Process and product R&D by a multiproduct monopolist

It is shown that the claim in Lambertini that a multiproductmonopolist's incentive for process R&D declines with thenumber of products it offers is incorrect. This incentive isin fact an increasing function of the number of products inhis model. I further extend the model of Lambertini to showthat whether or not process R&D incentive and the numberof varieties are positively related depends on the degree ofscope economies in process R&D. Product innovation promotesprocess R&D if the degree of such scope economies is high(as in Lambertini), and discourages it if the degree of scopeeconomies is low.

Demographic change and income inequality in the United States, 1976-1989

"The U.S. economy experienced significant increases in the degree of income inequality over the past two decades.... In this paper we consider the effects of race, age, female headship, and college education on the distribution of family income by developing a multivariate methodology that allows us to gauge the influence of one factor while holding other determinants of family incomes constant. Over the period studied we find that race had only a minor effect on the overall size distribution of income. Age had a somewhat greater effect than race. In contrast, the impact of female heads and college education were quite substantial. The multivariate estimates reveal that the effects of female heads and college education both increase the Gini to a much greater extent than the progressivity of federal income taxes decreases it. The effects of college education and female headed families on inequality have grown larger across time, while the influence of age has declined. We find that the effects of race on inequality have changed little over the 1976 to 1989 period."     

Slot Voorlezingen over de Economie,door Mr.P. A. Diepenhorst. III. Theorie. Tweede gedeelte

Das praktische Gesamturteil über das Problem ist deshalb so schwierig, weil die zunehmende Ungleichheit des Einkommens zunächst ein Instrument des individuellen und gesellschaftlichen Fortschrittes ist, von einem gewissen Punkte an aber freilich durch ihre Wirkung auf die Individuen und die Gemeinschaft versteinernd, depravierend, vergiften wirkt.
