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...

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...

The recent literature on endogenous economic growth allows for effects of fiscal policy on long-term growth. If the social rate of return on investment exceeds the private return, then tax policies that encourage investment can raise the growth rate and levels of utility. An excess of the social...

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....

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...

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...

This paper assesses the impacts of the WTO Government Procurement Agreement (GPA) on trade in both goods and services among members using a gravity model applied to a panel dataset covering 20 OECD countries over the period 1996-2008 for trade in goods and 1999-2008 for trade in services. The...

Large population / rapidly growing economies such as China and India have argued that in the upcoming UNFCCC negotiations in Copenhagen, any emission reduction targets they take on should be based on their intensity of emissions (emissions/$GDP) on a target date not the level of emissions. They...

Satisfactory calculations of the welfare cost of aggregate consumption uncertainty require a framework that replicates major features of asset prices and returns, such as the high equity premium and low risk-free rate. A Lucas-tree model with rare but large disasters is such a framework. In a...

This paper focuses on the causes of increased wage inequality in OECD countries in recent years and its decomposition into the component factors of trade surges in low wage products and technological change that has preoccupied the trade and wages literature. It argues that the length of...
