research and development - depends on fertility and appropriability
- spending on research leads to new ideas >> not the same as spending on machines or labor
- fertility - how R&D spending results to new ideas/products
- depends on interaction between basic research (searching for general principles/results) and applied research (applying results to specific uses)
- takes time to exploit full potential of major discoveries
- appropriability - how much firms can profit from own R&D
- too much research fertility >> doesn't mean much to discover new things >> little payoff >> small appropriability
- protection (patents) - gives advantage to firm who makes the discover first
- too much protection >> R&D stalls >> difficult for other firms to build on past discoveries
- too little protection >> firms don't have as much incentive to keep trying
- less technologically advanced >> usually poorer patent projection >> typically more users than producers of new technology
