are more exports always better comparing cash and in kind export subsidies cash and in kind export subsidies are compared it is found that the ability to enhance real farm income via export subsidies is sensitive both to the form cash vs in kind and the point of policy intervention in kind subsidies of the type granted under the export enhancement program can in fact reduce real farm income export subsidies are examined under three separate scenarios no target price or nonrecourse loan programs a target price but no nonrecourse loan program and a nonrecourse loan program but no target price program the presence of a nonrecourse loan program dampens the impacts of both cash and in kind export subsidies before the introduction of the export enhancement program eep two types of export subsidies had been used by the united states a direct cash subsidy for wheat exports and an export payment in kind pik for feed grains cotton rice and nonfat dry milk under the original export pik program exporters showing proof of export sales were given certificates redeemable for commodity credit corporation ccc commodities to be exported cochrane and ryan the eep reintroduced in kind export subsidies in 1985 this paper compares the relative effectiveness of cash and pik export subsidies in increasing agricultural exports real prices and real incomes because agricultural policy ultimately must be judged by how it affects agriculture s relative position in the economy the framework is general equilibrium the model considers the interplay between farmers international middlemen nonfarm producers domestic consumers and foreign consumers the analysis shows that the ability to enhance real farm income is sensitive both to the form cash subsidies versus pik subsidies and point of policy intervention at the farm or export level in particular the results demonstrate that pik subsidies of the type granted under the eep can decrease real farm income from production agriculture s perspective an export pik program even though it raises total agricultural exports is not a sure path to improving agriculture s position in the general economy sometimes less exports are better we first introduce the model the second section reexamines solely for comparative purposes the consequences of introducing cash subsidies to commercial exporters the third section examines in kind export subsidies given to farmers and the fourth considers in kind subsidies to commercial traders the fifth section reexamines these results when the real target price of the agricultural good is fixed next tied pik export subsidies are considered finally the effects of contemporaneous existence of pricesupport operations on the results are discussed

united states export subsidies in wheat strategic trade policy or expensive beggar thy neighbor tactic this paper examines the domestic and international impacts of the u s export enhancement program eep for wheat eep uses targeted in kind subsidies to expand u s exports and was designed specifically to compete with subsidized exports from the european community ec we argue eep cannot be welfare improving for the u s even considering strategic trade theory we then model eep as an in kind constrained targeted export subsidy and determine its price quantity and budgetary effects empirical results show that no exporting country gains from eep and that the intended loser the ec is only slightly harmed we find the export subsidies generate only a small increase in u s wheat exports eep is an expensive program based on our estimates for 1988 government cost of additional wheat exports under eep reached 469 per metric ton

back to the futures an assessment of market performance on the early winnipeg grain exchange in this paper i offer a quantitatively rich historical perspective with which to consider western canada s recent return to private grain marketing i assess how futures markets on the winnipeg grain exchange wge performed before the canadian wheat board and i consider the extent to which this performance contributed to the canadian government s decision to create the board i conclude despite significant agrarian dissatisfaction with private grain marketing on the wge the canadian government ultimately proscribed futures trading because it was incompatible with the cwb model which the canadian government needed in order to stabilize farm incomes particularly in the aftermath of the great depression resume retour aux contrats a terme une evaluation de la performance du marche au temps du winnipeg grain exchange l auteur offre une perspective historique qui s appuie sur de riches donnees quantitatives qu il utilise pour evaluer le recent retour de la mise en marche privee dans l ouest canadien il evalue la performance des marches a terme sur le winnipeg grain exchange wge avant l arrivee de la commission canadienne du ble cwb et jusqu a quel point cette performance a contribue a la decision du gouvernement du canada de mettre sur pied la cwb il conclut que malgre le mecontentement significatif du monde agricole quant a la mise en marche privee sur le wge le gouvernement du canada mit fin a ses pratiques parce que celles ci etaient incompatibles avec le modele de la cwb dont le canada avait besoin pour stabiliser les revenus des fermiers surtout dans la periode qui a suivi la grande crise

