Perspectives on the Management of Surplus Dairy Calves in the United States and Canada.

Front Vet Sci 2021 13;8:661453. Epub 2021 Apr 13.

Department of Population Medicine, University of Guelph, Guelph, ON, Canada.

The care of surplus dairy calves is a significant issue for the United States and Canadian dairy industries. Surplus dairy calves commonly experience poor welfare as evidenced by high levels of mortality and morbidity, and negative affective states resulting from limited opportunities to express natural behaviors. Many of these challenges are a result of a disaggregated production system, beginning with calf management at the dairy farm of origin and ending at a calf-raising facility, with some calves experiencing long-distance transportation and commingling at auction markets or assembly yards in the interim.

Factors affecting dairy calf price in auction markets in Québec, Canada: 2008-2019.

J Dairy Sci 2021 Apr 19;104(4):4635-4649. Epub 2021 Feb 19.

Faculté de médecine vétérinaire, Université de Montréal, 3200 rue Sicotte, St-Hyacinthe, QC, J2S 2M2, Canada.

Dairy calves not kept for replacement are sold at young age in Québec auction markets for white and grain-fed veal calf production. The province of Québec produces 80% of the Canadian veal meat, but little information is available on the factors associated with the calves' price per crude weight (Can$/kg; Can$1 = US$0.78 at time of writing).

The effect of life history events on carcass merit and price of cull dairy cows.

J Anim Sci 2021 Jan;99(1)

Department of Animal and Dairy Sciences, University of Wisconsin-Madison, Madison, WI.

Cull dairy cows contribute almost 10% of national beef production in the United States. However, different factors throughout the life of dairy cows affect their weight and overall body condition as well as carcass traits, and consequently affect their market price. Therefore, the objectives of this study were: (1) to assess relationships between price ratio and carcass merit of cull dairy cows sold through several sites of an auction market and (2) to investigate the effect of animal life history events and live weight on sale barn price (BP) and price ratio (as a measure of relative price), as an indicator of carcass merit.

Confronting genetic gains with markets: Retrospective lessons from New Rice for Africa (NERICA) in Uganda.

Outlook Agric 2020 Dec 20;49(4):298-310. Epub 2020 Aug 20.

International Rice Research Institute (IRRI), Los Baños, Philippines; Formerly at Africa Rice Center (AfricaRice), Saint-Louis, Senegal.

Breeders have two non-exclusive strategic investment options for increasing smallholder farmers' and consumers' livelihoods through genetic improvement of crop varieties: (i) enhancing productivity; and (ii) enhancing value and market access. New Rice for Africa (NERICA) varieties with superior agronomic characteristics were bred and introduced in various African countries in the early 2000s. Two decades later, drought tolerant NERICA4 is among the popular upland rice varieties grown across Africa. Read More

Aggregation mechanisms for crowd predictions.

Exp Econ 2020 9;23(3):788-814. Epub 2019 Nov 9.

Department of Banking and Finance, University of Innsbruck, Universitätsstraße 15, 6020 Innsbruck, Austria.

When the information of many individuals is pooled, the resulting aggregate often is a good predictor of unknown quantities or facts. This aggregate predictor frequently outperforms the forecasts of experts or even the best individual forecast included in the aggregation process ("wisdom of crowds"). However, an appropriate aggregation mechanism is considered crucial to reaping the benefits of a "wise crowd". Read More

Art markets in crisis: how personal bonds and market subcultures mediate the effects of COVID-19.

Am J Cult Sociol 2020 Oct 7:1-15. Epub 2020 Oct 7.

Department of Sociology, University of California, Santa Barbara, CA 93106 USA.

We examine how the contemporary art market has changed as a result of the disruptions caused by the novel coronavirus. Based on interviews with artists, collectors, a dealer, and an auction house executive, we argue that the decline of face-to-face interaction, previously essential to art market transactions, has placed strain on each corner of the community. In the absence of physical co-presence with the artworks and art world actors, participants struggle to evaluate and appreciate artworks, make new social ties, develop trust, and experience a shared sense of pleasure and collective effervescence.

