natural resources national income and economic growth in africa abstract because standard measures of aggregate income such as gross domestic product gdp do not account for natural resource depletion their use as gauges of economic performance tends to exaggerate the benefits of resource extraction accounting for natural resource depletion in 18 african countries indicates different patterns of growth than those suggested by gdp figures use of the revised measures in analyses of the link between exports and growth suggests that export expansion may generate increases in measured gdp without stimulating increased production in contrast real exchange rate alignment is correlated with growth in both conventional gdp and the revised accounts

the contribution of tourism development to economic growth in the korean economy abstract this study investigates the causal relations between tourism growth and economic expansion for the korean economy by using engle and granger two stage approach and a bivariate vector autoregression var model two principle results emerge from this study first the results of a cointegration test indicate that there is no long run equilibrium relation between two series second the outcomes of granger causality test imply the one way causal relationship of economic driven tourism growth the hypothesis of tourism led economic growth is not held in the korean economy this consequence is supported by testing the sensitivity of causality test under different lag selections along with the optimal lag

spatial sustainability trade and indicators an evaluation of the ecological footprint the search for frameworks and indicators of sustainable development has taken a prominent place in this journal however some specific aspects have received little or no attention notably the spatial dimension and the role of international trade in indicator development moreover many sustainable development indicators comprise implicit valuations weighting schemes and policy objectives which are insufficiently recognised as such this contribution tries to highlight these issues by means of a review of a recently proposed indicator for ecological economic analysis namely the ecological footprint that has been developed by wackernagel and rees its concept and calculation procedure are criticised on a number of points and it is concluded that the ecological footprint is not the comprehensive and transparent planning tool as is often assumed in explaining our position we will argue that spatial sustainability and regional sustainable development have not been precisely discussed so far neither in the literature on trade and environment nor in that on sustainable development we will defend the view that trade can contribute positively and negatively to environmental unsustainability consequently indicators and models are needed that allow for analysing interactions and trade offs between such opposite effects 1999 elsevier science b v all rights reserved

optimal selection of process mean for a stochastic inventory model abstract it is very common to assume deterministic demand in the literature of integrated targeting inventory models however if variability in demand is high there may be significant disruptions from using the deterministic solution in probabilistic environment thus the model would not be applicable to real world situations and adjustment must be made the purpose of this paper is to develop a model for integrated targeting inventory problem when the demand is a random variable in particular the proposed model jointly determines the optimal process mean lot size and reorder point in q r continuous review model in order to investigate the effect of uncertainty in demand the proposed model is compared with three baseline cases the first of which considers a hierarchical model where the producer determines the process mean and lot sizing decisions separately this hierarchical model is used to show the effect of integrating the process targeting with production inventory decisions another baseline case is the deterministic demand case which is used to show the effect of variation in demand on the optimal solution the last baseline case is for the situation where the variation in the filling amount is negligible this case demonstrates the sensitivity of the total cost with respect to the variation in the process output also a procedure is developed to determine the optimal solution for the proposed models empirical results show that ignoring randomness in the demand pattern leads to underestimating the expected total cost moreover the results indicate that performance of a process can be improved significantly by reducing its variation

inventory model with stock level dependent demand rate and variable holding cost inventory models in which the demand rate depends on the inventory level are based on the common real life observation that greater product availability tends to stimulate more sales previous models incorporating inventory level dependent demand rate assume that the holding cost is constant for the entire inventory cycle this paper considers the inventory policy for an item with a stock level dependent demand rate and a storage time dependent holding cost the holding cost per unit of the item per unit time is assumed to be an increasing function of the time spent in storage two time dependent holding cost step functions are considered retroactive holding cost increase and incremental holding cost increase procedures are developed for determining the optimal order quantity and the optimal cycle time for both cost structures

exports and economic growth evidence from 19th century europe abstract cointegration and granger causality tests on data for six european countries from around the middle of the 19th century to 1913 show that exports and gnp were cointegrated and granger causally related with export led growth in italy norway and sweden

