This study has been undertaken to understand and evaluate the potential negative consequences of export taxes which are implemented by many countries today and which are not disciplined by any international agreement. This paper uses a new detailed global dataset on export taxes at the HS6 (Harmonized System 6 level) level and the MIRAGE (Modeling International Relationships in Applied General Equilibrium) global computable general equilibrium model to assess the impact of export taxes on the world economy. We find that limitations on export taxes would have worldwide effects: the average export tax on global merchandise trade was 0.48 percent in 2007, with the bulk of these taxes imposed on energy products. The removal of these taxes would increase global welfare by 0.23 percent, which is a larger figure than the expected gains from the World Trade Organization’s Doha Development Round. Both developed and emerging economies, such as China and India, would gain from such policies, even if they currently impose export taxes. Medium and small food-importing countries without market power (such as the least-developed countries) would also benefit from the elimination of export restrictions, especially during food crisis situations. Both the energy sector and the export taxes implemented by Commonwealth of Independent States countries appear to play a critical role in the overall economic impact of such a policy change. However, the fact that some countries, such as Argentina, would experience income losses due to such a policy change is a major challenge to overall positive reform in this area.

Despite years of development interventions, agricultural productivity in Africa south of the Sahara still trails far behind all other continents, leaving many rural populations in dire poverty. This suggests that our understanding of the impacts of agricultural development projects is still imperfect; perfecting it is likely to be a crucial step in achieving development. Projects that raise agricultural productivity, in addition to directly affecting farmers, can have an impact on local prices, wages, and rents, especially in rural areas of Africa, which tend to be less-than-perfectly integrated with outside markets. Price changes, in turn, transmit project impacts to others within the local economy. This paper presents the findings of a local economywide impact evaluation of Feed the Future irrigation projects in the Morogoro region of Tanzania, using a local economy-wide impact evaluation (LEWIE) simulation model. The findings indicate that these irrigation projects can generate important indirect impacts within the region. The structure of local markets, as well as labor and land availability, shapes project spillovers in ways that point to future directions for development assistance in the region.

The second annual Africa Agriculture Trade Monitor assesses emerging and long-term trends and drivers shaping Africa’s trade in agricultural products and evaluates the possible impacts of current trade tensions. The 2019 report focuses on intraregional trade and competitiveness, with chapters on measuring regional trade integration and competitiveness of agriculture, a feature chapter on the potential impact of global trade tensions, and an in-depth look at trade integration in the Eastern and Southern Africa region.

Vietnam is likely to be among the countries hardest hit by climate change, threatening its legacy as a champion in leveraging agriculture for development. This paper examines how a changing climate may affect rice production and how Vietnamese farmers are likely to adapt to various climatic conditions using an innovative yield function approach, taking into account sample selection bias and endogeneity of inputs. Model results suggest that although climate change can potentially reduce rice production, farmers will respond mainly by adjusting the production portfolio and levels of input use. However, investments in rural infrastructure and human capital will have to support farmers in the adaptation process if production levels and farm incomes are to be sustained in the future.

Using data from multiple sources, we show that in Bangladesh, the increase in real wages, particularly female wages, has accelerated since the late 2000s, suggesting that the Lewis turning point (the point at which the labor market starts to shift in favor of workers) has arrived in Bangladesh. Rising wages are likely a result of a combination of more ample job opportunities in the nonfarm sector, especially in the manufacturing sector for females, and a greater amount of remittances, primarily from male workers overseas. Since human capital is the most important asset for the poor, the escalation in real wages has boosted the poor’s earnings, thereby reducing their likelihood of being poor.

Asian countries have witnessed a sharp increase in real wage as a result of rapid economic growth and structural transformation in recent years. Using a country level panel data from 1980 to 2010, this paper examines the effects of real wage increase on Asian agriculture that traditionally used family labor intensively on small farms. The empirical evidence supports our hypothesis that an increase in real wages, along with absorptions of labor into nonagricultural sectors, has been inducing the substitution of labor by machines in agriculture. However, this process is less successful in the countries that are constrained by their small operational land sizes, resulting in lowered land productivity. We also demonstrated that dynamic changes in yield are an important determinant of food self-sufficiency ratio. The above findings imply that in the near future, Asian agriculture can face a challenge in maintaining domestic food production. Given the large size of consumer demands in the region and its increasing trend, the future path of Asian agriculture could be a significant constraint on the global food supply–demand balance.

