Inflation and income inequality: A link through the job-search process

In this paper I devise a new channel by means of which the (empirically documented) positive correlation between ináation and income inequality can be understood. Available empirical evidence reveals that ináation increases wage dispersion. For this reason, the higher the ináation rate, the higher turns out to be the beneÖt, for a worker, of making additional draws from the distribution of wages, before deciding whether to accept or reject a job o§er. Assuming that some workers have less access to information (wage o§ers) than others, I show that the Gini coe¢ cient of income distribution turns out to be an increasing function of the wage dispersion and, consequently, of the rate of ináation. Two examples are provided to illustrate the mechanism.

Responsabilidade social empresarial do varejo no Brasil: um estudo, multi casos em empresas de grande porte

O estudo busca investigar a atuação das grandes empresas varejista brasileiras com relação à Responsabilidade Social Empresarial (RSE), procurando levantar o estágio em que estas se encontram, e se são aproveitadas as características do varejo de capilaridade geográfica, contato direto com a comunidade, forte vinculo com os clientes, interação entre funcionários e clientes e proximidade física de Organizações Não Governamentais e instituições públicas. Para tanto, foram utilizados conceitos relacionados à gestão, como comprometimento da cúpula, incorporação de valores de RSE na administração e no planejamento estratégico, autonomia e gestão de RSE nas lojas. A gestão foi avaliada pela ótica do contínuo de colaboração de Austin, e as práticas de RSE por meio da teoria dos stakeholders (públicos interessados), utilizando como base as dimensões dos Indicadores Ethos de Responsabilidade Social. A teoria de Kotler e Lee, para a classificação das iniciativas conforme os conceitos do marketing, também foi empregada. Conduziu-se uma pesquisa exploratória com cinco grandes empresas do setor varejista. Os resultados encontrados apontam que na maioria das empresas a incorporação dessas práticas é recente. Constata-se que as empresas diferem quanto ao estágio de RSE e que as características próprias do varejo não são aproveitadas em sua totalidade. Hipóteses são levantadas para que estas aproveitem a estrutura das lojas para atender às necessidades da comunidade local.

The missing link: using the NBER recession indicator to construct coincident and leading indices economic activity

We use the information content in the decisions of the NBER Business Cycle Dating Committee to construct coincident and leading indices of economic activity for the United States. We identify the coincident index by assuming that the coincident variables have a common cycle with the unobserved state of the economy, and that the NBER business cycle dates signify the turning points in the unobserved state. This model allows us to estimate our coincident index as a linear combination of the coincident series. We establish that our index performs better than other currently popular coincident indices of economic activity.

Board of directors and top management team: a study on CEO relative power and financial return

Best corporate governance practices published in the primers of Brazilian Securities and Exchange Commission and the Brazilian Corporate Governance Institute promote board independence as much as possible, as a way to increase the effectiveness of governance mechanism (Sanzovo, 2010). Therefore, this paper aims at understanding if what the managerial literature portraits as being self-evident - stricter governance, better performance - can be observed in actual evidence. The question answered is: do companies with a stricter control and monitoring system perform better than others? The method applied in this paper consists on comparing 116 companies in respect to the their independence level between top management team and board directors– being that measured by four parameters, namely, the percentage of independent outsiders in the board, the separation of CEO and chairman, the adoption of contingent compensation and the percentage of institutional investors in the ownership structure – and their financial return measured in terms return on assets (ROA) from the latest Quarterly Earnings release of 2012. From the 534 companies listed in the Stock Exchange of Sao Paulo – Bovespa – 116 were selected due to their level of corporate governance. The title “Novo Mercado” refers to the superior level of governance level within companies listed in Bovespa, as they have to follow specific criteria to assure shareholders ´protection (BM&F, 2011). Regression analyses were conducted in order to reveal the correlation level between two selected variables. The results from the regression analysis were the following: the correlation between each parameter and ROA was 10.26%; the second regression analysis conducted measured the correlation between the independence level of top management team vis-à-vis board directors – namely, CEO relative power - and ROA, leading to a multiple R of 5.45%. Understanding that the scale is a simplification of the reality, the second part of the analysis transforms all the four parameters into dummy variables, excluding what could be called as an arbitrary scale. The ultimate result from this paper led to a multiple R of 28.44%, which implies that the combination of the variables are still not enough to translate the complex reality of organizations. Nonetheless, an important finding can be taken from this paper: two variables (percentage of outside directors and percentage of institutional investor ownership) are significant in the regression, with p-value lower than 10% and with negative coefficients. In other words, counter affirming what the literature very often portraits as being self-evident – stricter governance leads to higher performance – this paper has provided evidences to believe that the increase in the formal governance structure trough outside directors in the board and ownership by institutional investor might actually lead to worse performance. The section limitations and suggestions for future researches presents some reasons explaining why, although supported by strong theoretical background, this paper faced some challenging methodological assumptions, precluding categorical statements about the level of governance – measured by four selected parameters – and the financial return in terms of financial on assets.

