risk and return in an equilibrium apt application of a new test methodology abstract we use an asymptotic principal components technique to estimate the pervasive factors influencing asset returns and to test the restrictions imposed by static and intertemporal equilibrium versions of the arbitrage pricing theory apt on a multivariate regression model the empirical techniques allow for fairly arbitrary time variation in risk premiums we find that the apt provides a better description of the expected returns on assets than the capital asset pricing model capm however some statistically reliable mispricing of assets by the apt remains

from evidence to calibration for starting point bias willingness to pay for treated mosquito nets in gujarat india this study uses a bidding format to assess households willingness to pay wtp for treated mosquito nets tmns it tests for starting point bias by allocating respondents randomly to three different starting bids rs 50 rs 75 and rs 100 and following this response with one further closed bid offer and a final open ended wtp question there is a clear presence of starting point bias by undertaking a simulated market experiment sme this study attempts to measure the magnitude and direction of the bias so that the necessary calibration factor can be calculated with which to adjust the mean willingness to pay value it was observed that the true mean wtp adjusted for starting point bias rs 56 26 is not very different from the unadjusted mean wtp of rs 57 38 it is concluded that the presence of starting point bias even in carefully designed wtp studies using a bidding format cannot be ruled out however the existence of starting point bias itself does not reflect the magnitude of the problem it

aid and growth what meta analysis reveals abstract recent literature in the meta analysis category where results from a range of studies are brought together throws doubt on the ability of foreign aid to foster economic growth and development this article assesses what meta analysis has to contribute to the literature on the effectiveness of foreign aid in terms of growth impact we re examine key hypotheses and find that the effect of aid on growth is positive and statistically significant this significant effect is genuine and not an artefact of publication selection we also show why our results differ from those published elsewhere

do subjects remember the past in many experiments experimenters use the random lottery incentive mechanism and ask many questions to each subject that is at the end of the experiment just one of the questions is picked at random and the subject paid on the basis of their answer to this one question the idea is that subjects should separate the various questions and reply to each as if it were a separate question this procedure is methodologically sound if the subjects preferences obey expected utility eu theory which implies a form of separation but if they do not this incentive mechanism is open to criticism indeed many referees use this argument against the research they argue that subjects do not consider questions separately if the questions are revealed to the subjects one by one then the appropriate alternative hypothesis is that their behaviour evolves with the questions here this hypothesis is tested that the questions already answered affect the answers to the subsequent questions the analysis shows that

aid policy and growth in post conflict societies countries emerging from civil war attract both aid and policy advice this paper provides the first systematic empirical analysis of aid and policy reform in the post conflict growth process it is based on a comprehensive data set of large civil wars and covers 27 countries that were in their first decade of post conflict economic recovery during the 1990s the authors first investigate whether the absorptive capacity for aid is systematically different in post conflict countries they find that during the first three post conflict years absorptive capacity is no greater than normal but that in the rest of the first decade it is approximately double its normal level so ideally aid should phase in during the decade historically aid has not on average been higher in post conflict societies and it has tended to taper out over the course of the decade the authors then investigate whether the contribution of policy to growth is systematically different in post conflict countries and in particular whether particular components of policy are differentially important for this they use the world bank policy rating database the authors find that growth is more sensitive to policy in post conflict societies comparing the efficacy of different policies they find that social policies are differentially important relative to macroeconomic policies however historically this does not appear to have been how policy reform has been prioritized in post conflict societies

policy variability and economic growth this paper explores the effect of policy variability or frequency of regime switching on economic growth and welfare we study a one sector growth model where investment can be subsidized at either a positive rate or not subsidized at all we find that the lack of persistence in policies per se need not be welfare reducing and that it is likely to decrease growth higher variability implies more frequent changes in consumption and investment but by creating a stronger intertemporal link across regimes variability reduces the fluctuation in investment rates thus decreasing the magnitude of changes in consumption and increasing welfare

risk taking global diversification and growth this paper develops a continuous time stochastic model in which international risk sharing can yield substantial welfare gains through its effect on expected consumption growth the mechanism linking global diversification to growth is an attendant world portfolio shift from safe low yield capital to riskier high yield capital the presence of these two types of capital captures the idea that growth depends on the availability of an ever increasing array of specialized hence inherently risky production inputs calibration exercises using consumption and stock market data imply that most countries reap large steady state welfare gains from global financial integration copyright 1994 by american economic association

