Most growth theorists agree that understanding the economics of innovation and technological change is central to understanding why some countries are richer and/or grow faster than other countries. The driving force behind recent developments in endogenous innovation models of growth is a...

An SVAR in US federal spending, federal revenue, and GDP is a standard setting for the study of the impact of fiscal shocks. An appealing feature of identifying a fiscal shock with an external instrument is that one can find the effects of that shock without fully identifying the SVAR. But we...

What do we know about the output effects of fiscal policy in low income countries (LICs)? There are very few empirical studies on the subject. This paper fills this gap by estimating the output effects of government spending shocks in LICs. Our analysis-based on the local projection method-finds...

The Structural Vector Auto-regression (SVAR) approach to estimating fiscal multipliers, following the seminal paper by Blanchard and Perotti (2002), has been widely applied in the literature. In our pa-per we discuss the interpretation of these estimates and suggest that they are more useful for...

We estimate the effect of government spending shocks on the US economy with a time-varying parameter vector autoregression. The recent Great Recession period appears to be characterized by uniquely large impulse responses of output to fiscal shocks. Moreover, the particularity of this period is...
