Biased managers, organizational design, and incentive provision

We model the tradeoff between the balance and the strength of incentives implicit in the choice between hierarchical and matrix organizational structures. We show that managerial biases determine which structure is optimal: hierarchical forms are preferred when biases are low, while matrix structures are preferred when biases are high.

Do dividends signal more earnings?

Signaling models have contributed to the corporate finance literature by formalizing "the informational content of dividends" hypothesis. However, these models are under criticism of empirical literature, as weak evidences were found supporting one of the main predicitions: the positive relation between changes in dividends and changes in earnings. We claim thaht the failure to verify this prediction does not invalidate the signaling approach. The models developed up to now assume or derive utility functions with the single-crossing property. We show thaht signaling is possible in the absence of this property and, in this case, changes in dividend and changes in earnings can be positively or negatively related.

Mudanças na distribuição dos rendimentos da população ocupada brasileira

A distribuição dos rendimentos da população ocupada brasileira sofreu nos últimos anos, alterações consideráveis, a partir dos novos requisitos exigidos para a contratação da mão-de-obra ou para a remuneração de autônomos, tendo em vista os renovados processos produtivos e organizacionais, bem como as políticas econômicas conjunturais voltadas para a estabilização. A pesquisa visa contribuir com subsídios para a análise dos impactos das transformações recentes na composição dos rendimentos médios do trabalhador brasileiro, observando-se as situações nas condições de trabalho com ou sem carteira assinada, segundo o gênero, dentro e fora de empresas. Nas empresas é analisada a composição dos rendimentos segundo a segmentação do mercado de trabalho e a qualificação.

Perfil dos trabalhadores por conta própria no Brasil

O objetivo global desta pesquisa foi contribuir com subsídios para a análise das características do trabalhador brasileiro por conta própria ou autônomo, particularmente no que se refere ao padrão de distribuição setorial, ocupacional e dos rendimentos da população ocupada, tendo em vista os novos requisitos demandados pelos atuais processos produtivos e organizacionais, dentro e fora das empresas. Estas características são retratadas pela representatividade ocupacional dos trabalhadores detalhando particularmente as diferenças segundo a segmentação setorial, nível de escolaridade, rendimentos, número de horas trabalhadas por semana e gênero, analisando as informações disponíveis para o ano de 1997.

Organizational design as an enabler for innovation: evidence from a German Mechanical Engineering Company

Over the past two decades there has been a profusion of empirical studies of organizational design and its relationship to efficiency, productivity and flexibility of an organization. In parallel, there has been a wide range of studies about innovation management in different kind of industries and firms. However, with some exceptions, the organizational and innovation management bodies of literature tend to examine the issues of organizational design and innovation management individually, mainly in the context of large firms operating at the technological frontier. There seems to be a scarcity of empirical studies that bring together organizational design and innovation and examine them empirically and over time in the context of small and medium sized enterprises. This dissertation seeks to provide a small contribution in that direction. This dissertation examines the dynamic relationship between organizational design and innovation. This relationship is examined on the basis of a single-case design in a medium sized mechanical engineering company in Germany. The covered time period ranges from 1958 until 2009, although the actual focus falls on the recent past. This dissertation draws on first-hand qualitative empirical evidence gathered through extensive field work. The main findings are: 1. There is always a bundle of organizational dimensions which impacts innovation. These main organizational design dimensions are: (1) Strategy & Leadership, (2) Resources & Capabilities, (3) Structure, (4) Culture, (5) Networks & Partnerships, (6) Processes and (7) Knowledge Management. However, the importance of the different organizational design dimensions changes over time. While for example for the production of simple, standardized parts, a simple organizational design was appropriate, the company needed to have a more advanced organizational design in order to be able to produce customized, complex parts with high quality. Hence the technological maturity of a company is related to its organizational maturity. 2. The introduction of innovations of the analyzed company were highly dependent on organizational conditions which enabled their introduction. The results of the long term case study show, that some innovations would not have been introduced successfully if the organizational elements like for example training and qualification, the build of network and partnerships or the acquisition of appropriate resources and capabilities, were not in place. Hence it can be concluded, that organizational design is an enabling factor for innovation. These findings contribute to advance our understanding of the complex relationship between organizational design and innovation. This highlights the growing importance of a comprehensive, innovation stimulating organizational design of companies. The results suggest to managers that innovation is not only dependent on a single organizational factor but on the appropriate, comprehensive design of the organization. Hence manager should consider to review regularly the design of their organizations in order to maintain a innovation stimulating environment.

The effects of adult literacy on earnings and employment

This paper provides evidence of the effects of adult literacy on individuals’ income and employability in Brazil based on information obtained from the monthly employment survey (PME). The OLS results indicate that after controlling for observable characteristics, there is a 21.25% increase in wages for individuals who become literate; however, there is no significant impact on employability. Moreover, the findings show an 8.1% increase in the probability of being employed in the formal sector. We also explore the longitudinal structure of the dataset to control for unobservable fixed characteristics of individuals. The fixed-effects estimators show smaller effects compared to the OLS estimators. We find that literacy has a 4.4% effect on wages and a 4.3% impact on the probability of being formally employed. The effects are significantly different from zero.

