natural resources curse or blessing are natural resources a curse or a blessing the empirical evidence suggests that either outcome is possible this paper surveys a variety of hypotheses and supporting evidence for why some countries benefit and others lose from the presence of natural resources these include that a resource bonanza induces appreciation of the real exchange rate deindustrialization and bad growth prospects and that these adverse effects are more severe in volatile countries with bad institutions and lack of rule of law corruption presidential democracies and underdeveloped financial systems another hypothesis is that a resource boom reinforces rent grabbing and civil conflict especially if institutions are bad induces corruption especially in nondemocratic countries and keeps in place bad policies finally resource rich developing economies seem unable to successfully convert their depleting exhaustible resources into other productive assets the survey also offers some welfare based fiscal rules for harnessing resource windfalls in developed and developing economies

balanced and unbalanced growth abstract a model is developed that shows how two sectors or regions interact out of steady state through product labor and capital markets and how if the former interaction dominates the growth of one sector pulls along the growth of the other while if the latter interactions dominate one sector or region booms while the other declines it is then shown why liberalization of foreign trade should lead to a transition from a lower to a higher steady state growth rate and why during the course of this transition growth might initially be even slower than before liberalization

consequences of lower oil prices and stranded assets for russia s sustainable fiscal stance abstract despite substantial oil and gas revenue russia s fiscal stance is unsustainable under our benchmark assumptions the permanent income rule requires a permanent tightening of the fiscal stance by 4 6 points of gdp delaying it by a decade implies that the fiscal stance needs to be tightened by a further 0 9 point this benchmark optimal policy ensures that depletion of oil and gas wealth is matched by an equal increase in above ground financial wealth its merits are highlighted by comparing it with the tougher alternative of the bird in hand rule and with projecting the current fiscal stance if oil and gas revenue rises by a half due to higher prices or more discoveries the fiscal stance needs to be tightened by only 3 2 points of gdp however if a large chunk of oil and gas has to be kept in the soil to meet international agreements to keep global warming below 2 c the permanent transfer drops to 2 0 of gdp and the fiscal stance needs to be tightened by 5 5 points of gdp

macro hedging for commodity exporters abstract this paper uses a dynamic optimization model to quantify the potential welfare gains of hedging against commodity price risk for commodity exporting countries we show that hedging enhances domestic welfare through two channels first by reducing export income volatility and second by reducing the country s need to hold precautionary reserves and improving the country s ability to borrow against future export income under plausible calibrations of the model the second channel may lead to much larger welfare gains amounting to several percentage points of annual consumption

stock market returns and inflation evidence from other countries this paper investigates the relation between common stock returns and inflation in twenty six countries for the postwar period our results do not support the fisher hypothesis which states that real rates of return on common stocks and expected inflation rates are independent and that nominal stock returns vary in one to one correspondence with expected inflation there is a consistent lack of positive relation between stock returns and inflation in most of the countries

interest rates and currency prices in a two country world abstract this paper is a theoretical study of the determination of prices interest rates and currency exchange rates set in an infinitely lived two country world which is subject both to stochastic endowment shocks and to monetary instability formulas are obtained for pricing all equity claims nominally denominated bonds and currencies and these formulas are related to earlier closely related results in the theories of money finance international trade

absorbing a windfall of foreign exchange dutch disease dynamics abstract the permanent income rule is seldom the optimal response to a windfall of foreign exchange such as that from a resource discovery absorptive capacity constraints require domestic investment and investment in structures requires non traded inputs the supply of which is constrained by the initial capital stock this particularly when combined with intra sectoral capital immobility delays adjustment and creates short run dutch disease symptoms as the real exchange rate sharply appreciates and overshoots its long run value optimal revenue management requires investing in the domestic non traded goods sector and a slow build up of consumption accumulation of foreign assets adjusts to accommodate the time paths of domestic consumption and investment

tax advice to developing countries an historical survey abstract the tax policy advice given to developing countries by foreign experts has been influenced by changing public finance doctrines development theory and policy and practices and debates in industrial countries current tendencies include less emphasis than formerly on taxation to mobilize savings in accordance with a national plan to reduce inequality and to influence resource allocation by special incentives governments are advised to avoid interfering with market directed allocations of resources high and progressive income tax rates high import duties and export taxes a value added tax is recommended for middle income countries

