Macroeconomics In Times Of Liquidity Crises

An examination of Liquidity Crunch in triggering and characterizing financial crises. Since the subprime mortgage crisis that began in 2007, advanced economies have felt a nagging sense of insecurity. In parallel, the profession has witnessed phenomena that are alien to mainstream macroeconomic models. Financial crises are systemic, occurring simultaneously in different economies. In this book, Guillermo Calvo focuses on liquidity factors as a commonality in financial crises. Specifically, he examines the role of “liquidity crunch” in triggering crises. He also identifies a fundamental (but overlooked) idea in Keynes's General Theory, termed by Calvo the price theory of money, to rationalize the resiliency of the U.S. dollar when other dollar-backed assets suffered a devastating liquidity crunch. Calvo shows that a sharp focus on liquidity reveals some characteristics of liquid assets that are easy to miss otherwise. He argues for liquidity's centrality, presenting what he calls the Liquidity Approach. He shows that simple extensions of standard monetary models help rationalize the implications of the liquidity crunch, and then examines slightly more technical models that highlight liquidity issues. He explores the empirical effects of liquidity crunch by studying systemic sudden stops (of capital inflows), presuming that they are triggered by liquidity crunch-type phenomena.

Financial crises have been pervasive for many years. Their frequency in recent decades has been double that of the Bretton Woods Period (1945-1971) and the Gold Standard Era (1880-1993), comparable only to the period during the Great Depression. Nevertheless, the financial crisis that started in the summer of 2007 came as a great surprise to most people. What initially was seen as difficulties in the U.S. subprime mortgage market, rapidly escalated and spilled over first to financial markets and then to the real economy. The crisis changed the financial landscape worldwide and its full costs are yet to be evaluated. One important reason for the global impact of the 2007-2009 financial crisis was massive illiquidity in combination with an extreme exposure of many financial institutions to liquidity needs and market conditions. As a consequence, many financial instruments could not be traded anymore, investors ran on a variety of financial institutions particularly in wholesale markets, financial institutions and industrial firms started to sell assets at fire sale prices to raise cash, and central banks all over the world injected huge amounts of liquidity into financial systems. But what is liquidity and why is it so important for firms and financial institutions to command enough liquidity? This book brings together classic articles and recent contributions to this important field of research. It provides comprehensive coverage of the role of liquidity in financial crises and is divided into five parts: (i) liquidity and interbank markets; (ii) the public provision of liquidity and regulation; (iii) money, liquidity and asset prices; (iv) contagion effects; (v) financial crises and currency crises.

We study whether capital flows affect the degree of credit crunch faced by a country's manufacturing firms during the 2007-09 crisis. Examining 3823 firms in 24 emerging countries, we find that the decline in stock prices was more severe for firms that are intrinsically more dependent on external finance for working capital. The volume of capital flows has no significant effect on the severity of the credit crunch. However, the composition of capital flows matters: pre-crisis exposure to non-FDI capital inflows worsens the credit crunch, while exposure to FDI alleviates the liquidity constraint. Similar results also hold surrounding the Lehman Brothers bankruptcy

Shows how the Keynesian approach to business cycles can be used to explain and understand the current financial crisis.

This paper reviews the literature on financial crises focusing on three specific aspects. First, what are the main factors explaining financial crises? Since many theories on the sources of financial crises highlight the importance of sharp fluctuations in asset and credit markets, the paper briefly reviews theoretical and empirical studies on developments in these markets around financial crises. Second, what are the major types of financial crises? The paper focuses on the main theoretical and empirical explanations of four types of financial crises—currency crises, sudden stops, debt crises, and banking crises—and presents a survey of the literature that attempts to identify these episodes. Third, what are the real and financial sector implications of crises? The paper briefly reviews the short- and medium-run implications of crises for the real economy and financial sector. It concludes with a summary of the main lessons from the literature and future research directions.

We build a model of financial sector illiquidity in an open economy. Illiquidity defined as a situation in which a country's consolidated financial system has potential short-term obligations in foreign currency that exceed the amount of foreign currency it can have access to on short notice can be associated with self fulfilling bank and/or currency crises. We focus on the policy implications of the model, and study the role of capital inflows and the maturity of external debt, the way in which real exchange rate depreciation can transmit and magnify the effects of bank illiquidity, options for financial regulation, the role of debt and deficits, and the implications of adopting different exchange rate regimes.

This book collects selected articles addressing several currently debated issues in the field of international macroeconomics. They focus on the role of the central banks in the debate on how to come to terms with the long-term decline in productivity growth, insufficient aggregate demand, high economic uncertainty and growing inequalities following the global financial crisis. Central banks are of considerable importance in this debate since understanding the sluggishness of the recovery process as well as its implications for the natural interest rate are key to assessing output gaps and the monetary policy stance. The authors argue that a more dynamic domestic and external aggregate demand helps to raise the inflation rate, easing the constraint deriving from the zero lower bound and allowing monetary policy to depart from its current ultra-accommodative position. Beyond macroeconomic factors, the book also discusses a supportive financial environment as a precondition for the rebound of global economic activity, stressing that understanding capital flows is a prerequisite for economic-policy decisions.
