Stock market synchronization and monetary integration

This paper focuses on the relationship between stock market comovements and monetary integration. A panel specification is used to explain bilateral stock market return correlations between fifteen developed economies over the period 1975-2006. Time fixed effects are included to capture global shocks and we also examine the role of bilateral trade linkages and international financial integration. Monetary integration leads to stronger stock market synchronization, both through the elimination of exchange rate volatility and through the common monetary policy and the convergence of inflation expectations. Trade and financial integration also contribute to higher stock market return comovements.     

The impact of exchange rate deviations from relative PPP equilibrium on the U.S. demand for foreign equities

Applying fixed-effects panel data, this study investigates the impact of U.S. dollar exchange rate movements during different exchange rate states (overvaluation and undervaluation) on the monthly real gross and real net purchases of foreign equities by U.S. residents over the post-Plaza Accord period. The foreign equities come from 22 developed and 25 developing countries. Previous research has posited two alternative hypotheses regarding the relationship between exchange rates and foreign investment. These are the wealth effect and the profit-oriented effect. The evidence herein suggests that these two hypotheses coexist. We find robust evidence for a negative relationship between the exchange rate movements of an undervalued U.S. dollar and the demand for foreign equities. For developed countries, the wealth effect dominates the profit-oriented effect when the U.S. dollar is overvalued, while, for developing countries, the profit-oriented effect dominates the wealth effect. The results emphasize the importance of considering exchange rate states derived from a relative PPP equilibrium when analyzing U.S. allocations to foreign equities. The findings with respect to the macroeconomic control variables are mainly in agreement with the predictions of international financial theory. Some of the results, however, disappear or become inconclusive for the period after the bankruptcy of Lehman Brothers. This may be explained by the increased uncertainty in international financial markets following this unprecedented event. The findings are robust with respect to different constructed equilibrium exchange rates.     

Consumption, (dis)aggregate wealth,and asset returns

In this work, I show, from the consumer's budget constraint, that the residuals of the trend relationship among consumption, financial wealth, housing wealth and labor income (summarized by the variable cday) should predict better U.S. and U.K. quarterly stock market returns than a variable like cay from Lettau and Ludvigson (2001), which considers aggregate wealth instead.I find that the superior forecasting power of cday is due to: (i) its ability to track the changes in the composition of asset wealth; and (ii) the faster rate of convergence of the coefficients to the “long-run equilibrium” parameters.In addition, the results suggest that, while financial wealth shocks are mainly transitory, fluctuations in housing wealth are very persistent. Moreover, they highlight that expectations about future returns are “synchronized” across countries.     

Financial development and the instability of open economies

This paper introduces a framework for analyzing the role of financial factors as a source of instability in small open economies. Our basic model is a dynamic open economy model with a tradeable good produced with capital and a country-specific factor. We also assume that firms face credit constraints, with the constraint being tighter at a lower level of financial development. A basic implication of this model is that economies at an intermediate level of financial development are more unstable than either very developed or very underdeveloped economies. This is true both in the sense that temporary shocks have large and persistent effects and also in the sense that these economies can exhibit cycles. Thus, countries that are going through a phase of financial development may become more unstable in the short run. Similarly, full capital account liberalization may destabilize the economy in economies at an intermediate level of financial development: phases of growth with capital inflows are followed by collapse with capital outflows. On the other hand, foreign direct investment does not destabilize.     

Monetary Policy and Stock Prices in an Open Economy

This paper studies monetary policy in a two-country model where agents can invest their wealth in both stock and bond markets. In our economy the foreign country hosts the only active equity market where also residents of the home country can trade stocks of listed foreign firms. We show that, in order to achieve price stability, the Central Banks in both countries should grant a dedicated response to movements in stock prices driven by relative productivity shocks. Determinacy of rational expectations equilibria and approximation of the Wicksellian interest rate policy by simple monetary policy rules are also investigated.     

Does the ECB act as a lender of last resort during the subprime lending crisis?: Evidence from monetary policy reaction models

We investigate whether the ECB aligns its monetary policy with financial crisis risk in EMU member countries. We find that since the outbreak of the subprime crisis the ECB has significantly increased net lending and reduced interest rates when banking and sovereign debt crisis risk in vulnerable EMU countries (Greece, Ireland, Italy, Portugal, and Spain) increases, while no significant effect is identified for the pre-crisis period and relatively tranquil EMU countries (Austria, Belgium, France, Germany, and the Netherlands). These findings suggest that the ECB acts as a Lender of Last Resort for vulnerable EMU countries.     

Asset Prices,News Shocks,and the Trade Balance

We analyze the relationship between asset prices and the trade balance estimating a Bayesian VAR for a broad set of 38 industrialized and emerging market countries. To derive model‐based identifying restrictions, we model asset price shocks as news shocks about future productivity in a two‐country dynamic stochastic general equilibrium model. Such shocks are found to exert sizable effects on the trade balance. Moreover, the effects are highly heterogeneous across countries. For instance, following a news shock that implies on impact a 10% increase in domestic equity prices relative to the rest of the world, the U.S. trade balance will worsen by up to 1.0 percentage points, but much less so for most other economies. We find that this heterogeneity appears to be linked to the financial market depth and equity home bias of countries. Moreover, the channels via wealth effects and via the real exchange rate are important for understanding the heterogeneity in the transmission.     

