FELLOWS ADDRESS California Dreaming: The Economics of Renewable Energy

California was the first jurisdiction to mandate a reduction in greenhouse gas (GHG) emissions by 80% below 1990 levels by 2050. This target was subsequently endorsed by the G8 in 2009 and the European Commission in 2014, and is the guiding principle of the 2015 Paris Agreement. To achieve these targets will require near elimination of fossil fuels and/or a technological breakthrough that might be considered a black swan event. Eschewing nuclear power, countries are relying on renewable energy sources to meet future energy needs. In this paper, I examine the prospects of reducing GHG emissions by 80% by first summarizing extant global energy sources and production, trends, and projections of energy demand, and the potential mix of future energy sources. I consider the role of conservation and then focus on the electricity sector to determine how wind and biomass could contribute to the 80% target. I conclude that these ambitious targets cannot be attained without nuclear power.     

Rice market integration in the Mekong River Delta1

In the last decades Vietnam has become a major supplier in the world's rice market. This position is the result of the policy reforms that have been implemented in the agricultural sector. This paper assesses the impact of the liberalization policies and focuses on the spatial price differences in the domestic rice market. The results show that price patterns correlate strongly in the Mekong River Delta. Even prices in other regions are integrated with price patterns in the South. Interestingly, private traders in the Mekong Delta are only indirectly responsible for the latter result. They satisfy local demand and deal with state‐owned enterprises (SOEs). In the framework of the national food security policy, the state‐owned food companies ‘subsidize’ transactions between the South and the North. Moreover, the state‐owned food companies still dominate export transactions. The latter issues constitute two major queries for policy makers involved in the liberalization of the rice market, as further policy measures should not jeopardize the interests of domestic rice consumers.     

Segments of sustainable food consumers: a literature review

Sustainable food consumption is an important aspect of sustainable development. When adopting a sustainable food lifestyle, consumers are confronted with complex choices. Today's food consumption is too complex to be explained by socio‐demographic factors exclusively. A broader perspective is needed. In order to explain behaviour across different consumer segments better, relatively homogenous segments of food consumers were identified by segmenting food consumers based on a wide range of variables. The current study aims to provide an overview of published studies that have segmented consumers with regard to sustainable food consumption. The literature review has been conducted by searching SciVerse Scopus for all relevant articles available until November 2010. The main criterion for including a specific study was the inclusion of empirical analyses of primary data, resulting in consumer segments with regard to sustainable food consumption. Sixteen articles were incorporated in the final analysis. First, the variables used for segmentation and profiling in the included articles have been categorized into three levels of abstraction: personality characteristics, food‐related lifestyles and behaviour. The three levels of abstraction proved to be helpful in categorizing the segmentation studies. The findings indicate that variables on all three levels were efficient in differentiating consumer segments regarding sustainability. In addition, the importance of price and health differed across the segments, although these variables are only indirectly related to sustainability. Second, the three most frequently identified consumer segments with regard to sustainable food consumption were: ‘greens’, ‘potential greens’ and ‘non‐greens’. These segments differed from one another on all three levels of abstraction. This implies that future segmentation studies should include variables on all levels of abstraction to get a complete picture of existing sustainable consumer segments. Marketers should be aware that targeting specific segments based on socio‐demographic variables exclusively is not sufficient. Personality characteristics, lifestyle and behaviour are all important to take into consideration. Attempts at stimulating sustainable consumption might be most effective when differences across consumer segments are taken into account. Future research is needed to explore the characteristics of different sustainable food consumer segments with respect to their potential contributions in promoting sustainable development.     

Wege zur Kontinenz

Preference Uncertainty in Non-Market Valuation: A Fuzzy Approach

In this article, we consider uncertain preferences for non-market goods, but we move away from a probabilistic representation of uncertainty and propose the use of fuzzy contingent valuation. We assume that a decision maker never fully knows her own utility function and we treat utility as a fuzzy number. The methodology is illustrated using data on forest valuation in Sweden. Fuzzy contingent valuation provides estimates of resource value in the form of a fuzzy number and includes estimates obtained using a standard probabilistic approach.     

Supply Restricted Telecommunications Markets: The Effect of Technical Efficiency on Waiting Times

The paper is concerned with supply constraints in the provision of telecommunications services. As a measure of supply constraint we use the average waiting time for telephone connections. Duration models are employed to analyze a panel data set for 28 countries. In addition to economic variables, we consider the role of technical efficiency in causing supply constraints. Stochastic frontiers are used to determine the technical efficiency with which countries use labor and capital inputs to connect customers. When technical efficiency is included in duration models for waiting times until connection, we find that it is the major determinant.
