【 摘 要 】

Whether gains from trade are equally distributed within countries is the subject of a lively debate. This paper presents a novel framework to analyse the distributional effects of trade policy by linking the OECD’s CGE trade model, METRO, with consumption expenditure data from household budget surveys. Specifically, this paper describes a methodology to produce a concordance and transition matrix linking GTAP sectors to household survey classifications based on the Classification of Individual Consumption According to Purpose (COICOP). A mapping methodology is an important pre-requisite for investigating research questions concerning the influence of household behaviour changes on trade, as well as trade developments and policy on household welfare. The paper provides an illustration of the mapping of trade policy induced price changes onto household expenditures by conducting stylized tariff simulations with METRO and translating those into household expenditures by income decile for selected EU countries.
