Taylor principle and inflation stability in emerging market countriesw

The goal of this paper is to evaluate the validity of the Taylor principle for inflation control in 12 developing countries that use inflation targeting regimes: Brazil, Chile, Colombia, Hungary, Israel, Mexico, Peru, Philippines, Poland, South Africa, Thailand and Turkey. The test is based on a state-space model to determine when each country has followed the principle; then a threshold unit root test is used to verify if the stationarity of the deviation of the expected inflation from its target depends on compliance with the Taylor principle. The results show that such compliance leads to the stationarity of the deviation of the expected inflation from its target in all cases. Furthermore, in most cases, non-compliance with the Taylor principle leads to nonstationary deviation of the expected inflation.

Administração pública federal: propostas para o fortalecimento do controle sobre os atos praticados e o respectivo combate à corrupção

The characteristics of the Brazilian historic context, under which the predominant social relations have developed, have led to a process of income concentration and to the political power of the dominant classes. The slavery abolishment hasn't guaranteed the people the rights secured to privileged citizens in general. Such practices were observed during historic process as the low level literacy shown by the census of 1920, the political domination of oligarchies and the military coup, all as determining factors in process of political power concentration. The social indicators and the corruption are extremely unfavorable to our country, but we wonder if that happens only in underdeveloped societies. It is possible that even the American society, even the most developed societies, under the democratic capitalism, can suffer negative consequences of some corruption in the capitalism system. Our observations have led to the perception that all democratic society must be regulated by the State in order to preserve the stability of the system. It has also been observed that it is necessary more effective popular participation in order to neutralize economic groups¿ pressure. It has also become evident the necessity of reduction of commissioned office in the federal public administration. And, finally, it is fundamental to propose an amendment to the construction that allows the Public Ministry to have access to any bank, fiscal or telephonic information of anyone that is in office: It should be called "The Law of Moral Transparency". Those proposals will only be possible if there is massive popular participation and we hope that they express our people¿s will in order to appose to those who act only to obtain private benefits.

Information learning and the stability of fiat money

We analyze the stability of monetary regimes in a decentralized economy where fiat money is endogenously created, information about its value is imperfect, and agents only learn from their personal trading experiences. We show that in poorly informed economies, monetary stability depends heavily on the government's commitment to the long run value of money, whereas in economies where agents gather information more easily, monetary stability can be an endogenous outcome. We generate a dynamics on the acceptability of fiat money that resembles historical accounts of the rise and eventual colIapse of overissued paper money. Moreover, our results provide an explanation of the fact that, despite its obvious advantages, the widespread use of fiat money is a very recent development.
