Open access harvesting of the Northeast Atlantic minke whale

The purpose of this paper is to analyze open access exploitation of the Northeast Atlantic minke whale. In particular the question whether open access could lead to stock extinction is addressed. A bioeconomic model of the open access fishery is developed and estimated for data from Norwegian whaling. Numerical analysis shows that open access was not likely to have lead to stock extinction for the minke whale.     

GROWTH, INEQUALITY, AND POVERTY: A CAUTIONARY NOTE

Economic growth had less impact on poverty rates in the 1980s than in the 1960s. Could this be explained by Locke Anderson's observation that the higher median income, the greater the amount of growth needed to achieve a percentage point fall in the poverty rate? No, higher poverty rates are due instead to the rise in income inequality. With higher inequality, however, trickle down could be as effective in the 1990s as it was in the late 1960s. More generally, assessments of anti-poverty policy must recognize that inequality is as vital to changes in the poverty rate as growth in mean income.     

Selling Australia as ‘clean and green’*

‘Clean and green’ has been used as a marketing tool by Australian governments to promote agricultural products overseas. But how valid are these claims? Is the ‘clean and green’ image campaign effective? And should government be involved? We conclude that Australia may have had a ‘clean and green’ image in some markets, but in the future, concrete proof of environmental and quality credentials will be required to satisfy increasingly better‐informed and more demanding customers. We argue that governments cannot, and should not, continue to promote Australian products based on an undefined ‘clean and green’ image. Rather, more resources should be directed to the development, promotion and wide adoption of integrated, credible and well‐defined environmental management and quality assurance systems if Australia is to compete effectively in export markets, especially in the longer term.     

Environmental Regulations,Producer Responses,and Secondary Benefits: Carbon Dioxide Reductions Under the Acid Rain Program

This paper derives a production analysis framework for modeling secondary benefits from environmental regulation, i.e. induced changes in yet unregulated pollutants. We emphasize the various ways in which the producers can respond to environmental regulations, and evaluate them in terms of their costs and their generation of secondary benefits. An application on the US electricity sector illustrates our main point: In our case, abatement technologies that reduce regulated emissions while leaving the plants’ unregulated emissions unchanged appear to be among the least costly producer responses to the existing sulfur and nitrogen regulations, but at the expense of limited secondary reductions in carbon dioxide emissions. This finding raises questions about the magnitude of the much debated secondary benefits from future regulations on carbon dioxide emissions, since similar abatement technologies are currently being developed for carbon dioxide. With new environmental issues emerging over time, our findings suggest that regulators should signal the possibilities of new regulations on connected pollutants to producers. Such information may be relevant for producers when choosing current abatement strategies—with minor cost increases to deal with today’s issues, overall compliance costs for near-future environmental problems may be lowered.     

Traditions,Land Rights,and Local Welfare Creation: Studies from Eastern Indonesia

This research focuses on the impacts of traditional systems of land distribution among households, clans, and the government in two of Indonesia’s poorest provinces: East Nusa Tenggara and Maluku. Our main goal is to discuss and propose alternative ways of dividing and governing productive land to meet new needs in the management of agriculture and forestry. We apply a mixed research methodology that includes in-depth discussions with more than 50 key informants and survey interviews with 640 randomly selected respondents. We find that the number of land conflicts is rising, that land privatisation is becoming increasingly relevant, and that communal land ownership tends to lead to land under-utilisation rather than to natural resource overuse and environmental degradation. We argue that economic gains can be made by changing land-use patterns and land user rights. Our policy recommendations include introducing formalised and taxable clan land ownership with specified and registered family user rights.     

R&D incentives in compatible networks

Network externalities describe the phenomenon that a good becomes more valuable to each user the more other consumers use the same or a compatible troduct. Whereas most of the recent literature on network effects has focused on the adoption of products, this paper shows that network externalities can have important feedback effects on the incentives to carry out R&D and develop new products. Even if the products are compatible, network effects can lead to strategic overinvestment or underinvestment. The firms' R&D decisions are compared with the socially optimal ones.     

Price Volatility and Banking in Green Certificate Markets

There is concern that prices in a market for Green Certificates (GCs) primarily based on volatile wind power will fluctuate excessively, leading to corresponding volatility of electricity prices. Applying a rational expectations simulation model of competitive storage and speculation of GCs the paper shows that the introduction of banking of GCs may reduce price volatility considerably and lead to increased social surplus. Banking lowers average prices and is therefore not necessarily to the benefit of “green producers”. Proposed price bounds on GC-prices will reduce the importance of banking and even of the GC system itself.The paper benefited from presentations at Copenhagen University, Stockholm School of Economics and University of Iceland.

A framework for selection of strategy for management of security measures

In this paper, we present and discuss a framework for security risk management, focusing on the selection of a management strategy for decision-making on security measures in particular. The framework provides guidance on the selection of a suitable type of management strategy for various types of decision-making contexts. An Information and Communication Technology case study is used to illustrate the practical implications of the framework.     

Information flows and adaptation in Tanzanian cottage industries

The aim of this research is to identify channels of information flows and their impact on business adaptation and survival. The analysis is set within a theoretical framework of information market failure and information flows. The paper draws on empirical data from a survey comprising approximately 400 small-scale entrepreneurs in dressmaking and woodworking industries at different levels of centrality in four regions in Tanzania. The data reveal that half of the businesses are growing and one-third have increased profitability by significant adaptations last year. Most changes occur in products and design. Customers and the media represent the most important sources of business information, followed by family members and business partners. Independent variables that significantly influence adaptability include customer relations, education, media exposure, social networks, and mobility. Associations are strongly modified by the entrepreneurs’ age and gender and by businesses’ size and location. The paper concludes that cottage industries in Tanzania have a remarkable ability to survive. Garment and woodwork markets are still predominantly local and competition from external businesses is limited. Access to business information and new ideas should be improved, however, to counteract growing competition from the modern sector.
