"Conceptual advances in pricing options and other complex financial products, along with improvements in computer and telecommunications technologies, have significantly lowered the costs of, and expanded the opportunities for, hedging risks that were not readily deflected in earlier decades. The new instruments of risk dispersal have enabled the largest and most sophisticated banks, in their credit-granting role, to divest themselves of much credit risk by passing it to institutions with far less leverage. Insurance companies, especially those in reinsurance, pension funds, and hedge funds continue to be willing, at a price, to supply credit protection.
These increasingly complex financial instruments have contributed to the development of a far more flexible, efficient, and hence resilient financial system than the one that existed just a quarter-century ago. After the bursting of the stock market bubble in 2000, unlike previous periods following large financial shocks, no major financial institution defaulted, and the economy held up far better than many had anticipated.
If we have attained a degree of flexibility that can mitigate most significant shocks--a proposition as yet not fully tested--the performance of the economy will be improved and the job of macroeconomic policymakers will be made much simpler.
Governments today, although still far more activist than in the nineteenth and early twentieth centuries, are rediscovering the benefits of competition and the resilience to economic shocks that it fosters. We are also beginning to recognize an international version of Smith's invisible hand in the globalization of economic forces.
Whether by intention or by happenstance, many, if not most, governments in recent decades have been relying more and more on the forces of the marketplace and reducing their intervention in market outcomes. We appear to be revisiting Adam Smith's notion that the more flexible an economy, the greater its ability to self-correct after inevitable, often unanticipated disturbances. That greater tendency toward self-correction has made the cyclical stability of the economy less dependent on the actions of macroeconomic policymakers, whose responses often have come too late or have been misguided.
It is important to remember that most adjustment of a market imbalance is well under way before the imbalance becomes widely identified as a problem. Individual prices, exchange rates, and interest rates, adjust incrementally in real time to restore balance. In contrast, administrative or policy actions that await clear evidence of imbalance are of necessity late."
