What determines whether or not multinational firms transplant the mode of organisation to other countries? We embed the theory of knowledge hierarchies in an industry equilibrium model of monopolistic competition to examine how the economic environment may affect the decision of multinational...

We derive exact conditions relating the distributions of firm productivity, sales, output, and markups to the form of demand in monopolistic competition. Applications include a new “CREMR” demand function (Constant Revenue Elasticity of Marginal Revenue): it is necessary and sufficient for...

In this paper, we zoom in on the firm level of German merchandise foreign trade, using a novel data base with information on the export and import value by firm, country, product and year for the period 2011-2019. Problems arising from the consolidated reporting of taxable entities and the...

This paper explores the quantitative consequences of transatlantic trade liberalization envisioned in a Transatlantic Trade and Investment Partnership (TTIP) between the United States and the European Union. Our key innovation is to develop a new quantitative spatial trade model and to use an...

In this paper we want to shed some light on the empirical relevance of the new economic geography. Using one of the central features of the core new economic geography models, namely that wages have the tendency to fall the further one moves away from centres of economic activity, we investigate...

This paper uses an oligopoly model with heterogeneous firms to examine how an industry adjusts to rising import competition. The model predicts that in the short run the least efficient firms in the industry become inactive, surviving firms face a fall in output, mark-ups and profits, and the...

When employers face a trade-off between growing large and paying low wages - that is, when they have monopsony power - some productive employers will decide to acquire fewer customers, forgo sales, and remain small. These decisions have adverse consequences for aggregate labor productivity....

Increasing wage inequality between similar workers plays an important role for overall inequality trends in industrialized societies. To analyze this pattern, we incorporate directed labor market search into a dynamic model of international trade with heterogeneous firms and homogeneous workers....

This paper develops a quantitative spatial general equilibrium model for the German economy to address two issues. First, we explore the role of commuting for local labor markets and their capacity to absorb productivity shocks. Second, we address the role of housing markets for quantitative...

This paper uses the quantitative spatial model with heterogeneous locations linked by costly goods trade, migration and commuting developed in Monte et al. (2018) to address the workings of local labor markets in Germany. One key contribution concerns the analysis of the role of the expenditure...