equilibrium pollution taxes in open economies with imperfect competition abstract this paper argues that imperfect competition in global markets creates a strategic interaction between governments that can lead to the inefficient distortion of pollution taxes this distortion can be decomposed into a rent capture effect and a pollution shifting effect the rent capture effect lowers equilibrium taxes as each country attempts to gain a competitive advantage over its trading partner and thereby capture foreign rent through net exports the pollution shifting effect raises equilibrium taxes as each country attempts to transfer production and its associated pollution to the other country this effect vanishes if pollution is perfectly transboundary because shifted pollution causes as much damage to the domestic environment as does domestic pollution the net effect on symmetric equilibrium taxes is negative except in the special case of perfect competition with no transboundary pollution in this case the two effects are mutually offsetting and the nash equilibrium is efficient when pollution is at least partially transboundary there also arises the usual transboundary externality and this reinforces the negative net strategic effect giving rise to equilibrium taxes that are lower than what is globally efficient

learning and the time interdependence of costa rican exports abstract exports may enhance learning through production induced learning by doing learning to export by doing and flows of information from customers we provide evidence on the learning effects of export destination for costa rica for 1955 through 1980 we examine granger causality results and export trends to determine relationships between exports to the central american common market cacm the rest of the south and the north increasing exports to the cacm appear to promote learning in machinery leather and intermediate manufactures we also find that the cacm redirects some exports away from northern markets probably with damaging consequences

vector autoregression cointegration and causality testing for causes of the british industrial revolution the existence timing and possible causes of the british industrial revolution are considered by investigating the time series properties of industrial production and various explanatory variables utilising two types of robust cointegration based causality tests we argue that domestic forces notably technological progress shaped the industrial revolution whereas overseas trade expansion was mainly a consequence of industrial growth results from granger type var tests are contrasted with those of toda and phillips working paper 91 07 university of western australia 1991b where the latter manifest some of the potential problems raised by the authors when applied to a data set of this type an understanding of the possible causes of the first industrial revolution may shed more general light on the forces promoting industrialization and growth to the extent that the first industrial revolution offers a template exports appear not to provide a simple pathway to industrialization

are economists traditional trade policy views still valid recent analysis of trade policies under imperfectly competitive market conditions as well as in situations where trade in high technology products is important have raised doubts whether economists should continue their traditional opposition to trade taxes and subsidies this paper evaluates the new theoretical arguments for interventionist trade policies by comparing them with the traditional arguments for and against free trade investigating the empirical evidence supporting the conditions assumed in the new models appraising the realism of the behavior assumptions of these models and the sensitivity of their conclusions to changes in these assumptions and considering the political economy implications of these conclusions the general conclusion is that there are serious practical difficulties with the interventionist arguments of the new trade theorists as they themselves recognize just as there are with such traditional arguments for trade intervention as the terms of trade case for protection however the new industrial organization approach to trade theory has already provided valuable insights into trade behavior in international markets and promises to provide many more as more realistic behavior models are developed this abstract was borrowed from another version of this item

export led growth and structural change evidence from malaysia many studies have tried to establish the causal link between export expansion and economic growth this contribution is to recognize that structural changes will change the sources of growth and this will affect the export growth relationship a country case study approach is used focusing on malaysia a country with one of the world s highest sustained growth rates and a long history of commodity trade we use var analysis of malaysian quarterly trade and gdp growth from 1965 to 1996 trade data are disaggregated into primary and manufactures exports and causality tests are applied to the entire period as well as two subperiods 150 the 1965 1501980 period when policy emphasis was on import substitution and the 1981 1501996 period when policies favoured export led growth statistical tests confirm export led growth for the full period and for the period to 1980 but tests on the 1981 1501996 period show growth causing exports primary exports had a stronger direct impact on economic growth than manufactu

