GOVERNANCE INSTITUTIONS AND PRIVATE INVESTMENT: AN APPLICATION TO THE MIDDLE EAST AND NORTH AFRICA

This paper addresses the issue of the low level of private investment in the Middle East and North Africa (MENA) region, with special emphasis on the role of governance. Based on the existing published reports, we categorize what types of governance institutions are more detrimental to entrepreneurial investments. We then estimate a simultaneous model of private investment and governance quality where economic policies concurrently explain both variables. Our empirical results show that governance plays a significant role in private investment decisions. This result is particularly true in the case of “administrative quality” in the form of control of corruption, bureaucratic quality, investment‐friendly profile of administration, law and order, as well as for “political stability.” Evidence in favor of “public accountability” is also found. Our estimations also stress that structural reforms like financial development, trade openness, and human development affect private‐investment decisions directly, and/or through their positive effect on governance.     

Critical resource: An institutional economics of the Internet addressing-routing space

This paper links the analysis of IP address policy to the established vocabulary and concepts of institutional economics. Internet addressing and routing are usually discussed in technical terms, yet embedded in this highly technical discourse are a number of critical economic concepts, such as scarcity, externalities, common pool resources, tragedy of the commons, and conflict over the distribution of costs. To solve these problems, governance institutions native to the Internet have evolved. Yet despite the centrality of addressing and routing to Internet governance, there is very little research literature that bridges economic, institutional and technical discussions of IP addressing and routing. This paper connects the techno-economic discussion to analysis of institutions and governance arrangements.     

IL-6在运动干预胰岛素抵抗中的作用综述

胰岛素抵抗（IR）发生于人体生理作用的任何方面,其抵抗机制十分复杂。有研究表明,运动能够改善IR,且在运动过程中骨骼肌所产生的白细胞介素-6（IL-6）可通过调节和控制各组织中的胰岛素作用及抵抗机制,通过不同的方式引起血糖指数、糖脂代谢、身体各组织器官血糖的改变,改善IR。因此,本文针对骨骼肌组织中的IL-6在胰岛素抵抗中的作用及其机制进行了简要综述。

Growth,Employment and Taxation with Distortions in the Goods and Labour Market

Abstract. This paper analyses taxation in the presence of distortions in goods and labour markets in an endogenous growth model. The government disposes of capital, labour and consumption taxes. It is shown that the market solution leads to suboptimally low levels of growth and employment. However, available tax instruments are sufficient to attain the first‐best growth path in this economy. The paper further explores the relative distortion of capital and labour taxes. For plausible parametrisations of the model, lowering capital taxes dominate reductions in labour taxes in welfare terms.
