a general equilibrium analysis of production subsidy in a harris todaro developing economy an application to india since 1950s india has advocated import substituting industrialization policies to promote its manufacturing sector the end result was creation of a dual economy highly favored manufacturing sector with high and rigid wages and neglected agricultural sector with low wages and poverty because of the higher wages in the manufacturing sector the rural laborers migrate to the urban sector a typical characteristic of the harris todaro developing economy realizing this crisis the indian government recently initiated policies to boost agricultural production to curb the labor migration and improve the welfare of the rural population in this study we develop a computable general equilibrium cge model for india by incorporating harris todaro economic characteristics of unemployment labor migration farm dependant population and labor intensive agriculture we use the model to analyze the effects of agricultural production subsidy policies on employment factor price output price output levels and we

china s oil use 1990 2008 abstract over the past two decades china s oil demand has risen steeply in 1990 it was only about 25 higher than that of 1978 the year economic reform was introduced by 2008 it had reached 396 0 million tons roughly four times the 1978 level making china the second largest oil user worldwide the country became a net oil importer in 1993 and between 1993 and 2008 its net import dependency a yardstick for energy security soared from 7 5 to 50 0 china s increased demand for oil has made the country a global energy player of critical importance although the literature on the global implications of china s oil use has proliferated relatively few studies have attempted to examine how china uses oil hence this study covers every oil consuming facility and sector in china exploring the patterns of and factors involved in oil demand by power plants oil refineries heat plants and gas works and industrial transport agricultural household and commercial sectors it concludes that in virtually all sectors in china oil demand will grow with transport and industry leading the way

the economics of export performance requirements this paper analyzes the resource allocation and welfare effects of export performance requirements imposed on foreign investors it argues that a satisfactory analysis must consider the presence of tariff distortions and oligopolistic behavior in host country markets these create a second best environment in which an evaluation of the welfare effects of such requirements is no longer straightforward it is concluded that export requirements can improve home welfare by reducing payments to foreign capital reducing the output of commodities which are being overproduced and shifting profits toward domestically owned firms

exploring the core factors and its dynamic effects on oil price an application on path analysis and bvar tvp model abstract as the uncertainty of oil price increases impacts of the influential factors on oil price vary over time it is of great importance to explore the core factors and its time varying influence on oil price in view of this based on the path analysis model this paper obtains the core factors builds an oil price system var model which uses demand supply price and inventory as endogenous variables and china s net imports as well as dollar index as exogenous variables then we set up a bvar tvp time varying parameter model to analyze dynamic impacts of core factors on oil price the results show that 1 oil prices became more sensitive to oil supply changes and the influence delays became shorter 2 the impact of oil inventories on oil prices with a time lag of two quarters but has a downward trend 3 the impact of oil consumption on oil prices with a time lag of two quarters and this effect is increasingly greater 4 the us dollar index is always the important factor of oil price and its control power increases gradually and the financial crisis occurred in 2008 further strengthens the influence of us dollar

the demand for gasoline abstract sufficient time must be allowed to elapse to assess fully the response of gasoline demand to price changes hitherto empirical work on the subject has generally not examined the period beyond 1975 moreover the extant time series studies concentrate almost exclusively on the usa this study extends both the observation period and the country coverage a vehicle stock adjustment model is estimated via its reduced form without explicit consideration of the vehicle stock itself however the estimation procedure incorporates the structure by way of constraints on the parameters cross section analysis offers additional evidence concerning the truly long run price elasticity the results suggest that there is no need to resort to elaborate models to explain adequately gasoline demand gasoline demand exhibits a long run price elasticity near unity with time lags exceeding six years while there is tentative evidence that the duration of these lags is not fixed

quantitative restrictions and the welfare effects of capital inflows abstract this paper explores the welfare effects of capital inflows when some imports are subject to quantitative restrictions it is shown that in a heckscher ohlin model where all imports are restricted by quotas and some fraction of the initial domestic capital stock is foreign owned a capital inflow is welfare improving regardless of the ranking of sectoral factor intensities with sector specific capital stocks and both tariff ridden and quota restricted imports the consequences of direct foreign investment in any sector are uncertain and depend upon whether the two imports are compensated substitutes or complements as well as the characteristics of production

mass car ownership in the emerging market giants the typical urban household in china owns a tv a refrigerator a washing machine and a computer but does not yet own a car in this paper we draw on data for a panel of countries and detailed household level surveys for the largest emerging markets to document a remarkably stable relationship between gdp per capita and car ownership highlighting the importance of within country income distribution factors we find that car ownership is low up to per capita incomes of about us 5000 and then takes off very rapidly several emerging markets including india and china the most populous countries in the world are currently at the stage of development when such takeoff is expected to take place we project that the number of cars will increase by 2 3 billion between 2005 and 2050 with an increase by 1 9 billion in emerging market and developing countries we outline a number of possible policy options to deal with the implications for the countries affected and the world as a whole marcos chamon paolo mauro and yohei okawa

export performance and export import linkage requirements this paper examines the resource allocation effects of two policies widely employed by developing countries to improve their trade balances compared to free trade both export performance and export import linkage policies may actually worsen the balance of trade unless they are coupled with an import barrier on final goods even with such barriers an export import linkage policy still may not cause the trade balance to improve the effects of both policies on a number of domestic variables are discussed profit and output of domestic exporters can increase under trade performance policies

financial market segmentation and choice of exchange rate regimes we study the choice of exchange rate regime in a small open economy with segmented asset markets subjected to financial sector shocks we show that the state contingent optimal policy facilitates risk sharing between asset market participants and non participants and is countercyclical our results establish that contrary to existing literature flexible exchange rates mimic optimal policy and welfare dominates fixed exchange rates

voluntary export restraints and foreign investment abstract this paper develops a model in which both voluntary export restraints vers and foreign investment can be considered we investigate the welfare effect of additional foreign investment under vers it is demonstrated that if the commodity subject to vers is more intensive in capital in the importing country which is assumed to be a debtor country additional foreign investment into that country raises its welfare