cursing the blessings natural resource abundance institutions and economic growth summary since sachs and warner s sachs j d warner a m 1995a natural resource abundance and economic growth nber working paper no 5398 contribution there has been a lively debate on the so called natural resource curse this paper re examines the effects of natural resource abundance on economic growth using new measures of resource endowment and considering the role of institutional quality we find a positive direct empirical relationship between natural resource abundance and economic growth in both ols and 2sls regressions the positive resource effects are particularly strong for subsoil wealth our results also show no evidence of negative indirect effects of natural resources through the institutional channel

market access conditions and sub saharan africa s exports diversification summary despite some progress in the last decade sub saharan africa s participation in the global economy remains generally limited and poorly diversified among the various reasons behind the lack of competitiveness of sub saharan africa exports this paper analyzes whether changes in market access conditions affect export diversification the findings of this paper indicate that market access conditions remain important and that the presence of trade relationships depends not only on favorable market access conditions but also on how these compare relative to foreign competitors these results imply that freer trade within sub saharan african countries could provide significant incentive to intra regional trade

weather variations and international trade in this paper i investigate the effect of weather variations in the exporter and importer countries separately as well as a the difference between weather variations in both countries on bilateral trade flows the analysis is done at the country sectoral and product levels worldwide and over the 1992 2014 period i find a negative effect of temperature variations in the exporter country and in the difference between exporter and importer countries on bilateral trade at the country level at the product level both negative and positive effects arise but the negative effect of temperature dominates the temperature effects are on the agricultural and manufacturing sectors especially in the textile and metals sectors i show that possible channels are the impact of temperature on output and labour productivity the negative impacts are larger in exporter countries that are closer to the equator that have lower quality of institutions and that export to more remote countries if countries are able to adapt to climate change the long term effects of temperature variations should be lower than the contemporaneous effect nevertheless my results on the long term effects analysis do not support this hypothesis suggesting no or very low adaptation moreover the negative effect of temperature is persistent and cumulative through several years after the temperature shock concerning precipitation variation effects they are found mainly at the product level with the positive effect dominating for the affected products

export product diversification and co2 emissions contextual evidences from developing and developed economies abstract ascertaining cleaner production and sustainability is a major issue in the developed and developing world income and international trade are the predominant factors behind this this article explores the heterogeneous impacts of export product diversification extensive margin and intensive margins on the co2 emissions for developing and developed countries to this end the authors analyze the annual data of variables from 1971 to 2014 and employ unrestricted fixed effects and system gmm to solve the research problem the empirics suggest that all three indicators of export diversification significantly reduce co2 emissions in 63 developed and developing countries as a global sample the fixed effect models reveal that product diversification and intensive margin have a negative and significant impact in developed economies the negative impacts of product diversification show that economic sophistication is an important tool to reduce emissions further the chow test proved the statistical difference between developed and developing economies which contributes to policy recommendations based on the empirical outcomes the study suggests innovative policies for cleaner production and industrial manufacturing purposes making the policies more effective in achieving sustainable development goals sdgs

want export diversification educate the kids first this paper uses bayesian model averaging to uncover the true determinants of export diversification among 36 potential factors and thus 236 potential models using data from 2001 to 2010 our results reveal two strong predictors primary school enrollment 99 7 posterior inclusion probability in the true model raises export diversification whereas the share of natural resources in gross domestic product 98 6 lowers diversification levels the importance of basic education coverage offers policymakers an opening toward diversifying exports at least in the long run this result is robust to accounting for the endogeneity of income levels by applying an instrumental variable bma method jel c11 f1 f34 o1 o2 o11

if diversification is good why don t countries diversify more the political economy of diversification in resource rich countries abstract for resource rich countries diversification is claimed to represent a strategy for reducing resource curse problems this however depends on whether diversification has a positive effect on the country s institutions while there is a lot of evidence that exports of oil have a negative impact on institutions we know much less about the extent to which diversification leads to better institutions this article applies recent political economy theory to the phenomenon of diversification theoretical arguments suggest that it is the pattern of industrial activity rather than diversification per se which affects institutions like democracy in other words not all forms of diversification lead to better institutions furthermore where diversification has a positive impact on institutions diversification may be difficult to attain when it threatens the power base of the ruling elite a possible implication of these arguments is that policies for diversification should focus on international regulation affecting elite incentives rather than domestic industrial policy

