Public deficits and economic growth

Considering an integrated area, this paper deals with the balance between the positive effects in the degree of economic cohesion resulting from R&D subsidies, temporarily granted from an imitator and less developed country, and the external negative effects arising from the eventual creation of excessive public deficits.We propose and numerically solve a model of a monetary union between two countries, one being innovator and the other imitator. Results suggest the pertinence of allowing for a temporary differentiation of fiscal discipline rules in favour of the less developed country. R&D subsidies granted by this country seem to lead to an easier catching-up without producing important negative external effects, also as not hurting severely the conditions for long-run sustainability of public accounts.     

Horizontal inequality and ethnic diversity in Brazil: patterns,trends, and their impacts on institutions

In this paper, we analyse the patterns and trends of horizontal inequality and ethnic diversity in Brazil in the past 30 years and their effect on the quality of the country’s institutions. Using data from the last four demographic censuses (1980, 1991, 2000, and 2010), we estimate numerous measures to analyse inequalities between different ‘ethnic’ groups. Our results show that, in Brazil between 1980 and 2010, the trend toward greater equality shown in other analyses of vertical inequality, is also found in terms of horizontal inequalities along racial, gender, and regional lines. Nevertheless, horizontal inequalities in terms of race and gender, in particular, remain pronounced. Ethnic diversity regarding race and religion has increased since 1980. Through our regression analysis, we note that both horizontal inequality and ethnic diversity negatively affect the institutional quality of Brazilian municipalities.     

A comparative study of bureaucratic corruption in Latin America and the U.S.A.

The starting point of this paper is a conceptual model of bureaucratic corruption, based on the assumption that bureaucrats (a) maximize personal utilities, and (b) control a monopoly in the production of certain goods and services. This conceptual model leads to a system of three equations representing demand, supply and market clearance of the goods and services supplied by the bureaucracy. Using the market clearance equation, an equation for the level of corruption in a bureaucracy is obtained. The conceptual model helps to specify the signs of the partial derivatives of the level of corruption with respect to the explanatory variables. Two sets of data are used to test the model. The first refers to levels of corruption in the bureaucracies of 17 Latin American countries, while the second deals with levels of corruption of Federal officials working in individual states in the U.S.A., state officials, and local officials. The conclusions obtained thus far using the statistical analysis confirm the expectations derived with the conceptual model.     

A down-and-out exchange option model with jumps to evaluate firms' default probabilities in Brazil

We develop a tractable structural model to estimate a firm's default probability by modeling its asset and debt behavior. The model incorporates jump factors. For a set of Brazilian large corporations, we compare the structural model results to the default probabilities predicted by a survival analysis applied to the Central Bank debt information database. Our model outperforms other structural models. In a last step, we use a firm's sector failure probabilities to calibrate the model. This process is executed by adjusting the model jump volatility and it helps to explain the differences between debt and equity market failure probabilities.     

Integrating technology roadmapping and portfolio management at the front-end of new product development

Many authors point out that the front-end of new product development (NPD) is a critical success factor in the NPD process and that numerous companies face difficulties in carrying it out appropriately. Therefore, it is important to develop new theories and proposals that support the effective implementation of this earliest phase of NPD. This paper presents a new method to support the development of front-end activities based on integrating technology roadmapping (TRM) and project portfolio management (PPM). This new method, called the ITP Method, was implemented at a small Brazilian high-tech company in the nanotechnology industry to explore the integration proposal. The case study demonstrated that the ITP Method provides a systematic procedure for the fuzzy front-end and integrates innovation perspectives into a single roadmap, which allows for a better alignment of business efforts and communication of product innovation goals. Furthermore, the results indicated that the method may also improve quality, functional integration and strategy alignment.     

Integrated economic accounting

Summary The object of the paper is to present micro and macro accounting as an integrated conceptual body, logically derived from a limited number of basic assumptions. The are applied to an economy with five micro economic units: Households, Industries, Banks, Government and Rest of the World. The basic macro economic statement -to be called the National Transactions Table - is obtained as a systematic organization and consolidation of all the micro statements. The first macro statement derived from the National Transactions Table is the Generalized Equation of Exchange. With this, Fisher's Equation of Exchange is given, first, a logical foundation, second, its correct formulation both for its aggregated and disaggregated forms, and finally, the place that naturally corresponds to it in a social accounting system. Leaving for a moment the logical derivation of the macro accounting statements, some of the properties of the Generalized Equation of Exchange are explored. In particular, the properties of the sectoral velocities of circulation are analized. Returning to the accounting aspects of the study, the Flow of Funds, Input -Output, Income and Product and Savings and Investment statements are derived from the National Transactions Table and some of their properties are explored.The author wishes to express his appreciation to Prof. G. Gruver, Department of Economics, University of Pittsburgh, and to his students Mr. and Mrs. H. Braslavsky, for their cooperation in the preparation of this paper.     

The Scenario of Lean Product Development in Brazilian Auto-industry

The purpose of this paper is to evaluate the impact of lean product development （LPD） in the Brazilian automotive sector. A mailed-questionnaire survey was used to examine 23 questions about LPD principles and practices. The target population for the study was Brazil＇s largest product development and design companies. The study identified that although the automobile sector is seen as a reference in the adoption of lean practices, there is still potential for improvement by establishing partnership relations with suppliers, and with those on the other points of the chain by identifying what provides value to clients. Set-based concurrent engineering is also a practice that needs to be better developed, as well as the value stream mapping tool to identify waste and activities that add value to the product development process. There has been no previous study of this nature in Brazil that characterizes the sector and highlights its importance in relation to the global scene, providing incentives to international investors. The value of the work is in the results that allow diagnosing the lean development practices that are most used in the automotive sector. Moreover, the survey questions can be applied in other economic sectors and at companies of other sizes. The study contributed to providing a systematic view of the product development process from the perspective of people, processes, and technology, and assists companies and academics manage change.
