u s bilateral trade flows and exchange risk during the floating period abstract this paper tests for real exchange rate risk effects on u s bilateral trade flows during the floating period using several new as well as previously used risk measures significant negative effects occur in five of six u s import flows and in two of six u s export flows with one export flow showing a significant positive effect these results are consistent with several previous findings for aggregate u s trade two risk measures using the forward exchange rate and assuming a time varying risk premium provide marginally more significant results than the others

secular and cyclical responses of u s trade to income an evaluation of traditional models in the three decades since guy orcutt s 1950 classic paper evaluating empirical research on international trade flows most trade research has focused on the influence of prices in the decade since the benchmark study by houthakker and magee 1969 examination of the role of prices has accelerated although income is consistently the most significant explanatory variable in these studies it is typically introduced only as a background control variable rather than as a variable of central interest the few explicit studies of the link from income to trade either use proxies such as delivery lags and inventory ratios to investigate the dynamics of the link e g gregory 1971 and artus 1973 or decompose income into trend deviation from trend and in one instance change in deviation from trend in an attempt to separate the secular and business cycle components e g ball eaton and steuer 1966 khan and ross 1975 and dunlevy 1980 stephen magee 1975 pp 188 193 211 214 provides a persuasive rationale for at least the spirit of the second line of research arguing that trade flows respond differently to secular and business cycle income changes and that regression estimates with income in level form mix these effects time domain decomposition is now an established practice with the trend response identified with secular forces like comparative advantage hence could be positive or negative in either demand or supply the deviation from trend response with a business cycle keynesian mechanism hence is likely to be positive in demand and negative in supply and the change in deviation from trend response with a sneed of adjustment constraint hence is likely to be negative the most recent evidence bearing on these issues is provided by dunlevy 1980 who finds that the effect of the business cycle income proxy deviation fromtrend income on the supply of exports for the united states and the united kingdom is positive rather than negative evidence contradicting both theory and evidence in earlier capacity pressure studies in this paper we first evaluate traditional regression estimates of income elasticities of demand and supply for u s imports and exports from 1955 to 1979 then compare these estimates to cross spectral estimates of the secular and business cycle responses of trade to income the spectral technique is used because by definition the approach estimates separately the secular and business cycle links between trade and income if the response of trade to movements in income does differ over cycles regression estimates of income elasticities may reflect bias and instability due to cycle varying parameters regression elasticity estimates with income in trend and deviation from trend forms do provide separate estimates but the decomposition is useful only to the degree that the two variables are accurate proxies for secular and business cycle movements in income it should be emphasized that we are not using spectral analysis to detect lead lag properties since these are more directly obtained in the time domain and are relatively trivial for our sample the unique advantage of spectral analysis is that it isolates secular and business cycle components directly even when the time domain link is only contemporaneous the paper is organized as follows section ii presents and evaluates time domain estimates of standard demand and supply equations for u s imports and exports and presents caveats regarding interpretation of the trend and deviationfrom trend income variables section iii proreceived for publication march 4 1981 revision accepted for publication may 12 1982 university of oregon an earlier draft of this paper was presented at the fall 1980 north american meeting of the econometric society we acknowledge helpful comments from s y kwack john mutti and two anonymous referees we also thank john pippenger for supplying the spectral program specx68 and the university of oregon for a faculty research grant remaining errors are solely ours i application of spectral methods to investigate trade income links was first suggested by ball eaton and steuer 1966 p 503 they were unable to use the technique however because the data series available at that time were too short

how is demand for natural gas determined across european industrial sectors abstract this paper estimates the response of manufacturing sectors natural gas demand to price and output changes the average response to future changes in absolute and relative prices of the manufacturing industry in an oecd country depends on the mix of manufacturing industries particularly with respect to energy intensity and substitution opportunities in production we estimate short and long run demand elasticities using a shrinkage estimator which allows heterogeneous demand responses across industries for each country our results show that price and output elasticities are heterogeneous within the same manufacturing sector across countries furthermore an output contraction due to e g demand shocks will generally have larger negative effects on gas demand than increases in natural gas prices

how reliable are simple single equation specifications of import demand this paper examines nine models of aggregate import demand for each of five countries canada germany japan united kingdom and united states in an attempt to determine which of the frequently used single equation models of import demand are appropriate an appropriate model is defined as one which generates unbiased or at least consistent and efficient elasticity estimates while models without lagged adjustments and almon lag models perform rather poorly according to these criteria models including dynamic behavior through lagged values of the dependent variable are frequently accepted results are reported regarding functional form measures of variables and structural shift economists have devoted considerable attention to the estimation of aggregate import demand elasticities because of their importance in trade theory the simplest procedure for estimating these elasticities which is consistent with economic theory is to assume that the elasticity of supply of imports is infinitely elastic and to estimate