marketing margins and price uncertainty the case of the u s wheat market this paper seeks to determine the effect of changes in output price risk on marketing margins a theoretical model of price determination in a marketing channel with risk averse firms is developed this model shows that if marketing firms are competitive and decreasingly absolute risk averse then an increase in output price risk should result in higher expected marketing margins empirical evidence from the wheat marketing channel supports the theoretical model increased price variability significantly increases wheat marketing margins for both the farm mill margin and the mill retail margin these results suggest a potential benefit from price stabilization programs

a simulation model of the u s export enhancement program for wheat nash bargaining game models representing negotiations of export enhancement program eep sales are combined with a quarterly spatial price equilibrium model representing non eep world wheat trade to simulate the eep s impact in late 1985 and early 1986 the benefits of the eep in terms of increased u s export revenues adjusted for subsidy costs are estimated to be less than one percent of total u s revenues for the first quarter of 1986 model simulations also show a lowering of the ccc loan rate to have a much greater potential for increasing u s wheat exports than the eep as operated

redefining recs part 2 untangling certificates and emission markets abstract renewable energy and greenhouse gas emissions markets are currently in a state of confusion regarding the treatment of renewable energy certificate recs how should emission trading schemes treat recs how can emission mitigation policies provide real incentives for renewable generation the objective of rec markets should be to promote additional renewable energy investments the author asserts that defining recs in terms of attributes especially off site attributes does not further this goal ambiguous language such as environmental attribute or environmental benefit creates confusion in the marketplace while failing to address the relevant coordination issues with renewable portfolio standard compliance markets voluntary emission offset markets or emission cap and trade markets specifically defining recs in terms of off site attributes creates a number of problems including that once an emissions cap and trade scheme is in place such definitions of a rec can become indefensible the author proposes to redefine recs in terms of on site attributes which resolves the aforementioned problems and allows compliance and voluntary renewable energy and emission markets to function without conflicts ideally environmental commodities should be homogeneous first best measures of the relevant environmental good as well as easily measured and verified the author proposes tradable environmental commodities that achieve these characteristics

measuring the degree of market power exerted by government trade agencies the principle of profit maximization is used to derive an equilibrium condition for noncompetitive markets and to provide explicit parametric tests for market power exerted in both domestic and foreign markets by a government trade agency our study goes beyond previous work by considering simultaneous exertion of market power in both domestic and foreign markets and by jointly estimating market power parameters with cost and demand parameters these innovations allow nested tests of market power as opposed to prevailing nonnested tests based on simulation models or conditional tests based on prior estimates of demand and cost parameters japan is found to exert a high degree of monopsony power in the world wheat market and no monopoly power in the domestic market

price discrimination in free entry markets using a spatial model of monopolistic competition we investigate price discrimination in free entry zero profit markets we show that when brands are heterogeneous competition does not prevent discrimination the power to earn economic profits is not necessary for a firm to maintain discriminatory prices our model treats formally the fact that consumers difer not only in the utility they derive from a good but also in how strongly they prefer one brand over all others in markets where firms are very competitive sorting consumers on the strength on brand preference produces larger price differentials between groups than sorting on the basis of consumers reservation prices for the good when firms sort customers on the basis of strength of brand preference however we find that the output and welfare effects are generally less favorable than when sorting is more closely related to consumers reservation prices

wheat demand in japanese flour milling industry a production theory approach a production approach based on the translog cost function is used to analyze import demand for wheat differentiated by class and country of origin in the japanese wheat flour milling industry results indicate that us wheat faces strong competition in the japanese wheat market but its multiple classes and end use characteristics enable the us to preserve the largest market share in japan

the cost effectiveness of the u s export enhancement program bonus allocation mechanism the u s export enhancement program is evaluated from the perspective of the cost effectiveness of its bonus allocation mechanism the current mechanism resembles a discriminatory price common value auction however auction theory suggests that a discriminatory auction may not be optimal in this setting for several reasons this article evaluates the current format relative to an alternative uniform price auction estimation results reveal evidence of strategic bidder behavior under the current format and simulations suggest that adopting a uniform price auction format for bonus allocation may yield considerable savings to the treasury by eliminating incentives to pad bids and increasing participation in the auction

