international consumption risk sharing this paper formally examines the implications of international consumption risk sharing for a panel of industrialized countries we theoretically derive the international consumption insurance proposition in a simple setup and show how to modify it in more complicated models we analyze the implications of the theory for pairs of countries and find that aggregate domestic consumption is almost completely insured against idiosyncratic real demographic fiscal and monetary shocks over short cycles but that it covaries with these variables over medium and long cycles the cross equation restrictions imposed by the theory are rejected the policy implications are discussed

the output composition puzzle a difference in the monetary transmission mechanism in the euro area and u s we revisit recent evidence on how monetary policy affects output and prices in the u s and in the euro area the response patterns to a shift in monetary policy are similar in most respects but differ noticeably as to the composition of output changes in the euro area investment is the predominant driver of output changes while in the u s consumption shifts are significantly more important we dub this difference the output composition puzzle and explore its implications and several potential explanations for it while the evidence seems to point at differences in consumption responses rather than investment as the proximate cause for this fact the source of the consumption difference remains a puzzle

international portfolio reallocation diversification benefits and european monetary union abstract we investigate the determinants of bilateral international equity and bond portfolio reallocation across a large cross section of countries spanning over two sample periods 1997 2001 and 1997 2005 we find that the strongest drivers are the marginal diversification benefits arising from the pure asset component and the initial degree of underweight this evidence suggests that global portfolio reallocations over the asset boom and bust period were determined by optimal diversification considerations we also find that due to economic and monetary union emu the weight assigned by euro area investors to investment in euro area countries increased significantly in equity and fixed income portfolios with a trade diverting effect against the british bond market

regional insurance and migration a dynamic model of migration is developed to study whether labor mobility can hedge people against region specific shocks making private or public insurance redundant the model adopts a novel timing for migration which is argued to be the time frame suitable for analyzing risk sharing issues it also innovates on the existing literature by solving individual migration through convexification of the set of actions the results show that the role of migration as an insurance mechanism is small labor mobility cannot fully remove income differentials between regions it is also shown that a fiscal stabilization scheme is in general optimal moreover any pure risk sharing mechanism has no influence on migration flows

tastes and technology in a two country model of the business cycle explaining international trade on international financial markets allows people to insure country specific risk and smooth consumption intertemporally equilibrium models of business cycles with trade on global financial markets typically yield international consumption correlations near one and excessive volatility of investment the authors incorporate nontraded goods in the model and find that the implications for aggregate consumption investment and the trade balance are consistent with business cycle properties of industrialized countries however the model driven by technology shocks alone yields counterfactual implications for comovements between consumption and prices at the sectoral level taste shocks produce price quantity relationships more consistent with the data copyright 1995 by american economic association

state responses to fiscal crises the effects of budgetary institutions and politics this paper explores the dynamics of state taxes and spending during the late 1980s when regional economic downturns and increased expenditure demands led to substantial state budget deficits more restrictive state fiscal institutions such as no deficit carryover rules and tax and expenditure limitations are correlated with more rapid fiscal adjustment to unexpected deficits political factors are also important when a single party controls the state house and the governorship deficit adjustment is much faster than when party control is divided in gubernatorial election years tax increases and spending cuts are both significantly smaller than at other times

currency areas and voluntary transfers this paper discusses the relationship between the formation of a currency area and the use of voluntary fiscal transfers between countries we show that there is a trade off between the benefits of flexible exchange rates and the additional risk sharing benefits of voluntary transfers that can be sustained in a currency area we show that whether a currency area is beneficial or not will depend on the magnitude of economic parameter values in particular we show that in a simple two country model and for a plausible set of economic parameter values a currency area is optimal

