Con questo articolo si intende offrire una rassegna critica del dibattito in corso da più di un decennio sul concetto di capitale sociale. Gli studi considerati sono suddivisi in base all’aspetto della struttura sociale cui di volta in volta viene accordata maggiore enfasi. La rassegna si...

The paper uses micro-level data obtained from surveying informal and formal small textile producers in Bolivia to estimate the economic returns to social capital. Social capital is defined as being linked to other individuals. The paper studies forms of social links that vary with respect to...

Many emerging or transition economies lack institutional arrangements (like ISO certification) to credibly signal product quality. The absence of such institutions leads to low levels of market activity with poor quality products on sale. In this paper, we use a dynamic framework with asymmetric...

Agent-based computational economics (ACE) is the computational study of economies modelled as evolving decentralized systems of autonomous interacting agents. A key focus of ACE research is understanding how global regularities arise from the bottom up, through the repeated local interactions of...

The recent reform of the federal welfare system is meant to encourage recipients to leave welfare and enter the workforce. If the reform is successful there are likely to be effects felt throughout the low-- skilled end of the labor market. As former welfare recipients enter the labor market,...

We develop a model where agents obtain information about job opportunities through an explicitly modeled network of social contacts. We show that an improvement in the employment status of either an agent's direct or indirect contacts leads to an increase in the agent's employment probability...

Es elevada la dependencia entre la industria maquiladora de exportación de México y el desempeño de la economía de Estados Unidos; sin embargo, son relativamente escasas las investigaciones que dan cuenta del comportamiento de otras industrias y su relación con el mercado del país...

This study reports on computational experiments for an agent-based labor market model with adaptive choice and refusal of worksite partners and with endogenously evolving worksite behaviors. Two treatment factors are experimentally varied: market structure; and ex ante capacity constraints on...

n the late 1990s, Knowledge Management (KM) and Communities of Practice (CoPs) seemed inseparable. CoPs appeared to offer the key to reversing the failure of some of the earlier technologically based attempts to manage knowledge. However, the original CoP concept was built around a very...