the emergence of rural transport strategies in response to rising fuel costs abstract rising and sometimes volatile fuel prices pose a challenge for rural organizations reliant on long distance transport to understand the coping mechanisms used by such organizations we survey rural business strategies in israel where fuel prices are high and urban development is concentrated in the country s geographic center the businesses surveyed are operated by kibbutzim historically collective communities that are now in various stages of privatization analysis of the transport strategies employed by nearly 100 organizations in three regions of varying remoteness and isolation shows that firms rely on distinct strategies such as localization and high value density localization was found to be prevalent in all regions as it requires little capital investment strategies exploiting high value density including information based services were prevalent in remote and isolated regions where sensitivity to transport costs is acute non remote firms were less inclined toward strategic adaptation preferring non disruptive changes such as cheaper shipping modes the development implications of these transport strategies are consistent with rural economic trends observed throughout the developed world if transport costs continue to rise rural firms may shrink the radius of their sales and labor pools or search for more lucrative products to reduce their relative transport costs

money interest rates and exchange rates with endogenously segmented markets we analyze the effects of money injections on interest rates and exchange rates when agents must pay a baumol tobin style fixed cost to exchange bonds and money asset markets are endogenously segmented because this fixed cost leads agents to trade bonds and money infrequently when the government injects money through an open market operation only those agents that are currently trading absorb these injections through their impact on these agents consumption these money injections affect real interest rates and real exchange rates the model generates the observed negative relation between expected inflation and real interest rates as well as persistent liquidity effects in interest rates and volatile and persistent exchange rates

is demand for polluting goods manageable an econometric study of car ownership and use in mexico abstract our motivation for estimating a demand system for gasoline and cars is its strategic relevance to policy objectives such as pollution control if demand is responsive to pricing demand reductions for polluting goods will provide an important share of the pollution reductions otherwise cleaner technologies will have to do most of the job we estimate a model of gasoline demand and car ownership in mexico using a panel of annual observations by state key features that we introduce include instrumental variables on differenced data and the treatment of possible dynamics measurement errors in the data and unobserved individual state characteristics we use tests of serial correlation in the a residuals to model the dynamics properly the resulting demand system is quite responsive to pricing even in the short term 0 6 for the own price elasticity of gasoline but we emphasize a medium to long term perspective of 5 10 years as most relevant for policy five to ten year elasticity estimates are in the range of 1 25 to 1 13 applying these elasticity estimates to data on pollution control options for the vehicle fleet in mexico city the costs of reaching a target for pollution reductions would be 45 more expensive if one were not willing to use a demand management instrument such a gasoline tax in the control program

an exploration in the theory of exchange rate regimes three exchange rate regimes a float a one sided peg and a cooperative peg are evaluated and compared in terms of efficiency and welfare levels the framework of analysis embodies country specific monies with the money of each country being used to transact in its commodity markets and its currency denominated bonds welfare levels depend only on consumption levels in the presence of perfect foresight all equilibrium allocations are pareto efficient in a floating exchange rate regime the perfect foresight equilibrium allocation coincides with an equilibrium of a costless barter economy the same result holds in a one sided peg if the pegging country s exchange rate stabilizing authority breaks even over time in a cooperative peg regime there is a different equilibrium allocation for each combination of exchange rate levels and monetary policies problems of policy coordination and conflicts in desired monetary policies are discussed

poverty inequality and welfare this paper argues that in order to produce a coherent account of pov erty that makes it more than just a facet of inequality it is essent ial to capture at the individual level those factors that a k sen p townsend and others have argued to be important in generating po verty it is shown that having done this it is possible to produce me asures of poverty and inequality that are clearly and systematically related to each other and to the overall level of welfare but in whi ch poverty emerges as more than just a facet of a wider and more gene ral concern with inequality copyright 1987 by royal economic society

effects of foreign investment in the presence of unemployment abstract in this paper we present a simple model of unemployment in the presence of foreign investment in the traded sector more foreign investment increases employment in the nontraded sector but may or may not increase employment in the traded sector the effect on total employment is also ambiguous in a two country framework with foreign investment itself a variable we show that foreign investment should most likely be subsidized rather than taxed moreover the employment maximizing tax on foreign investment is shown to be less than the optimum tax

trade policies and welfare in a harris todaro economy in many developing countries rising unemployment is often attributed to increases in foreign imports triggered by declining foreign prices of imports to correct the chronic unemployment problem some developing countries chose an import substitution strategy by shutting off imports whereas others adopted an outward oriented policy by promoting exports north american free trade agreement nafta was favored by mexico but opposed by organized labor in this country because it was feared that nafta may increase unemployment in the u s which of these policies is more effective in reducing unemployment and raising domestic income protection has been ardently supported as a practical cure for unemployment in chile and argentina and many other ldcs in latin america similarly india adopted import substitution strategies behind high protection and a considerable bias against exports 1 the literature has also justified the use of tariffs for small countries under uncertainty and unemployment 10 9 but in general protection distorts the trade pattern and magnify the extent of the leontief paradox by limiting imports of capital intensive products into these developing countries that suffer from high labor unemployment 7 in the literature there have been two types of models that analyze trade problems in the presence of unemployment the generalized unemployment models have been developed by brecher 5 6 and batra and seth 3 2 in these models wage rigidity is ubiquitous and unemployment exists in all sectors and they are appropriate to analyze the impact of trade policies on unemployment in developed economies the harris todaro ht hereafter model 13 on the other hand assumes sector specific wage rigidity and permits unemployment only in the urban sector thus the ht model is appropriate for investigating the impacts of trade policies of ldcs that suffer