exchange rate bands with price inertia this problem by committing member states to taking suitable action to prevent cross parities from straying outside some given publicly announced range and williamson s proposal for target zones was explicitly aimed at preventing exchange rate misalignment among the principal industrial countries subsequently the louvre accord struck between members of the group of seven in i 987 involved unpublished commitments designed to constrain fluctuation between the u s dollar and the currencies of its major trading partners funabashi i988 given the obvious practical importance of understanding the implications of such policy commitments for the economy in general and the exchange rate in particular it is perhaps not surprising that the seminal work by krugman i 988 i989 on exchange rate determination within a band has aroused considerable interest under the assumption that the velocity of money follows a brownian motion process he obtains an explicit solution for the exchange rate as a function of the fundamental which shows that the presence of a commitment to intervene so as to defend the band exerts a stabilising influence on the exchange rate even before any such intervention takes place in their contribution to this emerging literature froot and obstfeld i989 note that krugman s minimalist stochastic specification can be derived from a monetary model of exchange rates where prices are perfectly flexible and full employment prevails where international interest differentials match expected exchange rate changes and the exchange rate preserves purchasing power parity cf mussa 1976 and they show that the behaviour of the rate inside a currency band can be obtained using results on regulated brownian motion processes cf harrison i985 using the same framework and techniques flood and garber i989 indicate how the rate will respond to noninfinitesimal intervention and svensson i 989 examines the effect of bandwidth on the stochastic behaviour of interest rates klein i989 considers the effects of uncertainty about the width of the band

channels of interstate risk sharing united states 1963 1990 we develop a framework for quantifying the amount of risk sharing among states in the united states and construct data that allow us to decompose the cross sectional variance in gross state product into several components which we refer to as levels of smoothing we find that 39 percent of shocks to gross state product are smoothed by capital markets 13 percent are smoothed by the federal government and 23 percent are smoothed by credit markets the remaining 25 percent are not smoothed we also decompose the federal government smoothing into subcategories taxes transfers and grants to states

international capital mobility amongst the major industrialised countries too little or too much this paper examines capital flows among the major industrialized countries with a view to assessing m feldstein and c horioka s 1980 claim that international capital mobility is limited it argues that saving investment correlation tests are inherently flawed and proposes an alternative methodology for testing the degree of international capital mobility it finds that capital flows have been excessive in the sense that they are driven by speculative forces rather than by economic fundamentals copyright 1995 by royal economic society

a volatility based theory of fiscal union desirability abstract heterogeneous countries may rationally choose to form a currency union first and a fiscal union later we find and illustrate empirically for the emu countries reasonable volatility conditions under which this sequencing in the deepening process is indeed rationalizable changes in the distribution of expected income shocks require a reassignment of political weights to restore unanimous support for an added fiscal dimension the bargaining space depends on countries relative income size and cross correlation of shocks

cyclical and causal patterns of inflation and gdp growth empirical foundations for the view that high inflation impairs gdp growth are examined using annual data for 115 countries over the period 1960 1995 taking into account country heterogeneity and time specific symmetric shocks as well as endogeneity of inflation and dynamics of gdp growth dynamic panel data models of the effects of inflation on growth are estimated no evidence is found supporting the view that inflation is in general harmful to gdp growth on the other hand there is a negative correlation between contemporaneous intra country inflation and growth for periods characterized by positive oil price shocks

public expenditure under uncertainty the net benefit criteria public expenditure under uncertainty is modeled as the problem of determining the quantities of l public goods and m private goods to be provided to n consumers when the private goods are claims to a single commodity dollars which are contingent upon the occurrence of one of m possible states of nature a real valued net benefit function is identified and criteria based upon this function are provided that are both necessary and sufficient for pareto improving or pareto efficient solutions to this problem copyright 1992 by american economic association

global output growth and volatility spillovers this article examines discernable patterns of real gross domestic product gdp growth co movements across 29 countries using consistent time series data 1912 2008 of these countries only 12 are found to form three statistically significant groupings i e g6 six organization for economic co operation and development oecd european countries g4 four anglo saxon countries and g2 two major asian countries one may then conclude that inter alia geographical proximity cultural ties and the level of socio economic and financial ties among countries determine the global systematic co movements of growth rates our results indicate that any recession in the us initially engulfs other anglo saxon countries as well as g6 and g2 countries before exerting its adverse knock on effects to the rest of the world a multivariate generalized autoregressive conditional heteroscedasticity mgarch model is also used to examine the transmission of gdp growth across these three groups and their corresponding vol

labour market rigidities and international risk sharing across oecd countries abstract in this paper we examine the role of labour market rigidities in the context of international consumption risk sharing stronger labour market regulation may make it easier to borrow against future income thus allowing shocks to be smoothed to a greater extent in addition rigid labour markets may help to enforce implicit contracts that shift risk from employees to owners of firms who in turn may diversify risk internationally using data for 19 oecd countries we show that labour market rigidities significantly increase consumption correlations and reduce the exposure to country specific shocks these results suggest that labour market rigidities improve the international sharing of consumption risks by fostering a more efficient intra national allocation of risk

