Fiscal Stimulus: A Neoclassical Perspective

Holger Strulik () and Timo Trimborn ()

Hannover Economic Papers (HEP) from Leibniz Universität Hannover, Wirtschaftswissenschaftliche Fakultät

Abstract: Can a large-scale defcit spending program speed up recovery after recession? To answer that question we calibrate a standard neoclassical growth model with US data and assume that an exogenous shock has driven aggregate output far below steady-state level. We calibrate the model such that a permanent increase of government expenditure is effective in raising output. We then show that "fiscal stimulus", i.e. a temporary increase of government expenditure is not only ineffective but detrimental. Even before the spending program expires, aggregate output is lower than it could be without fiscal stimulus. We show the generality of this result w.r.t. size and persistence of the shock, size of the government spending multiplier, and the scale and duration of the stimulus program. Using a phase diagram we provide the economic intuition for our unpleasant finding and explain why, generally, private capital stock reaches its lowest level when a deficit spending program expires. We also show how an accompanying temporary cut of capital income taxes helps to prevent the negative repercussion of deficit spending on economic recovery.
