Despite considerable interest in the dynamics of populations subject to temporally varying environments, alternate population growth rates and their sensitivities remain incompletely understood. For a Markovian environment, we compare and contrast the meanings of the stochastic growth rate (lambdaS), the growth rate of average population (lambdaM), the growth rate for average transition rates (...

This paper studies whether information, communication or automation technologies can enable the consumer demand response necessary to expand dynamic pricing in resource markets such as electricity. Treatment effects from household random assignment to technologies and different price distributions reveal substantial demand reductions during critical and peak times for all technologies, with aut...

This study evaluates the household food demand patterns among different income sorts in urban and rural areas of Pakistan and estimation of food expenditure and household size elasticities. The different income sorts are the Lower Income Group(≤ 8000), Lower-middle Income Group(800112000), Middle Income Group(12001-18000),Upper-middle Income Group (18001-35000) and Upper Income Group (35000+) P...

The estimation of price elasticities of alcohol demand is valuable for the appraisal of price-based policy interventions such as minimum unit pricing and taxation. This study applies a pseudo-panel approach to the cross-sectional Living Cost and Food Survey 2001/2-2009 to estimate the own- and cross-price elasticities of off- and on-trade beer, cider, wine, spirits and ready-to-drinks in the UK...

Available online 8 October 2011 We empirically examine the impact of trade on labor demand elasticities using Korean firmlevel data. In our analysis, in addition to looking at the impact of liberalizing import restrictions, we take into account the fact that greater trade integration also leads to better and greater export possibilities. While we find that Korea's own tariffs do not have any st...

We explore how and by how much assumptions about elasticities of substitution affect estimates of the cost of GHG emissions reduction policies in computable general equilibrium (CGE) models using G-Cubed, an intertemporal CGE model, to carry out a sensitivity and factor decomposition analysis. The results suggest that the average abatement cost rises non-linearly as elasticities are reduced. Su...

This paper examines how estimates of the price elasticity of demand for beer vary with the choice of alcohol price series examined. Our most important finding is that the commonly used ACCRA price data are unlikely to reliably indicate alcohol demand elasticities-estimates obtained from this source vary drastically and unpredictably. As an alternative, researchers often use beer taxes to proxy ...

Recent work has provided compelling evidence of a long-term decline in US female labor supply elasticities with respect to wages and to income. While previous work used crosssectional data from the Current Population Survey (CPS), we reexamine the trend for married women using panel data from the Panel Study of Income Dynamics (PSID) from 1980 to 2006. We find evidence in support of a long-term...

This paper investigates the effect of price variations on the diet composition in Britain. It describes the dynamics of food demand in relation to food prices over time using data from the British National Food Survey (NFS) covering the period 1975-2000. Demand elasticities with respect to price elasticities are estimated by solving a quadratic almost ideal demand system (QUAIDS) model controll...
