Will public deficit reduction encourage private sector growth, or undermine a needed stimulus to recovery & lead to Japan-style stagnation?

Economists sharply disagree on what many are now calling “the austerity debate.” Some prominent economists (for example, INET Advisor Kenneth Rogoff) believe that cutting deficits and reducing debt is essential to inspire confidence in financial markets and to ensure that long-term economic growth is not damaged. Others (for example Paul Krugman and Robert Skidelsky, who spoke at INET’s inaugural conference) think that any attempt to reduce expenditures today will be self-defeating since it will further weaken the economy, lead to lower growth and reduced tax revenues in the future, and so greater deficits and debt in the end.
