in this paper, asymmetric effects of exchange rate fluctuation (according to positive and negative shocks) on real output were investigated. in the meantime, the study of behaviour of real output growth in iran’s economy over the period 1338-1386 was done. in specification of the output growth equation, in spite of considering positive and negative shocks of exchange rate, the effects of other ...
in very recent papers asmild et al. (2003) and halved et al. (2004) based upon potential improvement efficiency index (bogetoft and hougaard,1999) have suggested an alternative nonparametric frontier approach namely multi-directional inefficiency analysis (mea) to estimate the performance efficiency. mea has many advantages over data envelopment analysis (dea) as the standard nonparametric fron...
اخیراً اسمایلد (2003) و هالود و همکاران (2004)، بر مبنای شاخص کارایی بهبود بالقوه (بوجتوف وهاگارد 1999) روش جدید ناپارامتری مرزی تحلیل چند جهتی کارایی (mea) را برای محاسبه کارایی بنگاهها معرفی نمودند که مزایای زیادی نسبت به روش رایج تحلیل پوششی داده ها (dea) دارد. این روش به دلیل توانایی در محاسبه مجزای بهبود بالقوهی هر یک از نهادها یا ستانده ها، می تواند اندازه های قابل اتکاتری از عملکرد بنگا...
us 2008 financial crisis, spreaded out across the international stock markets in the second half of the year 2008. the crisis decreased the returns and increased the volatilities of almost all of the stock indices, however, its effects on iran’s stock markets were unexplored. financial limitations create an exclusive situation in iran’s stock market. using weekly data on the stock indices from ...
background and objectives: the escherichia coli strains are greatly important in nosocomial and community acquired infections. the aim of this study was to determine the transmission of bacterial infections using genetic analysis. materials and methods: two hundred and thirty escherichia coli strains, isolated from different clinical samples, were characterized by enterobacterial repetitive int...

در طول دو دهه اخیر مطالعات کاربردی بسیاری برای ارزیابی دلایل ناکارایی در صنایع مختلف از یک روش شبه پارامتری دو مرحلهای موسوم به مدل توبیت استفاده نمودهاند. کاربرد این روش برای نمونههای کوچک به دلیل امکان وجود تورش در نتایج آن، اخیراً مورد انتقاد بوده است. یک روش دو مرحلهای شبه پارامتریک بوتاسترپ شامل دو الگوریتم منفرد و مضاعف را برای حل این مشکل ارائه نمودهاند. این دو الگوریتم، تخمینهای ا...
The characteristics of crude oil and the factors affecting the price of this energy carrier have caused its price forecast to always be considered by researchers, oil market activists, governments and policy makers. Since the price of crude oil is affected by many factors, therefore, continuous studies should be done in this way so that the estimates made over time, the results are more accurat...
many empirical papers have applied a semi-parametric two-stage procedure named tobit model to investigate the sources of inefficiency in different industries over the last two decades. using this approach in small samples has recently been criticized for a possible bias in its results. in very recent papers simar and wilson (2007) have tackled this problem by suggesting an alternative bootstrap...
