This chapter provides an overview of the changes in nutrient content of the food supply in the United States and other countries. Core concepts used in assessment of the adequacy of (or excess in) diets and factors that affect nutrient availability in the food supply, including technology and...

In order to reduce obesity and associated costs, policymakers are considering various policies, including taxes, to change consumers’ high-calorie consumption habits. We investigate two tax policies aimed at reducing added sweetener consumption. Both a consumption tax on sweet goods and a...

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...

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...

This article measures the willingness to pay for the traceability of steers. I use data on the price of steers in Quebec and Ontario to identify a demand shifter in a hedonic framework. I estimate error correction models to provide the first market-based econometric estimates of the willingness...

The hypothesis that corn and soybeans have become more drought tolerant is tested by regressing county yields on a drought index and time. Results indicate that corn yield losses from drought of a given severity, whether measured in quantity terms or as a percentage of mean yields, have...

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