A protectionist foodgrain price policy : The case of rice in Panama

Panama has pursued a protectionist price policy for rice, with domestic prices well above the world market level. The government marketing authority purchases sufficient rice to support the established price level and stores or exports the surplus. Although producers benefit, this policy imposes significant costs on consumers, government expenditures and economic efficiency. One policy recommendation is to bring domestic prices in line with the international level. Although free trade is one possibility, a market stabilization programme could be retained. At a minimum Panama's rice price should reflect domestic demand and not production costs. The unfavourable rice-fertilizer price ratio also deserves attention.     

Will the Market Get it Right? The Placing of New Power Plants in Germany

This paper applies ELMOD, an economic-engineering model of the European electricity market to the issue of optimal investment placing of generation capacity in Germany under different market integration scenarios. The model is formulated as cost minimization approach. We conduct a scenario analysis comparing different rules for power plant placing in a national, a market-coupling and an integrated EU market approach. We find that there are great benefits for consumers and producers if taking into account network conditions and cross border congestion in generation location planning. Moreover a change from national planning to an integrated market planner perspective shows even more improvements in prices and network utilization.     

Dark clouds over the Internet?

Currently, the Internet is characterized by excess capacity, which benefits consumers and producers of Internet-based services alike. High quality and declining prices of interconnection are the basis for many e-commerce, software and equipment businesses. However, tough competition in the Internet backbone market driving these developments could ruin network operators and threaten other markets, too. This paper will pursue the idea of the Internet backbone market's decline based on standard economic theory. The paper will present several scenarios and discuss potential market- and policy-based remedies. It is argued that due to a phenomenon called capacity paradox the industry's future development is overshadowed by “dark clouds”.     

An improved maize marketing system for African countries: the case of Zimbabwe

This article proposes a system for Zimbabwe which retains government control of national stocks and enables the parastatal marketing system to stabilize prices, at the same time ensuring a more rational delivery system in rural areas with prices reflecting storage and transport costs. The local population is encouraged to fulfill local needs, thus avoiding the expense of directing all marketing and processing through the urban areas. A more localized system will also have greater multiplier effects. Zimbabwe's maize marketing system is used to show how this system could be modified with benefits to rural consumers, producers and government. Data suggest there is little market exploitation: price differentials between markts reflect transport costs, returns on storage are reasonable, and voluntary procurement operations are usually able to stabilize prices. Zoning, movement restrictions and compulsory procurement have been shown to destabilize food markets; prices between markets are higher in periods of strict control than when marketing is relatively free. Controlled marketing answers a real political and economic need in Zimbabwe. Existing public food marketing agencies are not inherently inefficient. While stabilizing maize supply, there are important advantages in announcing preplanting prices, but any trade in maize only takes place after price setting. It is unlikely that there would be both imports and exports in any 1 year, except when previous contracts are being fulfilled. 2 policy options are available to cover anticipated periods of insufficient national maize production: the maintenance of a strategic reserve; and importation of maize to cover supply shortfalls. Single-channel marketing should be replaced by an internal free market operating between floor and ceiling prices by supply manipulation to prevent excessive producer and consumer welfare fluctuations. This system would be more efficient and have beneficial effects on development. It is more equitable for the rural poor, and result in greater stability of producer incomes, more reliable food supplies, higher producer prices and the release of public funds.     

Heterogeneous switching costs

We consider a two period model where consumers have different switching costs. Before the market opens an Incumbent sells to all consumers; after the market opens competitors appear. We identify the equilibrium both with Stackelberg and Bertrand competition and show how the presence of low switching cost consumers benefits the Incumbent, despite the fact that it never sells to any of them. Furthermore, we identify a free rider effect among consumers.     

Effects of data localization on digital trade: An agent-based modeling approach

Post the Snowden and Cambridge Analytica episodes, concerns have been raised by governments and regulators on protecting consumer data collected and transmitted by various digital firms. Driven by concerns of privacy, national security, surveillance, and cyber terrorism, governments around the world have been erecting barriers in cyberspace through data localization. The extent of data localization varies from free flow of data, to stringent restrictions requiring all data to be stored only within the territorial jurisdiction of the country. Though there are certain legitimate concerns regarding protection of personal data, scholars and liberal economists have long proclaimed that any restrictions on the Internet and associated digital trade will have serious economic consequences. Data localization affects digital trade between consumers and producers of digital services to varying degrees. In this paper, we use agent based modeling to study the properties and behaviours of consumers and producers under varying data localization regimes. An augmented gravity model of trade with iceberg coefficient is incorporated to reflect distance-related costs between producers and consumers. Varying data localization compliance costs are included to reflect the effect of non-tariff barriers of data restrictions. Our extensive simulations indicate that there is often clustering of consumers around local firms in highly restrictive data localization regimes, thus enabling local firms to effectively compete against global multinationals. However, results also indicate that while free cross-border data flow enables intense competition amongst producers, data localization restrictions often limit consumer choice due to its effect on price and quality of services.     

