Abstract: What motivates ESG integration? I find both non-pecuniary and risk-mitigating preferences explain its prominence. A novel test based on changes in mutual funds’ portfolio holdings and several empirical findings establish the two widely endorsed ESG ratings proxy these preferences. With this, I show each preference induces sizable equity premium identified through option-implied expected returns. Due to unexpectedly persistent demand growth for ESG-conscious assets, realized returns mask true ESG pricing effects, especially those attributable to non-pecuniary preference. Consequently, this paper lends support to recent theoretical frameworks with non-pecuniary preference and explains why empirical literature has lacked consensus.

Abstract: We build a financial intermediation model wherein bank and fintech intermediaries compete or partner within frictional credit markets. Banks and fintechs differ in their enforcement technology and funding cost. Fintech lenders can directly extract a fraction of borrowers' output upon default, while banks rely on collateralized lending. The model explains the emergence and coexistence of three forms of lending associated with: (i) standalone banks, (ii) standalone fintechs, and (iii) bank-fintech partnerships. Fintech disruption enhances market competition and facilitates credit intermediation to previously underserved borrowers, but crowds out bank-captive borrowers as traditional banks experience low profitability and get displaced. In equilibrium, fintech entry and the prevalence of bank-fintech partnerships do not necessarily benefit all borrowers, leading to ambiguous credit and welfare effects at the aggregate level.

Abstract: The zero lower bound (ZLB) constraint on interest rates makes speed limit policies (SLPs)—policies aimed at stabilizing the output growth—less effective. Away from the ZLB, the history dependence induced by a concern for output growth stabilization improves the inflation-output tradeoff for a discretionary central bank. However, in the aftermath of a deep recession with a binding ZLB, a central bank with an objective for output growth stabilization aims to engineer a more gradual increase in output than under the standard discretionary policy. The anticipation of a more restrained recovery exacerbates the declines in inflation and output when the lower bound is binding.

Works in Progress

Abstract: We develop a theory centered around the role of financial technology and loan officers in credit intermediation. Within a general equilibrium setting, we study how imperfections stemming from either credit or labor markets can shape bank lending decisions and contractual terms, and eventually spill over to real economic activity. Our main contribution resides in (i) designing a double-layered search model for both labor and credit, (ii) exploring how financial technology interacts with the employment of loan officers, bank monitoring, and aggregate lending, and (iii) analyzing its welfare implications.

Abstract: We examine the implications of less powerful forward guidance for optimal policy using a sticky-price model with an effective lower bound (ELB) on nominal interest rates as well as a discounted Euler equation and a discounted Phillips curve. When the private-sector agents discount future economic conditions more in making their decisions today, a future rate cut becomes less effective in stimulating current economic activity. Under a wide range of plausible degrees of discounting, it is optimal for the central bank to compensate for the reduced effect of a future rate cut by keeping the policy rate at the ELB for longer.