international risk sharing and european monetary unification abstract we explore income and consumption smoothing patterns among european community ec countries and among oecd countries during the period 1966 90 we find that for oecd as well as for ec countries about 40 percent of shocks to gdp are smoothed at the one year frequency with about half the smoothing achieved through national government budget deficits and half by corporate saving at the three year differencing frequency only 25 percent of shocks to gdp are smoothed mainly via government lending and borrowing in the absence of alternative income and consumption smoothing mechanisms the restrictions on budget deficits imposed by the maastricht treaty should be relaxed to allow governments to run large temporary deficits in response to output shocks

labour market institutions and household consumption insurance within oecd countries this paper tests empirically whether the effect of idiosyncratic income shocks on aggregate consumption depends on institutional features of national labour markets the results show that in a sample of 15 oecd countries institutional heterogeneity is a significant determinant of the response of household consumption to country specific income shocks this is consistent with the idea that institutionally provided social insurance may help increase income stability when people differ in their ability to access financial markets and smooth consumption fluctuations

risk sharing between and within families this paper uses the panel study of income dynamics to test whether risk sharing is complete between or within american families the tests accommodate a wide variety in the configuration and availability of family data the test results reject inter as well as intra family full risk sharing even assuming that leisure is endogenous or that leisure and consumption are nonseparable

fiscal flows in the united states and canada lessons for monetary union in europe regional flows of federal taxes and transfers within the united states and canada are used to analyze long term fiscal flows the redistributive element and short term responses to regional business cycles the stabilization element in the united states long run flows amount to 22 cents in the dollar while the stabilization effect is 31 cents in the dollar in canada the redistributive effect is larger 39 cents and the stabilization effect smaller 17 cents federal flows appears to depend on the institutional structure of the country concerned however in both countries the redistributive element is considerably larger than the amounts involved in the ec structural funds program as for stabilization national fiscal policies in the ec appear to have been as effective as federal governments in the united states and canada in cushioning shocks to incomes

are output fluctuations transitory according to the conventional view of the business cycle fluctuations in output represent temporary deviations from trend the purpose of this paper is to question this conventional view if fluctuations in output are dominated by temporary deviations from the natural rate of output then an unexpected change in output today should not substantially change one s forecast of output in say five or ten years our examination of quarterly postwar united states data leads us to be skeptical about this implication the data suggest that an unexpected change in real gnp of 1 percent should change one s forecast by over 1 percent over a long horizon

welfare gains from international risksharing abstract this paper uses consumption data to compute yet unexploited welfare gains that can be achieved through risksharing among twenty oecd countries there is both aggregate national consumption risk and nondiversifiable individual specific risk countries engage in an optimal risksharing arrangement to pool risk associated with the aggregate consumption endowment streams welfare gains are associated with reduced consumption variability and with the international pricing of the consumption streams of individual countries the paper considers the standard vnm time additive preferences as well as nonexpected utility and habit formation preferences large unexploited gains are found under all sets of preferences leading to an international risksharing puzzle

redistribution and risk sharing in italy learning from the past abstractredistribution and risk sharing in italy learning from the past regional studies this paper investigates the role of public policies in italy by assessing both the redistribution and the risk sharing functions of interregional net fiscal flows in the long run its comparative approach allows one to contrast results obtained for two periods characterized by diverse regional policy and dynamics of regional convergence although based on a specific example the evidence supports more general conclusions when assessing the regional redistributive and risk sharing power of national fiscal policies many different factors related to the existing policy regime should be accounted for particularly the distribution of government spending between current expenditure and public investment

what can explain the apparent lack of international consumption risk sharing recent research in international business cycles finds that international consumption comovements do not match the risk sharing predictions of standard complete markets models in this paper i ask whether two different types of explanations can help explain this result 1 nonseparabilities between tradables and nontradable leisure or goods and 2 the effects of capital market restrictions on consumption risk sharing i find that risk sharing cannot be resolved by either explanation alone however when i allow for both nonseparabilities and certain market restrictions risk sharing among unrestricted countries cannot be rejected this evidence suggests that a combination of these two effects may be necessary to explain consumption risk sharing across countries