Capital inflows and asset prices: Evidence from emerging Asia

The withdrawal of foreign capital from emerging countries at the height of the recent financial crisis and its quick return sparked a debate about the impact of capital flow surges on asset markets. This paper addresses the response of property prices to an inflow of foreign capital. For that purpose we estimate a panel VAR on a set of Asian emerging market economies, for which the waves of inflows were particularly pronounced, and identify capital inflow shocks based on sign restrictions. Our results suggest that capital inflow shocks have a significant effect on the appreciation of house prices and equity prices. Capital inflow shocks account for – roughly – twice the portion of overall house price changes they explain in OECD countries. We also address cross-country differences in the house price responses to shocks, which are most likely due to differences in the monetary policy response to capital inflows.     

Exchange market pressure and absorption by international reserves: Emerging markets and fear of reserve loss during the 2008–2009 crisis

This paper evaluates how the global financial crisis emanating from the U.S. was transmitted to emerging markets. Our focus is on the extent that the crisis caused external market pressures (EMP), and whether the absorption of the shock was mainly through exchange rate depreciation or the loss of international reserves. Controlling for variety of factors associated with EMP, we find clear evidence that emerging markets with higher total foreign liabilities, including short- and long-term debt, equities, FDI and derivative products—had greater exposure and were much more vulnerable to the financial crisis. Countries with large balance sheet exposure – high external portfolio liabilities exceeding international reserves—absorbed the global shock by allowing greater exchange rate depreciation and comparatively less reserve loss. Despite the remarkable buildup of international reserves by emerging markets during the period prior to the financial crisis, countries relied primarily on exchange rate deprecation rather than reserve loss to absorb most of the exchange market pressure shock. This could reflect a deliberate choice (“fear of reserve loss”) or market actions that caused very rapid exchange rate adjustment, especially in emerging markets with open capital markets, overwhelming policy actions.     

Consumption, Aggregate Wealth, and Expected Stock Returns

This paper studies the role of fluctuations in the aggregate consumption–wealth ratio for predicting stock returns. Using U.S. quarterly stock market data, we find that these fluctuations in the consumption–wealth ratio are strong predictors of both real stock returns and excess returns over a Treasury bill rate. We also find that this variable is a better forecaster of future returns at short and intermediate horizons than is the dividend yield, the dividend payout ratio, and several other popular forecasting variables. Why should the consumption–wealth ratio forecast asset returns? We show that a wide class of optimal models of consumer behavior imply that the log consumption–aggregate wealth (human capital plus asset holdings) ratio summarizes expected returns on aggregate wealth, or the market portfolio. Although this ratio is not observable, we provide assumptions under which its important predictive components for future asset returns may be expressed in terms of observable variables, namely in terms of consumption, asset holdings and labor income. The framework implies that these variables are cointegrated, and that deviations from this shared trend summarize agents' expectations of future returns on the market portfolio.     

Regime Change and the Role of International Markets on the Stock Returns of Small Open Economies

We examine the influence of US, UK and German macroeconomic and financial variables on the stock returns of two relatively small, open European economies, Ireland and Denmark. Within a nonlinear framework, we allow for time variation via regime switching using a smooth transition regression (STR) model. We find that US (global) and UK and German (regional) stock returns are significant determinants of returns in both markets. Further, global information represented by oil and US asset price movements drive changes between states in each market. Significantly, the role of country‐specific domestic variables is typically confined to a single state while global and regional variables pervade all states.     

Stock market liberalization and innovation

We investigate the effect of stock market liberalization on technological innovation. Using a sample of 20 economies that experience stock market liberalization, we find that these economies exhibit a higher level of innovation output after liberalization and that this effect is disproportionately stronger in more innovative industries. The relaxation of financial constraints, enhanced risk sharing between domestic and foreign investors, and improved corporate governance are three plausible channels that allow stock market liberalization to promote innovation. Finally, we show that technological innovation is a mechanism through which stock market liberalization affects productivity growth and therefore economic growth. Our paper provides new insights into the real effects of stock market liberalization on productivity growth and the economy.     

Prestigious stock exchanges: A network analysis of international financial centers

In this paper, we use methods from social network analysis to assess the relative importance of financial centers around the world. Using data from virtually the entire universe of global equity activity, we present complete rankings for 45 separate locations for the period 1990–2006. Our analysis constructs a network measure of prestige based on their ability to attract global IPOs. U.S. exchanges are effectively the unique hosts for cross-border equity activity from many other locations. Moreover, they are the destination of choice for most companies coming from locations with highly prestigious exchanges. We also document the emergence of several competing stock exchanges from developed and emerging market economies. The ascent of these stock markets, however, might reflect improved conditions in a growing global market rather than a decline in the competitiveness of U.S. exchanges.     

