One policy making issue that needs to be addressed more effectively through an intergovernmental and participatory approach is entrepreneurship policy. Entrepreneurship is an area where interdependencies are very high, and the establishment of collaborative relationships such as networks is vital. Therefore, a network approach in the entrepreneurial policy-making process, which leads to the involvement of key stakeholders and entrepreneurs, will lead to higher legitimacy and effectiveness of policies. The purpose of the research is to validate and design a suitable model for policy networks in the field of entrepreneurship. Qualitative data analysis was conducted through theme analysis; and the quantitative data through the structural equations. After designing the conceptual model, the research questionnaire with dimensions was distributed among 240 experts and managers of the Ministry of Cooperatives, Labor and Social Welfare. Reliability of the questionnaire was verified using Cronbach's alpha and composite Reliability Coefficient (CR), and its validity was confirmed by Convergent Validity and Convergent Validity (AVE) methods. Finally, 24 components were identified in four branches of necessity, structural, behavioral and background. The findings show that, it is essential for the Ministry of Cooperatives, Labor and Social Welfare to focus on the role and importance of these entrepreneurs in order to develop the field of entrepreneurship, and to consider the network thinking in policy making as a substitute for hierarchical thinking.

Granular residual is created in the banking network when there are a few large banks with many small banks. In this case, the effect of the shocks on each bank not lost in total that can lead to macro-economic consequences. The transmission of monetary policy through change in bank facilities is one of the key mechanisms affecting monetary policies. The power of transmission of monetary policy mechanism is highly dependent on the specific characteristics of the banking network. Thus, the importance of granular residual and considering it on transmission of monetary policy in the banking network is important. The purpose of the present study is the effect of granular residual in Iran's banking network on the transmission of monetary policy through lending channel. Indeed, the granular residual was imported in this study as a independent variable that can effect on bank facilities and lending channel. Therefore, in the present study, the balance sheet data of 32 banks from the banking network for the period 2001-2014 were used.Themodel used in this study was estimated through the Generalized Method of Moments (GMM). The results showed that in the first, according to available theories in relation to the granular residual and conducting relevant empirical analyses, the presence of granular residual in Iran's banking network is confirmed. Also as expected, granular residual has a positive and significant effect on Iran's banking network facilities and the transmission of monetary policy through lending channel is weakened by increasing the granular impacts.

The purpose of this research is to design a comprehensive model to prevent price manipulation in the Iranian capital market. The approach used in this research is qualitative and has been used as the research method from the theory of grounded data (grounded theory). The data collection was done in depth and open interviews with 26 capital market elites and professors and students from different universities. For data analysis, the comparison method has been used during three stages of open, axial and selective coding. With regard to the analysis of data, we have found that the comprehensive model for preventing price manipulation consists of six main categories, including regulatory mechanisms, legal mechanisms, educational mechanisms, cultural mechanisms, structural mechanisms and implementation of the pattern of prevention. The price manipulation is explained in detail. Finally, the circumstances, the conditions of the intervention, the conditions governing (strategies), the strategies and the consequences have been identified.