It is widely agreed that reducing poverty in Africa south of the Sahara (SSA) depends largely on stimulating growth in agriculture. To this end, heads of state in Africa rallied to form the pan-African Comprehensive African Agriculture Development Programme (CAADP) with the goal of raising investments and improving strategy implementation. However, while implementing an agricultural agenda under the CAADP framework, more and more countries have realized that increasing public investment in agriculture alone is not enough. Policy can play an important role not only to make public investment more efficient, but also is crucial for incentivizing private sector and farmer investment in agriculture. Against this backdrop this paper takes stock of current agricultural policies in SSA with a view to identifying policies that are working as well as areas for improvement. The paper examines policies to encourage the adoption of agricultural inputs, initiate greater private-sector investment in agriculture and agro-industries, and manage price volatility while encouraging openness. The paper further reviews successful land tenure policies and property rights systems, reviews the evidence on the synergies between agriculture and nutrition, and examines how CAADP is laying the institutional architecture for improved policy formulation in Africa. In general, the paper finds that although substantial progress has been made, there is considerable scope for improvement. This is not surprising given the relatively primitive and deeply rooted nature of smallholder farming in Africa. Evidence synthesized in the paper supports the view that most policies cannot be implemented in isolation. Rather, policies tend to be most effective when implemented along with complementary policies and public investments.

Though there is increasing evidence of the availability and potential of new agricultural technologies in Africa south of the Sahara, effective demand for them is still low. A recent refocus on increasing farmers’ use of modern technologies such as improved seed and chemical fertilizer has led to a resurgence of input subsidies for these products in many developing countries. One popular mechanism currently in use is input vouchers. Targeted input vouchers are intended to simultaneously improve the targeting of subsidies and develop demand in private markets. While there is growing evidence of the impact of targeted subsidies on private input demand, as far as we are aware no empirical studies have examined the spillover effects of targeted subsidies for just one input on the use of other complementary inputs with which there is low substitutability. Consequently, this study begins to fill this gap by exploring the effect of increasing access to subsidized fertilizer on farmers’ use of improved seed in Nigeria. Using a control function approach within a limited dependent variable framework, we explore the effect of receiving subsidized fertilizer on a farmer’s likelihood of using improved seed. The study finds evidence that increased access to subsidized fertilizer increased the likelihood of farmers using improved seed in Kano, Nigeria. This indicates that farmers are re-optimizing their use of other inputs in response to increasing availability of one input. This complicates the ability to isolate the returns to any one input when evaluating programs targeted at just one input. Our results were robust to various model specifications and indicate that there is a clear link between farmers’ use of improved seed and fertilizer in Kano, which could be leveraged in the development of input subsidy programs across Africa south of the Sahara.

In this paper, we provide an overview of the agricultural trade negotiations within the current World Trade Organization (WTO) negotiations and we show that including agriculture in the Doha Development Agenda talks is important both economically and politically, although the political resistance to reform is particularly strong in this sector. While agriculture accounts for less than 10 percent of merchandise trade, high and variable agricultural distortions appear to cause the majority of the cost of distortions to global merchandise trade. Within agriculture, most of the costs appear to arise from trade barriers levied on imports, since these barriers tend to be high, variable across time and over products, and levied by a wide range of countries. The negotiations face a need for balance between discipline in reducing tariffs—hence creating the market access gains that are central to the negotiations—and flexibility in managing political pressures. While the approach of providing flexibility on a certain percentage of tariff lines is seriously flawed, the proposed modalities still appear to provide worthwhile market access. Better ways appear to be needed to deal with developing countries’ concerns about food price volatility while reducing the collective-action problems resulting from price insulation.
