Real-world industries are composed from heterogeneous firms and substantial intra-industry reallocations take place, i.e. high productivity firms squeeze out low productivity firms. Previous tax-tool comparisons have not included these central forces of industry structure. This paper examines a...

The marginal costs based representation of firm productivity in the Melitz [Melitz, M.J., 2003. The impact of trade on intra-industry reallocations and aggregate industry productivity. Econometrica 71 (6), 1695-1725] model, predicts positive exporter productivity premia. We show that this...

Why is it that exporter productivity premia (EPP) differ so widely in size? We take this question to the theory and to the data. We derive the sectoral EPP in a standard heterogeneous firms trade model and apply the insights from the model to 13 years of data for all Danish manufacturing firms....

This paper deploys a dynamic extension of the Melitz (2003) model to generate predictions on export market exit and firm survival in a setting where firms endogenously make exit decisions. The central driver of the model dynamics is the inclusion of exogenous economy wide technological progress....

International integration strengthening intra-industrial trade may have important implications for employment, wages and inequality. The reason is that product market integration enhances export possibilities through easier access to foreign markets, but also import threats arising from foreign...

International product market integration enhances both export possibilities through easier access to foreign markets, but also the import threat arising from foreign firms penetrating into the domestic market. These mechanisms affect wage formation and employment creation through many channels...

This paper shows that the novel gains from trade liberalization driven by intra-industry reallocations (Melitz (2003)) are not robust to changes in the preference structure. In the Melitz (2003) setting the unambigousness of the welfare effect depends crucially on the assumption of traditional...

Will the current employment crisis produce lost generations with permanently lower labour market attachment? Taking an explicit cohort perspective and based on Danish data we do not find strong persistence in employment rates at the cohort level. Younger workers tend to be more exposed to...
