Purchasing power parity in Brazil: a test for fractional cointegration

The purpose of this paper is to test the validity of the purchasing power parity (PPP) doctrine in Brazil. Historical data for the period 1855–1996 are considered. The period 1855–1990 is also analysed in order to compare the results with those obtained by Zini and Cati (1993) using the conventional cointegration analysis. This article uses fractional cointegration analysis, a flexible methodology which allows for more subtle forms of mean reversion. The tests performed are those of Geweke and Porter-Hudak (1983), and of Hurvich and Ray (1995). The critical values for both tests are generated by simulation because they are non-standard. The empirical results do not support the absolute PPP hypothesis but the relative PPP holds in the long run.     

Technology transfer in the supply chain oriented to industry 4.0: a literature review

In the supply chain oriented to Industrial 4.0 Scenario the scarcity of studies on Technology Transfer (TT) can be easily observed. TT is a fundamental process, because it steers the absorption and dissemination of technologies towards the various stages of supply chain. The objective of this study is to contextualise TT in the supply chain of Industrial 4.0 Scenario, focusing on the supply, manufacturing industry and final consumer stages. A review of the literature was carried out, using a structured protocol and criteria to compose the bibliographic portfolio. To support the questions presented in this study, the most relevant articles related to the researched topic were thoroughly analyzed. The results infers that in the Industrial 4.0 Scenario, the supply chain will go through changes, such as real-time visibility throughout the entirety of the supply chain, continuous collaboration between the stages of the chain, among other significant changes.     

New Product Development Processes and New Product Profitability: Exploring the Mediating Role of Speed to Market and Product Quality

In new product development, faster is not always better. Conceptually, being faster to market should improve financial performance by improving product quality and reducing development expenses. Empirical support is mixed, however, demonstrating that higher speed to market exhibits an inverted U‐shaped relationship with product profitability. Conventional wisdom and empirical research suggest managers make speed to market–product quality–development expense trade‐offs. A particular concern regarding speed to market is that extreme speed may jeopardize product quality. Some researchers suggest that speed to market improves product quality while others suggest firms must balance both speed to market and product quality. Also, shorter lead times may be associated with reduced development expenses, but empirical evidence is conflicting. This research attempts to reconcile conflicting results regarding the speed to market–product quality relationship, their joint impact on product profitability, and their mediation role in the effects of development expenses and cross‐functional integration on product profitability. Partial least squares (PLS) is used to analyze multiplexed archival and survey data collected from NPD managers for 1115 different NPD projects in several firms. The results support the hypothesized equations, explaining 27% of speed to market variance, 35% of product quality variance, and 45% of product profitability variance. This study makes two contributions. First, because speed to market and product quality are related, simultaneous consideration of both factors enhances insight into their joint effect. Second, it provides evidence that speed to market and product quality jointly mediate development expense by NPD phase and cross‐functional integration effects on product profitability. Key results from the large sample data analysis include the following. Speed to market and product quality both enhance product profitability, but the impact of speed to market is larger than that of product quality. Speed to market and product quality partially mediate the impact of fuzzy front end phase expenses on product profitability, while expenses in the latter phases exhibit no impact on the mediators or profitability. Thus, the results suggest that trade‐offs are made not only between time, quality, and expense (i.e., if additional expenses are incurred at all), but also that trade‐offs relate to when (i.e., in which NPD phase) additional development expenses are incurred. Finally, cross‐functional integration (both internal and external) substantially impacts product profitability through a mix of direct and mediated effects.     

Ideology and the Balanced Scorecard: An Empirical Exploration of the Tension Between Shareholder Value Maximization and Corporate Social Responsibility

In a society where the ideology of shareholder value maximization (SVM) prevails, how do evaluators make appraisal and bonus decisions when corporate social responsibility (CSR) measures and financial measures in the balanced scorecard (BSC) point in different directions? To explore this question, we conducted two studies to develop and test a conceptual framework. Participants were asked to evaluate the performance of two managers, using a case we wrote about a commercial bank. We found that (1) evaluators are more willing to drop CSR performance measures than financial measures from the evaluations; (2) perceived CSR relevance is influenced by where evaluators stand in regard to CSR (“stakeholder view” in the “Perceptions of the Role of Ethics and Social Responsibility” or PRESOR scale) and also by where evaluators believe shareholders stand (shareholder support); and (3) there is a financial bias in appraisal and bonus decisions when CSR measures are used in the BSC, consistent with SVM ideology. We conclude by discussing the implications of the influence of SVM ideology on the use of CSR measures in terms of business research, practice, and education.     

Incentive effects in the demand for health care: a bivariate panel count data estimation

This paper contributes in three dimensions to the literature on health care demand. First, it features the first application of a bivariate random effects estimator in a count data setting, to permit the efficient estimation of this type of model with panel data. Second, it provides an innovative test of adverse selection and confirms that high‐risk individuals are more likely to acquire supplemental add‐on insurance. Third, the estimations yield that in accordance with the theory of moral hazard, we observe a much lower frequency of doctor visits among the self‐employed, and among mothers of small children.

Nachhaltigkeit in Wirtschaft und Gesellschaft

The scientific advisory board of the federal ministry of economic affairs and climate protection conducted a symposium on sustainability at its 500th meeting. The UN’s sustainable development goals play an increasingly important role in economic policy and regulation. This article gives a survey of the trade-offs and implementation problems that were discussed at the symposium, in particular the operationalisation of sustainability in welfare economics, the implementation of sustainability goals in economic law, the relationship between competition policy and sustainability, the impact of sustainability concerns on monetary policy, and finally, supply chain regulation and sustainability objectives.
