This article brings new inputs to debate outsourcing in Brazil, using a new methodology based on administrative records. With this methodology, it is possible to identify 4.02 million outsourced workers, corresponding to 11.7% of total employees in the urban private sector. Moreover, with this...

This paper estimates the conditional volatility of the main Brazilian stock market index (Ibovespa), using traditional models of the GARCH family and models of stochastic volatility (SV). Most model selection and performance criteria suggest that both aproaches capture well Ibovespa's...

The technological and institutional environment influences the way of doing research and the relationships between its participants. Intellectual property is a strategic issue to build the institutional framework of the new technological regime and therefore the dynamics of innovation in...

In this work we consider modeling the past volatilities through a Generalized Autoregressive Conditional Heteroskedasticity (GARCH) model using the Bayesian approach. Asymmetries in the shocks are accommodated by smooth transition models for the variance. We discuss problems related to the...

Wind power generation is essential to reduce the use of fossil resources and, consequently, the emission of greenhouse gases (GHG). Currently, the National Interconnected System (SIN) has about 9971 wind turbines in operation, the sixth largest network in the world ranking, and 80% of Brazilian...

This work presents a Bayesian approach for inferring the capacity factor of an offshore wind farm. The application of the proposed methodology is illustrated through a case study of a wind power offshore project located on the northern coast of the Rio de Janeiro State.

This paper presents a brief literature review concerning the costs and benefits of electric vehicles and hybrid electric vehicles, highlighting their advantages in terms of greenhouse gas emissions reductions. Even though electric and electro-hybrid vehicles must still overcome many cultural and...
