Fossil Fuel and Food Tax Incidence in Ethiopia

Most studies suggest that environmental taxes are regressive, making them less attractive policy options. The general objective of this paper is to analyze and compare fossil fuel and food tax incidence in Ethiopia in different expenditure groups of households considering urban and rural parts of Ethiopia separately.

    Curbing coca cultivation in Colombia — A framed field experiment

    This paper investigates the efficiency of carrot and stick policies to reduce investment in coca cultivation in rural Colombia. To measure behavioral responses to anti-drug policies, we conducted a framed field experiment with farmers living in one of the most important coca growing areas. Our experimental design allows identifying heterogeneous producer types and measuring their behavioral response to carrots and sticks. We provide an example on how knowledge on distribution types can be used to design an optimal anti-drug policy.

    Forest land rights, tenure types, and farmers' investment incentives in China: An empirical study of Fujian Province

    Purpose – The purpose of this study is to assess the impact of land rights and tenure types on farmers' investment behavior in Chinese collective forests, using household survey data from Fujian Province. Design/methodology/approach – In this study, the authors conducted a household survey in Fujian province of 520 randomly selected forest farmers. The authors used a random-effects Tobit model to estimate the impact of land rights and other components on, for example, tenure security and harvest quota, and the impact of tenure types on farmers' investment incentives.

    Dynamics of indirect land-use change: Empirical evidence from Brazil

    The expansion of a given land use may affect deforestation directly if forests are cleared to free land for this use, or indirectly, via the displacement of other land-use activities from non-forest areas towards the forest frontier. Unlike direct land conversion, indirect land-use changes affecting deforestation are not immediately observable. They require the linking of changes occurring in different regions.

    Integrating soil science into agricultural production frontiers

    This paper integrates soil science variables into an economic analysis of agricultural output among small-scale farmers in Kenya's highlands. The integration is valuable because farmers’ choice of inputs depends on both the status of the soil and socioeconomic conditions. The study uses a stochastic production frontier in which the individual farm's distance to the frontier depends systematically on individual factors.

    The Distributive Effect and Food Security Implications of Biofuels Investment in Ethiopia: A CGE Analysis

    In response to global opportunities and domestic challenges, Ethiopia is revising its energy policy to switch from high-cost imported fossil fuel to domestically produced biofuels. Currently, there are biofuel investment activities in different parts of the country to produce ethanol and biodiesel. However, there is no rigorous empirical study to assess impacts of such investments.

    Thanks but No Thanks: A New Policy to Avoid Land Conflict

    Land conflicts can be detrimental. An important goal of development policy is to help define and instill respect for borders. This is often implemented through mandatory and expensive interventions that rely on the expansion of government land administration institutions.

    The Supply of Inorganic Fertilizers to Smallholder Farmers in Tanzania, Evidence for Fertilizer Policy Development

    Inorganic fertilizer is one of a handful of agricultural technologies that have immense potential for raising the productivity of poor smallholders, enabling them to increase income, accumulate assets, and set themselves economically on a pathway out of poverty. This paper presents the results of a broad study of fertilizer supply to smallholder farmers in Tanzania that was done to assess whether the taxes (explicit or implicit) that are applied at various points along the fertilizer importation and marketing chain or the absence of key public goods and services reduces the access that smallholder farmers have to fertilizer. The study involved a review of the literature of fertilizer supply, demand, and use; interviews with key participants in fertilizer importation and marketing in Tanzania; and two surveys—one with farmers and the other with input suppliers—in three farming areas where more fertilizer is used than is the norm for the country as a whole

      Biodiversity, poverty, and development

      Biodiversity is crucial for the production of a range of marketed and non-marketed ecosystem goods and services. This paper reviews the empirical evidence for the role of terrestrial biodiversity and biodiversity conservation in economic development and poverty, at both the macro (e.g. country) and micro (e.g. farm) scales.

      Does eco-certification have environmental benefits? Organic coffee in Costa Rica

      Eco-certification of coffee, timber and other high-value agricultural commodities is increasingly widespread. In principle, it can improve commodity producers' environmental performance, even in countries where state regulation is weak. But eco-certification will have limited environmental benefits if, as one would expect, it disproportionately selects for producers already meeting certification standards.