evaluating risky consumption paths the role of intertemporal substitutability abstract in dynamic stochastic welfare comparisons a failure clearly to distinguish between risk aversion and intertemporal substitutability can result in misleading assessments of the impact of risk aversion on the welfare costs of consumption risk changes the problem arises in any setting in which uncertainty is propagated over time notably but not exclusively in economies with stochastic consumption trends regardless of the preference setup adopted an increase in risk aversion amplifies the per period costs of risks the weights consumers use to cumulate the per period costs of risks with persistent effects should however depend on intertemporal substitutability as well as on risk aversion under time separable expected utility preferences an increase in the period utility function s curvature therefore alters the welfare effect of risk for reasons that are in part unrelated to risk aversion to illustrate these points i reconsider lucas s estimate of the cost of consumption instability for the postwar united states

causal relationship between energy consumption and gdp growth revisited a dynamic panel data approach abstract this paper uses the panel data of energy consumption and gdp for 82 countries from 1972 to 2002 based on the income levels defined by the world bank the data are divided into four categories low income group lower middle income group upper middle income group and high income group we employ the gmm sys approach for the estimation of the panel var model in each of the four groups afterwards the causal relationship between energy consumption and economic growth is tested and ascertained we discover a in the low income group there exists no causal relationship between energy consumption and economic growth b in the middle income groups lower and upper middle income groups economic growth leads energy consumption positively c in the high income group countries economic growth leads energy consumption negatively after further in depth analysis of energy related data the results indicate that in the high income group there is a great environmental improvement as a result of more efficient energy use and reduction in the release of co2 however in the upper middle income group countries after the energy crisis the energy efficiency declines and the release of co2 rises since there is no evidence indicating that energy consumption leads economic growth in any of the four income groups a stronger energy conservation policy should be pursued in all countries

long run impacts of inflation across sectors in a small sample of countries this article investigates the long run effects of inflation on economic output for 10 sectors of the economy with a sample of 7 countries the analysis is done using long run restrictions in a vector autoregression and reports long run multipliers with bootstrapped confidence bands the results suggest that some sectors seem to be affected differently than others as well as significant heterogeneity across countries the results suggest the strongest effects in the low inflation countries germany and japan as has been found in similar studies in contrast to research using growth regressions the evidence suggests a positive long run effect of inflation on output

consumption smoothing channels in open economies abstract many intertemporal open economy macro models imply a theory of consumption smoothing channels thus we build an empirical model to analyze the intertemporal smoothing role of saving components fixed investments inventories and trade balance through the use of var impulse responses to different types of shocks we find that for the oecd countries the bulk of intertemporal smoothing has been carried out domestically via gross fixed investments and inventories but the trade balance has also played a relevant albeit volatile smoothing role we also characterize the dynamic behavior of each component the trade balance and inventories are mostly used as short run smoothing tools while fixed investment provides more and more smoothing over time we can also address some empirical puzzles such as the excess sensitivity of investment anomaly glick r rogoff k 1995 global versus country specific productivity shocks and the current account journal of monetary economics 35 159 192 and the saving investment correlation puzzle feldstein m horioka c 1980 domestic saving and international capital flows economic journal 90 314 329

strategic interactions of fiscal policies in europe a global var perspective abstract the paper analyses the strategic interactions of fiscal policies in the european union context by modelling the interdependencies arising between public and private sectors saving investment balances in a global vector autoregressive framework we use two empirical specifications to reflect some important differences in the sequencing of the policy decision making process in this setting we draw policy implications with respect to fiscal policy coordination and fiscal policy discretion we highlight the importance of several factors such as global capital flows uncertainty with respect to policy actions and nature of the shocks as key elements defining the dimension of the prevailing policy tradeoffs

dynamic risksharing in the united states and europe abstract we use a panel var model to improve upon the existing methodologies to analyze interregional risksharing and consumption smoothing channels first we endogenize the output process within a more general multi equation framework capturing the dynamic feedback between output and various smoothing channels second in line with dynamic general equilibrium open economy models of risksharing we exploit impulse response functions to trace the role of each smoothing channel over time in the presence of different structural shocks temporary vs permanent and output vs smoothing channels in the application to the us and oecd countries we find different dynamic properties of different smoothing channels we compare our results with the predictions of standard risksharing and consumption theories and tackle some of the puzzles in the literature such as the international risksharing puzzle and the consumption output correlation puzzle we are also able to address such policy issues as whether fiscal stabilizers have been substitutes or complements for financial market diversification activities and whether further financial market integration is likely to provide countries with more shock absorption tools a key result is the strong substitutability between capital and credit smoothing in the us and between fiscal and credit smoothing in the oecd

