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

democracy and macroeconomic performance in underdeveloped countries an empirical analysis in this study the author examines how inflation and economic growth differ in more and less democratic regimes and in new and mature democracies the analysis is based on a panel research design featuring annual data from a large sample of underdeveloped countries and two way fixed effects regression analysis the author s central finding is that more democratic countries have higher inflation and slower growth than less democratic countries inflation apparently is higher than more democratic countries mainly because they have higher fiscal deficits and faster wage growth this higher inflation marginally reduces economic growth in these countries the author also finds that new and mature democracies do not have significantly different inflation and growth rates the findings suggest that unrestrained political participation and the resulting demands placed on state officials undermine democratic performance

the long term consequences of resource based specialisation using geological variation in oil abundance in the southern us i examine the long term effects of resource based specialisation through economic channels in 1890 oil abundant counties were similar to other nearby counties but after oil was discovered they began to specialise in its production from 1940 90 oil abundance increased local employment per square kilometre especially in mining but also in manufacturing oil abundant counties had higher population growth higher per capita income and better infrastructure 2010 the author s the economic journal 2010 royal economic society

a multi objective multi period stochastic programming model for public debt management while raising debt on behalf of the government public debt managers need to consider several possibly conflicting objectives and have to find an appropriate combination for government debt taking into account the uncertainty with regard to the future state of the economy in this paper we explicitly consider the underlying uncertainties with a complex multi period stochastic programming model that captures the trade offs between the objectives the model is designed to aid the decision makers in formulating the debt issuance strategy we apply an interactive procedure that guides the issuer to identify good strategies and demonstrate this approach for the public debt management problem of turkey

scenario modelling for selective hedging strategies abstract we study currency risk management in the context of scenario analysis we develop scenario based optimization models that jointly determine the portfolio composition and the hedging strategy within each currency thus the model prescribes optimal selective hedging policies we then study empirically the performance of the models the new elements of our empirical analysis are various horizons one month and one semester various currency bases explicit incorporation of realistic transaction costs the results show that selective hedging strategies dominate the alternatives under some conditions and that transaction costs are very important in determining the profitability of various currency risk management strategies for both stocks and bonds at the one month horizon

a dynamic stochastic programming model for international portfolio management we develop a multi stage stochastic programming model for international portfolio management in a dynamic setting we model uncertainty in asset prices and exchange rates in terms of scenario trees that reflect the empirical distributions implied by market data the model takes a holistic view of the problem it considers portfolio rebalancing decisions over multiple periods in accordance with the contingencies of the scenario tree the solution jointly determines capital allocations to international markets the selection of assets within each market and appropriate currency hedging levels we investigate the performance of alternative hedging strategies through extensive numerical tests with real market data we show that appropriate selection of currency forward contracts materially reduces risk in international portfolios we further find that multi stage models consistently outperform single stage models our results demonstrate that the stochastic programming framework provides a flexible and effective decision support tool for international portfolio management

do workers remittances reduce the probability of current account reversals the authors combine the literature on financial crises in emerging markets and developing economies with that on international migrations by investigating whether the increasingly large flows of workers remittances can help reduce the probability of current account reversals the rationale for this stands in the great stability and low cyclicality of remittances as compared with other private capital flows these properties combined with the fact that remittances are cheap inflows of foreign currencies might reduce the probability that foreign investors suddenly flee out of emerging markets and developing economies and trigger a dramatic current account adjustment the authors find that remittances can have such a beneficial effect in particular they show that a high level of remittances as a ratio of gdp makes the relationship between a decreasing stock of international reserves over gdp and a higher probability of current account crises less stringent the same occurs though less neatly for the positive relationship between an increasing stock of external debt over gdp and the probability of current account reversals the results point also to a threshold effect of remittances the mechanisms just described are in fact much stronger when remittances are above 3 percent of gdp

fiscal deficits and inflation abstract macroeconomic theory postulates that persistent fiscal deficits are inflationary yet empirical research has had limited success in uncovering this relationship this paper reexamines the issue in light of broader data and a new modeling approach that incorporates two key features of the theory unlike previous studies we model inflation as non linearly related to fiscal deficits through the inflation tax base and estimate this relationship as intrinsically dynamic using panel techniques that explicitly distinguish between short and long run effects of fiscal deficits results spanning 107 countries over 1960 2001 show a strong positive association between deficits and inflation among high inflation and developing country groups but not among low inflation advanced economies

remittances inflation and exchange rate regimes in small open economies remittances are private monetary transfers yet the rapidly growing literature on the subject often ignores the role that exchange rate regimes play in determining the effect remittances have on a recipient economy this paper uses a theoretical model and panel vector autoregression techniques to explore the role exchange rate regimes play in understanding the effect of remittances the analysis considers yearly and quarterly data for seven latin american countries our theoretical model predicts that remittances should temporarily increase inflation and generate an increase in the domestic money supply under a fixed regime but temporarily decrease inflation and generate no change in the money supply under a flexible regime these differences are borne out in the data this adds to our understanding of the true effect of remittances on economies and suggests that other results in the literature that do not control for regimes may be biased

do giant oilfield discoveries fuel internal armed conflicts we use new data to examine the effects of giant oilfield discoveries around the world since 1946 on average these discoveries increase per capita oil production and oil exports by up to 50 percent but these giant oilfield discoveries also have a dark side they increase the incidence of internal armed conflict by about 5 8 percentage points this increased incidence of conflict due to giant oilfield discoveries is especially high for countries that had already experienced armed conflicts or coups in the decade prior to discovery

