This paper considers the role of monetary policy in mitigating the effects of financial crises. I suppose that the economy occasionally but infrequently experiences crises, where financial variables directly affect the broader real economy. I analyze the formulation of monetary policy under such financial uncertainty, where policymakers recognize the possibility of financial crises, which leads...

Sudden stops can be characterized by sharp reversals in capital inflows, large declines in output, and steep collapses in real asset prices (Mendoza and Smith, 2009). In almost all recent crises, capital account reversals amounting to more than 10% of an afflicted country’s GDP have occurred (Calvo and Reinhart, 1999 and Nabli, 1999). More specifically, reversals in capital flows to emergin...

We study optimal macroprudential policy in a model in which unconventional shocks, in the form of news about future fundamentals and regime changes in world interest rates, interact with collateral constraints in driving the dynamics of financial crises. These shocks strengthen incentives to borrow in good times (i.e. when “good news” about future fundamentals coincide with a low-world-interest...

We investigate the impact of financial crises on two fundamental features of stock returns, namely, the risk-return tradeoff and the leverage effect. We apply the fractionally integrated exponential GARCH-in-mean (FIEGARCH-M) model for daily stock return data, which includes both features and allows the co-existence of long memory in volatility and short memory in returns. We extend this model ...

The magnitude and frequency of recent financial crises underscore the importance of understanding financial instability for the purpose of crisis prevention and crisis management. This paper brings together and adds structure to the theoretical literature on financial instability and the implications they carry for policy-makers. In addition to clarifying the theoretical underpinnings for study...

We examine the impact of corporate currency hedging on economic stability by introducing hedging activity in a Mundell-Fleming-Tobin framework for analyzing currency and financial crises. The ratio between hedged and unhedged firms is modelled depending on firm size as well as hedging costs. The results indicate that, with an increasing fraction of hedged firms in an economy, the magnitude of a...

As the current crisis has painfully proved, the financial system plays a crucial role in economic development. Although the current crisis is being of an exceptional magnitude, financial crises are recurrent phenomena in modern financial systems. The literature offers several definitions of financial instability, but for our purposes we identity financial crisis with banking crisis as the most ...

Since 2008, Western countries are going through a deep economic crisis whose health impacts seem to be fundamentally counter-cyclical: when economic conditions worsen, so does health, and mortality tends to rise. While a growing number of studies have presented evidence on the effect of crises on the average population health, a largely neglected aspect of research is the impact of crises and t...

Abstract. Major mass extinctions in the Phanerozoic Eon occurred during abrupt global climate changes accompanied by environmental destruction driven large volcanic eruptions and projectile impacts. Relationships between land temperature anomalies terrestrial animal extinctions, as well difference response marine animals to Phanerozoic, have not been quantitatively evaluated. My analyses show t...
