AbstractIn this paper we examine the levels and trends in agricultural output
and productivity in 93 developed and developing countries that account for a
major portion of the world population and agricultural output. We make use of
data drawn from the Food and Agriculture Organization of the United Nations and
our study covers the period 1980–2000. Due to the nonavailability of reliable
input pri... hiện toàn bộ
AbstractThis paper presents a spatial multi‐agent programming model, which has
been developed for assessing policy options in the diffusion of innovations and
resource use changes. Unlike conventional simulation tools used in agricultural
economics, the model class described here applies a multi‐agent/cellular
automata (CA) approach by using heterogeneous farm‐household models and
capturing their ... hiện toàn bộ

AbstractDoes access to off‐farm income complement or compete with agricultural
production? This article explores the effect of off‐farm income on agricultural
production activities, using data from the 2003 Mexico National Rural Household
Survey. We first discuss the theoretical conditions under which access to
off‐farm income may influence production in an agricultural household model.

AbstractThis paper intends to estimate the potential impact of climate change on
Taiwan's agricultural sector. Yield response regression models are used to
investigate the climate change's impact on 60 crops. A price‐endogenous
mathematical programming model is then used to simulate the welfare impacts of
yield changes under various climate change scenarios. Results suggest that both
warming and c... hiện toàn bộ
AbstractWe examine factors affecting the success and failure of collective
action toward the management of local commons. Using cross‐section survey data
on the activities of irrigators' associations in the Philippines, regression
analysis is conducted to identify factors underlying the success and failure in
farmers' organizing collective action for the maintenance and operation of
irrigation sys... hiện toàn bộ

AbstractIn this article, we draw out a set of axioms for food security
measurement that follow directly from the internationally agreed 1996 FAO
definition. Building on recent work on the theory and measurement of development
resilience, we then propose an empirical strategy to measure food security that
addresses these measurement axioms better than do prevailing measures. We
empirically illustra... hiện toàn bộ
AbstractThe purpose of this paper is to empirically track the progress and
consequences of the emergence of cultivated land markets in China since 2000. We
draw on a set of nationwide, household‐level panel data (for 2000 and 2008) and
find that the markets for cultivated land rental have emerged robustly.
According to our data, 19 of China's cultivated land was rented in farm
operators in 2008. W... hiện toàn bộ
AbstractIn recent years, there has been increasing emphasis in the rural
development literature on the multiple income‐generating activities undertaken
by rural households and the importance of assets in determining the capacity to
undertake these activities. Controlling for the endogeneity of activity choice
and applying Lee's generalisation of Amemiya's two‐step estimator to a
simultaneous equat... hiện toàn bộ
AbstractA large and growing share of the world's poor lives under conditions in
which high risk of natural hazards coincides with high vulnerability. As a
result natural disasters hit the poor disproportionately. In the last decade,
natural disasters claimed 79,000 lives each year and affected more than 200
million people, with damages amounting to almost US$70 billion annually. Experts
predict th... hiện toàn bộ