Price competition when three are few and four are many

I examine price competition in a market for a homogeneous good when consumers observe prices subject to a random shock (perception error). When firms have symmetric costs, there exists a unique equilibrium in pure strategies, which is symmetric. When there are up to three sellers in the market, the sellers extract the entire consumer surplus. However, with at least four firms, assuming that the marginal cost is sufficiently low relative to consumers’ valuation, both consumers and producers may enjoy a positive surplus. The marginal-cost pricing is never observed in an equilibrium with finitely many firms. Potential policy implications are discussed.     

Efficiencyv. collusion: Evidence cast in cement

Through the 1970s and 1980s, the U.S. portland cement industry experienced a significant increase in average plant size and market concentration. A simultaneous equation model is developed to examine the effects of plant size and concentration on costs, prices and margins in that industry. The results indicate the presence of significant scale economies, but also show that prices and margins are increasing in concentration. Further analysis shows that almost one third of the cost savings associated with larger plants are passed on to producers through higher margins resulting from concomitant increases in concentration, rather than to consumers as lower prices.     

TYING IN TWO‐SIDED MARKETS WITH MULTI‐HOMING*

This paper analyzes the effects of tying on market competition and social welfare in two‐sided markets when economic agents can engage in multi‐homing by participating in multiple platforms to reap maximal network benefits. The model shows that tying induces more consumers to multi‐home and makes platform‐specific exclusive content available to more consumers, which is beneficial to content providers. As a result, tying can be welfare‐enhancing if multi‐homing is allowed, even in cases where its welfare impacts are negative in the absence of multi‐homing. The analysis thus can have important implications for recent antitrust cases in industries where multi‐homing is prevalent.     

The potential benefits of herbicide-resistant transgenic rice in Uruguay: Lessons for small developing countries

In many developing countries, the potential benefits from adopting a transgenic variety developed by a multinational corporation are limited by the crop’s small production base. This paper presents an ex-ante evaluation of the economic impact of herbicide resistant transgenic rice in a small developing country, Uruguay. To fully account for the multinational’s market power, the firm’s seed markup is assumed to affect the adoption rate for the variety. Stochastic simulation techniques are employed to understand how potential benefits may vary with changes in technology, yield, costs, and adoption parameters. The results indicate a $1.82 million mean net present value for producers from the development and utilization of transgenic rice in Uruguay and $0.55 million for the multinational. These relatively small multinational firm benefits suggest that a firm will not undertake significant efforts to develop transgenic varieties adapted to local conditions without either strategic partnerships with local institutions or access to wider regional markets.     

Farmer organization,collective action and market access in Meso-America

Farmer organization and collective action are often seen as key factors in enhancing farmers’ access to markets. Often, too little attention is directed at (a) the most appropriate types of organization; (b) whether organization makes less or more sense in the case of producers of an undifferentiated commodity or a higher value product; (c) whether the public or private sector is best placed to support farmer organizations; and (d) the conditions necessary for ensuring their economic viability. Research in Mexico and Central America explored these issues for commodity maize and high value vegetables, respectively. The benefits of farmer organization are more evident in the vegetable sector, characterized by high transaction costs associated with market access. However, horticultural farmer organizations in Honduras and El Salvador include less than 5% of total horticultural producers. This is possibly due to farmer organizations’ limited business skills and non-replicable organizational models. There is less incentive for maize farmers to organize to access output markets as the transaction costs are relatively low. The benefits of maize farmer organization are clearer when it comes to accessing inputs such as credit, seed and fertilizer. Farmer organization is a critical factor in making markets work for the poor, but the role and timing of public and private investment in these organizations is poorly understood.     

The Adverstising Market in a Product Oligopoly

A model is developed in which producers in a differentiated product market compete in prices and informative advertising. The model also includes commercial media, which are linked to producers through the advertising market and to consumers through the media market. We investigate how certain market parameters, such as media market differentiation or product market differentiation, affect the competitive level advertising chosen in the market. The model shows that less product differentiation or more media differentiation leads to a higher market level of advertising. In the case of sufficiently high media differentiation, levels of advertising are in excess of the social optimum.     

