Bush v. Gore and the Effect of New Source Review on Power Plant Emissions

New Source Review (NSR) is a Clean Air Act regulation that requires electric utilities to meet emission standards when making modifications to existing power plants. The regulation increases the cost of replacing worn out parts, and limits the firm’s scope of potential capital investments. Such restrictions may lead to greater retirements and lower utilization, adversely affecting profits. Prior to the 2000 presidential election, investors expected Bush to have a narrower interpretation of NSR than Gore. Therefore, we use changes in stock prices to estimate the effect on profits of differences in NSR policy. Our results indicate that investors expected the average boiler to be $38 million more valuable under the Bush administration. Over the boilers’ lifetimes, the additional utilization will have increased emissions by 19 million tons of sulfur dioxide, 5.9 million tons of nitrogen oxides and 980 million tons of carbon dioxide, relative to natural gas generation.

Fairness and the employment contract: North American regions versus Germany

Substantial evidence shows that North Americans are generallymore accepting of the market than Europeans and attribute marketoutcomes to a larger degree to effort or skill. Thus, NorthAmericans might be more accepting of layoffs and pay cuts thanGermans, and Germans might be more sensitive to the proceduresand conditions under which pay cuts and layoffs occur. The empiricalresults from our quasi-experiment are largely in line with thesehypotheses. The results may help to explain and be explainedby the different labour market institutions in the differentregions.     

Ensuring quality in higher education through student fees1

The article questions the myth of inequality and elitism on the grounds of tuition fees in higher education. It argues that the key to a successful transformation in higher education lies in the ability to provide ‘high quality products,’ driven by independent charges or fees and an equitable loan finance system. Unless these conditions are met, the author predicts an overcrowded university system and falling academic standards.     

A collective,undifferentiated accounting profession: an Australian study

A study of 386 potential and current members of the accounting profession in Australia and South‐East Asia provides evidence of the importance of three attributes – brand/reputation, international recognition of qualifications and career opportunities – in the decision to join a professional accounting body. While these attributes are important, logit regression models indicate that they are not discriminatory in the choice of professional body and suggest a perception of a collective, undifferentiated accounting profession. The marketing of brand/reputation and membership benefits may be a more efficient and effective strategy in attracting members and differentiating the profession if undertaken by a combined or coordinated professional body.     

Unemployment duration and economic incentives—a quasi random-assignment approach

We investigate how economic incentives and spell duration affect hazard rates out of insured unemployment. We take into account that insured unemployment not always ends in employment, but also in disability, training programs, or benefit sanctions. Our empirical basis is Norwegian register data containing variation in economic incentives and spell duration similar to that of random-assignment experiments. We find that the employment and benefit-sanction hazards are negatively affected by the unemployment insurance replacement ratio, but that the effects vary considerably among individuals. There is negative duration dependence in the employment hazard and positive duration dependence in the disability hazard.     

Does Improved Environmental Policy Enhance Economic Growth?

The environmental impacts on an economy is studied over time using endogenous growth theory. Externalities from the environment on production are central in the analysis, and we examine whether an optimal path realizes more rapid economic growth. The paper focuses mainly on developing countries, where production is largely influenced by the environmental quality. The result of the analysis indicates that the economic growth rate may not depend on the internalization of the environmental externality, but rather on the internalization of the human capital externality. The level of economic activity, however, generally seems to depend on the internalization of both externalities.     

Can a Wealthy Economy Gain from an EU Membership? Adjustment Costs and Long Term Welfare Effects of Full Integration—The Norwegian Case

We employ a large scale macroeconometric model to study adjustment problems and long term welfare effects of a Norwegian EU-membership. Accession costs depend significantly on the country's level of GDP, the size of its agricultural sector and tariff and VAT revenues as these elements determine the net membership contribution. Without the transfers, integrating the economy into EU generates a small welfare gain. This result is strongly affected by a long period with under-utilisation of resources. With the net contribution included, we identify a welfare loss. This is especially so if fiscal policy is changed to maintain the public sector budgetary balance.
