Performance of error component models for status-quo effects in choice experiments.
No full textEnvironmental economists have advocated the use of choice modelling in environmental valuation. Standard approaches employ choice sets including one alternative depicting the status-quo, yet the effects of explicitly accounting for systematic differences in preferences for non status-quo alternatives in the econometric models are not well understood. We explore three different ways of addressing such systematic differences using data from two choice modelling studies designed to value the provision of environmental goods. Preferences for change versus status-quo are explored with standard conditional logit with alternative-specific constant for status-quo, nested logit and a less usual mixed logit error component specification (kernel logit). Our empirical results are consistent with the hypothesis that alternatives offering changes from status-quo do not share the same preference structure as status-quo alternatives, as found by others in the marketing literature, in the environmental economic literature and in food preference studies. To further explore the empirical consequences of such mis-specification we report on a series of Monte Carlo experiments. Evidence from the experiments indicates that the expected bias in estimates ignoring the status-quo effect is substantial, and—more interestingly—that error component specifications with status-quo alternative specific-constant are efficient even when biased. These findings have significant implications for practitioners and their stance towards the strategies for the econometric analysis of choice modelling data for the purpose of valuation
Willingness-to-pay for renewable energy: Primary and discretionary choice of British households’ for micro-generation technologies
No full textThis paper documents the policy context of renewable energy production in the European Union. The research adopts a choice experiment approach to investigate households' WTP for these renewable energy technologies in the UK. The micro-generation technologies comprise solar photovoltaic, micro-wind, solar thermal, heat pumps, and biomass boilers and pellet stoves. The study compares the results from conditional and mixed logit models, which estimate the distribution of utility coefficients and then derives WTP values as a ratio of the attribute coefficient to the price coefficient, with a model in which the WTP distribution is estimated directly from utility in the money space. The results suggest that whilst renewable energy adoption is significantly valued by households, this value is not sufficiently large, for the vast majority of households, to cover the higher capital costs of micro-generation energy technologies

Effective Willis constitutive equations for periodically stratified anisotropic elastic media
No full textA method to derive homogeneous effective constitutive equations for periodically layered elastic media is proposed. The crucial and novel idea underlying the procedure is that the coefficients of the dynamic effective medium can be associated with the matrix logarithm of the propagator over a unit period. The effective homogeneous equations are shown to have the structure of a Willis material, characterized by anisotropic inertia and coupling between momentum and strain, in addition to effective elastic constants. Expressions are presented for the Willis material parameters which are formally valid at any frequency and horizontal wavenumber as long as the matrix logarithm is well defined. The general theory is exemplified for scalar SH motion. Low frequency, long wavelength expansions of the effective material parameters are also developed using a Magnus series and explicit estimates for the rate of convergence are derived.Peer reviewedReceived July 22, 2010; accepted December 15, 2010; published online April 21, 2011.