Behavior and Health Indicators to Assess Cull Cow's Welfare in Livestock Markets.

Front Vet Sci 2020 7;7:471. Epub 2020 Aug 7.

Instituto de Ciencia Animal, Facultad de Ciencias Veterinarias, OIE Collaborating Centre for Animal Welfare and Livestock Production Systems-Chile, Universidad Austral de Chile, Valdivia, Chile.

The welfare status of cull cows going through livestock markets was assessed in 12 premises in Chile, using behavioral and health indicators observed during unloading, auction, and loading (once in winter and once in summer). Groups of cows were observed by the same observer and the following indicators were recorded at each stage: slips, falls, balks, turns, jumps, and vocalizations of cows were considered as behavioral events and a proportion was calculated based on the number of observed events per group divided by the number of cows per group to give a behavioral event index (BEI). Health status of the cows was assessed during auction by recording the proportion of cows with low body condition, lameness, udder problems, tegumentary lesions, and tail abnormalities. Read More

Short communication: Condition of male dairy calves at auction markets.

J Dairy Sci 2020 Sep 16;103(9):8530-8534. Epub 2020 Jul 16.

Animal Welfare Program, University of British Columbia, Vancouver, British Columbia V6T 1ZA, Canada.

Male dairy calves in North America are frequently marketed through live auctions. Calves have been observed in suboptimal condition both at auctions and upon arrival at calf-rearing facilities that supply the veal or dairy-beef industries. The objectives of this study were to describe the health of male dairy calves at a commercial auction in British Columbia, Canada, examine the relationships between calf price and condition, and use price data from other auctions to reflect more broadly on the variability in calf condition at auction markets.

Experimental and survey-based data on willingness to pay for seafood safety and environmental sustainability certification in Nigeria.

Data Brief 2020 Jun 14;30:105540. Epub 2020 Apr 14.

WorldFish, Jalan Batu Maung, Batu Maung 119, Penang Malaysia.

Aquatic foods, including fish, are a substantial component of animal source foods globally, and make a critical nutritional contribution to diets in many contexts. In the global North, concern among consumers and regulators over the safety and environmental sustainability of seafood, particularly in developed nations, has led to the development of increasingly stringent seafood safety standards. While such standards may constitute regularity, logistical, and economic barriers to participation in export markets by small-scale producers, they have in other contexts catalysed upgrades to production and post-harvest handling practices within value chains associated with both capture fisheries and aquaculture.

Liquidity backstops and dynamic debt runs.

J Econ Dyn Control 2020 Jul 27;116:103916. Epub 2020 Apr 27.

Emory University, Federal Reserve Bank of Atlanta, and NBER, United States.

Liquidity backstops can mitigate runs. In this paper we develop a dynamic model of debt runs based on He and Xiong (2012) to identify, both conceptually and quantitatively, the value of a liquidity backstop for its run-mitigating role. For the purpose of identification, we focus on the municipal bond markets for variable rate demand obligations and auction rate securities. Read More

Management of cull dairy cows: Culling decisions, duration of transport, and effect on cow condition.

J Dairy Sci 2020 Mar 15;103(3):2636-2649. Epub 2020 Jan 15.

Animal Welfare Program, Faculty of Land and Food Systems, The University of British Columbia, Vancouver, V6T 1Z4, Canada.

Many cows culled from dairy farms arrive at livestock markets or abattoirs in compromised condition, but it is unknown whether cows are compromised at the time of culling or deteriorate during the marketing process. This study followed cull cows from farm to abattoir, monitored any deterioration, and tested the effect of providing such information on subsequent culling. For 11 mo, data were collected from 20 dairy farms, livestock markets, and abattoirs. Read More

Fitness for transport of cull dairy cows at livestock markets.

J Dairy Sci 2020 Mar 25;103(3):2650-2661. Epub 2019 Dec 25.

