CBA Economics Roundtable 2026: Negotiation and Market Power in Antitrust Enforcement
Presented by the CBA Competition Law and Foreign Investment Review Section
Wednesday, May 13, 2026 | 10:00 AM–3:45 PM ET
Hybrid In-Person or Online
Negotiation is a pervasive feature of many markets, influencing both price and non-price dimensions of products and services. Over the past decade, antitrust analysis has increasingly adopted modern techniques to study markets where outcomes are shaped by bargaining between parties. In today’s environment—marked by heightened attention to labour market competition and recent frictions in collective bargaining—these approaches are particularly relevant for understanding negotiations between employers and employees.
This year’s Roundtable will examine how economic models of bargaining are applied in antitrust enforcement, with practical implications for merger review, conduct investigations, and labour market cases. It will provide practitioners with a deeper understanding of how these models shape enforcement approaches and highlight emerging issues in markets where prices and terms are negotiated.

Lunch & Keynote Address – Acquihiring for Monopsony Power (30 minutes)
Dr. Heski Bar-Isaac will explore the economics of “acquihiring” and its implications for competition policy. Drawing on his recent research, he will explain how acquisitions aimed at securing specialized talent can reduce competition in labor markets and create monopsony power. The presentation will examine why firms may prefer acquihiring over direct hiring, how this strategy can suppress wages and harm workers, and under what conditions these acquisitions may lead to inefficient outcomes. Dr. Bar-Isaac will also discuss the enforcement challenges this behavior poses for merger review and labour market cases, offering insights into how antitrust frameworks can adapt to address these emerging concerns.
Speaker: Dr. Heski Bar-Isaac, Distinguished Professor of Economics and Finance, Rotman School of Management, University of Toronto
