Regional inflation dynamics using space–time models

This article provides empirical evidence of the role of spatial factors on the determination of inflation dynamics for a representative set of tradable commodities in Chile. We present a simple model that explains inflation divergence across regions in a monetary union with similar preferences as a consequence of the geographical allocation of producers in the different regions. Our results indicate that spatial allocation together with transport costs are important determinants of regional inflation, while macroeconomic common factors do not play an important role in this process. Existing literature had obtained the opposite result for Europe, and the reasons for this difference warrant further investigation. Moreover, we find that geographical distance seems to be a more appropriate measure of neighbourhood than the adjacency of regions. Our results are robust to different specifications, regression methods and product groupings.     

Renewable energy drivers: a panel cointegration approach

The expected gains from RES deployment to the reduction of carbon dioxide emissions (CO₂) and the cut-off of external dependence of electricity sources could be important. However, it is crucial to understand the determinants of RES growth to help policymakers drawing effective energy polices, involving a commitment of both citizens and governments. In this paper, we use novel panel econometric tools (taking into account structural breaks and cross-section dependence) and find evidence of nonstationary issues and cointegration issues between renewable energy production and its drivers (CO₂ emissions, GDP per capita, energy use and dependency). The results thus reveal that non-stationary issues should be attended, otherwise they could be biased. Using suitable estimators (DOLS, FMOLS) with two different data sets and different proxies and taking common factors into account by MG estimates, we find that there is no environmental concerns effect explaining the growth of renewables in European countries. However, national revenues, energy consumption (demand effect) and energy dependency have a positive impact on renewables deployment. Considering these results, economic assistance (subsidies) might be a mean to increase further the renewables deployment in EU countries and education about renewables deployment is needed.     

Choosing an optimal investment strategy: The role of robust pair-copulas based portfolios

This paper is concerned with the efficient allocation of a set of financial assets and its successful management. Efficient diversification of investments is achieved by inputing robust pair-copulas based estimates of the expected return and covariances in the mean-variance analysis of Markowitz. Although the whole point of diversifying a portfolio is to avoid rebalancing, very often one needs to rebalance to restore the portfolio to its original balance or target. But when and why to rebalance is a critical issue, and this paper investigates several managers' strategies to keep the allocations optimal. Findings for an emerging market target return and minimum risk investments are highly significant and convincing. Although the best strategy depends on the investor risk profile, it is empirically shown that the proposed robust portfolios always outperform the classical versions based on the sample estimates, yielding higher gains in the long run and requiring a smaller number of updates. We found that the pair-copulas based robust minimum risk portfolio monitored by a manager which checks its composition twice a year provides the best long run investment.     

Effects of traits,self-motivation and managerial skills on nursing intrapreneurship

Following the introduction of quasi-markets into publicly funded healthcare systems, nurse intrapreneurs who create innovations within these systems have become increasingly important to improving healthcare outputs. This study sought to examine how self-motivation and managerial skills mediate the influence of entrepreneurial traits on nurses’ intrapreneurial intentions in the Portuguese National Health Service. A structural equation model was assessed using primary data collected from a sample of 536 nurses working at seven public hospitals in Portugal. The results suggest that nurses who are more determined to become intrapreneurs are more likely to take risks, more self-confident about their managerial skills and slightly more self-motivated. In addition, while innovativeness has no significant effect, proactivity contributes to increasing nurses’ self-confidence in their own skills.

     

Behavioral Finance in Brazil: A Bibliometric Study from 2007 to 2017

This article analyzed 58 Brazilian journals in order to address the gap unexplored in the past 10?years by congresses and periodical journals. In this research, an analysis based on keywords was used, followed by analysis of citations and co-citations that allowed to verify: an average growth of 20% p.a. of publications; the most common focus was replication of Kahneman and Tversky; the most studied group tended to be university students; quality has failed to accompany the increase in publications; public institutions publish more. A gap was perceived in the surveying of financial managers and investors, as well as bias and heuristics as a subject.     

SEC interventions and the frequency and usefulness of non-GAAP financial measures

This paper examines the effect of two Securities and Exchange Commission regulatory interventions related to disclosure of non-GAAP financial measures. There are three main results. First, the probability of disclosure of non-GAAP earnings declines in 2003, but the probability of disclosure of other non-GAAP financial measures has an accelerated decline after the first intervention. Second, all else equal, after Regulation G, investors have a positive market reaction to the disclosure of non-GAAP earnings. Finally, investors react to the adjustments made by I/B/E/S financial analysts as they do to the GAAP surprise, but they do not react to the additional adjustments made by firms.     

Understanding the dynamics behind bank branch service quality in Portugal: pursuing a holistic view using fuzzy cognitive mapping

Using fuzzy cognitive mapping, this study aims to create a holistic framework whereby the determinants of bank branch service quality and their cause-and-effect relationships can be identified and dynamically analyzed. The methodology is applied using a group of experts from the banking industry in Portugal. Our results not only indicate the applicability and usefulness of the proposed approach, but identify human resource characteristics (which include collaborators’ personal and professional training) and management team technical skills as particularly relevant driving forces of bank branch service quality. The proposal holds great potential for the operational planning and improvement of bank branch service quality, which is a prime concern for bank administrators, bank branch collaborators, and society at large. Advantages and shortcomings of the framework are also reported.     

The influence of culture and transparency on global research and development intensity: An overview across Europe

Culture and transparency can be described as a set of beliefs, norms, and actions, which drive the human action into innovativeness. Over the centuries, those pillars have driven individuals, groups, organizations, and nations, into the most complex networking schemes. It seems now unquestionable that those beliefs and policies, affect both private and public organizations, driving them across innovation wages in a more incremental or radical way. The dependent variable in this research (R&D) embodies the disbursements in research and development, carried out by business enterprise and public sector, and by education institutions. Thus, this research aims to mainly explore the effect of culture and transparency, as drivers of business attractiveness, on global R&D intensity. Using information from 31 European countries over the period 2010–2014, total R&D expenditures were regressed against several variables such as the Hofstede's cultural dimensions, the public sector transparency index, and other aggregated variables. Most of the theoretical assumptions are now supported by our empirical outcomes. Culture and transparency can act as attractiveness drivers, for business sector organizations and for other private and public institutions, toward the implementation of knowledge transformation mechanisms and intellectual capital achievements.     

Joined-up Government of utilities: a meta-review on a public–public partnership and inter-municipal cooperation in the water and wastewater industries

Private-sector participation in public services delivery has been criticized due to unfulfilled expectations. In response, joined-up government is being introduced as an alternative approach to providing water and wastewater services. This approach involves the establishment of horizontal (i.e. inter-municipal cooperation) and vertical (i.e. public–public partnership) integration. Drawing on a meta-review focused on the water and wastewater industries, this study shows that both arrangements have positive aspects, such as cost savings. However, contractual schemes and inter-departmental coordination efforts must be carefully managed or they will fail. In addition, research on cooperation between public bodies is scarce and must be better coordinated concerning study aims and methods.
