An overview of some historical Brazilian macroeconomic series and some open questions

This paper presents an overview of the Brazilian macroeconomy by analyzing the evolution of some specific time series. The presentation is made through a sequence of graphs. Several remarkable historical points and open questions come up in the data. These include, among others, the drop in output growth as of 1980, the clear shift from investments to government current expenditures which started in the beginning of the 80s, the notable way how money, prices and exchange rate correlate in an environment of permanently high inHation, the historical coexistence of high rates of growth and high rates of inHation, as well as the drastic increase of the velocity of circulation of money between the 70s and the mid-90s. It is also shown that, although net external liabilities have increased substantially in current dollars after the Real Plan, its ratio with respect to exports in 2004 is practically the same as the one existing in 1986; and that residents in Brazil, in average, owed two more months of their final income (GNP) to abroad between 1995-2004 than they did between 1990 and 1994. Variance decompositions show that money has been important to explain prices, but not output (GDP).

A monthly indicator of Brazilian GDP. The Brazilian business cycle and growth cycle

This paper constructs an indicator of Brazilian GDP at the monthly ftequency. The peculiar instability and abrupt changes of regimes in the dynamic behavior of the Brazilian business cycle were explicitly modeled within nonlinear ftameworks. In particular, a Markov switching dynarnic factor model was used to combine several macroeconomic variables that display simultaneous comovements with aggregate economic activity. The model generates as output a monthly indicator of the Brazilian GDP and real time probabilities of the current phase of the Brazilian business cycle. The monthly indicator shows a remarkable historical conformity with cyclical movements of GDP. In addition, the estimated filtered probabilities predict ali recessions in sample and out-of-sample. The ability of the indicator in linear forecasting growth rates of GDP is also examined. The estimated indicator displays a better in-sample and out-of-sample predictive performance in forecasting growth rates of real GDP, compared to a linear autoregressive model for GDP. These results suggest that the estimated monthly indicator can be used to forecast GDP and to monitor the state of the Brazilian economy in real time.

Informal labor contracts: an analysis of the Brazilian experience

For representing an expressive souree of labor absorption, the jobs with informal labor eontraet have been reeeiving a eonsiderable attention among the speeialists in the Brazilian labor rnarket. This paper presents, eoneisely, some stylized faets about this labor rnarket segment, as well as some oftheir most eommon interpretations. We argue that sue h interpretations are, in general, not very integrated and a model trying to make them eompatible is developed. The model ineorporates both segmentation and workers with heterogeneity in qualifieation. The results of the analysis are shown to be eompatible with most of the observed faets.

Quality change in Brazilian automobiles

In this paper I investigate the quality evolution ofBrazilian autos. To measure the quality evolution of Brazilian autos, I have assembled a data set for Brazilian passenger cars for the period 1960-1994, to which I have applied the hedonic pricing methodology. To the best of my k:nowledge, this is the first time an index of quality change has been constructed for the Brazilian automobile industry. The results presented here have two major implications. They allow a better -- ......... understanding of product innovation in Brazil's auto industry, and they provide a clearer explanation of the behavior of auto prices.

Capital flows and monetary control under a domestic currency substitution regime: the recent Brazilian experience

The 90s have witnessed a resumption in capital flows to Latin America. due to the conjugation of low interest rates in the US and economic reforms in most LA countries. In Brazil. however. substantial capital flows have becn induced by the extremely high domestic interest rates practiced by the Central Bank as a measure of last reson given the absence of successful stabilization policies. These very high interest rates were needed to prevent capital flight in a context of a surprisingly stable inflation rate above 20% a month. and keep interest bearing govemment securities preferable to foreign assets as money substitutes. We carefully describe how this domestic currency substitution regime (interest bearing govemment securities are substituted for MIas cash holdings) requires the Central Bank to renounce aoy control over monerary aggregates. In this domestic currency substitution regime. hyperinflation is the most likely outcome of an isolated (i.e.. without fiscal adjusanents) attempt by the Brazilian Central Bank to control money.

Pricing the option adjust spread of Brazilian Eurobonds

This paper presents results of a pricing system to compute the option adjusted spread ("DAS") of Eurobonds issued by Brazilian firms. The system computes the "DAS" over US treasury rates taktng imo account the embedded options present on these bonds. These options can be calls ("callable bond"), puts ("putable bond") or combinations ("callable and putable bond"). The pricing model takes into account the evolution of the term structure along time, is compatible with the observable market term structure and is able to compute risk measures such as duration and convexity, and pricing and hedging of options on these bonds. Examples show the ejJects of the embedded options on the spread and risk measures as well as the ejJects on the spread due to variations on the volatility parameters ofthe short rate.

