On average, U.S. farmers choose to apply nitrogen fertilizer at a rate that exceeds the ex post agronomically optimal rate. The technology underlying the yield response to nitrogen rewards producers who over apply in years when rainfall is excessive. The overapplication of nutrients has negative...

We compute the fertilizer use in corn, cotton, soybeans, and rapeseed in the period from 1990 to 2010 for a set of selected countries. In each case, we present the consumption of nitrogen, phosphate, and potash by crop and by year, reporting both the fertilizer application rates (in kilograms...

Finisher hog production in North America has seen a shift toward larger production units and contract-organized production since around 1990. Given the efficiency gains and conversion costs associated with contract production, growers may have to choose between long-term commitment through...

We introduce a world fertilizers model that is capable of producing fertilizer demand projections by crop, by country, by macronutrients, and by year. For each crop, the most relevant countries in terms of production, consumption, or trade are explicitly modeled. The remaining countries are...

We extend the existing literature on food taxes targeting obesity. We systematically incorporate the implicit substitution between added sugars and solid fats into a comprehensive food demand system and evaluate the effect of taxes on sugars and fats. The approach conditions how food and obesity...

We investigate factors affecting the duration of eating and food preparation among adults in single decision-maker households. Eating time is differentiated into primary and secondary eating time and further differentiated by location: at home vs. away from home. We construct a simple...

Past studies that examine the impact of ethanol mandates on fuel prices make the assumption that ethanol and gasoline are perfect substitutes because they are both sources of energy in transportation fuels. These studies, however, have been of limited use in informing current policy debates...

This paper models producers' interdependent incentives to participate in a voluntary livestock disease control program. Under strategic complementarity among participation decisions, after a slow start momentum can build such that market premium for participation and participation rate increase...

The U.S. crop insurance market has several features that set it apart from other insurance markets. These include:(a) explicit government subsidies with an average premium subsidy rate of about 60% in recent years; and (b) the legislative requirement that premium rates be set at actuarially fair...

There have long been concerns that federal crop insurance subsidies may significantly impact land use decisions. It is well known that classical insurance market information asymmetry problems can lead to a social excess of risky land entering crop production. We provide a conceptual model to...