e baying for blood noncompetitive flexible pricing in entertainment ticketing some demand side evidence this article gives some exploratory results from estimating a consumer surplus type equation which features a number of economic and demographic variables as regressors we calculate an income elasticity for the maximum surplus that individuals would ever perceive themselves to be getting by being allowed to buy at a set price the results also show that those who attend the cinema are significantly less inclined to generate a surplus in flexible price events markets whilst young adults offer to pay quite a large amount more for their heavily desired entertainment this suggests that part of the burden of a shift in ticket pricing methods may be borne by the parents of young adults

the surprising instability of export specializations abstract we study the instability of hyper specialization of exports at the 4 digit level in 1998 2010 1 specializations are surprisingly un stable export ranks are not persistent and new top products and destinations replace old ones measurement error is unlikely to be the main or only determinant of this pattern 2 source country factors are not the main explanation of this instability only 16 20 of variation in export growth is accounted for by source country plus source country product factors that do not vary across destinations the high share of idiosyncratic variance source product destination residual of 41 55 indicates the difficulty to predict export success using source country characteristics while we are cautious in interpreting factors that are jointly determined in global general equilibrium our results suggest that destination and product specific factors importantly matter at least as much as source country factors

does industrial structure explain the benefits of international diversification abstract we examine the influence of industrial structure on the cross sectional volatility and correlation structure of country index returns for 12 european countries between 1978 and 1992 we find that industrial structure explains very little of the cross sectional difference in country return volatility and that the low correlation between country indices is almost completely due to country specific sources of return variation diversification across countries within an industry is a much more effective tool for risk reduction than industry diversification within a country

recursos naturales diversificacion y crecimiento regional en el peru based upon the export product space this paper shows the main features of the export product composition of peru and its regions with respect to export baskets these include a high con centration in few commodities a relatively low degree of similarity between products relatively high levels of productivity at the international level and enormous undiscovered or untapped export potential in addition this paper analyzes the hypothesis that the natural resource curse affects regional growth employment and export diversification subject to the limitations of the data and the heterogeneous panel methods employed estimation results indicate that the share of natural capital out of the total tangible wealth and natural capital per capita seems on average and in a relatively statistically robust way to spur growth primary employment and export concentration in a few products consequently the natural resource curse for the peruvian regions is not about growth but about low regional development since such resources do not have a significant impact on secondary and tertiary employment or on export product diversification

democracy diversification and growth reversals there exists convincing evidence that democratic countries are less volatile this conclusion is usually reached with respect to volatility as measured by the standard deviation of annual growth rates of per capita gdp which includes both low and high frequency fluctuations however recently several studies have documented that significant changes in trend growth such as growth accelerations that last a decade or similar periods of negative growth are quite common in this paper we ask whether democracy also has a stabilizing effect on trend volatility i e whether more democratic countries experience fewer and milder swings of trend growth we find a common phenomenon medium term reversals of growth that is periods of exceptionally high growth are on average followed by periods of exceptionally low growth and vice versa the propensity to experience large swings of trend growth is not uniform across countries less democratic countries are more susceptible to it when compared with factors commonly associated with volatility such as measures of quality of institutions macroeconomic policies and financial development we find that democracy is the most robust predictor of a country s propensity for growth reversals we construct a model in which non democracies have high barriers of entry for new firms this leads to less sectoral diversification fewer sectors are operated but more resources are channeled to each in an uncertain environment this leads to infrequent but large growth accelerations when one of the few sectors operated is successful however these accelerations are followed by large declines when fortunes change in favor of the missing sectors we present empirical evidence that confirms the positive relationship between democracy and industrial diversification

international business cycles world region and country specific factors the paper investigates the common dynamic properties of business cycle fluctuations across countries regions and the world we employ a bayesian dynamic latent factor model to estimate common components in macroeconomic aggregates output consumption and investment in a 60 country sample covering seven regions of the world the results indicate that a common world factor is an important source of volatility for aggregates in most countries providing evidence for a world business cycle we find that region specific factors play only a minor role in explaining fluctuations in economic activity we also document similarities and differences across regions countries and aggregates jel f41 e32 c11 c32

diversification cones trade costs and factor market linkages abstract this paper finds non uniform differences in the distribution functions of factor usage intensities among 10 rich oecd countries the 10 countries form three distinct groups such that the between group differences are more pronounced than within group differences and capital abundant countries are in capital abundant groups the estimation works even if the same industry codes represent different goods across countries in the data the finding is consistent with the multiple cone factor proportions theory with zero trade costs with each group being one cone an alternative interpretation is non zero trade costs both interpretations imply weak factor market linkages between the countries in different groups

