The demand for paper and paperboard: econometric models for the European Union

Cost minimization theory suggests national demand equations for paper and paperboard in which demand is a negative function of the price of paper and paperboard, and a positive function of gross national product. A dynamic version of this model was estimated with data from European Union countries, for newsprint, printing and writing paper, and other paper and paperboard. Country-by-country equations proved unstable. Pooling the data across countries, with dummy variables to account for fixed country effects, led to well defined short-term and long-term elasticities with respect to price and gross national product. The hypothesis that income and price elasticities were the same across the European Union countries could not be rejected at the 1% significance level, for the three product groups. From 1969 to 1995, most of the growth in demand had been due to the growth in national product, while price increases had only a small negative effect.     

Qualitative valuation of environmental criteria through a group consensus based on stochastic dominance

This paper introduces a qualitative valuation method to elicit stakeholders' intensities of preferences for a complex environmental issue and multiple social groups. Environmental valuation studies have shown that in any complex environment with a diversity of environmental services, stakeholders have difficulties using a monetary valuation to make trade-offs between different environmental services. Stated preference methods such as the Contingent Valuation Method (CVM) have been criticised for their individualistic format and assumptions of commensurability between environmental criteria. To alleviate both of these criticisms, we propose a qualitative valuation method. The method contains a discursive step to allow stakeholders to discuss and construct a list of environmental criteria and alternative plans. The list of criteria and plans is subsequently used by a group of experts to formulate an Impact Matrix (IM), which is to be used in the succeeding individualistic steps of the methodology. The first individualistic step consists of asking the stakeholders to rank Alternative Impacts (AIs) in the IM for each single criterion. The stakeholders are then asked to express intensities of their preferences through pairwise comparisons between the AIs of the constructed rank order on each single criterion. These intensities are expressed on a qualitative scale. Subsequently, to provide social intensities of preferences, a social preference (social rank order) is first determined for each single criterion. We propose to use the median value among the intensities of preferences as the social intensity of preference by assuming interpersonal comparability and taking into account stochastic monotonocity. This is a pre-processing step, which allows us to reach social intensities of preferences in the Lar rangeland (Iran), where several social groups have conflicting interests on rangeland services, leading to conflicting preferences on environmental criteria.     

Discount rates and credit markets: Theory and evidence from rural india

Three models of credit markets - (1) the permanent income model, (2) upward sloping credit supply to individual borrowers, and (3) constrained credit due to imperfect enforcement - are tested using credit market data and an experimental study of individuals' discount rates in south India. The permanent income model is rejected by both the discount rate and the credit market data. The discount rate data are consistent with either of the other two models, while the credit market data are consistent with a combination of these two models. Other explanations are found to be insufficient to explain the results of this study.     

Value of agricultural non-point source pollution measurement technology: assessment from a policy perspective

The development of accurate non-point source pollution assessment technologies allows the implementation of more efficient policies than can be undertaken in their absence. This study estimates the value of accurate measurement technology by estimating the gains from implementing a more efficient policy, one that targets agricultural non-point source emission reductions at the field scale but requires accurate field scale measurement technology, relative to a practice-based policy that can be implemented in the absence of such technology. For the environmental benefit of carbon sequestration, large cost savings are found due to improved targeting of conservation tillage subsidies for the state of Iowa. The ability of the government to cost discriminate is found to have little impact on the value of accurate measurement technology.     

Perception of marital roles in purchase decision processes: A cross-cultural study

Following the approach of the classic 1974 marital-role influence study of Davis and Rigaux, the present study focuses on differences in decision making (i.e., joint, husband dominated, wife dominated) across 24 product categories as a function of two key factors. These factors are stage of the decision process (i.e., problem recognition, information search, and the final decision) and culture (People’s Republic of China and the United States). The Jacobson Marital-Role Egalitarianism Scale is included to further assess individual differences in husband and wife traditionality-modernism. The major findings are that emphasis on joint, husband-dominated, and wife-dominated decisions vary by stage and by stage-culture interaction.
