We explore the effects of forward guidance at the zero lower bound when there is uncertainty over the lift-off date arising from: (i) the imperfect credibility of time-inconsistent forward-guidance promises; (ii) incomplete communication. We use a simple New Keynesian model to demonstrate that a...

My paper, “Does the Fed control interest rates?” is in the 2013 Review of Asset Pricing Studies (Volume 3, pp. 180-199). The paper finds that the Fed controls the Federal Funds (FF) rate (the overnight rate on interbank borrowing of reserves). Other short-term rates are related to FF, but...

Are there limits to how far reductions in interest rates can boost aggregate demand? In particular, as interest rates fall to very low levels, does the effectiveness of monetary policy in boosting the economy wane? We provide evidence consistent with this hypothesis. Based on a panel of 18...

We review evidence on the Great Moderation together with evidence about volatility trends at the micro level to develop a potential explanation for the decline in aggregate volatility since the 1980s and its consequences. The key elements are declines in firm-level volatility and aggregate...

This study finds that a model with internal habit memory allowsto simultaneously explain a series of business cycle and asset pricing puzzles. Compared to the literature, the equity premium puzzle can be resolved in a model with endogenous labor, without giving rise to excessive risk free rate...

The author assesses the factors that determine market interest rates and the equilibrium conditions with respect to aggregate desired borrowings and savings. According to gain-loss utility, aggregate desired borrowings and savings are in equilibrium when market interest rates equal the...

Demographic developments have been regarded as one important cause of the long-termmovement in global interest rates. This paper provides empirical evidence of therelationship between demographics and interest rates over a wide sample of advanced andemerging market economies. It also finds that...

Despite massive large-scale asset purchases (LSAPs) by central banks around the world since the global financial crisis, there is a lack of empirical evidence on whether and how these programs affect the real economy. Using rich borrower-linked mortgage-market data, we document that there is a...

High public debt often produces the drama of default and restructuring. But debt is also reduced through financial repression, a tax on bondholders and savers via negative or below market real interest rates. After WWII, capital controls and regulatory restrictions created a captive audience for...