Stock market liberalization and operating performance at the firm level

I use firm-specific measures of openness to foreign investors to study the impact of stock market liberalization on firm-level operating performance. In a sample of over 1,100 firms from 28 countries, firms with stocks that are open to foreign investors experience higher growth, greater investment, greater profitability, greater efficiency, and lower leverage. Strategies to address potential endogeneity suggest that the observed relation reflects, at least in part, a causal effect of openness on operating performance.     

Sources of Fluctuations in Islamic,U.S., EU,and Asia Equity Markets: The Roles of Economic Uncertainty,Interest Rates,and Stock Indexes

This article analyzes the economic and financial sources of fluctuations among the U.S. federal funds rates, the U.S. economic policy uncertainty, and the indices of the U.S., European, Asian, and Islamic stock markets. The impulse response analysis shows that the U.S. economic policy uncertainty shocks have significant and negative effects unanimously on the U.S., European, Asian, and Islamic stock markets. A contractionary monetary policy shock, in terms of a higher federal funds rate, has also a statistically significant and negative effect on all of the stock markets. The variance decomposition results indicate that the Islamic stock index is mainly affected by the U.S. stock index shock, thus negating its dichotomy hypothesis. The U.S. economic uncertainty shock explains an important portion of fluctuations for all four stock indices. The degree of synchronization between the EU stock market and other markets has weakened after the U.S. financial crisis.     

Monetary policy spillovers and the trilemma in the new normal: Periphery country sensitivity to core country conditions

We investigate why and how the financial conditions of developing and emerging market countries (peripheral countries) can be affected by the movements in the center economies – the U.S., Japan, the Eurozone, and China. We apply a two-step approach. First, we estimate the sensitivity of countries' financial variables to the center economies [policy interest rate, stock market prices, and the real effective exchange rates (REER)] while controlling for global and domestic factors. Next, we examine the association of the estimated sensitivity coefficients with the macroeconomic conditions, policies, real and financial linkages with the center economies, and the level of institutional development. In the last two decades, for most financial variables, the strength of the links with the center economies have been the dominant factor while the movements of policy interest rate also appear sensitive to global financial shocks around the emerging market crises of the late 1990s and since the global financial crisis of 2008. While certain macroeconomic and institutional variables are important, the arrangement of open macropolicies such as the exchange rate regime and financial openness are also found to have direct influence on the sensitivity to the center economies. An economy that pursues greater exchange rate stability and financial openness faces a stronger link with the center economies through policy interest rates and real effective exchange rate (REER) movements. We also find that exchange market pressure (EMP) in peripheral economies is sensitive to the movements of the center economies' REER and EMP during and after the global financial crisis. Open macro policy arrangements, especially exchange rate regimes, also have indirect effects on the strength of financial linkages, interacting with other macroeconomic conditions. Thus, trilemma policy arrangements, including exchange rate flexibility, continue to affect the sensitivity of developing countries to policy changes and shocks in the center economies.     

Contagion in financial markets after September 11: myth or reality?

Major global events can lead to a change in the cross‐country correlation of assets. Using stock prices from 25 economies, we test whether the terrorist attack in the United States on September 11, 2001, resulted in a contagion—an increase in correlation across global financial markets. Unlike prior works on contagion, we model the intrinsic heteroskedasticity. Our results indicate that international stock markets, particularly in Europe, responded more closely to U.S. stock market shocks in the three to six months after the crisis than before. Our evidence suggests that the benefits of international diversification in times of crisis are substantially diminished.     

Foreign Direct Investment and Debt Financing in Emerging Economies

The rich dynamics of capital flows is an important characteristic of business cycles in emerging market economies. In the data external debt is always procyclical, while FDI is procyclical only in normal times. We provide a microfounded rationale for this pattern by linking financial shocks to capital flows. For this purpose, we build a small open economy model in which firms are subject to borrowing constraints, and are either owned domestically or by foreign investors who purchase firms through FDI. During a financial crisis, the valuation gap per unit net worth between foreign and domestic investors widens, which triggers more FDI inflow. Our model produces business cycle moments consistent with empirical observations.     

The open economy consequences of U.S. monetary policy

We consider the open economy consequences of U.S. monetary policy, extending the identification approach of Romer and Romer (2004) and adapting it for use with asset prices. Intended policy changes are orthogonalized against the economy’s expected future path, which captures any effects from open economy variables. Estimated from a set of bilateral VARs, the dynamic responses of the exchange rate, foreign interest rate, and foreign output are consistent with recent work that identifies U.S. policy via futures market changes and a priori impulse response bounds. We compare the two approaches, finding important commonalities. We also outline some advantages of our approach.     

Real Estate Versus Financial Wealth in Consumption

The consumption function for the U.S. economy is estimated with real estate and financial wealth for quarterly data for 1952:1–2001:4. An additional dollar of real estate wealth increases consumption by 8 cents in the current year, as compared with only 2 cents for financial wealth. The results are consistent with theoretical bounds on the marginal propensity to consume from aggregate wealth. The decline in the stock market during 2000–2001 had a limited impact on aggregate demand in part because of an offsetting real estate wealth effect.
