This paper shows that the diverging results obtained in the literature on the firm size-growth relationship can be reconciled in a very general theoretical framework featuring firm-level heterogeneity and investment decision. Three main elements determine the nature and the intensity of the relationship between firm-level size and investment: the shape of(More)
Do variations in labor market institutions across countries affect the cross-border organization of the firm? Using firm-level data on multinationals located in France, we show that firms are more likely to outsource the production of intermediate inputs to external suppliers when importing from countries with empowered unions. Moreover, this effect is(More)
We analyze the impact of trade integration on plant TFP using Chilean plant-level data (1982–1999) and 3-digit bilateral trade flows. Our contribution is to disentangle the impact of export and import barriers, estimated as border effects within a multilateral context. A fall in export barriers is positively correlated with plant productivity in traded(More)
We extend the trade model with firm heterogeneity developed by Melitz and Ottaviano (2008), incorporating domestic and imported intermediate goods, in order to investigate the impact of import barriers on final and intermediate goods on firms’ decisions to produce and to export. Our main contribution is to disentangle the channels through which these trade(More)
Although firms are dispersed across space and may face radically different production conditions, this dimension of firm heterogeneity is often overlooked. Differences between factor markets, especially for labor, are stark. To pursue this line of inquiry, we model firm hiring across local labor markets. We then use the model to estimate and quantify the(More)
This paper develops a model of trade that features heterogeneous rms, technology choice and di erent types of skilled labor in a general equilibrium framework. Its main contribution is to explain the impact of trade integration on technology adoption and wage inequalities. It also provides empirical evidence to support the model's main assumption and(More)
Models of heterogeneous firms with selection into export market participation generically exhibit aggregate trade elasticities that vary across country-pairs. Only when heterogeneity is assumed Paretodistributed do all elasticities collapse into an unique elasticity, estimable with a gravity equation. This paper provides a theory-based method for(More)
We investigate the e ect of di erent channels through which input trade liberalization a ects rms' decisions such as whether to produce or shut down and whether to sell on the foreign market. The main contribution of this paper is to develop a trade model with heterogeneous rms, that reproduces di erent mechanisms through which the access to foreign inputs(More)

In contrast to other areas of the planet, very little is known about Antarctic marine invertebrates associated with eutrophic marine benthic areas. Recently, several studies investigated this fauna by experimentally deploying whale bones, leading to the discovery of new opportunistic polychaetes. To investigate the Antarctic organisms associated with these(More)
