The current account as a dynamic portfolio choice problem

The current account can be understood as the outcome of investment decisions made by domestic and foreign investors. These decisions can be decomposed into portfolio rebalancing and portfolio growth components, as highlighted by theoretical models. The empirical literature draws attention to the relative importance of portfolio rebalancing to explain fluctuations in capital flows, although they do not shed light on the mechanisms behind these rebalancing effects. In this paper, we provide empirical evidence of the importance of portfolio rebalancing driven by changes in investment opportunities for the dynamics of the current account. In particular, we evaluate the predictions of a partial-equilibrium model of the current account with dynamic portfolio choices, in which portfolio rebalancing is driven by changes in expected asset returns. Focusing on the dynamics of the current account between Japan and the US, we find evidence supporting innovations in investment opportunities as an important mechanism to explain international capital flows.     

The Simple Analytics of Sudden Stops

Currency crises in emerging and developing countries have often been characterized by “sudden stops” of capital flows. A variety of mechanisms have been adduced to explain the emergence of this phenomenon. This paper integrates these mechanisms into a simple and transparent analytical model in which currency mismatches, large current account deficits, and large stocks of short-term debt interact with low reserve stocks to generate dual equilibria. In this context, the “panic” equilibrium is characterized by a currency crisis, a sudden stop, and an output collapse. The potential for various policies to avoid this outcome is explored, as are the implications of the analysis for reserve accumulation.     

FDI promotion through bilateral investment treaties: more than a bit?

Policy makers in developing countries have increasingly pinned their hopes on bilateral investment treaties (BITs) in order to improve their chances in the worldwide competition for foreign direct investment (FDI). However, the effectiveness of BITs in inducing higher FDI inflows is still open to debate. It is in several ways that we attempt to clarify the inconclusive empirical findings of earlier studies. We cover a much larger sample of host and source countries by drawing on an extensive data set on bilateral FDI flows. Furthermore, we account for unilateral FDI liberalization, in order not to overestimate the effect of BITs, as well as for the potential endogeneity of BITs. Employing a gravity-type model and various model specifications, including an instrumental variable approach, we find that BITs do promote FDI flows to developing countries. BITs may even substitute for weak domestic institutions, though probably not for unilateral capital account liberalization.     

The saving–investment correlation and origins of productivity shocks

This paper shows how savings and investment can be positively correlated despite capital being perfectly mobile across countries. The saving-investment (SI) correlation depends on the origin and the volatility of macroeconomic (productivity) shocks, the persistence of these shocks and country-size. Simulating a two-country Real Business Cycle (RBC) model we show that as the variance of common shocks increases (relative to country-specific shocks), as the persistence of these shocks decreases and as country-size increases, the SI correlation increases. Using annual data from 1960 to 2002, productivity changes in 11 OECD countries are decomposed into common and country-specific shocks (from which foreign shocks are also constructed). The empirical findings show that the 11 countries share a statistically significant common component in productivity changes and common shocks generally account for at least half of the variations in the countries’ productivity changes. We then use the estimated variances of the shocks, in addition to each country's size, in the RBC model to compute the predicted SI correlation for each country, under the assumption that capital is perfectly mobile. The predicted SI correlation is then compared to the actual correlation to assess the relative degree of capital mobility in the 11 countries. The findings indicate that Norway, the Netherlands and the US have the highest degree of capital mobility whereas in Canada, Sweden, Belgium and Japan capital mobility has been the lowest.     

Exchange rate expectations and foreign direct investment flows

Exchange Rate Expectations and Foreign Direct Investment Flows. — Theories about exchange rate expectations are difficult to check empirically. We study FDI data to find indirect evidence on the formation of exchange rate expectations by foreign direct investors. Using panel data techniques on exchange rate movements and FDI flows from the United States to 20 OECD countries we find that skewness of devaluations has a robust positive impact on FDI flows while average devaluation and its volatility do not. We view this evidence as consistent with the hypothesis that relatively large exchange rate movements generate mean-reverting long-run expectations. This finding is consistent with survey-based evidence on exchange rate expectations.     