the impact of agricultural subsidies on global welfare increasing global nature of the world economy have sparked much debate as to whether globalization is a vehicle for growth and development or a bane to society the debate is not simply one between the informed and the uneducated some of the most respected economists in the world disagree as to the impacts of globalization stiglitz 2002 refers to the devastating effect that globalization can have on developing countries on the other hand bhagwati 2004 holds that globalization can be beneficial for both developed and developing countries he postulates that for this to occur there must be a set of new policies and institutions that will help developing countries handle increased volatilities result

price discrimination by u s and german exporters the insensitivity of the u s trade balance to the sharp depreciation of the dollar in the past three years has revived interest in the relationship between exchange rates and the trade balance a central issue in most analyses of the relation between the current account and the exchange rate concerns the price adjustment process the simple integrated competitive market model predicts that local currency prices should change in proportion to the nominal exchange rate for a country too small to influence world prices the relationship between local currency import prices and exchange rates has been referred to as the pass through relationship in the empirical literature in international economics if the proportional relationship between import prices and exchange rates holds pass through is said to be complete accounts of recent u s experience cite the failure of dollar prices of imported goods to rise in proportion to exchange rates i e incomplete pass through as an important factor in explaining the persistence of the trade deficit unfortunately observations on pass through alone provide limited insight into the behavior of markets since incomplete pass through is consistent with at least two fundamentally different paradigms one is the standard competitive model of trade in which the law of one price holds but exchange rate fluctuations are associated with large changes in import demand due to other factors for example if dollar appreciation is correlated with increases in world demand and industry marginal cost is increasing then pass through will be less than complete the other is an imperfectly competitive model in which exporters are capable of price discriminating across destination markets a phenomenon paul krugman 1987 has labeled pricing to market in this model incomplete pass through is typically associated with fluctuations in the markup of price over marginal cost on exports 2 these fluctuations in markups are believed to be countryspecific they do not reflect the behavior of prices to other export destinations both models are plausible explanations of recent u s experience unfortunately it is impossible to distinguish between these competing models using only information on import prices and exchange rates for a single country in order to distinguish between the competing models an empirical analysis of goods prices and exchange rates must be capable of measuring either marginal cost or the markup over marginal cost either of these tasks poses formidable empirical problems much of the empirical literature in industrial organization has been concerned with precisely these issues since markups are an important measure of the competitiveness of industries

valuing varieties with imperfect output quality measurement markets for agricultural products may be inefficient when signals do not adequately reflect product characteristics important to market participants preferences can be explicitly reflected in price premiums for measurable characteristics using hedonic methods however when product quality information is costly to obtain the problem is compounded bundling of quality traits by variety can serve to signal product quality a procedure is developed to derive the value of different varieties in meeting buyer demands an application to the hard red spring market wheat illustrates the use of a procedure to distinguish among varieties and provides empirical support for the existence of akerlof s lemon market in the release of wheat varieties

domestic costs of statutory marketing authorities the case of the canadian wheat board the canadian wheat board cwb is a statutory marketing authority with exclusive control over exports of canadian wheat and barley and sole authority over domestic marketing of milling wheat and malting barley it is a government marketing board with implicit monopoly rights over the supply of wide ranging marketing services to farmers but with no legal responsibility to farmers these characteristics fit a stylized niskanen model of bureaucratic decision making where the cwb is modeled as supplying excess marketing services to farmers allowing the market to determine the quantity of marketing services would result in lower marketing costs and presumably higher farm incomes

targeted agricultural export subsidies and social welfare global export subsidies are known to be welfare reducing this paper demonstrates that a small targeted subsidy can increase the welfare of the subsidizing country by exploiting differences in excess demand elasticities targeted export subsidies can also increase the subsidizing country s welfare by exploiting transportation cost differences excess supply elasticities of competitors or excess demand elasticities of markets supplied by competitors when markets are shared an empirical model of the world wheat market illustrates the theoretical conclusions an optimal targeted subsidy scheme causes a small increase in u s welfare but with major disruptions in world trade flows