the value of fiscal discipline for oil exporting countries abstract the value of fiscal discipline is assessed by analyzing the role of fiscal policy as a transmission mechanism of oil price shocks in oil exporting small open economies fiscal policy is an important propagation channel taking policy as given by the data the model can successfully explain the responses of key macroeconomic variables but it is unable to explain these responses under counterfactual fiscal frameworks interestingly fiscal policy also seems capable of regulating the size of pass through furthermore fiscal policies that insulate the economy from oil price shocks seem to be welfare improving over procyclical ones

investment scaling up and the role of government abstractthis article studies the fiscal and welfare implications of a scaling up of public investment when the government is subject to inefficiencies on the spending and on the tax collection side in our simulations the scaling up of public investments results in higher long run output and consumption levels but requires a fiscal stabilization package in order to preserve fiscal sustainability the effects on consumers welfare after the fiscal adjustment are nontrivial our welfare analysis shows that consumers welfare is increased when the government smooths the fiscal adjustment via higher borrowing and not through an increase in taxation moreover the comparison between several stabilization packages via tax adjustment shows that higher welfare is achieved when the government relies mostly on taxation of capital as this allows higher levels of consumption lower fiscal costs that do not undermine fiscal sustainability can however be achieved if the government manages to reduce inefficiency in tax

sharing a ride on the commodities roller coaster common factors in business cycles of emerging economies fluctuations in commodity prices are an important driver of business cycles in small emerging market economies emes this paper documents how these fluctuations correlate strongly with the business cycle in emes a commodity sector is then embedded into a multi country emes business cycle model where exogenous fluctuations in commodity prices follow a common dynamic factor structure and coexist with other driving forces the estimated model assigns to commodity shocks 42 percent of the variance in income of which a considerable part is linked to the common factor a further amplification mechanism is a spillover effect from commodity prices to risk premia

time varying risk premia volatility and technical trading rule profits evidence from foreign currency futures markets abstract this paper re examines the efficiency of foreign currency futures markets by evaluating the role of time varying risk premia and volatility in explaining technical trading rule profits the results show that large parts of the technical rule profits can be explained by the time varying risk premia estimated from a general model for the conditional capm the bootstrap distributions for the profits under the null model average one third to one half of the actual profits and enclose the actual profits well within the 90 confidence intervals time varying conditional volatility explains an additional 10 of the profits

optimal dutch disease growth models of the dutch disease such as those of krugman 1987 matsuyama 1992 sachs and warner 1995 and gylfason et al 1999 explain why resource abundance may reduce growth however the literature also raises a new question if the use of resource wealth hurts productivity growth how should such wealth be optimally managed this question forms the topic of the present paper in which we extend the growth literature on the dutch disease from a positive to a normative setting we show that the assumptions in the previous literature imply that the optimal share of national wealth consumed in each period needs to be adjusted down however some dutch disease is always optimal thus lower growth in resource abundant countries may not be a problem in itself but may be part of an optimal growth path the optimal spending path of the resource wealth may be increasing or decreasing over time and we discuss why this is the case

mean variance theory in complete markets two paradigms in the pricing of risky assets are the complete markets model of arrow and debreu and mean variance pricing as embodied in the capital asset pricing model capm the former is primarily of theoretical interest in fact prior to the recent work of banz and miller 1978 and breeden and litzenberger 1978 there was little thought or hope of practical applications on the other hand the hegemony of the capm is due mostly to its apparent ease of applicability and to a lesser extent its empirical justification in a competitive market with no taxes transactions costs or institutional constraints on portfolio holdings the allocation of the available assets will be pareto optimal the end of period distribution of wealth or the consumption goods however will typically be pareto optimal only when there is available an arrow debreu security for each contingency since by definition a pareto superior reallocation is weakly preferred by all investors a complete set of arrow debreu markets should naturally arise provided they are not too costly to establish the complete markets model of arrow and debreu and the meanvariance capital asset pricing model capm are two paradigms of risky asset markets this paper provides an integration of these two theories we prove that the standard meanvariance separation theorem obtains in a complete market only if all investors have quadratic utility in addition the familiar capm pricing relation can hold for all assets in a complete market only if arbitrage opportunities exist on the positive side we show that the validity of this relation for the primary assets in a complete market is unaffected by the distribution of returns on the created financial assets

money bonds and foreign exchange in the theory of finance capital markets provide securities which allow the ownership of productive assets to be allocated among investors according to their willingness to bear risk in exchange for return and independently of their tastes for the productive services provided by the assets this paper uses the theory of finance to study the role of money as a productive asset and the transformation of money into a portfolio asset true to its purpose the capital market provides securities nominal bonds that allow an allocation of the current services of the money supply according to its current productivity and without regard for its future purchasing power risk and an allocation of the future purchasing power risk of the money supply according to the willingness of investors to bear this risk in exchange for return and without regard for investor needs for the future transactions services of money in open