aid policies and growth the authors of this paper use a new database on foreign aid to examine the relationships among foreign aid economic policies and growth of per capita gdp in panel growth regressions for 56 developing countries and 6 four year periods 1970 93 they find that the policies that have a great effect on growth are those related to fiscal surplus inflation and trade openness they construct an index for those three policies and have that index interact with foreign aid they have instruments for both aid and aid interacting with policies they find that aid has a positive impact on growth in developing countries with good fiscal monetary and trade policies in the presence of poor policies aid has no positive effect on growth this result is robust in a variety of specifications which include or exclude middle income countries include or exclude outliers and treat policies as exogenous or endogenous they examine the determinants of policy and find no evidence that aid has systematically affected policies either for good or for ill they estimate an aid allocation equation and show that any tendency for aid to reward good policies has been overwhelmed by donors pursuit of their own strategic interests in a counterfactual they reallocate aid reduce the role of donor interests and increasing the importance of policy such a reallocation would have a large positive effect on developing countries growth rates

stages of diversification this paper studies the evolution of sectoral concentration in relation to the level of per capita income we show that various measures of sectoral concentration follow a u shaped pattern across a wide variety of data sources countries first diversify in the sense that economic activity is spread more equally across sectors but there exists relatively late in the development process a point at which they start specializing again we discuss this finding in light of existing theories of trade and growth which generally predict a monotonic relationship between income and diversification

how does war shock the economy abstract wartime periods have frequently been treated as natural macroeconomic experiments but the international pooled time series evidence presented here shows that the literature has over emphasized the experience of the united states and the united kingdom wars fought exclusively on foreign soil do have marginally higher real output growth than peacetime periods but real growth during all other wars is sharply below peacetime levels evidence for foreign and domestic wars is consistent with monetarist fiscalist and mixed theories of wartime booms

uncertainty capital flows and maturity mismatch abstract this paper explores a how the financial uncertainty generated by volatile international capital flows interacts with maturity mismatch on the balance sheets of nonfinancial firms to increase the volatility of output investment and total factor productivity tfp in emerging market economies i build a model of a small open economy in which financial frictions force firms to fund long term projects with short term debt in response to changes in the level of uncertainty regarding the availability of foreign borrowing firms adjust their long term investment contributing to the volatility of investment and output as well as generating endogenous fluctuations in aggregate productivity using data from a panel of major emerging markets i show that the volatility of portfolio debt flows negatively affects output by dampening investment while the volatility of equity flows which do not generate maturity mismatch has no effect consistent with the mechanism in the model the negative impact of capital flow volatility is larger at low levels of financial development and in industries with longer time to build lags my estimates imply that shocks to capital flow volatility account for one fifth of the excess output volatility of the emerging markets in my sample relative to a set of small open advanced economies

financial development growth and the distribution of income a paradigm is presented in which both the extent of financial intermediation and the rate of economic growth are endogenously determined financial intermediation promotes growth because it allows a higher rate of return to be earned on capital and growth in turn provides the means to implement costly financial structures thus financial intermediation and economic growth are inextricably linked in accord with the goldsmith mckinnon shaw view on economic development the model also generates a development cycle reminiscent of the kuznet hypothesis in particular in the transition from a primitive slow growing economy to a developed fast growing one a nation passes through a stage in which the distribution of wealth across the rich and poor widens

does nation building spur economic growth nation building the allocation of economic aid conditional on military assistance in conflict and post conflict environments has cost the world trillions of dollars over the last half century yet few attempts have been made to quantify the potential economic growth effects for the recipient country from the provision of this aid using a 45 year panel dataset we construct a measure of nation building using a three way interaction term between military assistance economic aid and conflict regime considering that slow growing and problem prone countries may be less likely to receive aid we instrument for economic aid by estimating donor to donee aid flows in a first stage procedure using this approach we find that spending on nation building has positive growth effects during conflict periods but that these effects disappear after conflict jel f3 f4 o5

