| Summary: | Product variety plays an important role
in the theoretical work on monopolistic competition and
trade, and recent empirical work has begun to quantify this
for aggregate and disaggregate import demands. The authors
discuss the measurement of product variety in trade, using a
broad cross-section of industrial and developing countries
and disaggregating across sectors. The authors calculate the
export variety of countries in their sales to the United
States, and relate the export variety indexes to country
productivities. They confirm that countries with greater
product variety in exports also have higher productivity.
This may be due to their development of and access to these products. |
