Foucault on the Marginal Revolution in Economics: Language and the Cartesian Legacy

Scholars have long debated the ‘revolutionary’ character of the ‘Marginal Revolution’ in economics, focusing on theoretical foundations, methodological devices, social context and political aspects. This article offers a new perspective by investigating ontological and epistemological conditions of that intellectual movement. This requires, in turn, a characterization of those conditions, for which purpose we will draw on Foucault's configurations of thought into ‘epistemes’ in The Order of Things. Although not mentioning those conditions, there have been few references in economics to Foucault's approach. They have mainly claimed that he neglected its importance because he did not see it as a ‘revolution’ in The Order of Things. It is argued here that he actually considered it a ‘revolution’ in The Archaeology of Knowledge. A revision of Foucault's account provides some ideas regarding deep philosophical conditions of the emergence of neoclassical theory and defies some usual interpretations of the circumstances that led to the mathematization of economics. The main conclusion is that its revolutionary character did not stem from a change of ontological beliefs, but—just as many historians of economics have defended—it was a methodological revolution. This study suggests a reinterpretation of that event, claiming that it resulted from a new conception of language and a crisis of Descartes's project of a mathematical unifying science. Going beyond that debate, these reflections proffer ideas that deserve an appraisal in economics.     

Combining monetary policy and prudential regulation: an agent-based modeling approach

This paper explores the interaction between monetary policy and prudential regulation in an agent-based modeling framework. Firms borrow funds from the banking system in an economy regulated by a central bank. The central bank carries out monetary policy, by setting the interest rate, and prudential regulation, by establishing the banking capital requirement. Different combinations of interest rate rule and capital requirement rule are evaluated with respect to both macroeconomic and financial stability. Several relevant policy implications were drawn. First, the efficacy of a given capital requirement rule or interest rate rule depends on the specification of the rule of the other type it is combined with. More precisely, less aggressive interest rate rules perform better when the range of variation of the capital requirement is narrower. Second, interest rate smoothing is more effective than the other interest rate rules assessed, as it outperforms those other rules with respect to financial stability and macroeconomic stability. Third, there is no tradeoff between financial and macroeconomic stability associated with a variation of either the capital requirement or the smoothing interest rate parameter. Finally, our results reinforce the cautionary finding of other studies regarding how output can be ravaged by a low inflation targeting.

     

Effects of the Adoption of IFRS on the Credit Market: Evidence from Brazil

Based on a sample of approximately 6500 credit ratings and 137,000 loan contracts, this paper analyzes the effects of mandatory IFRS adoption on the Brazilian credit market. We find that the IFRS adoption effects were limited to firms displaying improved accounting information quality at the time of transition, lending support to the notion that economic benefits do not necessarily flow from the publication of financial reports in IFRS but, rather, depend on how earnestly firms adopt the recommended disclosure practices.     

Crypto-assets portfolio optimization under the omega measure

Abstract

Crypto-currencies, or crypto-assets, represent a new class of investment assets. The traditional portfolio analysis approach of Markowitz is not appropriate for use with portfolios containing crypto-assets, as the model requires that the investor have a quadratic utility function or that the returns be normally distributed, which isn’t the case for crypto-assets. We develop a portfolio optimization model based on the Omega measure which is more comprehensive than the Markowitz model, and apply this to four crypto-asset investment portfolios by means of a numerical application. The results indicate that these portfolios should favor traditional market assets over crypto-assets. In the case of portfolios formed only by crypto-assets, there is no clear preference in favor of any crypto-asset in particular.     

What about sustainability? Understanding consumers' conceptual representations through free word association

The United Nations (UN) conceptualizes sustainability as development that meets the current needs of the planet's populations, but without compromising the ability of future generations to meet their own needs. Although the concept of sustainability has been widely discussed in the international political agendas, inconsistent interpretation and ambiguity of the concept by consumers is observed. In this paper, the understanding of the term sustainability amongst Brazilian consumers is reported. Using the word association projective technique, the participants were asked to write down all the words that came to their mind when thinking about “sustainability.” Thematic content analysis was performed by grouping words by similarity of meaning in categories, which were further submitted to correspondence analysis (CA) to create a perceptual map. Brazilian consumers made different associations reflecting the complexity and multidimensionality of the concept amongst different groups of consumers. The most frequently cited categories are related to environment, health and nutrition, behaviour, production and economy and sustenance. CA accounted for 76.7% of the data variance and the perceptual map evidenced that younger individuals with higher education made associations with categories related to the current concept of sustainable development, similar to that proposed by UN. Moreover, consumers with basic education were associated with categories related to food and sustenance. The findings of this study can contribute to the formulation of education strategies directed towards different social groups, besides directing further research on consumer behaviour.     

