Financial Development and International Trade
This paper studies the industry-level and aggregate implications of financial development on international trade. I set up a multi-industry general equilibrium model of international trade with input-output linkages and heterogeneous firms subject to financial frictions. Industries differ in capital-intensity, which leads to differences in external finance dependence. The model is parameterized to match key features of firm-level data. Financial development leads to substantial reallocation of international trade shares from labor- to capital-intensive industries, with minor effects at the ...

Allocation and Employment Effect of the Paycheck Protection Program
The Paycheck Protection Program (PPP) was a large and unprecedented small-business support program enacted as a response to the COVID-19 crisis in the United States. The PPP administered almost $800 billion in loans and grants to small businesses through the banking system. However, there is still limited consensus on its overall effect on employment. This paper explores why it is challenging to estimate the effect of the PPP. To do so, we first focus on the timing of the allocation of PPP funds across regions and firms. Counties less affected by COVID-19 and with a larger presence of ...

Oil Price Fluctuations, US Banks, and Macroprudential Policy
Using US micro-level data on banks, we document a negative effect of high oil prices on US banks' balance sheets, more negative for highly leveraged banks. We set and estimate a general equilibrium model with banking and oil sectors that rationalizes those findings through the financial accelerator mechanism. This mechanism amplifies the effect of oil price shocks, making them non-negligible drivers of the dynamics of US banks' intermediation activity and of the US real economy. Macroprudential policy, in the form of a countercyclical capital buffer, can meaningfully address oil price ...

Financial Frictions, Financial Shocks, and Aggregate Volatility
I revisit the Great Inflation and the Great Moderation for nominal and real variables. I document an immoderation in corporate balance sheet variables so that the Great Moderation is best described as a period of divergent patterns in volatilities for real, nominal and financial variables. A model with time-varying financial frictions and financial shocks allowing for structural breaks in the size of shocks and the institutional framework is estimated. The paper shows that (i) while the Great Inflation was driven by bad luck, the Great Moderation was mostly due to better institutions; (ii) ...

The Macroeconomic Effects of the Tax Cuts and Jobs Act
This paper studies the macroeconomic effects of seven key TCJA provisions, including the tax cuts for individuals and businesses, the bonus depreciation of equipment, the amortization of R&D expenses, and the limits on interest deductibility. I use a dynamic general equilibrium model with interest deductibility and accelerated depreciation. I find that, initially, the tax reform had a small positive impact on output and investment. In the medium term, however, the effect on output will diminish, and the effect on investment will turn negative. The tax reform will depress investment in R&D. ...

Financial frictions, real estate collateral, and small firm activity in Europe
We observe significant heterogeneity in the correlation between changes in house prices and the growth of small firms across certain countries in Europe. We find that, overall, the correlation is far greater in Southern Europe than in Northern Europe. Using a simple model, we show that this heterogeneity may relate to financial frictions in a country. We confirm the model?s propositions in a number of empirical analyses for the following countries in Northern and Southern Europe: the United Kingdom, Norway, France, Italy, Spain, and Portugal. Small firms in countries with higher financial ...

How Does U.S. Monetary Policy Affect Emerging Market Economies?
The question of how U.S. monetary policy affects foreign economies has received renewed interest in recent years. The bulk of the empirical evidence points to sizable effects, especially on emerging market economies (EMEs). A key theme in the literature is that these spillovers operate largely through financial channels—that is, the effects of a U.S. policy tightening manifest themselves abroad via declines in international risky asset prices, tighter financial conditions, and capital outflows. This so-called Global Financial Cycle has been shown to affect EMEs more forcefully than advanced ...

Risk, Financial Development and Firm Dynamics
I document that the average productivity of firms tends to increase, and its variance to decrease, as they age. These two facts combined suggest that managers learn to reduce their mistakes as they operate. I develop a quantitative framework mimicking these dynamics and find that young firms have substantially higher financing costs due to lower and riskier returns. In this scenario, a reduction in the financial development of an economy raises disproportionately the cost of credit of young-productive firms increasing the input misallocation within this subgroup. To test the validity of the ...

Applications of Markov Chain Approximation Methods to Optimal Control Problems in Economics
In this paper we explore some benefits of using the finite-state Markov chain approximation (MCA) method of Kushner and Dupuis (2001) to solve continuous-time optimal control problems in economics. We first show that the implicit finite-difference scheme of Achdou et al. (2022) amounts to a limiting form of the MCA method for a certain choice of approximating chains and policy function iteration for the resulting system of equations. We then illustrate that, relative to the implicit finite-difference approach, using variations of modified policy function iteration to solve income fluctuation ...