natural resource booms and inequality theory and evidence we develop a theory in the context of a two sector growth model in which learning by doing drives growth to explain the time path of income inequality following natural resource booms in resource rich countries under the condition of a relatively unskilled labor intensive non traded sector inequality falls immediately after a boom and then increases steadily over time until the initial impact of the boom disappears using data for 90 countries between 1965 and 1999 we find evidence in support of the theory especially for oil and mineral booms we also find that uncertainty about future commodity prices increases long run inequality

resource shocks and human capital stocks brain drain or brain gain abstract based on the paradox of plenty resource abundant countries tend to be vulnerable for lower economic prosperity along with instable political institutions as well as corruption this paper sheds light on the relationship between resource abundance and the selectivity of migration first i combine a dutch disease model with a roy borjas model in order to elaborate on the relationship between resource shocks and migrant selectivity theoretically thereby i predict that resource booms give rise to brain drain effects which are mediated through distributional effects under certain conditions second i provide empirical evidence for the effect of resource shocks on migrant selectivity based on a structural equation model in order to disentangle effects on income inequality and migrant selectivity the results show that resource shocks especially oil booms strengthen brain drain effects in a sample with 116 source and 23 destination countries between 1910 and 2009

currency prices terms of trade and interest rates a general equilibrium asset pricing cash in advance approach currency prices terms of trade and interest rates a general equilibrium asset pricing cash in advance approach

an empirical investigation of international asset pricing we investigate several asset pricing models in an international setting we use data on a large number of assets traded in the united states japan the united kingdom and france the models together with the hypothesis of capital market integration imply testable restrictions on multivariate regressions relating asset returns to various benchmark portfolios we find that multifactor models tend to outperform single index models in both domestic and international forms especially in their ability to explain seasonality in asset returns we also find that the behavior of the models is affected by changes in the regulatory environment in international markets

why do some resource abundant countries succeed while others do not on average resource abundant countries have experienced lower growth over the last four decades than their resource poor counterparts but the most interesting aspect of the paradox of plenty is not the average effect of natural resources but its variation for every nigeria or venezuela there is a norway or a botswana why do natural resources induce prosperity in some countries but stagnation in others this paper gives an overview of the dimensions along which resource abundant winners and losers differ in light of this it then discusses different theory models of the resource curse with a particular emphasis on recent developments

on the effects of barriers to international investment a simple model is presented in which it is costly for domestic investors to hold foreign assets the implications of the model for the composition of optimal portfolios at home and abroad are derived it is shown that all foreign assets with a beta larger than some beta plot on either one of two security market lines some foreign assets with a beta smaller than are not held by domestic investors even if their expected return is increased slightly while it is obviously not true that asset markets are completely segmented between countries there is evidence of barriers to international investment although reality seems to lie in that grey area between complete segmentation and no segmentation at all most international asset pricing models are concerned with the extreme case of no barriers to international investment no effort seems to have been made to study the effect on portfolio choice of such barriers which make it costly to hold foreign securities as opposed to domestic securities but which do not in general render international diversification so onerous that investors avoid foreign securities completely casual empiricism suggests that models without barriers to international investment should be suspect those models cannot explain why it appears that in every country investors on average hold more domestic securities than would be required if they held the world market portfolio 2 this paper constructs a model of international asset pricing in which there is a cost associated with holding either long or short risky foreign securities for the sake of simplicity in most of the paper we assume that while domestic investors face barriers to international investment foreign investors face no such barriers it turns out that nothing significant is lost with such an assumption the main conclusions of this paper for the case in which foreign investors face no barriers to international investment are 1 in the presence of barriers to international investment some risky foreign

the consumption based asset pricing model a note on potential tests and applications abstract breeden s demonstration that merton s multi beta capital asset pricing model can be collapsed into a single beta model where betas are computed with respect to aggregate consumption is an important theoretical advance nonetheless breeden s model retains many of the empirical problems that beset merton s earlier version in general the consumption betas will be nonstationary so that the state variables must be observable for the model to be estimated

taxation in papua new guinea backwards to the future abstract this paper explores the evolution current problems and possible future developments of the tax system of papua new guinea leaving aside the important question of natural resource taxation the paper concludes that there is at present a serious mismatch between the nature of papua new guinea s economy and its taxes in particular taxation must be extended to reach the bulk of economic activity in the country no matter what is done in this respect however papua new guinea is most unlikely to be able to finance its current level of government expenditure in the absence of additional aid or natural resource revenue the major public sector problem confronting the country is therefore not tax reform but expenditure reform

