In emerging markets, unexpected public expenditure reductions increase firm-level investment, which quickly surpasses pre-shock levels after a temporary contraction, owing to a decline in financing costs. Consistent with the role played by financing cost dynamics and financial frictions, we show that countries with lower sovereign credit ratings (those that are not investment grade) experience a sharper boost in investment. In addition, we find that investment's recovery is facilitated by trade openness, public spending predictability, and exchange rate flexibility. In fact, exchange rate flexibility facilitates the real depreciation that result from the fiscal adjustment, which decreases (relative) domestic demand for non-tradable (akin to Diaz-Alejandro, 1966) and increases external demand for tradables, boosting investment. We show that adjustment composition matters: reductions in public consumption (vis-à-vis public investment) yield larger private investment contractions on impact but result in quicker and more sustainable recoveries. Exploiting firm-level heterogeneity we show that investment's expansion is stronger in the tradable-sector, in larger, and in less indebted firms. We provide evidence that the medium-term benefits of fiscal shocks to firm-level activity outweigh their short-run costs.
