The paper extends the methodology of parametric decomposition of the Malmquist productivity index using an output distance function. This approach addresses common methodological issues in total factor productivity estimation to produce credible and relevant results. The Malmquist index can be decomposed into several components: technical change (further broken down into technical change magnitude, input bias, and output bias), technical efficiency change, scale efficiency change, and output-mix effect. A translog output distance function is chosen to represent the production technology, and each component of the Malmquist index is computed using the estimated parameters. This parametric approach allows us to statistically test hypotheses regarding different components of the Malmquist index and the nature of production technology. The empirical application to Chinese agriculture shows that productivity grows at 2 percent per year on average from 1978 through 2010. The growth is mostly driven by technical change, which is found to be technology neutral.

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.

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 supplydemand balance.

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 poors earnings, thereby reducing their likelihood of being poor.

The purpose of the research summarized in this paper is to provide policy-relevant knowledge on the governance of rural services in Guatemala and thus to contribute to improving the provision of services that are essential for agricultural and rural development. Almost 10 years ago, the Guatemalan government decided to strengthen decentralization and community participation to improve the quality of public services, as well as access to these services for the poor, especially in rural areas. Based on quantitative and qualitative primary data, we examine how services are actually provided today and how community preferences and participation affect service provision in rural Guatemala. Our main finding is that the provision of formally decentralized services by local governments is incomplete. As a result, many rural communities continue to lack access to services, and some of them engage in supplying these services themselves. However, communities do not consider themselves to be more effective at service provision and would therefore prefer to be served by the government. Moreover, we find that community participation in the planning and evaluation of services has a positive impact on the responsiveness of the local governments service provision. However, the effectiveness of community participation varies greatly among the examined cases, with several participatory governance bodies not functioning properly due to low education levels, poverty, and weak civil-society organization.

The Malawian economy has in recent months been plagued by a severe foreign exchange crisis, fueled in part by a steadily rising import bill, sharp successive declines in tobacco export prices, the suspension of direct government budget support from several development partners in 2011, and an all-time low in international investor confidence. Up until the regime change in April 2012, the government resisted calls for a devaluation, which at the time resulted in a thriving parallel foreign exchange market. At its peak, the Malawi kwacha was trading at a premium of up to 100 percent in this secondary market. Economic theory shows that such a situation has adverse implications for an economy in terms of the balance-of-payments adjustment process and income distribution in the economy. Those with access to foreign exchange at the official rate are able to extract rents by selling foreign currency or imported goods at inflated prices. Imports sold domestically are then often valued at the parallel exchange rate rather than the official rate, with the parallel market rate serving as the only adjustment mechanism through which equilibrium can be restored in the balance of payments. This has a significant impact on domestic inflation to the detriment of consumers, while those with preferential access to foreign exchange at the official rate capture large rents. A simulation exercise using an economywide model for Malawi considers how the economy responds to different types of foreign exchange shocks under fixed and flexible exchange rate regimes. While the foreign exchange crisis in itself has severe negative implications for the economy, our results suggest that the economy responds much better to these types of shocks under a flexible exchange rate regime (that is, devaluations or a free-floating currency). Our main simulation shows that under the latter policy, gross domestic product growth, although negative, is 1.5 percentage points higher than under a fixed exchange rate policy. Similarly, poverty is 6.9 percentage points lower. A relaxation of the exchange rate policy, however, is only part of the solution; in the longer run, good governance and sound macroeconomic policy that is conducive to growth are needed to address the underlying structural problems in the economy that also contribute to foreign exchange shortages.

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 tariffshence creating the market access gains that are central to the negotiationsand 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.