current account norms in natural resource rich and capital scarce economies abstract the permanent income hypothesis implies that frictionless open economies with exhaustible natural resources should save abroad most of their resource windfalls and therefore feature current account surpluses resource rich developing countries rrdcs on the other hand face substantial development needs and tight external borrowing constraints by relaxing these constraints and providing a key financing source for public investment resource windfalls might then be associated with current account deficits or at least low surpluses in this paper we develop a neoclassical model with private and public investment and several pervasive features in rrdcs including absorptive capacity constraints inefficiencies in investment borrowing constraints and capital scarcity we use the model to study the role of investment and these frictions in shaping the current account dynamics under windfalls since consumption and investment decisions are optimal the model also serves to analyze current account norms benchmarks we apply the model to the economic and monetary community of central africa and discuss how our results can be used to inform external sustainability analyses in rrdcs

resource intensity institutions and development summary we examine the relationship between resource abundance and several indicators of human welfare consistent with the existing literature on the relationship between resource abundance and economic growth we find that given an initial income level resource intensive countries tend to suffer lower levels of human development while we find only weak support for a direct link between resources and welfare there is an indirect link that operates through institutional quality there are also significant differences in the effects that resources have on different measures of institutional quality these results imply that the resource curse is a more encompassing phenomenon than previously considered and that key differences exist between the effects of different resource types on various aspects of governance and human welfare 2005 elsevier ltd all rights reserved

the dutch disease a disease after all many third world oil producers are encountering serious problems in building up a diversified export base while west european oil and gas producers netherlands united kingdom are suffering a decline in their traded goods manufacturing sector induced by real wage pressures it is becoming increasingly clear that high but temporary oil revenues may be somewhat ora mixed blessing the quip of the economist notwithstanding the mechanism behind this unbalance is clear enough part of the oil revenues is spent on non traded goods which leads to a real appreciation i e a rise in the relative price of non traded goods in terms of traded goods this in turn draws resources out of the non oil traded sector into the non traded goods producing sector corden and neary 1982 van wijnbergen 1980 one may say that this is an efficient response to the increase in income from oil production the united kingdom mexico egypt simply should move into oil derived industries and non traded goods and forget about their manufacturing sector until oil reserves are exhausted however many developing countries are hesitant to take this advice after all the post world war ii success stories in economic development involve without exception countries that promoted their traded goods sector aggressively moreover it is a well established stylised fact that technological progress is faster in the traded non sheltered sectors of an economy than in the non traded sector balassa 1964 is an early reference considering the hypothesis that technological progress rather than taking place exogenously with the passage of time is a function of accumulated experience the concern of countries like egypt mexico or indonesia is much easier to understand since solow 1957 and denison 1962 it is known that capital accumulation explain only a small part of economic growth if most of economic growth is caused by learning by doing induced technologica

the relation between stock prices and inflationary expectations the international evidence this paper provides empirical evidence on the relation between stock returns and inflationary expectations for nine countries over the period 1971 80 the fisherian assumption that real returns are independent of inflationary expectations is soundly rejected for each major stock market of the world using interest rates as a proxy for expected inflation our data provide consistent support for the geske and roll model whose basic hypothesis is that stock price movements signal negative revisions in inflationary expectations finally a weak real interest rate effect was found for some of these countries

a theory of infrastructure led development abstract this paper proposes a theory of long run development based on public infrastructure as the engine of growth the government in addition to investing in infrastructure spends on health services which in turn raise labor productivity and lower the rate of time preference infrastructure affects the production of both commodities and health services as a result of network effects the degree of efficiency of infrastructure is nonlinearly related to the stock of public capital itself provided that governance is adequate enough to ensure a sufficient degree of efficiency of public investment an increase in the share of spending on infrastructure financed by a cut in unproductive expenditure or foreign grants may facilitate the shift from a low growth equilibrium characterized by low productivity and low savings to a high growth steady state

commodity prices and growth an empirical investigation whereas empirical evidence on the effect of higher commodity prices on the long run growth of commodity exporters is ambiguous time series analyses using vector autoregressive var models have found that commodity booms raise income in the short run in this paper we adopt panel error correction methodology to analyze global data for 1963 to 2008 to disentangle the short and long run effects of international commodity prices on output per capita our results show that commodity booms have unconditional positive short term effects on output but non agricultural booms in countries with poor governance have adverse long term effects which dominate the short run gains our findings have important implications for non agricultural commodity exporters with poor governance especially in light of the recent wave of resource discoveries in low income countries

