PhD Candidate in Economics

Industrial Organization Financial Economics

Across my projects, I study how competition, market structure, spatial frictions, and technological change shape firm behavior and consumer welfare, with a particular focus on banking and financial markets. My work combines empirical and structural approaches to understand how firms adjust their locations, technologies, and other strategic decisions.

My broader research interests include financial regulation and stability, transportation, and environmental economics. Before beginning my PhD, I worked at Peru's Ministry of Economy and Finance and at APOYO Consultoria. In 2025, I completed a PhD internship at the Bank of England.

Outsourcing and competition in the banking sector: The rise of Cloud Service Providers

With Peter Eccles and Paolo Siciliani

Abstract

This paper studies the effects of banks’ outsourcing agreements with Cloud Service Providers (CSPs) in the UK banking sector. CSP spending is associated with lower operating costs and higher deposits, with reduced-form effects concentrated among large institutions. We estimate a structural model of competition in the deposit market to quantify depositor-demand effects from CSPs. We find that these benefits are substantially larger for small and medium banks and building societies. We use the model to conduct two counterfactual analyses. First, restricting cloud outsourcing before its widespread adoption increases market concentration, reduces the market shares of smaller institutions, and lowers depositor welfare. Second, reducing capital requirements raises welfare through funding-cost effects but weakens incentives for CSP adoption, offsetting roughly 32% of the direct welfare gain. Our findings suggest that cloud outsourcing has partly reduced technological barriers to competition in banking markets.

Countercyclical Capital and Reserve Requirements as Macroprudential Stabilizers

With Diego Bohorquez

Abstract

This paper studies how reserve requirements and countercyclical capital requirements interact in stabilizing the business cycle. Using a small open-economy DSGE model with nominal and financial frictions, we characterize optimal simple rules for monetary and macroprudential policy under alternative central bank objectives. Reserve requirements mainly affect liquidity and funding conditions, while capital requirements act more directly on lending capacity and loan spreads, generating potentially different effects on credit, output, and inflation that matter for policy design. Both instruments can bring significant stabilization benefits when included in the policy mix, particularly once financial stability is part of the central bank’s objective. When used separately to stabilize credit, capital requirements are more effective than reserve requirements. However, when both tools are assigned different objectives, the optimal division of tasks varies across shocks, with reserve requirements assigned to credit and capital requirements to output in most cases. The results highlight gains from specialization across macroprudential instruments with distinct transmission channels.
