AbstractWe adopt an EASI model to estimate demand for omega-3, organic, cage-free, and conventional eggs in the United States. Our empirical framework accounts for demand inter-dependencies among these egg types, while allowing for unrestricted Engel curves, unobserved consumer heterogeneity, and a broader product and geographic coverage. We further address endogeneity of prices and expenditures and left-censoring induced by disaggregate data. Our results indicate that the demand for organic and cage-free eggs is price-elastic, while the demand for omega-3 and conventional eggs is price-inelastic. Additionally, we establish strong substitutability relationships between the eggs. Finally, we measure consumer welfare consequences of rising domestic egg prices brought by Japan’s egg import tariff reductions.

People have been eating eggs for centuries. Records as far back as 1400 BC show that the Chinese and Egyptians raised birds for their eggs. The first domesticated birds to reach the Americas arrived in 1493 on Christopher Columbus' second voyage to the New World. Most food stores in the United States offer many varieties of chicken eggs to choose from — white, brown, organic, cage free, vegetarian, omega-3 fatty acid enriched, and more. The bottom line is that buying eggs is not as simple as it used to be because more choices exist today. This 4-page fact sheet will help you understand the choices you have as a consumer, so you can determine which variety of egg suits you and your family best.

Humans under-consume fish, especially species high in long-chain omega-3 fatty acids. Food-based dietary guidelines are one means for nations to encourage the consumption of healthy, nutritious food. Here, associations between dietary omega-3 consumption and food-based dietary guidelines, gross domestic product, the ranked price of fish, and the proportions of marine fish available at a national level were assessed. Minor associations were found between consumption and variables, except for food-based dietary guidelines, where calling out seafood in FBDGs did not associate with greater consumption. This relationship was explored for consumers in the United States, and it was observed that the predominant seafood they ate, shrimp, resulted in little benefit for dietary omega-3 consumption. Seafood is listed under the protein category in the U.S. Dietary Guidelines, and aggregating seafood under this category may limit a more complete understanding of its nutrient benefits beyond protein.

Studies have assessed omega-3 fatty acids and cognitive decline among older adults and cognitive development among children, although less is known about cognitive or neurological effects among young adults. We examined whether omega-3 supplementation from krill oil could improve cognition and resilience among young military officers compared to a control. This double-blind, placebo-controlled trial enrolled 555 officers (mean age 23.4 ± 2.8, 98.6% male) entering the United States (US) Army Infantry Basic Officer Leaders Course (IBOLC) with the intention to complete the US Ranger Course. Volunteer participants consumed eight dietary supplements daily of krill oil containing 2.3 g omega-3 or control (macadamia nut oil) over an approximate 20-week period. Cognitive functioning, resilience, and mood were assessed during a well-rested period at approximately 14 weeks and after a battlefield simulation at 16 weeks. Blood spot samples were collected to monitor compliance and dietary intake was assessed. All hypotheses were tested using both ‘Intention to Treat’ (ITT) and ‘As Per Protocol’ (APP) approaches. Of the 555 randomized individuals, 245 (44.1%) completed the study. No statistically significant group-by-time interactions indicating treatment effect were found on any outcomes. Poor compliance was indicated by lower than expected omega-3 elevations in the treatment group, and may have contributed to a failure to detect a response.

Most countries are members of preferential trade agreements (PTAs). The effect of these agreements has attracted much interest and raised the question of whether PTAs promote or slow multilateral trade liberalization, i.e., whether they are a “building block” or “stumbling block” to multilateral liberalization. Despite this long-standing concern with PTAs and the lack of theoretical consensus, there is no systematic evidence on whether they are actually a stumbling block to multilateral liberalization. We use detailed data on U.S. multilateral tariffs to provide the first systematic evidence that the direct effect of PTAs was to generate a stumbling block to its MTL. We also provide evidence of reciprocity in multilateral tariff reductions.

Green roofs are becoming increasingly prevalent in the United States due to their economical and environmental benefits as compared with conventional roofs. Plant selection for green roofs in the variable climate of the southeastern United States has not been well evaluated. Shallow substrates on green roofs provide less moderation of temperature and soil moisture than deeper soils in traditional landscapes, necessitating empirical evaluation in green roof environments to make informed recommendations for green roof plant selection. Nineteen species and cultivars, including succulents, grasses, and forbs, were evaluated under seasonal irrigated and non-irrigated conditions in experimental green roofs. Plants were planted on 26 Oct. 2009 and each evaluated for survival and increase in two-dimensional coverage of the substrate during establishment, after overwintering, and after the first growing season. The winter 2009–10 was colder than normal, and some plants, such as ice plants (Delosperma spp.), considered to be cold-hardy in this climate did not survive through the winter. Irrigation influenced survival for the summer period and only succulent plants like stonecrops (Sedum spp.) survived without irrigation. Irrigated experimental green roofs had significantly lower summer substrate temperatures (up to 20 °F lower) and plants survived in irrigated conditions. Plants that survived both winter and summer under irrigated conditions include pussytoes (Antennaria plantaginifolia), mouse-ear tickseed (Coreopsis auriculata), eastern bottlebrush grass (Elymus hystrix), glade cleft phlox (Phlox bifida stellaria), and eggleston's violet (Viola egglestonii). Irrigation is recommended on extensive green roofs to increase the palette for plant selection by protecting against plant mortality due to drought and extreme soil temperatures.

Antimonopoly, meaning opposition to the exclusive or near-exclusive control of an industry or business by one or a very few businesses, played a relatively muted role in the history of the post-1945 era, certainly compared to some earlier periods in American history. However, the subject of antimonopoly is important because it sheds light on changing attitudes toward concentrated power, corporations, and the federal government in the United States after World War II. Paradoxically, as antimonopoly declined as a grass-roots force in American politics, the technical, expert-driven field of antitrust enjoyed a golden age. From the 1940s to the 1960s, antitrust operated on principles that were broadly in line with those that inspired its creation in the late 19th and early 20th century, acknowledging the special contribution small-business owners made to US democratic culture. In these years, antimonopoly remained sufficiently potent as a political force to sustain the careers of national-level politicians such as congressmen Wright Patman and Estes Kefauver and to inform the opinions of Supreme Court justices such as Hugo Black and William O. Douglas. Antimonopoly and consumer politics overlapped in this period. From the mid-1960s onward, Ralph Nader repeatedly tapped antimonopoly ideas in his writings and consumer activism, skillfully exploiting popular anxieties about concentrated economic power. At the same time, as part of the United States’ rise to global hegemony, officials in the federal government’s Antitrust Division exported antitrust overseas, building it into the political, economic, and legal architecture of the postwar world. Beginning in the 1940s, conservative lawyers and economists launched a counterattack against the conception of antitrust elaborated in the progressive era. By making consumer welfare—understood in terms of low prices and market efficiency—the determining factor in antitrust cases, they made a major intellectual and political contribution to the rightward thrust of US politics in the 1970s and 1980s. Robert Bork’s The Antitrust Paradox, published in 1978, popularized and signaled the ascendency of this new approach. In the 1980s and 1990s antimonopoly drifted to the margin of political debate. Fear of big government now loomed larger in US politics than the specter of monopoly or of corporate domination. In the late 20th century, Americans, more often than not, directed their antipathy toward concentrated power in its public, rather than its private, forms. This fundamental shift in the political landscape accounts in large part for the overall decline of antimonopoly—a venerable American political tradition—in the period 1945 to 2000.
