Investigating Retail Price Premiums for Organic Foods

Retail price premiums for selected organic foods, 2010 chart

The Economic Research Service used grocery store purchase data to estimate retail price premiums for 17 commonly purchased organic foods relative to their nonorganic counterparts from 2004 to 2010.

Consumer demand for organically produced goods has shown double-digit growth during most years since the 1990s, according to industry statistics, providing market incentives for U.S. farmers across a broad range of products. Consumers can now purchase organic food at nearly three out of four conventional grocery stores. These products generally carry a price that reflects the additional costs of producing organic foods and of keeping products segregated throughout the supply chain. The price premiums reflect these costs as well as consumers’ willingness to pay more for organic products.

A new Economic Research Service report provides estimated retail price premiums—and changes in premiums—for 17 commonly purchased organic foods relative to their nonorganic counterparts from 2004 to 2010. We used grocery store purchase data from a large set of nationally representative households. The data included detailed information on each product (degree of processing, flavor, package size, and whether organic), its price, and where it was purchased, allowing us to isolate the organic price premium.

Students Intrigued Enough to ‘Worm’ Their Way into Ag Science

The goal of USDA’s Hispanic-Serving Institutions National Program (HSINP) Future Scientists Program is to enhance the scientific knowledge of teachers, helping them to become more effective in encouraging student interest and progress in science. Teachers in the program attend two-day summer institutes at Agricultural Research Service (ARS) labs nationwide, where scientists introduce them to various research projects. ARS researchers share scientific knowledge with the teachers, who then share it with their students to encourage them to become future scientists.

One of the catalysts for this lofty goal is a tiny, inconspicuous and innocuous caterpillar—the corn earworm that wreaks havoc in corn fields nationwide as an agricultural pest.  This program began in 2003.  I brought 10 teachers into the ARS Southern Plains Agricultural Research Center (SPARC) in College Station, Texas, for a summer institute that included teachers studying in corn research plots searching for corn earworm caterpillars in 100-degree heat! It was the first time I made caterpillars the focus of this program.

Responding to Climate Variability is one of the goal areas of the REE Action Plan.  The objective is to develop science-based knowledge to address climate variability, position agricultural communities to reduce emissions of greenhouse gases, and enhance carbon sequestration.

Many valuable USDA accomplishments for the year 2015 were the result of cross-divisional teams that developed useful tools to support decision-makers with research-based data.  Knowing weather and climate patterns–driving forces behind the success or failure of cropping systems–is vital information to land managers.  One such tool, AgroClimate, supported by REE and the National Oceanic and Atmospheric Administration (NOAA), helps users manage climate risk with tools that provide information on crops best suited to grow in their region, based on water availability and the amount of water a crop will use.

‘Soil and Air’ – Where Crops Meet the Environment

You probably know that climate change affects how we grow food, but you might not know that how food is grown also affects our climate. This interplay is at the heart of an Agricultural Research Service (ARS) project called “Soil and Air,” a concerted effort to feed the Earth’s 7.5 billion people while protecting the planet.

Farmers and ranchers produce food at the intersection of soil and air, which in turn impacts soil and air quality. For instance, warmer air creates warmer soil, leading to different compositions of bacteria and other microbes in the ecosystem and to increased moisture loss through evaporation. Read more »

Proactive Efforts by U.S. Federal Agencies Enable Early Detection of New Antibiotic Resistance

Just over a year ago, President Obama released a National Action Plan for Combating Antibiotic Resistant Bacteria. As part of that plan, he also charged the Department of Defense (DoD), Department of Agriculture (USDA) and Department of Health and Human Services (HHS) with co-chairing a Presidential Advisory Council on Combating Antibiotic-Resistant Bacteria (Advisory Council). In the past year, our three agencies and the Council have held numerous stakeholder meetings, made new discoveries, and undertaken new research to preserve the effectiveness of antibiotics.

In recent weeks, our three agencies have made some important discoveries regarding antibiotic resistance in the United States. Earlier this week, the Department of Defense notified stakeholders that its Multidrug-resistant Organism Repository and Surveillance Network (MRSN) at the Walter Reed Institute of Research had identified the first colistin-resistant mcr-1 E. coli in a person in the United States. A USDA and HHS search for colistin-resistant bacteria in food animals, retail meats and people also has found colistin-resistant E. coli in a single sample from a pig intestine. Read more »