measuring the intensity of competition in export markets abstract this paper develops an approach to measuring the intensity of competition in international markets using readily available data on destination specific values and quantities of exports at the seven digit industry level the intensity of competition a group of exporters faces in a particular export market is measured by the residual demand elasticity the group faces this elasticity is identified by exchange rate shocks which rotate the supply relation of the source country export group relative to competitors located in other countries we apply this method to german exports of beer and us exports of linerboard paper the resulting estimates of market power appear to be plausible and consistent with other indicators of competition e g market shares the number of competitors providing support for the applicability of our framework in measuring competition in international markets

markup adjustment and exchange rate fluctuations evidence from panel data on automobile exports abstract this paper uses data on bilateral automobile export prices from the usa germany and japan to gauge the importance of markup adjustment driven by exchange rate movements across several destination markets we find that japanese exports are characterized by a high degree of markup adjustment designed to stabilize the price measured in the buyer s currency there is weak evidence for such behavior on the part of german exporters and no evidence of markup adjustment by us exporters where it exists markup adjustment tends to be highly persistent the dynamic pattern of markup adjustment is consistent with invoicing in the exporter s currency except for exports to the usa and canada

probabilistic decision model of wind power investment and influence of green power market this paper presents results from a model of a representative wind power investor s decision making process using a monte carlo simulation of a project financial analysis data in the form of probability distribution functions pdfs for key input variables were collected from interviews with investors and other professionals active in the u s wind power industry using a formal expert elicitation protocol this study presents the first quantitative estimates of the effect of the u s voluntary renewable energy certificate rec market on renewable energy generation the results indicate that the investment decisions of wind power project developers in the united states are unlikely to have been altered by the voluntary rec market the problem with the current voluntary rec market is that it does not offer developers a reliable risk adjusted revenue stream consequently the claims by u s green power retailers and promoters that voluntary market recs result in additional wind power projects lack credibility even dramatic increases in voluntary market rec prices in the absence of long term contracts were found to have only a small effect on investor behavior

price discrimination in the context of vertical differentiation an application to canadian wheat exports this study examines the ability of the canadian wheat board cwb to price discriminate in bread wheat exports this study models wheat as a vertically differentiated intermediate good and modifies the model of vertical differentiation by mussa and rosen to the realities of wheat import demand the conceptual model isolates the bases of price discrimination and demonstrates that the cwb s ability to exploit cost differences in pricing depends on the extent of the differentiation between canadian and u s wheat this model is implemented using monthly confidential price data provided by the cwb for exports to japan the united kingdom and two markets aggregating remaining exports through canada s west and east coasts for 1982 1994 the data indicate that the cwb charges different prices to different countries for wheat of the same grade and protein content results from the model indicate that the price difference between any two markets is not completely explained by elements of perfect competition however the evidence is mixed regarding the ability of the cwb to utilize all the instruments available to price discriminate thus the cwb s pricing strategy may be more complex and dynamic than the prescription for static producer surplus maximization derived in this study

economies of scale and market structure in international grain trade a large body of literature has examined international grain trade in imperfectly competitive models the article develops a two stage duopoly model that considers a private trader and a state trading enterprise ste competing on a foreign market the key difference between the private trader and the ste is their international organization while the ste makes use of external agents to export the private firm may choose to internalize international transactions the game is solved for different modes of competition and under both assumptions of homogeneous and differentiated products in order to assess how these assumptions affect the outcome of the game the results of the game are examined by using numerical examples the analysis shows that external shocks on export markets may result in a change of market structure and consequently of market shares these effects depend on the initial market structure furthermore the degree of product differentiation and the assumed mode of competition significantly affect the relative values of transaction and fixed costs at which the market structure changes

