Résumé Firm entry and capital investment both vary over the business cycle. This paper analyzes the role of the firm entry delay option (waiting option) in the joint dynamics of firm entry and investment in a news-driven RBC model. We introduce the waiting option by restricting the number of potential firm entrants and demonstrate that the combination of news shocks and the waiting option effect yields empirically plausible joint dynamics of firm entry and investment over the business cycle. In contrast, the model without the entry delay option produces excessively volatile firm entry. We rationalize our findings using an analytical real-option model of firm entry.

Résumé Episodes of low natural interest rates, even transitory, pose a challenge to monetary policy, by possibly causing the effective lower bound (ELB) on the policy rate to bind. Those episodes are more likely to occur not only when the natural rate is low on average but also when fluctuations around its average level are large. We study the responsiveness of the natural interest rate to structural aggregate shocks affecting the aggregate supply of and demand for savings. Using a quantitative overlapping-generations model, we trace back this responsiveness to the slopes of aggregate savings supply and demand curves and argue that both curves have likely flattened over the past four decades in the US This implies a greater sensitivity of the natural interest rate to structural shocks affecting the supply of and demand for aggregate savings – making it more likely, all else equal, that it fall into negative territory.

Résumé Abstract In this paper, we develop an overlapping generations model with endogenous fertility and calibrate it to the Swedish historical data in order to estimate the economic cost of the 1918–19 influenza pandemic. The model identifies survivors from younger cohorts as main benefactors of the windfall bequests following the influenza mortality shock. We also show that the general equilibrium effects of the pandemic reveal themselves over the wage channel rather than the interest rate, fertility or labor supply channels. Finally, we demonstrate that the influenza mortality shock becomes persistent, driving the aggregate variables to lower steady states which costs the economy 1.819% of the output loss over the next century.

Résumé Recessions are often accompanied by heightened uncertainty. We look at the effect of endogenous uncertainty on aggregate demand and its implications for monetary policy. We enrich a non-linear New-Keynesian model with imperfect noisy information, where the precision of signals is pro-cyclical. The endogenous uncertainty channel amplifies aggregate demand effects through precautionary saving. Ultimately, it can even reverse sign of the output-gap response to a supply shock. Monetary policy can eliminate both pricing and information-induced inefficiencies by closing the output gap. Based on U.S. household income forecast errors data, we estimate a sizable and significant degree of pro-cyclicality in the precision of signals.

Résumé Endogenous uncertainty acts as an aggregate-demand amplification mechanism of supply shocks. Using U.S. data, we first stress that taking into account time-varying macroeconomic uncertainty leads to a significantly stronger recession and less inflationary pressures, in response to a TFP shock. In addition, we show empirically that households' misperception increases during recessions. To rationalize these findings, we build a noisy-information New-Keynesian model where the precision of signals increases with economic activity. Pro-cyclical precision of information gives rise to an amplified precautionary saving behavior. A fullfledged model parametrized by using consumer-based forecast errors generates a demandlike recession of supply shock.
