existing |\knowledge. The |\difference |\between |\invention |\and |\innovation |\is |\that |- |\CORRECT |
ANSWERS |\✔✔1. |\invention |\refers |\to |\practical/technical |\recombination

  1. |\innovations |\create |\value |\from |\inventions
  2. |\innovation |\refers |\to |\economic/social |\recombination According |\to |\the |\combinatorial |\logic |\of |\invention |\and |\innovation |\that |

    ANSWERS |\✔✔exponential |\combinatorial |\possibilities |\create |\a |\large |
    risk |\of |\failure |(making |\it |\unlikely |\to |\find |\the |\right |\combination |

    risk |\among |\the |\public. According |\to |\the |\Schumpeterian |\distinction |\between |\invention |\and |
    innovation, |\why |\does |\it |\make |\sense |\for |\the |\private |\sector |(as |
    opposed |\to |\the |\public |\sector) |\to |\explore |\how |\to |\best |\come |\up |\with |
    innovations? |- |\CORRECT |\ANSWERS |\✔✔because |\the |\private |\sector |\is |
    part |\of |\the |\market |\dynamic, |\where |\price-driven |\supply |\and |\demand |
    dynamics |\help |\to |\shape |\what |\creates |\value |\for |\society.
