On Jul 21, 2009, the House Financial Services Committee conducted a hearing to discuss the concept of how to regulate "systemic risk" to the financial system. At that hearing, Alice M. Rivlin, Ph.D., an economists with the Brookings Institution and visiting professor at Georgetown University, explained the cause of the world economic crises in one sentence. In recent years, anti-regulatory ideology kept the US from modernizing the rules of the capitalist game in a period of intense financial innovation and allowed perverse incentives to creep in, opined Professor Rivlin. The professor called for expanded powers for the Federal Reserve to monitor and regulate leverage, which financial institutions use to inflate speculative bubbles. In addition to creating an institutional framework charged with identifying and correcting regulatory shortcomings, Dr. Rivlin proposed the creation of a "Bubble Threat Warning System," within the Fed. The financial sector needs affirmative and efficient regulation, and not just a collection of bureaucrats who like to watch.