correlated jumps in crude oil and gasoline during the gulf war this article employs a bivariate poisson jump model to investigate the relationship between the volatility of crude oil and gasoline especially during the period of the gulf war we find that greater jumps occurring in crude oil returns will appear in gasoline returns at the same time but the magnitude of the co movements in volatility falls the covariance is relatively smaller in the second gulf war vs the first conflict the volatility of crude oil is of significantly high levels during periods of the war yet the volatility of gasoline is not as sensitive as crude oil particularly in the second conflict furthermore the jump that occurred by the war did not lead both spot prices to a high persistent level for a long period which fits the feature of the jump models all these findings are important to market traders and hedging strategies

full insurance in the presence of aggregate uncertainty this paper tests implications of full consumption insurance the object is to determine how much mileage can be obtained from a model with complete markets with such features as private information or liquidity constraints omitted the implication exploited is that individual consumption responds to aggregate risk but not to idiosyncratic risk the test involves regressing the change in household consumption onto the change in aggregate consumption and other right hand side variables such as the change in household income and change in employment status all variables other than the change in aggregate consumption are predicted to be insignificant in explaining the change in household consumption with observations on consumption and income for 10 695 households from the consumer expenditure survey the results are mixed the results for one specification exponential utility are mostly consistent with full consumption insurance the results for the other specification power utility are not

household choices in equilibrium this paper is an empirical investigation of equilibrium restrictions on household consumption and male labor supply it exploits a simple factor structure rationalized by two assumptions that household allocations are pareto optimal and that the labor market is competitive the paper estimates household preferences and tests how well this parsimonious factor structure represents panel data on married couples and time series data on asset returns most of the estimates are roughly comparable to those found in previous work no evidence against the simple factor representation is found and the intertemporal capital asset pricing model is not rejected copyright 1990 by the econometric society

a simple test of consumption insurance are consumers effectively insured against idiosyncratic shocks to income or wealth either by formal institutions such as charities private insurance and government programs or by informal mechanisms such as gifts and loans from relatives friends and neighbors under full insurance consumption growth should be cross sectionally independent of idiosyncratic variables that are exogenous to consumers this proposition is tested by cross sectional regressions of consumption growth on a variety of exogenous variables full insurance is rejected for long illness and involuntary job loss but not for spells of unemployment loss of work due to strike and an involuntary move

on the empirics of risk sharing across mena countries in this article we compute the potential welfare gains and the realized gains from risk sharing among middle east and north african mena countries including the oil rich gulf region and the resource scarce economies we find that the overall potential welfare gains across mena countries are positive for all countries under the assumption of full risk sharing the potential welfare gains among the six gulf cooperation council gcc countries are positive even though the magnitudes are smaller compared to those of the rest of the mena region we also quantify the extent of risk sharing for the mena region and show that it is significant for the mena region and its subgroups however we could not find any sign of inter temporal smoothing across the same groups decomposing the aggregate output shocks shows that the extent of risk sharing is significant when only positive output shocks exist across the resource scarce mena economies however we observe that gcc countries share output risks with each oth

domestic savings and intra national capital flows abstract regional british data on savings and investment are shown to be uncorrelated consistent with the hypothesis of perfectly mobile intra national capital flows

securitization of mortgage debt domestic lending and international risk sharing securitization makes mortgage related risks internationally tradeable and thus contributes considerably to the international diversification of macroeconomic risk in the years 2003 2008 the increase in international cross holdings of securitized mortgage debt has lowered industrialized countries conditional consumption volatility relative to the united states by about 10 15 percentage points we turn to the role of domestic credit in explaining this result domestic credit leads to better international risk sharing only if debt is securitized and traded internationally conversely the risk sharing benefits from securitization seem to evaporate if credit dries up as it did in the recent financial crisis la titrisation fait que les risques attaches aux hypotheques peuvent etre transiges internationalement voila qui contribue de maniere significative a la diversification internationale des risques macroeconomiques dans les annees 2003 2008 l accroissement dans la dette hypothecaire titrisee detenue dans d autres pays a reduit la volatilite de la consommation relative par rapport aux etats unis des pays industrialises de 10 15 points de pourcentage on examine le role du credit domestique dans l explication de ce resultat on montre que le credit domestique entraine un meilleur partage international du risque seulement si la dette est titrisee et negociee internationalement a contrario les avantages de la titrisation semblent s evaporer si le credit s asseche comme ce fut le cas dans la recente crise financiere

