This paper considers whether there were periodically collapsing rational speculative bubbles in commodity prices over a forty year period from the late 1960s. We apply a switching regression approach to a broad range of commodities using two different measures of fundamental values – estimated...

The author suggests the 2008 financial crisis was the culmination of an accelerating process of financial market evolution that is inherently unstable. From his viewpoint markets are not well organized to manage the power financial assets have to generate emotion and their wider effect on human...

We develop a model of rational bubbles based on leverage and the assumption of an imprecisely known maximum market size. In a bubble, traders push the asset price above its fundamental value in a dynamic way, driven by rational expectations about future price developments. At a previously...

We develop a model of rational bubbles based on the assumptions of unknown market liquidity and limited liability of traders. In a bubble, the price of an asset rises dynamically above its steady-state value, justified by rational expectations about future price developments. The larger the...

This paper proposes Spillover Persistence as a measure for financial fragility. The volatility paradox predicts that fragility builds up when volatility is low, which challenges existing measures. Spillover Persistence tackles this challenge by exploring a novel dimension of systemic risk: loss...

I develop a framework of the buildup and outbreak of financial crises in an asymmetric information setting. In equilibrium, two distinct economic states arise endogenously: "normal times", periods of modest investment, and "booms", periods of expansionary investment. Normal times occur when the...