competition and collusion in the american automobile industry the 1955 price war movements in total quantity and in quality adjusted price suggest a supply side shock in the american automobile market in 1955 this paper tests the hypothesis that the shock was a transitory change in industry conduct a price war the key ingredients of the test are alternative equilibrium models of oligopoly under product differentiation in nonnested cox tests of hypotheses a collusive solution is sustained in 1954 and in 1956 while a competitive solution holds in 1955 the result does not appear to be an artifact since it is robust in tests against alternative specifications copyright 1987 by blackwell publishing ltd

policies and market factors driving wind power development in the united states abstract in the united states there has been substantial recent growth in wind energy generating capacity with growth averaging 24 percent annually during the past five years about 1700 mw of wind energy capacity was installed in 2001 while another 410 mw became operational in 2002 during 2003 development activity has remained strong with an estimated 1600 mw of capacity installed with this growth an increasing number of states are experiencing investment in wind energy projects currently about half of all states host at least one wind power project this paper explores the key factors at play in the 12 states in which a substantial amount of wind energy capacity has been developed or planned some of the factors that are examined include policy drivers such as renewable portfolio standards rps federal and state financial incentives as well as market drivers such as consumer demand for green power natural gas price volatility and wholesale market rules

statistical dynamics and walras law abstract much interest has been shown on identifying the chaotic behavior generated from t tonnement process recently the aim of this article is to direct the research in exploring its statistical dynamical properties two typical types of ergodic t tonnement processes restricted t tonnement and unrestricted t tonnement have been studied their long run statistical characteristics such as time average of price excess demand and inflation rate are discussed in theory and by computer simulations

in kind export subsidies for processed and bulk goods this research analyzes the interaction between a bulk commodity and a processed good under in kind export subsidies an in kind export subsidy lowers the export price of the good on which it is paid the other price changes are ambiguous a numerical model for u s wheat and flour illustrates these conditions given the parameters of the model an in kind payment using wheat lowers flour prices and the export price of wheat the u s domestic wheat price rises when flour is used for the payment u s wheat and flour prices rise while the foreign flour price falls

the welfare effects of targeted export subsidies a general equilibrium approach a three country model of export subsidies is developed with an exporter an importer and a neutral country which can act on either side of the market when the neutral country is an exporter the country offering a targeted export subsidy always suffers a welfare loss however when the neutral country is an importer the possibility of a paradoxical result that the subsidizing country can gain and the subsidized country can lose is shown to exist and the conditions under which this result occurs are derived the model fails to provide justification on national welfare grounds for widespread use of targeted export subsidies such as the export enhancement program

targeted export subsidies as an exercise of monopoly power a country with monopoly power in its export good normally benefits from an export tax however if it exports to two countries and the tax on exports to one is suboptimal then it may be best to subsidize exports to the other this is more likely the smaller is the import demand elasticity in the country being taxed suboptimally and the larger the elasticity in the other it is also more likely the larger are exports to the first and the smaller are exports to the other finally it is more likely the less elastic is home export supply

redefining recs part 1 untangling attributes and offsets abstract renewable energy and greenhouse gas emissions markets are currently in a state of confusion regarding the treatment of renewable energy certificates recs should consumers buy recs or emission offsets after examining this question the author concludes that recs are not equivalent to emission offset credits and as currently defined the retiring of a rec may have no impact on emissions from electric power generation consumers who purchase recs in voluntary green power markets are providing financial assistance to renewable generators in the form of a production subsidy generators that sell recs are not transferring emission reductions since they are unlikely to have ownership or the ability to quantify reductions using a commonly accepted standard more importantly recs currently sold in voluntary markets do not pass credible additionality tests and can at best be expected to have a market demand effect which will be less than the supply of recs on the market rec definitions that use the term environmental attributes or environmental benefits are almost universally ambiguous providing the mistaken impression that consumers are purchasing a good instead of subsidizing a public good

third country effects and second best grain trade policies export subsidies and bilateral liberalization an incumbent export subsidy will affect the size and distribution of gains from bilateral trade liberalization but in theory may still permit increased trade volume and mutual benefits from freer trade these points are illustrated using the case of canada u s durum wheat trade which grew rapidly following the 1989 canadian u s free trade agreement custa an empirical analysis suggests that given its export enhancement program eep the united states lost from freer trade in durum conversely freer trade in durum means greater gains to the united states from eliminating eep

