Slave prices,the African slave trade,and productivity in the Caribbean, 1674–18071

We draw wide‐ranging implications about slave productivity change by making use of newly collected data on the prices paid for nearly 230,000 slaves as they arrived in the Americas from Africa between 1674 and 1807. Prices for the product that most slaves were destined to produce‐sugar‐are also available. Together the comprehensive series allow us to derive annual measures of average slave productivity and to compare productivity trends across different sectors of the Caribbean. Average productivity rose throughout the Caribbean, and the pattern of average productivity change across regions was similar, indicating an open slave market. These averages mask sharp differences in the growth of demand for slaves among regions, as reflected by their slave populations. Between 1700 and 1790 the increase in demand ranged from 90 per cent in Barbados to 600 per cent in Jamaica and Cuba; while total factor productivity overall may have doubled. The slave trade accommodated the rising demand. It also served to offset population attrition among the slaves.     

Holiday Trading in Futures Markets

In this paper, we find significantly higher preholiday returns in futures contracts compared to nonholiday returns. The findings are consistent with the inventory adjustment hypothesis, since higher preholiday returns associated with lower trading volume are most pronounced for exchange-closed holidays. There is evidence of positive postholiday returns associated with higher trading volume for exchange-open holidays. This is consistent with positive holiday sentiments. The holiday effect is uniquely independent: The magnitude of excess holiday returns is the largest among all seasonal variations.     

Planning for Peace in Contested Space

This article explores the debate about contested space in urban policy and planning. Beginning with a review of key concepts and theories, it proceeds to identify models for understanding such spaces and for effective public intervention. It takes a case study of Belfast, on which there is substantial literature and data, to explore whether the recent history of this city can contribute to the debate about the role of urban planning and policy in contested space. Finally, it suggests that the Belfast experience indicates the need for a broader framework of intervention than is possible within a purely planning paradigm.     

Imperfect Competition and Corporate Governance

This paper studies the objective function of the firm in imperfectly competitive industries. If those involved in decisions are also consumers the usual monopoly distortion is reduced. In oligopolistic industries, this may give the firm a strategic advantage and hence, in the right circumstances, will increase profit. If the firm cannot commit not to change its constitution, we find a Coase‐like result where all market power is lost in the limit. This enables us to endogenise the objective function of the firm. Finally we present a more abstract model of governance in the presence of market distortions.     

RESEARCH PRODUCTIVITY OF AUSTRALIAN ACADEMIC ECONOMISTS: HUMAN‐CAPITAL AND FIXED EFFECTS*

This study investigates why some economics departments in Australian universities are more research productive than others. The hypothesis is simple: research productivity depends upon the human capital of department members and the department‐specific conditions under which they work. A Tobit model is used to estimate the magnitude of the two effects. Both are found to be important. Our results help explain why a small number of departments consistently outperform the others in studies that rank Australian economics departments according to research output.
