Hirschman meets Williamson: Relationship-specific investment and loyalty

In Albert Hirschman’s theory, loyalty plays a key role in the equilibrium between exit and voice. This article extends economic (rational choice) analysis to the emergence of loyalty, which Hirschman considers an exogenous factor. This is accomplished by linking Williamson’s theory of specific investment to Hirschman’s model. Three cases are distinguished: (1) loyalty is due to specific investment; (2) loyalty is due to (intermediate) factors influenced by specific investment; and, (3) loyalty is independent of specific investment. A simple model formalizes the first case. A paradoxical dynamic of loyalty is identified: a lower degree of specificity may lead to a weakening of loyalty in the short run but astrengthening of loyalty in the long run. An application to the process of European integration is sketched.

Essays on investment, growth and income distribution

In this dissertation, I examine both theoretically and empirically the relationship between stock prices and income distribution using an endogenous growth model with social status impatience.^ The theoretical part looks into how status impatience and current economic status jointly determine time preference, savings, future economic status, stock prices, growth and wealth distribution in the steady state. This work builds on Burgstaller and Karayalcin (1996).^ More specifically, I look at (i) the effects of the distribution of status impatience levels on the distribution of steady state assets, incomes and consumption and (ii) the effects of changes in relative levels of status impatience on stock prices. Therefore, from (i) and (ii), I derive the correlation between stock prices, incomes and asset distribution. Also, the analysis of the stack market is undertaken in the presence of adjustment costs to investments.^ The empirical chapter looks at (i) the correlation between income inequality and long run economic growth on the one hand and (ii) the correlation between stock market prices and income inequality on the other. The role of stock prices and social status is examined to better understand the forces that enable a country to grow overtime and to determine why output per capita varies across countries. The data are from Summers and Heston (1988), Barro and Wolf (1989), Alesina and Rodrik (1994), Global financial Database (1997) and the World Bank. Data for social status are collected through a primary sample survey on the internet. Twenty-five developed and developing countries are included in the sample.^ The model developed in this study was specified as a system of simultaneous equations, in which per capita growth rate and income inequality were endogenous variables. Additionally, stock price index and social status measures were also incorporated. The results indicate that income inequality is inversely related to economic growth. In addition, increase in income inequality arising from higher stock prices constrains growth. Moreover, where social status is determined by income levels, it influences long run growth. Therefore, these results support findings of Persson and Tabellini (1994) and Alesina and Rodrik (1994). ^

Essays on the determinants of private investment: The effects of relative price uncertainty and political instability

The objective of this study was to provide empirical evidence on the effects of relative price uncertainty and political instability on private investment. My effort is expressed in a single-equation model using macroeconomic and socio-political data from eight Latin American countries for the period 1970–1996. Relative price uncertainty is measured by the implied volatility of the exchange rate and political instability is measured by using indicators of social unrest and political violence. ^ I found that, after controlling for other variables, relative price uncertainty and political instability are negatively associated with private investment. Macroeconomic and political stability are key ingredients for the achievement of a strong investment response. This highlights the need to develop the state and build a civil society in which citizens can participate in decision-making and express consent without generating social turmoil. At the same time the government needs to implement structural policies along with relative price adjustments to eliminate excess volatility in price movements in order to provide a stable environment for investment. ^

Social and environmental regulation of signal plasticity and signal reliability in the electric fish Brachyhypopomus gauderio