an empirical analysis of a regional dutch disease the case of canada while there has been extensive research on the dutch disease dd very little attention if any has been devoted to the regional mechanisms through which it may manifest itself this is the first empirical attempt to research a regional dd by looking at the local and spatial impacts of resource windfalls across canadian provinces and territories we construct a new panel dataset to examine separately the key dd channels namely the spending effect and the resource movement effect our analysis reveals that the standard dd mechanisms are also relevant at the regional level specifically we find that a resource windfalls are associated with higher inflation and a labour capital shift from to non primary tradable sectors b resource windfalls in neighbouring regions are associated with a capital labour shift from to non primary tradable sectors in the source region c the spatial dd explains 51 20 of the adverse effects of resource windfalls in neighbouring regions on region specific non mineral international exports in the source region and does not significantly affect domestic ones

remittances monetary policy and partial sterilization author affiliation diego e vacaflores dv13 txstate edu acknowledgment the author thanks dennis w jansen for his insightful contributions and continuous guidance i also thank the editor kent kimbrough and two anonymous referees for their valuable comments and suggestions 1 introductionremittances have increased over the last several decades international estimates of official remittance flows suggest that the total amount of worker remittances have increased to us 300 billion in 2010 inter american development bank 2012 this increase may in part be attributed to the rapid growth of money transfer institutions which has reduced the average transaction cost and has made them more visible however it may also be indicative of an actual increase in these monetary transfers due to increased migration flows which now represent approximately 45 of net private capital flows to developing countries the importance of remittances for remittances receiving developing countries does not just come from their size but mainly from its potential and actual effects on both the society and the individual remittances affect labor market decisions school retention export sector competitiveness and financial deepening funkhouser 1992 glytsos 2002 cox edwards and ureta 2003 amuedo dorantes and pozo 2004 chami fullenkamp and jahjah 2005 giuliano and ruiz arranz 2009 in terms of consumption remittance flows have gone from satisfying basic needs to providing a vast array of durable goods for recipient households they can thus potentially promote economic growth and development through higher domestic demand if motivated by altruism or through enhanced productive capacity if motivated by self interest most of the literature on remittances focuses on the microeconomic implication of such flows for the sender and for the receiver of these funds on the basis of survey data this trend in the literature has examined the motivations to remit such as contractual arrangements altruism repayment of migration costs and so on and the uses of these funds in the home country e g for education health care entrepreneurial initiatives social works etc at the macro level the literature on the impact of remittances on the recipient country is sparse but growing as researchers realize that it could have important effects on the overall economy however economists have overlooked the examination of the potential influence that higher levels of remittances can have on the implementation of monetary policy and thus its understanding is still limited since remittances provide a secondary income to households they would affect decisions with respect to labor supply and consumption which can alter the effectiveness of monetary policy when this additional income is a significant portion of a household s income additionally although domestic governments usually try to sterilize capital flows to sustain a given policy the high levels of informality in some developing countries and the significant portion of remittances that continue to flow through informal channels make monetary targeting problematic given these potential complications monetary policy could potentially have a differential impact depending on the remittances share of gdp and fluctuations in remittances can affect the amount of money in circulation and therefore economic performance accounting for such influences thus became imperative for stabilization policy this study examines the potentially different impact that monetary policy can have on output depending on the relative share of remittances as a percentage of gdp and the differential effect that remittances shocks can have on the main macroeconomic aggregates when economies do not fully sterilize such inflows channels never explored before it builds on the theoretical model developed by jansen vacaflores and naufal 2010 explicitly incorporating remittances in a small open economy framework and is able to show that monetary policy has a differential effect on output depending on the relative size of these remittances

the curse of natural resources in fractionalized countries abstract this paper develops a model that can explain why natural resources are a blessing for some countries but a curse for others in this model natural resources cause fighting activities between rivalling groups fighting reduces productive activities and weakens property rights making productive activities even less attractive the aggregate production decrease exceeds the natural resources direct positive income effect if and only if the number of rivalling groups is sufficiently large the model thus predicts that natural resources lower incomes in fractionalized countries but increase incomes in homogenous countries empirical evidence supporting this prediction is provided

comment on generating scenario trees for multistage decision problems in models of decision making under uncertainty one typically has to approximate the uncertainties by a limited number of discrete outcomes ha yland and wallace 2001 formulate a nonlinear programming problem to generate sucha limited number of discrete outcomes while satisfying specified statistical properties they have developed and employed this method for a stochastic multistage asset allocation problem when the method is applied to such financial optimization problems under uncertainty we argue here that it does not suffice to match statistical properties to obtain realistic outcomes the limited description of the uncertainty in such models should also exclude arbitrage opportunities and thereby be consistent with financial asset pricing theory we illustrate that the method proposed by ha yland and wallace can result in arbitrage opportunities in the scenario tree if only statistical properties are imposed we show how one can check ex post for the presence of arbitrage opportunities in a scenario tree by checking for the existence of solutions to sets of linear equations arbitrage opportunities can also be precluded ex ante in the scenario tree by adding constraints to the nonlinear programming problem of ha yland and wallace

do remittances induce inflation fresh evidence from developing countries the goal of this article is to examine the determinants of inflation in both the short run and the long run for 54 developing countries using a panel data set covering the 1995 2004 period apart from the commonly used economic determinants of inflation we model the impact of remittances and institutional variables on inflation using the arellano and bond panel dynamic estimator and the arellano and bover and the blundell and bond system generalized method of moments estimator we find evidence that in developing countries remittances generate inflation the effect of remittances on inflation is more pronounced in the long run moreover we find that openness debt current account deficits the agricultural sector and the short term u s interest rate have a positive effect on inflation we also find that improvements in democracy reduce inflation

