Direct and Spillover Effects of a Social Information Campaign on Residential Water-Savings

This paper investigates direct and spillover effects of a social information campaign aimed at encouraging residential water savings in Colombia. The campaign was organized as a randomized field experiment, consisting of monthly delivery of consumption reports, including normative messages, for one year. Results indicate that social information and appeals to norm-based behavior reduce water use by up to 6.8% in households directly targeted by the campaign.


Evaluation of the impact of fuelwood tree planting programmes in Tanzania

The rapid growth in Tree Planting for Fuelwood (TPF) program indicates the importance of taking care of the increasing demand for fuelwood globally. TPF programs in Tanzania aim to sustainably meet the rising demand for fuelwood. We evaluate the impact of TPF programs on the number of trees planted and those planted for fuelwood. Using survey data, we employ the Heckman and Propensity Score Matching techniques to estimate whether households plant trees for fuelwood and can identify tree species that would influence them to plant trees.


Factura electrónica en América Latina

La factura electrónica fiscal (FE) es uno de los aportes de América Latina a la fiscalidad internacional en apoyo a la lucha contra la evasión, al esfuerzo global de transparencia tributaria, y a la digitalización de las administraciones tributarias (AATT). Inicialmente, la FE fue concebida como un instrumento de control documental del proceso de facturación, tanto para evitar la omisión de ventas como para la inclusión de compras falsas.


Roads & SDGs, tradeoffs and synergies: learning from Brazil’s Amazon in distinguishing frontiers

To reduce SDG tradeoffs in infrastructure provision, and to inform searches for SDG synergies, the authors show that roads’ impacts on Brazilian Amazon forests varied significantly across frontiers. Impacts varied predictably with prior development – prior roads and prior deforestation – and, further, in a pattern that suggests a potential synergy for roads between forests and urban growth. For multiple periods of roads investments, the authors estimate forest impacts for high, medium and low prior roads and deforestation. For each setting, census-tract observations are numerous.


Difference in Preferences or Multiple Preference Orderings? Comparing Choices of Environmental Bureaucrats, Recreational Anglers, and the Public

Abstract Do Environmental Protection Agency (EPA) bureaucrats represent the general public or are they more in line with an interest group? We study preferences for environmental policy using a choice experiment (CE) on three populations; the general public, Swedish EPA bureaucrats, and recreational anglers. We also test for existence of multiple preference orderings: Half of the respondents were asked to choose the alternatives that best corresponded with their opinion, and the other half was asked to take the role of a policy-maker and make recommendations for environmental policy. The SEPA bureaucrats have the highest marginal willingness to pay (MWTP) to improve environmental quality. Differences in MWTP are robust and not due to differences in socio-economic characteristics across the populations. We only found weak evidence of multiple preference orderings.


Climate change impacts and adaptation among smallholder farmers in Central America

Smallholder farmers are one of the most vulnerable groups to climate change, yet efforts to support farmer adaptation are hindered by the lack of information on how they are experiencing and responding to climate change. More information is needed on how different types of smallholder farmers vary in their perceptions and responses to climate change, and how to tailor adaptation programs to different smallholder farmer contexts.


    Do Safety Net Transfers Improve Diets and Reduce Undernutrition? Evidence from Rural Ethiopia

    This paper we examine the impact of the Ethiopia’s Productive Safety Net Program (PSNP) on household dietary diversity and child nutrition using both waves of the Ethiopian Socioeconomic Survey. It uses various methodologies. Results indicate consistently that PSNP has not had the desired effect on household dietary diversity or child nutrition regardless of model specification or methodology, suggesting that perhaps the transfers need to be paired with additional interventions such as information about nutrition.


    Context Matters: Exploring the Cost-effectiveness of Fixed Payments and Procurement Auctions for PES

    Successfully implemented payment for ecosystem services (PES) programs can provide both conservation of nature and financial support to rural communities. In this paper, we explore how PES programs can be designed so as to maximize the amount of additional ecosystem services provided for a given budget. We also provide a brief summary of the use of auction mechanisms in real world PES programs.


    A Contingent Valuation Approach to Estimating Regulatory Costs: Mexico's Day Without Driving Program

    Little is known about the cost of environmental regulations that target households instead of firms, partly because of significant methodological and data challenges. We use the contingent valuation method to measure the costs of Mexico City’s Day without Driving program, which seeks to stem pollution and traffic congestion by prohibiting vehicles from being driven one day each week. To our knowledge, ours is the first study to focus directly on using stated preference methods to isolate and estimate the private costs of an existing environmental regulation.


    Lessons from Applying Market-Based Incentives in Watershed Management

    Watershed management is a complex activity with constraints on funding and human resources in many parts of the world, and there is a need for global effort to identify strategies that can work. To complement regulatory approaches, attention is now also being given to market-based incentives because of their potential cost-effectiveness. This study seeks to provide impetus to the use of the most successful market-based incentives to promote sustainable watershed practices through strengthening and increasing direct participation
