| Summary: | The literature on the relationship
between economic diversification and development has grown
rapidly in recent years, partly due to the surprising
finding that diversification rises with gross domestic
product per capita up to a certain point. Export
diversification along the extensive margin is inextricable
from the introduction of new export products. The authors
test the hypothesis that the threat of imitation inhibits
the introduction of new exports -- export discoveries --
under the assumption that the intensive and extensive
margins of exports are correlated within broad
country-industry groups. Econometric evidence from
panel-data techniques that are appropriate for count data
(the number of discoveries) suggests that discoveries within
countries and industries rise with the growth of exports
along the intensive margin (relative to the growth of
non-export gross domestic product) but the magnitude of this
partial correlation increases with domestic barriers to
entry and with customs delays in exporting. However, the
magnification effect of barriers to entry appears to be less
significant as a determinant of total within-country export
discoveries. This is consistent with inter-industry and
within-country spillovers related to export discoveries,
implying that barriers to entry enhance the effect of export
growth on discoveries within country-industries but total
discoveries might be unaffected by barriers to entry. |
