Bayesian Estimation of Regional Production for CGE Modeling

Abstract Computable general equilibrium (CGE) models are often criticized for using restrictive functional forms and relying on external sources for parameter values in their calibration. CGE modelers argue that in many instances reliable econometric estimates of important model parameters are unavailable because they must be estimated using small numbers of time‐series observations. To address these criticisms, this paper uses a Bayesian approach to estimate the parameters of a translog production function in a regional computable general equilibrium model. Using priors from more reliable national estimates, and parameter restrictions required by neoclassical production theory, estimation is done by Markov chain Monte Carlo simulation. A stylized regional CGE model is then used to contrast policy responses of a Cobb‐Douglas specification with those from the estimated translog equation.     

Bounded at the driveway’s edge: body-space tensions encountered by children with mobility impairments in moving about the neighbourhood street

ABSTRACT

Research has shown the neighbourhood as an influential environment concerning children’s independent mobility and activity participation. However, its influence on the everyday experiences of children with disabilities is not well understood. This article addresses this gap by studying the accounts of ten nine-12 year olds from south-east Queensland, Australia, who have diverse mobility impairments. This phenomenological study reveals mobility is a conditional act. Conditionality is understood by the way social and spatial factors intersect to influence one’s mobility about the street – or in our case coerced immobility. The body-space practices also reveal a mismatch between children’s embodiment and the neighbourhood environment, which intensified and converged at the absent footpath, with crucial repercussions for their spatial agency and activity participation. The findings suggest the importance of understanding diverse body-space practices in mobility studies and the need to contest ableism in street design to create inclusive walkable neighbourhoods for all.
