- PublicationProductivity is higher among some service firms when broadband becomes available, but not allUsing internet services over broadband connections may help some firms become more productive, generating more output from a given amount of labour and capital equipment. However, there is mixed evidence internationally about how large this benefit has been in practice and which types of firms are most likely to improve their productivity by using these technologies. In this research we examine the effects of broadband availability on the productivity of service sector firms.
176 - PublicationIntra-firm trade, exporting, importing and firm performanceThis paper examines firm heterogeneity in terms of size, wages, capital intensity, and productivity between domestic and foreign-owned firms that engage in intra-firm trade, firms that export and import, firms that import only, and firms that export only. As previously documented, heterogeneity between different groups of trading firms issubstantial. Taking into account intra-firm trade in addition to exporting and importingyields new insights into the productivity advantage previously established for exportingfirms. The results presented here show that this premium accrues only to exporters thatalso import and to exporters that also engage in intra-firm trade, but not to firms that export only. Using simultaneous quantile regressions, the paper illustrates that heterogeneity within different groups of trading firm is equally large. Some of this within-group heterogeneity can be attributed to differences in trading partners