The balance between the costs and benefits of conspicuous signals ensures that the expression of those signals is related to the quality of the bearer. Plastic signals could enable males to maximize conspicuous traits to impress mates and competitors, but reduce the expression of those traits to minimize signaling costs, potentially compromising the information conveyed by the signals. ^ I investigated the effect of signal enhancement on the information coded by the biphasic electric signal pulse of the gymnotiform fish Brachyhypopomus gauderio. Increases in population density drive males to enhance the amplitude of their signals. I found that signal amplitude enhancement improves the information about the signaler's size. Furthermore, I found that the elongation of the signal's second phase conveys information about androgen levels in both sexes, gonad size in males and estrogen levels in females. Androgens link the duration of the signal's second phase to other androgen-mediated traits making the signal an honest indicator of reproductive state and aggressive motivation. ^ Signal amplitude enhancement facilitates the assessment of the signaler's resource holding potential, important for male-male interactions, while signal duration provides information about aggressive motivation to same-sex competitors and reproductive state to the opposite sex. Moreover, I found that female signals also change in accordance to the social environment. Females also increase the amplitude of their signal when population density increases and elongate the duration of their signal's second phase when the sex ratio becomes female-biased. Indicating that some degree of sexual selection operates in females. ^ I studied whether male B. gauderio use signal plasticity to reduce the cost of reproductive signaling when energy is limited. Surprisingly, I found that food limitation promotes the investment in reproduction manifested as signal enhancement and elevated androgen levels. The short lifespan and single breeding season of B. gauderio diminishes the advantage of energy savings and gives priority to sustaining reproduction. I conclude that the electric signal of B. gauderio provides reliable information about the signaler, the quality of this information is reinforced rather than degraded with signal enhancement.^

The social values of wireless technology in the institutional context

Despite growing attention, social values, compared to economic aspects, of information technology (IT) capture substantially less attention in the mainstream IT literature. In the context of mobile technology, social values might be as critical to help justify technology investment as the predominant economics perspective in the existing IT literature. As wireless networks and relevant mobile technologies continue to penetrate the global society and business world, an emerging social phenomenon rapidly reshapes how organizations interact with the technology and reposition themselves in their specific institutional context where organizations often develop networked alliance to compete against one another. This study thus seeks to shed light on how organizations make sense of the social aspects of wireless network implementation. Preliminary understanding derived from two higher education organizations' experiences is summarized. Implications for future research endeavor are suggested.

Almetrics: measuring the influence of the media on the social impact of research

Social media is changing the way we interact, present ideas and information and judge the quality of content and contributions. In recent years there have been hundreds of platforms to freely share all kinds of information and connect across networks. These new tools generate activity statistics and interactions among users such as mentions, retweets, conversations, comments on blogs or Facebook; managers references showing popularity ratings of more references shared by other researchers or repositories that generate statistics of visits or downloads of articles. This paper analyzes that have meaning and implications altmetrics, what are its advantages and critical platforms (Almetric.com, ImpactStory, Plos altmetrics, PlumX), reports progress and benefits for authors, publishers and librarians. It concluded that the value of alternative metrics as a complementary tool citation analysis is evident, although it is suggested that you should dig deeper into this issue to unravel the meaning and the potential value of these indicators to assess their potential.

Perspectives on gender, migration and transnational work: joint work of social reproduction and care in Southern Europe

This paper presents the "state of the art" and some of the main issues discussed in relation to the topic of transnational migration and reproductive work in southern Europe. We start doing a genealogy of the complex theoretical development leading to the consolidation of the research program, linking consideration of gender with transnational migration and transformation of work and ways of survival, thus making the production aspects as reproductive, in a context of globalization. The analysis of the process of multiscale reconfiguration of social reproduction and care, with particular attention to its present global dimension is presented, pointing to the turning point of this line of research that would have taken place with the beginning of this century, with the rise notions such as "global care chains" (Hochschild, 2001), or "care drain" (Ehrenreich and Hochschild, 2013). Also, the role of this new agency, now composed in many cases women who migrate to other countries or continents, precisely to address these reproductive activities, is recognized. Finally, reference is made to some of the new conceptual and theoretical developments in this area.

The trajectory of social housing policy in Brazil: From the National Housing Bank to the Ministry of the Cities

This paper discusses social housing policy in Brazil since the 1990s by analyzing government programs’ institutional arrangements, their sources of revenues and the formatting of related financial systems. The conclusion suggests that all these arrangements have not constituted a comprehensive housing policy with the clear aim of serving to enhance housing conditions in the country. Housing ‘policies’ since the 1990s – as proposed by Fernando Collor de Mello, Itamar Franco, Fernando Henrique Cardoso and ´ Luis Inacio Lula da Silva’s governments (in the latter case, despite much progress towards subsidized investment programs) – have sought to consolidate financial instruments in line with global markets, restructuring the way private interests operate within the system, a necessary however incomplete course of action. Different from rhetoric, this has resulted in failure as the more fundamental social results for the poor have not yet been achieved.

