The fiscal theory of the price level (FTPL) has been active for 30 years, and the interest in this theory grew with the recent global surges in inflation and government spending. This study applies the FTPL to 37 OECD countries for 2020-2022. The theory's centerpiece is the government's...

For U.S. annual data that include WWII, the estimated multiplier for temporary defense spending is 0.4-0.5 contemporaneously and 0.6-0.7 over two years. If the change in defense spending is "permanent" (gauged by Ramey's defense-news variable), the multipliers are higher by 0.1-0.2. The...

In neoclassical growth models with diminishing returns to capital, a country's per capita growth rate tends to be inversely related to its initial level of income per person. This convergence hypothesis seems to be inconsistent with the cross-country evidence, which indicates that per capita...

Models of endogenous economic growth can generate long-term growth without relying on exogenous changes in technology or population. A general feature of these models is the presence of constant or increasing returns in the factors that can be accumulated. I use some models of this type to study...

I extend existing models of endogenous economic growth to incorporate a government sector. Production involves private capital (broadly defined) and public services. There is constant returns to scale in the two factors, but diminishing returns to each separately. Public services are financed by...

The British data from the early 1700s through World War I provide an unmatched opportunity for studying the effects of temporary changes in government purchases. In this paper I examine the effects of these changes on interest rates, the quantity of money, the price level, and budget deficits....

Because of a small direct negative effect on private spending, temporary variations in government purchases as in wartime, would have a strong positive effect on aggregate demand. Intertemporal substitution effects would direct work and production toward these periods where output was valued...