liberalizing the energy markets of western europe a computable equilibrium model approach using a computable equilibrium model the short run effects of a radical liberalization of the west european natural gas and electricity markets are examined in each model country oil gas coal and electricity are produced traded and consumed there are world markets for oil and coal and well integrated competitive markets for gas and electricity in western europe gas and electricity are transported and traded across markets under the assumption of ideal third party access regimes for transportation and limited capacities in the transportation networks it is found that relative to the data year 1996 radical liberalization reduces the average end user price of natural gas by around 20 and the average end user price of electricity by around 50 the supply of electricity increases by around 20 mainly due to increased coal power production after such liberalization coal power emerges with the largest market share of electricity production in western europe

import demand with rational expectations estimates for bauxite cocoa coffee and petroleum abstrac t we offer a method for establishing the distributed lag structure in import demand models a priori we consider a firm which imports raw materials in a world of uncertainty traditional considerations of adjustment and inventory holding costs lead to a forward looking import decision rule linear rational expectations modelling allows us to transform the forward looking rule into a finite distributed lag specification while the resulting model is similar in form to earlier empirical models it is not subject to the lucas critique the model is fitted to u s data over the period 1954 1980

determinants of international trade flows this paper models and estimates import demand and demand for export functions for 19 industrial countries although primary emphasis is placed on the period of generalized floating exchange rates 1972 through 1980 estimates are also provided for the fixed exchange rate years 1957 1970 thus making possible a comparison between the two eras aside from the conventional income and price variables the paper assesses the effect of variations in the exchange rate and in the expected exchange rate on real trade flows additionally it estimates an unrestricted lag structure of the effect of price and exchange rate variations on imports

the effects of strategic and economic interdependence on international conflict across levels of analysis this study develops a social network analytic approach to conceptualize and measure interdependence across levels of analysis this framework contains several innovations first it integrates sensitivity interdependence the effects of changes in one state on other states with vulnerability interdependence the opportunity costs of breaking a relationship second it measures interdependence at different levels of analysis and across multiple relationships third it integrates multiple dimensions of interdependence into a single measure i derive hypotheses from the realist and liberal paradigms regarding the effects of strategic and economic interdependence on monadic dyadic and systemic conflict these hypotheses are tested via data on alliances military capability and trade the findings provide robust support to the expectations of the liberal paradigm regarding the effects of strategic and economic interdependence on conflict on the other hand the expectations of the realist paradigm are not supported i discuss the theoretical and empirical implications of this approach

long run price elasticities and the marshall lerner condition revisited abstract in estimating trade elasticities most previous researchers employed nonstationary data and ols or 2sls method with new developments in the literature this paper uses stationary data and johansen s cointegration analysis to provide new trade elasticities for almost 30 countries

brazil us commodity trade and the j curve currency devaluation or depreciation is said to temporarily worsen a country s trade balance and improve it later an effect that is called the j curve previous research that tested the j curve for brazil used the country s aggregate trade flows with the rest of the world and did not find support for the phenomenon in this article we consider the trade flows between brazil and a major trading partner the united states disaggregating their trade flows by commodity we then test the empirical validity of the j curve for each of the 92 industries that trade between the two countries we find support for the phenomenon in 31 industries therefore disaggregation by industry seems to yield some support for the phenomenon

on the structural stability of trade equations the case of japan abstract this study examines the stability of japanese trade equations over the period 1976 1993 it finds evidence of parameter nondashconstancy in equations for both total and bilateral us japan trade in most of the equations the instability can be traced to changes in specific parameter estimates in the mid 1980s in these cases failure to account for the parameter changes leads to an underestimation of actual trade flows that in some instances is significant by implication standard trade equations estimated from historical data may not be applicable to the analysis of japanese trade in the late 1980s and beyond

intertemporal substitution imports and the permanent income model abstract we examine the importance of intertemporal substitution in u s import consumption using a model of permanent income that allows for random preference shocks and additive separability the latter feature allows us to take two estimation approaches in the first approach we show that there is a cointegrating restriction imposed by the first order conditions of the model which allows us to estimate the intertemporal elasticity of imported and domestic goods consumption in the second approach we estimate the euler equations using generalized method of moments this approach however requires us to place some restrictive assumptions on the model that are not required for the first estimation approach thus the two different approaches allow an assessment of the severity of these restrictive assumptions which are often imposed in the literature