Avoiding some costs of inflation and crawling toward hyperinflation : the case of the Brazilian domestic currency substitute

The pattem of a classical hyperinflation is an acute acceleration of the inflation levei accompanied by rapid substitution away from domestic currency. Brazil, however, has becn experiencing inflation leveis well above 1,000% a year since 1988 without entering the classical hyperinflation path. Two elements play key roles in differcntiating the Brazilian case from other hyperinflationary experiences: indexation and the provision of a reliable domestic currency substitute, Le., the provision of liquidity to interest-bearing assets. This paper claims that the existence of this domestic currency substitute is lhe main source of both lhe inability of the Brazilian central bank to fight inflation and of the unwillingness of Brazilians to face the costs of such a fight. The provision of the domestic currency substitute through the banking sector is modeled, and the main macroeconomic consequences of this monetary regime are derived. Those are: the lack of a nominal anchor for the price system due to the passive monetary policy; the endogeneity of seignorage unlikc traditional models of hyperinflation; and lhe ineffectiveness of very high real interest rates.

Ownership, control and corporate valuation of Brazilian companies

We study the direct and indirect ownership structure of Brazilian corporations and their market value and risk by the end of 1996 and 1998. Ownership is quite concentrated with most companies being controlled by a single direct shareholder. We find evidence that indirect control structures may be used to concentrate control even more rather than to keep control of the company with a smaller share of total capital. The greater the concentration of voting rights then less the value of the fmn should be due to potential expropriation ofrninority shareholders. We fmd evidence that when there is a majority shareholder and when indirect ownership structures are used without the loss of control, corporate valuations are greater when control is dilluted through the indirect ownership structure. This evidence is consistent with the existence of private benefits of control that can be translated as potential minority shareholder expropriation.

Os efeitos da redução da jornada de trabalho de 48 para 44 horas semanais sobre o mercado de trabalho no Brasil

The reduction of standard weekly working hours from the curreilt leveI of 44 hours to 40 hours has recently been proposed by the main central unions as a way to create jobs and reduce unemployment in Brazil. The idea, known as work-sharing, is that the reduction in average hours per worker allows the same tasks to be performed bymore employees. However, the notion ofwork-sharing has been challenged by the theoretical and the empirical literature. Theory says that, in general, a reduction in the duration ofthe workweek tends to decrease employment. Work-sharing is even less likely in the case of no wage restraint, when monthly wages are not proportionally reduced. Recent cautious econometric evidence also conflict with the notion of work -sharing (Hunt, 1999, and Crépon and Kramarz, 2000). The objective ofthis paper is to study the effects ofthe workweek length reduction from 48 to 44 hours, prescribed by the 1988 Constitutional change, on the Brazilian labor market. We find that: i) the reduction of standard working hours was followed by a significant decrease in actual working hours: 60,7% ofthe employees that worked between 45 and 48 weekly hours in 1988 (the affected group) and that remained employed in 1989 switched to a 40-44 hours workweek; ii) belonging to the affected group in 1988 had no statistical effect on the probability ofbecoming unemployed, exiting the labor market, or switching to an informal job in 1989; iii) the reduction in working hours implied a 8,8% increase in hourly real wages with respect to those that remained employed at 40-44 hours a week. In sum, the reduction of standard working hours in 1988 reduced actual working hours, did not affect the probability ofa typical worker to lose hisjob in 1989, and implied a relative increase in hourly real wages.

Brazilian privatization : a decade of experience

In this paper we review the ten-year-old Brazilian experience with privatization. We start by describing the expansion in the last half century of the role played by state enterprises, and then the privatization effort in the Figueiredo and Sarney administrations. After that, we examine what haa changed with Collor and what the prospects for his privatization program are.

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.

Inferring conduct under the threat of entry : the case of Brazilian cement industry

This paper demonstrates that when an industry faces potential entry and this threat of entry constrains pre-entry prices, cost and conduct are not identified from the comparative statics of equilibrium. In such a setting, the identifying assumption behind the well-established technique of relying on exogenous demand perturbations to empirically distinguish between alternative hypotheses of conduct is shown to fail. The Brazilian cement industry, where the threat of imports restrains market outcomes, provides an empirical illustration. In particular, pricecost margins estimated using this established technique are considerably biased downward, underestimating the degree of market power. A test of conduct is proposed, adapted to this constrained setting, which suggests that outcomes in the industry are collusive and characterised by market division.

Economic landscapes, what are they? an application to the Brazilian economy and to the sugar cane complex

In assessing the economic impact of a sector or group of sectors on a single or multiregional economy, input-output analysis has proven to be a popular method. . However, there has a problem in displaying all the information that can be obtained from this analytical approach. In this paper, we have tried to set new directions in the use of input-output analysis by presenting an improved way of looking at the economic landscapes. While this is not a new concept, a new meaning is explored in this paper; essentially, it will now be possible to visualize, in a simple picture, all the relations in the economy as well as being able to view how one sector is related to the other sectors/regions in the economy. These relations can be measured in terms of structural changes, production, value added, employment, imports, etc. While all the possibilities cannot be explored in this paper, the basic idea is given here and the smart reader can uncover all the various possibilities. To illustrate the power of analysis provided by the economic landscapes, an application is made to the sugar cane complex using an interregional inputoutput system for the Brazilian economy, constructed for 2 regions (Northeast and Rest of Brazil), for the years of 1985, 1992, and 1995.
