We examine the extent to which market-access barriers in Latin America a ect small and large Peruvian exporters to the region. Using a dataset that allows us to distinguish between tariffs and different types of non-tariff measures introduced by Latin American countries between 2000 and 2014, we fi nd that large Peruvian exporters benefit rather than lose from the introduction of tariffs and non-tariff measures in their destination markets. Their export value increases and the probability that they exit the export sector decreases as they face new market-access barriers abroad. The reverse is true for small exporters, which are hurt by more stringent market-access barriers.