optimal fiscal management of commodity price shocks abstract this paper analyzes how low income countries should optimally respond through fiscal policy to commodity price shocks the model accounts for imperfect access to world capital markets and a variety of externalities associated with public infrastructure including utility benefits a direct complementarity effect with private investment and reduced distribution costs however public capital is also subject to congestion and absorption constraints with the latter affecting the efficiency of infrastructure investment the optimal windfall allocation rule between spending today and asset accumulation is determined so as to minimize a social loss function defined in terms of the volatility of private consumption and either the nonresource primary fiscal balance or a more general index of macroeconomic stability which accounts for the volatility of the real exchange rate

futures markets and commodity options hedging and optimality in incomplete markets abstract this paper examines the allocational roles of futures markets and commodity options in multi good and multi period economies in a continuous time model with time additive utilities and homogeneous beliefs trading in unconditional futures contracts the market portfolio and a riskless asset gives any pareto optimal allocation individuals optimal holdings of futures contracts in the continuous time model are related to their consumption bundles and to their risk tolerances it is shown that both hedging and reverse hedging behavior are possible in the general model with discrete trading options on portfolios of commodity options are shown to permit any unconstrained pareto optimal allocation

pricing capital assets in an international setting an introduction this paper shows how differences across countries of 1 inflation rates 2 consumption baskets of investors and 3 investment opportunity sets of investors matter when one applies capital asset pricing models in an international setting in particular the fact that countries differ is shown to affect the portfolio held by investors the equilibrium expected returns of risky assets and the financial policies of firms

cursed by resources or institutions natural resource abundant countries constitute both growth losers and growth winners and the main difference between the success cases and the cases of failure lays in the quality of institutions with grabber friendly institutions more natural resources push aggregate income down while with producer friendly institutions more natural resources increase income such a theory finds strong support in data a key question we also discuss is if resources in addition alter the quality of institutions when that is the case countries with bad institutions suffer a double resource curse as the deterioration of institutions strenghtens the negative effect of more natural resources

using natural resources for development why has it proven so difficult developing economies have found it hard to use natural resource wealth to improve their economic performance utilizing resource endowments is a multistage economic and political problem that requires private investment to discover and extract the resource fiscal regimes to capture revenue judicious spending and investment decisions and policies to manage volatility and mitigate adverse impacts on the rest of the economy experience is mixed with some successes such as botswana and malaysia and more failures this paper reviews the challenges that are faced in successfully managing resource wealth the evidence on country performance and the reasons for disappointing results

international asset pricing with time varying risk premia abstract recent empirical evidence that forward exchange rates are biased predictors of future spot rates can also be interpreted as evidence against the hypothesis of a constant risk premium consequently reconciliation of this evidence with efficient international capital markets requires the existence of time varying risk premia this paper modifies kouri s 1977 asset pricing model to allow time varying exected returns on assets eliminates the assumption of a risk free real asset and derives the characteristics of the risk premia in the forward market as well as the equilibrium yield relationships among the equities and riskless nominal bonds of all countries

government finance in the wake of currency crises we address three questions i can classical models be reconciled with the fact that many crises are marked by high rates of depreciation and small increases in seignorage revenue ii what are the implications of different financing methods for post crisis rates of inflation and depreciation iii how do governments pay for the fiscal costs associated with currency crises to study these questions we use a general equilibrium model in which prospective government deficits trigger a currency crisis we then use our model in conjunction with fiscal data to interpret government financing in the wake of three recent currency crises korea 1997 mexico 1994 and turkey 2001

investment composition and international business cycles abstract this paper studies a two country model with traded and nontraded sectors in which sector specific capital goods as in practice are produced by combining inputs from all sectors the model also includes nontraded distribution services employed in retailing traded goods to consumers the results show that the model with capital goods comprising multisectoral inputs outperforms the standard model in which sectoral output also serves as its capital in particular it substantially improves a the movements of trade balance and relative prices b within country comovements of sectoral and aggregate quantities c cross country comovements of output vis a vis consumption the results change only marginally when distribution services are removed from the model

