Stochastic volatility demand systems [PDF]

Econometric Reviews, 2015
We address the estimation of stochastic volatility demand systems. In particular, we relax the homoscedasticity assumption and instead assume that the covariance matrix of the errors of demand systems is time-varying. Since most economic and financial time series are nonlinear, we achieve superior modeling using parametric nonlinear demand systems in ...

Embedding in Market Demand Systems

Journal of Environmental Economics and Management, 1996
This paper addresses the question whether the contingent valuation (CV) is unreliable because of the embedding phenomenon, namely that willingness to pay for a particular commodity may vary greatly depending on whether the good is assessed on its own or is embedded a part of a more inclusive.

Fractional demand systems

Journal of Econometrics, 1987
Abstract This paper provides a complete characterization of Fractional Demand Systems, which are utility-derived demand equations having quantities or budget shares proportional to af + bg, where f and g depend on income and a and b vary across goods and depend on prices.

Conditional Correlation Demand Systems

Computational Economics, 2018
We address the estimation of singular demand systems with heteroscedastic disturbances. As in Serletis and Isakin (Econ Rev 36:1111–1122, 2017) and Serletis and Xu (Empir Econ, 2019, forthcoming) we assume that the covariance matrix of the errors of the demand system is time-varying, and contribute to the literature by considering the constant ...

Differential consumer demand systems

European Economic Review, 1985
It is shown in this paper that several well-known systems like the Rotterdam model and the Almost Ideal Demand System can be seen as different parametrizations of the budget share differential equation. Using a third parametrization a new system, called the CBS system, is developed and discussed. Special attention is given to the relative price version