joint optimal determination of process mean production quantity pricing and market segmentation with demand leakage abstract the selection of an optimal process mean is an important problem in production planning and quality control research most of the previous studies in the field have analyzed the problem for a fixed exogenous price however in many realistic situations besides product quality product pricing is a paramount factor that determines the purchase behavior in the market in the experts opinion an integrated framework that incorporates pricing as a decision tool could significantly improve a firm s profitability most of the manufacturing firms yield products with distinguishable characteristics and therefore it is desirable to sell these products on the market at differentiated prices whereas the market segmentation achieved using differentiated prices is often imperfect a firm may experience demand leakages thus an optimal price decision must incorporate demand leakage effects for the firm to benefit from its differentiated pricing strategy in this paper these issues are addressed by proposing an optimal framework for joint determination of process mean pricing production quantity and market segmentation using differentiated pricing this research discusses a production process that manufactures multi class grade products based on their quality attribute the products are sold in primary and secondary market at differentiated prices while experiencing demand leakages the nonconforming items are reworked at an additional cost mathematical models are developed to address the problem under both price dependent deterministic and stochastic demand situations we propose a harmony search meta heuristic for solving the models a numerical experimentation is presented to study the significance of the proposed integrated decision framework

exports and growth is the export led growth hypothesis valid for provincial economies this paper re examines the export led growth hypothesis using provincial data unlike other studies that concentrate on country level data this study investigates the validity of the hypothesis for four largest provinces in korea seoul kyunggee kyungnam and pusan the causal implication of the export led growth hypothesis is generally supported for all provinces in the sample the framework of analysis is two and four variable autoregressive models that include provincial exports provincial output terms of trade and national output shocks granger causal orderings from exports to output growth are generally supported in bivariate causal models in multivariate models variance decompositions and impulse response functions further indicate that export growth has a significant impact on output growth for all provinces although a feedback effect from output to export growth appears in seoul and the kyungnam province

a dynamic migration model with uncertainty we study a dynamic version of the harris todaro migration model where a finite population of infinitely lived bayesian agents choose consumption and migration decision rules as a function of their histories the agents do not know the production functions in the two sectors and learn about them through wage draws that they receive from the stochastic production functions the government knows the true production functions but is uninformed about the agents beliefs and the actual wage draws they observe the government maximizes its welfare function using wage subsidies in the two sectors and a migration tax we solve the agents dynamic programming problem and then use the solution to solve the government s dynamic programming problem we study the effects of government policies on the population distribution and illustrate the model by numerically solving a particular parametric example

exports investment efficiency and economic growth in ldc an empirical investigation this study seeks to analyse the relationship between exports and growth for 19 less developed countries it utilizes multivariate causality analysis based on the error correction model to address several important hypotheses the results indicate that when exports have a causal influence in the development process that in general this is the result of their effect on both efficiency and accumulation in addition improvements in output and capital accumulation in an economy seem to have just as much of an influence on exports as exports have on output and capital accumulation finally the growth process in east asia seems to be quite different from that in southeast asia

relationship between agricultural growth and farm imports in ldcs a sims causality test based on 35 countries abstract previous empirical studies on the relationship between agricultural growth and farm imports in the ldcs suffer from serious methodological defects which to some extent may invalidate their results and interpretations this study used sims causality test to examine interactions between agricultural output and agricultural imports for 35 ldcs individually it was found that there was no causality from agricultural output to agricultural imports for a majority of countries under study for countries where agricultural growth did have a causal effect on agricultural imports the effect was positive in some countries and negative in others

causality between export growth and industrial development empirical evidence from the nics a comment abstract in a recent article chow 1987 argued that his empirical evidence supports the hypothesis that export growth causes industrial development in this comment i point out several serious shortcomings of chow s analysis

export instability and the domestic economy questions of causality the conventional view concerning the impact of export instability on the domestic economies of developing countries is one of pessimism export instability is thought to adversely affect the short run stability and longer run growth of income empirical evidence on these matters is however inconclusive this article applies a granger sims reduced form approach to examining whether export instability generates short run instability in domestic income for each of a sample of 20 trade dependent countries the results obtained strongly support the contention that export instability induces short run macroeconomic instability

trade and industrial policy under oligopoly comment recently in this journal eaton and grossman 1986 built a model characterized by a home firm that sells abroad with one foreign competitor they determined what the home government tax policy should be under different assumptions about oligopoly behavior and the other country s tax schedule a problem occurs when they write that the reaction function of the foreign firm is independent of the tax rate on the home firm while this statement is true for the cournot and bertrand cases that they analyze in the consistent conjectures case the foreign firm s reaction function must take into consideration the slope of the reaction function of the home firm which is dependent upon the tax rate as we show this invalidates their proposition 3 which states that the optimal home tax in the consistent conjectures case is zero in this comment we show by example that the optimal tax is not necessarily zero