harnessing windfall revenues optimal policies for resource rich developing economies a windfall of natural resource revenue or foreign aid faces government with choices of how to manage public debt investment and the distribution of funds for consumption particularly if the windfall is both anticipated and temporary we show that the permanent income hypothesis prescription of an ever lasting increase in consumption financed by borrowing ahead of the windfall and then accumulating a sovereign wealth fund swf is not optimal for capital scarce developing economies such countries should accumulate public and private capital to accelerate their development and only if the windfall is large relative to initial foreign debt is it optimal to build a swf the optimal time profile of consumption is biased towards the near future as compared to the permanent income hypothesis outcomes depend on instruments available to government we study cases where the government can make lump sum transfers to consumers where such transfers are impossible so optimal policy involves cutting distortionary taxation in order to raise investment and wages and where ricardian consumers can borrow against future revenues in which case the policy response to possible over consumption is a high level of investment in infrastructure

the narrow moving band the dutch disease and the competitive consequences of mrs thatcher notes on trade in the presence of dynamic scale economies abstract this paper presents a model of trade in which comparative advantage instead of being determined by underlying attributes of countries evolves over time through learning by doing in this model arbitrary patterns of specialization once established tend to become entrenched over time the model sheds light on three widely held views that do not make sense in more conventional models first is the view that temporary protection of selected sectors can permanently alter the pattern of comparative advantage in the protecting country s favor second is the view that seemingly favorable developments such as the discovery of exportable natural resources may lead to a permanent loss of other sectors and reduce welfare in the long run third is the possibility that a temporary overvaluation of a currency due to tight money can lead to a permanent loss of competitiveness in some sectors

natural resources rent seeking and welfare abstract a new and very simple mechanism to explain why natural resource abundance may lower income and welfare is developed in a model with rent seeking a greater amount of natural resources increases the number of entrepreneurs engaged in rent seeking and reduces the number of entrepreneurs running productive firms with a demand externality it is shown that the drop in income as a result of this is higher than the increase in income from the natural resource more natural resources thus lead to lower welfare

inflation employment and the dutch disease in oil exporting countries a short run disequilibrium analysis the author uses nontraded goods and labor shortages in the gulf countries the decline of the traded goods sector in oil producers dutch disease and the absence of employment benefits of higher oil revenues in latin american oil producers higher oil revenues can be likened to a transfer putting pressure on non oil traded nt goods prices and drawing resources out of the t sector the slope of the wage indexation line determines whether classical unemployment or repressed inflation results various policy measures are analyzed 3 references 8 figures

booming sector and de industrialisation in a small open economy this paper presents a theoretical analysis of the dutch disease the phenomenon whereby a boom in one traded goods sector squeezes porfitability in other traded goods sectors both by directly bi

institutions and the resource curse countries rich in natural resources constitute both growth losers and growth winners we claim that the main reason for these diverging experiences is differences in the quality of institutions more natural resources push aggregate income down when institutions are grabber friendly while more resources raise income when institutions are producer friendly we test this theory building on sachs and warner s influential works on the resource curse our main hypothesis that institutions are decisive for the resource curse is confirmed our results contrast the claims of sachs and warner that institutions do not play a role

carbon curse in developed countries among the ten countries with the highest carbon intensity six are natural resource rich countries this suggests the existence of a carbon curse resource rich countries would tend to follow more carbon intensive development paths than resource poor countries we investigate this assumption empirically using a panel data method covering 29 countries oecd and bric and seven sectors over the 1995 2009 period first at the macroeconomic level we find that the relationship between national co 2 emissions per unit of gdp and abundance in natural resources is u shaped the carbon curse appears only after the turning point second we measure the impact of resource abundance on sectoral emissions for two groups of countries based on their resource endowments we show that a country rich in natural resources pollutes relatively more in resource related sectors as well as all other sectors our results suggest that the debate on climate change mitigation should rather focus on a comparison of resource rich countries versus resource poor countries than the developed country versus developing country debate

additional evidence on integration in the canadian stock market this paper reexamines the integration of the canadian and u s stock markets in the 1977 86 period that is relatively free from capital controls the study employs both the capm and the apt frameworks under both models the evidence is consistent with segmentation in the 1977 81 subperiod but supports integration in the 1982 86 subperiod using the apt framework we also find that the canadian stocks interlisted on the u s exchanges and nasdaq are priced in an integrated market and segmentation is predominant for the non interlisted canadian stocks in a study using an international capm framework jorion and schwartz 1986 find strong evidence of segmentation in the pricing of canadian stocks relative to a north american market comprising the canadian and u s stock markets the rejection of integration holds for canadian stocks that are interlisted on the u s stock exchanges and nasdaq as well as for domestic canadian stocks that are listed only on the canadian stock exchanges their results are surprising since the canadian and u s economies are highly integrated and the structure and regulation of security markets in the two countries are similar as well the canadian stocks interlisted on the u s stock exchanges list under the same regulation as the domestic u s stocks thus ex ante we would expect the canadian and u s stock markets to be integrated especially for the interlisted stocks 1 this study reexamines the integration in the canadian market employing both the capm and the apt frameworks since tests of market integration are joint tests of a specified model and market integration a relevant question is whether the two models produce different inferences pertaining to the integration issue in addition we explore this issue in a period that is