endogenous market participation and the general equilibrium value of money we study the monetary theory implications of fixed costs associated with trade in private assets we show that with heterogeneous endowment profiles it is possible for an endogenous subset of agents to hold currency even when it is dominated in return by a competing asset with respect to positive issues in monetary theory the model implies that changes in the steady state growth rate of the money supply have a negative effect on real interest rates because of endogenous market participation measures on the normative side we show that there may be an equity efficiency trade off from monetary deflation

pattern of trade between underemployed economies in this paper the authors analyze the factors determining the pattern of trade between underemployed economies they find among other things that a low wage land abundant country exports the land using labor intensive product to a high wage capital abundant country the authors also find conditions under which a high wage capital rich country may export the labor intensive product the leonteif paradox copyright 1990 by the london school of economics and political science

passenger transport modal split based on budgets and implication for energy consumption approach and application in china transport will be the strongest growing energy demand sector in the future especially in developing countries like china and it needs more attention the evolution of transport structure is very important in the dynamic of transport development and therefore worth emphasis in this study a modal split model maximizing spatial welfare and constrained by travel money budget and time budget is developed this approach differs from the general econometric based approach used in most existing macro transport studies and deals with the cost and speed of transport modes as important variables explicitly the model is then applied to china s transport sector together with sensitivity test despite many data problems the decomposition of energy consumption generated from bottom up model based on this modal split identified the importance of modal split and turnover expansion in the next 30 years which should be a stronger area of focus in transportation studies

urban rural structural adjustment urban unemployment with traded and non traded goods abstract this paper extends the harris todaro model to include non traded goods and to analyze structural adjustment in ldcs we assume that the urban region produces two goods a manufactured good and an urban non traded good and the rural region also produces two commodities an agricultural and a rural non traded good our results reveal an asymmetry in the behaviour of the urban and rural regions in response to parametric changes or external shocks the effects of such changes on the endogenous urban variables are completely determinate however the responses of the endogenous variables in the rural region are ambiguous a deterioration in the terms of trade increases the relative price of the urban non traded good and increases its output at the expense of the urban traded good thus structural adjustment in urban and rural areas may be in opposite directions non regional models of structural adjustment ignore the possibility of having opposite effects in the urban and rural areas our results also provide a generalization of the dutch disease type phenomenon to a model with migration and unemployment

interest rates and inflation a consensus has emerged among practitioners that the instrument of monetary policy ought to be the short term interest rate that policy should be focused on the control of inflation and that inflation can be reduced by increasing short term interest rates at the center of this consensus is a rejection of the quantity theory such a rejection is a difficult step to take given the mass of evidence linking money growth inflation and interest rates increases in average rates of money growth are associated with equal increases in average inflation rates and interest rates these observations need not rule out a constructive role for the use of short term interest rates as a monetary instrument one possibility is that increasing short term rates in the face of increases in inflation is just an indirect way of reducing money growth sell bonds and take money out of the system another possibility is that while control of monetary aggregates is the key to low long run average inflation rates an interest rate policy can improve the short run behavior of interest rates and prices the shortrun connections among money growth inflation and interest rates are very unreliable so there is much room for improvement these possibilities are surely worth exploring but doing so requires new theory the analysis needed to reconcile interest rate policies with the evidence on which the quantity theory of money is grounded cannot be found in old textbook diagrams

does china factor matter an econometric analysis of international crude oil prices abstract whether china s crude oil imports are the culprit of oil price volatility these years has not been quantitatively confirmed therefore this paper empirically investigates the role of china s crude oil net imports in brent price changes from october 2005 to november 2013 based on an econometric analysis the results indicate that during the sample period china s crude oil imports do not significantly affect brent price changes no matter in the long run or short run therefore the blame for china s crude oil imports to cause the dramatic fluctuations of international oil price has no solid evidence also there exists significant uni directional causality running from the brent price to china s crude oil imports at the 5 level besides the response of the brent price to china s crude oil imports is found positive but slight and the brent price responds more significantly to us dollar exchange rate and oecd commercial inventory than to china s crude oil imports in the short run finally the contribution of china s crude oil imports to brent price movement is about 10 which is less than that of us dollar exchange rate but larger than that of indian crude oil imports or oecd commercial inventory

strategic oil stockpiling for energy security the case of china and india abstract compared with the developed countries the developing countries could be more vulnerable to oil supply disruptions due to their lack of strategic petroleum reserves sprs several developing countries including china and india are establishing their sprs to ensure energy security in the common world oil market one country s spr decisions can be affected by the decisions of other countries this paper investigates the spr policies of china and india two of the largest developing countries in a game theoretic framework where the interactions between the two countries are taken into account the results show that players equilibrium stockpiling strategies and total expected costs could vary significantly with the initial oil market state stockpile acquisition capacity and the probabilities for disruptions to persist

international factor mobility non traded goods tariffs and the terms of trade the present paper develops a general model with one imported one exported many non traded goods where some factors of production are internationally mobile within this framework the analysis establishes the validity of some earlier results and extends others that is 1 a tariff increase reduces the country s welfare 2 tariff induced international factor flows reduce a country s welfare 3 an improvement in a country s terms of trade in the presence of a tariff raises its welfare more when factors are internationally mobile than when not and 4 with preferential trading agreements trade creation always improves the country s welfare while trade diversion may or may not

energy policies for managing china s carbon emission abstract the well documented close relationship between economic growth and energy use indicates that the emergence of a country as an economic power cannot occur without increased in energy use but just as the scale of china s rise as an economic power has no clear parallel in history its conflict between economic growth and energy use has also shattered all precedents this planet s future energy scenario hinges on the ability of this decoupling the question this policy forum addressed is how to find the optimum way to accomplish this decoupling through government directive government centered command and control approaches or cac or market forces market based instruments or mbi it concludes that market rather than government can decide the optimum way to decouple china s economic growth from energy use facilitating this decoupling driven by market force requires getting the prices right for energy