Three essays on investment in human capital in Canada

Cette thèse examine l’investissement en capital humain au Canada en s’intéressant à la contribution de l’aide financière aux études, aux effets de la fiscalité, à la rentabilité de l’investissement en éducation postsécondaire et à la redistribution des revenus. Elle est subdivisée en cinq chapitres. Le premier chapitre présente une révue chronologique des études microéconomiques sur l’investissement en capital humain. Il présente également une synthèse des études canadiennes sur l’investissement en capital humain en insistant sur les limites portant essentiellement sur la non prise en compte de l’hétérogénéité des systèmes de prêts et bourses et des systèmes fiscaux à travers les provinces canadiennes et la faible analyse de la répartition des coûts et bénéfices de l’investissement en éducation au Canada. Le second chapitre présente la méthodologie de mesure des rendements de l’éducation et des gains issus des investissements en éducation. Il décrit les données utilisées et les résultats des régressions économetriques. Finalement, le chapitre présente SIMAID, un calculateur d’aide financière aux études élaboré pour les objectifs dans cette thèse et qui permet d’estimer le montant de l’aide financière devant être attribuée à chaque étudiant en fonction de ses caractéristiques personnelles et de celles de sa famille. Dans sa première section, le troisième chapitre présente les rendements sociaux, privés et publics de l’éducation et montre que les rendements de l’éducation varient selon les provinces, les filières de formation, le genre et les cohortes d’année de naissance et décroient avec le niveau d’éducation. Dans sa seconde section, le chapitre montre que l’aide financière aux études accroît le rendement des études du baccalauréat de 24.3% et 9.5% respectivement au Québec et en Ontario. Finalement, le chapitre indique qu’un changement du système d’aide financière aux études de Québec par celui de l’Ontario entraîne une baisse de 11.9% du rendement des études au baccalauréat alors qu’un changement du système fiscal québécois par celui ontarien entraine une hausse du rendement du baccalauréat de 4.5%. L’effet combiné du changement des systèmes d’aide financière et fiscal est une baisse du rendement du baccalauréat de 7.4%. Le quatrième chapitre fournit une décomposition comptable détaillée des gains sociaux, privés et publics des investissements en éducation. Le gain social de l’investissement au baccalauréat est de $738 384 au Québec et de $685 437 en Ontario. Ce gain varie selon les filières de formation avec un niveau minimal pour les études humanitaires et un niveau maximal pour les études en ingénierie. Le chapitre montre également que la répartition des bénéfices et des coûts de l’investissement en éducation entre les individus et le gouvernement est plus équitable en Ontario qu’à Québec. En effet, un individu qui investit à Québec supporte 51.6% du coût total et engrange 64.8% des gains alors que le même individu supporterait 62.9% des coûts sociaux et engrangerait 62.2% des gains en Ontario. Finalement, le cinquième chapitre présente et analyse les effets rédistributifs des transferts et des taxes suite à un investissement en éducation. Il examine aussi si l’aide financière aux études est effectivement allouée aux personnes les plus pauvres. L’argument selon lequel l’aide financière est destinée aux plus pauvres est rejeté en analysant la distribution du revenu permanent. En effet, il ressort que 79% des personnes bénéficiant de l’aide financière aux études se trouvent dans le cinquième quintile de la distribution des revenus permanents. Le chapitre montre également que l’investissement en éducation impacte positivement les effets rédistributifs en 2006, 2001 et 1996 et négativement en 1991 et 2011. L’impact est également perceptible sur les composantes de l’effet rédistributif. Toutefois, la sensibilité de l’impact au taux d’actualisation dépend de l’indice utilisé dans l’analyse.