multilateral resistance to migration the rate of migration observed between two countries does not depend solely on their relative attractiveness but also on the one of alternative destinations following the trade literature we term the influence exerted by other destinations on bilateral flows as multilateral resistance to migration and we show how it can be accounted for when estimating the determinants of migration rates in the context of a general individual random utility maximization model we propose the use of the common correlated effects estimator pesaran 2006 and apply it to high frequency data on the spanish immigration boom between 1997 and 2009 compared to more restrictive estimation strategies developed in the literature the bias goes in the expected direction we find a smaller effect of gdp per capita and a larger effect of migration policies on bilateral rates

aid volatility and real business cycles in a developing open economy this article analyzes the impact of the unpredictability of foreign aid on macroeconomic fluctuations in the recipient country i build a small open economy business cycle model that accounts for foreign aid shocks with no preference shocks the model is calibrated to reflect the structural empirical regularities of cote d ivoire a typical aid dependent developing country the parameters of the exogenous shocks are estimated using bayesian methods and time series data for cote d ivoire the model produces business cycle patterns that are consistent with the data and key stylized facts specifically the excess volatility of consumption with respect to output is successfully replicated the results suggest that the unpredictability of foreign aid contributes to explain the volatility of business cycles in the recipient economy and has negative welfare effects

oil rents corruption and state stability evidence from panel data regressions abstract we examine the effects of oil rents on corruption and state stability exploiting the exogenous within country variation of a new measure of oil rents for a panel of 30 oil exporting countries during the period 1992 2005 we find that an increase in oil rents significantly increases corruption significantly deteriorates political rights while at the same time leading to a significant improvement in civil liberties we argue that these findings can be explained by the political elite having an incentive to extend civil liberties but reduce political rights in the presence of oil windfalls to evade redistribution and conflict we support our argument documenting that there is a significant effect of oil rents on corruption in countries with a high share of state participation in oil production while no such link exists in countries where state participation in oil production is low

natural resource access and local economic growth abstract we explore the existence of a local resource curse related to brazil s oil using oil price annual changes interacted with measures of local proximity to oil reserves we find that oil royalty receiving locations in brazil that are closer to an oil field are characterized by a higher level of income per capita when controlling for a range of potentially confounding factors furthermore in a panel setting we find that better geographical access to oil fields generates a greater positive effect of oil prices on local income per capita moreover this positive impact of oilfield proximity on the effect of oil prices is enhanced in oil rich states importantly these effects appear to be independent of the amount of oil royalties suggesting the role of an indirect linkage effect

exchange rate pass through to domestic prices does the inflationary environment matter abstract the paper tests a hypothesis suggested by j taylor 2000 low inflation pass through and the pricing power of firms european economic review 44 7 1389 1408 that a low inflationary environment leads to a low exchange rate pass through to domestic prices to test this hypothesis the paper derives a pass through relation based on new open economy macroeconomic models a large database that includes 1979 2000 data for 71 countries is used to estimate this relation there is strong evidence of a positive and significant association between the pass through and the average inflation rate across countries and periods the inflation rate moreover dominates other macroeconomic variables in explaining cross regime differences in the pass through

workers remittances and the real exchange rate a paradox of gifts abstract we test the impact of workers remittances on the real exchange rate using a panel of 13 latin american and caribbean countries the analysis reveals that workers remittances have the potential to inflict economic costs on the export sector of receiving countries by reducing its international competitiveness our findings raise concerns parallel to those raised by dutch disease or resource boom models where resource discoveries result in real exchange rate appreciation and shifting of resources from the traded to the nontraded sectors of the economy

is complete hedging optimal for international bond portfolios over the 1980s however non u s investors could have lowered their international portfolios risks by taking on some currency exposure for these investors the benefits of diversification across currencies more than offset the cost of the currencies volatilities evidently the free lunch argument misses something and investors should be concerned that the missing link might change across countries or over time

effects of higher order moments on the newsvendor problem abstract in this paper we propose a stochastic programming model for the well known single period newsvendor problem by adopting the conditional value at risk cvar as the risk metric in the objective function the demand uncertainty is modeled in terms of discrete scenarios that reflect the empirical distributions implied by market demand data our numerical results demonstrate that the higher order moments skewness and kurtosis of demand have obvious effects on the newsvendor problem and the stochastic programming framework provides a flexible and effective decision support tool for the newsvendor problem

cvar models with selective hedging for international asset allocation abstract we develop an integrated simulation and optimization framework for multicurrency asset allocation problems the simulation applies principal component analysis to generate scenarios depicting the discrete joint distributions of uncertain asset returns and exchange rates we then develop and implement models that optimize the conditional value at risk cvar metric the scenario based optimization models encompass alternative hedging strategies including selective hedging that incorporates currency hedging decisions within the portfolio selection problem thus the selective hedging model determines jointly the portfolio composition and the level of currency hedging for each market via forward exchanges we examine empirically the benefits of international diversification and the impact of hedging policies on risk return profiles of portfolios we assess the effectiveness of the scenario generation procedure and the stability of the model s results by means of out of sample simulations we also compare the performance of the cvar model against that of a model that employs the mean absolute deviation mad risk measure we investigate empirically the ex post performance of the models on international portfolios of stock and bond indices using historical market data selective hedging proves to be the superior hedging strategy that improves the risk return profile of portfolios regardless of the risk measurement metric although in static tests the mad and cvar models often select portfolios that trace practically indistinguishable ex ante risk return efficient frontiers in successive applications over several consecutive time periods the cvar model attains superior ex post results in terms of both higher returns and lower volatility

determinants of workers remittances an empirical investigation for a panel of eleven developing asian economies we explore the key motives of migrant workers remittances from abroad for 11 major asian migrant sending countries using panel regressions we find that relative higher growth rate interest rate and capital market returns of home over the host investment financial deepening at home have significant impact on remittance inflows into asia along with higher per capita incomes and international crude oil prices with incorporation of per capita incomes and lagged impact of remittances we observe an emergence of consumption motives to remit therefore we conclude that both investment and altruistic motives are the driving forces for remittances inflows into the asian economies

