    Market failures associated with environmental pollution interact with market failures associated with the innovation and diffusion of new technologies. These combined market failures provide a strong rationale for a portfolio of public policies that foster emissions reduction as well as the development and adoption of environmentally beneficial technology. Both theory and empirical evidence suggest that the rate and direction of technological advance is influenced by market and regulatory incentives, and can be cost-effectively harnessed through the use of economic-incentive based policy. In the presence of weak or nonexistent environmental policies, investments in the development and diffusion of new environmentally beneficial technologies are very likely to be less than would be socially desirable. Positive knowledge and adoption spillovers and information problems can further weaken innovation incentives. While environmental technology policy is fraught with difficulties, a long-term view suggests a strategy of experimenting with policy approaches and systematically evaluating their success.

    This paper documents an analysis of English demographic change over the period 1573–1873. A simultaneous equations model is developed in order to test four alternative demographic theories—the constant equilibrium wage theory, the constant fertility theory, Lee's original (1973) synthesis theory, and a new, composite theory. Each is a special case of a general demographic model which provides both for exogenous technological change and for endogenous migration behavior. Two-stage least-squares estimation yields parameter estimates and test statistics, which provide evidence of the superiority of the composite theory of demographic change. By statistically affirming the composite theory of demographic change, this paper confirms that the mortality level played a dominant role in English demographic change during the preindustrial period. The analysis also provides support, however, for the classical notion that shifts in the labor demand function were a dominant cause of long-run population changes, subsequent to the beginning of British industrialization.
