David de la Croix and Jean-Pierre Urbain, "Intertemporal Substitution in Import Demand and Habit Formation", Journal of Applied Econometrics, Vol. 13, No. 6, 1998, pp. 589-612. The data we use in this paper are quarterly seasonally adjusted data covering the period 70:01-94:01 for France (97 observations) and 67:01-94:03 for the USA (111 observations). French data are built on the basis of the quarterly national accounts (Comptes nationaux trimestriels (INSEE)). Non-durables include subsectors U02 (meet and milk products, other products from food industry) and U06 (drugs, textiles, clothing, shoes, leather, furnitures, printing). For the USA, both the source and the construction of the data follow Ceglowski (1991) for an extended sample size. The required rate of return is the short-run real return (three-month treasury bill rate for the US and "taux de l'argent au jour le jour des effets prives" for France) plus a constant risk premium of 2 percent per quarter. The files USDAT.TXT and FRDAT.TXT, which are in DOS format and are zipped in du-data.zip, contain the data series analysed in the paper. Data are reported by column, as follows Column 1 ===> Imported non-durable consumption goods (volume). Column 2 ===> Domestically produced non-durable consumption goods (volume). Column 3 ===> Price of imported non-durable consumption goods. Column 4 ===> Price of Domestically produced non-durable consumption goods. Column 5 ===> Nominal interest rate David de la Croix IRES - Universite catholique de Louvain Place Montesquieu 3 B-1348 Louvain-la-Neuve, Belgium mail delacroix@ires.ucl.ac.be www http://www.econ.ucl.ac.be/ires/csssp/home_pa_pers/delacroix/delac.html