Expenditure-Based Segmentation of a Mountain Destination Tourist Market

Although tourism is one of the most dynamic economic activities worldwide, few studies have been conducted on the potential role of market segmentation based on visitors' expenditure level at the destination in order to define strategies for maximizing the economic benefits of tourism for local destinations. This study extends the research undertaken in this area by identifying different clusters of visitors, in a Portuguese mountain destination, according to the level and patterns of visitors' expenditure during the visit. Four distinct segments were identified and show statistically significant differences regarding their economic relevance for the destination, sociodemographic profile, and trip behavior. This study contributes to the discussion of analytical marketing tools available in the context of destination planning, aiming at the definition of strategies that may maximize the economic contribution of tourism for local economic development.     

Market share instability in Brazilian industry: a dynamic panel data analysis

The paper investigates market share instability in the context of Brazilian industry for the 1986–1998 period. The paper proposes the use of panel data unit root tests to access market share instability for a sample of industrial firms from different sectors and therefore generalizes related time series unit root tests proposed by Gallet and List (2001 Gallet, CA and List, JA. 2001. Market share instability: an application of unit root tests for the cigarette industry. Journal of Economics and Business, 53: 473–80.  ). The results mostly indicate that one cannot reject the hypothesis of market share instability and therefore there exist some degree of market rivalry in the Brazilian case.     

Macroeconomic Determinants of Investment under Inflation Targeting: Empirical Evidence from the Brazilian Economy

The use of interest rate as the main tool by which central banks implement inflation targets points to a strong link between private investment decisions and monetary policy. With the objective of contributing to the literature surrounding macroeconomic determinants of investment under inflation targeting, an empirical analysis through Generalized Method of Moments models for the Brazilian case is made. In a general way, the findings underscore the relevance of macroeconomic variables for the determination of investment. In particular, we find that success inflation targeting creates a stable macroeconomic environment that promotes private investment.     

Analysis of Competences for Innovation in Technology-Based Enterprise Incubators

ABSTRACT

Incubators are rated as public policy mechanisms driving innovation in companies. The purpose of this project was to ascertain the level of development of competences for innovation in Technology-Based Enterprise Incubators (TBEI) as perceived by businesspeople in associated companies. With regard to technological innovation, it was decided to use a neo-Schumpeterian approach, and with regard to competences, the Resource-Based View (RBV) theory was used, which evaluates internal attributes that contribute directly to the innovative capacity. Four constructs were taken into consideration for analyzing the development levels of competences for innovation, grounded on the model of François and colleagues (1999 François , J. P. , Goux , D. , Guellec , D. , Kabla , I. , and Temple , P. ( 1999 ). “Décrire lês Compétences pour l'innovation: une Proposition d'enquête.” In: Foray , D. , and Mairesse , J. (Eds.), Innovation et Performance, Approaches Interdisciplinaires , Editions EHESS . [Google Scholar]) and Munier (1999 Munier , F. Taille de ( 1999 ). La Firme et Innovation: Appoches Theóriques et Empiriques Fondées sur le Concept de Compétence , Thèse (Doctorat en Économie)—Estrasburgo: Université Louis Pasteur . [Google Scholar]). Competences for innovation were examined through a questionnaire that tries to identify and assess development levels of competences in TBEI. The findings were analyzed through construct reliability tests: summated scales and cluster analysis. It was noted that the means competences representing the basic resources needed for the development of the company were assessed favorably by the businesspeople, indicating the development of this competence. In terms of technical and relational competences, it was noted that the businesspeople assessed these aspects unfavorably, indicating that these competences are not well developed by the TBEI. It was also ascertained that corporate development levels and operating sectors also influence the assessment of these businesspeople in terms of competences for innovation. This leads to the conclusion that its effectiveness must be assessed as an agent of innovation, with indicators being defined to measure the effectiveness of its role as a mechanism driving technological innovation.
