Abstract
Outlines previous research attempts to explain the behaviour of second moments of price and return distributions and theories of how Big Players (i.e. those with enough discretionary power to influence the market but little sensitivity to profit/loss consequences) affect the volatility and informational efficiency of markets. Contrasts the 1883‐1892 fluctuations in the exchange value of the Russian rouble under interventionist (i.e. big player) and non‐interventionist finance ministers; and analyses the statistics using GARCH techniques. Shows that under the Big Player, both unconditional variance and the persistence of conditional volatility increased. Suggests that policy regimes affect the degree of noise‐trader influence and calls for further research.

Abstract
Roger Koppl (2009, p. 1) argues that “Austrian economics is a school of thought within the broader complexity movement in economics.” Is he correct? Although there are many who have argued for some overlapping between the two, I shall argue that this is probably an overly strong statement. The main reason is that there are substantial elements and strands within Austrian economics that do not fit in with any of the multiple varieties of complexity theory, even though there are some that clearly do.

Abstract
Experts respond to the same incentives as people in other areas of human action, and in the same ways. This insight is a truism: Experts are ordinary people, not otherworld creatures. The disciplined pursuit of this common sense observation helps us to reach conclusions about experts that might be surprising or counterintuitive.

Abstract
Cognition and psychology have become central issues in economics. While this interest represents a radical change in economic theory, it does have a useful history that we believe is only partially recognized by contemporary economists. Although it is customary to cite Herbert Simon's important work in this regard,1 we suggest Hayek's earlier work The Sensory Order (1952) should enjoy similar billing.
