Evidence of Racial Discrimination in Different Dimensions of Owner-Occupied Housing Search

This paper examines the incidence and extent of racial discrimination in various dimensions of owner-occupied housing search. Audit data for sales units (1980-90) from the Fair Housing Center of metropolitan Detroit is used in an ordered probit framework. Agents' own prejudices and the prejudices of their customers are shown to be significant in explaining discrimination. Results also indicate that white home seekers are steered toward more white and affluent neighborhoods.     

AIRLINE DEREGULATION AND THE PROBABILITY OF AIR CARRIER INSOLVENCY

This study investigates the effects of deregulation from the perspective of airline lenders. Airline-specific, pre- and post-deregulation insolvency probabilities are used to assess the effects on creditors. The results suggest that the financial condition of several airlines has significantly deteriorated as a by-product of deregulation, although most have been unaffected.     

Aggregate Fluctuations with National and International Returns to Scale*

Cyclical movements in aggregate output, factor inputs, and productivity are all positively correlated across countries. This article proposes a model in which positive cross‐country correlations of these variables result from increasing returns to the world‐wide variety of intermediate goods even if technology shocks are purely country‐specific. The model also accounts for the observed positive relationship between bilateral trade volume and international comovements. Positive comovements can also arise with constant returns to variety, but only if technology shocks are themselves strongly correlated. The combination of constant returns and common shocks, however, tends to generate procyclical fluctuations of the trade balance.     

Multivariate GARCH hedge ratios and hedging effectiveness in Australian futures markets

We use the All Ordinaries Index and the corresponding Share Price Index futures contract written against the All Ordinaries Index to estimate optimal hedge ratios, adopting several specifications: an ordinary least squares‐based model, a vector autoregression, a vector error‐correction model and a diagonal‐vec multivariate generalized autoregressive conditional heteroscedasticity model. Hedging effectiveness is measured using a risk‐return comparison and a utility maximization method. We find that time‐varying generalized autoregressive conditional heteroscedasticity hedge ratios perform better than constant hedge ratios in terms of minimizing risks, but when return effects are also considered, the utility‐based measure prefers the ordinary least squares method in the in‐sample hedge, whilst both approaches favour the conditional time‐varying multivariate generalized autoregressive conditional heteroscedasticity hedge ratio estimates in out‐of‐sample analyses.     

Merger statistics and merger policy

It is widely believed that the 1950 amendment of Section 7 of the Clayton Antitrust Act has diverted merger activity away from horizontal and into conglomerate forms. Examination of the Federal Trade Commission Large Merger Series replicates existing substantiation of this belief, but only up until 1968. Further examination of the data shows a perceptible weakening of the horizontal-merger deterrent in the following eight years. One possible explanation is that all the attention devoted to the “conglomerate problem” after 1968 implied that horizontal mergers were neither as bad nor as illegal as existing case law had made them.     

A decision model for regional industrial recruitment and development

Although the practice of industrial recruitment is widespread among regions, its objectives and constraints are neither well established nor carefully evaluated in determining the most desirable industries. As a result, many regions frequently resort to a blind scramble for new industries. This paper suggests a decision model for a regional economy to determine the priority in industrial recruitment. The problem is formulated in terms of a mathematical programming model in which the objectives and constraints are explicitly stated. Regional input-output, table provides additional constraints in the model. The input-output table is also used in testing the economic feasibility of optimal solutions.     

The British Navy Rules: Monitoring and Incompatible Incentives in the Age of Fighting Sail

The British Navy during the age of sail was systematically successful against its opponents, most notably the French. This paper documents this success, shows that it cannot be explained by superior ships, training, or other naval capital, and puts forth the hypothesis that the British Navy governance structure provided better incentives to fight than those of their opponents. The hypothesis is tested by examining the structure of the rules and then contrasting them with the rules governing privateers, the army, and the navy over time. The paper concludes with a discussion of why the French did not copy the British strategy.