An Empirical Analysis on Capital Flows: The Case of Korea and Mexico

This paper discusses causes of capital flows in Korea and Mexico. Both countries received substantial amounts of foreign capital in the late 1980s and early 1990s. International capital helped these countries achieve a higher standard of living and faster economic growth. However, undesirable macroeconomic effects such as appreciation of real exchange rate and widening current account deficits usually accompany foreign capital inflows. The vector autoregressive (VAR) method is applied to investigate the underlying shocks causing the capital inflows. The main findings are that the U.S. business cycle and shocks to foreign interest rates account for more than 50% of capital inflows to both countries in the past two decades.     

Saving,investment and international capital mobility in East Asia

This paper estimates the degree of international capital mobility in East Asia using the saving–investment correlation originated in Feldstein and Horioka [Feldstein, M., Horioka, C., 1980. Domestic saving and international capital flows. Economic Journal 90, 314–329]. We apply the empirical method used in Kim [Kim, S.H., 2001. The saving–investment correlation puzzle is still a puzzle. Journal of International Money and Finance 20, 1017–1034] to control for cyclical effects in estimating a time-series saving–investment correlation of 10 Asian countries from 1980 to 2002. Our conclusion is that the saving–investment correlation in East Asia steadily decreases over time but is still higher than that of the OECD countries over all studied periods. These results are consistent with the fact that capital mobility in East Asia is lower than that in the OECD countries. In addition, regional saving and investment data demonstrate that investment in East Asia is largely financed by regional savings.     

The Role of Property Rights in the Relationship between Capital Flows and Economic Growth in SSA: Do Natural Resources Endowment and Country Income Level Matter?

This paper studies the role played by the quality of property rights in the linkages of international capital flows into sub‐Saharan African (SSA) economies. Using panel data of 36 SSA countries over the period 1996–2015 and the ARDL procedure with the Pooled Mean Group regression method appropriate for non‐stationary panel data estimation, we account for the joint effects of property rights quality and openness to foreign capital flows on economic growth. We uncover the existence of a property rights quality threshold beyond which property rights either amplifies the spillovers effects or attenuates the negative effect of capital flows on economic growth. For instance, it takes a level of property rights of at least 60 to have a positive long‐term impact of capital flows on economic growth in natural resource‐poor African countries. The quality of property rights matters more to obtain spillover effects of capital flows on growth in natural resource‐poor countries than in their peer natural resource‐rich countries. Finally, with regard to the countries' income levels, capital flows have significant long‐term spillovers effects on economic growth in advanced African economies than in their low‐income peers.     

Out-migration and economic cycles

Out-migration concerns foreigners who decide to leave a country where they used to live. Taking advantage of the OECD bilateral IMS database, we analyze the short-run determinants of out-migration using a panel of Schengen countries between 1995 and 2011. We find that out-migration is counter-cyclical: foreign nationals tend to leave host countries with high unemployment, while they are likelier to stay in good times (i.e. low unemployment). Typically, a 10 % increase in the unemployment rate leads to a 5 % increase in out-migration. Thus, short-term economic fluctuations have the same qualitative effect as restrictive migration policies in economic downturns. However, we find mixed evidence for the role of economic cycles in the potential destination countries of those flows. Movers appear to be sensitive to unemployment changes in their country of origin, but they do not seem to be sensitive to business cycles in potential destinations.     

