A structural economic dynamics approach to balance-of-payments-constrained growth

This paper derives a balance-of-payments equilibrium growthrate analogous to Thirlwall's Law from a Pasinettian multi-sectormacrodynamic framework. The resulting formula, which we callthe Multi-Sectoral Thirlwall's Law, asserts that a country'sgrowth rate of per capita income is directly proportional tothe growth rate of its exports, with such a proportionalitybeing inversely (directly) related to sectoral income elasticitiesof demand for imports (exports). These income elasticities areweighted by coefficients that measure the share of each sectorin total imports and exports, respectively. It is shown thatseveral theoretical, empirical and policy implications can bedrawn from such a structural economic dynamics approach to balance-of-payments-constrainedgrowth.     

The Cost Channel of Monetary Transmission and Stabilization Policy in a Post-Keynesian Macrodynamic Model

This paper develops a macrodynamic model that takes into account the potentially inflationary consequences of interest rate manipulations through the cost channel of monetary transmission. Evaluations of the macroeconomic implications of the cost channel are common in the mainstream literature. But this literature uses supply-determined macro models and provides standard optimizing microfoundations for the various ways in which the interest rate can affect mark-ups, prices and ultimately the form of the Phillips curve. Our purpose is to study the implications of different Phillips curves, each embodying the cost channel and derived from Post-Keynesian, cost-based-pricing microfoundations, in a monetary-production economy. We focus on the impact of these Phillips curves on macroeconomic stability and the consequent efficacy of stabilization policy. Ultimately, our results suggest that the presence of the cost channel is less significant for stabilization policy than the general orientation of the policy regime. These results corroborate earlier findings that, in a monetary-production economy, more orthodox policy regimes are inimical to macro stabilization.     

Repurchase intent antecedents of a competitive brand in the smartphones segment

This research has analyzed the influence of perceived value, affective commitment, normative commitment and positive word of mouth as antecedents of repurchase intention of smartphones of a particular brand. The analysis of the results was made by means of multivariate statistics, applying Structural Equation Modeling technique. The sample consisted of 283 valid cases. The results showed that perceived value positively influences the affective commitment and normative commitment; perceived value by customers does not positively influences positive word of mouth; affective commitment positively influences positive word of mouth; affective commitment positively influences repurchase intention; normative commitment positively influences repurchase intention; and positive word of mouth positively influences repurchase intention of a product of the same brand.     

Systems of innovation and innovation ecosystems: a literature review in search of complementarities

This paper aims to clarify to what extent the emerging theory of innovation ecosystems (IE) and the theory of systems of innovation (SI) are complementary and then identify how its communities could benefit from cross-fertilization. We performed a critical literature review of both topics using meta-synthesis as method to identify, analyze and compare the two theories. Using a framework, this paper explores the elements belonging to each theory’s domain, in order to identify the key factors necessary to compare the two theories. The results of this analysis show that both theories involve the assessment of three key aspects: the understanding of innovation activities, the role of the agents involved, and the interaction and resulting networks among them. A similarity was found showing that these two different theories are applications of System Thinking approach. Another finding, which has not been mentioned in previous research on the topic, is that the construction of the initial concepts of the IE theory was originally rooted in several SI elements. Finally, we found key factors that may be the cross-fertilization link between the two communities that represent each theory.     

Measuring convergence of National Accounting Standards with International Financial Reporting Standards

This paper analyses three methods for measuring the success achieved in effecting convergence between any two sets of accounting standards. We begin by reviewing a measurement method based on the concept of Euclidean distances. We then propose two better measures (involving Jaccard's coefficients and Spearman's coefficients) to assess the progress of National Accounting Standards setting bodies in converging their standards with International Financial Reporting Standards [IFRS]. For illustrative purposes, we measure the convergence of National Accounting Standards in Portugal with International Accounting Standards [IAS] and IFRS over the period 1977–2003.     

Corporate Social Responsibility and Resource-Based Perspectives

Firms engage in corporate social responsibility (CSR) because they consider that some kind of competitive advantage accrues to them. We contend that resource-based perspectives (RBP) are useful to understand why firms engage in CSR activities and disclosure. From a resource-based perspective CSR is seen as providing internal or external benefits, or both. Investments in socially responsible activities may have internal benefits by helping a firm to develop new resources and capabilities which are related namely to know-how and corporate culture. In effect, investing in social responsibility activities and disclosure has important consequences on the creation or depletion of fundamental intangible resources, namely those associated with employees. The external benefits of CSR are related to its effect on corporate reputation. Corporate reputation can be understood as a fundamental intangible resource which can be created or depleted as a consequence of the decisions to engage or not in social responsibility activities and disclosure. Firms with good social responsibility reputation may improve relations with external actors. They may also attract better employees or increase current employees’ motivation, morale, commitment and loyalty to the firm. This article contributes to the understanding of why CSR may be seen as having strategic value for firms and how RBP can be used in such endeavour.

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.
