| While meta-analysis is typically used to identify value estimates for benefit transfer, applications also provide insights into the potential influence of design, study and methodological factors on results of non-market valuation experiments. In this paper, a metaanalysis of sixteen separate choice modelling studies in Australia with 130 individual value estimates relating to river health are reported. The studies involved different measures and scales of river health, so consistency was generated by transforming implicit prices from each study into a common standard of WTP per kilometer of river in good health. Tobit models have been used to identify the relationships between the dependent variable (WTP/km) and a number of variables. The results... |

| As a contribution to valuing the outputs of multifunctional agriculture, we report three new meta analyses estimating value functions for agricultural conservation program impacts on water quality, wetlands, and upland habitat and open space. As is often the case in valuation, where methods have yet to be standardized, the data sets are relatively small and noisy. With a clear objective of benefits transfer, we seek robust parameter estimates for key RHS variables, even at the cost of some loss of goodness of fit. We present our estimated full equations, and benefits transfer values calculated from equations estimated after backward elimination of insignificant variables, and offer a rationale for this approach to benefits transfer. |

| By conducting a meta-analysis using 50 observations collected from 15 primary studies, we systematically analyze heterogeneities in consumer preferences for U.S. beef products and the results have valuable implications both from a policy perspective as well as from a methodological perspective. The main findings include that consumers in European and Asian countries are willing to pay less for U.S. beef products than those in North American countries and that the BSE incidence in the U.S. substantially damaged consumer preferences for U.S. beef products outside the U.S. but not in the U.S. The results with respect to methodological heterogeneities also indicate that choice experiments yield higher WTP values and that the sample size is negatively... |
