The Collusion-deterring Effect of Pre-attributed Supplies and the Hog Auction in Quebec

The hog/pork industry in Quebec has been going through major institutional changes since 1989, the year an electronic auction was put in place to market all of the hogs in the province. Because the auction's ability to generate high prices did not meet the expectations of hog producers, the pure auction system was replaced by a hybrid one in 1994. In this system, most of the hog supply was pre-attributed to processors at a negotiated price based on the US. price while the remainder of the provincial supply of hogs was sold through the auction. In this paper, we investigate how a seemingly inefficient marketing mechanism like pre-attributions can increase the efficiency of a usually efficient mechanism like an auction. We present theoretical arguments regarding the sustainability of collusion under the pure auction and hybrid systems in addition to analyzing auction prices with modern time series tools.     

Regional Impacts of a U.S. Hog Slaughter Plant Closing: The Thorn Apple Valley Case

As the 1998 U.S. hog market collapse unfolded, Thorn Apple Valley ceased hog slaughter operations at its Detroit, Michigan plant. We examine the impacts on Michigan live hog prices relative to Eastern Corn Belt hog prices. Results indicate that Michigan producers' relative price advantage diminished after the closure as procurement competition changed. As the impacts of the 1998 hog market collapse were absorbed, Michigan producers' relative price advantage became consistently negative. Examination of Michigan's market hog production distribution indicates postclosure shifts away from production in areas geographically near to Thorn Apple Valley and growth in counties geographically closer to alternative packers.     

A SIMULATED STUDY OF AN AUCTION MARKET

A simulated model of an auction market is developed showing the relationship between the variation in valuations, the price variation and the number of independent bidders in the market. Average prices paid in a market with two or three bidders are less than average valuations. Average prices are progressively greater than average valuations as the number of bidders increases beyond four. Some applications of this model in the Australian wool market are discussed.     

Testing for Processor Market Power in the Markets for Cattle and Hogs in Canada

Deviations of livestock input prices from processor marginal value product are usually interpreted as an indication of the application of market power by the meat packing industry. However, market power depends on economic conditions that can influence the behavior of meat packers in the market for cattle and hogs. An industry-level translog profit function is applied to data on the Canadian finished cattle and hog markets and industry-wide oligopsony market power functions are estimated. The estimates suggest beef packers exercised a small but sustained amount of market power in the Canadian finished cattle market from 1978 to 1997. This is not the case in the market for hogs, which was competitive from 1960 to 1997. Application of market power in packers'purchases of farm animals decreased with increases in the utilization of domestic supply of slaughter animals and with increased levels of livestock exports. Livestock productivity increases appear to have significantly enhanced oligopsony power in packers'purchases of farm animals. The analysis suggests that beef processors may exert market power when cattle prices are relatively higher.     

Auction markets for specialty food products with geographical indications

We present a first analysis of online auction markets for specialty food products. We identify auction prices, trade volume, and value for domestic and foreign-origin specialty ham with geographical indications (GIs) that were sold in online auctions in Germany within a 1-month period. Applying hedonic modeling, we examine potential factors that may influence online bidding behavior and final auction prices. We estimate positive auction price effects for weight, bidding activity, and auction length, that the domestic product is sold at a discount, that higher shipping costs have a negative impact on final prices, and that auctions ending on Fridays and Saturdays yield lower prices. The model may be used to estimate the value of GIs. In our example, we estimate relative price differences of 20–30% for the GIs of three specialty hams (Prosciutto di Parma, Jamón Serrano, and Schwarzwälder Schinken).     

The impact of auction characteristics on prices of agricultural products traded online: evidence from cherries

This article provides an empirical study on the relationship between auction characteristics and prices using a data set on cherry sales from the online auction site Yahoo! Kimo. Using three alternative measures of the dependent variable, results indicate that reputation variables have a statistically important association with auction prices. The extent of reputation's impact on prices varies substantially depending on the model specification and estimation technique. The article highlights the effectiveness of a nonlinear specification for both measuring and interpreting the underlying reputation variables. The use of a “Buy It Now” option, size, and country of the origin is correlated with prices at statistically significant levels. Several econometric concerns regarding the empirical modeling strategy are discussed.

