This study explores the effect of parallel imports (PIs) when the producer may discriminate repair and maintenance services against PI units. This service discrimination weakens intra-brand competition and reduces the degree of price convergence between countries. If the producer makes costly...

Does an increase in imported inputs raise exports? We provide empirical evidence on the direct and indirect channels via which importing more varieties of intermediate inputs increases export scope: (i) imported inputs may enhance productivity and thereby help the firm to overcome export fixed...

Over the last decade, European Union members have experienced a dramatic increase in imports. This increase was accompanied by a strong growth in the number of imported goods and trading partners, indicating positive welfare gains for consumers via an extended set of consumption possibilities,...

In times of increasing oil prices and a weak dollar, European companies that focus their business on the US market may find themselves in a weak position. While many businesses can hedge this kind of risk by relocating production to the US, or employing financial remedies, these strategies may...
