This paper reviews the leading ideas that have emerged within two paradigms of price adjustment. Neither, it appears, provides a satisfactory theoretical scheme when taken in isolation. This paper concludes that an attempt to merge the more convincing elements of each is needed, and some...

The problems involved in estimating real output that I discuss in this paper cause the official government statistics to underestimate of the rates of growth of real GDP, real personal income, and productivity. That underestimation is important not just to economists trying to understand where...

International trade is frequently thought of as a production technology in which the inputs are exports and the outputs are imports. Exports are transformed into imports at the rate of the price of exports relative to the price of imports: the reciprocal of the terms of trade. Cast this way, a...

The projected path of the U.S. national debt is the major challenge facing American economic policy. Without changes in tax and spending rules, the national debt will rise from 62 percent of GDP now to more than 100 percent of GDP by the end of the decade and nearly twice that level within 25...

Using a recursive empirical model of the real interest rate, GDP growth, and the primary government deficit in the U.S., I solve for the ergodic distribution of the debt/GDP ratio. If such a distribution exists, the government is satisfying its intertemporal budget constraint. One key finding is...

We examine austerity in advanced economies since the Great Recession. Austerity shocks are reductions in government purchases that exceed reduced-form forecasts. Austerity shocks are statistically associated with lower real GDP, lower inflation and higher net exports. We estimate a...

This paper uses the sequence of government budget constraints to motivate estimates of interest payments on the U.S. Federal government debt. We explain why our estimates differ conceptually and quantitatively from those reported by the U.S. government. We use our estimates to account for...

We introduce a solution technique for the study of discrete time stochastic models populated by long-lived agents. We introduce aggregate uncertainty and complete markets into a 'perpetual-youth' model of a kind first studied by Olivier Blanchard and we show that the pure-trade version of the...