Animal Welfare Program, Faculty of Land and Food Systems, The University of British Columbia, 2357 Main Mall, Vancouver, BC, V6T 1Z4, Canada.

Cows are regularly removed from dairy herds and sold at livestock markets. Many cows are removed because of health problems, and their fitness for transport may vary because of seasonal variation, delayed or poor on-farm culling decisions, injuries during transport, and other factors. However, many dairy producers lack feedback about the condition of their cows during the marketing process and how cow condition influences sale price. Read More

The effect of competition on discrimination in online markets-Anonymity and selection.

PLoS One 2019 28;14(8):e0221857. Epub 2019 Aug 28.

Independent Researcher, Stockholm Internet Research Group, Stockhlm, Sweden.

Empirical studies show that discrimination by identity found in offline markets also prevails online. This paper reveal that in a competitive market, buyers that intend to discriminate exist but they are prevented from influencing the market outcome. To this end, we construct a field experiment on eBay, where half of the sellers disclose their names in their usernames while the other half do not. Read More

More landings for higher profit? Inverse demand analysis of the bluefin tuna auction price in Japan and economic incentives in global bluefin tuna fisheries management.

PLoS One 2019 23;14(8):e0221147. Epub 2019 Aug 23.

Institute of Applied Economics, National Taiwan Ocean University, Keelung, Taiwan, Republic of China.

This paper estimates the price changes in global bluefin tuna (BFT) markets in response to shifts in regional and global landings to evaluate the conservation and economic incentives from changes in the Total Allowable Catch (TAC) managed by all three Regional Fisheries Management Organizations. A fisherman's income, and thus the financial incentive to accept management measures controlling catch levels, depends in part on how responsive price is to overall catch. Individual fisherman, with their own best interest in mind, used to wish to increase their individual landings and create an incentive to ask to increase the TAC for the industry, without realizing the possible revenue loss due to the resulting falling prices.

Department of Network and Data Science, Central European University, H-1051, Budapest, Hungary.

Competing firms can increase profits by setting prices collectively, imposing significant costs on consumers. Such groups of firms are known as cartels and because this behavior is illegal, their operations are secretive and difficult to detect. Cartels feel a significant internal obstacle: members feel short-run incentives to cheat. Read More

Associations between the general condition of culled dairy cows and selling price at Ontario auction markets.

J Dairy Sci 2018 Nov 7;101(11):10580-10588. Epub 2018 Sep 7.

Department of Population Medicine, University of Guelph, Guelph, ON, N1G 2W1, Canada; Campbell Centre for the Study of Animal Welfare, University of Guelph, Guelph, ON, N1G 2W1, Canada. Electronic address:

Dairy cows are culled from the herd for a variety of reasons, the most common being fertility problems, low milk production, or udder problems. Disease and injury can contribute to the decision to cull either directly, or indirectly, by causing fertility or production problems, leading to culling. Disease or injury may also affect the cow's ability to handle the stress of transportation and may increase the risk for reduced welfare. Read More

Department of Mathematics, King's College London, Strand, London, WC2R 2LS, United Kingdom.

We study the distribution of strategies in a large game that models how agents choose among different double auction markets. We classify the possible mean field Nash equilibria, which include potentially segregated states where an agent population can split into subpopulations adopting different strategies. As the game is aggregative, the actual equilibrium strategy distributions remain undetermined, however. Read More

Trust or robustness? An ecological approach to the study of auction and bilateral markets.

PLoS One 2018 7;13(5):e0196206. Epub 2018 May 7.

CRED- TEPP, Université Panthéon-Assas Paris II, Paris, France.

Centralized markets are often considered more efficient than bilateral exchanges because information is public and the same for all the agents. On decentralized markets, where the information is private, the influence of trust on the market outcome has been underlined by many authors. We present an empirical study of the distinctive Boulogne-sur-Mer Fish Market (where both buyers and sellers can choose to trade by either bidding or bargaining), focused on the interactions between agents.
