Changes in Climate parameters have been accelerated in the coming age, which can affect agricultural activities directly and indirectly. Temperature and precipitation are the most complex climatic factors. Spectral analysis is a scientific and efficient technique used to recognize and detect the hidden behaviors of these variables. In this research, in order to study and analyze the temperature...
The Rebound effect refers to the reactions that occur to the advancement of technology and the increase of energy efficiency, and these reactions prevent the achievement of the desired goal completely. In this study, in order to investigate the effect of energy return on the value added of Iranchr(chr(chr('39')39chr('39'))39chr(chr('39')39chr('39')))s industrial sector, first by estimating the ...
The basis for this paper is the pricing of multi-period rate of return guarantees. These guarantees can typically be found in life insurance and pension contracts. We derive closed form solutions, expressed by the cumulative multivariate normal probability distribution, for multiperiod rate of return guarantees on both a money market account and a stock. The guarantees of Hipp (1996), Persson a...
The importance of information in the field of stock returns predictions has promoted many researchers to follow and find the variables and the indexes which have significant relationship with stock returns. This information can be divided into two separate categories of financial and non-financial information. The final results obtained from several researches in this area confirm that both fin...
A general discrete-time stochastic control model is developed which encompasses many wellknown economic models. In the context of the general model, sufficient conditions are derived for the equivalence and approximate equivalence of myopic (sequential single-period) and global (simultaneous multi-period) expected return maximization. A bound provided for the global return loss resulting from m...
Regional Flood Frequency Analysis (RFFA) is an efficient method in flood discharge estimation in ungauged watersheds or with short-term statistics. The purpose of the present study is to evaluate the hybrid method in RFFA and maximum flood discharge estimation in the Namak Lake watershed, Iran. For this purpose, 16 hydrometric stations were selected. The selected hydrometric stations were then ...
