Over the last decade, empirical studies analyzing macroeconomic conditions that may affect the size of government spending multipliers have flourished. Yet, in spite of their obvious public policy importance, little is known about public investment multipliers. In particular, the clear...

This paper incorporates the productivity role of government expenditure into the imperfectly competitive macroeconomic model and re-examines the important findings on the fiscal multiplier proposed by Dixon (1987), Mankiw (1988), and Startz (1989). Generally speaking, we find that the classical...

This paper quantitatively assesses the macroeconomic effects of the recently agreed U.S. bipartisan infrastructure spending bill in a neoclassical growth model. We add to the literature by considering a more detailed tax structure, different types of infrastructure spending and linkages between...

This paper estimates the macroeconomic effects of government spending shocks in New Zealand. Using a structural vector autoregression (SVAR) model, I find small output multipliers for government consumption but large multipliers for government investment. Importantly, the real exchange rate...

This paper explores whether public investment crowds out or crowds in private investment. To this aim, we build a database of about half a million firms from 49 countries. We find that the effect of public investment on corporate investment depends both on leverage and financial constraints....

We study the effectiveness of public investment in stimulating an economy stuck in a liquidity trap. We do so in the context of a tractable new-Keynesian economy in which a fraction of government spending increases the stock of public capital subject to a time-to-build constraint. Public...

Public investment represents a non-negligible fraction of total public expenditures. Yet, theoretical studies of the effects of public spending when the economy is stuck in a liquidity trap invariably assume that government expenditures are entirely wasteful. In this paper, we consider a...

We analyze the welfare multipliers of public spending (the consumption equivalent change in welfare for one dollar change in public spending) in a DSGE model. The welfare multipliers of public infrastructure investment are positive if infrastructure is sufficiently effective. When the...

In this analysis, we discuss two measures that have been used by economists to measure changes in macroeconomic policies: the dynamic multiplier and the impulse response function. These multipliers are identical under specific conditions, e.g., by imposing certain restrictions on a VAR model....

The paper studies the dynamic output effects of public infrastructure investment in a small open economy. We develop an overlapping generations model that includes a production externality of public capital and a wealth effect on labor supply. Public capital enters the firm's production function...