Does Cultural Distance Hinder Trade in Goods? A Comparative Study of Nine OECD Member Nations

We examine the effect of cultural distance, a proxy for the lack of a minimum reservoir of trust necessary to initiate and complete trade deals, on bilateral trade flows. Employing data for 67 countries that span the years 1996–2001, we estimate a series of modified gravity specifications and find that cultural dissimilarity between nations has an economically significant and consistently negative effect on aggregate and disaggregated trade flows; however, estimated effects vary in magnitude and economic significance across measures of trade and our cohort of OECD reference countries. The consistently negative influence of cultural distance indicates that policymakers may wish to consider mechanisms that enhance the build-up of trust and commitment when seeking to facilitate the initiation and completion of international trade deals. Our findings also imply that coefficient estimates from related studies that do not account for the trade-inhibiting effect of cultural distance may be biased.     

Temporary Migration and Foreign Direct Investment

The question of complementarity or substitutability of FDI and international labour mobility has not yet been answered. The substitutability assumption does not take into consideration the technological spillover of FDI in the host countries. Moreover, migration flows reveal cultural characteristics and labour force properties of their native country which may stimulate bilateral business networks, strengthening the complementarity assumption between capital and labour flows. In this paper we build a continuous time dynamic model where these offsetting forces are at work. We analyze whether, and to what extent, the increase in labour mobility might affect FDI outflows. A numerical simulation is performed showing that a higher income growth rate corresponds to a higher labour mobility. Some policy implications and further research direction are suggested.     

Private capital flows,stock market and economic growth in developed and developing countries: A comparative analysis

Empirically we investigate how three types of private capital flows could promote economic growth in recipient developed and developing countries. Our focus is on the role of stock markets as a channel through which foreign capital flows could promote growth. The findings reveal that FDI exhibits a positive impact on growth, while both foreign debt and portfolio investment have a negative impact on growth in all sample countries. However, our results indicate that stock markets might be a significant channel or leading institutional factor through which capital flows affect economic growth. The findings provide clear implications that the negative impact of private capital flows can be transformed into a positive one if the stock market development has attained a certain threshold level, regardless of whether it is in developed or developing countries.     

How would Capital Account Liberalization Affect China＇s Capital Flows and the Renminbi Real Exchange Rates？

In this paper we study the determinants of gross capital flows, project the size of China's international investment position in 2020, and analyze the implications for the renminbi real exchange rate if China liberalizes the capital account. We assume in this exercise that the renminbi will have largely achieved capital account convertibility by the end of the current decade, a timetable consistent with recent proposals by the People's Bank of China. Our analysis shows that if the capital account were liberalized, China's gross international investment position would grow significantly, and inflows and outflows would become much more balanced. The private sector would turn its net liability position into a balanced position, and the official sector would reduce its net asset position significantly, relative to the country's GDP. Because of the increasing importance of private sector foreign claims and the decreasing importance of official foreign reserves, China would be able to earn higher net investment income from abroad. Overall, China would continue to be a net creditor, with the net foreign asset position as a share of GDP remaining largely stable through this decade. These findings suggest that the renminbi real exchange rate would not be particularly sensitive to capital account liberalization as capital flows are expected to be two‐sided. The renminbi real exchange rate would likely be on a path of moderate appreciation as China is expected to maintain a sizeable growth differential with its trading partners.     

资本流动的衡量标准研究

很多研究者在分析一国资本是流入还是流出以及流量的大小时,通常是根据国际收支平衡表上资本与金融账户的情况加以判断的。本文对该做法提出了异议。本文认为在判断一国资本的流向及流量时,应以实际资本的流动情况为准,本文还考察了金融资本与实际资本流动的一致性程度。     

International Trade, OECD Membership, and Religion

Transaction costs in trade gravity equation are proxied by the distance that separates two trading partners, under the assumption that the distance elasticity is the same across all trading partners. We show that distance elasticity, however, critically depends on whether trading partners are industrial countries (i.e., members of the OECD) or share same religion. These heterogeneities are both statistically and economically significant. For instance, expected trade flows are the largest when an OECD member trades with a non-member and both are non-religious. Expected trade flows fall as much as by 62.9% between two non-religious, non-OECD members. Expected bilateral trade drops by 48.1% when both countries in the pair are OECD members while one is Christian and the other is Islamic. Both religion and OECD membership significantly affect the typical transaction costs implied by the gravity equation. JEL Classification Number: F13     

