EFFECTS AND DETERMINANTS OF MILD UNDERWEIGHT AMONG PRESCHOOL CHILDREN ACROSS COUNTRIES AND OVER TIME AgEcon
Bhagowalia, Priya; Chen, Susan E.; Masters, William J..
Research on malnutrition typically focuses on severe cases, where anthropometric status falls below or above an extreme threshold. Such categorization is necessary for clinicians since mild cases may not justify intervention, but researchers could find that changes in mild malnutrition convey valuable information about mortality risk and health status. This paper focuses on changes in both mild and severe underweight in young children, as measured by 130 DHS surveys for 53 countries over a period from 1986 to 2007. We find that counting variance in all forms of underweight provides closer correlations with aggregate health outcomes (the under-five child mortality rate), and is more closely correlated to several influences of malnutrition (national income,...

HOW SUCCESSFUL ARE GOVERNMENT INTERVENTIONS IN FOOD MARKETS? INSIGHTS FROM THE PHILIPPINE RICE MARKET AgEcon
Yao, Richard T.; Shively, Gerald E.; Masters, William J..
We investigate the Philippine government's price stabilization policy for rice. Seemingly Unrelated Regressions are used to examine the effectiveness of the program at regional and national levels over a 21-year period (January 1983 to December 2003). Results of the regional analysis indicate some NFA-induced spatial and temporal differences in terms of producer prices. The NFA successfully increased producer prices in 5 of 13 regions through stock accumulation and paddy rice purchase at floor prices. NFA stock releases do not correlate strongly with retail prices at the national level, although results from the regional model indicate that NFA stock releases reduced retail prices in five regions, leading to perceptible spatial and temporal differences...

Cartel Pricing with Entry: the Experience of the Far West Marketing Order for Spearmint AgEcon
Balagtas, Joseph Valdes; Masters, William J.; Zimmer, Timothy.
This paper documents the remarkable experience of the Far West mint producers in the operation of their marketing order. From 1993 to 2002, the marketing order witnessed a dramatic reduction its share of the Scotch spearmint market, as well as a reduction in both its price. We apply a model of a cartel facing a competitive fringe to describe the fall in the marketing order price as a logical consequence of increased world production of spearmint oil. We estimate an econometric model of the marketing order price and find that a 1-percent change in the marketing order's market share corresponds to a 0.8 percent change in the marketing order price.

TESTING THE LINK BETWEEN PUBLIC INTERVENTION AND FOOD PRICE VARIABILITY: EVIDENCE FROM RICE MARKETS IN THE PHILIPPINES AgEcon
Martinez, Elmer; Shively, Gerald E.; Masters, William J..
Monthly price data from the Philippines are used to test the influence of government buffer-stock programs on the level and variability of rice prices from 1974-1990. Results do not support the conjecture that prices were correlated with stock purchases.

Geography and Economic Transition: Global Spatial Analysis at the Grid Cell Level AgEcon
Motamed, Mesbah J.; Florax, Raymond J.G.M.; Masters, William J..
This paper addresses the timing of historical transition from rural to urban activity. In our model, rural production has constant returns and meets subsistence needs, while urban production has scale economies and meets the demands of higher-income consumers. Urbanization occurs sooner when rural or urban productivity is higher or transport costs are lower. We test the model on worldwide data that divides the earth's surface at half-degree intervals into over 60,000 cells. From an independent estimate of each cell's rural and urban population history, we identify the date at which each cell achieves various thresholds of urbanization. Controlling for country fixed effects and neighbors' urbanization using spatial techniques, we find that the date at which...

RESEARCH PRIZES: A MECHANISM TO REWARD INNOVATION IN AFRICAN AGRICULTURE AgEcon
Masters, William J..
This paper identifies market failures that limit agricultural R&D for Africa and other resource-poor environments, and proposes a mechanism to help circumvent them with cash prizes for the dissemination of successful innovations. The proposed prize institution would use ex-post experiments and farm surveys to document the value of innovations after their initial diffusion, to avoid pre-specification of technologies. Prizes would be offered in proportion to estimated social benefits, and would buy innovations into the public domain so that innovators with marketable technologies would choose not to apply for prizes. A governance structure to ensure credibility and financial sustainability is proposed.
