ASSESSING THE COMPETITION FACED BY OIL PIPELINES

This paper assesses the competition faced by oil pipelines. It also uses a new procedure and new data to test whether oil pipeline markets are competitive or monopolistic, under standard definitions. The key innovation of the paper is a new approach to the definition of the relevant market(s) in which oil pipelines operate. While recognizing that pipeline monopsony also could be a problem under certain conditions, the paper argues that these conditions are unlikely to arise and that if they do, it is unclear whether pipeline owners would be in a position to exploit them. The study offers new evidence to fuel the 80-year-old debate over pipeline rates and regulation.     

Primary Commodity Prices and the Terms of Trade*

This paper provides a survey of a range of issues involved in the analysis of primary commodity prices and the terms of trade. Particular emphasis is placed upon the long-run behaviour of the terms of trade between primary commodities and manufactures and the paper presents some new evidence regarding the long-run behaviour of Australia's terms of trade.     

ARMY RECRUITING IN A CHANGING ENVIRONMENT

Army recruiting is sensitive to fluctuations in labor market conditions. Declines in unemployment over the past several years have led to decreases in the number and quality of enlistments. The Army has several discretionary policy tools that it can use to reduce cyclical variations in recruiting. However, budget constraints and other external requirements often limit the flexibility of these tools. More recently, the recruiting outlook turned favorable for the Army, primarily due to planned reductions in end strength. These reductions imply a 20 to 30 percent drop in total enlistment requirements over the next several years compared with 1989 levels. The danger is that dramatic budget cuts will impair the manpower quality goals of recruiting. Recruiting cuts alone should not be the only means of meeting end-strength reductions to 1995.     

GRAZING ON PUBLIC RANGELANDS: AN EVOLVING PROBLEM OF PROPERTY RIGHTS

Competition for publicly owned natural resources may be intensified when property rights are incomplete. Incomplete delineation of these rights among claimants to the various resource attributes of the public rangelands of the western United States has resulted in high transaction costs for capturing and/or protecting unassigned rights. This paper addresses how changes in the values society places on the public land resources have resulted in changes in the relative positions of various interest groups with respect to resource allocation decisions. The paper concludes by discussing implications of the property right approach for land management policies and grazing fees.     

CONSEQUENCES OF MINIMUM WAGE INDEXING

During the 1980s, the minimum wage fell relative to prices and average wages in the U.S. economy. If the minimum to average wage ratio had been constant at the level maintained through the 1970s, the minimum wage would have been $5.51 in 1993. If the 1993 minimum wage had increased to $5.51, payments to minimum wage workers would have increased by an estimated $20.3 billion, and the number of people earning that wage would have risen from 2.0 million to 14.7 million. Elasticity estimates generated from other studies indicate that employment would have fallen 240,000 (4.4%) among 16–19 year olds and 349,000 (3.0%) among 20–24 year olds. Wage payments to minimum wage workers would have substantially increased, but the effect on family income distribution would have been small. Many minimum wage workers are children living with parents or adults in a family with other earners. Consequently, 75% of minimum wage workers account for less than half of their family's income.     

Forward Discount Bias: Is it Near-Rationality in the Foreign Exchange Market?*

A risk-averse US investor adjusts the shares of a portfolio of short-term nominal domestic and foreign assets to maximize expected utility. The optimal strategy is to respond immediately to all new information which arrives weekly. We develop a model to estimate the cost of optimizing less frequently and find that it is generally very small. For example, if the investor adjusts portfolio shares every three months, an average expected utility loss of 0.16 per cent p.a. is incurred. Hence, slight opportunity costs of frequent optimization may outweigh the benefits. This result may help explain forward discount bias.     

PARTISAN POLITICS, INTEREST RATES AND THE STOCK MARKET: EVIDENCE FROM AMERICAN AND BRITISH RETURNS IN THE TWENTIETH CENTURY

We examine the relationship between government partisanship, interest rates and the mean and volatility of stock prices in the United States and United Kingdom. We suggest that traders in the stock market rationally expect higher (lower) post-electoral interest rates during the incumbency of the left-wing (right-wing) party – Democrats and Labor (Republican and Conservative) – and in election years when they expect the left-wing (right-wing) party to win elections. We hypothesize that expectations of higher (lower) interest rates decrease (increase) the mean and volatility of stock prices during the actual incumbency or even anticipation of a left-wing (right-wing) party holding the office of the chief executive. Results from empirical models estimated on data from U.S. and U.K. markets over most of the twentieth century statistically support our claims.     

Technology Shocks and Job Flows

We consider a version of the Solow growth model where technological progress can be investment specific or investment neutral. The labour market is subject to search frictions, and the existing productive units may fail to adopt the most recent technological advances. Technological progress can lead to the destruction of technologically obsolete jobs and cause unemployment. We calibrate the model to replicate the high persistence that characterizes the dynamics of firms' neutral technology and the frequency of firms' capital adjustment. We find that neutral technological advances increase job destruction and job reallocation and reduce aggregate employment. Investment-specific technological advances reduce job destruction, have mild effects on job creation, and are expansionary. Hence, neutral technological progress prompts Schumpeterian creative destruction, while investment-specific technological progress operates essentially as in the standard neoclassical growth model. Using structural VAR models, we provide support to the key dynamic implications of the model.     

Work is a Four‐Letter Word: The Economics of Work in Historical and Critical Perspective*

The article highlights and explains the neglect of the activity of work in much of the mainstream economics literature. The neglect of work is seen to have denied space for mainstream economists to engage with the full range of possibilities for progress in human well‐being. The article also considers perspectives on work from within heterodox or non‐mainstream economics and argues that these perspectives provide a superior foundation for the theorization of work.     

SCHOOL CHOICE: SUPPORTERS AND OPPONENTS

We examine the attitudes of Ohio homeowners about school choice, which includes open enrollment programs, school vouchers, tuition tax credits, and charter schools. Previous studies examine more limited forms of choice and investigate fewer possible influences. Overall we report at least five new findings and five findings that contradict previous studies. We find the strongest predictors of opposition for school choice are people having graduate degrees and living in high‐performing public school districts. We find people living in blue collar areas and using private schools to be the strongest predictors of support. Males tend to oppose choice and African Americans support it. We find no role for income, the convenience of alternative schools, or the protection of house values in support for school choice. Overall we report at least five new findings and five findings that contradict previous studies. (JEL H44, I22)