an empirical inquiry into the role of sectoral diversification in exchange rate regime choice abstract whether sectoral diversification affects the exchange rate regime choice and the mechanisms through which this effect might work are largely unknown this study identifies two mechanisms through which sectoral diversification and exchange rate regime choice may be related namely the external shock absorption and rent seeking mechanisms a direct effect of diversification on regime choice is also hypothesized using a panel dataset covering 91 countries over the period 1985 2006 the paper runs a horse race among these potential channels the results show that diversification is associated with flexible regimes in countries experiencing greater external shocks additionally countries characterized by higher levels of corruption and lower levels of diversification opt for fixed regimes suggesting that a fixed regime may shield the powerful elites from international competition there is also weak evidence of the direct effect of diversification in adopting flexible regimes

economic development as self discovery in the presence of uncertainty about what a country can be good at producing there can be great social value to discovering costs of domestic activities because such discoveries can be easily imitated we develop a general equilibrium framework for a small open economy to clarify the analytical and normative issues we highlight two failures of the laissez faire outcome there is too little investment and entrepreneurship ex ante and too much production diversification ex post optimal policy consists of counteracting these distortions to encourage investments in the modern sector ex ante but to rationalize production ex post we provide some informal evidence on the building blocks of our model

asymmetric shocks among u s states abstract the paper applies a factor model to the study of risk sharing among u s states the factor model makes it possible to disentangle movements in output and consumption due to national regional or state specific business cycles from those due to measurement error the results of the paper suggest that some findings of the previous literature which indicate a substantial amount of inter state risk sharing may be due to the presence of measurement error in output when measurement error is properly taken into account the evidence points towards a lack of inter state smoothing

what determines export diversification in the development process empirical assessment this paper assesses the role played by country specific factors as determinants of relative export diversification using a panel data set for 60 countries and 20 years 1985 2004 we confirm that even after clearing out differences in income per capita cross country variability in the degree of export diversification is significant in general apart from per capita income features influencing the size of accessible markets domestic and foreign are the most relevant and robust determinants of the export diversification process diversification opportunities grow if countries are large and not located far from economic core areas and when barriers to trade are restricted

the evolution of comparative advantage measurement and welfare implications using an industry level dataset of production and trade spanning 75 countries and 5 decades and a fully specied multi sector ricardian model we estimate productivities at sector level and examine how they evolve over time in both developed and developing countries we nd that in both country groups comparative advantage has become weaker productivity grew systematically faster in sectors that were initially at the greater comparative disadvantage the global welfare implications of this phenomenon are signicant relative to the counterfactual scenario in which an individual country s comparative advantage remained the same as in the 1960s and technology in all sectors grew at the same country specic average rate welfare today is 1 9 lower at the median the welfare impact varies greatly across countries ranging from 0 5 to 6 among oecd countries and from 9 to 27 among non oecd countries remarkably for the oecd countries nearly all of the welfare impact is driven by changes in technology in oecd countries and for the non oecd countries nearly all of the welfare impact is driven by changes in technology in non oecd countries

nation building and economic growth nation building the joint provision of economic and military aid in conflict or postconflict areas has been used as an important and expensive foreign policy tool yet despite the huge costs of these investments the growth effects of nation building operations for recipient nations remain underexplored while recent literature documents the negative growth effects of conflict yamarik johnson and compton 2010 and the positive effects of economic aid after conflict collier and hoeffler 2002 very little has been done on the confluence of different kinds of aid and the effectiveness of such joint efforts during times of turmoil this paper attempts to answer the following three questions regarding the growth effects of nation building operations does the joint provision of economic and military assistance help a country grow when it is embroiled in conflict does such joint provision

do all sectoral shocks lead to aggregate volatility empirics from a production network perspective abstract productive diversification has long been acknowledged as a volatility reducing strategy yet recent theoretical contributions have shown that in strongly diversified economies idiosyncratic shocks could translate into aggregate volatility via the network of inter industry linkages by exploiting exogenous cross country sector variations in demand shocks during the 2008 great recession we provide empirical evidence that the network properties of a sector affected by an individual shock determine its propensity to transmit volatility to the rest of the economy more precisely shocks to sectors that are located in denser parts of a production network fade out over a large number of alternative paths of propagation due to substitution effects whereas shocks to sectors that are more influential within the network generate aggregate fluctuations through contagion effects we also find that the impact of sectoral shocks on aggregate volatility 1 is not conditional on sector level differences in trade intensity and 2 is larger for developing countries because they tend to have more isolated influential sectors and larger structural holes in their production network our results thus help consolidate the two opposite views in the literature on the impact of productive diversification on aggregate volatility

