82.º Congresso Anual do International Institute of Public Finance

Public finances are under increasing strain in many parts of the world, reflecting a combination of slowing growth, rising debt levels, and heightened uncertainty in global markets. Advanced economies face mounting fiscal pressures linked to aging populations, structural deficits, and the long-term costs of health and social programs. In emerging and developing economies, governments must manage more volatile revenue streams, limited access to financing, and the persistent effects of economic shocks. Across different country contexts, these pressures have challenged established policy frameworks and raised new questions about the sustainability and effectiveness of current fiscal strategies. Given the high degree of global economic interconnectedness, the difficulties countries face in maintaining stable public finances have implications that extend beyond national borders. Fiscal consolidation efforts, debt restructuring processes, and responses to inflation can affect trade patterns, investment flows, and development prospects worldwide. At the same time, this period of fiscal turbulence provides an opportunity to reassess policy tools, draw on new analytical insights, and learn from the varied experiences of countries confronting similar constraints.
The keynote lectures of the conference will consider these issues and explore how governments might adapt public finance practices to better address the challenges ahead.
The conference will also host several events such as a mentoring program for young scholars in the field, and a networking reception for female scholars.

Prospective contributors, both practitioners and academics, are invited to submit papers on any topic within the field of public economics. The papers to be presented at the IIPF Congress will be selected by the Scientific Committee. Only completed papers in PDF format will be considered. Non–IIPF members must pay a submission fee of €20. Presenting authors from lower-income countries may apply for potential travel grants (within the submission form).

Acceptance decisions will be communicated in April 2026. Decisions on contributions from participants who need to apply for a visa (please note this when submitting your paper on the platform) will be prioritized in the weeks after the submission deadline in order to facilitate the visa application process. Presenting authors of accepted papers are required to become members of the IIPF and to confirm their presentation by registering by June 1, 2026. Payment of the annual membership fee ensures a reduced registration rate. For more information about IIPF membership please visit www.iipf.org/mbshp.

Authors who wish to be considered for the IIPF Young Economists Award, the IIPF Peggy and Richard Musgrave Prize (both for authors under 40 years), or the International Tax and Public Finance PhD Student Prize should indicate this when submitting papers for presentation. More information on the awards is available at www.iipf.org/awards.

Selected papers from the 2026 IIPF Congress will be published in a special issue of International Tax and Public Finance. To be considered for publication in this issue, papers must be submitted to the journal by September 15, 2026.

Keynote Speakers

Keynote Panel

The International Institute of Public Finance (IIPF) is the world organization of public finance economists, comprising approximately 600 members from over 50 countries. In an increasingly specialized academic field, the IIPF seeks to generate intellectual interchanges among public finance experts. The Institute’s annual congress is the main forum for its activities, which include organizing academic events, promoting the exchange of knowledge between academics and practitioners of all nationalities, and awarding prizes for outstanding academic achievements.

The congress also provides an opportunity for the IIPF governing bodies to convene (Board of Management, General Assembly of Members). The IIPF is currently administered by an Executive Committee consisting of President Wojciech Kopczuk (Columbia University, US) and two Vice Presidents,  Sara LaLumia (Williams College, US) and Nadine Riedel (University of Muenster, Germany). The legal and administrative seat of the non-profit organization IIPF is in Munich, Germany.
