Increasing Returns,Financial Capital Mobility and Real Exchange Rate Dynamics*

The late 1990s saw a US IT investment boom, large capital flows into the USA and an appreciation of the US$. At the time, this appeared to be driven by expectations of continued IT‐related knowledge spillover externalities and associated productivity and profit growth. Using a two‐region dynamic general equilibrium model with externalities, we find a once‐off productivity shock leads to capital inflow and a real appreciation only in the short term. In the long term, capital flows stabilise and the real exchange rate depreciates. For a single shock to trigger long‐term growth in capital flows requires unrealistically large externalities.     

Growth and risk at the industry level: The real effects of financial liberalization

This paper analyzes the effects of financial liberalization on growth and volatility at the industry level in a large sample of countries. We estimate the impact of liberalization on production, employment, firm entry, capital accumulation, and productivity. In order to overcome omitted variables concerns, we employ a number of alternative difference-in-differences estimation strategies. We implement a propensity score matching algorithm to find a control group for each liberalizing country. In addition, we exploit variation in industry characteristics to obtain an alternative set of difference-in-differences estimates. Financial liberalization is found to have a positive effect on both growth and volatility of production across industries. The positive growth effect comes from increased entry of firms, higher capital accumulation, and an expansion in total employment. By contrast, we do not detect any effect of financial liberalization on measured productivity. Finally, the growth effects of liberalization appear temporary rather than permanent.     

Cross-border mergers and acquisitions and the role of trade costs

Cross-border mergers and acquisitions (M&As) have increased dramatically over the last two decades. This paper analyses the role of trade costs in explaining the increase in the number of cross-border M&As. In particular, we distinguish horizontal and non-horizontal M&As and investigate whether trade costs affect these two types of mergers differently. We analyse this question using industry data for 23 OECD countries for the period 1990-2001. Our findings suggest that while in the aggregate trade costs affect cross-border merger activity negatively its impact differs importantly across horizontal and non-horizontal mergers. The impact of trade costs is less negative for horizontal mergers, which is consistent with the tariff-jumping argument.     

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.     

Composition of International Assets and the Long‐run Current Account

We document the role of capital gains and losses for the current account that a country can sustain along a balanced growth path. While it is well know that growth allows a country to run a current account deficit and still keep its external debt stable as a share of GDP, the sensitivity of the current account to the composition of external assets and liabilities has received little attention. We show that this composition matters because several assets, such as equity or FDI, earn substantial capital gains that are not reflected in the current account. A country that is a net creditor in such assets can then sustain a larger current account deficit. Using a broad sample, we show that this aspect substantially tilts estimates of the long‐run current account towards a deficit among industrialized economies, with the opposite situation for emerging markets. We also show that industrialized economies are likely to benefit from predictable capital gains in the future.     

Income and consumption smoothing and welfare gains across Pacific Island Countries: The role of remittances and foreign aid

We examine the potential welfare gains and channels of income smoothing for Pacific Island Countries (PICs) and find that, under full risk sharing overall welfare gains across all PICs (particularly, Kiribati, Palau, and Papua New Guinea) are at desirable levels. However, for Australia, the potential welfare gain from risk sharing is almost similar to the gain it obtains if Australia attains full risk sharing with the rest of the OECD countries or with New Zealand alone. We also break down output using the framework of Sørensen and Yosha (1998) to quantify the extent and channels of risk sharing across PICs. For PICs, income-smoothing channels (net factor income and current transfers) play a significant role in buffering the output shock compared to the performance of those channels on smoothing the output shock for OECD countries. Domestic savings also smooth a fair portion of shocks to output, but the extent is much lower compared to that of OECD countries. Further, we analyze the effect of remittances and foreign aid on income smoothing for the PICs excluding Australia and New Zealand. Income smoothing via remittances is highly volatile and significant in recent years, while foreign aid seems to be a stronger and more stable channel for smoothing domestic output shocks for PICs.     

SECTORAL EXCHANGE RATE PASS-THROUGH: TESTING THE IMPACT OF POLICY REFORMS IN INDIA

This paper analyses the impact of India's policy reforms on exchange rate pass‐through into import and export prices, using panel data (at one‐digit SITC level) for pre‐ (1980–90) and post‐reform (1991–2001) periods. While the pass‐through into import prices has declined, the pass‐through into export prices (in USD terms) has increased during the 1990s. The results suggest that, relative to rupee depreciation, Indian exporters increased their USD prices around 20% in the 1980s, but decreased them by around 70% in the 1990s. Moreover, the number of sectors exhibiting some degree of pass‐through increased in the 1990s (six), relative to the 1980s (three). These changes may be attributable to the elimination of currency and trade controls, which increased competition among firms and fostered a concern with market share gains in the 1990s over an attempt to use depreciations to increase profits in the 1980s.     