Determinação química e biológica de bauhinia forficata link subespécie pruinosa (pata-de-vaca - leguminosae)

Bauhinia forficata, Leguminosae, é conhecida popularmente como pata-devaca e seus principais constituintes químicos são flavonóides. Ë comumente usada como antidiabética, mas existem relatos a respeito de suas atividades antioxidante e antiedematogênica. A fim de avaliar-se o comportamento de seus constituintes químicos frente a variações de temperatura e umidade, realizou-se estudo de estabilidade acelerada (50 ºC ± 2 oC e 90% ± 5% U.R.), onde a substância química majoritária (SQM) serviu como marcador para os devidos cálculos e, portanto, o seu isolamento prévio tornou-se imprescindível. Um método devidamente validado por Cromatografia Líquida de Alta Eficiência (CLAE) foi utilizado para as análises e através das mesmas pode-se predizer uma reação de segunda ordem e, por conseguinte, um tempo de vida útil de 2,63 dias e um tempo de meia-vida de 23,65 dias. Avaliou-se, ainda, as atividades antioxidante (DPPH), antiedematogênica (edema em pata de ratos induzido pela carragenina) e anticolinesterásica (autobiografia). Para a atividade antioxidante, dos extratos testados, o butanólico foi o que demonstrou maior ação (54,73 µl/ml) sendo, no entanto, inferior ao padrão Ginkgo biloba (42,51 µl/ml). Na avaliação da atividade antiedematogênica, o extrato aquoso testado demonstrou um máximo de inibição de 76,5%. Ao testar-se a atividade anticolinesterásica de produtos isolados obtidos a partir de B. forficata, nenhuma ação significativa foi observada exigindo estudos complementares.

The relationship between board of director's nationality diversity and financial performance

Companies are moving to a more international structure; going into new markets and having an increased competition in all fronts. Therefore, the practices that lead companies to a more efficient and competitive position are praised. The management of the workforce comes as one of the main concerns of companies, aiming at performance enhancing and at creating better environments that both attract and maintain the professional talents. In an increasingly international environment, companies tend to look for the specialists and best professionals, regardless of their nationality. This new structure with several different nationalities working together poses new challenges for companies. Understanding if and how a more diverse has a relationship with financial performance is the starting point for better managing this new corporate structure.

Modeling and predicting the CBOE market volatility index

This paper performs a thorough statistical examination of the time-series properties of the daily market volatility index (VIX) from the Chicago Board Options Exchange (CBOE). The motivation lies not only on the widespread consensus that the VIX is a barometer of the overall market sentiment as to what concerns investors' risk appetite, but also on the fact that there are many trading strategies that rely on the VIX index for hedging and speculative purposes. Preliminary analysis suggests that the VIX index displays long-range dependence. This is well in line with the strong empirical evidence in the literature supporting long memory in both options-implied and realized variances. We thus resort to both parametric and semiparametric heterogeneous autoregressive (HAR) processes for modeling and forecasting purposes. Our main ndings are as follows. First, we con rm the evidence in the literature that there is a negative relationship between the VIX index and the S&P 500 index return as well as a positive contemporaneous link with the volume of the S&P 500 index. Second, the term spread has a slightly negative long-run impact in the VIX index, when possible multicollinearity and endogeneity are controlled for. Finally, we cannot reject the linearity of the above relationships, neither in sample nor out of sample. As for the latter, we actually show that it is pretty hard to beat the pure HAR process because of the very persistent nature of the VIX index.

Measurements of income inequality: a critique. Inflation and income inequality: a link through the job- search process

In this paper I claim that, in a long-run perspective, measurements of income inequality, under any of the usual inequality measures used in the literature, are upward biased. The reason is that such measurements are cross-sectional by nature and, therefore, do not take into consideration the turnover in the job market which, in the long run, equalizes within-group (e.g., same-education groups) inequalities. Using a job-search model, I show how to derive the within-group invariant-distribution Gini coefficient of income inequality, how to calculate the size of the bias and how to organize the data in arder to solve the problem. Two examples are provided to illustrate the argument.