end use performance uncertainty and competition in international wheat markets the input characteristic model icm is expanded in this paper to account for technical coefficient uncertainty the model is used to analyze effects of price and quality on competition in the u k wheat import market results are used to identify critical quality characteristics and impacts of technical coefficient uncertainty on import demand the expected values for most characteristics of u s wheat have greater variances than those of canadian wheat results show that both the characteristic s level and variance are important in determining import market shares

exchange rate pass through when market share matters the authors investigate the pass through from exchange rates to import prices when firms future demands depend on their current market shares they show that profit maximizing foreign firms may either raise or lower their dollar export prices when the dollar appreciates temporarily i e the pass through may be perverse and that current import prices may be more sensitive to expected future exchange rates than to current exchange rates they present evidence that suggests the behavior of expected future exchange rates may provide a clue to the puzzling recent behavior of u s import prices copyright 1989 by american economic association

statistical dynamics and economics abstract it is shown in this paper how complex economic dynamics can be characterized using the statistical or distributional theory of dynamical systems the basic concepts of the latter are summarized then applications to supply and demand adjustments in competitive markets aggregate business fluctuations and economic growth in the very long run are briefly reviewed

goods prices and exchange rates what have we learned import prices typically change by a smaller proportion than the exchange rate between the exporting and importing country recent research indicates that common currency relative prices for similar goods exported to different markets are highly correlated with exchange rates between those markets this evidence suggests that incomplete pass through is a consequence of third degree price discrimination while distance matters for market segmentation borders have independent effects the source of the border effect has not been clearly identified furthermore there is little evidence yet to suggest substantial market power is implied by the observed price discrimination

rationalizing agricultural export subsidies export subsidies are an important form of agricultural policy especially for large traders such as the united states and the european community a number of small countries also use export subsidies in effect e g saudi arabian wheat or canadian dairy products in that the domestic price is set well above world levels and surplus production is dumped onto the world market a number of recent contributions to trade theory have argued that export subsidies can be welfare enhancing for the subsidizing country and by implication that the policy choice is consistent with the hypothesis that a benevolent government is pursuing pareto efficiency in the present paper we examine these arguments and present an alternative explanation of export subsidies utilizing the concept of efficient redistribution becker gardner 1983 in standard trade models arguments in favor of global export subsidies arise from failure to exploit market power in another good itoh and kiyono feenstra itoh and kiyono use a threegood model to show that subsidies on marginal goods defined as goods not exported at all or exported in small quantities can increase welfare in the subsidizing country a subsidy on marginal goods causes their production to increase and the supply of nonmarginal goods to decrease thereby raising the price of the nonmarginal goods and increasing the exporter s terms of trade feenstra also employs a threegood model and demonstrates that it is possible for the pattern of substitutability and complementarity across goods to allow subsidies to increase welfare the necessary condition is that the subsidized export be a stronger substitute for another exported good or a stronger complement for an imported good in the subsidizing country than abroad the export subsidy increases welfare by improving the terms of trade in the other imported or exported good the distortion in feenstra s model is the failure to exploit market power in the second or third market as an alternative to global export subsidies abbott paarlberg and sharples aps have examined targeted export subsidies and found that in some circumstances they can be welfare improving dutton later showed the aps result arises because they first constrain the export tax to the rest of the world to be zero so that it becomes theoretically possible for the best export tax to the targeted country to be negative the aps result hinges on differences in import demand elasticities and the exporting country s use of market power in order to price discrim

