This paper investigates the spending and current-account effects of terms-of-trade shifts in a model where households maximize utility over an infinite planning period. In the framework developed here, an economy specialized in production must experience a fall in aggregate spending and a current surplus as a result of an unanticipated, permanent worsening in its terms of trade. The paper's model thus provides a setting in which the current-account deficit predicted by Laursen and Metzier, Harberger, and others fails to materialize.

The notion that the cost of increasing family size depends upon the level of expenditures or investment per child (child quality), formalized in Becker and Lewis (1973) and Willis (1973), provides a rationale for the contemporaneous inter-country negative correlation between the schooling attainment of young persons and birth rates as well as the trends in these variables over time in developed countries during their demographic transition.A sufficient condition for fertility to fall and, say, schooling to rise as development proceeds in this framework is that the shadow-price constant income effect on quality per child 1 exceed that on numbers of children.Such an explanation, however, would appear :..o be of little value for those who hold that population growth itself impedes economic development (e.g., Coale and Hoover (1958)).From this perspective, the compensated substitution.implications of the theory are of concern, whereby price interventions which impinge on family size decisions can be used to accelerate pe~-capita income.The chief focus of policies aimed at reducing fertility in the absence of income growth appears to be on altering the "own" price of children through lowering information costs associated with contraceptive methdos in order to take advantage of recent innovations in birth control technolo~y.In this paper, we examine both theoretically and empirically the natalist impact of two alternative potential policies--reductions in the price of schooling and tech~ological innovation in the agricltural context--based on a rural household model in which (school) investments per child influence the cost of children as in the Becker-Lewis framework and in which the returns to schooling rise in a dynamic environment as a consequence of the allocative effect of education (Welch, 1970;Schultz, 1975).I show that, as a consequence of the "quantity-quality" interaction, reductions in the direct costs of schooling may raise fertility levels even if child schooling and the quantity of children are substitutes as conventionally defined and even if (observed) income effects are not positive.2,:. w

This paper analyzes the effect of commodity price stabilization on producers and consumers, both in the short run, and in the long run, when producers have adjusted their production decisions to take account of the change in the price distribution. We derive conditions under which (a) both producers and consumers may be better off; and (b) both producers and consumers may be worse off. Moreover, we show that the long-run effects may differ not only quantitatively but also qualitatively from the short-run effects. The anomalous results may occur even with reasonable assumptions concerning production functions and utility functions of producers and consumers.
