The Effects of Money-financed Fiscal Stimulus in a Small Open Economy

In this paper, we analyze the effects of money-financed (MF) fiscal stimulus and compare them with those resulting from a conventional debt-financed (DF) fiscal stimulus in a small open economy. We find that in normal times which is a period when a zero lower bound (ZLB) on the nominal interest rate is not applicable, MF fiscal stimulus is effective in increasing output. In a liquidity trap where the ZLB is applicable, even though the decrease in both consumer price index (CPI) inflation and output is more severe than in a closed economy when there is no fiscal response, MF fiscal stimulus is effective in stabilizing both. Accordingly, we show that even in an imperfect pass-through environment including a liquidity trap, an increase in government expenditure under MF fiscal stimulus is effective. In contrast, our policy implications concerning an increase in government expenditure under DF fiscal stimulus lie opposite to Gali, Jordi (2020), “The Effects of a Money-financed Fiscal Stimulus,” Journal of Monetary Economics, 115, 1-19, assuming a closed economy. In normal times, an increase in government expenditure under the DF scheme in a small open economy is more effective than in a closed economy, although Gali (2020) argues that it is much less effective. In a liquidity trap, an increase in government expenditure under the DF scheme is less effective, also in contrast to Gali (2020). We find that even in an imperfect pass-through environment, an increase in government expenditure under DF fiscal stimulus is not effective. Thus, in a small open economy, MF fiscal stimulus is not always essential in normal times, and in a liquidity trap, MF fiscal stimulus is more important than what Gali (2020) suggests because DF fiscal stimulus is not effective, irrespective of nominal exchange rate pass-through.