environment versus growth a criticism of degrowth and a plea for a growth in recent debates on environmental problems and policies the strategy of degrowth has appeared as an alternative to the paradigm of economic growth this new notion is critically evaluated by considering five common interpretations of it one conclusion is that these multiple interpretations make it an ambiguous and rather confusing concept another is that degrowth may not be an effective let alone an efficient strategy to reduce environmental pressure it is subsequently argued that a growth i e being indifferent about growth is a more logical social aim to substitute for the current goal of economic growth given that gdp per capita is a very imperfect indicator of social welfare in addition focusing ex ante on public policy is considered to be a strategy which ultimately is more likely to obtain the necessary democratic political support than an ex ante explicit degrowth strategy in line with this a policy package is proposed which consists of six elements some of which relate to concerns raised by degrowth supporters

is the export led growth hypothesis valid for australia the relationship between exports and output is examined using australian annual data over the period 1900 1993 cointegration and causality testing fails to detect the existence of a long run or short run relationship between the two variables these results are explained by restoring to the structural time series modelling approach which shows that while the output series exhibits cyclical variation the exports series does not have this property it is concluded that the export led growth hypothesis is not valid for australia

exports imports and economic growth in south korea and japan a tale of two economies this article investigates the relationship between exports imports and economic growth for south korea and japan by constructing a vector autoregression var model causality is examined between real gross domestic product gdp real exports and real imports several principal results emerge from the empirical work first the three variables are cointegrated for both countries implying that a long run steady state exists second there is evidence of bidirectional causality between imports and economic growth for both countries finally japan seems to experience export led growth while gdp growth in south korea has a negative effect on export growth these contrasting findings could result from export goods in japan exhibiting greater nonprice competitive aspects although their success fails to trigger a virtuous circle since growth fails to lead to increased exports while for south korea output growth leads to a decrease in export growth suggesting a strong domestic market

the effect of the asian financial crisis on the relationships among open macroeconomic factors for asian countries this study investigates the effect of asian financial crisis on the relationships among exchange rate volatility export import and productivity for taiwan korea malaysia and indonesia cointegration tests show no change for the long run equilibrium relationship among these variables throughout the crisis granger causality finds that some exogeneity orderings alter from pre to post crisis periods for the countries considered impulse response functions irs for the pre crisis period demonstrate the primary importance of productivity then second importance of export for the post crisis period oscillatory paths around zero of the irs imply an ambiguous finding for the direction of effect and relative exogeneity among variables studied the variance decompositions in export for taiwan korea and malaysia and in productivity for malaysia and indonesia did not change from the pre crisis to the post crisis era however most of the rest of the forecast error variances in variables were decomposed in

the long run impact of foreign shocks to the austrian economy an analysis at a sectoral level this paper investigates the long run impact of foreign shocks on the austrian economy which is an example of a small open economy with a fixed echange rate regime the analysis is done in a multisectoral vector autoregression framework foreign shocks involve inovations in gnp of european oecd countries oil prices effective echange rate and interest rates sectoral responses appear to be very different in particular shocks to european oecd gnp have a high long run impact on sectoral output especially in export dependent sectors this supports the hypothesis of export led growth

determining the optimal target for a process with multiple markets and variable holding costs abstract the determination of the quality target for a manufacturing process represents an intricate and fiscally vital decision this study examines methods for process target optimization in industries where several grades of consumer specifications and hence several quality grades of products may be sold within the same market in such situations manufacturers may hold goods that have been rejected by one customer to sell the same goods to another consumer in the same market at a later date the expected profit function for such firms must consider the holding costs as well as the profits associated with this sales strategy this study provides a conceptual and mathematical overview of such situations a method for identifying the optimal process target that reflects holding costs is presented and illustrated in the context of the steel galvanization industry

the validity of the elg hypothesis in the mena region cointegration and error correction model analysis the export led growth elg hypothesis is examined for nine middle east and north africa mena countries in three variable vector autoregressive and error correction models when considering total exports the results reject the elg hypothesis in almost all of these countries when only manufactured exports are examined no support is found for elg in countries with relatively low shares of manufactured exports in total merchandise exports but strong support in countries with relatively high shares these findings suggest that promoting exports may contribute to economic growth only after a certain threshold of manufactured exports has been reached

