The objective of this work is to design control strategies which optimize composition of production, technology stock and their rates in a nonlinear model of economic growth. The optimal control problem of R&D investment is formulated for a discounted utility function which correlates the amount of sales and production diversity. The maximum principle of Pontryagin is applied for designing opti...

T he two most striking historical features of aggregate output are its sustained long run growth and its recurrent fluctuations around this growth path. Real per capita GNP, consumption and investment in the United States during the postwar era are plotted in Figure 1. Both growth and deviations from the growth trend-often referred to as "business cycles"-are apparent in each series. Over horiz...

We study long-run trends in market hours of work and employment shifts across economic sectors driven by uneven TFP growth in market and home production. We focus on the structural transformation between agriculture, manufacturing and services and on the marketization of home production. The model can rationalize the observed falling or Ushaped pattern for aggregate hours, the shift from agricu...

Early applications of wilderness economic research demonstrated that the values of natural amenities and commodities produced from natural areas could be measured in commensurate terms. To the surprise of many, the economic values of wilderness protection often exceeded the potential commercial values that might result from resource extraction. Here, the concepts and tools used in the economic ...

I investigate cointegrating relationships such that, even though the long-run attractors are assumed to be linear, the dynamics of the equilibrium errors depends on the business cycle. I postulate a Markov-switching common stochastic trends model to study both the short-run responses to permanent shocks and the e/ects of recessions in the long-run growth. I apply these 0ndings to explore the sh...

Trends in the racial segregation of schools have been well documented, but less is known about trends in schools’ economic segregation. Residential segregation among neighborhoods by income has increased since 1970, but it is unclear whether segregation among schools or districts followed suit. We use multiple data sources to document trends from 1970 to 2010 in between-district residential seg...

TECHNOLOGY, ECONOMIC FACTORS, AND changes in the educational system are major factors in what is being termed a “revolution” in libraries. Does library user education have a place in that future? Some believe that libraries would be more effective concentrating their resources elsewhere. To put library instruction in perspective requires a look at its past and the status of programs in terms of...

Purpose: The aim of the study is to compare the perceived benefits of public libraries between five culturally different countries: Finland, Norway, the Netherlands, South Korea and the U.S. Design/methodology/approach: The data was based on representative samples of Finnish, Norwegian, Dutch, Korean and American adult library users. In Finland a mail survey was used and in other countries web ...
