While the almost ideal demand system has received increasing attention in empirical studies of consumer demand, the fact that the underlying PIGLOG cost function is not globally regular has often led to violation of negative semidefiniteness in the estimated Slutsky matrix. This paper suggests a...

This paper utilizes the notion of `effective global regularity' and the intuition stemming from Cooper and McLaren (1996)'s General Exponential Form to develop a family of `composite' (product and ratio) direct, inverse and mixed demand systems. Apart from having larger regularity regions, the...