Gestão de Recursos Humanos no Terceiro Setor: O Caso das Instituições Particulares de Solidariedade Social

O presente trabalho tem como objetivo geral estudar a gestão de recursos humanos (GRH) no terceiro setor, focando-se especificamente nas Instituições Particulares de Solidariedade Social (IPSS). Estas organizações têm vindo a demonstrar um papel cada vez mais relevante nas comunidades em que se inserem, pela sua missão em prestar serviços de cariz social e pela atual relevância como entidades empregadoras. A diversidade presente nas IPSS ao nível da estrutura, funcionamento, dimensão, organização e dinâmicas internas, proporciona o estudo e reflexão das especificidades na GRH. Para isso, abordam-se um conjunto de aspetos: i) diferenças entre meio empresarial e terceiro setor na GRH; ii) implicações da diversidade de respostas sociais e suas especificidades na gestão de pessoas; iii) o papel do Instituto de Segurança Social e as implicações legais na gestão de pessoas; iv) a localização geográfica e acesso a recursos humanos qualificados; v) a perspetiva das IPSS sobre os recursos humanos; vi) o perfil profissional dos colaboradores das IPSS; vii) práticas quotidianas na gestão de recursos humanos nas IPSS; viii) características da GRH nas IPSS (administrativa ou estratégica); ix) responsáveis pela GRH nas IPSS; x) o papel dos órgãos sociais na GRH; xi) profissionalização versus voluntariado; xii) a GRH, certificação e qualidade; xiii) as tendências do terceiro setor na gestão de pessoas. Foi utilizada uma metodologia qualitativa e aplicada a técnica de entrevista para recolher o conhecimento, experiências e perspetivas de diferentes interlocutores do terceiro setor, dirigentes, técnicos superiores, diretores de serviço, investigadores e representantes nacionais e distritais das IPSS. Da sistematização e análise dos dados recolhidos retiraram-se várias conclusões. As pessoas são consideradas o recurso mais importante para estas organizações, pela natureza social e humana das atividades desenvolvidas, prestadas por pessoas e destinadas a pessoas. Neste sentido, é demonstrada a importância do potencial humano aquando do recrutamento e seleção, pela primazia de requisitos como o relacionamento interpessoal em detrimento das qualificações. O perfil profissional característico das IPSS reconhece a importância da polivalência, disponibilidade, comprometimento, confiança, proximidade afetiva, voluntarismo e sentido de missão dos colaboradores, os quais tendem a ser são vistos como investimento tanto quanto reúnam estes aspetos; caso contrário podem ser encarados como custo. Quanto à acessibilidade a recursos humanos, surgem diferentes modalidades, consoante fatores de localização, dimensão, formação e estrutura organizacional, bem como o fenómeno da fuga de mão de obra, indício da dificuldade em captar e reter recursos humanos. O modelo de GRH nas IPSS é de cariz tradicional, caracterizado por uma gestão porimproviso com diferentes níveis de sensibilidade e capacidade das IPSS, no que concerne à implementação de processos de GRH, tais como sistemas de progressão na carreira, recrutamento interno e sistemas de avaliação de desempenho. Quanto aos aspetos da motivação e satisfação profissional, é assumida a importância da proximidade e apoio aos colaboradores, indicativos de um sistema de recompensas informal. É percetível a resistência na aplicação de técnicas de desenvolvimento organizacional, comprovada pela limitação na formação dos quadros de colaboradores. No entanto as IPSS são confrontadas com a rigidez dos instrumentos legais. A responsabilidade pela GRH é mais ou menos partilhada entre a direção técnica e os órgãos sociais, condicionada pelo estilo de liderança e relação de confiança entre si, em norma, pouco clara quanto aos papéis e funções desempenhadas. Por fim, é percebida a necessidade de coexistência de uma gestão profissionalizada e de direções voluntárias mais capacitadas e sensibilizadas para o desenvolvimento de metodologias e estratégias de gestão de pessoas, adaptadas às especificidades das IPSS. Este trabalho pretende contribuir com um espaço de reflexão para a elaboração de respostas mais eficazes e inovadoras que proporcionem o desenvolvimento organizacional, face às necessidades e transformações do terceiro setor. / This work main objective is the study of human resource management (HRM) in the third sector. It is focused specifically on Instituições Particulares de Solidariedade Social [Private Institutions for Social Solidarity] (IPSS). These kind of organizations have demonstrated an increased value in the communities they are inserted in, by providing social care services and by generating new jobs in the local communities. The study and reflection of HRM specificities is based on the variety in the structure, the purpose, the size, the internal organization and the dynamics of the different IPSS. For this purpose we explored the following aspects : i) the differences between business community and the third sector in HRM; ii) the implications of social responses diversity in people management; iii) the role of the National Insurance Institute and the legal impact on people management; iv) the geographic location and the IPSS access to skilled human resources; v) the understanding of IPSS on human resources; vi) the professional profile of IPSS employees; vii) the daily practices in human resource management on the IPSS; viii) the characteristics of HRM in IPSS (managerial or strategic); ix) who is responsible for HRM in IPSS; x) the role of executive board in HRM; xi) professionalization versus voluntary work; xii) HRM, quality and certification; xiii) the third sector trends in people management. The qualitative method and the interview technique were applied in order to gather knowledge, experiences and perspectives from several sources such as, different partners of the third sector, managers, service directors, technicians, researchers and national and local IPSS representatives. The results indicate several conclusions. Firstly the human resources are the most important resource of IPSS organizations due to the social nature of the services provided by them but also the importance of, the individual and social, skills required for these activities that are provided by people and are directed to people. This demonstrates the importance of interpersonal skills over professional qualifications during recruitment and selection. The IPSS recognize in their professionals the importance of versatility, availability, commitment, confidence, emotional proximity, voluntarism and sense of mission. If an employee fulfills these requirements, is considered an investment; otherwise might be seen as a cost. Regarding the accessibility of IPSS to qualified human resources, we consider different models, depending on location, size and training and organizational structure as well as the phenomenon run of hand labor, defined as the index of difficulty in capturing and retaining human resources. The model of HRM in IPSS is traditional in its nature and is characterized by management based on improvisation at different levels, regarding the implementation ofHRM processes such as career advancement systems, internal recruitment and performance evaluation. In regards to motivation and job satisfaction, it is valued the proximity and the support to the employees, showing therefore an informal system of rewards. There is a noticeable resistance to the application of organizational techniques which is demonstrated by controlling the formation of employees. However the IPSS are required to face the rigidity of legal instruments. The responsibility for HRM is shared between the technical direction and the management bodies, which depends on leadership style and mutual trust, and is generally unclear about the roles and duties performed. Finally, it becomes evident the need for coexistence between a professional management and a voluntary management, more capable and more sensible to the development of methods and strategies for people management, specifically adapted to each IPSS. This paper aims to contribute with space for reflection in the development of more effective and innovative responses for the organizational development, given the needs and transformations of the third sector.

