Perpetual Growth Machine, Housing, and AI's Productivity

In this episode, William Blair Global Strategist Olga Bitel joins us to unpack her “Perpetual Growth Machine” framework and what it means for investors navigating AI, tariffs, inflation volatility, market concentration, and a shifting global order. We dig into why growth often emerges from solving problems, how monopolies can stunt future innovation, where AI’s productivity dividends could accrue, and why she sees the next decade’s best opportunities outside the United States. Olga also walks through the risks she’s watching, why facts change faster than narratives, and practical ways to connect top-down insights with bottom-up research.

Topics covered

• The Perpetual Growth Machine: why needs spark innovation and growth, and how investors can spot it early

• Why monopolies look great to investors but hurt long-term growth and innovation

• AI as a general purpose technology and the scale of potential productivity savings

• Housing affordability, incomes, and policy bottlenecks through the PGM lens

• How firms are actually adopting AI and how faster data changes research cadence

• Europe’s defense build-out and the rise of national champions and small-cap innovators

• Interpreting market concentration and what it signals about competition

• Inflation oscillation, policy mix, and why the Fed’s tools have limits

• Tariffs as a regressive tax and how costs pass through to consumers over time

• US exceptionalism narrowing and why ex-US markets may lead in the coming cycle

• The Draghi report and tearing down barriers inside the EU single market

• Comparing late-1990s tech to today’s AI build-out and who the next leaders may be

• Growth vs. value: focusing on sustained profit inflections, not cheapness alone

• Using stakeholder analysis to link macro themes to bottom-up stock work

• Biggest opportunities: Japan, Korea, Europe, select emerging markets, and parts of the Middle East

• Biggest risk: a breakdown in the global order amid US-China tensions

• Closing lessons: stay curious, stay nimble, question narratives, track the facts
