This paper presents a dynamic model of the firm, where the firm can exert influence on demand by setting the price and by
controlling the quality index. Assuming profit maximization, it is shown by means of the Hopf Bifurcation theorem that persistent
oscillations of the variables may occur if there is positive growth at the steady state together with a high discount rate.
Oscillations may also occur if the influence of an additional unit of the quality index on demand and price is sufficiently
large, thus yielding a special version of the product life cycle. A numerical example is used in order to illustrate the results
derived in the general framework.

A stochastic model is developed to estimate the expected social costs with and without a family planning program provided to a population. By examining the tradeoffs between the program costs and the costs of unwanted pregnancies, it is possible to estimate the costs and benefits of alternative family planning programs. Several extensions of the basic model are presented which permit the selection of optimal treatment variables for administration of a particular program as well as determining the long range effects of a particular family planning program. 相似文献

The hypothesis that depressions trigger innovations is examined first on theoretical grounds, and then with a random sample of 120 innovations. Radical product innovations, the alleged basis for new ‘Schumpeterian’ industries, indeed cluster around the 1930s crisis, but are closely associated with the less severely hit modern industries. Process innovations and less radical product changes are associated more with periods of prosperity. The final section considers whether new ‘Schumpeterian’ industries are a precondition for, or the result of, economic upswings. 相似文献

Macro-economic determinants of consumer price knowledge: A meta-analysis of four decades of research
Hooman Estelami Donald R. Lehmann Alfred C. Holden 《International Journal of Research in Marketing》2001,18(4)
For the past four decades, dozens of researchers have studied consumer price knowledge, often with disagreements on the extent of consumer' ignorance about prices. While some of these disagreements have been attributed to research design variations among studies, no inquiry has yet been made on the role of the economic environment on consumer price knowledge. Nevertheless, environmental factors such as interest rates, unemployment, and economic growth may significantly influence consumers' knowledge of prices. Certain economic environments may therefore provide marketers with the ability to utilize pricing tactics which rely on limitations in consumers' knowledge of product prices. Using a meta-analytic framework, this paper synthesizes the results of 297 previous price knowledge studies to document the effects of inflation, unemployment, GDP growth, interest rates, country of study, and passage of time on consumer price knowledge. The meta-analysis results demonstrate that economic factors have considerable influence on explaining variations in consumer price knowledge. Managerial and public policy implications of the findings in light of turbulent economic environments are discussed. 相似文献

Is there a contradiction between international competitiveness and the central principles of the welfare state? The following article examines both the negative and the positive ways in which welfare statism can affect a country’s ability to compete on international markets. 相似文献