How well do conservation auctions perform in achieving landscape‐level outcomes? A comparison of auction formats and bid selection criteria

This paper studies the performance of auction design features regarding pricing mechanisms and bid selection criteria for securing wildlife zones across different holdings. We compare two pricing mechanisms: a discriminatory‐price auction and a uniform‐price ascending auction, and four bid selection criteria on the basis of: total bid, bid‐per‐value ratio, bid‐per‐area ratio and a mixed criterion where bids are formed on the basis of cost but they are selected based on the bid‐per‐value ratio. We develop a best‐response group‐bidding model for a discriminatory‐price auction where bidders form optimal group bids for individual wildlife zones. In the uniform‐price ascending auction, individual landholders respond to prices, which are successively raised by the auctioneer and whenever all the landholders from a single zone agree to participate (i.e. the first zone is formed), the auction stops. Based on numerical simulations using a bio‐economic model of malleefowl conservation, we observe that the discriminatory‐price auction is more cost‐effective than the uniform‐price ascending auction. However, the budgetary cost‐effectiveness of a discriminatory‐price auction is sensitive to bidder uncertainty about the number of competing bidder groups and the highest cost of establishing a wildlife zone among these groups. In terms of bid selection, the mixed bid selection criterion performs best. We discuss the policy implications of these findings.     

How Reliable Are Hog Futures as Forecasts?

The Chicago Mercantile Exchange hog futures contract was revamped in 1997 and it is one of the largest futures markets for a nonstorable commodity. The literature is divided on whether or not futures prices for nonstorables provide reliable forecasts of cash prices. We find that from 1998 to 2004, the hog futures market was an unbiased predictor of cash prices.     

Could packers manipulate spot markets by tying contracts to futures prices? And do they?

Some producers, policy makers, and researchers claim that packers influence cash prices through contracts tied to futures prices. This paper provides a theoretical and empirical study on the price effects of contract-pricing terms linked to futures price and the related formula pricing terms linked to a cash price. We show that contract-pricing terms tied to a cattle futures price can theoretically be used to reduce the cash price. Furthermore, the model demonstrates that such tied-to-a-futures-price contract-pricing clauses and the related tied-to-a-cash-price formula pricing clauses can be substitutable tools for packers to depress the cash cattle price. Nevertheless, although empirical results are consistent with the predictions of the theoretical model they show that while such manipulations may occur, their market power impact appears quite small.     

Does It Pay to Increase Competition in Combinatorial Conservation Auctions?

Conservation auctions allow landholders to propose conservation projects and associated payments (bids) for consideration by a conservation agency. Recently, the application of iterative combinatorial auction designs has been proposed to improve outcomes of conservation auctions. In combinatorial auctions, landholders are allowed to offer projects each of which involves activities aimed at providing one or multiple services. An iterative format allows bidders the opportunity to gradually explore the type of projects they want to offer, with this process being facilitated through price feedback provided based on intermediate auction round results. Auction designs vary with the type of feedback and respond differently to market conditions. At present there is a lack of information about their performance in markets with varying degrees of competition (in terms of number of bidders and level of target). Therefore, using an agent‐based simulation model, we evaluate a number of iterative auction designs. We observe that a higher degree of competition leads to a higher auction efficiency. In a high competition environment, efficiency outcomes tend to be less sensitive to auction design choices. Therefore, an auctioneer could enjoy freedom in design choice if adequate competition could be ensured. In weak competition environments, however, some auction designs perform better than others.     

Is Exchange Rate Pass-Through in Pork Meat Export Prices Constrained by the Supply of Live Hogs?

The impact of lags in the production and marketing of agricultural products on the degree of exchange rate pass-through in export prices is investigated. The predictions of the theoretical model are tested by investigating Canadian pork export prices in the United States and Japan. The empirical methodology accounts for unit root and cointegration using the dynamic seemingly unrelated regression framework and a minimum distance estimator. Predetermined hog supplies have a statistically significant impact on export prices of two out of three Canadian provinces. The degree of misspecification involved with standard pass-through models that do not account for production lags is also illustrated.     

The declining price anomaly in sequential auctions of identical commodities with asymmetric bidders: empirical evidence from the Nephrops norvegicus market in France

The declining price anomaly for sequential sales of identical commodities challenges auction theory which predicts constant prices within a day. Among other hypotheses explaining the phenomenon stands the dual value of goods including a risk premium in early transactions. We consider that asymmetric bidder groups (primary processors, fishmongers, supermarket buyers) and seasonal landings may also affect the daily price pattern. On the basis of stylized facts and several panel data models, this hypothesis is tested on a Redundant French fish market of homogenous goods (live Nephrops norvegicus) when the time effects (high and low seasons, weekday effect) affecting the demand and supply conditions are taken into consideration. All models support the evidence of a daily declining pattern, but not to the same extent for all days and seasons, and all categories of buyers. Our results also show an earlier and steeper decline on periods of lower supply (or higher demand), supporting the theoretical hypothesis of risk‐averse behaviors of bidders, especially fishmongers with respect to primary processors and supermarkets.     

Negative Values in Vickrey Auctions

Some people assign negative values for new products sold on laboratory auction blocks (i.e., irradiated meat). We explore bidding behavior in two Vickrey auctions when people have positive- and negative-induced values for the good. Aggregate bidding in the second-price auction is precise but biased—highest-value positive bidders tend to overstate benefits, whereas lowest-negative bidders understate losses. In contrast, bidding behavior in the random n th-price auction is demand revealing irrespective of induced value, but it is imprecise. Examining on- and off-margin bidding behavior, we cannot conclude that any segments of demand are significantly different than the demand revealing regression line.     

