title: UNEMPLOYMENT AND LABOR FORCE PARTICIPATION IN THE METROPOLITAN AREAS OF PORTO ALEGRE AND SALVADOR

description: ABSTRACT This article aims to investigate the long-term relationships between unemployment and labor force participation in the metropolitan areas of Porto Alegre and Salvador from 1997 to 2014, using Johansen’s cointegration methodology. The research was conducted with data from the Employment and Unemployment Survey - the only in the country that allows working with quarterly time series for these two metropolitan areas throughout the study period. In the metropolitan area of Salvador, both aggregated and gender-segmented data showed long-term relationships between unemployment and labor force participation rate; whereas in the metropolitan area of Porto Alegre, such a relationship was found only for the female segment. Estimates of the cointegration vectors showed a direct relationship between unemployment and labor force participation in both metropolitan areas, denoting the occurrence of the added worker effect.

title: PUBLIC EXPENDITURES AND TAX REVENUES IN BRAZIL: A PARAMETER SENSITIVITY ANALYSIS

description: ABSTRACT This article aims to measure fiscal multipliers for the Brazilian economy, considering the possible effects of economic activity shocks on central government fiscal revenues, based on a sensitivity analysis of parameters. The research was conducted with a structural vector autoregressive model with treatment of the problems of structural breakdown and identification of the structural model, which was addressed using the shock of economic activity on central government revenues as a reference for the parameter sensitivity analysis. The main results show that changes in the tax burden have important effects on the measurement of tax multipliers.

title: EXTERNAL PROTECTION, CAPITAL CONTROLS, AND DIFFERENTIATED INSERTION OF ASIAN AND LATIN AMERICAN ECONOMIES INTO THE FINANCIAL GLOBALIZATION (1995-2016)

description: ABSTRACT This paper analyses the differentiated insertion of Asian and Latin American economies into the financial globalization from 1995 to 2016, highlighting the relationship between the current account balance and the use of capital controls. It argues that, in the context of financial globalization, higher levels of external protection and the use of capital controls are fundamental to maintain the real exchange rate at a competitive level. Evidence from the six largest Latin American countries and the Asian Tigers and China (excluding Taiwan) show that countries with higher levels of external protection, that is, with high and persistent current account surpluses based on the production and export of high value-added products, were less dependent on more volatile international capital inflows and more able to use higher and more stable capital controls over time as well as to maintain the real exchange rate at a competitive level.

title: EXCHANGE RATE VOLATILITY, EXPECTATIONS, AND INFLATION: AN ANALYSIS FOR THE BRAZILIAN ECONOMY FROM 2001-2017 USING THE SVAR APPROACH

description: ABSTRACT This paper aims to empirically analyze the relationship between exchange rate volatility and inflation expectations using the structural vector autoregressive (SVAR) approach. From the Keynesian theory of pricing and inflation, it hypothesizes that exchange rate volatility, amplified by trade expansion and financial liberalization, affects inflation expectations through productions costs. In both models, the results confirm the hypothesis, for the exchange rate variation exerted certain influence on the inflation expectations and, consequently, its trajectory, especially in periods of devaluation.

title: WEALTH TAX IN BRAZIL: PROPOSALS AND SIMULATIONS

description: ABSTRACT Brazil is the only country among the 20 richest and the 20 most unequal. It has one of the largest income redistribution programs in the world, Bolsa Família, but also one of the most unjust tax burdens. Taxation and economic inequality are two of the most important issues in developing countries. In a situation of economic stagnation, the government prioritized cutting expenses as a measure of fiscal balance. This paper aims to analyze the implementation of a Wealth Tax, its feasibility and tax collection by simulation with data from tax declarations. It is shown that the Wealth Tax is feasible, has a solid revenue and could be used as an instrument of fiscal justice. It could also help with fiscal equilibrium instead of other austerity measures such as cuts in expenses of essential sectors to the economic growth and well-being of Brazil.

title: EFFECTS OF FINANCIALIZATION ON PRODUCTIVE INVESTMENT: EVIDENCE FOR BRAZILIAN NON-FINANCIAL PUBLICLY TRADED COMPANIES (2010 to 2016)

description: ABSTRACT This paper sought to investigate the impact of financialization on the productive investment of publicly traded Brazilian companies from 2010 to 2016. To do so, a dynamic panel data model was estimated by Generalized Method of Moments (GMM) using accounting and financial data from these companies. Results showed that debt, cost of capital, interest on equity and dividend payments hindered the productive investment of non-financial companies, while the operating profit affected it positively. This reveals a financialization process in Brazilian companies and that such phenomenon has a negative impact on productive investment.

