Abstract: | In this paper we develop an open economy model of firms’ pricing behaviour under imperfect competition. This allows us to
introduce various terms of trade effects influencing the firm’s pricing decision, in addition to labour costs which dominate
most closed-economy specifications of the New Keynesian Phillips curve (NKPC). Our analysis gives rise to a hybrid open economy
NKPC which nests existing closed and open economy specifications adopted in empirical work. We estimate this specification
for the G7 economies and find that the US, UK and Canada typically enjoy less inertia in price setting than the European G7
economies and Japan and that these estimates are both plausible and in line with survey evidence. We also find that the proportion
of firms which use simple backward-looking rules of thumb in price setting is greater when the frequency of price change is
smaller. Finally there is evidence of significant asymmetries in price setting amongst EMU members.
