Economic globalization causes an increasing international fragmentation (disintegration) of value-added-chains, whereby firms outsource components of production to foreign markets. There is a high level of concern about unwelcome distributional effects. This paper provides a theoretical...

International fragmentation, or outsourcing, is often referred to as a distinctly novel feature in today's global economy. First observed in the US-Mexican context, the phenomenon is increasingly catching policy makers' attention also in Europe. As barriers between east and west are...

A distinctive feature of the present wave of economic globalization is that the principle of world-wide arbitrage is increasingly applied to individual components of value added chains, rather than final goods. The result is a phenomenon called outsourcing, or international fragmentation....

I develop a generalized factor price frontier which incorporates endogenous adjustment of international fragmentation in multistage production, allowing for a continuum of stages. This allows us to address fragmentation, not only as an exogenous event, but also as an integral part of endogenous...

We present a model, in which a small industrialised economy outsources part of its production into a small foreign country which is well endowed with low-skilled labour. We analyse under which conditions sinking trade costs stimulate outsourcing activities, thereby increasing the wage dispersion...

We analyze a firm that produces a final good from multiple intermediates, each of which can be sourced domestically or from a low-wage country. Offshoring an intermediate is only profitable when it has matured sufficiently and the savings in production cost outweigh the underinvestment due to...

We develop a theory of a firm in an incomplete contracts environment which decides on the complexity, the organization, and the global scale of its production process. Specifically, the firm decides i) how many intermediate inputs are simultaneously combined to a final product, ii) if the...