smuggling and the black market for foreign exchange this paper develops a model of the black market for foreign exchange in which black market currency is demanded and supplied by firms engaged in smuggling it is demonstrated that quotas or foreign exchange rationing are not necessary to induce the coexistence of legal and black foreign exchange markets variants of the model analyze the implications of capital flight unbalanced trade quotas foreign exchange licensing and economies with more than two goods

a complementarity model for the european natural gas market abstract in this paper we present a detailed and comprehensive complementarity model for computing market equilibrium values in the european natural gas system market players include producers and their marketing arms which we call traders pipeline and storage operators marketers lng liquefiers regasifiers tankers and three end use consumption sectors the economic behavior of producers traders pipeline and storage operators liquefiers and regasifiers is modeled via optimization problems whose karush kuhn tucker kkt optimality conditions in combination with market clearing conditions form the complementarity system the lng tankers marketers and consumption sectors are modeled implicitly via appropriate cost functions aggregate demand curves and ex post calculations respectively the model is run on several case studies that highlight its capabilities including a simulation of a disruption of russian supplies via ukraine

trade liberalisation the peso and mexico s commodity trade flows with the united states abstract we assess the effects of real peso devaluations as well as the effects of gatt and nafta on mexico s in payments and out payments with the united states for 102 industries we find that relatively few trade flows are sensitive to changes in the real exchange rate probably due to production sharing and intra industry trade but devaluations affect mexican imports more than exports trade liberalisation has had a larger impact particularly on imports of intermediate goods and exports of certain manufactures many affected export industries are ones that have previously been shown to have economies of scale

how sensitive are malaysia s bilateral trade flows to depreciation in an attempt to assess the impact of currency depreciation on the trade balance recent studies are employing disaggregated trade data to avoid aggregation bias however since import and export prices are not available at disaggregated level recent studies are using export and import values rather than their volumes so that they can establish direct relation between inpayments and the exchange rate as well as between outpayments and the exchange rate this study explores the experience of malaysia bilateral inpayments and outpayments models are estimated between malaysia and her 14 trading partners using quarterly data and bound testing approach to cointegration the results show that while real depreciation of the ringgit has short run effects in the long run it increases malaysia s inpayments from only five trading partners

does increased extraction of natural gas reduce carbon emissions without an international climate agreement extraction of more natural gas could reduce emissions of co2 as more clean natural gas may drive out dirty coal and oil using a computable equilibrium model for the western european electricity and natural gas markets we examine whether increased extraction of natural gas in norway reduces global emissions of co2 we find that both in the short run and in the long run total emissions are reduced if the additional quantity of natural gas is used in gas power production in norway if instead the additional quantity is exported directly total emissions increase both in the short run and in the long run however if modest co2 taxes are imposed increased extraction of natural gas will reduce co2 emissions also when the additional natural gas is exported directed

trade and price variation in an integrated european power market this paper examines the potential gains in terms of increased social surplus from integrating the power markets in europe and assesses the scope for free seasonal and diurnal trade in a setting of third party access tpa we construct an equilibrium model at the level of the wholesale markets taking account of the existing power generating infrastructure of varying flexibility as well as the existing transmission network interconnecting the countries involved the model indicates an overall gain from integrating the power markets electricity prices are substantially reduced for all regions involved thus implying a significant redistribution of income from producers to consumers trade flourishes with regions establishing themselves as either pure exporters pure importers or as intermediaries acting as transit countries

consumer electricity and gas prices across australian capital cities structural breaks effects of policy reforms and interstate differences abstract we detect and analyze the most significant structural changes in the quarterly growth rate of consumer electricity and gas prices in australia and estimate their corresponding seasonal effects to do so we apply the general modelling framework of the bai perron breaking regression to all available quarterly data for capital cities individually and australia as a whole 1989q3 2017q2 retail energy prices in most australian states were deregulated in the 2000s we find that increases in average quarterly growth rates of electricity and gas prices consistently occurred in the third september quarter and find very few instances of increases in any other quarters of the year in the post deregulation period price increases are significantly higher than in the pre deregulation era results for some capital cities are stark in perth third quarter growth in electricity prices has been five times higher after the structural break in australia as a whole third quarter growth in gas prices has been three times higher after the structural break we discuss several possible explanations for energy price rises in the period since deregulation