gasoline prices gasoline consumption and new vehicle fuel economy evidence for a large sample of countries abstract countries differ considerably in terms of the price drivers pay for gasoline this paper uses data for 132 countries for the period 1995 2008 to investigate the implications of these differences for the consumption of gasoline for road transport to address the potential for simultaneity bias we use both a country s oil reserves and the international crude oil price as instruments for a country s average gasoline pump price we obtain estimates of the long run price elasticity of gasoline demand of between 0 2 and 0 5 using newly available data for a sub sample of 43 countries we also find that higher gasoline prices induce consumers to substitute to vehicles that are more fuel efficient with an estimated elasticity of 0 2 despite the small size of our elasticity estimates there is considerable scope for low price countries to achieve gasoline savings and vehicle fuel economy improvements via reducing gasoline subsidies and or increasing gasoline taxes

tariff protection and taxation of foreign capital the welfare implications for a small country abstract this paper extends recent studies by deriving sufficient conditions for tariff immiserization in a small country in the presence of internationally mobile sector specific capital the returns of which are taxed or subsidized necessary conditions for a welfare augmenting tariff are also discussed and the analysis is extended to the welfare implications of changes in the tax or subsidy rate on the earnings of migrating capital

variable returns to scale urban unemployment and welfare the proposition that free trade is superior to no trade has a classical ancestry adam smith and ricardo were amongst the first proponents of free trade samuelson 26 proved and it is held by economists today that free trade is the optimal policy in the presence of standard paretoconditions it is also generally agreed amongst economists that lower trade intervention is superior to higher trade intervention given competitive conditions in a small country these propositions do not hold however in the presence of factor market imperfections such as wage differentials in a small country and therefore production or wage subsidies improves social welfare the two models which are generally used to investigate the positive as well as normative aspects of trade theory in the presence of unemployment are the uniform real minimum wage model which is based on the assumption of general rigidity of real wage in one or two sectors of production and the sector specific minimum wage model which focuses on the phenomenon of rural urban migration in the face of large scale urban unemployment these two models are commonly utilized by trade theorists to analyze trade and unemployment specifically studies by haberler 13 johnson 16 batra and seth 3 findlay 12 and brecher 6 7 investigate the consequences of rigid factor prices for a small country whereas the normative as well as positive aspects of sector specific unemployment have been explored by harris and todaro 15 bhagwati and srinivasan 4 5 and more recently by batra and naqvi 2 das 10 and kahn 19 it has been correctly observed that the introduction of an exogenously specified real minimum wage among other things generates unorthodox results concerning unemployment and gains from trade a large body of research has also been concerned with the welfare implications of different commercial policies in the context of variable returns to scale kemp and negishi 20 have pointed out the beneficial effects of trade in the presence of variable returns to scale production subsidy and consumption taxes eaton and panagariya 11 have analyzed the question of gains from trade in the presence of variable returns to scale and in the context of pareto welfare criterion whereas choi and yu 8 have examined the welfare implications of tariffs and consumption taxes as well as the welfare rankings of these policies under variable returns to scale while panagariya and succar 25 have modified the necessary and sufficient conditions for stability under increasing returns to scale in urban sector

financial frictions and the choice of exchange rate regimes i introduction this article provides a quantitative assessment of the role of financial frictions for the choice of exchange rate regimes in a two country model the standard new open economy model neglects the role that financial frictions can play for the international transmission of shocks and for the optimal choice of exchange rate regimes however several historical episodes such as the global financial crises during the gold standard regime or the exchange rate crisis during the european monetary system ems have shown the dangers of a close association between financial instability and pegged exchange rates in general pegged exchange rates tend to reduce monetary policy flexibility and those constraints become even more stringent when the domestic economy faces credit frictions nowadays those issues have acquired policy relevance for the euro area as some accession countries entered a system of managed exchange rates with the euro zone known as the erm ii central bank agreement 1 the relinquishing of part of their monetary policy flexibility might be a concern as some of those countries are still characterized by unstable financial markets to analyze the above mentioned issues i use an artificial two country economy characterized by imperfect financial integration in the market for international securities and sticky prices in an imperfectly competitive framework the introduction of sticky prices is particularly helpful for comparing different monetary arrangements to this economy otherwise similar to those analyzed in some of the recent open economy macro literature 2 i add borrowing constraints on investment associated with balance sheet effects in both countries 3 doing so adds realism to the model and moves a step forward toward integrating the analysis of the domestic and the international transmission mechanisms i simulate the calibrated economy under monetary and productivity shocks and i compare three different exchange rate regimes that is hard pegs managed exchange rates and floating exchange rates to evaluate the relative performance of the different regimes i rely on the comparison of volatilities for the main macro variables and on a simple welfare metric i first consider shocks originated in the foreign country in the absence of financial frictions floating exchange rates deliver good stability properties under both productivity and monetary policy shocks this result confirms milton friedman s 1953 case for flexible exchange rate he argued that in presence of sticky prices floating exchange rates deliver better insulation properties from foreign shocks as they allow relative prices to adjust faster in presence of financial frictions such insulating property is strengthened further the intuition runs as follows under fixed or managed exchange rates an external shock with devaluation pressures forces the monetary authority to raise interest rates with a consequent increase in the cost of loans the presence of borrowing constraints on investment exacerbates the tightening effect to highlight the impact of borrowing constraints on investment i compare the dynamic properties of the economy with and without agency costs both the absolute value for the volatilities of the main macro variables output investment inflation consumption asset prices and return on capital and the difference in the same volatilities between the two regimes are higher when credit frictions are introduced into the model fixed and managed exchange rate regimes also appear to steepen the typical trade off between inflation and output volatility this effect is shown by illustrating the fact that the sacrifice ratio the output inflation volatility ratio raises when moving from floating to fixed exchange rate regimes and that such an increase is higher in presence of credit frictions i therefore test the robustness of the results by analyzing the model with financial frictions under domestic shocks and under symmetric and correlated shocks

