“…As CMS (2006), they corrected the estimates for the Nickell and temporal aggregation biases and obtained a median half-life of 3.13 years, ranging from 2.55 to 3.84 years, slightly shorter than that proposed by Rogoff (1996). Arruda et al (2015) analyzed the evolution of relative prices of Brazilian cities from 1995 to 2012 to identify stylized facts on the convergence of prices and speed of reversion to PPP. They found evidence of a reduction in the absolute dispersion of the prices in Brazilian cities and the variability of relative prices.…”

“…BAF (2014), reported a median half-life of approximately 3.13 years considering the 11 metropolitan regions covered by the survey used to compute the Consumer Price Index (IPCA) as numeraires. Arruda et al (2015) found average half-lives of 19, 27 and 42 months when using, respectively, the mean IPCA of the cities, the national IPCA and the IPCA of São Paulo as numeraires.…”

“…Para lidar com dados em que estes problemas são de menor importância, uma vertente de estudos relacionados à PPC dedica-se à investigação da convergência de preços relativos em cidades de um mesmo país ou entre nações pertencentes a regiões econômicas com moeda única. Para a economia brasileira, Arruda et al (2015) usam séries de tempo do Índice de Preços ao Consumidor Amplo (IPCA) para as regiões metropolitanas (RMs) brasileiras usadas na construção do índice e reportam uma meia-vida média de 27 meses. Com os mesmos dados, mas em uma estrutura de dados em painel, Bastos, Ferreira e Arruda (2018) reportam uma meia-vida mediana de aproximadamente 38 meses, dentro do intervalo-consenso.…”

“…Com os mesmos dados, mas em uma estrutura de dados em painel, Bastos, Ferreira e Arruda (2018) reportam uma meia-vida mediana de aproximadamente 38 meses, dentro do intervalo-consenso. É importante destacar que, em Arruda et al (2015), não há correção para o viés de pequenas amostras do estimador OLS, nem é dado tratamento adequado ao viés de heterogeneidade setorial apontado por IMRR (2005a). Adicionalmente, o cálculo da meia-vida não é realizado como sugerem Kilian e Zha (2002) e Seong, Morshed e Ahn (2006).…”