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.     

The Impact of a Disorderly Resolution of Global Imbalances on Global Wealth

Partly reflecting structural advantages such as liquidity and strong investor protection, foreigners have built up extremely large positions in US (as well as other dollar‐denominated) financial assets. This paper describes the impact on global wealth of an unanticipated shock to US financial markets. For every 10 per cent decline in the dollar, US equity markets, and US bond markets, total wealth losses to foreigners could amount to about 5 percentage points of foreign GDP. Four stylized facts emerge: (i) foreign countries, particularly emerging markets, are more exposed to US bonds than to US equities; (ii) over time US exposure has increased for most countries; (iii) on average, US asset holdings of developed countries and emerging markets (scaled by GDP) are very similar; and (iv) based on their reserves position alone, wealth losses of emerging market governments could on average amount to about 2¾ percentage points of their GDP.     

Does complexity explain the structure of trade?

This paper analyzes whether complexity, measured by the number of skilled tasks that are performed in production, explains countries’ commodity trade structure. We modify the Romalis ( 2004 ) model to incorporate advantage differences in complexity across commodities together with differences in the number of mistakes made by workers in the production process in developed and developing countries as a source of comparative advantage. Our model predicts that the share of developed countries in world trade increases with products’ complexity. Empirical tests confirm this prediction. Moreover, we find that complexity complements the explanation provided by skill‐intensity on countries’ commodity trade structure.     

Capital mobility, skill formation and polarization

We bring in hierarchical education and skill formation within a standard Jonesian specific-factor model of production and trade for a developing economy. There are three types of labor, unskilled, medium skilled and high-skilled. The unskilled can only develop into medium-skilled and medium-skilled into high-skilled. As capital becomes internationally mobile, educational capital gets concentrated in particular types of education. In the process the society gets polarized between the highly educated and the absolutely uneducated.     

Income insurance and the determinants of income insurance via foreign asset revenues and foreign liability payments

We document that the net factor income smoothing channel in OECD countries is primarily driven by net financial asset income, while the other two sub‐components (net compensation of employees and net taxes on imports) turn out to be ineffective. Once factor income inflows are distinguished from outflows, empirical evidence suggests a non-significant effect of inflows in terms of income smoothing as opposed to a positive and significant role of factor income outflows. Factor income outflows also appear to be robust with respect to positive output shocks, while neither factor inflows nor factor outflows provide insurance against negative output shocks. In terms of the determinants of income smoothing, results indicate that an increase in foreign equity and debt liabilities positively affect the extent of smoothing via factor income outflows. Whereas, contrary to the current literature, an increase in foreign asset holding does not have a positive impact on smoothing via factor income inflows. European investors' tendency of allocating a sizeable portion of their assets within the Euro zone is shown to undermine income smoothing.     

Policy commitment and the welfare gains from capital market liberalization

This paper evaluates the quantitative impact of capital liberalization on the taxation structure and welfare of the liberalizing countries when governments conduct fiscal policy optimally but without commitment (time-consistent policies). The transition from a regime of capital autarky to a regime of free mobility leads to a decrease in the long-term tax rate on capital of 13 percent and an increase in the tax rate on labor of 2 percent. As a consequence of this taxation shift, welfare increases by about 1 percent. The reduction in capital taxation induced by capital market liberalization is welfare improving because, in the absence of capital mobility, the time-consistent policies over-tax capital.     

On the emergence of an MFN club: equal treatment in an unequal world

Abstract .  Motivated by GATT, we endogenize the formation of a club whose members have to abide by the MFN principle of non-discrimination. The underlying model is that of oligopolistic intraindustry trade. While an MFN club does not alter average tariff levels across countries, it increases aggregate world welfare; makes non-members worse off; and can immiserize its high cost members. These results imply that (i) core WTO rules such as MFN are valuable even if multilateral negotiations deliver limited trade liberalization and (ii) the distributional effects of MFN maybe one reason why developing countries have been granted Special and Differential treatment at the WTO.
