Daily price movements of seventeen commodities are tested for the possible presence of nonlinear speculative bubbles during 1991-2012. A VAR model for logarithmic first differences of each is estimated with one-year Treasury bill rates, U.S. dollar value, a world stock market index, and an...

Daily price movements of seventeen commodities are tested for the possible presence of nonlinear speculative bubbles during 1991-2012. A VAR model for logarithmic first differences of each is estimated with one-year Treasury bill rates, U.S. dollar value, a world stock market index, and an...

A time series of the Shanghai stock index in China for the 1990s is studied for the possible existence of nonlinear speculative bubbles. Three alternative specifications of fundamentals are estimated using VAR models of domestic and international variables. These are subjected to regime...

Daily returns of stock markets in emerging markets in Asia, Africa, South America, and Eastern Europe from the early 1990s through 2006 are analyzed for the possible presence of nonlinear speculative bubbles. The absence of these is tested for by studying residuals of vector autoregressive-based...

Complexity research draws on complexity in various disciplines. This Handbook provides a comprehensive and current overview of applications of complexity theory in economics. The 15 chapters, written by leading figures in the field, cover such broad topic areas as conceptual issues,...

Emergence is often argued to be a deep property of complex systems, with such systems exhibiting wholes that are in some way greater than the sum of their parts. These ideas have played an important part in discussions of spontaneous order within Austrian economics, particularly by Hayek drawing...
