With the social context of collaborative networks becoming increasingly important, research has broadened the traditional concept of competitiveness to include and emphasize ‘soft’ elements, like social capital. The social capital concept can be attained in two different contexts: intra and inter-groups. The objective of this study is to identify inter-organizational social capital elements and...

We present a growth model in which investment in physical capital shows positive externalities which build up knowledge capital. A prerequisite for these spillovers to take place is that a country devotes time to education. Externalities associated with investment need education to raise the stock of knowledge capital. Analyzing the competitive economy we demonstrate that the model may explain ...

This paper studies optimal pay-as-you-go social security with positive bequests and endogenous fertility. With an investment externality, a competitive solution without social security suffers from under-investment in capital and over-reproduction of population. We show that social security can improve welfare by reducing fertility and increasing capital intensity. We also illustrate numericall...

This paper opens a new perspective from which one can explain the presence of government intervention in education even in the absence of human capital externality. It argues that consumption externalities can provide rationale for government intervention in education. Within the context of overlapping generations economy, it has also been shown that competitive equilibrium either underaccumula...

measurement of magnitude and frequency of the voltage flicker is very important for monitoring andcontrolling voltage flicker efficiently to improve the network power quality. this paper presents twonew methods for measurement of flicker signal parameters using shuffled frog leaping algorithm(sfla) and imperialist competitive algorithm (ica). this paper estimates fundamental voltage andflicker ...

We extend the shallow lake model by adding the capital stock of an industry. A government can mitigate the effects of pollution arising from industrial activities by imposing the requirement to abate emissions. Within this framework two scenarios are examined: in the social optimal benchmark, the social planner optimally allocates investment. In the competitive equilibrium, market forces determ...
