International capital flows and convergence in the neoclassical growth model

To analyze how capital mobility affects economic growth and convergence, this paper will use the analytical solution to the neoclassical growth model with a constant saving rate, beginning with the closed-economy Solow growth model. An introduction to international capital flows will follow. In an open economy, free capital mobility assures an instantaneous convergence in interest rates that, under a perfect competence situation, implies the instantaneous convergence in income levels among homogeneous countries. Taking into account this question and to reconcile these results with empirical evidence, that is, with the gradual convergence observed, the assumption is introduced that in spite of free capital mobility, there are international credit restrictions. In this case, we will show how the rate of convergence depends on the international capital inflows received.

Human capital distribution, growth and convergence

This paper studies the dynamic relationship between distribution and endogenous growth in an overlapping generations model with accumulation of human and physical capital. It is shown how human capital can determine a relationship between per capita growth rates and inequality in the distribution of income. Family background effects and spillovers in the transmission of human capital generate dynamics in which aggregate variables depend not only on the stock, but also on the distribution of human capital. The evolution of this distribution over time is then characterized under different assumptions on private returns and the form of the externality in the technology for human capital. Conditions for existence, uniqueness and stability of a constant growth equilibrium with a stationary distribution are derived. Increasing returns, idiosyncratic abilities and the possibility of poverty traps are explicitely characterized in a closed form solution of the equilibrium dynamics, showing the role played by technology and preferences parameters.     

Beyond Balassa–Samuelson: Real appreciation in tradables in transition countries1

We decompose real appreciation in tradables derived from producer price indexes in three Central European countries between the pricing‐to‐market component (disparity) and the local relative price component (the substitution ratio). Appreciation is only partially explained by local relative prices. The rest is absorbed by disparity, depending on the size of the no‐arbitrage band. The observed disparity fluctuates in a wider band for differentiated products than for commodity like goods.     

Bubbles and capital flows

This paper presents a stylized model of international trade and asset price bubbles. Its central insight is that bubbles tend to appear and expand in countries where productivity is low relative to the rest of the world. These bubbles absorb local savings, eliminating inefficient investments and liberating resources that are in part used to invest in high-productivity countries. Through this channel, bubbles act as a substitute for international capital flows, improving the international allocation of investment and reducing rate-of-return differentials across countries. This view of asset price bubbles could eventually provide a simple account of some real world phenomena that have been difficult to model before, such as the recurrence and depth of financial crises or their puzzling tendency to propagate across countries.     

Financial integration, capital mobility, and income convergence

Recent studies have found that capital moves 'uphill' from poor to rich countries, and brings little or no growth dividend when it does flow into poor economies. We show that Europe does not conform to this paradigm. In the European experience of financial integration, capital has flown from rich to poor countries, and such inflows have been associated with significant acceleration of income convergence. Analysing broader samples of countries, we find that 'downhill' capital flows tend to be observed above certain thresholds in institutional quality and financial integration. But Europe remains different even when allowing for such threshold effects, and its experience is similar to that of interstate flows within the United States. Our findings are consistent with the notion that financial diversification reduces countries' incentives to save in order to self-insure against specific shocks.

Trade and Personal Distribution of Wealth and Income: Beyond the Stolper–Samuelson Theorem

The effect of international trade on personal distribution of wealth and income is examined via the Stolper–Samuelson Theorem. It is shown that free trade between North and South increases (decreases) wealth and income inequality in the North (South). A concept of three classes – lower, middle and upper – is developed. It is shown that North–South free trade in goods leads to a middle class squeeze in the North and a middle class expansion in the South.     