fixed capital stock depreciation in developing countries some evidence from firm level data previous growth accounting studies suggest severe capital underutilisation and mismeasurement of the stocks of capital in some developing countries using the firm level data sets from the world ba

learning by doing and the dutch disease this paper develops a model of learning by doing and the dutch disease that extends the earlier literature in two ways first it is assumed that both the traded and the non traded sector can contribute to learning second it is assumed that there are learning spillovers between the sectors it is shown that within such a model a foreign exchange gift results in a real exchange rate depreciation in the long run due to a shift in the steady state relative productivity between the traded and the non traded sector in contrast to standard models of the dutch disease production and productivity in both sectors may go up or down the conditions for the different cases are worked out

dutch disease and the mitigation effect of migration evidence from canadian provinces this article evaluates whether immigration can mitigate the dutch disease effects associated with booms in natural resource sectors we derive predicted changes in the size of the non tradable sector from a small general equilibrium model a la obstfeld rogoff using data for canadian provinces we find evidence that aggregate immigration mitigates the increase in the size of the non tradable sector in booming regions the mitigation effect is due mostly to interprovincial migration and temporary foreign workers there is no evidence of such an effect for permanent international immigration interprovincial migration also results in a spreading effect of dutch disease from booming to non booming provinces

is it risk explaining deviations from uncovered interest parity abstract this paper analyzes ex ante returns to forward speculation and asks if these returns can be explained by models of a foreign exchange risk premium after presenting evidence that both nominal and real expected speculative profits are nonzero the paper examines if real returns to forward speculation are consistent with consumption based models of risk premia estimates of the conditional covariance between real speculative returns and real consumption growth are presented and like ex ante returns to forward speculation they exhibit statistically significant fluctuations over time and often change sign

a new look at indirect taxation in developing countries abstract this paper reconsiders some of the traditional arguments made against indirect taxes on consumption such taxes despite the extensive criticism to which they have been subjected in the academic literature remain the mainstay of public finance in most developing countries and are likely to continue to do so brief discussions of the design of excise taxes and the incidence of indirect taxes on the poor illustrate the sorts of issues where more detailed tax specific and country specific research is needed to replace conventional generalizations about the effects of indirect taxes

roads out of poverty assessing the links between aid public investment growth and poverty reduction the authors develop a macroeconomic framework that captures links between aid public investment growth and poverty public investment is disaggregated into education infrastructure and health and affects both aggregate supply and demand dutch disease effects are captured by accounting for changes in the relative price of domestic goods the authors assess the impact of policy shocks on poverty by linking the model to a household survey they calibrate the model for ethiopia and simulate the changes in the allocation of aid and public investment the authors also calculate the amount by which foreign aid should increase to reach the poverty targets of the millennium development goals

us money supply announcements and pacific rim stock markets evidence and implications this paper documents variation across pacific rim countries in the response of equity values to us m1 announcement suprises we relate the difference across countries to measures of capital mobility export trade with the usa foreign exchange and money market arrangements and correlation with the us stock market we find that the response to us m1 suprises is best explained by the country s degree of integration with international capital markets the flexibility of the exchange rate and interest rates may also be significant while the evidence is supportive of the anticipated fed reaction theory of the effect of money announcement suprises the differing response ro m1 shocks across fed policy regimes remains unexplained

the demand for foreign bonds this paper derives the demand for foreign bonds in a simple general equilibrium model in which the exchange rate is perfectly correlated with the terms of trade a necessary condition for the demand for foreign bonds to be an increasing function of the domestic currency value of imports is derived earlier work shows that the demand for foreign bonds is an increasing function of imports if the domestic investor s degree of relative risk tolerance is smaller than one the present paper shows that the demand for foreign bonds can be a decreasing function of imports if the degree of relative risk tolerance is smaller than one when the consumption expenditure elasticity of imports exceeds one

