This paper revisits the D-S (Dixit-Stiglitz) model. It’s a simple general monopolistic model with n monopolistic goods, and a numeraire good Labour ( w=1); aggregation for all goods in the economy. We have considered in our paper constant elasticity of substitution case(CES).On the supply...

Due to isoelastic demand and constant marginal cost it is optimal for firms to set the output price as a fixed markup over the nominal wage. When demand shocks occur, firms' first response...

The main purpose of this study is to illustrate, with a simple monopolistic competition trade model, how trade liberalization (i.e., a decline in trade costs) can affect domestic entrepreneurs' decisions between domestic brands and foreign brands, and thus the degree of foreign brand...
