| Abstract: | Desvousges, Mathews and Train (2015) find that their contingent valuation method (CVM) survey data does not pass the adding up test using a nonparametric estimate of mean willingness-to-pay. Their data suffers from non-monotocity, flat bid curve and fat tails problems, each of which can cause willingness-to-pay estimates to be sensitive to the approach chosen to measure the central tendency. Using additional parametric approaches that are standard in the literature, I find that willingness to pay for the whole is not statistically different from the sum of the parts in two of three additional estimates. In additional robustness checks, all six of the additional tests find that the WTP estimates do not reject the adding up hypothesis. The negative result in Desvousges, Mathews and Train (2015) is not robust to these alternative approaches to willingness-to-pay estimation. |

| Abstract: | We survey Brazilian coffee farmers’ preferences for attributes of voluntary sustainabilitystandards using a choice experiment. We collected original data from 250 coffee farmers wholive in the state of Minas Gerais who were asked to choose from several hypothetical buyingcontracts for eco-certified coffee. Our results suggest that both cash and non-cash paymentsmay motivate farmers to participate in sustainability standard certification schemes that re-quire improved agricultural practices. Preferences for non-cash rewards such as long-termformal contracts or technical assistance, however, appear highly heterogeneous. Results more-over show that the minimum willingness-to-accept for the adoption of composting is twiceas high as the average price premium for certified coffee in the current context, which maypartly explain why most coffee farmers continue to be reluctant to enter the most stringenteco-certification schemes such as the organic standard. |

| Abstract: | Crowding on public transport (PT) is a major issue for commuters around the world. Nevertheless, economists have rarely investigated the causes of crowding discomfort. Furthermore, most evidence on the costs of PT crowding is based on trade-offs between crowding, travel time and money. First, this paper assesses discomfort with PT crowding at various density levels across heterogeneous individuals using a different methodology. Based on a survey of 1000 Paris PT users, the negative relationship of in-vehicle density on reported satisfaction is similar to previous studies investigating PT crowding costs and stable across most individual characteristics. We also find a sensitive increase in crowding costs over users’ income. Second, we investigate the causes of this discomfort effect. We identify three key drivers: (a) dissatisfaction with standing and not being seated; (b) less opportunities to make use of the time during the journey; (c) the physical closeness of other travelers per se. |

| Abstract: | Increasing attention is being paid to the building sector due to its importance in the climate change debate. In recent years, a growing literature on the price premium paid by consumers to access more efficient and sustainable buildings has emerged as a common topic in hedonic model estimations. In this paper, we aim to provide a summary of this literature by conducting a meta-analysis of more than 50 studies from around the world. In this way, based on a random effects models and weighted OLS robust clustering estimations, we offer an average estimation of the price premium accepted by economic agents (in terms of sale prices) in order to enjoy energy efficient and sustainable buildings. This supports the argument that investing in building refurbishment is worthwhile and economically relevant. However, our data seem to show a major publication bias. Correcting for this bias leads us to halve the original estimation (from 8% to 4%). In addition, we analyze the sources of result dispersion by performing a meta-regression using different moderators (type of publication, sample analysis period, econometric method, etc.). We also carry out different statistical tests and use alternative selection criteria in order to check whether our estimations are robust. Finally, we make recommendations for future hedonic studies as well as for upcoming meta-analyses of the green building premium.. |