Consumer Trial,Continuous Use,and Economic Benefits of a Retail Service Innovation: The Case of the Personal Shopping Assistant

Service innovations in retailing have the potential to benefit consumers as well as retailers. This research models key factors associated with the trial and continuous use of a specific self‐service technology (SST), the personal shopping assistant (PSA), and estimates retailer benefits from implementing that innovation. Based on theoretical insights from prior SST studies, diffusion of innovation literature, and the technology acceptance model (TAM), this study develops specific hypotheses and tests them on a sample of 104 actual users of the PSA and 345 nonusers who shopped at the retail store offering the PSA device. Results indicate that factors affecting initial trial are different from those affecting continuous use. More specifically, consumers' trust toward the retailer, novelty seeking, and market mavenism are positively related to trial, while technology anxiety hinders the likelihood of trying the PSA. Perceived ease of use of the device positively impacts continuous use while consumers' need for interaction in shopping environments reduces the likelihood of continuous use. Importantly, there is evidence on retailer benefits from introducing the innovation since consumers using the PSA tend to spend more during each shopping trip. However, given the high costs of technology, the payback period for recovery of investments in innovation depends largely upon continued use of the innovation by consumers. Important implications are provided for retailers considering investments in new in‐store service innovations. Incorporation of technology within physical stores affords opportunities for the retailer to reduce costs, while enhancing service provided to consumers. Therefore, service innovations in retailing have the potential to benefit consumers as well as retailers. This research models key factors associated with the trial and continuous use of a specific SST in the retail context, the PSA, and estimates retailer benefits from implementing that innovation. In so doing, the study contributes to the nascent area of research on SSTs in the retail sector. Based on theoretical insights from prior SST studies, diffusion of innovation literature, and the TAM, this study develops specific hypotheses regarding the (1) antecedent effects of technological anxiety, novelty seeking, market mavenism, and trust in the retailer on trial of the service innovation; (2) the effects of ease of use, perceived waiting time, and need for interaction on continuous use of the innovation; and (3) the effect of use of innovation on consumer spending at the store. The hypotheses were tested on a sample of 104 actual users of the PSA and 345 nonusers who shopped at the retail store offering the PSA device, one of the early adopters of PSA in Germany. Data were analyzed using logistic regression (antecedents of trial), multiple regression (antecedents of continuous use), and propensity score matching (assessing retailer benefits). Results indicate that factors affecting initial trial are different from those affecting continuous use. More specifically, consumers' trust toward the retailer, novelty seeking, and market mavenism are positively related to trial, while technology anxiety hinders the likelihood of trying the PSA. Perceived ease of use of the device positively impacts continuous use, while consumers' need for interaction in shopping environments reduces the likelihood of continuous use. Importantly, there is evidence on retailer benefits from introducing the innovation since consumers using the PSA tend to spend more during each shopping trip. However, given the high costs of technology, the payback period for recovery of investments in innovation depends largely upon continued use of the innovation by consumers. Important implications are provided for retailers considering investments in new in‐store service innovations. The study contributes to the literature through its (1) simultaneous examination of antecedents of trial and continuous usage of a specific SST, (2) the demonstration of economic benefits of SST introduction for the retailer, and (3) contribution to the stream of research on service innovation, as against product innovation.     

Trademarks,market power,and information

This paper examines the advantages of market power acquired or maintained through trademark. Without denying the benefits to consumers of trademark protection, several objections to trademark-based dominant positions are raised:-1- the possibility that in certain cases the social benefits are less than the sum of private benefits, and less than the social costs, of trademark protection;-2- the link between trademarks and incorrect perceptions of quality differentials; and-3- certain problems which may arise in tying two trademarked products.     

Indirect networks: an intangible resource for biotechnology innovation

In the context of the emergence of new modular organizational forms, especially in high-tech sectors such as the biotechnology sector, this article proposes that while a firm observes benefits from direct alliances, it also benefits from indirect linkages. First, a theoretical framework revolving around indirect ties is built on the basis of social network and innovation management literature. It ends with the proposition of two research hypotheses linking the indirect network position of a firm to its innovation capacities. To test those hypotheses, data on strategic partnerships and collaborations were collected through 40 interviews with biotech firms from the nutrition sector in the biotech clusters of Quebec (Canada). Using network analysis, centrality measures and hierarchical regressions, results of this study indicate that by occupying a central position in a network of indirect ties, a firm is more likely to access useful knowledge from its direct partners and increase innovation. We suggest, as a conclusion, that indirect network position could be considered as an intangible strategic resource for biotech firms.     

