Following Arrow et al. (2003), this paper considers green national accounting when population is changing and instantaneous well-being depends not only on per capita consumption, but also population size. It is shown that welfare improvement can be indicated by an expanded “genuine savings indicator”, which also takes into account the total value of(More)
In manufacturing systems with large variety of products, small- to medium-size production runs are typically carried out according to the customers' orders. When the volume of a production run is small, the production system operates partially (or entirely) in the transient regime and the traditional steady-state analysis may become inapplicable. In this(More)
In this paper we discuss a general framework for analyzing labor supply behavior in the presence of complicated budgetand quantity constraints of which some are unobserved. The point of departure is that an individual’s labor supply decision can be considered as a choice from a set of discrete alternatives (jobs). These jobs are characterized by attributes(More)
It has often been claimed that firms’ compliance to environmental regulations is higher than predicted by standard theory, a result labeled the “Harrington paradox” in the literature. Enforcement data from Norway presented here appears, at first glance, to confirm this “stylized fact”: Firms are inspected less than once a year, detected violators are seldom(More)
This paper discusses the question of whether or not the high incidence of poverty among immigrants in Norway persists even after immigrants have been in the country for a long period, that is, after they have had the opportunity to integrate and adapt their skills to the expectations in their new home. While similar to traditional studies of wage(More)
With the fast development of Internet, web pages created by web spam which aimed at cheating the search engine and increasing rankings in the search results are prevailing. Web spam is a big problem for today's search engine; therefore it is necessary for search engines to be able to detect web spam during crawling. The web spam detection problem is viewed(More)
A user-based tourist attraction recommender system is developed in this paper. The recommender system is constructed as an online application which is capable of generating a personalized list of preference attractions for the tourist. Modern technologies of classical recommender system, such as collaborative filtering are considered to be effectively(More)
OBJECTIVE The objective of the present investigation was to investigate the role of integrin-linked kinase (ILK) in the gemcitabine-resistant lung cancer cell line A549 and explore the underlying mechanism. MATERIALS AND METHODS Gemcitabine-resistant A549 (A549/GemR) cell line was established by pulse-exposed to moderate concentration of gemcitabine(More)
Models of labor supply derived from stochastic utility representations and discretized sets of feasible hours of work have gained popularity because they are more practical than the standard approaches based on marginal calculus. In this paper we argue that practicality is not the only feature that can be addressed by means of stochastic choice theory. This(More)