impacts of trade liberalisation commitments on the vietnamese economy a cge approach this article quantifies the economic effects of tariff reduction following vietnam s wto accession it differs from previous studies in several aspects first the model incorporates non standard features of the vietnamese economy e g changes in the domestic tax system second the model divides vietnamese households into 10 groups allowing for the assessment of household welfare and income distribution third the model has been run employing the most up to date database available the major findings are summarised as follows first vietnam as a whole would benefit from trade liberalisation second the overall gain would be accompanied by a redistribution of income and a moderate increase in inequality between the rich and the poor third concerning sectoral output export oriented sectors sectors with large shares of input in total imports and those with increased domestic demands are likely to expand whereas in contrast domestic oriented sectors are likely to contract measures to increase labour mobility target disadvantaged groups and areas and further liberalise service sectors are recommended as the recipe for effective utilisation of integration as well as a more equitable pattern of growth

water on fire gains from electricity trade in light of the ongoing liberalization of electricity trade in the nordic countries and perhaps in northern europe we argue that gains from electricity trade may be different from those traditionally associated with comparative advantages and economies of scale in particular we consider gains arising from the exploitation of technological complementarities between hydro and thermal systems our theoretical framework highlights essential features of the two systems and allows for an analysis of effects of trade we study three trading regimes which may arise either endogenously or because of trade regulations day night power exchange seasonal energy banking and unbalanced trade the analysis suggests that gradual trade liberalization may be costly

the effects on competitiveness of coordinated versus unilateral fiscal policies reducing ghg emissions in the eu an assessment of a 10 reduction by 2010 using the e3me model abstract international competitiveness effects from coordinated and uncoordinated multilateral policies to reduce co 2 emissions from 11 member states of the eu by 2010 are compared with those from unilateral policies to achieve a 10 cut in each member state alone the paper presents the results from four projections using a large scale integrated regionalised e3 model of the eu estimated on time series cross section data 1968 93 with international trade treated as between each member state and a european transport and distribution network the 10 reduction is achieved by additional excise duties incremented every year 1999 to 2010 according to the carbon contents of fuels with special with special treatment of electricity taxed on outputs not inputs with revenues recycled via reductions in employers social security contributions multilateral coordinated policies require a common tax rate of 156 ecu per tonne carbon 1999 prices which rises to an average of 165 ecu per tonne with a wide range between regions when policies are uncoordinated all the tax shift projections show double dividends for emission reduction and employment gain for all member states unilateral policies do not show much carbon leakage but they show smaller gains for output and employment effects for price competitiveness appear to be small and mixed with serious losses appearing only for the netherlands and for metals and chemicals especially for unilateral action

adjustment costs and import demand behavior evidence from canada and the united states abstract in this paper we examine whether adjustment costs are a significant source of the observed sluggish adjustment of canadian and us import demand we use a simple model of a utility maximizing domestic consumer under the assumption of integrated forcing variables to examine the importance of adjustment costs this formulation of the problem allows us to exploit the recently developed theory of cointegration to estimate the structural parameters of the model using a two step methodology moreover the formulation incorporates an element of forward looking behaviour into the decision process a feature that is important if one assumes adjustment costs are a significant source of persistence in import demand adjustment the empirical results from a euler equation imply that adjustment costs in canada and the united states are important

external imbalances in the eurozone the paper examines the extent to which current account imbalances of euro area countries are related to intra euro area factors and to external trade shocks we argue that the traditional explanations for the rising imbalances are correct but are incomplete we uncover a large impact of declines in export competitiveness and asymmetric trade developments vis a vis the rest of the world x96 in particular vis a vis china central and eastern europe and oil exporters x96 on the external balance of euro area debtor countries while current account imbalances of euro area deficit countries vis a vis the rest of the world increased they were financed mostly by intra euro area capital inflows in particular by the purchase of government and financial institutions securities and cross border interbank lending which permitted external imbalances to grow over time ruo chen gian maria milesi ferretti and thierry tressel

the adjustment of canadian import demand to changes in income prices and exchange rates the paper provides estimates of the sensitivity of canadian import demand to changes in income prices and exchange rates the model specification allows for the con sideration of long run elasticities as well as the dynamics of short run adjustment of imports to changes in these variables the estimated long run elasticities obtained are similar to those in previous studies it is also shown that canadian imports react quickly to changes in either foreign or domestic prices but that the reaction to changes in exchange rates is much slower

effects of income growth and tariffs on the world salmon market the effects of income growth and tariffs on salmon prices production and trade flows are analysed using total elasticities derived from an equilibrium displacement model of the world salmon market results suggest the total income elasticity in world trade for salmon is about one which means imports worldwide will grow at about the same pace as world income however owing in part to policies that restrict supply response not all exporters will share evenly in this growth with uk producers benefiting the most and norwegian producers the least within importing countries imports are more responsive to income growth than is domestic production which means protectionist pressures are apt to increase with affluence us tariffs on imports from norway and chile are counterproductive in that they reduce world imports with little effect on the us price norway s feed quota reduces the efficacy of us tariffs makes imports less responsive to income and increases price volatility hence quota elimination m

