We perform two convergent validity tests in a choice experiment applied to public recreation in Stone pine and Cork oak forests in Spain. We compare choice and ranking recoded as a choice in an experiment with three alternatives plus status quo. Our results show convergent validity for both structural models and willingness to pay estimates. The same experiment includes two payment-vehicles, an entrance-fee to access the forest and an increase in trip-expenditures due to an increase in gas prices, simultaneously in the choice sets. We obtain significant differences in willingness to pay...

The deep economic crisis and the sharp rise in electricity prices have had a strong effect on electricity demand by Spanish households. This paper aims to analyse the responsiveness of household electricity demand and the welfare effects related to both factors in the 2006-2012 period. The results show that the electricity consumption of medium-high income households is particularly responsive to price increases, whereas that of medium-low income households is more responsive to changes in income. The retail electricity price increases and the economic crisis have led to generally lower...

We integrate data from commercial operations, non-market private amenities and capital gains to measure landowner income and profitability in six oak woodland case studies from Spain and California. Results show that private amenities make the greatest contribution to landowner income, while commercial benefits alone fall short of explaining land prices. We also estimate landowner self-employed labor income, but its contribution is marginal. Total real profitability ranges from 3.2 to 7.8% in the Spanish cases and from 6.0 to 9.3% in the California cases, showing that these oak woodlands...

We estimate the total social income delivered by a simulated Stone pine ( Pinus pinea L.) afforestation investment in Huelva province, Spain. We consider the following private and public products: timber, pinecones, forestry conservation services, landowner amenities, landscape conservation, public recreation and carbon sequestration services. We show how total income of each single product is distributed into the partial rewards to labor and to environmental and manufactured assets. Results demonstrate that private income accounts on average for 46% of the total social income over the...

In this article, we focus on the need for “human computing” in data-rich ecosystems, notably as a consequence of data variety and typically for name disambiguation, and explore ways to manage it via online platforms for paid crowdsourcing. Based on several studies of Amazon Mechanical Turk, a well-established platform for matching data treatment tasks to human beings willing to carry them out, we illustrate the difficulties involved as requesters compete for the attention of workers. We suggest that researchers should shift from a technical analysis and tentative resolution of human...

We compare contingent valuation and choice modeling with field and eye-tracker data. Contrary to previous research, results yield significantly different structural models. These divergences remain for modified formats that minimize visual and cognitive differences between formats. We also find divergent results concerning information processing. In choice modeling, respondents devote more time to attributes, including the bid, although total answering time does not vary. Presenting several questions with varying attribute levels works for choice modeling but not for contingent valuation....

We investigate transitions among crop, grass and forest land uses in Andalusia (Spain) through an econometric model that uses individual land use decisions observed in the Corine Land Cover database as dependent variable, and net income, subsidies and biophysical and environmental factors as explanatory variables. Using multinomial logit models (fixed and random parameters), we identify both monetary and environmental and biophysical variables as significant in explaining land use decisions, but model performance significantly improves with the latter variables. We also identify the role...

The aim of this paper is to describe a matching and disambiguation methodology for the identification of author-inventors located in the same country. It aims to maximize precision and recall rates by taking into account national name writing customs in the name matching stage and by including a recursive validation step in the person disambiguation stage. An application to the identification of Spanish author-inventors is described in detail, where all SCOPUS 2003-2008 publications of Spanish authors are matched to all 1978-2009 EPO applications with Spanish inventors. Using this data, we...

This paper analyses public support for government spending on science and technology (S&T) and its determinants. It constructs hypotheses based on previous findings from two streams of research: public preferences for government spending and public understanding of science. Using data from a large national survey in Spain, it develops multivariate models to test the relevance of various predictors of public support for government spending on S&T. Findings identify several variables that are clear and consistent predictors of public support for government spending on science and...

A contingent valuation technique was applied to a 2004 sample of oak woodland landowners in California to assess its usefulness in estimating the non-market income and land price value of oak woodland properties. Non-market benefits have long been considered an important influence on rangeland landowners, but beyond comparing market production and land price, few studies have attempted to place a monetary value on them. Landowners were asked to estimate the maximum amount of earnings that they were willing to forgo before selling their property to invest in more commercially profitable non...
