    This article assesses the unilateral e ects on prices of a merger in the Portuguese mobile telephony market. We use aggregate quarterly data from 1999 to 2005 and a nested logit model to estimate the price elasticities of demand and the marginal costs of subscription of mobile telephony. Given these estimates, we simulate the e ects of the merger. We nd that the available mobile telephony subscription products are close substitutes. The merger may cause substantial price increases, even in the presence of large cost e ciencies. On average, prices increase by 7% without cost e ciencies, and by about 6% with a 10% marginal cost reduction

    Incentives in Surveys - Data Set

    Data set and codebook variables for paper Incentives in Surveys, accepted for publication in the Journal of Economic Psychology. Abstract: Surveys typically use hypothetical questions to measure subjective and unverifiable concepts like happiness and quality of life. We test whether this is problematic using a large survey experiment on health and subjective well-being. We use Prelec’s Bayesian truth serum to incentivize the experiment and defaults to introduce biases in responses. Without defaults, the data quality was good and incentives had no impact. With defaults, incentives reduced biases in the subjective well-being questions by inducing participants to spend more effort. Incentives had no impact on the health questions regardless of whether defaults were used

    In this paper, we describe our experience of using the Putting Women First protocol in the design and implementation of a cross-sectional study on violence against women (VAW) among 1607 immigrant women from Morocco, Ecuador and Romania living in Spain in 2011. The Putting Women First protocol is an ethical guideline for VAW research, which includes recommendations to ensure the safety of the women involved in studies on this subject. The response rate in this study was 59.3%. The prevalence of VAW cases last year was 11.7%, of which 15.6% corresponded to Ecuadorian women, 10.9% to Moroccan women and 8.6% to Romanian women. We consider that the most important goal for future research is the use of VAW scales validated in different languages, which would help to overcome the language barriers encountered in this study.En este trabajo se describe la experiencia de la aplicación del protocolo Putting Women First en el diseño y la realización de un estudio transversal sobre violencia contra las mujeres en 1607 mujeres inmigrantes procedentes de Marruecos, Ecuador y Rumanía residentes en España (2011). Este protocolo es un código ético para la investigación sobre la violencia contra las mujeres que incluye recomendaciones para preservar la seguridad de quienes participan en estudios sobre el tema. Se obtuvo una tasa de respuesta del 59,3%. La prevalencia de casos declarados de violencia contra las mujeres en el último año fue del 11,7%: el 15,6% en las mujeres ecuatorianas, el 10,9% en las marroquís y el 8,6% en las rumanas. El reto que consideramos más relevante para futuras investigaciones es la utilización de escalas sobre violencia contra las mujeres validadas para diferentes idiomas, con el objeto de romper las barreras lingüísticas encontradas en este caso.This study has been funded by the Carlos III Institute and The Spanish Ministry of Economy and Competitiveness for the2011–2012 period. It is also part of the Health and Immigration sub-programme of the CIBERESP
