abstract in this paper we test two versions of convergence hypothesis namely deterministic or conditional convergence and stochastic or catching up hypothesis using carrion-i-silvestre et al. (2005) stationary test. the results show latin and south american countries (lsa) catching up process toward the usa failed in 1980s and somewhat in 1990s. but in 2000s most of them could lie in convergenc...

This paper develops a simple accounting framework that measures the effect of resource misallocation on aggregate productivity. This framework is based on a multi-sector general equilibrium model with sector-specific frictions in the form of taxes on sectoral factor inputs. This framework is flexible for demand side assumptions such as preference and aggregate production function. Moreover, thi...

The Middle East and North Africa (MENA) region suffers a drastic change from a traditional diet to an industrialized diet. This has led to an unparalleled increase in the prevalence of chronic diseases. This review discusses the role of nutritional genomics, or the dietary signature, in these dietary and disease changes in the MENA. The diet-genetics-disease relation is discussed in detail. Sel...

This paper o"ers an explanation for the coexistence of convergence across countries and the lack thereof at the regional level in the European Union. The model shows that, even if it accelerates growth and brings convergence across countries, the intensi5cation of international knowledge spillovers due to more cross-country interaction may exacerbate within-country regional disparities, if regi...

This study explores the importance of tacit knowledge transfer for international technology di¤usion by examining ethnic scienti…c communities in the US and their ties to their home countries. US ethnic research communities are quanti…ed by applying an ethnic-name database to individual patent records. International patent citations con…rm knowledge di¤uses through ethnic networks, and manufact...

Recent diffusion models cannot explain why the success of technology diffusion depends so critically on developing countries’ human capital levels. This paper examines three main issues. First, we endogenize both appropriate technologies and human capital formation. Second, we refine the human capital accumulation process by introducing uncertainty about worker quality and training efficiency. ...

abstract i n this paper, we investigate the existence and the nature of real exchange rate misalignment in organization of the petroleum exporting countries (opec). to do this we estimated a cross country basic real exchange rate determination model for 1990-2012 and extracted historic trend of misalignment. the results imply that all opec countries have had misalignment -of different kinds tho...

Empirical work on cross-country growth has focussed almost exclusively on the speed of convergence to steady state and the variations in steady state levels. This paper examines the estimated long-run growth rate, i.e. the rate of steady state growth, in a Solow growth model. All estimates of common world steady state growth are shown to be zero or significantly negative under the null model. T...

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...

Globalization is accompanied by increasing current account imbalances. They can undermine the positive impacts of increasing international cooperation and trade on economic growth. By applying an economic growth model that requests for long-term compensation of short-term current account deficits, we derive patterns of international trade. Model output, however, is challenged by empirical data ...