      The impact of shadow prices and farmers' impatience on the allocation of a multipurpose renewable resource in Ethiopia

      In a mixed farming system in which farmyard manure (FYM) is considered an important multipurpose renewable resource that can be used to enhance soil organic matter, provide additional income and supply household energy, soil fertility depletion could take place within the perspective of the household allocation pattern of FYM. This paper estimates a system of FYM allocation regressions to examine the role of returns to FYM and farmers’ impatience on the propensity to allocate FYM to different uses.

      Nudging Boserup? The Impact of Fertilizer Subsidies on Investment in Soil and Water Conservation

      The new fertilizer subsidies in sub-Saharan Africa are intended to increase agricultural production and ensure development of a fertilizer market. Fertilizer adoption requires complementary inputs, such as investment in soil and water conservation (SWC), for efficient and optimal nutrient uptake, and many fertilizer subsidy programs implicitly assume that fertilizer subsidies crowd in such investments.

      Formal microlending and adverse (or non-existent) selection: A case study of shrimp farmers in Bangladesh

      Microcredit schemes have become a popular means of improving smallholders’ access to credit and making long term investment possible. However, it remains to be explored whether the current microcredit schemes are more successful than earlier formal small scale lending in identifying successful borrowers. We studied shrimp farming in a rural region in Bangladesh where formal microlending is well established, but where more expensive informal microlending coexists with the formal schemes.

      Assessing the Functioning of Land Rental Markets in Ethiopia

      Although a large theoretical literature discusses the possible inefficiency of sharecropping contracts, empirical evidence on this phenomenon has been ambiguous at best. Household‐level fixed‐effect estimates from about 8,500 plots operated by households that own and sharecrop land in the Ethiopian highlands provide support for the hypothesis of Marshallian inefficiency.

      Producer-level Benefits of Sustainability Certification

      Initiatives certifying that producers of goods and services adhere to defined environmental and social-welfare production standards are increasingly popular. According to proponents, these initiatives create financial incentives for producers to improve their environmental, social, and economic performance. We reviewed the evidence on whether these initiatives have such benefits.

      Importance of Irrigated Agriculture to the Ethiopian Economy: Capturing the direct net benefits of irrigation

      Irrigation development has been identified as an important tool to stimulate economic growth and rural development, and is considered as a cornerstone of food security and poverty reduction in Ethiopia. While a lot of effort is being exerted towards irrigation development, little attempt is being made to quantify the contribution of irrigation to national income. This study is an attempt in that direction by quantifying the actual and expected contribution of irrigation to the Ethiopian national economy for the 2005/2006 and 2009/2010 cropping seasons using the adjusted net gross margin analysis.

      Tenure security, resource poverty, public programs, and household plot-level conservation investments in the highlands of northern Ethiopia

      Land degradation poses a serious problem for the livelihoods of rural producers. Furthermore, there is rarely enough private investment taking place to commensurate the scale of the problem. This article examines the role of tenure insecurity, resource poverty, risk and time preferences, and community-led land conservation on differentiated patterns of household investment in land conservation in northern Ethiopia.

      The Effect of Ambiguous Risk and Coordination on Farmer´s Adaptation to Climate Change-A Framed Field Experiment

      The risk of losses of income and productive means due to adverse weather can differ significantly among farmers sharing a productive landscape, and is of course hard to estimate, or even “guesstimate” empirically. Moreover, the costs associated with investments in reduced vulnerability to climatic events are likely to exhibit economies of scope. We explore the implications of these characteristics on farmer's decisions to adapt to climate change using a framed field experiment applied to coffee farmers in Costa Rica. As expected, we find high levels of risk aversion, but even using that as a baseline, we further find that farmers behave even more cautiously when the setting is characterized by unknown or ambiguous risk (i.e. poor or non-reliable risk information). Secondly, we find that farmers, to a large extent, coordinated their decisions to secure a lower adaptation cost, and that communication among farmers strongly facilitated coordination.
