In the context of bovine tuberculosis (bTB) control in New Zealand cattle, we address the problem of management under uncertain disease prevalence by integrating a model of disease transmission and Bayesian learning from testing. We show the implications of accounting for the full dynamic value...

Variations in different household expenditures across urban households in the Republic of Uganda are studied using a survey data. Multivariate Tobit estimation method is employed to quantify the effects of various factors, including household income. Expenditure elasticities of income vary...

The objective of the study is twofold: first, to investigate whether a nutrition convergence process exists in sub Saharan Africa (SSA) countries, and second, to examine the response of per capita nutrient intake [i.e. calories, proteins and fats] to changes in income (i.e. nutrient-income...

Climate change will directly affect food availability and security. Because food production is fundamentally a biological process that is a function, in part, of temperature and moisture, the agricultural sector’s potential vulnerability is particularly large. While there is ongoing scientific...

During the Global Food Price Crisis of 2007-2011, millions of people suffered from hunger because food had become expensive. To cope with this problem, the governments of several countries decided to establish public food reserves in order to stabilize domestic prices. In this paper we develop a...

We empirically address the implications of biofuel policy regarding major grains, to the subsequent evolution of the markets for calories from the three major grains, maize, wheat and rice. The implied market variables, namely, market price, consumption, and stocks, using a structurally...

In this paper we first study where food purchases are made by SNAP recipients in comparison to eligible and ineligible non-SNAP recipients. Particularly, we analyze whether SNAP recipients use retail food outlets which generally have lower prices and how far they travel to purchase food. We next...

This paper builds a model determining optimal capacities of diversion dams or water transfer projects. The model incorporates stochastic inflows to the dams and the role of the dam capacity in reducing overflows, and gives a closed-form expression of the marginal benefit of capacities....

We investigate to which extent the Agricultural Market Information System (AMIS), set up by the G20 in 2011, can help to reduce food price volatility. Linking uncertainty about fundamentals and volatility in a theoretical model, we show that the uncertainty provides an upper limit for the...

In the U.S., many households are unable to meet their dietary needs for leading an active and healthy lifestyle. Research has focused on assessing community-level constraints and opportunities to access health and nutritious food for low-income and disadvantaged populations. Our aim is to...
