An Empirical Investigation of the Arbitrage Pricing Theory

Empirical tests are reported for Ross' [48] arbitrage theory of asset pricing. Using data for individual equities during the 1962–72 period, at least three and probably four priced factors are found in the generating process of returns. The theory is supported in that estimated expected returns depend on estimated factor loadings, and variables such as the own standard deviation, though highly correlated (simply) with estimated expected returns, do not add any further explanatory power to that of the factor loadings.     

POLITICAL AFFILIATION AND PERCEPTIONS OF TRADE: EXAMINING SURVEY DATA FROM THE STATE OF GEORGIA

We examine the influences of political party affiliation and self-identification as politically conservative, centrist, or liberal on individuals' trade preferences. Majority support for trade is reported for all political classifications, with Republicans found to be 13.7%–15.1% more likely than Democrats and independents to support trade. Similarly, conservatives are 14.8%–21% more likely to support trade than are centrists and liberals; however, distinctions exist between "very conservative" and "somewhat conservative" cohorts.

Labor Law,Economics, and Industrial Democracy: A Reconciliation.

This article analyzes the competing economic and industrial democracy/ voice views of unionism. It points out that the economic arguments vis-àvis unionism and the costs of union rent seeking depend on competitive markets. If markets vary in their competitive characteristics, however, and employers also have an incentive to rent-seek, then decentralized, NLRA-type unionism with minimal government interference in establishing bargaining outcomes may serve to restore competitive wages. The article concludes by evaluating some proposals to amend the NLRA in the context of this “symmetry of motives” framework.     

Was It Real? The Exchange Rate-Interest Differential Relation over the Modern Floating-Rate Period

In this paper, we explore the relationship between real exchange rates and real interest rate differentials in the United States, Germany, Japan, and the United Kingdom. Contrary to theories based on the joint hypothesis that domestic prices are sticky and monetary disturbances are predominant, we find little evidence of a stable relationship between real interest rates and real exchange rates. We consider both in-sample and out-of-sample tests. One hypothesis that is consistent with our findings is that real disturbances (such as productivity shocks) may be a major source of exchange rate volatility.     

Aggregative Public Good Games

We exploit the aggregative structure of the public good model to provide a simple analysis of the voluntary contribution game. In contrast to the best response function approach, ours avoids the proliferation of dimensions as the number of players is increased, and can readily analyze games involving many heterogeneous players. We demonstrate the approach at work on the standard pure public good model and show how it can analyze extensions of the basic model.     

Collective Labour Supply: Heterogeneity and Non-Participation

We present identification and estimation results for the "collective" model of labour supply in which there are discrete choices, censoring of hours, and non-participation in employment. We derive the collective restrictions on labour supply functions and contrast them with restrictions implied by the usual "unitary" framework. Using the large changes in the wage structure between men and women in the U.K. over the last two decades, we estimate a collective labour supply model for married couples without children. The estimates of the sharing rule show that male wages and employment have a strong influence on bargaining power within couples.     

The Dynamic Effects of the US Productivity Boom on Australia*

How has the USA's ‘new economy’ productivity boom affected Australia? We consider this question using a dynamic multisector growth model of the Australian and US economies. We find that productivity growth in the US durables sector generates small but important gains to Australia. We find that the transmission of growth is generated through increased export demand for agriculture. Consequently, the USA's productivity growth tends to favour Australia's traditional export sectors. Likewise, it increases the relative demand for less skilled labour in Australia and reduces the demand for more skilled labour and higher education.     

Price Discovery in Illiquid Markets: Do Financial Asset Prices Rise Faster Than They Fall?

We study price discovery in municipal bonds, an important OTC market. As in markets for consumer goods, prices “rise faster than they fall.” Round‐trip profits to dealers on retail trades increase in rising markets but do not decrease in falling markets. Further, effective half‐spreads increase or decrease more when movements in fundamentals favor dealers. Yield spreads relative to Treasuries also adjust with asymmetric speed in rising and falling markets. Finally, intraday price dispersion is asymmetric in rising and falling markets, as consumer search theory would predict.
