Economic Openness and Fiscal Multipliers

International Economic Journal, 2017, vol. 31, issue 1, 1-35

Abstract: Recent empirical findings attribute a central role to the degree of economic openness to determine the size of the fiscal multiplier. See, for instance, Ilzetzki et al. (2013) [How big (small?) are fiscal multipliers? Journal of Monetary Economics, 60(2), 239–254]. However, traditional macroeconomic models have difficulties to account for this evidence. By introducing ‘deep-habit’ formation into a New Keynesian small open economy model, this paper provides a theoretical framework which is able to attest for the new empirical evidence. Deep habits give rise to counter-cyclical firm markups, which are crucial to generate effects of openness on the fiscal multiplier as found in the data. We study three dimensions of economic openness: exchange rate flexibility, trade openness, and capital mobility. In line with the empirical findings, we report a negative relationship between measures of economic openness and the fiscal multiplier.