Referrals in search markets

This paper compares the equilibrium outcomes in search markets with and without referrals. Although it seems clear that consumers would benefit from referrals, it is not at all clear whether firms would unilaterally provide information about competing offers since such information could encourage consumers to purchase the product elsewhere. In a model of a horizontally differentiated product market with sequential consumer search, we show that valuable referrals can arise in the equilibrium: a firm will give referrals to consumers whose ideal product is sufficiently far away from the firm's offering. We allow firms to price-discriminate among consumers, and consumers to misrepresent their tastes. We found that the equilibrium profits tend to be higher in markets with referrals than in markets without. Consumers tend to be better off in the presence of referrals when search costs are not too low, and under a certain parameter range, referrals lead to a Pareto improvement.     

What can we learn from past price stabilization policies and market reform in Mexico?

This paper reviews experience with policy reforms in the maize sector in Mexico, beginning in the 1980s with particular reference to impacts on price variability. It analyses Mexico’s transition from past price stabilization policies under a state-trading enterprise to market reforms implemented during the 1990s. The nature, extent, and costs to producers and consumers of maize policies is discussed for both the pre-reform and the reform periods. Although wide ranging reforms have been introduced, impacts on efficiency and fiscal outlays have been less than expected.     

Speculative storage in imperfectly competitive markets

Markets for many commodities are characterized by imperfectly competitive production as well as substantial storage by speculators who are attracted by significant price volatility. We examine how speculative storage affects the behavior of an oligopoly producing a commodity for which demand is subject to random shocks. Speculators compete with consumers when purchasing the commodity and then subsequently compete with producers when selling their stocks, resulting in two opposing incentives: on the one hand, producers would like to increase production to capture future sales in advance by selling to speculators; while on the other hand, they would like to withhold production to deter speculation, thereby eliminating the additional supply from speculators in future periods. We find that the incentive to sell to speculators can be quite strong, potentially resulting in prices sufficiently high to drive consumers from the market. Furthermore, these incentives are non-monotonic in the number of producers: speculative storage occurs more frequently in a relatively concentrated oligopoly than in the extremes of monopoly or perfect competition.     

Consumer valuation of information about food safety achieved using biotechnology: Evidence from new potato products

This study focuses on the role of food labels and information for affecting consumers’ valuation of food safety achieved through application of biotechnological (biotech) methods. In 2002, potato products cooked to a high temperature were first reported to contain the human carcinogen acrylamide. Research discoveries using genetic engineering can substantially reduce carcinogenic-forming potential, and thereby increase food safety of potato products. Adult consumers from three distant regions of the U.S. were the subjects in lab auctions of potato products. They engaged in distinct rounds of bidding, first without packaged information and again after receiving information about the food safety risks and benefits of new biotech potato products. The study finds that willingness-to-pay (WTP) for these new potato products are not significantly different from conventional potato products under no information. However, exposure to a scientific perspective and scientific plus industry perspectives increases participants’ willingness-to-pay for the new potato products and reduces willingness-to-pay for conventional products. Exposure to the negative perspective on the new technology significantly reduces willingness-to-pay. Consumer valuation of the new potato products is affected by food labels, information, and consumer attributes. A consumer information program could be needed to gain consumer acceptance of these potato products or other foods that have been genetically modified to increase certain food safety dimensions.     

Preferences of Scotch malt whisky consumers for changes in pesticide use and origin of barley

In a case study related to Scotch malt whisky production, this study analyses consumers’ perceptions and preferences regarding two aspects that have emerged in the debate on sustainable production and consumption, and on environmentally responsible food choice, namely (i) the use of pesticides in agriculture, and (ii) the provenance of food ingredients. We carried out a choice experiment to investigate preferences and estimate Willingness to Pay of Scotch malt whisky consumers for pesticide use restrictions and the potential impact on the production of one of its essential ingredients, barley. Using latent class models, we find that about half of the respondents are non-demanders with respect to both attributes, and only a third of the sample population are willing to pay for further pesticide restrictions. Demand for more environmentally responsible production of Scotch malt whisky is therefore limited, indicating that in the case of Scotch malt whisky, consumers are not likely to be key to driving sustainable production. With respect to barley provenance, being able to claim a 100% Scottish product could be a plausible commercial option for some producers to pursue in a competitive market. Methodologically, the scale-adjusted latent class model proved to be successful in uncovering preference heterogeneity and its sources, in including non-demanders in the analysis and in accounting for differences in scale amongst respondents.