Social Capital in Jordan: Wasta in Employment Selection

Social capital has emerged as a concept of great interest and potential to help understand and explain how social structures and networks impact political, social and business practices at the collective and individual levels. The basic premise is: investment in social relations will yield expected returns. Extant research has largely focused on the West; our knowledge of how social capital plays out in the Middle East is limited. We marry social capital with ‘wasta’, the strong family and tribal based connections secured in networks in the Arab world, and investigate HR managers’ perceptions of wasta in employment selection in Jordan. Often use of wasta in employment selection is related to favouritism and nepotism and the many negative outcomes of not adhering to merit-based selection. Through in-depth interview data we reveal a more nuanced and multifaceted view of wasta in employment selection. When examined through the social capital lens six distinct themes emerge: (i) wasta as an enabler to get jobs, (ii) wasta as social ties/ solidarity, (iii) wasta as a method to transfer/ attain information, (iv) wasta as a guide in decision-making, (v) wasta as an exchange, and (vi) wasta as pressure. Our findings confirm that at times wasta grants individuals unfair access to employment that is beyond their qualifications, skills, knowledge and/ or abilities. However, organisational context is relevant. In banking, not all roles are open to wasta. Where the possible negative impact on the organisation poses too great a risk HR managers feel able to resist even strong wasta. Context also emerges as being of key importance with regards to the background and business model of an organisation. Family businesses tend to operate wasta more frequently and extensively using tribal connections, religious networks and geographical area based networks as a key source in hiring. Despite globalisation and international nature of banking, wasta and tribalism feature strongly in daily business conduct in Jordan. Our paper illuminates the positive effects of wasta, e.g.as a method to transfer information, together with discussion on the dangers of ‘cloning’, a (lack of diversity), and the dangers of an incompetent workforce .
