This paper draws a comparison between social stability and chemical reaction process, and brings forward the concept of “social temperature” and “activation energy of social agent”. It is considered that social temperature turns out to be the macro symptom of social average energy, and its unceasing upclimbing roots in the energy accumulation of “inferiorization” process of social system; that ...

Over the past decade, Korean popular culture has spread infectiously throughout the world. The term, “Korean wave,” has been used to describe this rising popularity of Korean popular culture. The Korean wave exploded in the media across the world generating a ripple effect. The Korean government took full advantage of this national phenomenon and began aiding Korean media industries in exportin...

Human Capital Investment with Competitive Labor Search We study human capital accumulation in an environment of competitive search. Given that unemployed workers can default on their education loans, skilled individuals with a larger debt burden prefer riskier but better paid careers than is socially desirable. A higher level of employment risk in turn depresses the skill premium and the incent...

The building blocks of our model are bounded-rational actors with specific sets of endowments: ’entrepreneurial spirit’, human capital and venture capital. The entrepreneurial behavior to found a firm is triggered by the individuals’ endowments, their social network and the evaluation of the economic situation. Bandwagon effects occur when high growth rates in emerging markets increase firm ent...

We consider spherically symmetric static solutions of the Einstein equations with a positive cosmological constant Λ, which are regular at the centre, and we investigate the influence of Λ on the bound of M/R, where M is the ADM mass and R is the area radius of the boundary of the static object. We find that for any solution which satisfies the energy condition p+ 2p⊥ ≤ ρ, where p ≥ 0 and p⊥ ar...

This paper develops a uni...ed theory for the dynamic implications of income inequality on the process of development. The proposed theory argues that the replacement of physical capital accumulation by human capital accumulation as a prime engine of economic growth has changed the qualitative impact of inequality on the process of development. In early stages of industrialization as physical c...

We analyze the interaction between risk sharing and capital accumulation in a stochastic OLG model with production. We give a complete characterization of interim Pareto optimality. Our characterization also subsumes equilibria with a PAYG social security system. In a competitive equilibrium interim Pareto optimality is equivalent to intergenerational exchange e¢ciency, which in turn implies dy...

Modern culture, based on disinhibition of cultural trends and on heterodirection, is promoting openmindedness attitudes towards ethnic diversity, but on the other hand also new forms of social representations of the foreigner. Social representation is situated between the psychic field and the social one; it is the representation of oneself and of the other one, hanging between social categorie...

Since the 2000s, social networks have grown spectacularly until they are now regarded as indispensable and introduced as a daily practice of millions of users. Enterprises have become aware of the need and the importance of these collaborative tools, and the concept of Enterprise Social Network (ESN) has now emerged. As such, OpenPaaS is an innovative ESN that aims at facilitating inter-organiz...

Homophily, the tendency for similar actors to be connected at a higher rate than dissimilar actors, is a pervasive social fact. In this article, we examine changes over a 20-year period in two types of homophily—the actual level of contact between people in different social categories and the level of contact relative to chance. We use data from the 1985 and 2004 General Social Surveys to ask w...