growth and exchange rate volatility a panel data analysis the aim of this article is to assess the role of real exchange rate rer volatility on long run economic growth for a set of 82 advanced and emerging economies using a panel data set ranging from 1970 to 2009 with an accurate measure for exchange rate volatility the results for the two step system generalized method of moments gmm panel growth models show that a more less volatile rer has a significant negative positive impact on economic growth the results are also robust for different model specifications

foreign growth and domestic performance in a small open economy abstract in this paper we develop a small open economy model of trade with endogenous growth induced by human capital accumulation to analyze the effects of foreign growth on the domestic growth performance stronger foreign growth has the potential to increase domestic growth through a change in the terms of trade for this to happen the domestic attitude toward saving as indicated by the intertemporal elasticity of substitution plays a crucial role for economies with sufficiently thrifty consumers changes in the terms of trade generate funds for domestic investment thereby generating enhanced long term growth if however domestic consumers are less prone to thriftiness foreign growth may lead to lower domestic output growth this result suggests that foreign growth is not necessarily a substitute for a weak domestic attitude toward saving

an empirical investigation of the causal relationship between openness and economic growth in china this study investigates the causal relationship between openness and economic growth in china the integration and cointegration properties of the data are analysed and the models of granger sims geweke and hsiao are used to identify a bi directional causal relationship between gnp and exports plus imports this bi directional causation is consistent with china s development strategy of protected export promotion

the economic case for international labour standards this paper explores the economic case for international labour standards granting workers rights of free association and collective bargaining confers both static and dynamic economic efficiencies static efficiencies refer to one time gains from improvements in economic practice dynamic efficiencies refer to gains from improvements to the growth path resulting from a shift away from a low road development path to a high road path these efficiencies raise wages employment and output in developing countries and they can also benefit workers in developed countries labour standards are an institutional mechanism for raising the quality of growth in both developing and developed countries in this sense they are a win win institution

hyper individualism and ultrasociality in a veblenian framework abstract in a series of articles gowdy and krall 2013 2016a 2016b framed the process of cumulative social change as a codevelopment of hyper individualism and ultrasociality they argue that at the macro level the global economic system behaves as a superorganism which has co opted human beings cooperative propensity in order to continuously expand its surplus value appropriating an ever larger share of natural resources at the micro level the neoliberal era has legitimized increased competition among individuals and has led to a hyper focus on the maximization of individual consumption in their social context individuals appear to be largely oblivious or dismissive of the growing superorganism as is evidenced by public unwillingness to address situations of global environmental stress in the context of veblen s evolutionary thinking this paper comments on gowdy and krall s articles by discussing two potential venues to tame the superorganism de growth and post nationalism it is argued that the former may be a solution only as a result of a severe ecological collapse scenario thus if the social desire to modify the superorganism exists it will have a greater chance to succeed as a post national project that would provide a structural scaffolding to place the superorganism within human control

tacit bargaining and arms control astate bargains tacitly with another state when it attempts to manipulate the latter s policy choices through its behavior rather than by relying on formal or informal diplomatic exchanges the process is tacit because actions rather than rhetoric constitute the critical medium of communication it is bargaining and not coercion because the actions are aimed at influencing an outcome that can only be achieved through some measure of joint voluntary behavior obviously states rarely rely on either purely tacit or purely formal negotiation however the theory of tacit bargaining does not become totally inapplicable when there is verbal or written communication between the principals it simply becomes increasingly relevant as states rely more on actions than on conventional negotiation examples of tacit bargaining are plentiful in international relations a retaliatory tariff is announced in response to trade barriers a state at war refrains from using chemical weapons or from bombing nonmilitary targets in the hope that its opponent will behave similarly an austerity program is implemented by a financially troubled government in order to convince foreign banks that they should continue to extend credit

cointegration causality and export led growth in mexico 1895 1992 abstract cointegration and granger causality tests show that real exports and real gdp in mexico over 1895 1992 were cointegrated and there was a significant and positive granger causal relationship running from exports to economic growth