export share requirements and unemployment the case of quota trade restrictions such as import tariffs have been a common practice for protecting domestic import competing industries in most less developed countries ldcs foreign firms may however circumvent such protection through direct investment in the host countries this is the well known tariff jumping direct foreign investment which has been examined by brecher and diaz alejandro 7 they show that the foreign capital inflow leads to overproduction of the output of tariff protected sectors and hence results in welfare reduction recently rodrik 17 demonstrates that export share requirements when applied to the output produced by foreign capital may offset the negative effect of foreign direct investment through the contraction of tariffprotected overproduced sectors thus an increase in such a requirement may actually improve welfare this result contradicts the earlier finding of davidson matusz and kreinin 11 which is obtained from a partial equilibrium framework the existing literature on export share requirements remains deficient in two respects first the full employment models have been deployed ignoring the fact that most ldcs suffer from massive unemployment second the analysis has been confined by and large to tariff protection thereby neglecting quantitative trade restrictions e g import quotas it is noteworthy that it is quotas rather than tariffs which constitute a major constraint on imports by developing countries 2 the purpose of this paper is thus to remedy these two shortcomings by developing a sectorspecific unemployment general equilibrium model with quota restrictions on imports as noted by richardson 16 export performance requirements operate in a second best environment import

factor mobility and customs unions theory the standard theory of customs unions originated with the pathbreaking work of viner 11 viner draws a distinction between the trade creating and the trade diverting effects of customs unions trade creation involves a shift of consumption of the importable good from a high cost domestic producer to a lower cost foreign producer trade diversion however involves a switch from the lowest cost external producers to a higher cost producer viner argues that trade creation improves the home country s welfare and trade diversion dampens it viner s analysis was refined by gehrels 4 lipsey 8 and batra 1 the theory was reexamined in light of unemployment by yu 12 and in the presence of variable returns to scale by choi and yu 3 viner s main results were modified accordingly underlying the standard theory of customs unions is the assumption that factors are perfectly mobile between industries in a given country this assumption simplifies the analysis but cannot be supported by empirical observations it is notable that the two sector trade model has been recently extended to accommodate varying degrees of factor mobility mussa 10 considered the case in which capital is sector specific but labor displays any degree of mobility grossman 5 posited capital immobility but allowed perfect labor mobility casas 2 studied the implications of labor immobility which gives rise to an endogenous wage differential hill and mendez 6 developed a general model which allows any degree of mobility in both factors yu and parai 14 adopted casas approach to examine the gains from trade issues this factor mobility literature has generated many interesting results in the neoclassical trade theory the implications of factor immobility for the customs union theory however remain by and large unexplored the purpose of this paper is to make a modest contribution by considering the customs unions theory in the presence of any degree of mobility of both factors as a secondary contribution we elucidate how the presence of factor immobility makes the extent of factor price differentials

money and exchange rates in the grossman weiss rotemberg model abstract we analyze the impact of monetary policy on inflation interest rates and exchange rates in a model with segmented asset markets developed by grossman and weiss 1983 and rotemberg 1984 1985 we find parameters for which real and nominal exchange rates in this model are 1 much more volatile than interest rates inflation rates and money growth rates 2 highly correlated with each other and 3 highly persistent while this model fails to match the data in other important respects it illustrates a potentially useful approach to modelling exchange rate behavior

urban unemployment terms of trade and welfare it is generally accepted prior to 1970 that a deterioration in the terms of trade results in lower social welfare in particular prebisch 11 and singer 12 have expressed the basic concern with the terms of trade the secular deterioration in the terms of trade facing less developed countries ldcs leads to income and welfare losses batra and pattanaik 2 nevertheless shows that a deterioration in the terms of trade in the presence of an intersectoral wage differential may raise welfare bhagwati and brecher 5 demonstrate that a decline in the terms of trade can improve real income if capital is mobile internationally recently anam 1 obtains a similarly interesting result for an economy engaging in quota induced rent seeking activities it is notable that none of these studies considers a key feature inherent in a typical ldc namely the existence of substantial urban unemployment thus the purpose of this paper is to examine the welfare impacts of terms of trade losses for ldcs plagued by pervasive urban unemployment the well known harris todaro 7 framework of sector specific unemployment is utilized in addition we derive and contrast various welfare effects of a change in the terms of trade when a ldc pursues alternative import substitution policies i e tariffs vs quotas over the short vs the long run the paper is organized as follows section ii develops the model and provides the transformation relation between urban and rural outputs section iii examines the welfare effects of an exogenous shift in the terms of trade for a tariff or quota distorted economy in the short run as well as in the long run finally concluding remarks are set out in section iv

determinants of china s energy imports an empirical analysis sustained economic growth in china has triggered a surge of energy imports especially oil imports this paper investigates the determinants of china s energy import demand by using cointegraiton and vecm techniques the findings suggest that in the long run growth of industrial production and expansion of transport sectors affect china s oil imports while domestic energy output has a substitution effect thus as the chinese economy industrializes and the automotive sector expands china s oil imports are likely to increase though china s domestic oil production has a substitution effect on imports its growth is limited due to scarce domestic reserve and high exploration costs it is anticipated that china will be more dependent on overseas oil supply regardless of the world oil price

long run gasoline demand for passenger cars the role of income distribution it is commonly agreed that the level of income and prices are crucial determinants of the consumption of motor gasoline the respective long run price and income elasticities are regularly calculated using cross sectional models despite the acknowledgement of the role of income distribution it plays no role in intercountry cross sectional models this is due to a lack of appropriate data this paper shows that the omission of distributional characteristics provides misleading elasticities using available distributional measures this paper is referring to an income threshold which is crucial to the acquisition of an automobile it is shown that on the one hand in poor countries an unequal income distribution is needed to enable at least some people to buy automobiles on the other hand in wealthy countries an unequal income distribution would exclude some people from acquiring automobiles hence depending on the income level inequality has a diverging impact on the ability to buy durable goods the second part of this paper develops a pooled 90 country model to examine this approach empirically it could be shown that distribution variables are highly significant to explain the demand for automobiles and motor gasoline moreover the consideration of the distribution of income leads to a considerable decrease in income elasticity values this is mainly due to the positive correlation between income level and income equality within the sample

