With farms cultivating tens or hundreds of thousands of hectares, Ukraine is often used to demonstrate the existence of economies of scale in modern grain production. Panel data analysis for all the country's farms with more than 200 hectares in 2001-2011 suggests that higher yields and profits...

Policies to tax farmers in low-income countries and policies to subsidize them in high-income countries have been identified as a major source of the disequilibrium of world agriculture. Recently, as many high-performing economies in Asia advanced from the low-income to the middle-income stage...

This paper uses the Ricardian approach to examine how farmers in 11 countries in Africa have adapted to existing climatic conditions. It then estimates the effects of predicted changes in climate while accounting for whatever farmer adaptation might occur. This study differs from earlier ones by...

This study employed the Ricardian approach to measure the economic impacts of climate change on farm net revenue in Egypt. Farm net revenue were regressed against climate, soil, socioeconomic and hydrological variables to determine which factors influence the variability of farm net revenues....

This report assesses the economic impacts of climate change on agriculture in Zambia, using the Ricardian method. A multiple linear regression model with net revenue per hectare as response variable has been fitted with climate, hydrological, soil, and socioeconomic variables as explanatory...

This paper summarizes the methods and findings of the hydrological assessment component of the project studying likely impacts of climate change on water resources and agriculture in Africa. The first phase of the study used a version of a conceptual rainfall-runoff model called WatBal (Water...

Previous Ricardian analyses of agriculture have either omitted irrigation or treated irrigation as though it is exogenous. In practice, it is a choice by farmers that is sensitive to climate. This paper develops a choice model of irrigation in the context of a Ricardian model of cropland. The...

Using cross-country and panel regressions, the authors show that financial sector development significantly reduces undernourishment (hunger), largely through gaining farmers and others access to productivity-enhancing equipment, translating into beneficial income and general effects. They show...

The relative contribution of a sector to poverty reduction is shown to depend on its direct and indirect growth effects as well as its participation effect. The paper assesses how these effects compare between agriculture and non-agriculture by reviewing the literature and by analyzing...

This paper brings together the literatures on the political economy of public expenditures and the determinants of economic growth. Based on a new dataset of rural public expenditures in a panel of Latin American economies, the econometric evidence suggests that non-social subsidies reduce...