up the average cost curve inefficient entry and the new protectionism abstract a two country model is developed in which each country produces one good with increasing returns the goods being perfect or imperfect substitutes with cournot nash behavior and free entry certain restrictive trade policies have effects opposite to their favorable effect under noentry assumptions import tariffs and export subsidies lead to inefficient entry that raises rather than decreases the average production cost of and price charge by the domestic industry with negative welfare consequences we argue that these predictions of our model are closely consistent with extensive canadian data on entry exit and firms responses to trade liberalization

causality between exports and economic growth abstract this paper utilizes granger causality tests in investigating the relationship between exports and national income from a consistent data set for 47 developing countries in africa new empirical results as well as suggestions for future research are presented

causality between export growth and industrial development empirial evidence from the nics abstract this paper investigates the causal relationship between export growth and industrial development in eight newly industrializing countries nics results of sims causality test show that for most of the nics there is a strong bidirectional causality between the growth of exports and industrial development these findings support the export led growth strategy in that expansion in exports not only promote the growth of national income but also lead to structural transformation of the developing countries

exports growth and causality in ldcs abstract using akaike s optimal lag criterion in a granger causality test the causal relationship between export growth and economic growth and vice versa is re examined for 20 countries it is argued that earlier analyses which ignore optimal lags in granger or sims causality tests suffer from certain shortcomings which are overcome by the present approach the results suggest some support for the export promotion hypothesis especially in the case of well known nics and thus differ from previous applications of granger test which did not adopt an optimum lag criterion and which showed no causality from export growth to economic growth in such cases however they are inconclusive in evaluating competing hypotheses

exports export composition and growth cointegration and causality evidence for malaysia this paper comprehensively tests the export led growth elg hypothesis for malaysia for the period 1955 90 using cointegration and causality testing based on hsiao s synthesis of the granger test and akaike s minimum final prediction error criterion the results provide support for the elg hypothesis aggregate exports granger cause real gdp and non export gdp this relationship is found to be driven by manufactured exports rather than by traditional exports

exports and economic growth in industrialized countries the prima facie causal relationships between growth exports and factor inputs capital and labour are investigated in five industrialized countries germany itlay japan united kingdom and united states over the period 1960 87 by analysing a four variable vector autoregressive var model for each country our results indicate that germany and japan experienced export led growth reverse causality between exports and growth is found in the case of the us and uk while to causal relationship between exports and output is found for itlay

cointegration causality and export led growth in portugal 1865 1985 abstract this paper considers the relationship between cointegration and causality and uses tests of cointegration as pre tests for granger tests of causality such methods are utilized on portuguese data 1865 1985 where the export led growth hypothesis is rejected in favour of reverse causality

the ultrasocial origin of the anthropocene abstract the current geological epoch has been dubbed the anthropocene the age of humans we argue that the roots of the anthropocene lie in the agricultural revolution that began some 8000 years ago unique human psychological and cultural characteristics were present in our distant hunter gatherer past but in terms of the biophysical impact of our species agricultural represented an unequivocal and decisive evolutionary break with the transition to agriculture human society began to function as a superorganism functioning as a single unit designed by social natural selection to produce economic surplus where environmental conditions were permitted early human agricultural societies followed the same pattern as a few social insects and exhibited explosive population growth complex and detailed division of labor intensive resource exploitation territorial expansion and a social organization favoring the survival and growth of the supergroup over the well being of individuals within the group similar economic forces lie behind ultrasociality in social insects and humans increased productivity from the division of labor increasing returns to scale and the exploitation of stocks of productive resources exploring the evolutionary mechanisms behind ultrasociality offers insights into the growth imperative that threatens the stability of the earth s life support systems

economic growth export and external debt causality the case of african countries empirical investigation of the export driven economic growth hypothesis has provided mixed results in a bivariate causality framework the problem with such bivariate causality analysis is that there can be an omitted variable which could adversely affect the results this paper looks at the trivariate causality analysis of african countries by introducing external deby servicing as a third variable in the export economic growth analysis the results indicate that there is a feedback or bidirectional causality between external debt servicing economic growth and exports evidence of the 1983 90 subperiod is consistent with the argument that the structural adjustment programmes which were designed to remove economic distortions promote exports and encourage external debt management increased growth in the countries involved

