Limitations of Certification and Supply Chain Standards for Environmental Protection in Commodity Crop Production
Vol. 6 (2014), pp. 429–449More LessMotivated by recent increases in water pollution in major US agricultural watersheds and by the shortcomings of government programs to control non–point source pollution, this paper examines the prospects for using product certification (ecolabeling) and business-to-business supply chain standards for environmental protection in commodity crop production. We introduce the sources of demand for certification and supply chain standards and the political and economic context in which they have expanded since the 1990s. We explore how various agrifood certification and supply chain standards have been used to achieve changes in production methods and/or in product attributes to meet social goals, and we discuss the prospects for applying these models to commodity crops. We conclude that the nature of corn and soybean production, distribution, and consumption—with numerous sales outlets and invisible consumption as part of processed foods and other products—makes certification schemes to limit agricultural pollution unrealistic and supply chain standards extremely challenging.

Theory and Application of Positive Mathematical Programming in Agriculture and the Environment
Vol. 6 (2014), pp. 451–470More LessThis review critically looks at the theoretical and empirical foundations of positive mathematical programming and its evolution in the past decade or so. We show how the need to model new empirical phenomena has induced the literature to rethink model specifications and to address new questions in the area of calibrated programming. We also raise a number of modeling questions that, in our view, ought to be addressed in future research.

Agriculture in African Development: Theories and Strategies
Vol. 6 (2014), pp. 471–492More LessAgriculture is the largest sector in most sub-Saharan economies in terms of employment, and it plays an important role in supplying food and export earnings. Rural poverty rates remain high, and labor productivity is strikingly low. This article asks how these factors shape the role of agriculture in African development strategies. Is agricultural growth a prerequisite for growth in other sectors? Or will urbanization and nonagricultural export markets ultimately be the forces that pull the rural economy into higher productivity? We argue that agricultural development strategies will vary widely because of heterogeneity across and within countries.

Trade Liberalization and Poverty: What Have We Learned in a Decade?
Vol. 6 (2014), pp. 493–512More LessThis article reviews key recent literature on the effects of trade liberalization on poverty in developing countries and asks whether our knowledge has changed significantly over a decade. The conclusion that liberalization generally boosts income and thus reduces poverty has not changed; some authors suggest that this finding is not true for very poor countries, but this suggestion is far from proven at present. With regard to microeconomics, recent literature again confirms that liberalization has very heterogeneous effects on poor households, depending, inter alia, on what trade policies are liberalized and how the household earns its living. Working in the export sector predicts gains, and working in the import-competing sector predicts losses, a finding that is reinforced by studies of the effects of liberalization on wages. New research has suggested several ways in which intrasectoral wage inequality is increased by trade, but this research generally does not indicate that the poor actually lose. A fairly common finding is that female workers gain from trade liberalization.

The Intersection of Trade Policy, Price Volatility, and Food Security
Vol. 6 (2014), pp. 513–532More LessThe volatility of food prices has always concerned national governments, especially those of open developing economies, as it undermines their perceived national food security. A common policy approach has been to partially insulate their domestic market from international food price fluctuations by varying restrictions on their imports or exports. Unfortunately, such domestic stabilization measures amplify international price fluctuations. This article explains conceptually, and illustrates empirically, how insulation measures do little to advance national food security and collectively imperil global food security. Many countries also intervene to alter the trend level of domestic farm product prices, again most commonly with the use of trade restrictions. The latter policies have the unintended consequence of thinning international food markets, adding to their volatility. The article concludes by pointing to alternative ways for governments to boost food security for vulnerable households; such alternatives have become far more feasible in recent times, thanks to the information and communication technology revolution.

The Power of Information: The ICT Revolution in Agricultural Development
Vol. 6 (2014), pp. 533–550More LessWe review the state of information and communication technologies (ICTs) and their impact on agricultural development in developing countries, documenting the rapid changes that have taken place over the past decade. Although there remains a wide gap in access between rural and urban areas, the spread of mobile phones in rural areas has led to important changes in the agricultural sector. We find that access to mobile phones has generally improved agricultural market performance at the macro level; however, impacts at the micro level are mixed. Evidence regarding the impact of market information systems (MIS) delivered through mobile phones on farm prices and income is limited, but the evidence points to strong, heterogeneous impacts. Similarly, the rollout of extension programs though ICTs is still in an early stage, and little research is available regarding such programs’ impacts.
