In 2022 he was recipient of Northwestern University's Nemmers Prize in Economics. Honored for his "fundamental contributions to the development of the field of empirical industrial organization as it is applied to the study of market power, prices, mergers and productivity.” Ariel’s research has focused on developing methods for empirically analyzing market responses to environmental and policy changes. This includes developing: i) demand systems that are capable of analyzing the impact of environmental changes (e.g. mergers) on prices, ii) methods capable of analyzing the impact of policy changes (e.g. deregulation) on productivity, and iii) models capable of following the impacts of these changes on the evolution of markets over time. He and his co-authors have applied these tools to the analysis of the auto, electricity, health care, and telecommunications equipment industries. Ariel also developed techniques for: analyzing the impacts of privately funded research and development activity, for constructing a more accurate Consumer Price Index, and for analyzing the impact of incentive schemes on the hospital allocations of doctors. Many of Ariel’s methodological contributions have been incorporated into the work of government agencies and private firms. Ariel has mentored over sixty doctoral students, many of whom are now leading researchers at prestigious universities. Additionally, he has done work for a number of consultancies, government agencies, and large firms. Ariel is married with two children and two granddaughters. They all enjoy hiking, jazz, and watching the NBA.
