بهرهوری سبز، بهعنوان مهمترین هدف برای افزایش بهرهوری در کنار حفاظت از محیطزیست که پایهو اساس توسعه پایدار است، حائز اهمیت میباشد. هدف اصلی این پژوهش بررسی عوامل مؤثر بر رشد بهرهوری سبز در اقتصاد ایران میباشد، لذا در این مطالعه از شاخص مالمکوئیست و مالمکوئیست-لیونبرگر بهترتیب برای اندازهگیری بهرهوری و بهرهوری سبز استفاده شده است. همچنین عوامل مؤثر بر رشد بهرهوری سبز در اقتصا...
<p>The aim of this paper is to study the concepts foreign direct investment (FDI) and economic growth as well relationship between them through a literature review papers published from 1990 until today. In order for better results be achieved, divided into three phases, each reviewing different decade. particular, first phase reviews period 2000, second 2001 2012, while third 2013 up dat...
We estimate total factor productivities at the sector level for 72 countries and 5 decades, and examine how they evolve over time in both developed and developing countries. In both country groups, there has been relative productivity convergence: productivity grew systematically faster in sectors that were initially relatively less productive. These changes have had a significant impact on tra...
In this paper we present an algorithm that deals with trade interactions within a multi-region model. In contrast to traditional approaches this algorithm is able to handle spillover externalities. We focus on technological spillovers which are due to capital trade. The algorithm of finding a paretooptimal solution in an intertemporal framework is embedded in a decomposed optimization process. ...
In an open economy, can unilateral environmental policies undertaken by a group of committed countries ensure sustainable growth? This paper addresses this question in a dynamic model with directed technical change. There are two countries and two tradeable goods. One of the two goods (the polluting good) is produced with a clean input and a dirty input, which causes a global externality. Innov...
We suggest a possible explanation for cross-country differences in total factor productivity. Many technologies used by LDCs are developed in OECD economies, and as such, are designed to make optimal use of the skills of these richer countries' workforces. Due to differences in the supply of skills, some of the tasks performed by skilled workers in richer economies will be carried out by unskil...
In a healthy economy, plant turnover increases aggregate productivity because efficient producers are more likely to survive. Given high entry and exit rates and the potential importance of turnover in accounting for aggregate productivity, in this paper we examine the determinants of plant exits and then examine how exits and other forms of output reallocation contribute to aggregate productiv...
By generalizing Hamilton’s model of the US business cycle to a three-regime Markov-switching vector autoregressive model, this paper analyzes regime shifts in the stochastic process of economic growth in the US, Japan and Europe over the last four decades. Empirical evidence is established for the presence of a structural break in the expansionary GDP growth for the US and Japan based on an out...
â â â â â â â â abstract: â there is a significant relationship between economic growth and the degree of urban concentration, as measured by primacy or the share of the largest city in an urban system. in accordance to urban economic theories, there is an inverse-u shape relationship between urban concentration âurban primacy- and economic growth. that is, as economy grows, urban concen...
Abstract. Water-soluble and water-insoluble organic aerosol (WSOA WIOA) constitute a large fraction of fine particles in winter northern China, yet our understanding their sources processes are still limited. Here we have comprehensive characterization WSOA cold season Beijing. Particularly, present the first mass spectral WIOA by integrating online offline measurements from high-resolution spe...
