O efeito smart money na indústria de fundos brasileira

O presente trabalho estuda o efeito Smart Money, inicialmente identificado por GRUBER(1996) e ZHENG (1999), na indústria de fundos brasileira no período de 2001 a 2005. Buscou-se identificar se os fundos que apresentaram maior captação líquida em seguida performam melhor do que os fundos de menor captação líquida. O efeito Smart Money foi identificado nos fundos de ações mesmo após ter sido controlado pelo efeito momentum. Nos fundos multimercados com renda variável e nos fundos de renda fixa não foi possível identificar tal fenômeno.

Limited memory and the essentiality of money

This paper investigates the relationship between memory and the essentiality of money. We consider a random matching economy with a large finite population in which commitment is not possible and memory is limited in the sense that only a fraction m E(0; 1) of the population has publicly observable histories. We show that no matter how limited memory is, there exists a social norm that achieves the first best regardless of the population size. In other words, money can fail to be essential irrespective of the amount of memory in the economy. This suggests that the emphasis on limited memory as a fundamental friction for money to be essential deserves a deeper examination.

Money versus memory

A well–established fact in monetary theory is that a key ingredient for the essentiality of money is its role as a form of memory. In this paper we study a notion of memory that includes information about an agent’s past actions and trading opportunities but, in contrast to Kocherlakota (1998), does not include information about the past actions and trading opportunities of an agent’s past partners. We first show that the first–best can be achieved with memory even if it only includes information about an agent’s very recent past. Thus, money can fail to be essential even if memory is minimal. We then establish, more interestingly, that if information about trading opportunities is not part of an agent’s record, then money can be better than memory. This shows that the societal benefit of money lies not only on being a record of past actions, but also on being a record of past trading opportunities, a fact that has been overlooked by the monetary literature.

Money supply and capital accumulation on the transition path revisited

Fischer (1979) and Asako (1983) analyze the sign of the correlation between the growth rate of money and the rate of capital accumulation on the transition path. Both plug a CRRA utility (based on a Cobb-Douglas and a Leontief function, respectively) into Sidrauski's model - yet return contrasting results. The present analysis, by using a more general CES utility, presents both of those settings and conclusions as limiting cases, and generates economic gures more consistent with reality (for instance, the interest-rate elasticity of the money demands derived from those previous works is necessarily 1 and 0, respectively).

Divisia indexes, money and welfare

We suggest the use of a particular Divisia index for measuring welfare losses due to interest rate wedges and in‡ation. Compared to the existing options in the literature: i) when the demands for the monetary assets are known, closed-form solutions for the welfare measures can be obtained at a relatively lower algebraic cost; ii) less demanding integrability conditions allow for the recovery of welfare measures from a larger class of demand systems and; iii) when the demand speci…cations are not known, using an index number entitles the researcher to rank di¤erent vectors of opportunity costs directly from market observations. We use two examples to illustrate the method.

Sistemas monetarios alternativos

This paper is a collection of surveys about alternative monetary systems. It hegins with metalic anda comondity monetary systems. Keeping this line of evolution, the next step is the study of 100% covered emissions like the currency boards and the extreme of the abolition of no national money. The last article concerns the Hayek of the desnationalization of money.

Parceria público-privada na saúde no Brasil: estudo de caso do Hospital do Subúrbio de Salvador - Bahia

O presente trabalho tem como objetivo caracterizar o processo de decisão e implementação da Parceria Público-Privada da Saúde na Bahia – Hospital do Subúrbio. A metodologia utilizada foi a pesquisa qualitativa, na modalidade de estudo de caso, direcionada a compreender esse caso, através da narrativa dos principais stakeholders, de análise documental e da bibliografia nacional e internacional sobre o tema, desde textos legais até relatos de experiências internacionais. Com isso, pretende-se contribuir para o maior conhecimento e entendimento da PPP como uma nova modalidade institucional para a gestão da saúde, documentando um momento ainda inicial desse processo. Os resultados apontam que as principais condicionantes para a contratação de PPP, conforme a literatura internacional, foram atendidas: Análise Value for Money (VFM), elaboração de edital e contrato, licitação, formação de Sociedade de Propósito Específico (SPE), Fundo Garantidor de PPP. Analisando os pontos centrais na Nova Gestão Pública – gestão para resultados, construção de um modelo organizacional mais flexível e accountability – foi possível concluir que o projeto do Hospital do Subúrbio está alinhado com os princípios da gestão pública contemporânea. No entanto, é preciso amadurecer principalmente a accountability e seguir o caso para acompanhar seus resultados.

Coordination in the use of money

Fundamental models of money, while explicit about the frictions that render money essential, are silent on how agents actually coordinate in its use. This paper studies this coordination problem, providing an endogenous map between the primitives of the environment and the beliefs on the acceptability of money. We show that an increase in the frequency of trade meetings, besides its direct impact on payo¤s, facilitates coordination. In particular, for a large enough frequency of trade meetings, agents always coordinate in the use of money.

Money distribution with intermediation

This pap er analyzes the distribution of money holdings in a commo dity money search-based mo del with intermediation. Intro ducing heterogeneity of costs to the Kiyotaki e Wright ( 1989 ) mo del, Cavalcanti e Puzzello ( 2010) gives rise to a non-degenerated distribution of money. We extend further this mo del intro ducing intermediation in the trading pro cess. We show that the distribution of money matters for savings decisions. This gives rises to a xed p oint problem for the saving function that di cults nding the optimal solution. Through some examples, we show that this friction shrinks the distribution of money. In contrast to the Cavalcanti e Puzzello ( 2010 ) mo del, the optimal solution may not present the entire surplus going to the consumer. At the end of the pap er, we present a strong result, for a su cient large numb er of intermediaries the distribution of money is degenerated.

Social norms and money

In an economy where there is no double coincidence of wants and without recordkeeping of past transactions, money is usually seen as the only mechanism that can support exchange. In this paper, we show that, as long as the population is finite and agents are sufficiently patient, a social norm establishing gift-exchange can substitute for money. Notwithstanding, for a given discount factor, the growth of the population size eventually leads to the breakdown of the social norm, while money still works. 1 Introduction

WeIfare costs of inflation the case for interest-bearing money and empiricaI Estimates for Brazil

We provide in this paper a closed fonn for the Welfare Cost of Inflation which we prove to be closer than Bailey's expression to the correct solution of the corresponding non-separable differential equation. Next, we extend this approach to an economy with interest-bearing money, once again presenting a better appoximation than the one given by Bailey's approach. Finally, empirical estimates for Brazil are presented.
