Authors:Cerroni S; Watson V, Kalentakis D, et al. Pages: 3 - 27 Abstract: This paper tests if second-price Vickrey auction (SPVA) and discrete choice experiment (DCE) are isomorphic, and whether lack of isomorphism is due to value elicitation, value-formation or both. We conduct an artefactual field experiment that combines induced-value (IV) and home-grown (HG) procedures using SPVA and DCE. Induced-value preferences are elicited for tokens and HG preferences for multi-attribute lasagnes. Attributes are healthiness and environmental sustainability. Our results suggest that HG preferences differ across elicitation methods. This discrepancy is due to value-elicitation and value-formation. DCE is the most demand revealing approach and provides the highest premiums for healthy and environmentally sustainable lasagnes.

Authors:Chavas J; Di Falco S, Adinolfi F, et al. Pages: 29 - 51 Abstract: This paper examines the effects of weather on the distribution of agricultural yields. Using data on wheat and corn yields from seven Italian provinces over the period 1900–2014, a quantile autoregression model is estimated to analyse the dynamic evolution of yield distributions. We find that weather effects are asymmetric, with much larger impacts on the lower tail of the yield distribution than the upper tail. The analysis also shows slow dynamic adjustments. This indicates that adverse weather has significant and persistent effects on agricultural productivity. PubDate: Wed, 11 Jul 2018 00:00:00 GMT DOI: 10.1093/erae/jby019 Issue No:Vol. 46, No. 1 (2018)
Authors:Wuepper D; Wree P, Ardali G. Pages: 53 - 78 Abstract: We use a choice experiment to investigate attitude heterogeneity regarding genetically modified food and how it is affected by the provision of balanced information. For the analysis, we use a generalised multinomial and a latent class logit. The consumers who are more accepting of genetic modifications are younger, less educated and less concerned about their nutrition. The average effect of our provided information is negligible. However, the initially less opposed become slightly more opposed. Our results thus do not support the view that a lack of information drives consumer attitudes. Instead, attitudes seem to mostly reflect fundamental preferences. We discuss implications for research and policy.

Authors:Stack M; Ackrill R, Bliss M. Pages: 79 - 108 Abstract: Past colonialism has shaped current policies and patterns relating to sugar trade. To examine the effects of historical colonial linkages on sugar trade, the gravity model is estimated for a panel of raw sugar imports into 25 OECD countries from the rest of the world over the 1961–2016 period. Colonial linkages in a North–South direction increase sugar trade, but colonial linkages in a North–North direction decrease it. Several distinct North–South colonial channels are identified. Sugar trade is enhanced by the major empire shipping routes, rail infrastructure, cultural proximity and preferential market access.

Authors:Ssebunya B; Morawetz U, Schader C, et al. Pages: 109 - 132 Abstract: Discrepancies in certification effects on smallholder incomes have been found in scientific literature. Unobserved farmer-group heterogeneity is a likely reason. For the long-standing Robusta coffee farmer-groups in Uganda, we find no significant effect of certification on net-farm income. But, we find 20 percentage point differences in net-farm income between certified and non-certified farmers explained by membership duration. In contrast, the recently founded certified Arabica coffee farmer-groups have positive net-farm income effects of 151 per cent, partly explained by a higher degree of vertical integration. With or without certification, long-standing group membership is found to have positive income effects. PubDate: Thu, 19 Jul 2018 00:00:00 GMT DOI: 10.1093/erae/jby022 Issue No:Vol. 46, No. 1 (2018)
Authors:Sandorf E; Campbell D. Pages: 133 - 162 Abstract: Accumulating evidence suggests that respondents in stated choice experiments use simplifying strategies. Such behaviour is a deviation from random utility theory and can lead to wrong inferences regarding preferences. This is a first attempt to systematically explore satisficing in stated choice experiments. We consider 944 satisficing rules and allow respondents to revise the rules adopted throughout the choice sequence. Only a minority of respondents used the same satisficing rule across the entire sequence. Allowing for updating reveals that the use of the heuristic changes over the choice sequence. Considering satisficing behaviour leads to improved model fits and different marginal willingness-to-pay estimates.
