THE EXTENDED ECONOMETRIC INPUT-OUTPUT MODEL WITH HETEROGENEOUS HOUSEHOLD DEMAND SYSTEM

This paper proposes an extension to the regional econometric input–output model (REIM) [Conway, R.S. (1990) The Washington Projection and Simulation Model: A Regional Interindustry Econometric Model. International Regional Science Review, 13, 141–165; Israilevich, P.R., G.J.D. Hewings, M. Sonis and G.R. Schindler (1997) Forecasting Structural Change with a Regional Econometric Input–Output Model. Journal of Regional Science, 37, 565–590]. We integrate a demand system with age and income parameters into the REIM. The extended model thus addresses concerns about the effects of household heterogeneity. The initial testing is conducted with a model for the Chicago metropolitan area. First, using aggregate expenditure data by income and age groups, the almost ideal demand system with group fixed effects is constructed. Next, the estimated demand system is linked to the REIM to reflect long-term changes in the age and income distribution of households. The long-range simulation from the extended model takes into account structural changes in expenditure type stemming from changing demographic composition. The extended model further broadens the scope of impact analysis under various scenarios associated with age and income changes.

Control of cavity cross section in microplasma devices: Luminance and temporal response of 200×100 and 320×160 arrays with parabolic Al2O3 microcavities

Intense green luminance and luminous efficacies approaching 4 lm/W have been observed for large (50×50 to 320×160) arrays of microplasma devices with parabolic cross-sectional Al2O3 microcavities and conformal aluminum electrodes, operating in Ne/Xe gas mixtures. Precise control of the cross-sectional geometry and surface morphology of the cavities within Al/Al2O3 microplasma devices having a dielectric barrier structure has been achieved with a sequence of wet electrochemical processes. Continuous variation of the cavity cross section between a linear taper and parabolic geometry can be specified and all dimensions controlled to within ±2%. Aluminum electrodes encompassing each cavity are azimuthally symmetric and the inner face of each electrode is conformal to the Al2O3 microcavity wall. Arrays comprising 20 000 devices (in a 200×100 configuration) with a parabolic microcavity wall profile and an emitting aperture 160±2 μm in diameter produce a green luminance >1800 cd/m2 and a peak luminous efficacy o...

Addressable, large scale arrays of microcavity plasma devices have been fabricated by wet chemical processes. Dielectric encapsulated aluminum microcavity electrodes having cavities with a diameter of 100–200 μm are formed by wet electrochemical process suitable for low cost manufacturing. This presentation reports device structure and cell designs for high pressure Xe microplasmas.

Bayesian estimation of labor demand by age: theoretical consistency and an application to an input–output model

ABSTRACT Extended input–output models require careful estimation of disaggregated consumption by households and comparable sources of labor income by sector. The latter components most often have to be estimated. The primary focus of this paper is to produce labor demand disaggregated by workers’ age. The results are evaluated through considerations of its consistency with a static labor demand model restricted with theoretical requirements. A Bayesian approach is used for more straightforward imposition of regularity conditions. The Bayesian model confirms elastic labor demand for youth workers, which is consistent with what past studies find. Additionally, to explore the effects of changes in age structure on a regional economy, the estimated age-group-specific labor demand model is integrated into a regional input–output model. The integrated model suggests that ceteris paribus ageing population contributes to lowering aggregate economic multipliers due to the rapidly growing number of elderly workers who earn less than younger workers.

Linear Arrays of Microchannel Plasmas in Monolithic

Linear microplasmas have been produced within rectangular channels, 75 × 75 μm2 in cross section and 7 cm in length. Arrays of such channels have been fabricated in single sheets of 127-μm-thick aluminum foil by a photolithographic step and an electrochemical process. Arrays comprising 20 parallel channels have been operated in the rare gases, N2, and air at pressures in the 100-760-Torr interval.

Regional modelers have spent a great deal of time and energy worrying about the level of sectoral aggregation but relatively little time considering the implications of aggregation of households into a representative household. In the US, households account for 70% of GDP on the expenditure side and increasing concerns about rising income inequality suggest that greater household disaggregation might be warranted. This paper provides a sampling of some evidence of the impacts for such disaggregation in regional econometric-input-output and computable general equilibrium models; attention is directed to disaggregation by age and income and a variety of experiments reveal the implications on a regional economy over the short- and long-run. Given the increasing attention on income distribution and inequality, the opportunity exists to provide important contributions to this literature by exploring the mechanisms of income formation, especially from non-wage and salary sources.
