the market tended to respond more favorably with this sample to repositioning restructuring choices. Copyright © 2003 John Wiley & Sons, Ltd.     

Quasi‐rational and ex ante price expectations in commodity supply models: an empirical analysis of the US broiler market

A statistically optimal inference about agents' ex ante price expectations within the US broiler market is derived using futures prices of related commodities along with a quasi‐rational forecasting regression equation. The modelling approach, which builds on a Hamilton‐type framework, includes endogenous production and allows expected cash price to be decomposed into anticipated and unanticipated components. We therefore infer the relative importance of various informational sources in expectation formation. Results show that, in addition to the quasi‐rational forecast, the true supply shock, future prices, and ex post commodity price forecast errors have, at times, been influential in broiler producers' price expectations.

Exploring the future for pensions pillarisation

The pensions pillarisation agenda envisages a reduction in the role of social insurance while simultaneously advocating the parallel expansion of fully funded private sector, occupational and personal retirement contingencies. Widespread perception of looming state failure in the field of pensions delivery highlights the inherent limitations of current pension delivery arrangements. However, moves to de-emphasise the provision afforded by, predominantly, monopillar state-mandated pension systems by expanding private privision represent short-term palliative responses to deep rooted structural and demographic problems. Multipillar systems appear no more capable of guaranteeing system funding in the face of demographic ageing and structural unemployment than existing monopillar systems. Moreover, a diminished role for social insurance will leave the low paid and unemployed significantly more vulnerable in old age. Consequently, this paper argues for a pension reform agenda which, in terms of levels of income substitution, will secure an adequate social insurance element into the future.
