💬 [E7149] Shiller proposes GDP-linked government debt as an innovation that could prevent sovereign debt crises. Such instruments would automatically reduce government obligations during economic downturns as GDP falls, cushioning refinancing problems. He argues this could have likely prevented severe crises like Europe's sovereign debt crisis starting in 2009.

💬 [E7150] Shiller notes that inflation-indexed bonds have grown over the last half century but achieved only incomplete success globally. He advocates for creating inflation-indexed units of account to help people overcome money illusion and design better contracts around real outcomes, which would enhance adoption and improve risk-sharing across the physical and financial economy.

💬 [E7148] Shiller argues that well-designed financial innovations such as housing futures, GDP-linked debt, and occupational income hedging could reduce market vulnerability to bubbles and crashes. Had housing futures existed before 2008, they would have encouraged hedging and reduced the leveraged undiversified positions that sent 15+ million U.S. mortgages underwater, mitigating the severity of the financial crisis.

🟢 [E7152] Shiller advocates for expanding risk-sharing capabilities through new financial instruments including housing futures, occupational income markets, and perpetual futures. These innovations would allow individuals to hedge livelihood risks and diversify away from concentrated leveraged positions (e.g., single-home ownership), fundamentally improving household-level portfolio construction and income protection.

🟢 [E7151] Shiller argues that creative reinventions in the kinds of risks traded, changes in psychological framing, and altered social relations with business partners can make financial markets structurally less vulnerable to excesses and crashes. He maintains that no economic system other than financial capitalism has brought comparable prosperity, and further expansion with proper innovation and regulation can improve resilience across economic cycles.
