This dissertation focuses on the drivers of international capital flows to emerging markets, as well as the determinants of crises in emerging markets. Particular emphasis is devoted to the role of U.S. monetary policy. The dissertation consists of three independent chapters.
Chapter 1 is a survey of the voluminous empirical literature on the drivers of capital flows to emerging markets. The contribution of the survey is to provide a comprehensive assessment of what we can say with relative confidence about the empirical drivers of EM capital flows. The evidence is structured based on the recognition that the drivers of capital flows vary over time and across different types of capital flows. The drivers are classified using the traditional framework for external and domestic factors (often referred to as “push versus pull” drivers), which is augmented by a distinction between cyclical and structural factors. Push factors are found to matter most for portfolio flows, somewhat less for banking flows, and least for foreign direct investment (FDI). Pull factors matter for all three components, but most for banking flows. A historical perspective suggests that the recent literature may have overemphasized the importance of cyclical factors at the expense of longer-term structural trends.
Chapter 2 undertakes an empirical analysis of the drivers of portfolio flows to emerging markets, focusing on the role of Fed policy. A time series model is estimated to analyze two different concepts of high frequency portfolio flows, including monthly data on flows into investment funds and a novel dataset on monthly portfolio flows obtained from individual national sources. The evidence presented in this chapter suggests a more nuanced interpretation of the role of U.S. monetary policy. In the existing literature, it is traditionally argued that Fed policy tightening is unambiguously negative for capital flows to emerging markets. By contrast, the findings presented in this dissertation suggest that it is the surprise element of monetary policy that affects EM portfolio inflows. A shift in market expectations towards easier future U.S. monetary policy leads to greater foreign portfolio inflows and vice versa. Given current market expectations of sustained increases in the federal funds rate in coming years, EM portfolio flows could be boosted by a slower pace of Fed tightening than currently expected or could be reduced by a faster pace of Fed tightening.
Chapter 3 examines the role of U.S. monetary policy in determining the incidence of emerging market crises. A negative binomial count model and a panel logit model are estimated to analyze the determinants of currency crises, banking crises, and sovereign defaults in a group of 27 emerging economies. The estimation results suggest that the probability of crises is substantially higher (1) when the federal funds rate is above its natural level, (2) during Fed policy tightening cycles, and (3) when market participants are surprised by signals that the Fed will tighten policy faster than previously expected. These findings contrast with the existing literature, which generally views domestic factors as the dominant determinants of emerging market crises. The findings also point to a heightened risk of emerging market crises in the coming years if the Fed continues to tighten monetary policy.
Since the beginning, central banks have used a wide range of instruments to achieve their ultimate purpose of price stability. One measure in the authorities toolbox is a foreign exchange market intervention. The discussion about this instrument has come a long way. So far, the discussion relied mainly on industrialized countries' experiences. The negative outcomes of most studies with respect to the effectiveness of the intervention tool, opened up a discussion, whether interventions should be used by the authorities to manage exchange rate aspects. Consequently, the question about the dynamics of foreign exchange market interventions is now open to the subject-matter of developing and emerging market countries. Monetary policy in those countries often constitutes an active management of exchange rates. However, the basic discussions about intervention dynamics have had one essential drawback. Neither the primary literature of industrialized countries nor studies dealing with developing countries have considered the fact that intervention purposes and the corresponding effects are likely to vary over time. This thesis is designed to provide the reader with essential issues of central bank interventions, and aims to give further, as well as new contributions, in terms of empirical research on interventions in emerging markets. The main objectives of this study are the analysis of central bank intervention motives, and the corresponding effects on exchange rates in emerging markets. The time dependency of both issues is explicitly considered, which states a novelty in academic research of central bank interventions. Additionally, the outcomes are discussed against the background of underlying economic and monetary policy fundamentals. This could well serve as a starting point for further research.
