The aim of this paper is to analyze the relationships between common shocks affecting the real economy and those underlying co-fluctuations in U.S. financial markets. In order to do this, we test for links between these common factors and also use the econometric theory of non-stationary panel data to estimate the relationships. The estimates prove the existence of significant relationships bet...
there are two major theories of measurement in psychometrics: classical test theory (ctt) and item-response theory (irt). despite its widespread and long use, ctt has a number of shortcomings, which make it problematic to be used for practical and theoretical purposes. irt tries to solve these shortcomings, and provide better and more dependable answers. one of the applications of irt is the as...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
چکیده روش های متعددی برای برآورد رواناب حاصل از بارش در حوضه های آبریز وجود دارد. یکی از این روش ها استفاده از مدل های هیدرولوژیکی است. با استفاده از مدل های هیدرولوژیکی و شبیه سازی فرآیندهای هیدرولوژیکی می توان با صرف کمترین زمان و هزینه، رواناب و مولفه های دیگر چرخ? هیدرولوژیکی را برآورد کرد. از آنجا که در حوضه های آبریز اندازه گیری تمام کمیت های مورد نیاز برای تحلیل رواناب ممکن نیست، انتخاب...
While the gravity model has been one of the most successful applications in empirical trade, various attempts are still made to improve its regression results. One of the recent developments in the econometric technique is to extend the gravity model to a panel data framework and take into consideration the existence of dynamic effects. In this paper, we apply these new techniques to examine th...
methodology non-native participants in this study were sixty ba students majoring in english literature and teaching english as a foreign language at khayyam university of mashhad. they were senior students, between 21 to 24 years old, who had studied english for at least three and a half years and had passed several courses including grammar, reading, conversation, and writing. this was assum...
This paper reports on an experiment designed to analyze information revelation in sequential guessing games. We observe a remarkable frequency of equilibrium outcomes. Deviations from the equilibrium are explained by learning considerations. By means of applying panel data econometric techniques, we find the presence of error cascades, which represent the situation where the deviation from lear...
Using newly developed econometric techniques, Pedroni and Yao (2006) show that China has been experiencing regional income divergence since the Reform Period, and that traditional explanations explaining divergence are insufficient. This paper considers the role of labor mobility in the context of endogenous growth with positive externalities to human capital. Using provincial level data on inc...
due to increasing number of international tourists and the enhancing role of tourism in economies of countries and competing environment, recognizing determinants in attracting international tourists seems very essential than ever before. public and private sectors need to examine determinants and forecast tourism demand. the primary aim of this study is using econometric techniques to analyzin...
in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...
