Evaluating the Move to a Linear Tax System in Germany and Other European Countries

This paper proposes a comparison of the results of tax policy analysis obtained on the basis of unitary and collective representations of the household. We first generate labour supplies consistent with the collective rationality, by use of a model calibrated on microdata as described in Vermeulen et al. [Collective Models of Household Labor Supply with Nonconvex Budget Sets and Nonparticipation: A Calibration Approach (2006)]. A unitary model is then estimated on these collective data and unitary and collective responses to a tax reform are compared. We focus on the introduction of linear taxation in Germany. The exercise is replicated for other European countries and other topical reforms. Distortions due to the use of a unitary model turn out to be important in predicting labour supply adjustments, in the design of tax revenue neutral reforms, and in predicting a reform’s welfare implications.

Social innovation indicators

This article provides the results of the Regional Social Innovation Index (RESINDEX), a conceptual and empirical model that explores indicators of social innovation at organizational and regional level. The RESINDEX model links absorptive capacity of knowledge and social innovation in four types of key regional agents: profit and non-profit organizations, universities, and technological centres. The pilot application of the RESINDEX model held in the Basque Country (Spain) during the year 2013. Within the framework of this study 282 regional organizations were surveyed. The article contributes to the conceptual and empirical discussion on indicators in social innovation.     

Introduction to the Special Issue on Domestic Violence and the South Asian Community

This article includes a discussion of elder sexuality, beginning with the problem of categorizing elders. This is followed by considerations of elder sexual practices, physiology, and social-psychological factors in elder sexuality. The article concludes with recommendations for people working with elders in regard to their sexuality.     

The benefits of information communication technology use by the homeless: a narrative synthesis review

Recent studies have suggested that technologies are becoming an increasingly ubiquitous element in the lives of individuals experiencing homelessness. With both Canadian and US researchers reporting staggering levels of homelessness on both sides of the border, an understanding and synthesis of the current literature exploring how technologies are being utilized by homeless individuals and how it may impact their well-being is of relevance to policy makers and social service organizations. The study explored and synthesized literature to examine the ways in which individuals experiencing homelessness utilize information and communication technologies (ICTs), and how the use of ICTs influences the health and social outcomes of individuals experiencing homelessness. The study examined 16 peer reviewed articles using a narrative synthesis systematic review, following three elements of the narrative synthesis approach: preliminary synthesis of findings; exploration of relationships between studies; and assessment of the robustness of the synthesis. In relation to what ICTs are used for by homeless individuals, three major themes emerged: social connectedness, identity management, and instrumental purposes. Furthermore, there was some tentative evidence about a positive relationship between ICT use among individuals experiencing homelessness and health outcomes. The paper discussed limitations, future areas of research, as well as some policy directions.     

Population and development redux

The effects of population growth on long-term economic development are obviously important. This paper introduces new predictions from a general Malthus-Boserup model of population growth and ideas-based technological change. It also tests these predictions using numerous data sources, empirical specifications, and sample periods. Time series tests reveal that the empirical associations that hold true in the modern era are completely reversed in pre-modern samples. Inferences drawn from the pre-modern population growth of geographically isolated populations are also reversed when relevant controls are taken into account. While there is a clear break with Malthusian theory, in general, and especially outside of the modern era, there is no unequivocal evidence supporting Boserupian views. An alternative model consistent with transitional demographic patterns is briefly discussed.     

Risk Perception Among Smokers: A Qualitative Study

The aim of this qualitative study is to identify the dimensions people used to assess the risk of smoking and then compare them with those used by health professionals in primary healthcare. Five discussion groups were conducted. The field work was carried out in Barcelona (Spain), from February 2005 to January 2006. Data were analyzed following a semantic‐thematic categorical content analysis (ACC‐ts). Results showed that people tend to employ stereotypical discourses when evaluating the risk of smoking. Similarly, they reassess the risk in the context of their life experience and incorporate new nuances to the arguments sustaining their behavior. Once this reassessment takes place, the decision to continue smoking emerges, and smokers come up with additional arguments justifying their habit (i.e., age, benefits related to costs). Professionals are aware of this process and its multidimensional nature. Nevertheless, their discourse loses this multidimensional feature when discussing the strategies they use at smoking cessation interventions. This qualitative study increases the understanding of various meanings that people attribute to their life experience. These assumptions may be useful for developing health practices that are closer to people. As a practical utility of these results, it would be interesting to apply a preliminary assessment of the different meanings that people attribute to smoking from their life context in risk communication.     

Experience with an electricity market simulation tool

A successful experience to train power producers on pool-based electricity markets presented. Trainees are arranged in groups and assigned, at random, a set of generators. They play the role of power producers and compete against each other with the target of maximizing their own profits. They have to bid in terms of price and quantity to try to sell energy to the consumers through the market. The trainer plays the role of the market operator. A market simulator and a computer communication network make it possible to simulate the actual functioning of a pool-based electricity market. The simulator is based on the widely used software package MATLAB, and a computer communication net, which can be replaced by the WWW.
