The marginal cost of plant capacity, measured by the price of equity is significantly procyclical. Yet, the price of a major intermediate input into expanding plant capacity, investment goods, is coutercyclical. The ratio of these prices is Tobin's q. We interpret the fact that Tobin's q differs...

We review the fiscal theory of the price level. We place special emphasis on the theory's implications for the feasibility of price stability.

The `ideal' band pass filter can be used to isolate the component of a time series that lies within a particular band of frequencies. However, applying this filter requires a dataset of infinite length. In practice, some sort of approximation is needed. Using projections, we derive...

What is the best way to achieve price stability? Conventional wisdom says that a tough, independent central bank is all that is necessary. However, a new view—the fiscal theory of the price level—argues that an appropriate fiscal policy is also required, no matter how tough the central bank...

The motive to hold inventories purely in the hope of profiting from a price increase is called the speculative motive. This motive has received considerable attention in the literature. However, existing studies do not have a clear implication for how large it is quantitatively. This paper...

We develop optimal finite-sample approximations for the band pass filter. These approximations include one-sided filters that can be used in real time. Optimal approximations depend upon the details of the time series representation that generates the data. Fortunately, for U.S. macroeconomic...

A review of the theoretical and empirical case for disinflationary economic growth, showing that, contrary to popular wisdom, it is quite possible to have a booming economy without an acceleration in the price level.

Lots of counties experience major job loss, but why they do and how well they recover is more of a mystery.