title: TECHNOLOGICAL OPPORTUNITIES AND FIRMS’ DIVERSIFICATION IN CLIMATE CHANGE MITIGATION TECHNOLOGIES

description: ABSTRACT This article aims to investigate whether the diversification in climate-change mitigation technologies is affected by changes in technological opportunities at the firm level. From the constitution of a unique database of patents related to climate-change mitigation technologies, this study examines 120 technology groups worldwide and the patent portfolio of 436 firms between 1990 and 2009. The results suggest a non-linear relationship (inverse-U-shape) between the level of technological opportunity and the diversification degree of firms, arguing that the reduction of diversification at a certain point in the curve can be interpreted as a consequence of the limits imposed by the firm’s potential absorptive capacity. Similarly, large companies and those with greater capacity to accumulate knowledge show higher levels of technological diversification.

title: WHICH CHARACTERISTICS OF PRICE-FIXING AGREEMENTS ARE RELATED TO A GREATER DAMAGE TO CONSUMERS?

description: ABSTRACT Despite the deterrence effect generated by antitrust laws, the fact is that many collusive agreements end up forming in the economy. An essential task is to understand how distinct market characteristics affect cartel profits and damages. This paper develops a theoretical model to assess which characteristics of price-fixing agreements are related to greater damage to consumers. Results indicate the following characteristics as responsible for greater damage: higher product similarity (substitutability); lower elasticity of demand (in absolute values); greater number of members; higher demand potential; and a higher velocity of transactions. Price-fixing agreements that have these characteristics more intensely, in comparison to others, tend to be more harmful to consumers, and, therefore, should be prioritized by antitrust authorities regarding detection, prosecution, and punishment.

title: DLC Films Grown On Steel Using An Innovator Active Screen System For PECVD Technique

description: In this work, an active screen plasma discharge system based technology was incorporated in a PECVD reactor for DLC films growth, making it a new development in DLC films deposition. In this case, the active screen system is used to seek better electrons confinement, which might result in high ions density due to the collisions number increase, leading to a possible increase in ionization. DLC films were grown on steel substrates, using two variations of this system. In order to enhance adhesion between coating and substrate, a silicon interlayer was deposited, using different bias voltages. Morphological and structural characterization was performed by scanning electron microscopy, optical profilometry and Raman scattering spectroscopy. Tribological tests were performed by nanohardness, scratch and wear tests. Results showed that the plasma confinement promoted good films adhesion, which may be related to a high sub-implantation. This might be a consequence of the pressure decrease, as well as, to the ions energy distribution narrowing.

title: Mechanical Properties and Crystallographic Texture of Symmetrical and Asymmetrical Cold Rolled IF Steels

description: Abstract The crystallographic texture developed during cold rolling and subsequent annealing of interstitial free sheet steels aims to increase conformability. For this, it is necessary to obtain partial α-fiber and continuous and homogeneous γ-fiber texture components. In this work, the influence of symmetric (SR) and asymmetric (AR) cold rolling on crystallographic texture and mechanical properties of an interstitial free steel (IF) was investigated. Symmetric cold rolling yields α- and γ-fibers, which are enhanced as deformation increases. Moreover, α-fiber weakening occurs due to recrystallizations, improving formability. The same fibers are produced by asymmetric cold rolling, but in this case, the γ-fiber is slightly shifted in psi, which is one of Euler angles second ROE's notation1,2, and more homogeneous than in symmetric rolling. The best mechanical properties were achieved by asymmetric cold rolling/annealed with about 80% deformation.

title: AISI 1005 Steel Plasma Treated by Different Thermochemical Surface Treatments

description: Abstract To modify the surface structure of AISI 1005 steel and its properties without any dimensional loss, different plasma surface treatments were performed at low temperatures (500 ºC) in this study. The samples were subjected to single plasma treatments including: nitriding (N5% and N3%), carburizing (CE) and ferritic nitrocarburizing (NC) and to duplex treatments of nitriding followed by carburizing (N5%+CE and N3%+CE) and ferritic nitrocarburizing followed by carburizing (NC+CE). The gas mixture used for these treatments was varied as follows: nitriding (5%N2+95%H2 and 3%N2+97%H2), carburizing (5%CH4+95%H2) and ferritic nitrocarburizing (5%N2+1.5%CH4+93.5%H2). A microstructural characterization of the samples was carried out using optical and scanning electron microscopy in addition to XRD analysis. Microhardness testing was also performed. The XRD analysis showed a stabilization of the outermost cementite layer for all of the carburizing treatments. The results show that a greater hardness increase was achieved for the nitriding treatment as well as a more regular compound layer. However, a greater depth of hardening was obtained in samples with NC+CE and N5%+CE, which extended to the hardened depth to 800 µm.
