We use micro data on Irish producer prices to provide clean evidence on pricing-tomarket across a broad range of manufacturing sectors. We have monthly observations on prices charged by the same plant for the same product to buyers in Ireland and the UK, two markets segmented by variable exchange rates. Assuming that relative marginal cost is constant across markets within a plant and a product, this allows us to observe the behavior of the markup in the UK market relative to the home market. To identify pricing-to-market that goes beyond what is mechanically due to price stickiness, we condition on episodes where prices change. When prices are invoiced in local currency, conditional on prices changing, the ratio of the markup in the foreign market to the markup in the home market increases one-for-one with depreciations of home against foreign currency and decreases one-for-one with appreciations of home against foreign currency, a very particular form of pricing-to-market.

We compare the performance in employment, wages and productivity for domestic plants acquired by new domestic and foreign owners. Prospective foreign owners pick large, highwage, high-productivity plants, while new domestic owners choose average performers of above-average size. Employment, labour productivity, and total factor productivity decline in domestic acquisition targets before acquisitions; only wages recover afterwards. Employment, wages and labour productivity increase after foreign acquisitions. The sample selection introduced by long-term comparisons and a focus on unique events introduces a downward bias into the results for domestic acquisitions and an upward bias for the foreign acquisitions.

We analyse factors driving inter-and intra-firm diffusion of ICT using data from Irish manufacturing firms over the period [2001][2002][2003][2004]. We find that the path of ICT diffusion has been uneven across firms, industries and space, which is consistent with the theory of new technology adoption. Our results suggest that firms which are larger, younger, fast-growing, skill-intensive, export-intensive and firms located in the capital city region have been relatively more successful in adopting and using ICT. We find positive technology spillovers from firms that have adopted ICT located in the same industry and region.

We estimate the effects of adopting DSL broadband on firm productivity and productivity growth allowing for differing broadband speeds. We use a two-stage least squares estimator with geographical broadband availability as an instrument to address some potential endogeneity problems in a panel of Irish manufacturing firms. While more productive firms are on average more likely to be using DSL broadband, we find no statistically significant effect of broadband adoption on firms' productivity (growth).

We document how export quantities and prices evolve after entry to a market. Controlling for marginal cost, and taking account of selection on idiosyncratic demand, there are economically and statistically significant dynamics of quantities, but no dynamics of prices. To match these facts, we estimate a model where firms invest in customer base through non-price actions (e.g. marketing and advertising), and learn gradually about their idiosyncratic demand. The model matches quantity, price and exit moments. Parameter estimates imply costs of adjusting investment in customer base, and slow learning about demand, both of which generate sluggish responses of sales to shocks.