financial openness financial frictions and optimal monetary policy increasing financial integration challenges the optimality of inward looking strategies for optimal monetary policy those issues are analyzed in an open economy where foreign net lending and the current account are determined by a collateral constraint durables represent collateral the current account features persistent imbalances but can deliver a long run stationary equilibrium the comparison between floating and managed exchange rate regimes shows that the impossible trinity is reversed higher financial integration increases the persistence and volatility of the current account and calls for exchange rate stabilization in this context the ramsey plan too prescribes stabilization of the exchange rate alongside with domestic inflation

multinational firms and the theory of international trade and investment tinational corporation in the arena of economic activity and political influence trade theorists have either ignored it or expressed unguarded skepticism at the ability of the conventional trade models to successfully capture and analyze the features of this new phenomenon the purpose of this paper is twofold first by building upon the contribution by richard caves we will show that the traditional trade models can be adapted in a way that preserves most if not all of the attributes introduced by international firms 2 second we will conduct a comparative statics analysis to explore the implications of tariffs and taxes for resource allocation and international capital movements our results here confirm what has already been well established in myriad empirical studies that maturation of the international firm has vastly increased economic interdependence among trading countries and that few nations can eschew the ripples caused by economic policies of other nations 3

extensive margins and the demand for money at low interest rates we argue that the relevant monetary decision for the majority of u s households is not the fraction of assets to be held in interest bearing form but whether to hold any such assets at all we call this the decision to adopt the financial technology we show that the key variable governing the adoption decision is the product of the interest rate times the total amount of assets this implies that the interest elasticity of household money demand at low interest rates can be estimated from the variation in asset holdings in a cross section of households rather than historical interest rate variations we do so with the 1989 survey of consumer finances we find that a the elasticity of money demand is very small when the interest rate is small b the probability that a household holds any amount of interest bearing assets is positively related to the level of financial assets and c the cost of adopting financial technologies is negatively related to participation in a pension program at intere

imperfect labor mobility and unemployment in ldcs in the two sector two factor general equilibrium literature generic unemployment has been introduced under the assumption of decreasing returns to scale in production see e g batra and seth 1 295 306 and yu 10 399 404 whereas sector specific unemployment has been introduced under the assumption of sticky wages e g harris and todaro 6 136 42 corden and findlay 5 59 78 khan 8 527 47 and marjit 9 527 47 in either case however labor is assumed to be perfectly mobile between two sectors the latter assumption has recently been a major topic of further research in the two sector general equilibrium literature specifically it is argued that in a perfectly competitive environment despite significant intersectoral wage differential caused by various parametric policy changes enough labor do not move from the low wage to the high wage sector to equate the wage rates in two sectors even in the long run locational preferences attachment to existing arrangements and also the high costs of relocation are usually cited as the possible reasons behind the sluggish movement of labor from one sector to the other casas 2 747 61 in a pioneering article has modeled this phenomenon of general immobility of labor in a standard two sector model of production in his model however casas assumes full employment of labor the purpose of the present paper is to extend the casas model further by incorporating unemployment caused by sector specific sticky wages of the harris todaro variety and examine the effects of growth and trade policies on output employment and welfare of a small country we will highlight the role of the elasticity of labor mobility parameter in our main results and demonstrate that there exists a critical minimum value of the elasticity of labor mobility parameter that will ensure the validity of the conventional results even in the world of imperfect labor mobility several interesting results emerge from our analysis in particular we have shown that capital accumulation causes urban unemployment to rise and the optimal tariff for a small open economy is positive the paper is organized as follows in section ii we lay out the basic model of labor immobility and unemployment and in section iii we derive the basic comparative static results in

do emerging markets matter in the world oil pricing system evidence of imported crude by china and india abstract this paper provides empirical evidence on the changing structure of world oil price system by identifying an additional driver emerging market factor we choose china and india as a representative of emerging markets to examine if the quantity of crude oil imported by china and india is significant in the existing oil pricing system kaufmann et al 2004 our data starts from january 2002 and ends in march 2010 which includes the oil shock of 2007 2008 we utilize cointegration and error correction model framework developed by engle granger 1987 and gregory hansen 1996 in the analysis our results indicate that demand from emerging markets has become a significant factor in the world oil pricing system since 2003 this result is significant as it lends empirical support to the widely held conjecture that the oil shock of 2007 2008 is a demand led shock hamilton 2009 our result also has significant policy implications that go beyond the oil shock the emerging market factor is there to stay and reflects the changing power between emerging and developed economies in the world economic system as a result of decades of fast economic development in the former it will certainly influence policy issues related to oil and beyond

welfare approaches to the measurement of poverty a set of poverty indices is constructed which is based on an explicit view of the loss of social welfare which results from the existence of poverty in comparison t o a society in which poverty has been eliminated the indices are based on the entire distribution of income rather than only the incomes of the poor and thus embody the concept of relative deprivation formal properties of the indices are developed together with their relationship to welfare based inequality indices both are seen as subsets of a wider choice of measures dependent on a particular choice of reference distribution copyright 1987 by royal economic society

china on the move oil price explosion abstract rapid expansion of highway and jet traffic in china has created a surge of demand for oil products putting pressure on world energy markets and petroleum product prices this paper examines trends in freight and passenger traffic to assess how growth in china s transport demand relates to growth in china s economy as well as the energy intensity of transport based on assumptions about demand elasticity and energy intensity a range of scenarios is developed for china s oil demand through 2020 incremental oil demand from china s transport sector is then compared with world oil demand projections to assess the likely impact on world oil prices the finding is that new demand from china s transport sector would likely raise world oil prices in 2020 by 1 3 in reference scenarios or by 3 10 if oil supply investment is constrained

