This year’s prize in economic sciences uses microfoundations to deliver macro insights.

TOMORROW Tues 15 Sept at 10 am (CEST) we are thrilled to welcome Fabian Waldinger from Ludwig Maximilian University of Munich who will present his paper "Dictators, Democracies, and Discoveries: Political Institutions and the Creation of Knowledge". bit.ly/4j2lwTU

What drives productivity growth, how should we measure automation, and why does inflation remain persistent? These are the questions explored in Chek Yin Choi's doctoral thesis, Input Market, Automation, and Inflation: Essays in Macroeconomics, at Stockholm University. 🧵👇 www.su.se/english/divi...

Together, the three essays highlight how firms' everyday decisions, from choosing suppliers and investing in technology to deciding when to change prices, can have significant effects on the wider economy. #Economics #Macroeconomics #Research #PhD #Inflation #Automation

Measuring automation is not straightforward. Using detailed Swedish data, Chek finds that conclusions about automation's effects depend heavily on how automation is defined. Looking only at industrial robots may miss important effects from other technologies.

Why does inflation persist? The thesis shows that inflation can remain elevated because firms do not adjust prices immediately when conditions change. Their pricing decisions create inflation dynamics that can last long after the initial shock.

Finding suppliers matters. The thesis shows that easier access to suppliers can boost productivity by helping firms find better and cheaper inputs. But these gains are not evenly distributed: the most productive firms tend to benefit the most, contributing to greater market concentration.

Bottom line: • Too much concentration can slow growth • Firm-level behavior drives big economic outcomes • Inflation persistence can come from how firms set prices 👉 What happens inside firms matters for the whole economy

A few firms can shape entire sectors Even small differences between firms can create lasting gaps in growth. 👉 Large firms have outsized influence 👉 Market structure alone can explain persistent differences across industries

Why inflation sticks around Firms don’t change prices instantly—they wait. Some adjust quickly, others delay → creating gradual, persistent inflation Inflation depends partly on its own past because of this staggered behavior.

Market concentration can drag on growth When a few firms dominate an industry, resources are less likely to move to the most productive firms. Result: • +10pp concentration → −3pp productivity growth • Up to −13pp in more distorted markets
