‘Adopt a Hypothetical Pup’: A Count Data Approach to the Valuation of Wildlife

The willingness to pay (WTP) for a coyote conservation program is estimated using a novel payment-vehicle, based on how many ‚problem’ coyotes respondents would be willing to sponsor for a year. This hypothetical scenario mimics an increasingly popular type of actual market. Data from a phone survey conducted in Prince Edward Island are analyzed using count data models that consider different processes explaining zero responses and the level of positive responses. This is particularly important in the case of coyotes, often regarded as an economic bad. Estimates of WTP per coyote per year around $18–$22 and annual WTP per contributor of about $46–$57 are obtained.      

Climate Change Taxes and Energy Efficiency in Japan

In 2003 Japan proposed a Climate Change Tax to reduce its CO₂ emissions to the level required by the Kyoto Protocol. If implemented, the tax would be levied on fossil fuel use and the revenue distributed to encourage the purchase of energy efficient equipment. Analysis using the MIT Emissions Prediction and Policy Analysis (EPPA) model shows that this policy is unlikely to bring Japan into compliance with its Kyoto target unless the subsidy encourages improvement in energy intensity well beyond Japan’s recent historical experience. Similar demand-management programs in the US, where there has been extensive experience, have not been nearly as effective as they would need to be to achieve energy efficiency goals of the proposal. The Tax proposal also calls for limits on international emission trading. We find that this limit substantially affects costs of compliance. The welfare loss with full emissions trading is 1/6 that when Japan meets its target though domestic actions only, the carbon price is lower, and there is a smaller loss of energy-intensive exports. Japan can achieve substantial savings from emissions trading even under cases where, for example, the full amount of the Russian allowance is not available in international markets.     

Evolutionary macroeconomics: a research agenda

In this article, the goal is to offer a new research agenda for evolutionary macroeconomics. The article commences with a broad review of the main ideas in the history of thought concerning the determinants of economic growth and an introduction to the evolutionary perspective. This is followed by a selective review of recent evolutionary approaches to macroeconomics. These approaches are found to be somewhat disconnected. It is argued that the ‘micro-meso-macro’ approach to economic evolution is capable of resolving this problem by offering an analytical framework in which macroeconomics can be built upon ‘meso-foundations’, not micro-foundations, as asserted in the mainstream. It is also stressed that the economic system and its components are complex adaptive systems and that this complexity must not be assumed away through the imposition of simplistic assumptions made for analytical convenience. It is explained that complex economic systems are, at base, energetic in character but differ from biological complex systems in the way that they collect, store and apply knowledge. It is argued that a focus upon stocks and flows of energy and knowledge in complex economic systems can yield an appropriate analytical framework for macroeconomics. It is explained how such a framework can be connected with key insights of both Schumpeter and Keynes that have been eliminated in modern macroeconomics. A macroeconomic framework that cannot be operationalized empirically is of limited usefulness so, in the last part of the article, an appropriate methodology for evolutionary macroeconomics is discussed.     

中国养活自己能力的长期预测:技术和政策分析

中国拥有世界五分之一强的人口 ,收入又在迅速增长。因此 ,国际上很自然地会考虑或推测她在今后的几十年是否有能力养活自己。中国的人口预计将从 2 0 0 0年的 1 2 8亿增长到 2 0 2 0年的 1 4 6亿 ,和 2 0 3 0年的 1 4 9亿。与此同时 ,人均收入的增长将导致对家畜和鱼类产品更大的需求 ,因而对饲料的需求也将有很大的增长     

Measurement of Changes in Economic Welfare in India: 1970–2001

This paper provides time series estimates of measures of economic welfare, inequality, decile class specific true cost of living index and poverty measures based on 20 rounds of National Sample Survey data for the period 1970–2001. It has estimated piece-wise Linear Expenditure System (LES) for very poor, moderately poor, non-poor low and non-poor high expenditure groups for rural as well as urban areas. Money metric utility for deciles are derived from the money metric utility function and social welfare index is constructed by aggregating metric utility of the deciles. Using social welfare index as well as real per capita consumption, the paper analyses the changes in economic welfare over the three decades. Using conventional measures, the paper analyses the changes in poverty and inequality during 1970–2001. The paper also provides estimates of the welfare effects of commodity prices.

     

Regulatory Barriers and Entry into a New Competitive Industry

We model the effects of license fees and bureaucratic delay on firm entry into a new competitive industry, whose profitability is initially unknown. A license fee alone reduces the number of first movers and the steady‐state number of firms. The combination of license fee and delay may cause some entrepreneurs to purchase licenses speculatively, only using them to enter production later if profitability is revealed to be sufficiently favourable. Alternatively, some entrepreneurs may wait, possibly buying a license only after profitability is revealed; but it is never found that some entrepreneurs adopt one of these strategies and some the other.     

Compositional data analysis and zeros in micro data

The application of compositional data analysis methods in economics has some attraction. The methodology relies upon the use of 'log-ratios' in the statistical analysis. Such an approach is not possible when the data to be analysed include observations where the observed budget share is zero. We, therefore, consider and extend the methods of compositional data analysis in the situation where the data to be analysed include observations where the observed budget share is zero. The modified compositional data methods are discussed both in statistical terms and through potential economic interpretations of the method. Further, the modified methodology is applied to the 1988-89 Australian Household Expenditure Survey yielding estimates for a system of Engel curves.     

Panel estimates of the earnings gap in Norway: do female immigrants experience a double earnings penalty?

This study explores the possibility that being both a ‘female’ and an ‘immigrant’ will impose an earnings disadvantage on immigrant women in Norway. Well-known techniques are used to decompose the earnings gap between Norwegian men and immigrant women into portions attributable to productivity differentials, portions attributable to a gender effect, and portions attributable to an ethnic effect. The analysis supports the following conclusions: First, there is evidence of a double negative effect on female immigrant earnings. Second, gender effect is more important than ethnic effect. Finally, the discrimination estimates are robust to the alternative methods used in decomposing Norwegian men-immigrant women earnings gap.     

Green marketing strategies: an examination of stakeholders and the opportunities they present

As green marketing strategies become increasingly more important to firms adhering to a triple-bottom line performance evaluation, the present research seeks to better understand the role of “green” as a marketing strategy. Through an integration of the marketing, management, and operations literatures, an investigative framework is generated that identifies the various stakeholders potentially impacted through the environmentally friendly efforts of a firm. Specifically, the inter-connected nature of the core business disciplines of marketing, management (both strategy and human resources), and operations are examined as controllable functions within an organization from which strategies can be enacted to affect a firm’s stakeholders. The prior research in these areas is examined to identify potential research opportunities in marketing while also offering a series of representative research questions that can help guide future research in marketing.
