What Does Economic Power Mean?
A genealogy of the distinction between economic power and market power, built from cases where one exists without the other.
Work in progressCompetition, regulation and digital markets
Professor and lawyer. Born in southern Brazil, based in São Paulo, son of Francisco and Cleys, married to Rafael, dog father to Pudim, gay and an advocate.
I keep several projects running at once: events, courses, reading groups, research, mentoring. I also speak at events and write expert opinions. I recently went back to studying the transverse flute.
Before law I started degrees in advertising and in library science, and finished neither. I then spent six years as in-house counsel at Abbott, in Brazil and in the United States. From advertising I kept a concern with form and presentation that never left me. From in-house practice, the habit of looking at law from the standpoint of those who decide.
This site gathers what I teach and what I research, including what is still half finished. I publish slides, texts and recordings in open access because legal knowledge circulates less than it could. If something here is useful to you, or if you disagree with it, write to me.
Note Personal and independent website. Everything here is my own responsibility and does not represent the position of ESPM, of my law firm or of any other institution. Since I practise law, I write about matters I also work on professionally; whenever a text relates to a case or client of mine, that is stated in the text itself.
What is on the table at the moment: the text I am writing, the research under way and what is coming next.

2026 to 2027Undergraduate courses at the ESPM Law School this term.
2026Professor and lawyer. I split my time between teaching, research and practice in economic, competition and regulatory law, with a focus on digital markets.
I grew up in the house of a teacher and an engineer, where studying occupied the centre. Being a professor comes from there, and the classroom is still where I work best.
I started advertising before law, and started library science too; I finished neither. What stayed with me from those years is a constant preoccupation with form, design and presentation. Not that I think I write or speak clearly. It is more that the question never leaves me alone, in the classroom, in a legal opinion and in the events I organise.
I read law at UFRGS, spent a year at Giessen on the Unibral programme, took an LL.M. at Yale, where I was an editor of the Yale Journal on Regulation, and completed a doctorate in Commercial Law at the University of São Paulo, with research at the Max Planck Institute in Hamburg. I worked in the office of the president of CADE, the Brazilian competition authority, at the Bundeskartellamt in Germany, at competition practices in private firms, and for six years as in-house counsel at Abbott, in Brazil and in Chicago. In 2025 I served as a UNDP consultant to CADE on the public hearing regarding the iOS and Android digital ecosystems.
Six years of in-house practice left me with a research conviction. The legal department is little studied in competition law: academia rarely takes it as an object of study, and outside counsel tends to treat it as a client before treating it as a technical interlocutor. Yet it is there, inside the economic agent, that competition decisions take shape, long before anything becomes a case. I treat the subject as a technical problem, in the classroom, in the programmes I direct and in my research.
Today I am a partner at Berardo Lilla Becker Segala Daniel Advogados, working in competition and digital markets, alongside the firm's corporate, contracts, litigation and regulatory practices. The partnership leaves me the schedule to teach, research and supervise.
Teaching is the centre of what I do. I prefer small classes, where every student is known by name, with a real case under discussion and room to disagree. I teach at undergraduate and postgraduate level and design executive programmes for practitioners.
Undergraduate courses at the Law School. I also teach in postgraduate and specialisation programmes.
Market structure, merger control, unilateral conduct and cartels, built on CADE case law.
Agencies, regulatory design, market failures and the line between regulating and competing.
The constitutional economic order, economic power and the legal instruments of state intervention.
Incentives, transaction costs and economic method applied to concrete legal problems.
Slides from classes and talks in PDF, free for anyone studying or teaching, with attribution. I publish what is mine and what I am free to release: material from commissioned programmes generally belongs to the institution. If you are looking for something that is not here, write to me.
Executive programmes I designed and led, open to practitioners in the field.
Training in competition law with an emphasis on a critical reading of its normative, institutional and economic foundations, in Brazil and in comparative perspective.
A programme aimed at in-house practice and digital markets, built around concrete cases and the intersections between competition, innovation, ESG and big data.
The full list of courses, supervision and examination boards is on my Lattes CV.
I work with law and economics and with empirical method, and in groups whenever possible. Much of what legal scholarship takes for granted has never been tested against data, and that is usually where I come in. One question that occupies me is the in-house one: how competition decisions take shape inside the economic agent, before there is ever a case. The agenda I want to develop now is that of healthcare markets.

A long-running research project on how antitrust adapts to platform markets, and the basis for much of what I publish on the subject.
A genealogy of the distinction between economic power and market power, built from cases where one exists without the other.
On the design of leniency programmes and the incentives they actually produce.
What I do outside the classroom: the events I organise and speak at, long-running projects, mentoring, student competitions, talks and expert opinions. Much of it comes from wanting to bring the people inside companies closer to the technical and academic debate.
Events I have organised or directed, and gatherings I was invited to speak at. Each poster links to the event page.
The first group of its kind at the school devoted to Asian legal systems, created to break through the Eurocentrism of the material available to undergraduates.
A free legal clinic for non-profits and small businesses without access to private counsel. I founded it in 2010 and it has been running for more than fifteen years.
A student think tank on public policy, with workshops for secondary school pupils and an annual conference. I conceived and organised the first two editions of the Winter Course in Economic Analysis of Law, in 2010 and 2011, at the UFRGS Law School.
Mentoring is an important part of what I do. I work through three channels in academic and professional settings, and all of them take newcomers. There is also the mentoring programme of the Frente Jurídica LGBTQIAPN+, which appears under diversity.
I take part in and encourage student competitions. It is the format that brings students closest to practice. The learning lies above all in the preparation.
I speak at events on competition law, digital markets, regulation and investment funds, at law firms, companies, associations and universities. I also write expert opinions on competition and regulatory matters. Invitations through the contact details below.

Interviews, appearances and quotes in the press.
Recordings of panels, debates, interviews and open classes. Each thumbnail opens the video right here, without leaving the page; for long events, it starts at my segment.
For almost ten years I have worked on diversity within the legal profession. Who gets to speak on a panel, who gets hired by a firm and who stays there are questions of market structure, and that is how I treat the subject.
I took part in setting up the firm's diversity programme, the first formal structure of its kind where I worked.
I created the LGBTQIAPN+ employee resource group of the Brazilian affiliate from scratch.
Expanding the network across the region, coordinating between affiliates.
Leading the network worldwide, from Chicago.
A non-profit organisation of LGBTQIAPN+ lawyers, today with more than five hundred members and a steady presence in São Paulo's legal community. It runs a mentoring programme for people starting out in the profession.
Applying the Guide on Diversity and Training for Events and Seminars, including in the panel selection rules of the International Competition Law Seminar.
I have spoken about diversity at law firms and companies, and I advise on setting up diversity initiatives: designing employee resource groups, targets, internal policies and criteria for events. I like bringing economic and technical perspective into this debate, rather than treating it as rhetoric alone. For invitations, the contact details are at the end of the page.
