Generalized Selection Bias and The Decomposition of Wage Differentials The major contribution of this paper is ending a new and flexible way to measure the effects of selection on log-wages. In this context, we offer a general approach to performing decomposition analysis when selection effects are present. We call the difference between unconditional and conditional expectations of the log-wag...

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...

Recent evaluations of the impact of Turkish healthcare reforms on the efficiency of public hospitals suffer from simultaneous structural changes in the healthcare sector as well as from lack of data on some of the key ingredients of the reform. In this note, we analyze the major obstacles in a fair evaluation of the efficiency of public hospitals taking Sulku(2011)’s data envelopment analysis a...

abstract o ur basic aim in this paper concerns the question that if overusing the information technology by service and manufacturing firms can increase the total productivity resulting from this kind of technology regarding the iran's economic structure and conditions. for this purpose, we primarily evaluate the productivity resulting from the rate of firms' use of it for the differe...

Proteins usually consist of several structural domains which play an important role in the classification and analysis of them. As the number of known protein structures grows at an exponential rate, a computer-aided domain decomposition of proteins becomes desirable. We present three different decomposition methods in this report. They are based on a graph representation of the proteins. These...

the present study surveys the effect of bank-specific, industry-specific and macroeconomic conditions on bank performance to examine the structure-conduct-performance (scp) hypothesis in iranian banking industry. to achieve this goal, we drew upon the panel data technique to analyze the data of eleven public and private iranian banks during 2001-2006. firstly, productivity was calculated by usi...

Abstract In this paper,using a structural decomposition analysis (SDA) and the latest available input-output tables we investigate the sources of labor productivity growth in Norway, South Korea and Iran. Then, the contribution of each source in the growth of labor productivity is discussed. The results show that among six factors, value added coefficient is the most influencing factoracross al...

This paper quantifies the contributions of sectoral productivity growth and structural change to aggregate productivity convergence. Existing evidence is inconclusive because it focuses on convergence within sector and its methodology depends sensitively on the conversion factor used to compare sectoral productivity levels across countries. Thus, a methodology – β-decomposition – is proposed to...

This paper applies an established bid-ask spread decomposition model to short-term interest rate (STIR) futures to assess the impact of both the migration from floor to electronic trading and European Monetary Union (EMU). Additionally, the paper presents and tests a modified decomposition model which is specifically adapted to the features of order-driven markets. The latter model provides muc...

In this paper, we propose a model based on multivariate decomposition of multiplicative— absolute values and signs—components of several returns. In the m-variate case, the marginals for the m absolute values and the binary marginals for the m directions are linked through a 2m-dimensional copula. The approach is detailed in the case of a bivariate decomposition. We outline the construction of ...
