Reversion rate of deviations from purchasing power parity for Brazilian cities / Velocidade de reversÃo dos desvios da paridade do poder de compra para cidades brasileiras

Felipe de Sousa Bastos 17 January 2014 (has links)
Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico / This work aims to provide non-biased estimates of the speed of reversion of deviations from the PPP for 11 Brazilian cities, between 1991 and 2013, using the methodology proposed by Choi, Mark and Sul (2006), which makes use of a panel estimation method with correction for three possible sources of bias, those being: the bias of inappropriate grouping of cross-section units with heterogeneous coefficients, the Nickell bias and the bias arising from the temporal aggregation of price indexes. The half-lives obtained are of the order of 4.41 and 3.18 years with Brazil and the Average as references, respectively, and median half-life of 3.13 years, when considering all Brazilian cities analyzed as the numeraire. The half-lives found were also substantially lower than those obtained for American cities. Furthermore, 33.33 % of the half-lives obtained were inferior to the consensus range suggested by Rogoff (1996) of 3-5 years, and none surpassed that range. / O presente estudo se propÃe a prover estimativas nÃo viesadas da velocidade de reversÃo dos desvios da PPC para 11 cidades brasileiras entre 1991 e 2013 atravÃs da metodologia proposta por Choi, Mark e Sul (2006) que usam um mÃtodo de estimaÃÃo em painel com correÃÃo para trÃs possÃveis fontes de viÃs, quais sejam, viÃs de agrupamento inapropriado de unidades cross-sections com coeficientes heterogÃneos, viÃs de Nickell e o viÃs oriundo da agregaÃÃo temporal dos Ãndices de preÃos. As meias-vidas obtidas sÃo da ordem de 4.41 e 3.18 anos tendo Brasil e MÃdia como referÃncia, respectivamente, e meia-vida mediana de 3.13 anos considerando todas as cidades brasileiras analisadas como numerÃrio. As meias-vidas encontradas tambÃm se mostraram substancialmente inferiores Ãquelas obtidas para as cidades americanas. AlÃm disso, 33.33% das meias-vidas aqui obtidas se mostraram inferiores ao intervalo consensual proposto por Rogoff (1996) de 3 a 5 anos, e nenhuma o ultrapassou.
