I am a PhD candidate in Economics at Indiana University, specializing in Applied Economics with focus on International Trade and Political Economy. My current main research focuses on the dynamics of trade agreements, customs union stability, and policy coordination across emerging economies, particularly in Latin America. I also work at the intersection between Public Finance and Political Economy, with special focus on public banks, budgetary processes and social expenditure. Currently, I am also a Graduate Assistant at the Tobias Center for Innovation in International Development.

External Negotiations and Customs Union Stability
Guilherme Paiva Pinto • Job Market Paper
Persistent exit threats challenge the stability of customs unions, yet withdrawals are rare. This paper applies a structural model to study internal stability under external trade pressures within Mercosur, the largest free trade agreement in South America. The framework incorporates external bargaining, asymmetric tariffs, and is calibrated with sectoral trade data from 2004–2017, using counterfactual negotiations with the United States, China, and the European Union.
I document gains and losses from scenarios of single-country or bloc negotiations under each setup. Results show that smaller members gain more from bloc negotiations in GDP terms; although larger members also gain, they face concentrated industry losses, helping explain why the bloc stumbles in large negotiations. Benefits from joint negotiation vary widely, with small countries gaining the most while others experience limited improvements.

This study advances a quantitative political economy analysis of development banking within federative systems, focusing on Brazil's National Bank for Economic and Social Development (BNDES). Moving beyond traditional fiscal transfer models, we investigate the mechanisms through which federal credit operations are allocated to municipal governments, emphasizing the political incentives that influence these disbursements.
We adapt the Strategic Partisan Transfers Hypothesis (SPTH) to the development banking context, formalizing the interaction between federal, state, and local political alignments within Brazil's regulatory structure.

Tariff Cuts, External Shocks, and Strategic Inputs: The EU-Mercosur Agreement in a Changing World
Third paper • Work in progress
This paper studies whether the world economy changed in ways that made the long-delayed EU-Mercosur tariff bargain easier to defend. I code Annex 2-A, the product-level tariff schedule, and evaluate it across benchmark economies from 2007 to 2022 in a six-region, 49-sector quantitative trade model.
The tariff component generates small aggregate gains, so the main result is incidence: manufacturing losses in Argentina and Brazil remain concentrated, EU agriculture remains politically exposed, and external tariff-risk and strategic-input scenarios help explain why the agreement became economically more relevant despite modest tariff-only effects.