seigniorage and political instability the importance of seigniorage relative to other sources of government revenue differs markedly across countries this paper tries to explain this regularity by studying a political model of tax reform the model implies that countries with a more unstable and polarized political system will have more inefficient tax structures and thus will rely more heavily on seigniorage this prediction of the model is tested on cross sectional data for seventy countries the authors find that after controlling for other variables political instability is positively associated with seigniorage copyright 1992 by american economic association

currency crashes in emerging markets an empirical treatment we use a panel of annual data for over 100 developing countries from 1971 through 1992 to characterize currency crashes we define a currency crash as a large change of the nominal exchange rate that is also a substantial increase in the rate of change of nominal depreciation we examine the composition of the debt as well as its level and a variety of other macroeconomic factors external and foreign crashes tend to occur when output growth is low the growth of domestic credit is high and the level of foreign interest rates are high a low ratio of fdi to debt is consistently associated with a high likelihood of a crash

the economic impact of the coal boom and bust in this paper we examine the impact of the coal boom in the 1970s and the subsequent coal bust in the 1980s on local labour markets in kentucky ohio pennsylvania and west virginia we address two main questions in our analysis how were non mining sectors affected by the shocks to the mining sector how did these effects differ between sectors producing local goods and those producing traded goods we find evidence of modest employment spillovers into sectors with locally traded goods but not into sectors with nationally traded goods

migration networks and microenterprises in mexico are migration networks associated with lower capital costs or the alleviation of capital constraints we examine these questions with data measuring access to remittance flows among small scale entrepreneurs in mexico using a survey of more than 6000 self employed workers and small firm owners located in 44 urban areas of mexico we estimate the impact of attachment to migration networks on the level of capital investment the capital output ratio sales and profits of microenterprises the impact is identified from the geographic pattern of migration from mexico driven by the completion of rail lines in the early 1900s for the full sample of firms we find that migration is associated with higher investment levels and higher profits but not higher sales the strongest effects on investment are in the categories of automobiles tools and inventories when the sample is limited to firms in high capital sectors investment sales and profits all increase with attachment to the migration networks suggesting that attachment to the migration network alleviates capital constraints in those sectors

do international migration and remittances reduce poverty in developing countries summary few studies have examined the impact of international migration and remittances on poverty in the developing world this paper fills this lacuna by constructing and analyzing a new data set on international migration remittances inequality and poverty from 71 developing countries the results show that both international migration and remittances significantly reduce the level depth and severity of poverty in the developing world after instrumenting for the possible endogeneity of international migration and controlling for various factors results suggest that on average a 10 increase in the share of international migrants in a country s population will lead to a 2 1 decline in the share of people living on less than 1 00 per person per day after instrumenting for the possible endogeneity of international remittances a similar 10 increase in per capita official international remittances will lead to a 3 5 decline in the share of people living in poverty

remittances and financial access is there really a link and for whom evidence from mexican household data in policy discussions it has frequently been claimed that migrants remittances could function as a catalyst for financial access among receiving households this paper provides empirical evidence on this hypothesis from mexico a major receiver of remittances worldwide using the mexican family life survey panel mxfls for 2002 and 2005 the results from the fixed effects logit model show that receiving remittances is strongly correlated with the ownership of savings accounts and to a limited degree with the availability of borrowing options effects are particularly important for microfinance institutions and more important for rural households compared to urban households

does oil corrupt evidence from a natural experiment in west africa abstract this paper explores the oil discovery announcements in sao tome and principe 1997 1999 to assess the role of natural resources in determining corruption for this purpose we use a natural experiment framework which contrasts sao tome and principe to cape verde a control west african country sharing the same colonial past and important recent economic and political shocks our measurement is based on tailored household surveys we conducted in both island countries the unique survey instrument was retrospective and used personal histories to elicit memories from the respondents we analyze changes in perceived corruption across a wide range of public services and allocations we find clearest increases on vote buying education namely in the allocation of scholarships and customs ranging from 31 to 40 of the subjective scale we interpret these findings as symptoms of increased competition for core state resources

exchange rate uncertainty forward contracts and international portfolio selection in this paper ex ante efficient portfolio selection strategies are developed to realize potential gains from international diversification under flexible exchange rates it is shown that exchange rate uncertainty is a largely nondiversiflable factor adversely affecting the performance of international portfolios therefore it is essential to effectively control exchange rate volatility for that purpose two methods of exchange risk reduction are simultaneously employed multicurrency diversification and hedging via forward exchange contracts the empirical findings show that international portfolio selection strategies designed to control both estimation and exchange risks almost consistently outperform the u s domestic portfolio in out of sample periods since grubel 11 applied modern portfolio theory mpt to international investment various authors such as levy and sarnat 17 solnik 20 and lessard 16 have examined the gains from international diversification of investment portfolios for the purpose of establishing the gains from international diversification these studies constructed international portfolios using historical risk and return data from a period of fixed or relatively stable exchange rates and showed that internationally diversified portfolios dominated purely domestic portfolios in terms of mean variance efficiency from the standpoint of today s investors however the previous studies fail to offer operational guidance for international diversification for two important reasons first it is now questionable whether the past findings are still relevant under the current flexible exchange rate regime second by being ex post in nature the past studies ignored the issue of estimation risk or parameter uncertainty and therefore may have overstated the realizable portion of the potential gains from international diversification fluctuating exchange rates are likely to mitigate the potential gains from international diversification by making investment in foreign securities more risky as will be shown later a fluctuating exchange rate contributes to the risk of foreign investment not only through its own variance but also through its positive covariances with the local stock market returns during our sample period of 1980 through 1985 for example exchange rate volatility is found to account for about fifty percent of the volatility of dollar returns from investment in the stock markets of such major countries as germany japan and the u k furthermore the exchange rate changes vis a vis the u s dollar are found to be

