Fuel price transmission mechanisms in Portugal, “Working Paper Series” nº 18/11, 30 pp.. Ponta Delgada: Universidade dos Açores, CEEAplA-A.http://hdl.handle.net/10400.3/4963This study aims to analyze the behavior of fuel prices at the pump (unleaded gasoline and diesel) in Portugal, relative to positive and negative variations in Brent Crude Oil prices. Applying an autoregressive distributed lags model (ARDL) to weekly time series data for the period of January 2004 through May 2009, we detected some signs of asymmetry in the transmission price mechanism. However, these patterns are not statistically significant enough to reject hypotheses of symmetry in the price adjustment mechanisms of fuels in Portugal.engFuel and Oil PricesPrice Adjustment Mechanismsworking paper
