| The past few years have seen a highly charged debate about whether contingent valuation (CV) surveys can provide valid economic measures of people's values for environmental resources. In an effort to appraise the validity of CV measures of economic value, a distinguished panel of social scientists, chaired by two Nobel laureates, was established by NOAA, to critically evaluate the validity of CV measures of nonuse value. The Panel provided an extensive set of guidelines for CV survey construction, administration, and analysis, and distinguished a subset of items from their guidelines for special emphasis and described them as burden of proof requirements. Of particular interest was the Panel's requirement that CV surveys demonstrate "responsiveness to the... |

| Among others who point to environmental variability and managerial uncertainty as causes of fishery collapse, Roughgarden and Smith (1996) argue that three sources of uncertainty are important for fisheries management: variability in fish dynamics, inaccurate stock size estimates, and inaccurate implementation of harvest quotas. We develop a bioeconomic model with these three sources of uncertainty, and solve for optimal escapement based on measurements of fish stock in a discrete-time model. Among other results we find: (1) when uncertainties are high, we generally reject the constant-escapement rule advocated in much of the existing literature, (2) inaccurate stock estimation affects policy in a fundamentally different way than the other sources of... |

| We link farmland values to climatic, soil, and socioeconomic variables for counties east of the 100th meridian, the historic boundary of agriculture not primarily dependent on irrigation. Degree days, a non-linear transformation of the climatic variables suggested by agronomic experiments as more relevant to crop yield gives an improved fit and increased robustness. Estimated coefficients are consistent with the experimental results. The model is employed to estimate the potential impacts on farmland values for a range of recent warming scenarios. The predictions are very robust and more than 75% of the counties in our sample show a statistically significant effect, ranging from moderate gains to large losses, with losses in the aggregate that can become... |
