Purpose We extend a classic macroeconomic framework guided by extensive empirical and theoretical literature on growth transmission channels shock decomposition, with the purpose of measuring spillovers from G-10 countries to US. Design/methodology/approach use time-varying parameter vector autoregressive (TVP-VAR) model dynamic structures measure external spillover effects under different economic conditions, i.e. controlled representative set American variables. Findings Based our exercise...
We add to the discussion on role of debt-to-GDP and inflation in U.S. real GDP per capita its variation from 1966 2022. use Global Wavelet Power Spectrum, Multivariate Coherency Partial Coherency, Phase-Difference Gain. find complex phasic anti-phasic co-movements between business growth cycles versus debt cycles. Moreover, most relationships are given by leadership (zero 4-year frequency period), while can lead opposite direction 8-year period). have interesting findings over NBER...
Diante do quadro de expansão da rede educação superior, este estudo se propõe a analisar o impacto das Universidades Federais sobre desenvolvimento local dos municípios brasileiros, baseado em indicadores econômicos, sociais e mercado trabalho. Além disso, busca-se identificar os fatores que influenciaram serem contemplados com um campus Universidade. Para isso, emprega-se método pareamento escore propensão objetivo construir grupo controle mais assemelha ao tratamento. E, para estimar...
We examine volatility connectedness of 11 sectoral indices in the US using daily data from January 01, 2013 to December 31, 2020. employ measures Diebold and Yilmaz (2009, 2012, 2014), unveiling changes stylized facts regarding specific sectors occurred during COVID-19 pandemic. Among several results, we find extraordinary increase COVID-19, earlier stages international spread end July 2020; considerable pairwise relationships, especially among upper two deciles. However, a total net...
Recent research suggests that one of the main motivations for mergers and acquisitions is attempt to acquire companies incorporate intangible assets. Such assets provide important sources sustainable competitive advantages opportunities growth. This article analyzes strategies engineering companies, as well value creation in acquisition events multinational by using study method, providing an innovative way be applied this phenomenon. method used our influence announcement on abnormal...
We revisit the discussion on banking system contagion by proposing a risk-based empirical analysis during current pandemic period. use daily returns G7 sector indices from 1 January 2015 to 31 December 2019 (pre-pandemic), and 2020 16 October (pandemic). Based dissimilarities, has intensified contagion. Frequency-based Granger causality is useful tell history of pass-through this health crisis across sectors. highlight increase in predictive relevance Italian cycles pandemic. VaR ratio...

We address G7 banking contagion during the COVID-19 crisis using wavelet-based techniques. find an increase (20%) of lowest frequencies pandemic period based on stronger coherence between all pairs financial indices. also that world cases and deaths are relevant to understand cycles co-movements, mainly from February June. Our findings confirmed by a correlation test still hold after controlling for oil prices.
Resumo Este trabalho avalia a eficiência preditiva dos modelos de curva Phillips com e sem modelagem ARMA seus resíduos, considerando uma amostra que contém países desenvolvidos em desenvolvimento. O objetivo principal deste estudo é fornecer evidências empíricas essa simples reformulação da Curva pode servir benchmark para estudos propõem econométricos ou séries temporais mais elaborados prever taxa inflação. Os resultados mostram o uso componentes nos resíduos diminuem consideravelmente...
Diversification in a portfolio is an important tool for the systematic risk management that inherent to different asset classes. The composition of with domestic and international assets seen as one main alternatives building diversified portfolio, this approach tends reduce return exposure depending on country factors. However, scenarios where industry factors are predominant, diversification can increase centered single class. This study pioneer using wavelet-based methods identify...
We study the Brazilian stock market response to COVID-19 pandemic. Considering data from January 22, 2020, August 31, 2021, and a daily dataset comprised of Bovespa index - main performance indicator stocks in capital -, its sector components, cases deaths most affected countries, we employ wavelet tools partial coherences, phase differences, dissimilarities, VaR ratio.We find significant coherence spots, decrease dissimilarity, increase ratio suggesting responded forcefully local...
A agenda política nacional tem ampliado a atenção sobre importância de mecanismos incentivo e/ou compensação para promoção melhorias no desempenho educacional básico. Nesse sentido, regra distribuição da quota-parte do ICMS1 Ceará é considerada um importante benchmark em termos estratégicos. Na medida que recursos estado passou ser vinculada à qualidade dos municípios, o desenho mecanismo adotado possui capacidade alinhar os objetivos gestores municipais relação às preferências estado,...
We add to the discussion on role of debt-to-GDP and inflation U.S. real GDP per capita its growth rate during period from 1966 2022. use Global Wavelet Power Spectrum, Multivariate Coherency Partial Coherency, Phase-Difference Gain. This framework enables us work with heteroskedastic non-stationary data. find complex phasic anti-phasic relations between business cycles, versus debt inflation. To summarize, most relationships (zero 4-year frequency period) are characterized by leadership...
We exploit a decade of bimonthly fiscal dataset the state government Ceará to search for systemic relationship between public capital, debt and cash.We add empirical literature on investment sustainability by using an integration vector model, impulseresponse conditional multivariate wavelet framework.We find long-term characterized negative (positive) reaction investments increase in (cash).Debt cash shocks impact after seven bimesters expected directions, such responses do not dissipate...
O artigo utiliza a decomposição de tendências e ciclos comuns Vahid Engle (1993) para verificar presença co-movimentos curto longo prazo entre as taxas inflação das regiões metropolitanas do Brasil, durante o período outubro 1995 até dezembro 2014. Os testes comprovam existência duas estocásticas seis comuns. resultados apontam inter-relações positivas trajetória estudadas. As séries apresentaram também um comportamento similar prazo, sendo caracterizadas como pró-cíclicas.
Resumo Este artigo analisa o comportamento mensal da produção industrial dos estados Bahia, Minas Gerais, Pernambuco, Paraná, Rio de Janeiro, Grande do Sul e São Paulo, no período 2002:01 até 2014:12, através metodologia tendências ciclos comuns Vahid Engle (1993). Os testes comprovam a existência duas cinco comuns. resultados apontam que desvios equilíbrio longo prazo na atividade Paulo influenciam trajetória demais estudados, ao passo choques permanentes afetam efetivamente apenas dinâmica...
O estudo das relações de longo prazo entre os gastos públicos e o nível renda é fundamental para auxiliar formadores políticas públicas na tomada decisão, sobretudo quando a análise se concentra nas componentes do gasto. Adotou-se como estratégia econométrica metodologia CS-ARDL-DFE, estados brasileiros no período 1986-2013, nos moldes sugeridos por Chudik & Pesaran (2015). Os resultados apontam que as despesas exercem impacto positivo sobre crescimento econômico prazo, com capital...
