We examine whether a simple agent—based model can generate asset price bubbles and crashes of the type observed in a series of laboratory asset market experiments beginning with the work of Smith, Suchanek and Williams (1988). We follow the methodology of Gode and Sunder (1993, 1997) and examine the outcomes that obtain when populations of zero—intelligence (ZI) budget constrained, artiÞcial ag...

The methods of the panel KSS unit root test with a Fourier function and the SPSM process are likewise used. The panel KSS unit root test with a Fourier function considers the problem of non-lineari...

With short-sale constraints, an asset owner has an option to sell the asset to other overconfident agents when they have more optimi...
