in this paper, i investigated the determinants of financial development with emphasis on social capital. first, i explain the relationship between financial development and its determinants, then estimate the model with gregory–hansen (1996) and johansen-juselious cointegration techniques in i.r. of iran (1971-2006). the results showed that, inflation and decline in social capital and weak prop...

A stable government is by definition not dominated by any other government. However, it may happen that all governments are dominated. In graph-theoretic terms this means that the dominance graph does not possess a source. In this paper we are able to deal with this case by a clever combination of notions from different fields, such as relational algebra, graph theory and social choice theory, ...

This paper brings together analyses of two-way flow Strict Nash networks under exclusive player heterogeneity assumption and exclusive partner heterogeneity assumption. This is achieved through examining how the interactions between these two assumptions influence important properties of Strict Nash networks. Built upon the findings of Billand et al (2011) and Galleotti et al (2006), which assu...

We present a model of network formation where entering nodes find other nodes to link to both completely at random and through search of the neighborhoods of these randomly met nodes. We show that this model exhibits the full spectrum of features that have been found to characterize large socially generated networks. Moreover, we derive the distribution of degree (number of links) across nodes,...

O ne of the effective strategies for economic development of clusters is the conduct of networking activities by cluster members. Indeed, the majority of cluster members are micro and small enterprises, so, should attempt to overcome their inherent constraints and influence the market through networking activities. In addition, these enterprises lack an intra-firm research and develo...

this paper aims to estimate a model of demand for health insurance and medical care in iran in the presence of the heterogeneous and latent health status of individual; moreover it tests the asymmetry of information in the health insurance industry of iran. our dataset consists of whole family budget survey of 2006. the parameters of model are estimated by g.m.m method and the model used in thi...

in this paper, the effect of financial liberalization on household’s budget liquidity constraint is analyzed with the use of an error correction model. financial liberalization will decline liquidity constraint, with expanding means of making future incomes available for present consumption. here a financial liberalization index for iran is defined using principal component analysis technique, ...

We examine the role of macroeconomic ‡uctuations, asset market liquidity, and network structure in determining contagion and aggregate losses in a …nancial system. Systemic instability is explored in a …nancial network comprising three distinct, but interconnected, sets of agents – domestic banks, international …nancial institutions, and …rms. Calibrating the model to advanced country banking s...

We study how social networks change as a result of an exogenous expansion in formal financial access and show how to estimate the effects of these changes on household outcomes. We use a unique household panel dataset that contains detailed information on the network of informal financial transactions before and after a field experiment that randomized access to savings accounts in Nepal. First...

The influence of social networks on housing tenure choice remains conspicuously unexplored despite the fact that social networks are crucial in information dissemination. Social networks can encourage the attainment and retention of homeownership by channeling important knowledge and information regarding household finance, wealth management, home maintenance, etc. Social networks also provide ...
