This study estimates the aggregate import demand function for Nigeria for the period of 1980 2010. Cointegration approach was implemented. While the error correction term in the estimated VEC model was evaluated for long run causal relationship, the short term coefficients were gauged for short term causal relationship between the explained and the explanatory variables. Results indicate: (i) t...

This paper investigates the behaviour of Indian aggregate imports during the period 1971-1995. In our empirical analysis of the aggregate import demand function for India, cointegration and error correction modelling approaches have been used. In the aggregate import demand function for India, import volume is found to be cointegrated with relative import price and real GDP. Our econometric est...

In this paper we summarize some of our results on aggregation of individual fuzzy preferences. We focus on aggregation functions that preserve some types of transitivity, by giving complete characterization and representation of two main aggregation classes. These are closely related to the weighted maximum and minimum operations. We also establish full characterization of these weighted forms ...

Traditionally, policymakers and financial markets have regarded the “core” consumer price index (CPI) as a key inflation indicator. The core CPI, a special index published by the Bureau of Labor Statistics (BLS), excludes the volatile prices of food and energy. In excluding these components, BLS recognizes that prices that swing dramatically in response to unusual shifts in weather and other un...

In this study, yield-water and profit function was used to obtain water demand function in agriculture sector. The results showed that the ratio of actual to potential Evapotranspiration had positive, significant effecton the ratio of actual to potential yield for wheat and barley. Also, square ratio of actual to potential Evapotranspiration had negative, significant relationship. After estimat...

The main purpose of this study is to ascertain the determinants demand for money and its stability in Azerbaijan using monthly time series data spanning from January 2006 November 2020. Johansen cointegration, vector error correction model (VECM) Impulse Response Function were employed investigate relationship between real (M1), macroeconomic variables, namely income, inflation, interest rate e...

presently, the culture of economics in somecountries is given top priority against other sectors of civilian economics. this importantis not only due to the economical values of culture but also due to the outmost importanteffects which are able to boost the civilian economics both direct and indirect. in iranalso, the culture economics has its own specific importance and it includes industries...

iran is one of the most energy-rich countries subsidizing energy carriers, especially in the agricultural sector, to the extent that the resulting growth is at the expense of the environment. this study tries to investigate the potential impacts of energy price reform on the agro-environment, based on the marginal abatement costs (macs) of emissions. firstly, the energy demand function of the a...