does aid for trade diversify the export structure of recipient countries the importance of aid for trade as a tool for facilitating trade economic growth and social development has received attention since the concept was introduced in 2005 while one of the main targets of aid for trade is export diversification reflecting the fact that the exports of many developing countries are concentrated in a small range of items there have not been many efforts to measure the effect of aid for trade on export structure this study therefore attempts to trace the relationship between aid for trade and 133 aid recipients export structure between 1996 and 2013 using the herfindahl hirschman index to measure the degree of export concentration the findings suggest that total aid for trade has reduced the concentration level in the short run in the long run on the other hand aid for trade has had no significant effect on export structure of recipient countries only aid for building productive capacity which is one of the three categories of aid for trade contributes to lower concentration yet this change is not caused by an increase in export diversity but by the redistribution of shares of existing products of a similar sophistication level

caribbean diversification and development small island developing states generally adopt diversification as their primary development strategy often with little success nevertheless there is no empirical study specifically focusing on the pattern of diversification of these countries in relation to their development the objective of this paper was to study the export diversification pattern by the intensive a more equally spread export basket and extensive an increase in new export lines product margin of 21 caribbean countries in relation to their level of development using panel data the results show that despite their limited ability to diversify caribbean countries as has been found for other parts of the world first diversify and subsequently respecialise though at a substantially lower level of income than other countries and that the intensive margin plays a greater role in this process

does product complexity matter for firms output volatility abstract with this paper we provide the first micro level evidence on the linkage between firm complexity and volatility by defining product complexity a la hausmann and hidalgo 2009 we find that a higher complexity level of a firm s product basket is associated to a reduction of its output fluctuations this evidence is robust to the control for omitted variables sample selection and to the use of alternative volatility and complexity indicators across similar firms active in different sectors and regions both technological factors and product market conditions explain the effect of complexity on volatility however within narrowly defined sectors and locations the complexity volatility nexus fully reflects the role of the human capital content of firms product baskets

volatility and slow technology diffusion abstract i study the effects of uncertainty on technology adoption and thereby on volatility and growth i present an analytically tractable model in which i uncertainty about the returns to adoption delays technology diffusion and ii the mean and volatility of output growth are jointly determined in equilibrium i then test the key predictions of the model by studying the introduction of three major information and communication technologies icts computers internet and cell phones i find that countries with more volatile growth rates of real gdp per capita have higher time adoption lags and lower average growth as predicted by the model

variety complexity and economic development abstract we propose a combinatorial model of economic development an economy develops by acquiring new capabilities allowing for the production of an ever greater variety of products with an increasing complexity taking into account that economies abandon the least complex products as they develop over time we show that variety first increases and then decreases in the course of economic development this is consistent with the empirical pattern known as the hump our results question the common association of variety with complexity we further discuss the implications of our model for future research

diversification effects of energy subsidy reform in oil exporters illustrations from kuwait abstract for oil exporters energy subsidy reform and economic diversification are critical policy responses to recent fundamental changes in the global oil market and oil price declines yet the relationship between them is little understood this article investigates linkages between energy subsidy reform and accelerating economic diversification away from hydrocarbons in a low oil price environment using illustrations from kuwait it employs an economy wide general equilibrium model with oligopolistic industrial structure the first of its kind for an economy in the middle east and north africa that embodies unique elements of the country s economic structure oil dependence public sector dominance subsidies sovereign wealth funds industrial collusive pricing behaviour and guest workers the article argues that contrary to common popular discourse kuwait s economy has a diversified economic base but this base fails to diversify export or government revenue needed for economic sustainability results show that weak economic diversification in oil exporters with a similar economic structure is not primarily due to dutch disease as dominant in the literature but to economic constraints and distortions that impair structural change and exacerbate overdependence on hydrocarbons labour and competition reforms relax some constraints achieving large efficiency gains that extend economy wide and can expand non energy tradable sectors the analysis has important policy implications first the potential role of pricing regulation in small economies in moderating economic impacts of negative oil shocks second in oil economies characterized by pervasive oligopolies microeconomic reform can be a channel to achieve efficiency and better diversification effects of subsidy reform

