The Government

In this paper, I examine the role of government spending persistence on fiscal multipliers at the zero lower bound (ZLB) in a more realistic environment while keeping the model simple enough to identify mechanisms driving the result. In particular, I build on a standard dynamic New Keynesian (DNK) model with an occasionally binding ZLB and Rotemberg pricing with rebates, where the probability of hitting the ZLB and the government purchase shock are in line with US data. Moreover, I compute the multiplier in a state that mimics the Great Recession. The main findings of the paper are as follows: (1) the multiplier is non-monotonic in the persistence of government spending while the economy is at the ZLB; (2) given the persistence estimated from US data, the multiplier is 1.25; and (3) in the framework with perfect foresight or with aggregate resource cost for adjusting prices, the multiplier is around 1 or less.

Low Levels

At the zero lower bound, the New Keynesian model predicts that output and inflation collapse to implausibly low levels, and that government spending and forward guidance have implausibly large effects. To resolve these anomalies, we introduce wealth into the utility function; the justification is that wealth is a marker of social status, and people value status. Since people partly save to accrue social status, the Euler equation is modified. As a result, when the marginal utility of wealth is sufficiently large, the dynamical system representing the zero-lower-bound equilibrium transforms from a saddle to a source—which resolves all the anomalies.

Parameter Values

We build a medium-scale DSGE model and calibrate it to fit the main macroeconomic variables during the US Great Recession. Using it to evaluate the welfare effects of increasing government consumption at the zero lower bound beyond what was actually observed in the data, we reach three main results. First, the increase in government consumption after 2008, albeit small in present value terms, was close to optimal. Second, frontloading the same stimulus would have been welfare-improving. Third, larger welfare effects occur in our model for parameter values implying either large welfare costs of modest recessions (e.g., high consumption curvature), or outright large recessions.
