(7) There is a valid “great stagnation” worry, but it is overwhelmingly one of institution design rather than of innovation exhaustion.And here we reach what I regard as the big issue. In the future we are going to want to spend a greater share of our incomes and attention in areas where the market system works less well: information goods, public goods, increasing-returns goods, pensions, health care, education. The market works less well in these areas. But our alternative modes of collective organization, product take some bureaucracy, not exactly cover themselves with glory in these areas either. Thus I suspect that not innovation exhaustion but rather institution design will be our big problem in keeping the pace of true economic growth going into the long-run future.