unemployment and foreign capital the relative opportunity costs of domestic labour and welfare the consequences of increased foreign capital for an economy with unemployment are analyzed under different assumptions that influence the relative oportunity costs of domestic labor the investigation suggests that the implications of the literature on the welfare effect of increased foreign capital are misleading the paper shows that welfare gains result from increased foreign capital if the opportunity costs of labor are sufficiently low relative to the wages earned by laborers employed by new foreign capital a number of cases where this occurs are presented the findings of the paper suggest that cases where increased foreign capital must be welfare harming represent extreme parameterizations in the set of possibilities copyright 1991 by the london school of economics and political science

examining the leontief paradox in u s agricultural trade abstract factor intensity of united states agricultural trade is examined in the context of leontief s classic paradox using leontief s method as well as methods developed recently by leamer and others findings indicate that factor endowments are important determinants of u s agriculture s comparative advantage in trade as suggested by the heckscher ohlin theory

evaluating the role of subsidy reform in addressing poverty levels in malaysia a cge poverty framework abstractmalaysia as one of the top subsidised countries around the world has launched to reduce subsidies to capture its development goals this study therefore analyses the effects of the subsidy reform on the macroeconomic welfare and poverty levels of malaysia by applying a cge model the findings suggest that subsidy removal leads to significant falls in both income and consumption of rural urban and non citizen households and consequently decreases their welfare however poverty levels among rural households will most likely increase significantly when compared to urban households due to their relatively low level of income compared to other groups

the effects of foreign investment in the presence of a factor market monopsony abstract this paper introduces a foreign monopsony within the ricardo viner production model to show that the observed behavior of host country interest groups labor s opposition and domestic capital s support towards greater foreign investment need not be inconsistent with the proposition that an inflow of foreign capital raises real wages and lowers the return to domestic capital it is shown that an increase in foreign investment intensifies the degree of monopsonistic exploitation of labor and produces greater supranormal profits for the foreign monopsony moreover if these profits are distributed to domestic capitalists according to some fixed proportion this increase in income may offset the decline in their real return

gasoline demand and car choice estimating gasoline demand using household information in recent years calls for carbon taxes as a policy tool to combat global warming have kept a discussion of the price and income elasticities of gasoline demand alive to date gasoline demand elasticity estimates are almost exclusively based on aggregate data that are subject to aggregation problems and make distributional concerns impossible to address by using household level data from the panel study of income dynamics psid and imputed fuel efficiency measures and gasoline prices i estimate household demand for gasoline and the corresponding price and income demand elasticities an attempt is made to include data on the car stock in the estimation since car portfolio and gasoline demand decisions are closely related empirical results from a selection corrected gasoline demand regression suggest low short run price and income elasticities and clear differences in gasoline demand across the population these results suggest that a gasoline tax is not likely to result in large decreases in gasoline consumption while potentially imposing hardship on identifiable segments of the population

impacts of energy subsidy reform on the malaysian economy and transportation sector malaysia is paying a high level of subsidies on the consumption of energy about 5 of its gdp therefore reforming the energy subsidies as planned by the government will have a significant impact on household welfare and energy intensive sectors such as the transport sector this study employs a computable general equilibrium cge model to highlight the transmission channels through which the removal of energy subsidies affects the domestic economy the findings show that the shock increases real gdp and real investment while decreasing malaysian total exports and imports the removal of energy subsidies also decreases the aggregate energy demand and consequently decreases the level of carbon emissions in the malaysian economy in addition households experience significant falls in their consumption and welfare the transport sector is significantly influenced through an increase in production costs due to an increase in the prices of intermediate inputs the total output and total exports of the whole transport sector decrease while its imports increase in addition the use of all kinds of transport by households decreases significantly the malaysian energy subsidy reform leads to an initial decrease in co2 emissions and demand for electricity gas and petroleum products in the entire transport sector

gasoline demand in the oecd an application of pooling and testing procedures abstract this study utilizes a pooled inter country data set finding the long run price elasticity falls in the range 0 55 to 0 9 depending on the choice of pooled estimators the estimators included the ols within and between country estimators plus five feasible gls estimators even allowing for a ten year distributed lag on price to reflect changes in auto efficiency characteristics the within country estimator yields appreciably more inelastic estimates than did the o s estimator which was heavily influenced by the between or inter country variation this difference raises intriguing questions for future research

customs union and unemployment in ldcs abstract welfare effects of customs union are examined for a small open economy with unemployment of labor of harris todaro type and some new results are reported specifically it is demonstrated that for ldcs afflicted with urban unemployment trade creating customs union continues to be an effective policy

segmented asset markets and optimal exchange rate regimes abstract this paper revisits the issue of the optimal exchange rate regime in a flexible price environment the key innovation is that we analyze this question in the context of environments where only a fraction of agents participate in asset market transactions i e asset markets are segmented under this friction alternative exchange rate regimes have different implications for real allocations in the economy in the context of this environment we show that flexible exchange rates are optimal under monetary shocks and fixed exchange rates are optimal under real shocks

analysis of perfonnance standards for direct foreign investments within the framework of a duopolistic model we investigate the impact of foreign investment standards on welfare output and employment minimum local content and export requirements reduce world output world welfare and the source country s welfare under certain conditions the decline in host country s consumer surplus resulting from diminished competition outweighs the shift of monopoly rent from the source country s firm to the host country s firm minimum content standards can increase host country s employment but only to a point marginal increases in the content requirement can actually reduce employment as the magnitude of foreign investment declines

optimal administered pricing under capacity constraints abstract this paper addresses the question of how pricing policies can improve the utilization of existing production capacities an optimizing input output model for the indian economy is developed for this purpose where the government s objective is to maximize growth subject to capacity constraints it is found that the optimal prices are related to the keynesian income multipliers associated with increases in the consumption of goods

