Última Relationship Quality and Innovation Capacity of Chains: The Case of the Traditional Food Sector in the EU AgEcon Gellynck, Xavier; Kuhne, Bianka; Weaver, Robert D.. The purpose of the paper is to explore how the perceived relationship quality is related to the innovation capacity in chains of the traditional food sector. Based on suggestions from theory and previous studies, empirical evidence is drawn from a survey of 90 traditional food chains including 270 chain partners from three European countries in four traditional food product categories. Heterogeneity across these chains is first examined based on cluster analysis that identifies three distinct clusters interpreted as reflecting three levels of intensity in innovation capacity: high, medium, and low. Next, we define measures of the chain relationship quality through characteristics such as trust, conflict and reputation. Results suggest that various aspects...

AgEcon Weaver, Robert D.; Chin, Ming-Chin. This paper reconsiders the impacts of generic advertising on commodity prices that may be induced through demand effects. Rather than considering a simple demand shift, we consider the possibility that advertising leads to a change in the curvature of the demand curve. In this case, generic advertising is shown to affect both the level of market prices as well as their volatility. Based on parametric tests, we find that the demand elasticity appears to be affected by the intensity of generic advertising. In addition, we find evidence that generic advertising affects the curvature of the demand curve. We examine the implications of these findings for the price of beef. Our results are consistent with the hypothesis that generic advertising enhances... Tipo: Conference Paper or Presentation Palavras-chave: Marketing.

As national economies have integrated through removal of trade barriers, the potential for offshoring production was quickly recognized as a strategy to enhance firm performance. At the same time, labor market reforms opened the door for outsourcing of labor services to specialist firms that supply labor force teams. The implications of these trends for industries that rely on specialized workforces have drawn considerable attention. Both manufacturing and food processing have seen substantial movement toward oursourced labor, yet little research has considered the implications of these trends. In both manufacturing and food processing, specific labor skills are needed that require training and consistency of supply to ensure efficiency in raw material and...

Ano: 2009 URL: http://purl.umn.edu/59201 MARKET STRUCTURE AND THE DYNAMICS OF RETAIL FOOD PRICES AgEcon Weaver, Robert D.; Chattin, Peter; Banerjee, Aniruddha. The effect of retail grocery market structure on the speed of adjustment of retail food prices to changes in producer prices, real wages, and the cost of energy was examined for SMSAs. Evidence failed to support the implication of the Mason-Bain paradigm that increased concentration reduces market efficiency as reflected in speed of retail price adjustment. Evidence of strong intertemporal relationships between change in producer prices and retail prices found for the categories meat, poultry, fish, eggs and cereal and baker products provide support to the hypothesis of cost-push inflation.

This paper presents a dynamic theory of structural change in which functional change driven by technological change and transactional change open opportunity for change in scale and scope of enterprises. Implementation of change in scale and scope of enterprises is constrained by initial state conditions including resource endowments, access to credit, and regulation. In the presence of such constraints, the paper motivates the existence of thresholds that introduce cusps in the optimal paths of control variables. The evolution of enterprises is considered within the context of a multiple enterprise firm that encompasses discrete and continuous processes that are interdependent on intermediate goods as well as their production of environmental effects....

Ano: 1989 URL: http://purl.umn.edu/28861 TARGETING ENVIRONMENTAL PROTECTION IN AGRICULTURE: IPM AND BMPS AS ENVIRONMENTAL PERFORMANCE INDICATORS AgEcon Weaver, Robert D.; Kim, Taeho. Nonparametric technical efficiency estimates of potentially polluting input use in soybean and wheat indicate substantial heterogeneity across farms. This implies large costs would be associated with uniform standards or incentives to regulate these inputs. While technical efficiency is not observable, indicators of environmentally beneficial practices are found useful predictors.

Ano: 1999 URL: http://purl.umn.edu/21576 Contracting, Signaling of Uncertain Quality, and Price Volatility? AgEcon Chin, Ming-Chin; Weaver, Robert D.. Theoretical and simulation results clarify the role of forward procurement contracting as a determinant of spot price levels and volatility. A stylized model determines market share across quality when procurers forward contract to manage quality risk. Actual supply is specified as price dependent and stochastic. Simulation examines sensitivity of spot price level and volatility to extent of forward contracting, risk aversion, and ability to adjust spot market demand (recontracting). The results show that as forward contracting increases mean spot price decreases and variance increases. This effect increases as risk aversion decreases and as the extent of recontracting adjustment in spot demand decreases. Tipo: Conference Paper or Presentation Palavras-chave: Risk and Uncertainty. Ano: 2002 URL: http://purl.umn.edu/24790 PRIVATE LABELS: A MECHANISM FOR FULFILLING CONSUMER DEMAND FOR HEALTHY FOOD? AgEcon Weaver, Robert D.; Moon, Yongma. As consumer preferences rapidly evolve with respect to health-related attributes of food, many have questioned the performance of the conventional food industry to fulfill new demand. As the structure of the industry has shifted toward conditions where retailers have access to and incentive to respond to rapidly changing information concerning consumer preferences, it is relevant to consider the conditions under which retailers will offer private labeled healthy food products not available from national brand manufacturers. This paper presents a theory of the dynamic, stochastic decision of retailers to offer private label products that are close substitutes to national brands. Within the context of salient features of healthy foods, we examine the role of...

