The note “Efficiency in a Monotonic Partnership with Investment: An endogenous implementation of Holmström’s Principal” has been accepted for publication in the September 2015 issue of Bulletin of Business and Economics.

Abstract:
This note presents a model of a partnership that requires initial investment. The production technology depends on partners’ effort choices and, possibly, on an exogenous stochastic term. When the technology is monotonic, the paper shows that the need for an investor is a sufficient condition to ensure efficiency. Efficient sharing rules arise endogenously as outcomes of optimal contracts between the investor and the partners. This result illustrates how a Principal-agent structure can naturally arise in a partnership, without changing its basic internal structure. Indeed, the investor emerges as an (external) implementation of a budget-breaker Principal that solves the inefficiency problem inherent to partnerships, as suggested in Holmström (1982).

The paper “Lei de Benford para a Auditoria de Obras Públicas; Análise de Sobrepreço na Construção da Arena da Amazônia” has been published in BLC – Boletim de Licitações e Contratos published by NDJ.

The paper applies a methodology based on Benford’s Law to analyze the UNIT PRICES’ woksheet for the construction of the Amazon Arena 2014 FIFA World Cup Stadium.

The short article: ブラジルの環境問題と環境省人事 (Environment issues in Brazil and turnover in the Brazilian Ministry of the Environment), coauthored with Keiichi Yamazaki, has been accepted for publication in the September 2015 issue of ブラジル特報 (Burajiru Tokuhou – Brazil Dispatch), a publication of the Central Nipo-Brazilian Association (Associação Central Nipo-Brasileira), Tokyo, Japan.

The article “Should Voting Be Mandatory? The effect of compulsory voting rules on candidates’ political platforms” has been published as the leading article of issue 18(1) of the Journal of Applied Economics.
The article will be shortly included by Elsevier BV in their online platform Science Direct http://www.sciencedirect.com/science/journal/15140326

The article “Benford’s law for audit of public works: an analysis of overpricing in Maracanã soccer arena’s renovation” has been published in Economics Bulletin.

I was saddened today by the terrible news of the death of John and Alicia Nash.

In addition to  the well known, fantastic contributions of Nash’s genius to Mathematics and Economic Theory, John and Alicia Nash where the living proof that Love, Patience, Dedication and Companionship are among the most beautiful expressions of human spirit.

This is surely why you were allowed the rest together…

We will miss you!
