We assess how financial development affects innovation. For this purpose, we employ a unique Research Quotient data set from 1980 to 2018, and observe significant inverted-U effects of financial development on innovation for equity and credit markets. Specifically, the effects of the markets are sector-specific, implying that the inverted-U effect of the equity market on innovation is mainly driven by its diminishing effect on innovation in high-technology industries, while credit markets mostly affect innovation in non-high-technology industries. Regarding the mechanism, we posit that the inverted-U shape between finance and innovation may be explained by the disproportionate funds allocation-induced market concentration.

We evaluate the forecasting ability of several popular measures of uncertainty. We construct new real-time versions of both macro-economic and financial uncertainty, and analyze them together with their ex post counterparts. We find some explanatory power in all uncertainty measures, with relatively good performance by ex post macro-economic and financial uncertainty. However, real-time versions perform only about as well as other uncertainty measures such as economic policy uncertainty (EPU), a finding we relate to data revisions in the construction of ex post uncertainty. Real-time data and estimation considerations are highly consequential, owing to look-ahead bias. Real-time uncertainty forecasts real-time outcome variables better than it forecasts ex post revised outcome variables.

This paper contributes to and extends our current understanding of information frictions in expectations. I first propose a new framework for estimating noisy information using individual forecasts. I further extend this framework to incorporate misperceptions on the part of economic agents about the persistence of the underlying process being forecasted. Applying this framework to the U.S. inflation, forecasts of professional forecasters suggest a systematic overestimation on the part of forecasters of the persistence of inflation in addition to the presence of noisy signals. Using a structural model that incorporates both noisy signals and misperceptions of persistence, I quantify the relative importance of each channel in accounting for the expectations formation process of these agents. The results indicate that, even for professional forecasters, there are multiple forces that generate economically significant deviations from full information.

What happens when banks compete with deposit and loan contracts contingent on macro-economic shocks? The private sector insures the banking system efficiently against crises through such contracts when failing banks go bankrupt. When risks are large, banks may shift part of the risk to depositors who receive state-contingent contracts. In contrast, when failing banks are rescued, new phenomena such as risk magnification emerge. Depositors receive noncontingent contracts, while loan contracts demand high repayment in good times and low repayment in bad times. Banks overinvest and generate large macro-economic risks, even if the underlying productivity risk is small or zero.

Using supervisory data on small and midsized nonfinancial enterprises (SMEs), we find that those SMEs with higher leverage faced tighter constraints in accessing bank credit after the COVID-19 outbreak in spring 2020. Specifically, SMEs with higher pre-COVID leverage obtained a smaller volume of new loans and had to pay a higher spread on them during the pandemic period. Consistent with an inward shift in loan supply, these effects were concentrated in loans originated by banks with below-median capital buffers. Highly levered SMEs that relied on low-capital large banks for funding before the pandemic were not able to substitute to other sources of debt financing and thus experienced more of a reduction in total debt as well as a decline in investment and employment. On the other hand, the unprecedented public support, especially the Paycheck Protection Program (PPP), mitigated the adverse real effect stemming from bank credit constraints.

In a business cycle model with endogenous firms' dynamics and debt renegotiation, we show that during financial crises loan forbearance does not harm the economy unless banks imperfectly monitor loans, and loan opacity worsens banks' moral hazard problem. Aggressive interest rate reductions and quantitative easing limit defaults and financial crisis-induced output contractions without hampering the entry of new firm entries. The decline in the natural interest rate, due to slower productivity growth and persistent liquidity shocks, potentially explains the observed long-term trend in nonperforming loan shares.

We estimate a New Keynesian model incorporating two notable features: bounded rationality and the zero lower bound on the nominal interest rate. Our Bayesian estimation of a nonlinear model shows that the model with bounded rationality better fits the U.S. data than its rational expectations counterpart, and that both households and firms exhibit a substantial degree of bounded rationality. Moreover, we demonstrate that bounded rationality expands a parameter region in which the model can be estimated and weakens the power of forward guidance.

We analyze the gross worker flows over the life cycle by constructing a quantitative general equilibrium model. Using U.S. data, we first document the life-cycle patterns of flows across different labor market states (employment, unemployment, and not in the labor force), as well as job-to-job transitions. We then build a model of the aggregate labor market that incorporates the life cycle of workers, consumption-saving decisions, and labor market frictions. We estimate the model and use it to examine the effects of policies on aggregate labor market outcomes. In particular, we analyze a taxes-and-transfers policy and an unemployment insurance policy.

The Cobb-Douglas matching function is ubiquitous in labor search and matching models, even though it imposes a constant matching elasticity that is unlikely to hold empirically. To examine the implications of this discrepancy, this paper uses a general constant returns to scale matching function to derive conditions that show how the cyclicality of the matching elasticity affects the shape of the job finding rate as a function of productivity and amplifies or dampens nonlinear labor market dynamics. It then shows that modest variation in the matching elasticity, consistent with recent estimates, significantly affects higher order moments and optimal policy. This motivates research that can provide greater clarity on the matching function specification.

We examine ways to describe the maturity structure of public debts using few parameters. We compile a novel data set of all promised future payments for U.S. and UK government debt from every month since 1869, and more recently for Peru, Poland, Egypt, and Nigeria. We show there is a unique parametric form which does not arbitrarily restrict debt issuance. We use this model to parsimoniously describe the evolution of public debt maturities and to characterize the relationship between maturity and the term structure of interest rates in the United States since 1940.
