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...

The purpose of this paper is to present the possibility of replacing physical unit cost in transportation or distribution problems by an aggregate coefficient, getting qualitative and subjective considerations involved. The model for constructing aggregate cost is a two stage multiple attribute decision-making problems. In the first stage supply points, demand points and routes of transportatio...

This paper employs a multivariate dynamic conditional correlation GARCH model, which is developed by Engle (2001, 2002), to detect the timing and nature of changes in the comovement between Iranian output and prices for the periods after Iran–Iraq war , known as imposed war . The results showed that there is a weak correlation between output and prices after imposed war and  varies periodically...

This paper highlights a previously unnoticed property of commonly-used discrete choice models, which is that they feature parallel demand curves. Specifically, we show in additive random utility inverse aggregate curves shift with respect to variety if and only the shocks follow Gumbel (Type 1 Extreme Value) distribution. Using results from Value Theory, provide conditions for other distributio...