COVID-19, asset markets and capital flows

This paper empirically examines the reaction of global financial markets across 38 economies to the COVID-19 outbreak, with special focus on the dynamics of capital flows across 14 emerging market economies. The effectiveness of fiscal and monetary policy responses to COVID-19 is also tested. Using daily data over the period January 4, 2010 to August 31, 2020, and controlling for a host of domestic and global macroeconomic and financial factors, we use a fixed effects panel approach and a structural VAR framework to show that emerging markets have been more heavily affected than advanced economies. In particular, emerging economies in Asia and Europe have experienced the sharpest impacts on stock, bond and exchange rates due to COVID-19, as well as abrupt and substantial capital outflows. Quantitative easing and fiscal stimulus packages mainly helped to boost stock prices, notably for advanced and emerging economies in Asia. Our findings also highlight the role that global factors and developments in the world's leading financial centers have on financial conditions in EMEs. Importantly, the impact of COVID-19 related quantitative easing measures by central banks in advanced countries extended to EMEs, with significant positive spillovers to EME stock markets in Asia, Europe and Latin America. Going forward, while the ultimate resolution of COVID-19 may be expected to lead to a market correction as uncertainty declines, our impulse response analysis suggests that there may be persistent effects on bond markets in emerging Europe and on EME capital flows.     

European integration, productivity growth and real convergence

This paper derives a stochastic endogenous growth model to investigate the impact of European Union (EU) integration on convergence and productivity growth. The theoretical model implies both temporary and permanent positive effects of the integration process. The empirical part of the analysis uses structural break tests and data envelopment analysis to examine the accession process of five recent members to the EU15. The results show (i) endogenously identified accession dates as structural breaks, (ii) improved rates of productivity growth after accession over and above the Union benchmark level, and (iii) increased pace of overall growth due to capital accumulation as a result of institutional features of the Union such as Structural and Cohesion Funds. These findings support the theoretical model, implying that economic integration is beneficial for member countries, especially from a long-run perspective, and Cohesion and Structural funds help the new members catch up with the core-EU members’ standard of living.     

Fundamentals, information, and international capital flows: A welfare analysis

In the recent discussion surrounding the design of a new international financial architecture, enhancing transparency has widely been proposed as a policy essential for increasing the efficiency of international capital markets. This paper uses a simple two-country (two-agent) general equilibrium model with incomplete markets and production to explore the welfare consequences of an increase in public information about country-specific fundamentals (increase in transparency). An improvement in the quality of information has two effects on the ex ante welfare of individual countries: A direct effect that increases the efficiency of global capital allocation and welfare, and an indirect general equilibrium effect that increases asset price volatility and may decrease welfare. When the degree of risk-aversion is low, at least one country will gain from an increase in information quality. If the degree of risk-aversion is high, then there are robust examples of economies for which an increase in information hurts all countries. The paper also discusses how certain institutional arrangements (international derivative markets, international agency) could ensure that all countries gain from better information by providing insurance against information-induced asset price risk.     

Managerial ability and capital flows

Capital flows with low intensity and flows to middle-income countries. Physical and human capital alone cannot explain this pattern. I present a model to show how managerial ability—the ability to run risky projects—can increase total factor productivity and explain the pattern of capital flows. The model implies that countries with more high-ability managers use more risky projects and have higher productivity. I define proxies for managerial ability with data on physical and human capital, schooling, and entrepreneurship. Consistent with the pattern of capital flows, the model predicts similar returns to capital across countries and higher returns in middle-income countries.     

Intermediation costs and capital flows

In this paper, we modify the standard neoclassical model by incorporating financial intermediation in order to deliver returns consistent with the observation that capital primarily flows to middle income countries. We build a static contracting framework where costly intermediation together with an adverse selection problem have quantitatively important effects on capital flows. When intermediation costs are ignored, the model behaves like the neoclassical model in terms of capital returns. However, when intermediation costs are considered, returns to capital in middle income countries could exceed those in poor and rich countries—high costs of intermediation cause poor countries to concentrate their investments in projects with low returns, while the standard neoclassical effect lowers returns in capital-rich countries. When we embed the return function from the static analysis in a two-country dynamic model, there is capital outflow from a poor country that removes capital controls and becomes open. Even though the closed economy dominates in terms of capital employed in production, it is the open economy that dominates in terms of income, consumption and welfare.     

International capital flows,liquidity risk,and monetary policy

In recent years, there has been a large amount of lending coming from the public sector of many developing countries. At the same time, the financial sectors in many advanced countries have issued a large share of portfolio debt to other countries. What are the implications of these events for the global financial system and overall economic activity? Do they have an impact on the transmission channels of monetary policy across countries at different stages of economic development? We investigate these important issues using a micro-founded model of money and banking so that the effects of monetary policy across countries can be meaningfully studied. Notably, the increase in capital outflows to the advanced economy renders monetary policy in developing countries to be less effective, while the effects of monetary policy in advanced economies are more pronounced. Yet, our results indicate that it can indeed be optimal for lower income countries to lend to the advanced world. Importantly, we find that the optimal amount of lending to advanced countries critically depends on the degree of liquidity risk — if it is sufficiently high, then public sector lending to advanced economies is not warranted. Consequently, our results indicate that governments in developing countries should carefully consider how much capital they send abroad to foreign countries.     