Convergence in Revealed Preferences for Automobiles as Differentiated Goods: U.S. and OECD Countries: 1970–1999

Attributes of differentiated goods in personal consumption have both conceptual and policy importance in macroeconomic applications that include obsolescence rates of capital stock, the savings rate, and environmental issues. While there is both direct and indirect evidence of variation in preferences for these attributes across countries, there is also conjecture that recent global integration has reduced this variation. We examine convergence between the U.S. and four OECD countries in the levels of automobile attributes over the 1970–1999 period. Results of panel unit root tests with the U.S. as the comparison country showed convergence in the constructed measures of size, performance and efficiency. In pairwise comparisons between the U.S. and OECD countries, results of our model estimations indicated convergence in size and efficiency with estimated half lives to convergence of between four to six years. Disaggregating the definitional components of performance, results show convergence in horsepower when selected economic variables are controlled. We find that measures of trade, per capita income and price appear to be among the mechanisms through which increasing global integration relates to convergence. Directions for further study of convergence preferences for attribute profiles across countries are discussed.     

Freedom and International Migration

Economic and political freedoms are regressed on a bilateral cross section of international migrant stocks using ordinary least squares and Tobit techniques. A positive relationship between these variables is found. Economic freedom is statistically significant even when controlling for income per capita and political freedom. In addition, the impact of these freedoms on migration flows into OECD countries between 2001 and 2006 using fixed effects estimations is analyzed. The panel data analysis mostly corroborates the cross‐sectional analysis. The notable exception is that political freedom appears to have had a negative impact on migration flows during this period.     

Export subsidies and minimum access guarantees in agricultural trade: a developing country perspective

The paper presents a framework for and results from a quantitative analysis of two proposals to GATT, made as part of an effort at containing or rolling back the spread of non-tariff barriers in agriculture. The first proposes export subsidies, which would be financed by the producers themselves, requiring no government outlay. The second calls for a minimum access for importers. This analysis examines the magnitude of the effects on trade flows, world prices, the impact on the production, consumption, and trade of the OECD countries and on foreign exchange earnings of less developed countries (LDCs), of minimum access as applied to sugar trade — one of the most protected products in OECD countries and one with great potential for LDC exporters. Results are then compared with an analysis of more comprehensive trade liberalization in the sugar market, i.e., complete removal of trade barriers in all OECD countries.     

Convergence,the “tax-state” and economic dynamics

Convergence, the “Tax State” and Economic Dynamics. — The paper analyses the welfare/efficiency relationship of taxation and empirically tests the relationship between taxes and economic dynamics for OECD countries. Since taxes are only one of the determinants of economic growth, in a first step the influence of other sources of or impediments to economic growth is analysed. This general model - which contains hypotheses about catching-up, the technological gap, human capital and inflation - is tested against a specific model in which the specific interest is in the role of taxes. For the group of the most important OECD countries taxation turns out to be growth-retarding.     

Novel indicators of the trade and welfare effects of agricultural distortions in OECD countries

Agricultural markets in OECD countries have long been highly distorted by government policies. Traditional weighted average aggregates of the price distortions involved, such as producer and consumer support estimates (PSEs and CSEs), can be poor indicators of the trade restrictiveness and economic welfare losses associated with them, especially if a country’s support estimates vary a lot across the product range. Certainly estimates of trade and welfare effects of price supports can be obtained from sectoral or economywide models using price elasticity estimates, but the results can be contentious if there is no consensus on what model specification and elasticity parameters to use. This paper shows that, if there is a willingness to accept simple assumptions about elasticities, it is possible to generate indicators of the welfare and trade restrictiveness of agricultural policies using no more than the price and quantity data needed to generate PSEs and CSEs. These new indexes thus provide an attractive supplement to the current policy monitoring regime developed by the OECD Secretariat.
