This paper investigates the Chicago Board Option Exchange Volatility Index's ('VIX') response to COVID-19 pandemic crisis, in terms of information efficiency. First, we estimate an Efficiency Index over rolling windows, based on closing levels, for a period between 1995-01-03 and 2020-12-30. Second, check presence deterministic chaos efficiency series, by using largest Lyapunov exponent sample, as well permutation entropy. However, do not find that these estimators provide clear evidence...

Abstract The United Nations' 2030 Agenda for Sustainable Development proposes the ambitious goal of an inclusive and sustainable economy. Thus, a realistic assessment individual countries' possibilities to implement Goals might provide helpful insights. We seek contribute existing literature by proposing working framework assessing, at country level, impact long‐run economic growth on societal development. is based composite models from Structural Equation Modeling‐SEM with Partial Least...

The continuous wavelet transform analysis may provide a rich and flexible framework for the of time series which exhibit less stable statistical properties, such as ones describing dynamic trajectory capital markets. In contrast to Fourier analysis, preserves information on both frequency. We summary most important features this framework. By involving concept coherence well its partial multiple forms, we analyse connections between Santiago Stock Exchange, Mexican Exchange BM&FBOVESPA São...

Abstract A stochastic volatility estimation of VIX index’s latent is used for the United States America, as a proxy adjustments in levels investors’ uncertainty related to current and future economic policies. The impact monetary policy stance on such measure examined framework distributed lag non-linear models (DLNM). We place this analysis literature stream emphasizing various sources heterogeneity concerning expectations. main finding that does non-linearly predictions. While tighter...

This paper uses data for the 27 Member States of European Union (EU) from 2000 to 2010 support thesis that a positive and significant correlation exists between nation's quality governance its economic output. To achieve this goal, elements have been reported by Worldwide Governance Indicators project are considered. Four individual indicators policies institutions global indicator constructed. We estimate that, our database, standard deviation shock in these causes changes 0.03-fold...

The intangibles can be viewed as strategic assets, since their inclusion in the structure of total assets allows economic entities to extract a "competiveness rent" and, thus, enhance outcomes activity.This paper seeks provide some empirical evidences for effects exercised by shocks emerged at level intangible-to-total ratio on profitability case 562 large companies listed Frankfurt Stock Exchange and London Exchange.We found that, full sample, there is relatively steady relationship between...

This paper investigates the relationship between intra-industry trade (IIT), horizontal IIT, vertical IIT (VIIT) and immigration flows using a gravity model for period 1995-2008 amongst Portugal European Union’s Member States (EU-27). Using panel data approach, results show positive correlation IIT. These outcomes indicate that can reduce transaction costs home host country. We also consider economic dimension which appears to exercise effect on trade. Our research confirms hypothesis there...

The core argument of this paper is that International Financial Reporting Standards (IFRSs) are designed to provide relevant financial information a wide range users. higher the quality supplied by reporting, better outcomes decision–making process participants on capital markets and lower asymmetry within markets. working hypothesis changes in reporting for joint ventures can reduce issues. Our approach takes into consideration recently issued IFRS 11, which critical importance nature...

This study is focused on the linkages between legislative families as descriptors of national systems and International Financial Reporting Standards (IFRSs) issued by Accounting Board (IASB). We consider such analysis a case for more general issue explaining preferences regulators in adoption foreign norms, rules, standards practices. By using dataset 162 jurisdictions dummy variables designed to capture current stage IFRSs and, respectively, taxonomy their systems, we find that full likely...

In the present paper we discuss forecasting ability of VaR model, within context a Generalized Autoregressive Score (GAS). The proposed method considers an Asymmetric Laplace Distribution (GAS-ALD) to describe daily log-returns analyzed data. A forecastability indicator for certain probability is proposed. approach uses back-testing and several unconditional conditional tests, see whether or not GAS-ALD model accurately describes specificity log-returns' distribution. Our results show strong...

This study examines the Eurozone stock markets' reaction to a number of events associated with post-implementation amendments IFRSs regarding financial instruments (IFRS 7, IFRS 9, IAS 32 and 39).The adoption these is probably one most important recent changes in information environment.However, order contribute an increase stability, it necessary ensure ex post stability regulatory framework.Based on this meta-argument, we have analyzed interlinkages between episodes higher market...

The spread of the COVID‐19 pandemic has severely impacted all aspects social and economic life, including evolution stock markets. Thus, we advance a methodological framework suitable for assessing 2020 year‐long shifts in markets’ statistical complexity, apply such to ten major international developed or emerging Our research reveals that this crisis had considerably altered evolutionary patterns. network description multivocal transmission complex responses changed 2020, European Asian...
