so forth), incentives to take advantage of the less informed swelled, fueling excessive risk taking with someone else’s money. At the same time, the multiplication of agents and complex instruments aggravated the problems of asymmetric information by producing an increase in systemic opacity (Ashcraft and Schuermann 2008; Gorton 2008). The emergence of these “second-generation” asymmetric information problems runs contrary to the naive view that the reduction in transaction (including informational) costs should gradually dilute the agency problems associated with asymmetric information. While it seemed natural to expect that better and cheaper information would give the agent a better handle on the principal, better information and lower transaction costs also attracted new agents and promoted new instruments. Thus, the new nodes of agency frictions (along the originate-and-distribute chain, for example) arose at a faster pace than the ability of principals to catch up. However, new market failures also proliferated, and perhaps more treacherously, well beyond the confines of the information asymmetry paradigm, deeply involving the newer and less familiar territory of the collective cognition and collective action paradigms, as discussed below.7 The apparent success of monetary policy in stabilizing inflation and smoothing out the business cycle fueled a mood of excessive optimism and exuberance, reflecting collective cognition failures associated with uncertainty and bounded rationality. As the observed macrofinancial volatility declined, making pricing more predictable and deepening market liquidity, financial innovation was quickened, risk appetite boosted, and highly procyclical leveraging stimulated. The low-volatility environment had the immediate mechanical effect of reducing values at risk, and the more it persisted, the more it fed collective cognition failures and mood swings. The prevailing feeling was that “this time around, things are different and the good times are here to stay.” Of course, when unexpected icebergs popped up on the horizon (say, an initial but nationwide downturn in housing prices in the United States), moods swung sharply to panic. These cognition failures fed on the process of financial innovation. It privately paid to develop new instruments; it did not pay to fully understand their potentially adverse systemic implications. More broadly, it generally paid to understand how risks and returns compared across a