Ano: 2010 URL: http://purl.umn.edu/116397 Designing Crop Insurance to Manage Moral Hazard Costs AgEcon Weaver, Robert D.; Kim, Taeho. A new crop insurance model based on just random risk (natural states) is presented instead of traditional model based on random risk, guaranteed price, and guaranteed yield. The simulation approach shows how the incentive compatibility constraints resolve the moral hazard problem by the insured under the insurer-agency crop insurance contracting.

Ano: 2002 URL: http://purl.umn.edu/19052 Pricing Perishables AgEcon Weaver, Robert D.; Moon, Yongma. A key feature of food products is their perishability. Within the short marketing window that characterizes most food and ag products, demand is typically highly stochastic and difficult to predict. This combination of features poses substantial challenges to retailers when pricing products and has implications for performance that ripples through vertical food chains. For many food products, processing to forms that can be preserved and held in inventory has traditionally been used as a means of coping with these conditions, despite its high costs and ancillary risks introduced such as change in product attributes and deterioration. This paper presents an alternative ERM strategy that focuses on dynamic pricing to control the rate of sale for perishable...

Ano: 2011 URL: http://purl.umn.edu/122007 Supply Chain and Network Performance: Metrics for Profitability, Productivity, and Efficiency AgEcon Weaver, Robert D.. The architecture of the firm involves determination of a boundary that encompasses the functions managed by the firm. The past decade has seen substantial reorganization of firms where vertical or horizontal integration has been unbundled into weaker forms of collaborations including value chains and networks. This observation has forced a re‐conceptualization of the boundaries of the firm to incorporate such collaborations. These collaborations are virtual and highly dynamic. They emerge and persist when two conditions are met. First, they must enable generation of greater value than might be attained through independent operation and anonymous transactions through markets. Second, the resulting growth must be shared with members in a way that retains...

Ano: 2010 URL: http://purl.umn.edu/91142 Private Labels: A Sign of Changing Times AgEcon Haas, Rainer; Weaver, Robert D.. A widely held view is that a dramatic shift is well underway in the structure of food system. First noticed at the farm level, contracting between retailers and fruit and vegetable growers for specific quality attributes signaled a shift from commodity style markets to relational transactions managed by retail grocers operating on massive spatial scales. By contracting directly with suppliers, retailers found they could more efficiently procure and manage characteristics of products and transactions that affect their performance. Similar contracting between meat processors and growers emerged in animal production. As a result of this shift, retailers define product specifications and contract their production. This new organizational form constitutes a...

Ano: 2010 URL: http://purl.umn.edu/100586 Structural Change in Transition: A Role for Organizational Legitimacy? Evidence from Czech Agriculture AgEcon Curtiss, Jarmila; Brümmer, Bernhard; Medonos, Tomas; Weaver, Robert D.. Market liberalization in Central and Eastern Europe was targeted at establishing incentives that would improve economic performance. While substantial reorganization of enterprises is observed, firms can also be observed which devote resources towards establishing organizational legitimacy. Motivations for such behavior are considered and empirical evidence of its relationship with technical efficiency using a distance function approach is analyzed for the case of Czech agriculture. Contrary to the expectation that such behavior would be inefficient, we find that firms reap private economic gains from legitimacy efforts through improved access to agricultural land, investment subsidies and firm internal social capital. However, its effect on technical...

Ano: 2005 URL: http://purl.umn.edu/24557 PRICE VOLATILITY IN THE U.S. DAIRY SECTOR: DUE TO WEEK-OF-MONTHS EFFECTS? AgEcon Natcher, William C.; Weaver, Robert D.. Under recent dairy policy reforms, farm-level milk prices are determined by a multiple component pricing scheme that derives monthly dairy product class prices from weekly NASS survey prices for only the first two weeks of each month. This pricing rule may provide incentives for strategic behavior by dairy sector participants that could induce dairy product price volatility. This paper employs a series of nonparametric approaches to examine evidence of such price manipulation in CME weekly average dairy product prices. Empirical evidence suggests that no such week-of-month effects exist in levels of prices, and only very weak evidence of week-of-month effects in price volatility was found. Together, results suggest dairy product markets are... Tipo: Conference Paper or Presentation Palavras-chave: Marketing. Ano: 2001 URL: http://purl.umn.edu/20551 Network connections and innovation capacity in traditional agrifood chains AgEcon Kuhne, Bianka; Gellynck, Xavier; Weaver, Robert D.. In the New Economy, the network is considered as more important than the firm itself. In this paper the focus is on chain networks which include vertical networks among chain members, horizontal networks with peers, and networking with third parties. Networks have an important role in the diffusion and adoption of innovations, thus they are the locus of innovation. While previous research focused on the firm, we contribute to the understanding of innovations in chain networks, i.e. we investigate the innovation capacity in vertical networks and how networking with peers and third parties is influencing the innovation capacity of the vertical network. We propose that there is a positive relationship between the network connections the direct chain partners...
