    biodiversity
    the full spectrum of animal and plant genetic material
    command-and-control regulation
    laws that specify allowable quantities of pollution and that also may detail which pollution-control technologies must be used
    externality
    a market exchange that affects a third party who is outside or “external” to the exchange; sometimes called a “spillover”
    free rider

    When the market on its own does not allocate resources efficiently in a way that balances social costs and benefits; externalities are one example of a market failure

    negative externality
    a situation where a third party, outside the transaction, suffers from a market transaction by others
    nonexcludable

    property rights
    the legal rights of ownership on which others are not allowed to infringe without paying compensation
    public good
    good that is nonexcludable and nonrivalrous, and thus is difficult for market producers to sell to individual consumers
    social benefits
    the dollar value of all benefits of a new product or process invented by a company that can be captured by other firms and by society as a whole
    social costs
    costs that include both the private costs incurred by firms and also additional costs incurred by third parties outside the production process, like costs of pollution
    social rate of return
    when the estimated rates of return go primarily to society; for example, providing free education
