Markets are central to modern society, so their failures can be devastating. Here, we examine a prominent failure: price bubbles. Bubbles emerge when traders err collectively in pricing, causing misfit between market prices and the true values of assets. The causes of such collective errors remain elusive. We propose that bubbles are affected by ethnic homogeneity in the market and can be thwar...

The subject of the paper by David Gruen, Michael Plumb and Andrew Stone — how monetary policy should respond to asset prices — is obviously an important one. The formation of bubbles in asset prices and the eventual demise of those bubbles have the potential to cause damage to our economic and fi nancial systems. Macroeconomic instability in the form of unwelcome variability of output and infl ...

We construct asset markets of the type studied in Smith et al. (1988), in which price bubbles and crashes are widely observed. In addition to a spot market, there are futures markets in operation, one maturing in each period of the life of the asset. We find that when futures markets are present, bubbles do not occur in the spot markets. The futures markets seem to reduce the speculation and th...

Groups of humans routinely misassign value to complex future events, especially in settings involving the exchange of resources. If properly structured, experimental markets can act as excellent probes of human group-level valuation mechanisms during pathological overvaluations--price bubbles. The connection between the behavioral and neural underpinnings of such phenomena has been absent, in p...

Bubbles in asset prices have fascinated researchers in finance. Identify asset bubbles, by circumstances, on the stock market has been a growing number of research theoretical and empirical. On a theoretical level, it was assumed that the price dynamics reflect irrational behavior of economic agents and, therefore, should be excluded from a deal with the truly rational economic agents Burmeiste...
