Risk of failure
Takes a long time to materialize
Intangible output that leads to appropiability problems
While innovation pays off on average, profitability of specific projects is uncertain
+ innovation has low inside collateral value
Moral hazard: investors don't know if firm's are acting in the inventors' best interest
Adverse selection: investors don't know which are the best firms to invest to minimize risk
Because VC funds are underdevelopped

Research
Because it is more uncertain (takes more time to develop and it has a higher probability of getting no returns), the outcome is often tacit knowledge, so no tangible assets or property rights are obtained at the end.
Empirical evidence that, while routine R&D is not affected by a firm's creditworthiness, cutting-edge is, indicating that the latter is more sensitive to financial constraints.
R&D is typically financed with internal funds because external investors tend to prefer other kinds of investment since R&D investment is more risky and has a low inside collateral value. Furthermore, they face asymmetric information issues (moral hazard and adverse selection).
As a consequence, investors demand a higher rate of return for R&D projects.
High-tech start ups and small firms.
R&D subsidies and tax credits increase firm's IF -> less credit constrainted
Appropriability -> firms fail to fully capture the returns of their R&D investment -> private rate of return of R&D is lower than the public one -> not enough incentives to invest
Financing constraints -> uncertainity and assymetric information make investors demand higher return for R&D investments than other type of investments