the optimal migration duration and activity choice after re migration if migrants return to their origin countries two questions arise which are of immediate economic interest for both immigration and emigration country what determines their optimal migration duration and what are the activities migrants choose after a return little research has been devoted to these two issues this paper utilises a unique survey data set which records activities of returned migrants we first illustrate the activities of immigrants after returning we show that more than half of the returning migrants are economically active after return and most of them engage in entrepreneurial activities we then develop a model where migrants decide simultaneously about the optimal migration duration and their after return activities guided by this model we specify and estimate an empirical model where the after return activity and the optimal migration duration are simultaneously chosen

the local impact of mining on poverty and inequality evidence from the commodity boom in peru summary this paper studies the impact of mining activity on socioeconomic outcomes in local communities in peru in the 1990s and 2000s the value of peruvian mining exports grew by 15 times and since the early 2000s one half of fiscal revenues from mining have been devolved to local governments has this boom benefitted people in local communities using the district level poverty map of 2007 the latest available with accurate data on consumption poverty and inequality together with district level data on mining production and fiscal transfers to local governments we present some evidence to answer this question we find that mining districts have larger average consumption per capita and lower poverty rates than otherwise similar districts these positive impacts however decrease drastically with administrative and geographic distance from mining centers moreover consumption inequality within mining districts is higher than in comparable nonproducing districts this dual effect of mining is accounted for by first the better educated immigrants required and attracted by mining activity and second the jobs that some community natives obtain in industries and services related to mining the inequalizing impact of mining both across and within districts may help explain the social discontent with mining in peru despite its enormous revenues an area for future research highlighted in the paper regards the usefulness of fiscal transfers to local governments the mining canon a key component of the fiscal decentralization reform of 2002 we find neither a detrimental nor a beneficial effect from the mining canon in peru whether this is explained by our early measurement of results 5 years into the decentralization program or by the lack of implementation capacity of local governments remains to be answered

international migration remittances and household investment evidence from philippine migrants exchange rate shocks how do households respond to overseas members economic shocks overseas filipinos in dozens of countries experienced sudden heterogeneous changes in exchange rates during the 1997 asian financial crisis appreciation of a migrant s currency against the philippine peso leads to increases in household remittances from overseas the estimated elasticity of philippine peso remittances with respect to the exchange rate is 0 60 positive migrant shocks lead to enhanced human capital accumulation and entrepreneurship in origin households child schooling and educational expenditure rise while child labour falls households also work more hours in self employment and become more likely to start relatively capital intensive household enterprises

does openness to trade make countries more vulnerable to sudden stops or less using gravity to establish causality openness to trade is one factor that has been identified as determining whether a country is prone to sudden stops in capital inflows several authors have offered empirical evidence that having a large tradable sector reduces the contraction necessary to adjust to a given cut off in funding such studies may however be subject to the problem that trade is endogenous we use the gravity instrument for trade openness which is constructed from geographical determinants of bilateral trade we find that openness indeed makes countries less vulnerable to crises and that the relationship is even stronger when correcting for the endogeneity of trade

the rise of risk based pricing of mortgage interest rates in italy abstract this paper assesses how much mortgage interest rates in italy are priced on credit risk as proxied by the probability of household mortgage delinquency estimated using the eu silc database owing to data availability we restrict the analysis of mortgage pricing to italian households consistent with the more widespread use of credit scoring estimates indicate that italian lenders have increasingly priced mortgage interest rates on household credit risk for mortgages granted between 2000 and 2007 we find that a 1 point increase in the probability of default is associated with a 21 basis point rise in mortgage interest rates lower than the 38 basis point premium edelberg 2006 estimated for the us at the end of the 1990s

resource abundance and economic growth in the united states abstract it is a common assumption that regions within the same country converge to approximately the same steady state income levels the so called absolute convergence hypothesis focuses on initial income levels to account for the variability in income growth among regions empirical data seem to support the absolute convergence hypothesis for us states but the data also show that natural resource abundance is a significant negative determinant of growth we find that natural resource abundance decreases investment schooling openness and r d expenditure and increases corruption and we show that these effects can fully explain the negative effect of natural resource abundance on growth

currency hedging for international portfolios this paper examines the benefits from currency hedging both for speculative and risk minimization motives in international bond and equity portfolios the riskreturn performances of globally diversified portfolios are compared with and without forward contracts over the period 1974 to 1990 inclusion of forward contracts results in statistically significant improvements in the performance of unconditional portfolios containing bonds conditional strategies are also implemented both in sample and out of sample and are shown to both significantly improve the risk return tradeoff of global portfolios and to outperform unconditional hedging strategies whether international portfolios should be hedged against currency risks is the subject of an active debate the theoretical side of the debate has been closely associated with two strands in the academic literature international asset pricing and optimal hedging in the futures markets in the international asset pricing model iapm of solnik 1974 optimal portfolios contain positions in forward contracts or equivalently foreign currency denominated bills these positions which can differ from the positions in foreign stocks have since been termed hedges black 1990 shows that under additional assumptions the hedge ratios should be identical for all investors regardless of their nationality universality and that investors should never fully hedge their foreign currency exposures similarly theoretical models from the futures literature produce demands for hedging instruments that contain both speculative and hedging components the empirical issue unanswered so far is whether adding forward contracts to international portfolios significantly improves the risk return profile of global investments empirical research has barely begun to respond to the challenges of theoretical models there exists little empirical evidence on either the relevance of black s universal hedge ratios or the optimality of hedge ratios less than one instead researchers have concentrated on the benefits of fully hedging exchange risk for example eun and resnick 1988 indicate that stock portfolios perform better when fully hedged but offer no statistical tests