trade policy making in a model of legislative bargaining in democracies trade policy is the result of interactions among many agents with different agendas in accordance with this observation we construct a dynamic model of legislative trade policy making in the realm of distributive politics an economy consists of different sectors each of which is concentrated in one or more electoral districts each district is represented by a legislator in the congress legislative process is modeled as a multilateral sequential bargaining game a la baron and ferejohn 1989 some surprising results emerge bargaining can be welfare worsening for all participants legislators may vote for bills that make their constituents worse off identical industries will receive very different levels of tariff the results pose a challenge to empirical work since equilibrium trade policy is a function not only of economic fundamentals but also of political variables at the time of congressional negotiations some of them random realizations of mixed bargaining strategies

us bilateral trade equations forecasts and structural stability in this paper actual recent us trade values are compared with out of sample forecasts using a standard specification for real bilateral trade value equations though fairly accurate on average there are large bilateral errors a battery of coefficient stability tests indicates significant instability more often for imports over the forecast period and more often for exports over the latter part of the estimation period thus standard bilateral trade equations appear to violate the basic regression assumption of stability and may be of little use for forecasting

bilateral trade elasticities this paper estimates income and price elasticities for bilateral world trade in addition to testing the properties of the error terms the dynamic specification and the assumption of parameter constancy the analysis presents the first application of the bank spectrum estimator to bilateral trade flows for all countries the paper finds that bilateral trade elasticities exhibit enough of a dispersion to suggest that the direction of trade is sensitive to changes in income and prices using the bilateral elasticities as raw data the analysis obtains the associated multilateral estimates and finds that they are both consistent with the literature and suitable to addressing questions involving multilateral trade but the evidence also reveals that sole reliance on multilateral elasticities conceals valuable information for both policy applications and empirical analyses of international trade copyright 1990 by mit press

u s bilateral trade balances and the dollar abstract u s bilateral export and import values with seven large trading partners are tested for real exchange rate effects over 1975 1985 the results suggest that dollar devaluation would have the most favorable impact on the u s trade balance in the case of japan and the least favorable in the case of canada

technology shocks and employment recent empirical work has suggested that in response to a positive technology shock employment shows a persistent decline we show that the standard open economy flexible price model can generate a negative response of employment to a positive technology shock and can also match the negative conditional correlation between productivity and employment quite well if trade elasticities are low while the model also has good overall properties it fails to generate sufficient procyclicality in employment this finding indicates that the rbc model faces a tension between accounting for the negative response of employment to technology shocks and simultaneously maintaining that technology shocks are the major source of business cycle fluctuations

nominal and real effective exchange rates of middle eastern countries and their trade performance indexes of real and nominal effective exchange rates that are published by the imf are mostly for industrial countries none of the middle eastern countries have received any attention on this regard this paper tries to close the gap by constructing such indexes for 11 middle eastern countries over 1971 i 1994 iv period as an application long run response of their trade balance to devaluation is also investigated

evaluating dispatchability features in competitive bidding in power systems competitive bidding for electric generating capacity is beginning to emphasize dispatchability the authors examine various aspects of the evaluation problem facing electric utilities recent private power contracts are used to illustrate the range and limits upon flexibility that are being offered only detailed production simulation models can capture the cost implications of the features being offered the value of the dispatchability was found to increase with the variable cost of operation the most important cost found was associated with projects offering only limited curtailment procedures for incorporating subtle dispatch effects in a broader evaluation framework are identified

beyond kyoto backstop technologies and endogenous prices on co2 permits and fossil fuels this paper analyses the markets for fossil fuels given that the limits the kyoto protocol sets on co2 emissions from annex b countries extend beyond 2008 2012 a forward looking model with endogenous prices for fossil fuels is applied under different assumptions concerning the technological progress for a carbon free backstop technology both the time profile of the international permit price needed for the kyoto forever targets as well as the implications through reduced demand and lower producer prices for fossil fuels are calculated the permit price has to rise at least up to 2030 in order to fulfil the emission targets from then on the necessary permit price shows different future developments dependent on when the backstop technology starts to replace oil since changes in the availability of the backstop technology shift the time profile of the permit price the loss of petroleum wealth for oil and gas producers varies between the scenarios but is never more than 20 findings indicate that the
