This paper analyses financial crises from a theoretical point of view. For this it reviews what different schools of economic thought have to say about financial crises. It examines first the approaches that regard financial crises as a disturbing factor of a generally stable real economy...

In late 1997, Korea experienced a huge and unusual economic crisis. The three main features of this crisis are the sudden recession, the rapid recovery and a consumption drop as large as the output drop. A large body of literature qualitatively explains the Korean crisis in terms of financial...

This paper will discuss how the Financial Crisis of 2008 has thrown neoliberalism into a deep legitimation crisis. Over the past four decades the neoliberal ethic of Ronald Reagan and Margaret Thatcher has permeated American life both public and private. The principles of the laissez faire...

Why do advanced economies fall into prolonged periods of economic stagnation, particularly in the aftermath of credit booms? We present a model of persistent aggregate demand shortage based on strong liquidity preferences of households, in which we incorporate financial imperfections to study...

Since the Global Financial Crisis, academic economists and policymakers have had to deal with uncomfortable questions about the quality of their models and the state of macroeconomics as a profession. This note offers a summary of this discussion, focusing on the Dynamic Stochastic General...

This chapter is on quantitative models of sovereign debt crises in emerging economies. We interpret debt crises broadly to cover all of the major problems a country can experience while trying to issue new debt, including default, sharp increases in the spread and failed auctions.

The DSGE models are based on hypotheses that have the effect of excluding the possibility of severe financial and economic crises with the consequent policy implications going in the laissez-faire direction. The hypothesized unique and stable equilibrium in combination with rational expectations...

Orthodox and heterodox theories of financial crises are hereby compared from a theoretical viewpoint, with emphasis on their genesis. The former view (represented by the fourth generation models of Paul Krugman) reflects the neoclassical vision whereby turbulence is an exception; the latter...
