Reconciling landowner income and land prices: the case of Spanish and California oak woodlands
Referencia: Instituto de Políticas y Bienes Públicos (IPP) CSIC, Working Paper 2015-02 Autores:

José L. Oviedo, Lynn Huntsinger & Pablo Campos

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-...

Measuring total social income of a stone pine afforestation in Huelva (Spain)

Paola Ovando, José L. Oviedo & Pablo Campos

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... Seguir leyendo

Human computing via online labor markets. The perils and promises of crowdsourcing in data-rich ecosystems
Referencia: Instituto de Políticas y Bienes Públicos (IPP) CSIC, Working Paper 2014-02 Autores:

Matthijs den Besten, Catalina Martínez, Nicolas Besson, Stéphane Maraut & Jean-Michel Dalle

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... Seguir leyendo

Comparing contingent valuation and choice modeling using field and eye-tracking lab data
Referencia: Instituto de Políticas y Bienes Públicos (IPP) CSIC, Working Paper 2014-01 Autores:

José L. Oviedo & Alejandro Caparrós

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... Seguir leyendo

Revealed preference land use models in Andalusia: integrating commercial and environmental variables
Referencia: Instituto de Políticas y Bienes Públicos (IPP) CSIC, Working Paper 2013-03 Autores:

José L. Oviedo & Alejandro Caparrós

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... Seguir leyendo

Identifying author-inventors from Spain: methods and a first insight into results
Referencia: Instituto de Políticas y Bienes Públicos (IPP) CSIC, Working Paper 2013-02 Autores:

Stéphane Maraut & Catalina Martínez

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... Seguir leyendo

Citizens’ support for government spending on Science and Technology
Referencia: Instituto de Políticas y Bienes Públicos (IPP) CSIC, Working Paper 2013-01 Autores:

Luis Sanz-Menéndez, Gregg Van Ryzin & Eloísa Del Pino

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... Seguir leyendo

Assessing the income value of private amenities in California oak woodlands
Referencia: Instituto de Políticas y Bienes Públicos (IPP) CSIC, Working Paper. 2011-10 Autores:

Jose L. Oviedo, Lynn Huntsinger, Pablo Campos & Alejandro Caparrós

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... Seguir leyendo

Isomorphism, demand and ideology in public policy. Forums for immigrant integration in 15 Regions of Spain

David H. Corrochano

This paper defining the causes which underlie a public policy: Forum for immigrant participation. Little is known about the specific motivations which lead different governments’ decisions to institute such policies. This process cannot only refer to the theoretical objectives, but must consider the context in which certain Governments are brought to implement such policies while others do not... Seguir leyendo

Historic Forage Productivity and Cost of Capital for Cow-Calf Ranches in California
Referencia: Instituto de Políticas y Bienes Públicos (IPP) CSIC, Working Paper. 2011-08 Autores:

Philip Brownsey, Jose L. Oviedo, Lynn Huntsinger & Barbara Allen-Diaz

Much has been made of the low returns on investment for western rangeland ranching. However, little work has been done to empirically compare these returns to the return that would be demanded by financial markets from assets with similar risk and return characteristics. This study uses historical forage productivity data from three locations in California’s Mediterranean rangelands to... Seguir leyendo