volatility and development why is gdp growth so much more volatile in poor countries than in rich ones we identify four possible reasons i poor countries specialize in more volatile sectors ii poor countries specialize in fewer sectors iii poor countries experience more frequent and more severe aggregate shocks e g from macroeconomic policy and iv poor countries macroeconomic fluctuations are more highly correlated with the shocks of the sectors they specialize in we show how to decompose volatility into these four sources quantify their contribution to aggregate volatility and study how they relate to the stage of development we document the following regularities first as countries develop their productive structure moves from more volatile to less volatile sectors second the level of specialization declines with development at early stages and slowly increases at later stages of development third the volatility of country specific macroeconomic shocks falls with development fourth the covariance between sector specific and country specific shocks does not vary systematically with the level of development we argue that many theories linking volatility and development are not consistent with these findings and suggest new directions for future theoretical work

export diversification what s behind the hump hy should export diversification be taken as a policy objective per se there are two reasons that it should not first according to ricardo countries should specialize not diversify second the heckscher ohlin model implies that export patterns are largely determined by endowments so if anything we should worry about factor accumulation not diversification yet export diversification is a constant preoccupation of policymakers in developing countries as de ferranti et al 2002 note a recurrent preoccupation of latin american policymakers is that their natural riches produce a highly concentrated structure of export revenues which then leads to economic volatility and lower growth p 38 the notion that export patterns are fully determined by endowments is of course naive the relationship of endowments trade and growth is a complex and imperfectly understood one intra industry trade models showed long ago that many factors other than endowments including market failures and policies can affect trade patterns more recently hausmann hwang and rodrik 2007 argued that export patterns can display path dependence in the presence of externalities

geographical disadvantage a heckscher ohlin von thunen model of international specialization abstract we analyse the trade and production patterns of countries located at varying distances from an economic centre exports and imports of final and intermediate goods bear transport costs which increase with distance we show how production and trade depend on factor endowments and factor intensities and also on countries locations and the transport intensities of different goods countries divide into zones with different trade patterns some export oriented and others import substituting we study the implications of distance for factor prices and real incomes the effects of changes in transport costs and the locational choice of new activities

risk sharing and industrial specialization regional and international evidence the authors provide empirical evidence that risk sharing enhances specialization in production to the best of their knowledge this well established and important theoretical proposition has not been tested before the empirical procedure is summarized as follows first the authors construct a measure of specialization in production and calculate an index of specialization for each of the european community ec and non ec oecd countries u s states canadian provinces japanese prefectures latin american countries and regions of italy spain and the united kingdom then they estimate the degree of capital market integration a measure of risk sharing within each of these groups of regions the ec countries the non ec oecd countries the united states canada japan italy spain and the united kingdom and rely on another author s estimate for latin america finally they perform a regression of the specialization index on the degree of risk sharing controlling for relevant economic variables they find a positive and significant relation between the degree of specialization of individual members of a group of countries provinces states or prefectures and the amount of risk that is shared within the group the authors perform regressions using variables such as shareholder rights and the size of the financial sector relative to gdp as instruments for the amount of inter regional risk sharing these regressions confirm that risk sharing facilitated by a favorable legal environment and a developed financial system is a direct causal determinant of industrial specialization this abstract was borrowed from another version of this item

comparative advantage complexity and volatility abstract less developed countries tend to experience higher output volatility a fact that is in part explained by their specialization in more volatile sectors this paper proposes theoretical explanations for this pattern of specialization with the complexity of the goods playing a central role specifically less developed countries with lower institutional ability to enforce contracts or alternately with low levels of human capital will specialize in less complex goods which are also characterized by higher levels of output volatility we provide novel empirical evidence that less complex industries are indeed more volatile

oil windfalls and export diversification in oil producing countries evidence from oil booms abstract this paper examines the factors behind export diversification in oil countries specifically we investigate the impact of oil booms on export diversification through an empirical framework the paper finds that economy s export structure before the oil boom determines whether oil windfalls might affect the diversification process thus an oil boom negatively affects export diversification only if countries initially exhibit low levels of diversification in countries with a high level of diversification before the boom an oil boom has no impact on diversification these results are based on a large sample of 134 countries and are robust to various sensitivity analyses they are corroborated with data from the manufacturing sector which show that oil booms only reduce diversification in countries with a small manufacturing sector prior to the boom

cross country evidence on the link between volatility and growth this paper presents empirical evidence against the standard dichotomy in macroeconomics that separates growth from the volatility of economic fluctuations in a sample of ninety two countries as well as a sample of oecd countries the authors find that countries with higher volatility have lower growth the addition of standard control variables strengthens the negative relationship the authors also find that government spending induced volatility is negatively associated with growth even after controlling for both time and country fixed effects copyright 1995 by american economic association
