New models of old(?) payment questions

Is private money feasible and desirable? In its absence, is there a central bank policy that partially or fully substitutes for private money? In this paper, some recent modeling ideas about how to address these questioned are reviewed and applied. The main ideas are that people cannot commit to future actions and that their histories are to some extent unknown - are not common knowledge. Under the additional assumption that the private monies issued by diferent people are distinct, a strong recognizability assumption, it is shown that there is a role for private money.

From old to new developmentalism in Latin America

O fracasso do consenso de Washington e das políticas macroeconômicas, baseadas em altas taxas de juros e taxas de câmbio não-competitivas para promover o crescimento da economia, levou os países da América Latina a formularem estratégias nacionais de desenvolvimento. O novo desenvolvimentismo é uma estratégia alternativa não apenas à ortodoxia convencional, mas também ao antigo nacional-desenvolvimentismo latino-americano. Enquanto o antigo nacional desenvolvimentismo era baseado na tendência à deterioração dos termos de troca e, adotando uma abordagem microeconômica, propunha planejamento econômico e industrialização, o novo nacional-desenvolvimentismo pressupõe que a industrialização foi alcançada, apesar de em diferentes estágios em cada país, e argumenta que, para assegurar rápidas taxas de crescimento e o catch up, a tendência que deve ser neutralizada é a da sobrevalorização da taxa de câmbio. Contrariamente à economia convencional, um estado capaz continua sendo o instrumento chave para assegurar o desenvolvimento econômico, a política industrial continua sendo necessária; mas o que distingue a nova abordagem é principalmente o crescimento com poupança interna, ao invés de com poupança externa. Uma política macroeconômica baseada em taxas de juros moderadas e uma taxa de câmbio competitiva, e não altas taxas de juros e moeda sobreapreciada conforme recomenda a ortodoxia convencional.

Analysis of the restructuring of the Russian defence industry (by the example of aviation industry and knaapo) and the creation of United Aviation Construction Corporation

The present study is focused on the analysis of the three main governmental measures occurred in 2000-2006 in Russian defense industry: the creation of the holding structures, the establishing of the state monopoly in arms export, and creation of the United Aviation Construction Corporation (Ob¿edinennaya Aviastroitel¿naya Corporatziya), which was initiated by the President and Government of Russian Federation in 2006. The last project assumes the consolidation and joining of all producers of civil and military aviation into one united corporation in order to save the technological and productive potential of the sector after serious crisis in 1990-s. On the other hand, this project can be considered as one of the measures to establish state control and hierarchy in the defense industry. The current project tries to analyze the necessity and the possible impacts of restructuring processes. In order to perform such analysis, I need to observe the evolution of the sector, which involves the description of the restructuring and reforming of the industry since the disintegration of the Soviet Union. The current situation in aviation sector was shaped by number of reforms performed by Government of Russian Federation, which I describe in phases: conversion, privatization, decentralization, followed by evident desire of the state to establish control over some companies. Later on, I am trying to understand the reasons lying behind all reforms of 2000-2006 and the integration of the industry. I also try to predict which impacts on the companies it will have. The last part presents the main conclusions of the paper.

Integrability and the demand for monetary assets: an alternative approach to an old problem

This note provides necessary and su¢cient conditions for some speci…c multidimensional consumer’s surplus welfare measures to be well posed (path independent). We motivate the problem by investigating partial-equilibrium measures of the welfare costs of in‡ation. The results can also be used for checking path independence of alternative de…nitions of Divisia indexes of monetary services. Consumer theory classically approaches the integrability problem by considering compensated demands, homothetic preferences or quasi-linear utility functions. Here, instead, we consider demands of monetary assets generated from a shopping-time perspective. Paralleling the above mentioned procedure, of …nding special classes of utility functions that satisfy the integrability conditions, we try to infer what particular properties of the transacting technology could assure path independence of multidimensional welfare measures. We show that the integrability conditions are satis…ed if and only if the transacting technology is blockwise weakly separable. We use two examples to clarify the point.

Old-age benefits and retirement decisions of rural elderly in Brazil

I estimate the impact of social security benefits on retirement decisions of rural workers by studying changes in the roles governing social security in Brazil. I focus on a 1991 reform, which brought a reduction in the minimum eligibility age for males and females, a doubling of benefit values and the extension of benefits to non-heads of households. Because beneficiaries are not subject to means or retirement tests, I estimate apure income effect. I find that a reduction in the minimum eligibility age for old-age benefits was an important determinant in the reduction in labor supply of elderly rural workers in Brazil. Finally, I find that benefit take-up rates are larger among the better educated, but least-schooled workers show the largest labor supply responses to the reform.

Brazil’s 35 years-old quasi-stagnation: facts and theory

Brazil is growing around 1% per capita a year from 1981; this means for a country that is supposed to catch up, quasi-stagnation. Four historical new facts explain why growth was so low after the Real Plan: the reduction of public savings, and three facts that reduce private investments: the end of the unlimited supply of labor, a very high interest rate, and the 1990 dismantling of the mechanism that neutralized the Dutch disease, which represented a major competitive disadvantage for the manufacturing industry. New-developmental theory offers an explanation and two solutions for the problem, but does not underestimate the political economy problems involved
