Boom and Bust in the Venture Capital Industry and the Impact on Innovation Josh Lerner Harvard University and NBER
Extraordinary drop in venture activity…
… has triggered worries about consequences “Most venture capitalists are shelving the expensive change-the-world bets of the past few years.. The danger is that cutbacks will go too fast and too deep.” Business Week, 2001.
Agenda u Seeks to understand implications of venture investment collapse for innovation: Demystifying booms and busts in venture capital. Understanding implications for public policy. Exploring public policy consequences.
Basic elements u Not different from any other markets: Supply and demand! u Supply is willingness of investors to provide capital. Likely to increase with expected rate of return.
Supply Curve for Venture Capital Return Quantity
Basic elements (2) u Demand is supply of acceptable businesses. u Varies with return demanded by investors: The higher the return expectation, the fewer firms satisfy the test. u Together supply, demand will determine quantity Q, return R. Crude but useful! Can illustrate historical shifts from U.S.
Steady-State Level of Venture Capital Return Quantity S D R Q
Example 1: u Expansion of opportunity associated with diffusion of the Internet. u Can be seen as shift of demand curve outward. u Increase in VC funding, and rising returns: Predictions of inevitable decline misguided.

Example 2: 1979 u Prior to 1979, pension funds essentially prohibited from VC investing. u Policy shift allowed these investments, shifted demand curve out. u Led to decline in considerable growth, but decline in returns.

Example 3: 1957 u Sputnik launch led to two policy shifts: SBIC program, which made it easier to raise venture pools (supply). Boost in government high-tech procurement, which increased demand for VC. u Led to substantial increase in quantity, but little impact on returns.

Painful adjustments u So far, assumed smooth adjustment. u In actuality, may see under- or over- reaction: Dramatic swings in fundraising levels and returns. u How do these effects come about?
Level of fundraising
Level of returns
Rationales for stickiness u VC funds are raised for extended periods. u Investors shift targets only on occasion. u VC groups often limit rate of growth to avoid adjustment problems. u Even after decision is made, draw-downs and liquidations take many years. u Funds “self-liquidate”: must run faster in hot periods to stay even.
Consequences of stickiness u In long run, supply curve may be upward- sloping. u But in short run, may be nearly vertical. u Immediate consequence of demand shocks may be spike in returns, not volume.

Rationales for overshooting u Hard to assess promise of new technologies: Uncertainty is what created opportunity in first place! u Public markets provide very noisy--but highly visible--signals of industry promised: “Irrational exuberance.”
Consequences of overshooting u Public market, other signals may lead VCs to conclude that major demand shift: Actual shift may be far more modest. u Supply may swing out to perceived value, leading to: Surge in funding of investments. Poor returns.

Venture capital appears to spur innovation u Venture capital is well suited for funding high-risk innovative projects: Intensive scrutiny of business plans. Restrictions in preferred stock agreements. Staged financing. Board service and monitoring. Informal advice. Not surprising that dominant funding source.
Supporting evidence u Hellmann and Puri : Look at 170 Silicon Valley firms. Venture capital-backed firms seem more innovative on several measures. Unfortunately, hard to control for causality: Does VC spur innovation or does innovation spur VC?
Supporting evidence (2) u Kortum and Lerner  look at industry level: VC appears to have a strong positive effect: Even after controlling for corporate and government R&D spending. Use 1979 ERISA shift to address causality issues. In period, while VC <3% of corporate R&D, accounted for ~10% of innovation.
But is impact of market cycles as bad as it seems? u During “overshooting” periods, too similar companies funded at too high valuations: Biotech financing surge in early 1990s led to dozens of similar firms pursuing same approach to same disease. Mean pre-money value of VC-funded biotech firms in mid-1992 was $70MM. By 12/93, only 42 of 262 public biotechnology companies had a market capitalization above $70MM. Financial and social returns modest. Similar stories form Internet boom.
But is impact of market cycles as bad as it seems? (2) u Supporting evidence from regression analyses: Look at impact of venture capital on innovation in boom periods and others. Coefficient is about 15% lower during the years and industries with venture investments : Effect is strongly statistically significant. Effect widens when add controls for causality.
But is impact of market cycles as bad as it seems? (3) u Thus, while cycles in activity are dramatic, impact on innovation may be more modest. u Quality of companies funded during booms is often lower. Caution: if complete melt-down in fundraising, investments, could be very harmful.
Policy implications u “Public venture capital” programs have far too often added “fuel to the fire”: Concentrating on “hot sectors” in boom periods: May lead to “success stories,” but unlikely to boost innovation much. u Much better strategy is to focus on “out of favor” sectors and technologies: In-Q-Tel, SBIR provide models.
Policy implications (2) u More generally, may be best to focus on boosting demand for funds: Less emphasis on supply of capital. Possible efforts: Easing access to early-stage federally funded research. Tax incentives. u Less direct efforts likely to enjoy greatest success!
