Davig and Leeper (2007) have proposed a condition they call the generalized Taylor principle to rule out indeterminate equilibria in a version of the New Keynesian model, where the parameters of the policy rule follow a Markov-switching process. We show that although their condition rules out a...

The issue of uncovering the effects of monetary policy is far short of resolution. In the identified VAR literature, restrictions have been imposed to identify the effects of unpredictable monetary policy disturbances. We offer critical views on the unreasonable assumptions in the existing work...

Using three unique micro datasets, we find that an unexpected and unprecedented loosening of China's LTV policy for non-primary houses fueled the entire mortgage boom during 2014Q4-2016Q3. The mortgage expansion disproportionately increased the share of mortgages to middle-aged homeowners with...

We explore an important role of monetary-fiscal policy interactions in explaining three stylized facts: (1) a positive correlation of stock and bond returns in 1971-2001 and a negative one after 2001, (2) a negative correlation of consumption and inflation in 1971-2001 and a positive one after...

The authors present a framework for computing and evaluating linear projections of macro variables conditional on hypothetical paths of monetary policy. A modest policy intervention is a change in policy that does not significantly shift agents' beliefs about policy regime and does not generate...

We construct linear projections of macro variables conditional on hypothetical paths of monetary policy, using as an example an identified VAR model. Hypothetical policies are restricted to ones where both the policy intervention and its impacts are consistent with history -- otherwise the...

We consider a life-cycle model with idiosyncratic risk in labor earnings, out-of-pocket medical and nursing home expenses, and survival. Partial insurance is available through welfare, Medicaid, and social security. Calibrating the model to the United States, we find that 12 percent of aggregate...

The welfare gain to consumers from the introduction of personal computers is estimated here. A simple model of consumer demand is formulated that uses a slightly modified version of standard preferences. The modification permits marginal utility, and hence total utility, to be finite when the...

We construct a unified objective measure of health status: the frailty index, defined as the cumulative sum of all adverse health indicators observed for an individual. First, we show that the frailty index has several advantages over self-reported health status, particularly when studying...