international migration remittances and schooling evidence from el salvador abstract we examine the effect of remittances from abroad on households schooling decisions using data for el salvador following the massive war related emigration of the 1980s remittances became a significant source of household income throughout the 1990s we use the cox proportional hazard model to examine the determinants of school attendance measuring income from a source that is uncorrelated with parental schooling remittances we find that remittances have a large significant effect on school retention we estimate that while household income net of remittances has a small though significant impact on the hazard of leaving school in rural and urban areas remittances have a much larger impact on the hazard of leaving school in urban areas the effect of remittances is at its smallest 10 times the size of the effect of other income in rural areas the effect of remittances is about 2 6 times that of other income our finding is of interest in that it suggests that subsidizing school attendance particularly in poor areas may have a large impact on school attendance and retention even if parents have low levels of schooling

remittances and portfolio values an inquiry using immigrants from africa europe and the americas summary using a recent spanish database we show that remittances respond to cross country differences in portfolio values behavior consistent with immigrant s access to trans national networks responsiveness to portfolio variables is found to persist regardless of education level there are however differences in the portfolio variables to which immigrants respond as we would expect given migrants diverse backgrounds region of origin and motive for emigrating remitting patterns are found to change with the length of migration spells suggestive that remittances sent for portfolio motives become more likely as the immediate needs of home family are addressed and asset accumulation becomes more important

migration remittances and male and female employment patterns little is known about the labor market impacts of workers remittances despite their magnitude in countries with considerable outmigration reports that families receiving international remittances severely curtail their work efforts are fairly common in the popular press e g robert frank 2001 yet we lack rigorous analyses of how male and female labor supplies respond to increases in remittance income to either support or refute these anecdotal observations according to the neoclassical model of labor leisure choice mark r killingsworth 1983 remittances a source of nonlabor income may lift budget constraints raise reservation wages and through an income effect reduce the employment likelihood and hours worked by remittance receiving individuals the receipt of remittances is usually preceded by the out migration of working aged household members however which may induce changes in the labor supply of nonmigrating household members in order to compensate for forgone income or to defray migration related expenses distinguishing the disruptive effect from the income effect of remittance inflows is problematic as most surveys do not contain detailed information on household outmigration and remittance receipt to the extent that these two effects are expected to have opposite impacts on labor supply however we can assess which effect dominates the impact of remittances on the decision to work has been previously examined by edgard rodriguez and erwin r tiongson 2001 in manila and by edward funkhouser 1992 in managua without accounting for the endogeneity of remittances with respect to labor supply they conclude that remittances reduce employment funkhouser also finds that remittances slightly increase self employment while informative these studies focus on the decision to work and do not consider that without altering employment rates remittances may change the hours worked and or the type of work performed in the receiving economy furthermore the impact may be different on male and female labor supplies and responsiveness to remittance income may vary from rural to urban areas using data from mexico a country with a large and growing remittance inflow we address the following questions how does the employment status and hours worked by men and women vary owing to international remittances do male and female labor supplies differ across various types of employment in rural versus urban areas due to higher remittance inflows

remittances and economic growth a meta analysis abstract expatriate workers remittances represent an important source of financing for low and middle income countries no consensus however has yet emerged regarding the effect of remittances on economic growth in a quantitative survey of 538 estimates reported in 95 studies we find that approximately 40 of the studies report a positive effect 40 report no effect and 20 report a negative effect our results indicate publication bias in favor of positive effects correcting for the bias using recently developed techniques we find that the mean effect of remittances on growth is still positive but economically small nevertheless our results uncover noticeable regional differences remittances are growth enhancing in asia but not in africa studies that do not control for alternative sources of external finance such as foreign aid and foreign direct investment mismeasure the effect of remittances finally time series studies and studies ignoring endogeneity issues report systematically larger effects of remittances on growth

do remittances lead to a public moral hazard in developing countries an empirical investigation abstract this article tests the hypothesis that in a context of bad governance remittance inflows strongly reduce public spending on education and health in receiving countries a phenomenon called the public moral hazard problem using a large sample of 86 developing countries over the period 1996 2007 and after factoring in the endogeneity of remittances the results suggest a negative impact of remittances on public spending on education and health when governance is bad in remittance dependent economies

sharp reductions in current account deficits an empirical analysis abstract we study determinants and consequences of sharp reductions in current account imbalances reversals in low and middle income countries we pose two questions what triggers reversals and what factors explain how costly reversals are we find that both domestic variables such as the current account balance openness and the level of reserves and external variables such as terms of trade shocks us real interest rates and growth in industrial countries seem to play an important role in explaining reversals in current account imbalances we also find some evidence that countries with a less appreciated real exchange rate higher investment and more openness prior to the reversal tend to grow faster after a reversal occurs

international portfolio management with affine policies abstract while dynamic decision making has traditionally been represented as scenario trees these may become severely intractable and difficult to compute with an increasing number of time periods we present an alternative tractable approach to multiperiod international portfolio optimization based on an affine dependence between the decision variables and the past returns because local asset and currency returns are modeled separately the original model is non linear and non convex with the aid of robust optimization techniques however we develop a tractable semidefinite programming formulation of our model where the uncertain returns are contained in an ellipsoidal uncertainty set we add to our formulation the minimization of the worst case value at risk and show the close relationship with robust optimization numerical results demonstrate the potential gains from considering a dynamic multiperiod setting relative to a single stage approach

remittance outflows and inflation the case of the gcc countries abstract we examine the effect of remittance outflows on inflation in the remitting countries the growth of remittance outflows depresses inflation rate