国际资本流动对房地产价格的影响——基于中国的实证检验:1998-2006

Taking the inflation into consideration and making use of the quarter data of the actual foreign investment, housing and land prices in China from 1998 to 2006, this paper examines the relationship between housing prices and international capital flows using Error Correction Model (ECM) and Granger causality test. Results show that in the short run, the increase of housing prices attracts the inflow of foreign capitals; in the long run, foreign capitals help to boost the rise of housing prices. Therefore, at present, Chinese government must impose effective restrictions on the flow of foreign capital into the real estate market. __________ Translated from Caijing Wenti Yanjiu 财经问题研究 (Research on Financial and Economic Issues), 2007, (3): 55–61     

Managing capital flows in Poland, 1995-98

Poland has been encouraging foreign direct investment, including the purchase of company shares, but has been attempting to limit the inflow of speculative short-term capital. The policy so far has been effective without the use of any capital controls. The paper explains the policy and the reasons for its apparent success. The paper also discusses the evolving threats to macroeconomic stability of the Polish economy and policy responses to these threats.     

Intersectoral capital flows: Evidence from Kenya

Evidence is presented for a large net capital outflow from the agricultural sector in Kenya between 1964 and 1972, increasing over the period. The financial and structural shifts underlying this flow are examined and interpreted. Because of the fragmented financial system in Kenya, most of the funds were not mobilized in a form readily available for re-investment in agriculture or elsewhere in the economy.     

Capital flows,real exchange rate,and growth constraints in Mexico

Besides its well‐known problem of slow economic growth, Mexico’s recent evolution features both a sharp rise in the import‐intensity of economic activity – which may have tightened an external constraint on growth – and a persistent real appreciation of the peso – which may have created a profitability constraint. Adopting the approach of gap models and growth diagnostics, the paper contrasts the relevance of the external and the profitability constraints in Mexico after trade liberalization in the mid‐1980s. Although the trade deficit was pro‐cyclical, the three recent episodes of GDP growth acceleration were not accompanied by pressures in the foreign exchange market. Moreover, error correction models show that investment was highly responsive to the real exchange rate but largely unresponsive to foreign capital flows. The evidence supports the conclusion that investment was deterred by the low profitability of an uncompetitive real exchange rate, rather than by the external constraint.     

Unconventional monetary policy and capital flows

This paper examines the connection between the stance of domestic monetary policy and international capital flows. It first provides a simple theoretical framework describing the mechanisms behind the cross-border spillovers of domestic monetary policy. Then, it empirically investigates the impact of U.S. unconventional monetary policies (UMPs), implemented in the aftermath of the recent global financial crisis, on U.S. capital flows to developing economies and non-UMP advanced economies. The results suggest that the use of quantitative easing by the Federal Reserve has been associated with increased net portfolio flows to developing countries and, to a lesser extent, non-UMP advanced economies. An exit from these UMPs is likely to cause capital flow reversals in U.S. capital-importing countries. Countries with greater exchange rate flexibility, stronger fiscal and current account positions, and higher capital mobility are likely to fare well following an exit from UMPs in the U.S.     

Money, capital, and real liquidity effects with habit formation

Abstract.  The money in utility model is reconsidered in the presence of endogenous labour and habits. With standard assumptions about preferences and a policy rule that sets the nominal interest rate by adjusting the growth rate of money, the model exhibits superneutrality in the steady state. Nevertheless, habits give rise to real liquidity effects in the short run. After an increase in the nominal interest rate, employment falls, resulting in a fall in capital accumulation and in the short‐ and long‐term real interest rates. The adjustment of the capital stock is non‐monotonic. Employment and the short‐ and long‐term real interest rates may also adjust non‐monotonically. JEL classification: E22, E52, E58
