In this article we perform production efficiency analysis for the 40 countries with largest value added by agricultural sector in 2005. Under the assumption of a nonparametric frontier and production observations satisfying a statistical model including both random and inefficiency errors, we estimate an agricultural production function using DEA measures of efficiency with output orientation and variable returns to scale. We found evidence that the set of countries investigated could increase their total value added by agricultural sector for at least 53.9% without increasing input usage with the prevailing technology. This result has a direct impact on issues related to the recent food crisis.

The fourteenth joint edition of the OECD-FAO Agricultural Outlook provides market projections for major agricultural commodities, biofuels and fish, as well as a special feature on the prospects and challenges of agriculture and fisheries in the Middle East and North Africa.

The Agricultural Outlook 2021-2030 is a collaborative effort of the Organisation for Economic Co-operation and Development (OECD) and the Food and Agriculture Organization (FAO) of the United Nations. It brings together the commodity, policy and country expertise of both organisations as well as input from collaborating member countries to provide an annual assessment of the prospects for the coming decade of national, regional and global agricultural commodity markets. The publication consists of 11 Chapters; Chapter 1 covers agricultural and food markets; Chapter 2 provides regional outlooks and the remaining chapters are dedicated to individual commodities.

This paper provides an assessment of the South African potential output for the period 1985-2010 by applying both structural and nonstructural estimation techniques. The analysis suggests that, while potential output growth steadily accelerated in the post-apartheid era to about 3 1/2 percent (1994-2008), it has decelerated considerably following the outbreak of the financial crisis, as was observed in other advanced and emerging economies. While this indicates that, at around -1 1/ 2 percent, the estimated 2010 output gap was lower than previously thought, there is a fair amount of uncertainty regarding its "true" magnitude, reflecting in part the backward looking nature of the estimation methods. The paper concludes that the potential growth is likely to gradually revert to its precrisis pace and the output gap to have closed by early 2012.

In this book we assemble a range of evidence from a range of sources with a view to developing an improved understanding of recent trends in agricultural productivity around the world. The fundamental purpose is to better understand the nature of the long-term growth in the supply of food and its principal determinants. We pursue this purpose from two perspectives. One is from a general interest in the world food situation in the long run. The other is from an interest in the implications of U.S. and global productivity patterns for U.S. agriculture.

This paper investigates the macroeconomic cycles China has experienced since the onset of reform in the late 1970s. It finds that the recurrent inflationary episodes that characterize the cycles are associated primarily with surges in the main components of aggregate demand. The most recent cycle stands out in achieving for the first time a reduction in inflation without a major slowdown in growth. The soft landing was facilitated by a number of factors, including increases in capacity as a result of the surge in investment spending early on in the cycle.