more oil less democracy evidence from worldwide crude oil discoveries this article exploits variations in the timing and size of oil discoveries to identify the impact of oil wealth on democracy i find that discovering 100 billion barrels of oil approximately the initial endowment of iraq pushes a country s democracy level almost 20 percentage points below trend after three decades the estimated effect is larger for oilfields with higher quality oil and lower exploration and extraction costs however the estimates become less precise when oil abundance is measured by oil discovery per capita suggesting politicians may care about the level instead of the per capita value of oil wealth

remittances and economic growth larger impacts in smaller countries this paper examines the impact of remittances on economic growth in small island developing states sids results from variants of an empirical model suggest that while on average there is at best no association between remittances and growth in developing countries there is a positive association between these variables in sids this finding holds for sids in sub saharan africa and the pacific but not for those in latin america and the caribbean relationships between remittances economic volatility and household labour supply are offered as reasons for these findings

globalization domestic politics and social spending in latin america a time series cross section analysis 1973 97 this study examines the effects of globalization democratization and partisanship on social spending in fourteen latin american countries from 1973 to 1997 using a pooled time series error correction model the authors examine three sets of issues first following debates in the literature on oecd countries they want to know whether social spending has been encouraged or constrained by integration into global markets within this context they examine the extent to which such outcomes might be influenced by two additional sets of domestic political and institutional factors discussed in work on developed countries the electoral pressures of democratic institutions and whether or not popularly based governments are in power the authors show that trade integration has a consistently negative effect on aggregate social spending and that this is compounded by openness to capital markets this is the strongest and most robust finding in the study neither democratic nor popularly based governments consistently affect overall social spending the authors then disaggregate spending into social security transfers and expenditures on health and education they find that popularly based governments tend to protect social security transfers which tend to flow disproportionately to their unionized constituencies but they have a negative impact on health and education spending conversely a shift to democracy leads to increases in health and education spending which reaches a larger segment of the population the authors conclude by emphasizing the contrasting political logics of the different types of social spending

the political resource curse this paper studies the effect of additional government revenues on political corruption and on the quality of politicians both with theory and data the theory is based on a political agency model with career concerns and endogenous entry of candidates the data refer to brazil where federal transfers to municipal governments change exogenously at given population thresholds allowing us to implement a regression discontinuity design the empirical evidence shows that larger transfers increase observed corruption and reduce the average education of candidates for mayor these and other more specific empirical results are in line with the predictions of the theory jel d72 d73 h77 o17 o18

inflation in open economies abstract this paper relates the time consistent inflation rate to the degree of trade openness of an economy the mechanism linking the welfare effects of monetary surprises and hence the incentives to inflate to openness does not rely on a large country terms of trade effect but rather is due to imperfect competition and nominal price rigidity in the non traded sector the empirical evidence supports the main predictions of the model 1997 elsevier science b v

universal hedging optimizing currency risk and reward in international equity portfolios investors can increase their returns by holding foreign stocks in addition to domestic ones they can also gain by taking the appropriate amount of exchange risk but what amount is appropriate assume that investors see the world in light of their own consumption goods and count both risk and expected return when figuring their optimum hedges assume that they share common views on stocks and currencies and that markets are liquid and there are no barriers to international investing in this perfect world it is possible to derive a formula for the optimal hedge ratio this formula requires three basic inputs the average across countries of the expected returns on the world market portfolio the average across countries of the volatility of the world market portfolio and the average across all pairs of countries of exchange rate volatility these values can be estimated from historical data the formula in turn gives the circumstances for three rules 1 hedge foreign equity 2 hedge less than 100

trade openness and inflation episodes in the oecd boschen and weise journal of money credit and banking 2003 model the probability of a large upturn in inflation in the oecd an inflation start we extend their work to consider the impact of trade openness on the probability of such an event the main finding is that increased openness reduces the probability of an inflation start both directly and indirectly through restricting the role of general elections in triggering inflation starts

financial openness sudden stops and current account reversals in this paper i use a panel data set to investigate the mechanics of sudden stops of capital inflows and current account reversals i am particularly interested in four questions a what is the relationship between sudden stops and current account reversals b to what extent does financial openness affect the probability of a country being subject to a current account reversal in other words do restrictions on capital mobility reduce the probability of such occurrences c does openness both trade openness and financial openness play a role in determining the effect of current account reversals on economic performance i e gdp growth and d does the exchange rate regime affect the intensity with which reversals affect real activity the empirical analysis shows that sudden stops and current account reversals have been closely related the econometric analysis suggests that restricting capital mobility does not reduce the probability of experiencing a reversal current account reversals in turn have had a negative effect on real growth that goes beyond their direct effect on investment the regression analysis indicates that the negative effects of current account reversals on growth will depend on the country s degree of trade openness more open countries will suffer less in terms of lower growth relative to trend than countries with a lower degree of trade openness on the other hand the degree of financial openness does not appear to be related to the intensity with which reversals affect real economic performance the empirical analysis also suggests that countries with more flexible exchange rate regimes are able to accommodate better shocks stemming from a reversal than countries with more rigid exchange rate regimes this abstract was borrowed from another version of this item

on valuing and hedging european options when volatility is estimated directly abstract we quantify the effects on contingent claim valuation of using an estimator for the unknown volatility of a geometric brownian motion gbm process the theme of the paper is to show what difficulties can arise when failing to account for estimation risk our narrative uses a direct estimator of volatility based on the sample standard deviation of increments of the underlying brownian motion after replacing the direct estimator into the gbm we derive the resulting distribution function of the approximated gbm for any time point this allows us to present post estimation distributions and valuation formulae for an assortment of european contingent claims that are in accord with many of the basic properties of the underlying risk neutral process and yet better reflect the additional uncertainties and risks that exist in the black scholes merton paradigm