A evolução do Programa Pró-Equidade de Gênero: 2005-2013

A divisão sexual do trabalho é algo que ainda predomina no mercado laboral e nas organizações. As diferenças entre os salários pagos a homens e mulheres em funções análogas, a maioria de homens presentes nos altos cargos de liderança e de tomada de decisão, a miséria relacionada à dificuldade de acesso das mulheres à saúde e à educação são alguns fatores que justificam a importância das políticas de empoderamento para as mulheres. Neste sentido, desde 2005 vem sendo implementado o Programa Pró-Equidade de Gênero e Raça, da Secretaria de Políticas para Mulheres, cujo objetivo principal é combater as desigualdades entre os gêneros e as raças, promovendo boas práticas no mundo do trabalho, em organizações públicas e privadas. Essa pesquisa aborda, de forma sucinta, a evolução deste programa por meio da concessão do Selo Pró-Equidade às Organizações Públicas e Privadas, no período de 2005 a 2013.

The effects of the minimum wage on earnings and employment in Brazil

This paper analyzes the effects of the mlmmum wage on both, eammgs and employment, using a Brazilian rotating panel data (Pesquisa Mensal do Emprego - PME) which has a similar design to the US Current Population Survey (CPS). First an intuitive description of the data is done by graphical analysis. In particular, Kemel densities are used to show that an increase in the minimum wage compresses the eamings distribution. This graphical analysis is then forrnalized by descriptive models. This is followed by a discussion on identification and endogeneity that leads to the respecification of the model. Second, models for employment are estimated, using an interesting decomposition that makes it possible to separate out the effects of an increase in the minimum wage on number of hours and on posts of jobs. The main result is that an increase in the minimum wage was found to compress the eamings distribution, with a moderately small effect on the leveI of employment, contributing to alleviate inequality.

Trade liberalization and the evolution of skill earnings differentials in Brazil

From 1988 to 1995, when trade liberalization was implemented in Brazil, relative earnings of skilled workers decreased. In this paper, we investigate the role of trade liberalization in explaining these relative earnings movements, by checking all the steps predicted by the HeckscherOhlin- style trade transmission mechanism. We find that: i) employment shifted from skilled to unskilled intensive sectors, and each Sector increased its relative share of skilled labor; ii) relative prices fell in skill intensive sectors; iii) tariff changes across sectors were not related to skill intensities, but the pass-through from tariffs to prices was stronger in skill intensive sectors; iv) the decline in skilled eamings differentials mandated by the price variation predicted by trade is very elose to the observed one. The results are compatible with trade liberalization, accounting for the observed rei ative eamings changes in Brazil.

Earnings dynamics and inequality in Venezuela: 1995-1997

In this paper, we decompose the variance of logarithmic monthly earnings of prime age males into its permanent and transitory components, using a five-wave rotating panel from the Venezuelan “Encuesta de Hogares por Muestreo” from 1995 to 1997. As far as we know, this is the first time a variance components model is estimated for a developing country. We test several specifications and find that an error component model with individual random effects and first order serially correlated errors fits the data well. In the simplest model, around 22% of earnings variance is explained by the variance of permanent component, 77% by purely stochastic variation and the remaining 1% by serial correlation. These results contrast with studies from industrial countries where the permanent component is predominant. The permanent component is usually interpreted as the results of productivity characteristics of individuals whereas the transitory component is due to stochastic perturbations such as job and/or price instability, among others. Our findings may be due to the timing of the panel when occurred precisely during macroeconomic turmoil resulting from a severe financial crisis. The findings suggest that earnings instability is an important source of inequality in a region characterized by high inequality and macroeconomic instability.

Is child labor harmful? the impact of working as a child on adult earnings

This paper explores the question: is working as young laborer harmful to an individual in terms of adult outcomes in income? This question is explored through the utilization of a unique set of instruments that control for the decision to work as a child and the decision of how much schooling to acquire. These instruments are combined with two large household survey data sets from Brazil that include retrospective information on the child labor and schooling of working-age adults: the 1988 and 1996 PNAD. Estimations of the reduced form earnings model are performed first by using OLS without controlling for the potential endogeneity of child labor and schooling, and then by using a GMM estimation of instrumental variables models that include the set of instruments for child labor and schooling. The findings of the empirical investigations show that child labor has large negative impact on adult earnings for both male and female children even when controlling for schooling. In addition, the negative impact of starting to work as a child reverses at around age 14. Finally, different child labor activities are examined to determine if some are beneficial while others harmful with the finding that working in agriculture as a child appears to have no negative impact over and above the loss of education.
