We study a dynamic economy in which heterogeneous entrepreneurs invest in either generic or innovative technologies, the latter relying on intangible, firm-specific assets whose payoffs are realized through learning or experimentation (e.g., know-how, R&D). A key friction is that, to finance investment, entrepreneurs can pledge assets but not cash flows. We show that innovative technologies can relax financing constraints by increasing the value of continuation relative to default, thereby enabling borrowing against future cash flows. Technology choice is non-monotonic in productivity: low-productivity entrepreneurs innovate-to-experiment and delay investment, intermediate types adopt generic technologies, and high-productivity entrepreneurs innovate-to-scale and relax financial constraints. In equilibrium, financial frictions distort both the allocation of capital and the choice of technology, leading to insufficient experimentation. The model helps us understand how innovation is adopted across firms and economies and has novel policy implications.