remittance income volatility and labor supply in mexico author affiliation catalina amuedo dorantes camuedod mail sdsu edu corresponding authorsusan pozo susan pozo wmich edu acknowledgment we would like to thank the anonymous referees and the editor for their comments and suggestions on how to improve the manuscript 1 background and significancea significant body of academic and policy research analyzes the impact of international remittances the earnings that emigrants send home in economies around the globe studies have been carried out to ascertain the effect of remittances on a wide range of economic outcomes including household decisions concerning capital accumulation health and housing expenditures country exchange rates economic growth income distribution poverty rates and as we do in this study labor supply evidence of the impacts of remittances on the well being of recipients and on economic progress is mixed some studies find that countries and households reap positive benefits from these resource transfers e g adam and page 2005 while others find negative or ambiguous effects e g narayan narayan and mishra 2011 an overall consensus on the impacts of remittances is unlikely to emerge for some time given the complexity of this research topic not to mention the varying characteristics of countries under analysis 1we propose to contribute to this important debate using an expanded approach for assessing the effects of remittances on individual and household decision making our contribution is to note that while the level of resource transfers received by the household is likely to influence individual and household behaviors volatility with regard to the stream of inflows is also likely to play an important role to date research on the impact of remittances on remittance receiving households has tended to focus on the way in which the level of remittance inflows affects either individual or household behavior without considering the volatility surrounding these inflows however if the volatility that surrounds remittance inflows influences individual and household behaviors a strategy that only examines the level of inflows is likely to miss out on a more complete understanding of the effects of remittances on individual and household decision making and therefore of their impacts on remittance receiving economies amuedo dorantes and pozo 2010 in this study we focus on the labor market and investigate how volatility of remittance inflows influences male and female labor supply a crucial dimension in the influence of remittances on remittance receiving countries limited numbers of studies have examined the impact of the incidence and level of remittance income on labor supply patterns although conclusions differ owing in part to the various data sources and methodological approaches being used a majority of the studies have concluded that the receipt of remittances results in labor supply reductions for instance rodriguez and tiongson 2001 report that remittances lower employment in the philippines while funkhouser 1992 estimates that remittances reduce the employment likelihood of nicaraguan men and women by 2 and 5 percentage points respectively studies by amuedo dorantes and pozo 2006 and hanson 2007 found that the impact of remittances on the labor supply of mexicans is conditioned on gender they conclude that mexican women reduce labor supply on account of remittance inflows whereas men do not in contrast limiting their study to mexican households that receive persistent remittances cox edwards and rodriguez oreggia 2009 conclude that remittances have no impact on the labor supply of household members remaining in mexico with the exception of urban women in traditionally low migration states for whom labor supply rises however we still lack an understanding of the ways in which the volatility in remittance inflows can impact labor supply in remittance receiving countries

integrated dynamic models for hedging international portfolio risks abstract we develop scenario based stochastic programming models for hedging the risks of international portfolios using options the models provide increasing level of integration in managing market and foreign exchange fx risks we start with a single stage model with currency options for selective hedging of fx risks while market risk is addressed through diversification we add stock options to hedge market risks and add quantos and currency options to develop an integrated model using an innovative method to price quantos on the scenario tree underpinning the stochastic program the models are extended to multi stage settings backtesting on market data over a 14 year period that includes the global financial crisis of 2008 we demonstrate the effectiveness of taking increasingly integrated views of risk management simultaneous hedging of market and fx risks using stock and currency options has the best ex post performance the differences are economically significant and statistical significance is established through rigorous hypothesis testing the models are particularly effective during the crisis test results show that two stage models outperform their single stage counterparts regardless of the hedging strategy

the modern history of exchange rate arrangements a reinterpretation we develop a novel system of reclassifying historical exchange rate regimes one key difference between our study and previous classifications is that we employ monthly data on market determined parallel exchange rates going back to 1946 for 153 countries our approach differs from the imf official classification which we show to be only a little better than random it also differs radically from all previous attempts at historical reclassification our classification points to a rethinking of economic performance under alternative exchange rate regimes indeed the breakup of bretton woods had less impact on exchange rate regimes than is popularly believed

the elusive curse of oil abstract our goal is to show that contrary to the claims made in several recent papers the effect of a large endowment of oil and other mineral resources on long term economic growth of countries has been on balance positive moreover the claims of a negative effect of oil and mineral wealth on the countries institutions are called into question

selecting a portfolio with skewness recent evidence from us european and latin american equity markets abstract polynomial goal programming in which investor preferences for skewness can be incorporated is utilized to determine the optimal portfolio from latin american us and european capital markets the empirical findings suggest that the incorporation of skewness into an investor s portfolio decision causes a major change in the resultant optimal portfolio the empirical evidence indicates that investors do trade expected return of the portfolio for skewness

remittances output and exchange rate regimes theory with an application to latin america immigrant remittances have a broad effect on the receiving economies we show this impact on the main macroeconomic aggregates is dependent on the policy arrangements in place that manage capital flows we look at remittance inflows in a small open economy to examine their influence on output under alternative exchange rate regimes using a simple stochastic limited participation model we are able to reproduce dynamics consistent with the empirical literature we find that the dynamics of labor inflation and output are dependent on the parameterization of the utility function and on the monetary rule governing the evolution of the interest rate and in particular with respect to the response of interest rates to exchange rate movements we find that the initial drop of output resulting from a remittances shock is similar under alternative exchange rate regimes but the subsequent recovery of output is faster and stronger under more flexible exchange rate regimes we provide suggestive empirical evidence from a panel vector autoregression specification for 17 latin american countries that corroborates our results
