title: FERNANDO CARDIM DE CARVALHO, FINANCIAL SYSTEMS, AND THE FINANCING OF CAPITAL ACCUMULATION

description: ABSTRACT This paper revisits the contributions of Professor Fernando Cardim de Carvalho on the theme of the financing of capital accumulation in monetary economies. It highlights two functions that ideally should be fulfilled by the financial sector to allow market economies to sustain growth and avoid financial instability. The first one relates to ensuring the additional supply of liquidity created by hikes in production and investment (finance motive). The second refers to the provision of mechanisms to fund long-term undertakings, therefore softening the tendency to financial fragility (funding) along the process. The article builds on the foundations put forth by Cardim to suggest that private financial institutions often fail to fulfill these functions due to informational problems and uncertainty, especially in the phase of structural transformation. It concludes by advocating the need for public policies to develop financial markets and instruments that are appropriate to support economic development, which involves transformational investments.

title: WAGE FLEXIBILITY, EXCHANGE-RATE COMPETITIVENESS AND FULL EMPLOYMENT: THE FIRST HERETICS

description: ABSTRACT This paper discusses Keynes’ and Kalecki’s rejection of the notion that downward wage flexibility would ensure full employment, recollecting also Steindl’s stagnation theory, which extends to the long-run Kalecki’s ideas. It then considers the association between wage fall and currency depreciation and examines the Latin American contribution to the arguments of why currency devaluation may depress aggregate demand. Afterwards, it briefly reflects on the economic policy consequences that the authors studied here inferred from their analysis. It finally adds a succinct remark on the author’s empirical findings on this issue.

title: GLOBAL VALUE CHAINS, INNOVATION AND UPGRADING: A MICRODATA BASED STUDY OF ARGENTINIAN INDUSTRIAL FIRMS

description: ABSTRACT The debate on global value chains (GVC) has gained momentum recently, especially concerning the advantages and drawbacks for the countries that enter their orbit. Inspired by this discussion, this article examines the insertion of Argentine industrial firms in GVC using microdata from the Encuesta Nacional de Dinámica de Empleo e Innovación (ENDEI). The text begins with a discussion on the relations involving GVC, productive stages of the participating countries and the issue of innovation, and then looks at the Argentine manufacturing sector as allowed by the database. The results confirm, for Argentina, the postulations brought by the literature on the involvement profile of middle-income economies in CGV. Among the Argentine firms comprised in this database, some export dynamism has been observed in high and medium / high technology sectors, but an insertion based on assembly and processing, with limited technological endogenization, has prevailed.

title: DRIVERS OF SCIENTIFIC-TECHNOLOGICAL PRODUCTION IN BRAZILIAN HIGHER EDUCATION AND RESEARCH INSTITUTIONS

description: ABSTRACT This article estimates a knowledge production function for Brazilian universities, relating their inputs of scientific activity, such as the total of academic and administrative personnel and investments in scientific research, among others, to their outputs, such as the number of publications and patents. The article applies econometric models for count data, such as the Negative Binomial, for the 2003-2011 period. The overall results show that the main determinants of Brazilian scientific and technological production are the size of the university, its nature (whether public or private), the ratio of teaching staff and graduate students, and total investments in research and research support.

title: THE INFLUENCE OF FINANCIALIZATION ON THE BRAZILIAN REAL INTEREST RATE

description: ABSTRACT This paper analyzes the real interest rate in Brazil. First, we define financialization as the major influence of the financial system on domestic politics. We use the proportion of the stock of federal public debt held by financial market agents as a proxy for financialization. Subsequently, we adopted the VEC methodology to perform cointegration and impulse-response analyses for the period 2007-2017. The results suggest that financialization had a positive effect on the real interest rate level.

title: OLIGOPSONY AND BUYER POWER IN THE BRAZILIAN FOOD RETAIL: THE DAIRY PRODUCTS CASE

description: ABSTRACT The recent concentration in the Brazilian food retail market facilitates buyer power on the purchase of products. The situation is more acute in the dairy sector due to recent innovations and reorganization in the production chain. This paper aims to verify whether the retail industry wields buyer power on the purchase of dairy products in the metropolitan region of São Paulo. The theoretical model provides a test to analyze if retail prices are detached from raw material prices, which is a good indicator of retailers’ buyer power. The results show evidence of buyer power on the purchase of the three types of products, namely, UHT fluid milk, type B fluid milk, and type C fluid milk. It raises important discussions regarding the dairy industry behavior and the public enforcement of mergers and acquisitions.

