Taxing Matters

Source details

Research traces the effect of taxation on inventors in the United States "all the way back to the 1930s."
Key empirical findings:
- Taxation has a negative effect on innovation measured by both quantity (number of patents) and location.
- States with higher personal—and especially higher corporate income taxes—lost out to lower-income-tax states in terms of innovation.
- Superstar inventors are highly mobile and sensitive to taxes; migration effects are powerful for highly qualified inventors.
Important qualifiers:
- Taxation exists to raise revenue for public spending; higher taxes do not automatically eradicate innovation when spent on amenities and research infrastructure.
- Places with many existing inventors or strong research infrastructure can sustain higher taxes without losing all innovative capacity (example cited: California).

Principal policy conclusion:
- Because taxes are needed for many public purposes, it is important to dampen their negative economic effects by how revenues are used.
Specific policy guidance:
- Prioritize revenues that foster research and innovation infrastructure and amenities that make a location attractive to innovators.
- Design tax systems mindful of both incentive effects on innovators and the revenue needs for public goods that support innovation.

Methodological approach:
- The Social Economics Lab uses surveys combined with experimental variation (some respondents see different information) to uncover beliefs, perceptions, and reasoning that administrative data cannot reveal.
- The approach creates "big data" on people’s minds and allows quantitative analysis of patterns and causal effects.

Climate policy example:
- Economic theory favors taxation of pollution over outright bans as more efficient, but survey evidence shows people often consider bans fairer because of equity concerns—the perception that "the rich can simply pay to pollute while others cannot."
Zero-sum thinking:
- Defined as the belief that gains for some must come at the expense of others (limited amount of good).
- Empirical patterns:
- Zero-sum thinking is much more prevalent among younger people in the US and other rich countries.
- In emerging market economies, younger generations are less zero-sum than older generations due to higher growth and mobility.
- Individual experience matters: those from families with upward mobility are less likely to be zero-sum.
- Political implications:
- Zero-sum thinking is not strongly partisan—it's "evenly distributed across both sides of the political divide"—but it explains within-party variation in policy views.
- People who are more zero-sum favor more government intervention and more redistribution, driven by the belief that gains of the rich come at the expense of the poor.
- The prevalence of zero-sum thinking among younger generations may influence future policy debates and preferences.
