Risk sharing through capital gains

Abstract We estimate channels of international risk sharing between European Monetary Union (EMU), European Union, and other OECD countries, 1992–2007. We focus on risk sharing through savings, factor income flows, and capital gains. Risk sharing through factor income and capital gains was close to zero before 1999 but has increased since then. Risk sharing from capital gains, at about 6%, is higher than risk sharing from factor income flows for European Union countries and OECD countries. Risk sharing from factor income flows is higher for euro zone countries, at 14%, reflecting increased international asset and liability holdings in the euro area.     

Foreign portfolio diversification and risk-sharing

We investigate income smoothing associated with international portfolio diversification by decomposing the net factor income (NFI) channel into interests, dividends and retained earnings, for OECD and EU countries. We find that interest receipts and equity dividend payments contribute significantly to absorb domestic income shocks. Geographically concentrated portfolios and, in particular, biases toward EU markets have a strong negative effect on the degree of risk-sharing.     

Intra- and international risk-sharing in the short run and the long run

We investigate empirically how industrialized countries and US states share consumption risk at horizons between 1 and 30 years. US federal states share about 50% of their permanent idiosyncratic risk through cross-state capital income flows. While insurance against transitory fluctuations in output is virtually complete, OECD countries do not share any of their permanent idiosyncratic risk. Our results suggest that purely transaction cost based theories cannot explain the home bias, since the potential welfare gains from insurance against permanent shocks would by far outweigh that of insuring against transitory variation. We conclude that permanent and transitory shocks constitute two qualitatively different kinds of risk and that various forms of endogenous market incompleteness may render permanent shocks a lot harder to insure, in particular at the international level.     

A model of relative national price levels under pricing to market

This paper proposes an alternative to the Balassa-Samuelson theory of how relative price levels between countries are determined. The theory is a general equilibrium formulation of a model where pricing to market arises endogenously from firm decisions. It differs from Balassa-Samuelson in that it centers on the distinction between segmented national goods markets rather than the distinction between traded and nontraded goods. The paper also explores how Balassa-Samuelson might be updated by combining it together with pricing to market elements. Applied to the case of a monetary union, the theory offers an alternative explanation for the inflation differentials observed in EMU. It implies that such differentials may be a natural and enduring feature of a monetary union in which markets for goods and labor are less than fully integrated.     

Are valuation effects desirable from a global perspective?

Recent studies have emphasized the role of valuation effects due to exchange rate movements in easing the process of adjustment of the external balance of a country. This paper asks to what extent valuation effects are desirable from a global perspective as a mean to achieve an efficient allocation of resources. In a frictionless world, it is desirable to have large movements in prices and exchange rates. But once a small degree of price rigidity is introduced not only should prices be stabilized but also the response of the exchange rate should be muted. There is a minor role for valuation effects that depends both on the size and composition of assets and liabilities.     

Exchange rates and trade: How important is hysteresis in trade?

This paper looks at the responsiveness of a country's export supply to exchange rate changes and measures its quantitative importance by breaking down export adjustments between changes in output levels by existing exporters (intensive margin) and movements due to changes in the number of exporters (extensive margin). Using data on a representative sample of Spanish manufacturing firms, the paper finds sunk costs hysteresis in entry and exit to be an important factor in determining export market participation, but unrelated to exchange rate uncertainty. The sunk costs of entering the market appear to be much larger than the costs of exiting the market. Finally, although hysteresis exists, its effect on the responsiveness of aggregate trade volumes to exchange rate changes is quantitatively small. A 10% home currency depreciation results in an increases in export volume due to the increase in the number of exporting firms of only 1.4% of export volume.     

FEAR OF FLOATING IN EAST ASIA?

Abstract.  We examine the de facto exchange rate arrangements in eight East Asian countries during the post-Asian crisis period. The empirical results suggest that three countries adopted a hard peg or a peg with capital account restrictions, whereas five countries moved toward a more flexible exchange rate arrangement in the post-crisis period. Three of these five countries (Korea, Indonesia and Thailand) achieved a level of exchange rate flexibility close to the level accomplished in a free floater such as Australia. These results suggest that 'fear of floating' in East Asia is not prevalent in the post-crisis period, supporting the bipolar view of the optimal exchange rate regime.     

European monetary union, adjustment, and exchange rate variability

This paper uses a three-country, three-good, factor-specific model of trade with wage rigidities to investigate how European Monetary Union is likely to affect exchange rate variability. Focusing on international macroeconomic adjustment under both exogenous and optimizing monetary policies, it shows that the relative variability (against external currencies) of the euro and a basket of predecessor currencies depends on the relative sizes and specialization patterns of countries and the relative importance of different shocks. Monetary union is likely to decrease (increase) aggregate European exchange rate variability for shocks to industries in which large (small) euro area countries specialize.     

A new approach to capital flows: Theory and evidence

This paper examines how an open economy determines its financial openness and deals with volatile capital flows when deciding to utilize them for output growth. We find that higher economic instability is an inevitable price paid for faster growth if a country permits wider openness without reversing its financial vulnerability. We prove that the country can leave its capital market wider open to achieve higher growth and lower instability if its financial system has been strengthened substantially. We show why some financially advanced countries request reluctant developing countries to liberalize their immature markets and how the conflict of interest between the two parties is formulated. The paper also presents a large sample of cross-country experiences with tradeoffs between growth and instability, with the observed evidence supporting our theoretical predictions.     

Does financial globalization promote risk sharing?

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 benefit of 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.     

Systems GMM estimates of the Feldstein–Horioka puzzle for the OECD countries and tests for structural breaks

A systems GMM estimation method is used to estimate the Feldstein–Horioka equation from 1960 to 2007 with a panel of 13 OECD countries. It is found that the Feldstein–Horioka puzzle exists in a weaker form with a much reduced saving retention coefficient. The Bretton Woods agreement in particular seems to have weakened the Feldstein–Horioka puzzle by significantly improving international capital mobility. In comparison the Maastricht agreement seems to have improved capital mobility only by a small magnitude. The Blundell and Bond systems GMM method and structural break tests of Mancini-Griffoli and Pauwels are used in this paper.