title: Characterization of the complete plastid genome of Butia eriospatha (Arecaceae)

description: Abstract Butia eriospatha is an endemic palm species from the Atlantic Rainforest in Brazil, a biodiversity hotspot. This species is currently listed in the IUCN red list as vulnerable and lacks specific plastid markers for population genetics studies. In addition, the evolutionary relationship within the genus Butia is not yet well resolved. Here, we sequenced and characterized the complete plastid genome (plastome) sequence of B. eriospatha. The complete plastome sequence is 154,048 bp in length, with the typical quadripartite structure. This plastome length and genes content is consistent with other six species from tribe Cocoseae. However, the Inverted Repeat (IR) borders show some variation among the analyzed species from this tribe. Species from the Bactridinae (Astrocaryum and Acrocomia) and Elaeidinae (Elaeis) subtribes present the rps19 gene completely duplicated in the IR region. In contrast, all plastomes sequenced from the subtribe Attaleinae (Butia, Cocos, Syagrus) present one complete CDS of rps19 and one partial copy of rps19. The difference in the IR/LSC junctions between Attaleinae and the sister clades Bactridinae + Elaeidinae might be considered an evolutionary signal and the plastome sequence of B. eriopatha may be used in future studies of population genetics and phylogeny.

title: ANOTHER LOOK AT THE FINANCING OF SOCIAL SECURITY IN BRAZIL: THE KEY ROLE OF FORMALIZING WORK, INCREASING PRODUCTIVITY AND ENHANCING REVENUE MANAGEMENT

description: ABSTRACT This article analyzes a set of variables deemed relevant for the financing of social security in Brazil, which have been overlooked in the recent debate on the subject. At first, we introduce a theoretical model that highlights the key role of increasing productivity, expanding formal employment, and enhancing revenue efficiency in the financing of social security. We then analyze the trajectory of these variables in Brazil and suggest measures to stimulate them. Finally, we perform a simulation exercise to test the effects of changes in the selected variables on the outcomes of social security. The results indicate that in face of positive shocks in labor productivity, formal employment, and pension income, the General Social Security System (RGPS) results become a surplus. A key implication of this result is that problems in the financing of social security cannot be solved exclusively by cutting benefits.

title: Thermomechanical simulation of prisms with concrete blocks in a fire situation

description: ABSTRACT Fires in buildings are frequent in the world. Concrete blockwork masonry is a constructive system widely used in Brazil and poorly studied in a fire situation. At room temperature, the axial compressive strength of the masonry can be estimated by axial compression of prisms. In addition, by means of prisms, it is possible to represent the loss of mechanical resistance due to thermal deterioration. Thus, the purpose of the current study is to verify, in purely numeric context, the mechanical resistance of prisms with concrete blocks under compression in a fire situation, through thermomechanical simulation. Initially, the compression of the prism was simulated at room temperature with the objective of validate the materials’ properties. Posteriorly, it was adopted in the study properties based on the technical literature, at high temperatures. The boundary conditions were varied, two levels of loading were applied and cases of prism with one and two faces exposed to fire were verified. In the simulations, the application of a higher loading level, the vertical displacement restriction and the double-sided fire exposure anticipated the prism failure. The lack of rotational restraint generated a mode of rupture different from the case with rotational restraint and in less time of fire. The use of properties found in the technical literature led to a time of mechanical resistance favorable to safety.

title: Effect of water content and particle size on the thermal decomposition of ground cement paste

description: ABSTRACT A possible method for producing eco-efficient concrete would be the partial replacement of Portland cement by pastes and mortars residues subjected to thermal-mechanic treatment. In this context, this study evaluates the influence of water/cement (w/c) ratio and average particle size on the thermal decomposition of hydrated cement. Cement pastes with three w/c ratios (0.40, 0.50 and 0.60) and cured by 28 days were ground to obtain two particle distributions with average sizes of 0.60 mm and 0.15 mm. The thermal decomposition of pastes was analysed by thermal gravimetric analysis (TGA), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). TGA analysis indicates that chemically bounded water content is improved by the increasing of w/c ratio between 0.40 and 0.50, but it is constant between w/c of 0.50 and 0.60. Particle size reduction almost does not interfere with TGA curves. According to XRD e TGA analysis, most hydrates are decomposed at 500-550 °C, while calcium silicates and calcium aluminates similar to the anhydrous phases of Portland cement were detected on the heated paste at 750 °C. Thus, higher temperatures would be required for the complete recovery of the anhydrous cement in hydrated pastes.

title: Evaluation of coal ash use as an adhesion improver in asphalt mixtures

description: ABSTRACT The presence of moisture in asphalt mixtures interferes in the adhesion between the asphalt binder and the aggregates, as well as interferes into the asphalt binder film itself causing cohesive failure. This work evaluated the use of coal ashes as a bonding improver in asphalt mixtures, comparing this material with hydrated lime and stone powder. A total of 36 ash samples were collected at the UTE Energia Pecém/São Gonçalo do Amarante-CE, and a chemical characterization was performed using the X-ray fluorescence. It was found that about 68% of the ashes belong to class C, the remainder of the ashes being framed in class F. In the evaluation of the moisture damage resistance, through the Lottman test, it was verified that the use of 4 % of ash in the asphalt mixtures generated results similar to those found for the asphalt mixture containing natural filler. The use of the ashes combined with lime led to an increase in resistance to moisture damage. It is emphasized that the fact that some ashes belong to class C or F, or even that some ashes are more alkaline than others, did not necessarily lead to significant gains in the moisture damage resistance.
