Malmquist indices of productivity change in Portuguese banking: The deregulation period

This paper will evaluate productivity change in Portuguese banking using the Malmquist productivity index. The results show that between 1990 and 1997, banks in Portugal witnessed increased productivity and strong technological progress. Both small and large banks experienced higher productivity and technological change scores, while mid-sized institutions are putting more effort into catching-up policies. Rural banks have experienced strong productivity growth and are catching up with the best practices but lower levels of technological change. Urban banks show higher productivity growth and technological change levels. Government-owned banks have experienced lower levels of productivity change. Finally, the asset per employee ratio shows a positive correlation with the productivity scores, suggesting that this simple index is a good proxy for productivity.     

Strategic decisions on bilateral bidding behavior: evidence from a wholesale electricity market

This article analyzes the strategic bilateral bidding behavior in the Spanish electricity wholesale market (OMEL). The collection of data includes information regarding weekly averages of spot prices, the quantity bid in the wholesale market, the quantities purchased in the wholesale market and sold in the open market, and the behavior of conduct parameters for the period from January 2002 to April 2007 for the four largest firms of the Spanish electricity market: Endesa, Iberdrola, Unión Fenosa and Hidrocantábrico. This article employs the New Empirical Industrial Organization approach. The empirical analysis was based on the autoregressive distributed lag approach to cointegration and on the Toda–Yamamoto Granger causality tests to validate the standard version of the theoretical formulation of the standard Cournot model, and its theoretical extension, to encompass the hypothesis of the presence of bid interdependence for electricity quantities sold and bought in the Spanish electricity wholesale market. The results of cointegration and causality analysis reinforce the empirical results of the extended Cournot model with the inclusion of the two main bidding variables that solved the optimization problem of profit maximization for each of the four firms analyzed.     

Competition in the Portuguese economy: insights from a profit elasticity approach

The article uses the elasticity of profits to marginal costs, as in Boone (Econ J 111:1245–1261, 2008b), to measure the degree of competition in the Portuguese economy in a period characterised by the reallocation of resources towards the non-tradable sector and the accumulation of macroeconomic imbalances. Using firm-level data for the period 2000–2009, we find that there is lower competition intensity in the non-tradable sector. The least competitive markets within this sector lay in professional services, network industries and segments of retail trade. We also find that reductions in competition intensity are relatively widespread in the economy, but in terms of sales, gross value added and employment they are more substantial in the non-tradable sector. Results suggest that some network industries and other services exhibit low and a declining competition intensity in the period under analysis. In addition, the article discusses the coherence of the profit elasticity with classic indicators of market power, such as the Herfindahl–Hirschman index and the price-cost margin, and find that in more than half of the markets there is an agreement in the dynamics of competition intensity.     

Single currency and fiscal performance: the early Euro Area in perspective

We examine how exchange rate regimes affect fiscal discipline by investigating European countries as they transitioned from flexible to fully fixed exchange rates under the Euro. We apply the synthetic control method to estimate, for each Eurozone country, its counterfactual budget stance under flexible rates. Our evidence strongly suggests that fixing exchange rates negatively impacted negatively fiscal discipline. However, effects were not homogeneous, as they were mediated by political factors. For example, countries where policymakers faced a longer political horizon and operated within a more cohesive political environment, managed to perform better in terms of fiscal discipline.     

A new approach to bad news effects on volatility: the multiple-sign-volume sensitive regime EGARCH model (MSV-EGARCH)

In this paper, using daily data for six major international stock market indexes and a modified EGARCH specification, the links between stock market returns, volatility and trading volume are investigated in a new nonlinear conditional variance framework with multiple regimes and volume effects. Volatility forecast comparisons, using the Harvey-Newbold test for multiple forecasts encompassing, seem to demonstrate that the MSV-EGARCH complex threshold structure is able to correctly fit GARCH-type dynamics of the series under study and dominates competing standard asymmetric models in several of the considered stock indexes.

The expectations hypothesis of the term structure of interest rates: The Brazilian case revisited

This article tests the Expectations Hypothesis (EH) using Brazilian monthly data for bond yields spanning the 2000–2017 sample period and ranging in maturity from 3 months to 5 years. Three tests are examined: the first is based on interest rates spread and the other two are based on the forward rates. On balance our results suggest rejection of the EH throughout the maturity spectrum examined, and are broadly consistent with previous findings that a linear combination of forward rates provides a statistically significant prediction of bond excess returns.     

Perceptions of Business Ethics in a Multicultural Community: The Case of Malaysia

Leaders and managers of today's multinational corporations face a plethora of problems and issues directly attributable to the fact that they are operating in an international context. With work-sites, plants and/or customers based in another country, or even several countries, representing a vast spectrum of cultural differences, international trade and offshore operations, coupled with increased globalisation in respect to political, social and economic realities, contribute to new dilemmas that these leaders must deal with. Not the least of these being a Code of Ethics and ethical decision making.This paper examines the differences in culture between a group of managers from the United States and similar group from Croatia using Hofstede's theory of International Cultures. The study explores how these cultural dimensions may help in our understanding of the differences in reported whistleblowing. The authors then postulate four hypotheses regarding various aspects of whistleblowing. These Hypotheses were than tested using a survey administered to a sample of U.S.A. and Croatian managers. Finally, the paper discusses the findings and practical implications for contemporary managers in the international arena.     

A single currency for the Economic Community of West Africa? An economic assessment

This paper assesses the economic support for the creation of an Economic Community of West African States (ECOWAS) monetary union encompassing all its 15 members, an objective that was set more than 30 years ago. In line with previous empirical research, our conclusion is that the adoption of a common currency by the whole region is not recommended. This work takes a step forward and assesses alternative ways to reduce the current number of currencies in circulation in the Community. Based on our results, we suggest (i) the merging of the currencies of Guinea, Liberia and Sierra Leone into a single currency and (ii) the Gambia to join the West African Economic and Monetary Union (WAEMU).     

The contribution of macroprudential policies to banks' resilience: Lessons from the systemic crises and the COVID-19 pandemic shock

This study examines the effectiveness of macroprudential policies in reducing the banks' risk during the COVID-19 pandemic and compares these results with the systemic banking crises years. Based on a sample of 624 banks across 40 countries during the period 2006–2020, we find that loosening capital-aimed macroprudential policies effectively reduced banks' risk during the COVID-19 pandemic, while this behavior led to increased risk during the systemic crises years. In contrast, tightening the remaining macroprudential policies during the systemic crises years and during the pandemic proved effective in reducing banks' risk. Furthermore, we show that the magnitude of the impact of macroprudential policies was stronger during the systemic crisis than that during the pandemic. Finally, we show that the results are driven by the capital requirement prudential policy, both during the systemic crisis and the COVID-19 pandemic, although the conservation buffer and the leverage limit also contributes to the ineffectiveness of these policies during the COVID-19 pandemic. The banks' leverage and loan growth also play an enhancing role of the effects of the macroprudential policies.
