| Título: | Do roads lead to grassland degradation or restoration? A case study in Inner Mongolia, China |

| Resumen: | We use satellite remote sensing data of grassland cover in Inner Mongolia, China to test whether the existence of and the size of roads in 1995 is associated with the nature of the grassland in 2000 and/or if it affects the rate of change of the grassland between 1995 and 2000. The regression results show that the impact of roads on grassland cover depends on the nature of the resource. When the grassland is composed of relatively high quality grassland, roads lead to degradation, whereas when grassland resources are sparse, access to a road results in the restoration of the resource. |

| Título: | Mapping poverty in rural China: how much does the environment matter? |

| Resumen: | A recently developed small area estimation technique is used to geographically derive detailed estimates of consumption-based poverty and inequality in rural Shaanxi, China. These estimates may be helpful for targeting since there is wide variability in poverty rates within Shaanxi but low levels of inequality within most counties and townships. We also investigate whether including environmental variables in the equation used to predict consumption and poverty improves upon typical approaches that only use household survey and census data. Ignoring environmental variables appears likely to produce targeting errors. |

| Título: | The value of statistical life and cost-benefit evaluations of landmine clearance in Cambodia |
| Fuente: | Environment and Development Economics. v.15, n.4. Beijer Institute of Ecological Economics; Royal Swedish Academy of Sciences |
| Páginas: | pp. 395-416 |

| Resumen: | Development agencies spend approximately US$ 400 million per year on landmine clearance. Yet many cost-benefit evaluations suggest that landmine clearance is socially wasteful because costs appear to far outweigh social benefits. This paper presents new estimates of the benefits of clearing landmines based on a contingent valuation survey in two provinces in rural Cambodia where we asked respondents questions that elicit their trade-offs between money and the risk of death from landmine accidents. The estimated Value of a Statistical Life (VSL) is US$ 0.4 million. In contrast, most previous studies of landmine clearance use foregone income or average GDP per capita, which has a lifetime value of only US$ 2,000 in Cambodia. Humanitarian landmine clearance emerges as a more attractive rural development policy when appropriate estimates of the VSL are used. |

| Título: | Measurement Error in Recall Surveys and the Relationship between Household Size and Food Demand |
| Fuente: | American Journal of Agricultural Economics. v.89, n.2. American Agricultural Economics Association |
| Páginas: | pp. 473-489 |
| Año: | 2007 |
| Resumen: | Variation in household survey design and implementation is used to obtain evidence of nonrandom measurement error in recall surveys of household expenditure. These surveys, which are used especially in developing countries, appear to have measurement errors in food expenditures and in food budget shares that are correlated with household size. These correlated errors may be part of the explanation for a puzzling pattern of falling food demand with rising household size in poorer countries. |
