Malignant hypertension still constitutes a medical emergency, particularly when complicated by renal failure, encephalopathy, or left ventricular failure. A shift to the right of the autoregulatory curve of cerebral blood flow (and probably of renal blood flow) is known to occur in patients with hypertension. Local cerebral edema, complicating the malignant phase, is likely to aggravate this tr...

Over the past two decades, financial market crises with similar features have occurred in different regions of the world. Unstable cross-market linkages during financial crises are referred to as financial contagion. We simulate the transmission of financial crises in the context of a model of market participants adopting various strategies; this allows testing for financial contagion under alt...

The world economy is entering an era of multiple crises, involving finance, food security and global environmental change. This article assesses the implications for global public health, describes the contours of post-2007 crises in food security and finance, and then briefly indicates the probable health impacts. There follows a discussion of the crisis of climate change, one that will unfold...

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...

This chapter surveys the literature on bubbles, financial crises, and systemic risk. The first part of the chapter provides a brief historical account of bubbles and financial crisis. The second part of the chapter gives a structured overview of the literature on financial bubbles. The third part of the chapter discusses the literatures on financial crises and systemic risk, with particular emp...

Crises are frequent and varied, and may have profound effects on individuals and organizations. Effectively managing crises, regardless of their scope, requires the ability to quickly process potentially large amounts of information about a rapidly changing world. This paper presents a software architecture, the event web, that can be used to help effectively manage crises. An event web allows ...

The financial liberalization in the four Nordic countries (Denmark, Finland, Norway, and Sweden) that took place mostly in the 1980s led to a major financial crisis in three of those countries. The crises in Finland, Norway, and Sweden are among the deepest financial crises in advanced market economies since World War II. Denmark experienced some banking problems but managed to avoid a systemic...

I describe two amplifications mechanisms that operate during liquidity crises and discuss the scope for central bank policies during crises as well as preventive policies in advance of crises. The first mechanism works through asset prices and balance sheets. A negative shock to the balance sheets of asset-holders causes them to liquidate assets, lowering prices, further deteriorating balance s...

The issue Economic crises bring to the fore deep issues for the economic profession: why are such crises often not foreseen, and what does this entail for economic theory? In this symposium we also adopt a self-critical analysis, by asking the following: what can the cognitive science community say or learn about cognition and behavior in the context of economic crises? After all, cognitive sci...
