This paper quantifies the origins of firm size heterogeneity when firms are interconnected in a production network. Using the universe of buyer-supplier relationships in Belgium, the paper develops a set of stylized facts that motivate a model in which firms buy inputs from upstream suppliers...

We use Belgian data with information on domestic firm-to-firm sales and foreign trade transactions to study how international trade affects firm efficiency and real wages. The data allow us to accurately construct the domestic production network of the Belgian economy, revealing several new...

During the recent decades, multitasking has become a more and more common phenomenon at workplaces. Rather than specializing in a job task, workers perform bundles of tasks. Bundling occurs when tasks are complements. Using individual-level data about job tasks, we analyze which tasks are...

One of the most important predictions made in recent international trade literature based on heterogeneous firms concerns the within-industry job reallocation from firms not involved in international markets to those that are. This paper quantifies the extent of this reallocation using a dataset...

This volume was prepared by Inga Heiland while she was working at the Ifo Institute. It was completed in July 2016 and accepted as a doctoral thesis by the Department of Economics at the University of Munich. It comprises five chapters addressing one or more aspects of international trade and...

This paper considers labor market adjustments following a large import shock in the German clothing industry caused by the phasing out of the Multi-Fibre Arrangement. Using the German shoe industry as a control group and administrative data, we study adjustments on the individual and firm level...

There is increasing evidence that the interaction between shocks and labour market institutions is crucial to understanding the dynamics of employment. In this paper, we show that the inclusion of labour adjustment costs in a trade model affects the impact of exchange rate movements on...

We explore the far-reaching implications of replacing current unemployment benefit (UB) systems by an unemployment accounts (UA) system. Under the UA system, employed people are required to make ongoing contributions to their UAs and the balances in these accounts are available to them during...

The fear of massive job losses has prompted a fast-growing literature on offshoring and its impact on employment in advanced economies. This paper examines the situation for Belgium. It improves the offshoring intensity measure by computing a volume measure of the share of imported intermediates...

We explore the far-reaching implications of replacing current unemployment benefit (UB) systems by an unemployment accounts (UA) system. Under the UA system, employed people are required to make ongoing contributions to their UAs and the balances in these accounts are available to them during...