market power in renewable portfolio standards abstract renewable portfolio standard rps which requires a certain percentage of electricity production from renewables has received considerable attention one emerging issue is the possibility of strategic behavior in the renewable energy certificate credit rec market and its spillover effects on the electricity market this paper develops dominant firm competitive fringe models that account for market power we show that market power could have significant impacts on the rec and power prices in particular when a nonrenewable generator is a dominant firm and a renewable generator is a competitive fringe the nonrenewable firm has a strong incentive to lower the rec price even to zero for avoiding rec costs the zero rec price would negate price impacts in the power market thereby mitigating market power of the dominant firm however this could lead to an underinvestment in renewables in the long run as subsidies received by renewables in form of recs vanish therefore regulatory agencies need to carefully oversee the market performance to ensure a healthy development of renewable industries under the rps policies

the effect of financial constraints technological progress and long term contracts on tradable green certificates tradable green certificates tgcs have recently become a diffuse instrument to support renewable electricity in oecd countries although it is perhaps too early to draw a conclusive judgement on the effectiveness of this instrument in increasing renewable capacity and decreasing the price of certificates one view in the literature maintains that long term contracts are of particular importance for tgcs to be effective this paper contributes to this debate by analysing how financial constraints and technological progress can induce investors to hold pessimistic expectations of their ability to sell green certificates and still make a profit clearly these expectations will prevent investors from building new capacity to fulfil the quota comprised in tgcs and will keep the price of certificates traded in the market high as this kind of expectation is not influenced by most design features of tgcs one can conclude that long term contracts are particularly important in determining the effectiveness and cost effectiveness of these instruments some attention should therefore be paid to the features of the tgcs which induce obliged parties to offer long term contracts to renewable generators

hubs and high fares dominance and market power in the u s airline industry this article estimates the importance of route and airport dominance in determining the degree of market power exercised by an airline the results indicate that an airline s share of passengers on a route and at the endpoint airports significantly influences its ability to mark up price above cost the high markups of a dominant airline however do not create much of an umbrella effect from which carriers with smaller operations in the same markets can benefit the article suggests a number of possible explanations for this asymmetry

export credit as a mechanism for price discrimination export credit is shown to be a mechanism that facilitates price discrimination the scenario considered is one of competitive exporters selling to a cash importer with a relatively inelastic demand schedule and a credit importer with a relatively elastic demand schedule the spot markets of the two importing countries is assumed to be perfectly and costlessly arbitraged in the absence of export credit price discrimination is not possible even with government intervention if export credit is used but the government does not intervene price discrimination is also not possible export credit used in conjunction with targeted export price subsidies or loan guarantees generate rents from price discrimination despite the perfect arbitrage constraint

ethanol and trade an analysis of price transmission in the us market abstract this paper examines the price transmission mechanisms between domestic ethanol and imported ethanol in the us market using a multivariate johansen approach the data and model support one cointegrating relationship between the prices of domestically produced ethanol imported ethanol and other relevant products gasoline crude oil and corn the rejection of weak exogeneity of the imported ethanol price and corn price implies that these two prices would adjust to changes in the price linkage those empirical findings indicate that the impact of eliminating trade barriers on the imported ethanol price would spillover to the domestic ethanol price and subsequently to corn price

the export enhancement program prospects under the food agriculture conservation and trade act of 1990 abstract according to provisions of the 1990 us farm bill the export enhancement program eep will continue to be an important instrument in promoting us agricultural exports and in challenging subsidizing competitors like the european community ec with funding levels set at a minimum of 500 million annually through 1995 this research whose purpose is to evaluate the likely effectiveness of the wheat eep through 1995 concludes that the eep will have a significant effect on us wheat exports but will be subject to diminishing returns at levels higher than the annual minima and the ec will be only marginally affected by the eep as it can effectively counter the provisions of the eep at low cost

pricing to market behaviour of india s high value agri food exporters an empirical analysis of major destination markets the pricing behaviour of india s high value agricultural and food exporters in their major destination markets is examined using a pricing to market ptm model for noncompetitive and exchange rate related pricing behaviour the analysis was undertaken in a context where india is showing high commodity concentration in agricultural trade the econometric analysis employed is panel corrected standard errors pcse estimation technique the results indicated evidence of a greater degree of imperfect competition either through price discrimination across destinations or through imperfect exchange rate pass through the analysis of exchange rate effects showed that the local currency price stabilization by the indian exporters were more prominent than the amplification of exchange rates the analysis of the asymmetric effects of exchange rates on export prices showed that in most cases the depreciation of indian rupee had a greater impact than the appreciation moreover the results showed that the exchange rate pass through is sensitive to the kind of exchange rate index utilised in our analysis we found that the commodity specific exchange rate better predicts the pricing to market behaviour in most cases