lifetime incidence and the distributional burden of excise taxes this implies that low income households in one year have some chance of being higher income households in other years and significantly affects the estimated distributional burden of excise taxes this paper shows that household expenditures on gasoline alcohol and tobacco as a share of total consumption a proxy for lifetime income are much more equally distributed than expenditures as a share of annual income from a longer horizon perspective excise taxes on these goods are therefore much less regressive than standard analyses suggest this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item

oil development in china current status and future trends the future of oil has become an important topic of the discussion of energy policy in china this paper attempts to present a full picture of the current status and future trends of china s oil development through system analysis first we map a sankey diagram of china s oil flow to reveal the physical pattern of china s oil supply and consumption then we present the historical and ongoing trends of china s oil flow from key aspects such as oil demand oil resource availability technology improvement and policy adjustment based on these understandings we design three scenarios of china s oil demand in 2030 and analyze policy implications for oil saving automotive energy development and energy security from the analysis we draw some conclusions for policy decisions such as to control the total oil consumption to avoid energy security risks to enhance oil saving in all sectors with road transportation as the emphasis and to increase the investment on oil production and refining to secure oil supply and reduce emissions

tariffs quotas and voluntary export restraints with and without internationally mobile capital this paper presents a general framework for comparing the effects of tariffs quotas and vers voluntary export restraints both with and without international capital mobility expressions for the shadow price of foreign exchange and the shadow price of capital under each type of trade restriction are derived and it is shown that although international capital mobility raises the welfare cost of tariff protection it lowers the welfare cost of quantitative restrictions in most cases the effects of exogenous shocks in the presence of quotas are intermediate between those in the presence of tariffs and those in the presence of vers tarifs douaniers contingentements et restrictions volontaires d l exportation quand le capital est ou n est pas mobile internationalement l auteur presente un cadre general d analyse qu il utilise pour comparer les effets de tarifs douaniers de contingentements et de restrictions volontaires a l exportation dans des contextes ofu le capital est ou n est pas mobile internationalement l auteur derive le prix fictif du change etranger et le prix fictif du capital sous l un et l autre types de restrictions au commerce et montre que meme si la mobilite internationale du capital augmente le cofut en terme de bien etre de la protection tarifaire elle reduit le cofut en terme de bien etre des restrictions sur les quantites echangees dans tous les cas les effets de chocs exogenes quand des contingentements existent sont toujours dans la fourchette entre ceux qu on observe quand des tarifs douaniers existent et ceux qui prevalent quand des restrictions volontaires i l exportation existent

shocks effects of macroeconomic variables on natural gas consumption in nigeria structural var with sign restrictions abstract this paper has examined the transmission of shocks from macroeconomic variables namely money supply inflation exchange rate and real gdp onto natural gas consumption using structural var svar model with sign restrictions the results revealed that both in the short run and long run natural gas consumption responds significantly to the shocks emanating from money supply and real gdp while its response to inflation shock is significant only in the short run but exchange rate shock is not significant however money supply has contributed greater proportion of the shocks followed by the real gdp inflation and exchange rate in the ordering of the variance decomposition the paper recommends that nigerian authorities adjust the monetary policy tools towards regulating the money supply and checking the inflation rate to ensure increased demand for natural gas and sustained economic growth on the response of natural gas consumption to the shock in the exchange rate since the shock is positive though insignificant it implies that depreciation of the exchange rate can discourage the demand for foreign exchange imports and boost the local production which would reciprocally lead to more natural gas consumption and improved growth in the country

measuring welfare poverty and inequality a class of poverty measures is identified the members of which satisfy strong monotonicity and transfer conditions these measures are closely related to indices of income inequality based on the notion of a mean equivalent income a restriction on the class of admissible measures allows poverty to be interpreted in terms of the loss in mean equivalent income resulting from the fact that some people are poor copyright 1987 by royal economic society

capacity constraints alternative technologies and input output analysis abstract this paper extends the standard input output 10 model by introducing alternative technologies and capacity constraints a necessary and sufficient condition for the existence of solutions and two alternative sufficient conditions for the uniqueness of a solution have been developed

utility subsidy reform in abu dhabi a review and a computable general equilibrium analysis abstract electricity and water consumption in abu dhabi has increased substantially in recent years along with rapid economic and population growth as one of the oil producing economies located in arid regions abu dhabi s electricity and water are produced predominantly with fossil fuel based power water co generation which generate carbon emissions the consumption of electricity and water is heavily subsidized to support industrial growth lower cost of living and distribute state wealth to the population the low utility prices however may have contributed to high per capita carbon emissions for the emirate this paper reviews critical literature on energy subsidy policy for oil exporting economies we then examine the economic and environmental effects of water and electricity subsidy reduction in abu dhabi using a computable general equilibrium analysis the result shows that utility subsidy reduction alone increases gross domestic product gdp of the emirate through expanding the high value added service sector and reduces carbon emissions with decreasing carbon intensive industrial and utility productions meanwhile private consumption declines with decreasing wage electricity subsidy reduction in general has greater economic and environmental effects than water subsidy reduction the positive economic and environmental gains may incentivize utility subsidy reform in the long run when the negative wage effect is mitigated

country size currency unions and international asset returns differences in real interest rates across developed economies are puzzlingly large and persistent i propose a simple explanation bonds issued in the currencies of larger economies are expensive because they insure against shocks that affect a larger fraction of the world economy i show that indeed differences in the size of economies explain a large fraction of the cross sectional variation in currency returns the data also support additional implications of the model the introduction of a currency union lowers interest rates in participating countries and stocks in the nontraded sector of larger economies pay lower expected returns

empirical studies of depreciation this paper surveys empirical research on depreciation based on an econometric model of asset prices introduced by hall in 1971 and shows how hall s model provides a vehicle for unifying research on constant quality price indices and depreciation an additional objective of the paper is to illustrate the use of this research in constructing an integrated system of income product and wealth accounts a system of vintage accounts like that originated by christensen and jorgenson in 1973 is the key to successful integration