risk sharing role of foreign aid in developing countries abstractthe effects of foreign aid on economic growth have been extensively investigated over the past 40 years however even though foreign aid can be a significant source of insurance against do

diversification cost structure and the risk premium of multinational corporations we investigate theoretically and empirically the relationship between the geographic structure of a multinational corporation and its risk premium our structural model suggests two channels on the one hand multinational activity offers diversification benefits risk premia should be higher for firms operating in countries where shocks co vary more with the domestic ones second hysteresis and potential losses induced by fixed and sunk costs of production imply that risk premia should be higher for firms operating in countries where is costlier to enter our empirical analysis confirms these predictions and delivers a decomposition of firm level risk premia into indi

why is capital so immobile internationally possible explanations and implications for capital income taxation the evidence on international capital immobility is extensive including the lack of international portfolio diversification real interest differentials across countries and the high correlation between domestic savings and investment the authors develop a model with asymmetric information between countries that helps rationalize all the above observations and then examine the implications of this model for optimal domestic tax policy without asymmetric information past work showed that small open economies should not impose corporate income taxes with asymmetric information the optimal policy instead involves government subsidies to capital imports some omitted factors that argue against subsidizing capital imports are explored briefly copyright 1996 by american economic association

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

is consumption insufficiently sensitive to innovations in income deaton 1986 has noted that if income is a first order autoregressive process in first differences then a simple version of friedman s permanent income hypothesis spih implies that measured u s consumption is insufficiently sensitive to innovations in income this paper argues that this implication of the spih is a consequence of the fact that it ignores the role of the substitution effect in the consumption decision using a parametric version of the standard model of economic growth the paper shows that very small movements in interest rates are sufficient to induce an empirically plausible amount of consumption smoothing since an overall evaluation of the model s explanation for the observed smoothness of consumption requires examining its implications for other aspects of the data the paper also explores some of these

international real business cycles we ask whether a two country real business cycle model can account simultaneously for domestic and international aspects of business cycles with this question in mind we document a number of discrepancies between theory and data the most striking discrepancy concerns the correlations of consumption and output across countries in the data outputs are generally more highly correlated across countries than consumptions in the model we see the opposite

fiscal federalism and monetary unions a quantitative assessment abstract in this paper i provide a quantitative analysis of three different forms of fiscal federalism in monetary unions fully decentralized regional fiscal authorities as the benchmark fiscal equalization with nominal tax revenue sharing and a common central fiscal authority i assess the capability of the different arrangements to stabilize regional consumption output and employment over the business cycle i also study the implications for interregional income consumption risk sharing and welfare from this analysis the following results emerge first a central fiscal authority stabilizes consumption fluctuations and increases the scope of interregional income and consumption risk sharing second fiscal equalization destabilizes consumption fluctuations and also reduces the scope of interregional income and consumption risk smoothing third a central fiscal authority leads to welfare gains whereas fiscal equalization leads to welfare losses

does financial globalization promote risk sharing article i nfo in theory one of the main benefits of financial globalization is that it should allow for more efficient international risk sharing in this paper we provide an empirical evaluation of the patterns of risk sharing among different groups of countries and examine how international financial integration has affected the evolution of these patterns using a variety of empirical techniques we conclude that there is at best a modest degree of international risk sharing and certainly nowhere near the levels predicted by theory in addition only industrial countries have attained better risk sharing outcomes during the recent period of globalization developing countries have by and large been shut out of this benefit even emerging market economies many of which have reduced capital controls and all of which have witnessed large increases in cross border capital flows have seen little change in their ability to share risk we find that the composition of flows may help explain why emerging markets have not been able to realize this presumed benefi to f financial globalization in particular our results suggest that portfolio debt which had dominated the external liability stocks of most emerging markets until recently is not conducive to risk sharing
