Test for Aggregational Gaussianity (AG) in Petroleum Prices Returns

چکیده
The work aims at investigating and establishing if Aggregational Gaussianity, (AG) is in the dynamics of petroleum prices. This AG aspect phenomenon which empirical distribution log-returns tends to normality (or as time scale over returns are calculated increases). In order achieve this, price series was tested for arch effects. addition, tests were carried out using qualitative (graphical) approach inferential approach, (involving statistical inference). study shows that presence effects does not guarantee existence AG. It also observed may suggest hence, AG, on other hand, tests) gives a better picture actual conclusion, otherwise) data set, with 99.97% rejection from by three tests-Kolmogorov-simonorv,Shapiro-Wilks, Anderson-darling. circumstance, there no evidence confirm discernible non-existence instability prices, since one cannot invoke an invariant property among factors, make economy unstable it oil- driven. However, highest percentage budget country based sales, this reveals unstable, diversification proposed. softwares used Eviews 10, Minitab 18, Spss 17, Easy-fit 5.6 professional, R 3.2.2.

Increasing Returns, Imperfect Competition and Factor Prices
We show how, in general equilibrium models featuring increasing returns, imperfect competition and endogenous markups, changes in the scale of economic activity affect income distribution across factors. Whenever Þnal goods are gross-substitutes (grosscomplements), a scale expansion raises (lowers) the relative reward of the scarce factor or the factor used intensively in the sector characteriz...
متن کاملThe Distribution of Returns of Stock Prices
We perform a phenomenological study of stock price fluctuations of individual companies. We systematically analyze two different databases covering securities from the three major US stock markets. We consider (i) the trades and quotes (TAQ) database, for which we analyze 40 million records for 1000 US companies for the 2-year period 1994–95, and (ii) the Center for Research and Security Prices...
متن کاملA Simple Test for Non-Gaussianity in CMBR Measurements
We propose a set of statistics Sq for detecting non-gaussianity in CMBR anisotropy data sets. These statistics are both simple and, according to calculations over a space of linear combinations of three-point functions, nearly optimal at detecting certain types of non-gaussian features. We apply S3 to the UCSB SP91 experiment and find that the mean of the four frequency channels is by this crit...