Developing Economic Indexes for the Quebec Hog/Pork Industry

The Quebec hog/pork industry has grown significantly over the last 25 years. Explanations of this growth in the literature have centered on government policies, expansion of profitable market opportunities, and reforms in marketing institutions. A coincident index model that trends with total hog slaughters in Quebec is estimated using a dynamic factor model. It implicitly defines a variable that measures the overall state of economic activity in the Quebec hog/pork industry. The results show that reforms in hog marketing institutions are strongly correlated with the economic expansion of the industry. A leading economic index also forecasts the growth of the coincident index using leading variables. The overall statistical performance of the leading coincident index is disappointing, but the growth in American inventories of frozen pork meat is shown to have useful predictive value.     

On the nature and magnitude of cost economies in hog production

In this article, we assess the impact of farm size on production cost and evaluate the marginal costs and margins by considering that input prices may change with the scale of production. By using French hog farm data, we estimate a system of equations including a feed price function, input demand functions, and an output supply function based on a technology approximated by a combined generalized Leontief‐Quadratic form. Our results suggest that the marginal costs are over‐estimated when the adjustment of the feed unit prices to a change in farm size is not controlled for. More specifically, the cost economies for large farms (enjoying the highest profits) arise primarily from lower feed prices, with technological scale economies having little impact. In contrast, farms with no hired labor exhibit technological scale economies and reach higher price‐cost margins compared to larger farms.     

Risk Preferences of Dairy and Hog Producer in Quebec

The objective of this study is to investigate the nature of risk preferences of Quebec dairy and hog producers. The direct elicitation of utility method is employed to determine producers'degree of risk aversion. The Delphi process is used to obtain more refined and realistic responses. The results reveal that the risk preferences of the randomly selected Quebec farmers are highly diverse. The percentage of risk-taking farmers ranges from 8% to 23% depending upon the level of investment and the nature of the enterprise. On average, the majority of farmers in both groups are found to be risk averse. Based on the differences between the means as well as distributions, although not significant in all cases, hog producers are found to be consistently more risk averse than dairy producers. Moreover, the gap between the two groups widens as the level of investment increases. The implications of this result are that the stability of farm income due to supply management in dairy sector may facilitate investments of a given risk (for example, adoption of a new technology) more so than it would in the hog sector.     

Bidding for Cattle in the Texas Panhandle

Four beef-processing plants in the Texas Panhandle region procure cattle from feedlots in a form of first-price, sealed-bid auction. These auctions have features that distinguish them from standard auctions. Using transactions-level data, we estimated packer bid functions and, via simulations, compared the extant bidding environment to an alternative framework. The simulated auctions on average produced higher seller revenue, more frequent sales to the plant valuing the cattle most highly, and more switching by feedlots among competing packers. We attribute these results to packers' inconsistent bidding on the available lots of cattle and offer alternative explanations for this behavior.     

Prices paid for farmland in Ontario: Does buyer type matter?

In the wake of the substantial increases in farmland values that have occurred in Ontario since 2008, concerns have been expressed regarding the potential influence of nonfarmer buyers, such as investment companies and foreign buyers, on prices paid for farmland. To examine whether these concerns may be warranted, this paper estimates the impact of nonfarmer buyers on sale prices for farmland in Ontario, using a hedonic approach and farmland sales data from 2002 to 2016. Analysis is also conducted to determine whether marginal implicit prices of specific farm attributes differ between farmer buyers and nonfarmer buyers. The results indicate that nonfarmer buyers have paid higher prices for farmland, but only in near‐urban areas. In addition, differences in marginal implicit prices for farmland attributes are found, where farmer buyers value more highly attributes related to the agricultural productivity of the property while nonfarmer buyers value more highly attributes related to nonagricultural use. These results imply that the higher prices paid by nonfarmers may be attributable to the bid‐rent theory, as nonfarmers may be bidding more than farmers for farmland in near‐urban areas due to higher expected returns from future urban use of the land.     

Buyer Collusion and Efficiency of Government Intervention in Wheat Markets in Northern India: An Asymmetric Structural Auctions Analysis

This article uses auction theory to analyze wholesale markets for wheat in Northern India. This approach enables us to characterize the market in terms of buyer asymmetries, to detect the existence of collusion, and to quantify its impact on market prices. We show that buyer asymmetries exacerbate the downward impact of collusion on prices. The article also considers whether the government paid too much for the wheat it procured at the minimum support price, and shows that for our sample it did not. The article is based on a primary survey of two wholesale markets in North India.
