Does exclusion matter in conservation agreements? A case of mangrove users in the Ecuadorian coast using participatory choice experiments.

Payments for environmental services (PES) constitute a growing approach to achieve the sustainability of ecosystems and the benefits they provide to people. However, informal tenure and lack of capacity to enforce property rights impede implementation of PES initiatives. Such challenges are common for local communities in coastal and marine areas who overexploit Common-Pool Resources (CPR) under open access. Assigning property rights to organized users has been implemented as a solution, transforming a public good into a club good.

Principios y valores constitucionales como marco de comprensión para la formación en competencias ciudadanas en Colombia a propósito de las pruebas Saber Pro

El objetivo del presente artículo es proponer una reflexión que contribuya a una mejor y más precisa comprensión de lo que implica la formación en competencias ciudadanas según lo evaluado en las Pruebas Saber. En la primera sección se reflexionará en torno a la función primordial en el orden axiológico político que tienen los valores y los principios constitucionales en la Carta política colombiana. En la segunda, se expondrán los diversos valores y principios constitucionales que deben servir de piso conceptual para el ejercicio pleno de la ciudadanía democrática.

Smallholder rice farmers’ post-harvest decisions: preferences and structural factors

We study post-harvest decisions among Tanzanian rice farmers. Risk and time preference experiments are used to understand post-harvest decisions. In particular, we investigate storage and processing decisions, which according to our study can increase income by more than 50 per cent, but also introduce risk and time delays. Experimentally elicited risk and time preferences are statistically significant in explaining these post-harvest decisions. Impatient farmers are less likely to store paddy, and risk-averse farmers are less likely both to process and store paddy for future sales.

Farm Diversification as an Adaptation Strategy to Climatic Shocks and Implications for Food Security in Northern Namibia

Limited non-farm opportunities in the rural areas of the developing world, coupled with population growth, means agriculture will continue to play a dominant role as a source of livelihood in these areas. Thus, while rural transformation has dominated recent literature as a way of improving welfare through diversifying into non-farm sectors, improving productivity and resilience to shocks in smallholder agricultural production cannot be  ownplayed.

The Impact of Forest and Non-Forest Land Cover on Potable Water Treatment Costs: Panel Evidence from Ethiopia

Empirical assessment of relationships between land use and land cover (LULC) and drinking water chemical treatment cost is lacking in developing countries. This study is conducted to assess the impact of forest and non-forest land cover on water purification chemical costs using panel data collected from eight drinking water treatment plants in Ethiopia for the period of 2002-2014. Forest cover and LULC data were extracted from Global Forest Change and GlobeLand30 datasets, respectively.

The Short-Run Subsidies, Take-Up, and Long-Run Demand for Off-Grid Solar for the Poor: Evidence from Large-Scale Randomized Trials in Rwanda

Over a billion people lack access to electricity, instead relying on kerosene and other dirty lighting sources, while grid expansion is not expected to keep pace with population growth. Moreover, pneumonia is the leading cause of death for under-fives in the world and kerosene smoke is a significant risk factor. For-profit distribution of low-cost solar LEDs has been suggested as a solution, but adoption remains low, especially by the poorest.

Weather Uncertainty and Demand for Information in Agricultural Technology Adoption: The Case of Namibia

Climate change has compounded the uncertainties inherent in agriculture. Farmers have to make decisions faced with increasingly fluctuating weather, leaving them vulnerable. Access to climate-related information in developing countries, incidentally also the hardest hit by the adverse effects of climate change, is very limited. Given a choice set of technologies that yield different payoffs depending on seasonal weather outcomes, ambiguity arising from imprecise weather information may lead to sub-optimal choices.

Competition and Gender in the Lab vs. Field: Experiments with Off-Grid Renewable Energy Entrepreneurs in Rural Rwanda

Applications of lab experiments to real-world phenomena are limited. We fill the gap by examining how gender attitudes and performance under competitive situations in the lab reflect microenterprise outcomes in the renewable energy sector of Rwanda – a country with progressive gender policies despite its traditional patriarchal setup. We use the standard Niederle and Vesterlund (2007) experimental design in addition to a unique dataset from off-grid microenterprises, managed by entrepreneurs who have been working in mixed and single-sex teams since 2016.

The Link Between Response Time and Choices in Choice Experiments

Response time is a possible indicator of the cognitive processes employed by choice experiment participants when making choices. The decision-making literature suggests a positive correlation between slower response time and rational thinking, which is consistent with standard theories of decision-making. The aim of this paper is to investigate the relationship between response time and respondents’ choices. We disentangle preference and willingness-to-pay estimates and explore whether response time sheds light on these aspects.
