This paper uses a tractable macroeconomic model with idiosyncratic human capital risk and incomplete markets to analyze the growth and welfare effects of business cycles. The analysis is based on the assumption that the elimination of business cycles eliminates the variation in idiosyncratic risk. The paper shows that a reduction in the variation in idiosyncratic risk decreases the ratio of phy...
The existing literature establishes possibilities of local determinacy and dynamic indeterminacy in continuous-time two-sector models of endogenous growth with social constant returns. The necessary and sufficient condition for local determinacy is that the factor intensity rankings of the two sectors are consistent in the private/physical and social/value sense. The necessary and sufficient co...
Traditional resource economics has been criticised for assuming too high elasticities of substitution, not observing material balance principles and relying too much on planner solutions to obtain long-term growth. By analysing a multi-sector R&Dbased endogenous growth model with exhaustible natural resources, labour, knowledge, and physical capital as inputs, the present paper addresses this c...
a r t i c l e i n f o In this paper, we analyze the social planner solution of an endogenous growth model with physical capital, human capital and R&D. The model incorporates three sources of inefficiency: monopolistic competition in the intermediate-goods sector, duplication externalities and spillovers in R&D. A complete stability analysis for the optimal growth problem of this model is provi...
This paper reviews the recent empirical literature on long-run growth to determine what factors influence growth in total factor productivity (TFP) and whether there are any channels of influence that should be added to standard models of long-run growth. Factors affecting productivity fall into three general categories: physical capital, human capital, and innovation (including other factors t...
Abstract Introduction: According to the psychological theories, the priority of adolescence is the acquisition of identity, which is influenced by physical, psychological, socio-cultural and spiritual factors of this period. The purpose of the present study is to investigate the role of agentic personality, social capital, moral intelligence and psychological capital in identity prediction. m...
This note makes two comments on recent NNS models. First, it disputes the way physical capital has been introduced into these models arguing that this leads to the dubious postulate that the cost of adjusting physical capital stock is an order of magnitude lower than the cost of changing prices. Second it warns against a possible logical inconsistency whereby calibrated NNS models are implicitl...
DEAR EDITOR, Should we control for overall health if we want to know whether higher social capital is associated with more physical activity? Is it reasonable to adjust for overall health if we want to explore the effect of a series of health behaviors on primary health‐care use? What if we want to understand how attitude about aging determines the trajectory of functional health over time? Wha...
Background and Aim: Social capital composed of networks, norms and values, which facilitates cooperation within and between groups to achieve mutual benefits and common goals. Social capital increases the benefits of investing in physical and human capital. In a society that favors more social capital, collaboration is easier. This study investigates the validity and reliability of a social cap...
in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