multiple equilibria and chaos in a discrete tâtonnement process the purpose of this note is to demonstrate a sufficient condition for a discrete t tonnement process to lead to chaos in a general equilibrium model with multiple commodities the result indicates that as the speed of price adjustment increases the discrete t tonnement process is complex in a general equilibrium economy in which there are multiple equilibria

does arbitraging matter spatial trade models and discriminatory trade policies when modeling discriminatory trade policies such as targeted embargoes or targeted subsidies failure to explicitly include assumptions about the possibility of simultaneous exporting and importing may yield misleading results nonlinear programming and vector sandwich models implicitly set rules regarding arbitraging which may be at variance with actual policies and or country behavior the paper introduces an alternative spatial model which allows the researcher to explicitly incorporate her own assumptions about arbitraging an analysis of the 1980 u s embargo to the ussr shows how the proposed model performs relative to the most frequently used spatial trade models

further evidence on competition in the us grain export trade this study analyzes the relationship between export market structure and the pricing behavior of u s grain exporting firms a generalized cournot model is estimated by two stage least squares using pooled data sets for u s wheat and corn exports the cross sectional units correspond to foreign country destinations discriminatory export pricing behavior was found to be significantly related to export seller concentration u s market share total export volume and import market size yet the estimated coefficients linking these market structure variables to the export price markup were relatively small in magnitude suggesting little quantitative impact from market power copyright 1994 by blackwell publishing ltd

emerging differences in state grain trading australia and canada the australian wheat board awb and canadian wheat board cwb have attracted attention recently because they are two of the largest state trading enterprises stes engaged in agricultural trade they have traditionally been viewed as nearly sister agencies among major stes in the world market these two agencies historically had similar characteristics including price pooling cost pooling export sales monopolies monopoly powers within domestic markets grain quality control and government underwriting of initial producer prices and export credit however during the past 6 years similarities between the awb and cwb have begun to diverge and the importance of their differences is becoming increasingly apparent this paper identifies major emerging differences between the awb and cwb and explores potential explanations hypotheses for these dissimilarities a major point is that reforms in institutional design and legislative changes have given rise to emerging differences in key aspects of the marketing systems and performance

when renewable portfolio standards meet cap and trade regulations in the electricity sector market interactions profits implications and policy redundancy emission trading programs c t and renewable portfolio standards rps are two common tools used by policymakers to control ghg emissions in the energy and other energy intensive sectors little is known however as to the policy implications resulting from these concurrent regulations especially given that their underlying policy goals and regulatory schemes are distinct this paper applies both an analytical model and a computational model to examine the short run implications of market interactions and policy redundancy the analytical model is used to generate contestable hypotheses while the numerical model is applied to consider more realistic market conditions we have two central findings first lowering the co2 c t cap might penalize renewable units and increasing the rps level could sometimes benefit coal and oil and make natural gas units worse off second making one policy more stringent would weaken the market incentive which the other policy relies upon to attain its intended policy target

multiple equilibria and chaotic tâtonnement applications of the yamaguti matano theorem abstract this paper demonstrates sufficient conditions for the discrete time t tonnement process to lead to chaos in the competitive economy with only two commodities to prove that we use yamaguti matano theorem

international comparisons of pricing to market behavior this paper measures the degree of price discrimination across export destinations that is associated with exchange rate changes using u s u k german and japanese industry level data given the industries sampled more price discrimination across destinations is observed in the u k german and japanese data for industries that match across source countries however behavior is very similar across source countries furthermore destination specific price adjustment on exports to the united states from germany and japan is similar to price adjustment observed on shipments to other destinations most variation in the data appears to be related to industry copyright 1993 by american economic association
