Ano: 2009 URL: http://purl.umn.edu/60678 Vertical Channel Analysis of the U.S. Milk Market AgEcon Hovhannisyan, Vardges; Stiegert, Kyle W.. The objective of the research in this study is to evaluate the pricing and market conduct of milk manufacturers and retailers. Using data from a U.S. Midwestern state, we estimate a random coefficient logit demand model (RCL) to empirically investigate a range of possible scenarios in the milk supply chain. These include vertical leader-follower model with underlying Bertrand-Nash pricing, models allowing for nonlinear pricing contracts, and collusion scenarios at various levels in the supply chain. This study contributes to the literature in the following ways. First, it generalizes the RCL demand model via Box-Cox power transformation. While previous studies rely on ad hoc specified linear indirect utility, this procedure allows data to determine the...

Ano: 2011 URL: http://purl.umn.edu/103631 ARMENIAN RURAL COOPERATIVES AND MARKETING: DAIRY SECTOR AgEcon Hovhannisyan, Vardges; Vasa, Laszlo. Armenian milk marketing cooperatives provide several benefits, of which the increased opportunity for milk marketing is valued most by member farmers. During the cooperative action milk production has also increased due to seminars on cattle feeding, artificial insemination, sanitation programs, and support by cooperatives in feed procurement. Another benefit is that through pooling products of specified grade or quality, marketing cooperatives are better able to market milk to large-scale buyers than individual owners. Putting their efforts together cooperatives can move to distant markets and thus expand their sales opportunities. This is of paramount importance for those cooperatives that have a sole buyer. In addition to milk marketing, almost all of...

Ano: 2007 URL: http://purl.umn.edu/58902 Quantifying the Structure of Food Demand in China Using a Generalized Quadratic AIDS Specification AgEcon Hovhannisyan, Vardges; Gould, Brian W.. This manuscript is used to examine food demand structure and its dynamics for 11 commodities in urban China. The analysis is based on household-level expenditure survey data for two cross-sectional surveys of Chinese households pertaining to food expenditure patterns during 1995 and 2003. A major focus of this presentation is on the pre-committed component of demand that is not accounted for by economic and demographic characteristics. We use the generalized quadratic almost ideal demand system (GQAIDS) for its empirical superiority to the GAIDS, and estimate the associated parameters via a full information maximum likelihood procedure (FIML) procedure, where we test for whether total food expenditure for home consumption (FAH) is endogenous. We also use...

Ano: 2010 URL: http://purl.umn.edu/56422 The Role of Specialized Agricultural Credit Institutions in the Development of the Rural Finance Sector: Case of Credit Clubs in Armenia AgEcon Aleksandryan, Mariana; Urutyan, Vardan E.; Hovhannisyan, Vardges. The paper aims at studying the challenges of agricultural finance in Armenia. Strengthening the rural credit markets and institutions in Armenia is of paramount importance. The study reviews and analyzes the outcomes of the Agricultural Credit Club Program implemented by the US Department of Agriculture Marketing Assistance Program in Armenia. The study identifies the attitudes and perceptions of member farmers relating to the level of interest rates and access to credit. The findings provided clear indications of the challenges facing the improvement or even development of rural financial markets and agricultural credit institutions from the demand side of agricultural credits. The study concentrates on several important issues like: problems with loan... Tipo: Conference Paper or Presentation Palavras-chave: Agricultural Finance. Ano: 2007 URL: http://purl.umn.edu/9438 Retail Competition in the Milk Market in a U.S. Midwestern City AgEcon Hovhannisyan, Vardges; Gould, Brian W.. The main goal of this manuscript is to explore the retailer conduct in the milk market in a U.S. Midwestern city, based upon a structural estimation of consumer milk demand and retailer optimality conditions. To model milk demand we rely upon the Almost Ideal Demand System, while allowing the retailer optimality conditions to cover a range of competitive scenarios from perfect competition to horizontal cartel. We employ a conjectural variation approach in the spirit of Newly Empirical Industrial Organization to study the competitive environment on the retail landscape. We find that the retail market in question is far from being competitive, with the two major retailers being engaged in an oligopolistic competition. Furthermore, the private label milk...

Ano: 2011 URL: http://purl.umn.edu/99281 Structural Model of Retail Market Power: The U.S. Milk Industry AgEcon Hovhannisyan, Vardges; Gould, Brian W.. The objective of our research is to investigate retailer market conduct in the sale of beverage milk using a structural model of consumer behavior and retailer optimality conditions that embrace a range of competitive scenarios. The study is based on an aggregate level analysis of retailer behavior with milk quantity used as a strategic variable. We contribute to the literature by employing a Generalized Quadratic Almost Ideal Demand System (GQAIDS) to model milk demand. Furthermore, we derive the retailer optimality conditions that incorporate the slopes of inverse GQAIDS demand curves for the products under study. Lastly, we apply this generalized structural model to study the retailer behavior in marketing national brand (NB) and private label (PL)...

Ano: 2006 URL: http://purl.umn.edu/25276 Imperfect Competition between Milk Manufacturers and Retailers in a Midwestern State in the U.S. AgEcon Hovhannisyan, Vardges; Stiegert, Kyle W.. This manuscript studies the market conduct of the milk manufacturers and retail chains in a Midwestern state in the U.S. Following the menu approach we employ a random coefficient logit demand model to investigate several possible scenarios on the supply side. Demand estimates are obtained using both cross-sectional and time series variation in data. We also allow annual variation in consumer demographics which helps identify the coefficients of interaction between consumer demographics and product characteristics. To further enhance identification power we allow choice set of milk to vary across markets. The results are most supportive of the conjecture that manufacturers behave competitively letting the retailers be the residual claimants. Later they...
