We explore the design of self-financing tax-subsidy schemes to solve hold-up problems in environmental regulation. The announcement of the tax rate seems to be preferable to solve hold-up problems with respect to the investment in environmental R&D. In contrast, only the announcement of the...

The paper clarifies how sunk costs can lead a rational incumbent to innovate less than an entrant. It also demonstrates that competition among incumbents yields less adoption of new and more efficient production technology than competition which includes entrants. The results suggest that policy...

We analyze a patent race where the first innovator receives a time-dependent reward while all firms incur costs. When firms are identical, there is a unique, symmetric, mixed-strategy equilibrium that yields zero expected profits for all firms. Furthermore, the expected innovation time is an...
