Abstract Wind induced wave is of great importance due to its high energy. In this study wave climate in the Gulf of Oman close to the Koohmobarak area is investigated. Wave climate study is necessary for determination of long-term analysis of wave statistics as well as climate change effects in the study area. First, wave climate is study using both measured and simulated wave data close to th...
Empirical Studies are indicative of four existing variables of tax rate, complexity of rules and regulations, social capital and inflation as the most influential factors in triggering tax evasion to be a mutual parameter among developing countries. in this paper, we regard all these factors in an econometric model to estimate the impact of each one in the context of the Iranian economy. To thi...
A commonly-used and naive solution to process data with missing attribute values is to ignore the instances which contain missing attribute values. This method may neglect important information within the data, significant amount of data could be easily discarded, and the discovered knowledge may not contain significant rules. Some methods, such as assigning the most common values or assigning ...
Empirical work in macroeconomics almost universally relies on the hypothesis of rational expectations. This paper departs from the literature by considering a variety of alternative expectations formation models. We study the econometric properties of a popular New Keynesian monetary DSGE model under different expectational assumptions: the benchmark case of rational expectations, rational expe...