political foundations of the resource curse in this paper we argue that the political incentives that resource endowments generate are the key to understanding whether or not they are a curse we show 1 politicians tend to over extract natural resources relative to the efficient extraction path because they discount the future too much and 2 resource booms improve the efficiency of the extraction path however 3 resource booms by raising the value of being in power and by providing politicians with more resources which they can use to influence the outcome of elections increase resource misallocation in the rest of the economy 4 the overall impact of resource booms on the economy depends critically on institutions since these determine the extent to which political incentives map into policy outcomes countries with institutions that promote accountability and state competence will tend to benefit from resource booms since these institutions ameliorate the perverse political incentives that such booms create countries without such institutions however may suffer from a resource curse

resource discoveries and excessive external borrowing this paper incorporates a three sector dutch disease model into the overlapping generations framework of o blanchard 1985 it is shown that if the extraction of natural resources is capital intensive then a resource discovery may shift income away from labor if this happens then the asset holders at the time of the discovery will incur such a large debt that in order to pay the interest on the debt aggregate expenditure in the new steady state would have to be smaller than it was before the resource discovery the country may then experience both real depreciation and proindustrialization copyright 1991 by royal economic society

aid investment and incentives promoting productive investment and economic growth are among the key objectives of most aid organizations operating in poor countries however it is not possible to conclude from existing empirical evidence that aid contributes positively to growth in this paper it is shown that those rather negative results may be explained by important incentive problems built into the aid system itself the recipient countries own efforts to contribute to investment and growth may in reality be undermined and the result may be aid dependency

funds from non renewable energy resources policy lessons from alaska and alberta abstract we document the use of energy natural resource funds in alaska and alberta and analyze theirs characteristics for further implementation in resource rich countries such funds allow dealing theoretically with intergenerational equity issues corruption and more general institutional problems the performance of both funds is very different depending on the management and composition choices but some policy lessons can be drawn from these two examples importantly the role of a public dividend policy is highlighted as a way to bypass corrupted institutions and to enhance quality of life for poorest people we also emphasize the need to deal with inflation to make the fund sustainable

globalization taxation and burden shifting in latin america most researchers interested in the relationship between global markets and public policy focus on advanced industrial democracies in contrast we examine competing hypotheses as to globalization s effect on governments by expanding the scope of the discussion to include developing nations more specifically we investigate the relationship between international market integration and the evolving burden of taxation on capital as well as the subsequent response of markets to shifts in tax policy in latin america since the late 1970s consistent with our theoretical expectations we find that global market forces are more constraining vis a vis tax policy in latin america than in the world s wealthiest nations despite these market based pressures however national politics continue to influence tax policy in latin america in a manner consistent with findings on advanced industrial democracies as such developing nations continue to have some room to manipulate policy though within the context of a more strictly neoliberal context than their counterparts in advanced industrial democracies

what have we learned from three decades of research on the productivity of public capital the last three decades have witnessed a great deal of research effort devoted to measuring the private output elasticity of public capital the wide range of available estimates have precluded any consensus so far however this paper reconciles the empirical findings of the literature by quantitatively analyzing a sample of 578 estimates collected from 68 studies for the 1983 2008 period using meta regression analysis we show how study design characteristics and publication bias can explain a large fraction of the variation across estimates we find a short run output elasticity of public capital supplied at the central government level of 0 083 which increases to 0 122 in the long run if in addition only core infrastructure at a regional local level of government is considered these estimates are almost doubled the average output elasticity of public capital amounts to 0 106 our results suggest that public capital is undersupplied in oecd economies

aid and the supply side public investment export performance and dutch disease in low income countries contemporary policy debates on the macroeconomics of aid often concentrate on short run dutch disease effects ignoring the possible supply side impact of aid financed public expenditure in the simple model of aid and public expenditure presented here public infrastructure generates an inter temporal productivity spillover which may exhibit a sector specific bias the model also provides for a learning by doing externality through which total factor productivity in the tradable sector is an increasing function of past export volumes an extended computable version of this model is used to simulate the effect of a step increase in net aid flows the simulations show that beyond the short run when conventional demand side dutch disease effects are present the relationship between enhanced aid flows and real exchange rates output growth and welfare is less straightforward than simple models of aid suggest public infrastructure investment that generates a productivity bias in favor of non tradable production delivers the largest aggregate return to aid but at the cost of deterioration in the income distribution income gains accrue predominantly to skilled and unskilled urban households leaving the rural poor relatively worse off under plausible parameterizations of the model the rural poor may also be worse off in absolute terms
