Ano: 2006 URL: http://purl.umn.edu/25360 IS 'GETTING THE PRICES RIGHT' ALWAYS RIGHT? HOW TRADE LIBERALIZATION CAN FAIL AgEcon Gaitan, Beatriz; Pavel, Ferdinand. We present a general equilibrium model with oligopsonistic market structure in one of the sectors. Buyers of inputs can set the price of inputs by being involved in rent seeking activities. The framework developed is applied to the Bulgarian economy in particular to the agro-food chain. From the application to the Bulgarian economy we find that if there are market imperfections, such as oligopsonistic behavior in the economy, there are no significant welfare gains from free trade. Significant welfare gains from trade are observed only when a competitive structure prevails. We show that eliminating this market imperfection can bring important welfare implications and an efficient reallocation of resources.

Ano: 2000 URL: http://purl.umn.edu/21881 Modelling Agricultural Commodity Markets under Imperfect Competition AgEcon Soregaroli, Claudio; Sckokai, Paolo. In this paper, we develop a model that explains the exporters’ behaviour in international commodity markets considering explicitly the case of an imperfectly competitive structure of these markets. More specifically, drawing from the imperfect competition and trade literature, we derive price transmission equations between producer and consumer prices and between producer and export prices that can be included in large commodity models in order to verify how results of these models change assuming the imperfect competition hypothesis. The results obtained carrying out a simple simulation exercise, with two competing exporting countries and one importing region, show the relevance of assuming imperfect competition in commodity markets.

Ano: 2011 URL: http://purl.umn.edu/116012 Assessing the Impact of Recent Trade Policy Changes in the Banana Market under Alternative Market Structures AgEcon Anania, Giovanni; Scoppola, Margherita. The paper focuses on the importance of the assumptions made about market structure and firm behaviors in empirical trade policy analysis. It addresses this issue with reference to recent changes in the EU import regime for bananas, namely the Economic Partnership Agreements and the December 2009 WTO agreement on bananas. The paper’s contribution to the literature on the issues addressed is threefold: first it develops two original models which incorporate imperfectly competitive market structures in a spatial modeling framework; then it proposes a methodology to assess the degree of market power in international trading which is applied to the banana market and, finally, it assesses how analysis of the implications of the most recent changes in the EU...

Ano: 2010 URL: http://purl.umn.edu/115436 Improving Market Access: The Role of Auctions in Converting Tariff-Rate Quotas into Single Tariffs AgEcon Joerin, Robert. Market access in the WTO is highly fragmented due to exceptions from GATT principles. Tariff-rate quotas (TRQs) stand in contradiction to the principle of the GATT, according to which all quantitative restrictions in international trade should be eliminated. Bhagwati’s theorem of the non-equivalence of tariffs and quotas leads to the conclusion that under imperfect competition, market access can be improved by converting TRQs into single tariffs. In order to find the ‘new’ tariff, Bergsten (1987) proposed to auction quotas and to use the realized auction price for setting the equivalent tariff. There is empirical evidence from auctions of TRQs in Switzerland that the observed auction prices are below the equivalent tariffs. This is in line with the...

Ano: 2009 URL: http://purl.umn.edu/51448 Climate Change, Energy Demand and Market Power in a General Equilibrium Model of the World Economy AgEcon Roson, Roberto; Bosello, Francesco; De Cian, Enrica. Future energy demand will be affected by changes in prices and income, but also by other factors, like temperature levels. This paper draws upon an econometric study, disentangling the contribution of temperature in the determination of the annual regional demand for energy goods. Combining estimates of temperature elasticities with scenarios of future climate change, it is possible to assess variations in energy demand induced (directly) by the global warming. We use this information to simulate a change in the demand structure of households in a CGE model of the world economy, in a set of assessment exercises. The changing demand structure triggers a structural adjustment process, influencing trade flows, regional competitiveness of industries and...
