O reforço das competências de gestão nas instituições públicas: governança e gestão no poder legislativo municipal: estudo de caso na Câmara Municipal de Niterói

This thesis analyzes the governance in public institutions management, taking the Niteroi's Cityzenship Council as the reasearch object. In order to accomplish this goal, this thesis has been split into two parts. The first one introduces the discussion about management, manager's action and administration, differentiating the private approach from the public one. The characteristics of the public service and its models were defined, as they were incorporated in the last decades in parallel with the institutionalism and governance theories. In the second part a description is presented on the Brazilian's politician space construction, with emphasis in the cities and in the functioning of the public institutions according to the reality of the Brazilian's partisan system. The concept of accountability and the relation between repuplican powers were also discussed, followed by a case study. The analyses show the reality of the governance at the chamber of the councilmen of Niteroi in accordance with the methodology chosen to accomplishment the research. The conclusion points out the findings that were obtained during the research.

Retail competition and shelf space allocation

We develop a model to study shelf space allocation in retail. Retailers compete for consumers not only choosing prices but also by the space allocated to each product on shelves. Our approach depart from the existing literature on shelf allocation, as we model the problem of price setting and shelf allocation in an oligopolistic retail market. We present a simple model of retail competition in which prices are dispersed in the crosssection of stores but shelf allocation is not.

Approximate recursive equilibrium with minimal state space

This paper shows existence of approximate recursive equilibrium with minimal state space in an environment of incomplete markets. We prove that the approximate recursive equilibrium implements an approximate sequential equilibrium which is always close to a Magill and Quinzii equilibrium without short sales for arbitrarily small errors. This implies that the competitive equilibrium can be implemented by using forecast statistics with minimal state space provided that agents will reduce errors in their estimates in the long run. We have also developed an alternative algorithm to compute the approximate recursive equilibrium with incomplete markets and heterogeneous agents through a procedure of iterating functional equations and without using the rst order conditions of optimality.

Estimating Brazilian Monthly GDP: a State-Space Approach

This paper has several original contributions. The first is to employ a superior interpolation method that enables to estimate, nowcast and forecast monthly Brazilian GDP for 1980-2012 in an integrated way; see Bernanke, Gertler and Watson (1997, Brookings Papers on Economic Activity). Second, along the spirit of Mariano and Murasawa (2003, Journal of Applied Econometrics), we propose and test a myriad of interpolation models and interpolation auxiliary series- all coincident with GDP from a business-cycle dating point of view. Based on these results, we finally choose the most appropriate monthly indicator for Brazilian GDP. Third, this monthly GDP estimate is compared to an economic activity indicator widely used by practitioners in Brazil - the Brazilian Economic Activity Index - (IBC-Br). We found that the our monthly GDP tracks economic activity better than IBC-Br. This happens by construction, since our state-space approach imposes the restriction (discipline) that our monthly estimate must add up to the quarterly observed series in any given quarter, which may not hold regarding IBC-Br. Moreover, our method has the advantage to be easily implemented: it only requires conditioning on two observed series for estimation, while estimating IBC-Br requires the availability of hundreds of monthly series. Third, in a nowcasting and forecasting exercise, we illustrate the advantages of our integrated approach. Finally, we compare the chronology of recessions of our monthly estimate with those done elsewhere.

Avenues to success : electoral strategies and ambition in the Brazilian chamber of deputies

In the second consecutive election for the Brazilian Chamber ofDeputies, the majority of incumbents (75% in 1998 and again 75% in 2002) decided to run for reelection and at least 70% ofthem in both elections were successful, suggesting thus it would be incorrect to ignore static ambition as the main target of Brazilian legislators. It also raises doubts about the assertion that incumbents use their posts to pursue their post-Iegislative careers. However, this number also suggests that not alIlegislators seek reelection, indicating that it is also incorrect to assume alI of them are driven by similar motivations. In their attempts at career survival, incumbents may also run for higher offices (Senator, Governor, Vicegovernor). A minority still, may run for state leveI offices (regressive ambition).Given that static and progressive ambition are the two main types of career choice in Brazil, we focus on the factors that influence the career decision and electoral success of those who choose to run for reelection and those who choose to run for higher-level offices, i.e. senator and governor. We use data recently colIected from the 2002 elections.