environmental regulation in an open economy abstract environmental regulation by a large trading country affects the world price of traded commodities a series of second best environmental taxes are derived which explicitly incorporate trade effects for cases which depend on the type of externality the regulating country s commodity trade balance and the presence or absence of trade taxes in the regulated market a coordinated policy solution using both tax and tariff instruments also is derived the practical implications for domestic environmental policy making which emerge from the theoretical results are evaluated

agricultural exports and economic growth in less developed countries this article examines the contribution of agricultural exports to economic growth in less developed countries ldcs a sources of growth equation is developed from a dual economy model where agricultural and nonagricultural sectors are both divided into export and nonexport subsectors this is then estimated using panel data for 62 ldcs for 1974 1995 results provide evidence that there are significant structural differences in economic growth between low lower middle and upper income ldcs investment in the agricultural export subsector has a statistically identical impact on economic growth as investment in the nonagricultural export subsector the marginal productivities in nonexport subsectors are over 30 lower than those in respective export subsectors from a policy perspective the results suggest that export promotion policies should be balanced

export expansion and economic growth testing for cointegration and causality this paper develops a multivariate error correction model to test the causality between exports and growth in 15 asian countries 1967 91 the underlying series are tested as non stationary in levels but stationary in first differences the causal factors are cointegrated in five of these countries only causality test results indicate that export expansion causes growth in two third of these countries corrected for simultaneity between the causal factors a country with a large public sector higher level of economic development and which is less vulnerable to external economic shocks is more likely to reap the benefits of export promotion strategies the causal inferences are fairly stable over the sample period

export and production growth evidence from three major wheat exporters of australia canada and the united states this article investigates the robustness of the relationship between export and production growth for three major wheat exporters australia canada and the united states from 1966 to 2000 combining production international trade and development theories a four variable production exports producer price and imports vector autoregressive moving average varma model is developed for each country the causality results show that the hypothesis of export led development is supported by these three major players in the international wheat trade though a bi directional causality is found for canada and the usa variance decomposition and impulse response functions are employed to further investigate the effects of macroeconomic shocks

non transboundary pollution and the efficiency of international environmental co operation abstract the standard view is that situations where no transborder environmental externalities occur are most efficiently dealt with by national environmental policies rather than by international co operation though this may be the general case non coordinated national policies do not always produce the most efficient international allocation this paper presents four cases in which the allocative outcome of non coordinated domestic policy choices can be improved upon by international environmental co operation the first case refers to the use of environmental policy as a strategic trade instrument the other cases refer to the existence of discrete technologies set up costs and increasing returns to scale the form of international environmental co operation should be adapted to the situation formal international agreements between countries are characterised by high transaction costs and may not always be the most efficient form of co operation

is free trade passe abstract if there were an economist s creed it would surely contain the affirmations i understand the principle of comparative advantage and i advocate free trade yet the case for free trade is currently more in doubt than at any time since the 1817 publication of ricardo s principles of political economy and this is due to changes that have recently taken place in the theory of international trade while new developments in international trade theory may not yet be familiar to the profession at large they have been substantial and radical in the last ten years the traditional constant returns perfect competition models of international trade have been supplemented and to some extent supplanted by a new breed of models that emphasizes increasing returns and imperfect competition these new models call into doubt the extent to which actual trade can be explained by comparative advantage they also open the possibility that government intervention in trade via import restrictions export subsidies

the bounds test approach for cointegration and causality between financial development international trade and economic growth the case of cyprus this study employs the bounds test for co integration and granger causality tests to investigate the long run equilibrium relationship and the direction of causality between financial development international trade and real income growth for the cyprus economy the results of the study reveal that financial development as measured by broad money m2 international trade and real income growth are cointegrated thus a long run equilibrium relationship can be inferred among these three variables on the other hand granger causality test results suggest that in cyprus the growth in real income stimulates the growth of international trade both exports and imports and the growth of money supply furthermore growth in imports of goods and services also stimulates a growth in exports of goods and services of cyprus although this result contradicts our initial expectations it indicates the importance of capital inflows in cyprus that plays a major role in financing the investments mainly in the tourism
