There are only few estimates of the returns on contributions to the German public pension System (GPPS). Those that are published ränge between nominal rates of future returns between about 4,5 % and 48 %, indicating that GPPS treats different groups of people differently. The authors develop a...

This paper is concerned with establishing the data base that is necessary to analyse the double bürden argument which has been used to reject a sweeping reform of the German old-age pension System. We show that this argument does not hold if the existing pay-as-you-go system were to be replaced...

We contribute to the nascent literature on the heterogeneity of multinational enterprises (MNEs) and the relevance of firm characteristics for analyzing the determinants of outward foreign direct investment (FDI). The focus is on the role of firm-level heterogeneity when MNEs decide on the share...

We present a two-step approach of assessing whether major donors of foreign aid have met recent demands for less proliferated and better coordinated aid efforts. First, we calculate Theil indices revealing the concentration of each donor's aid on recipient countries and specific aid sectors....

This paper estimates the aggregate productivity effects of Marshallian externalities generated by foreign direct investments (FDI) in the US. In contrast to earlier work, this paper puts special emphasis on controlling for Marshallian externalities and other intra- and inter-regional spillovers...

Previous literature largely ignores the heterogeneity of aid channels used by each single donor country. We estimate Tobit models to assess the relative importance of recipient need, recipient merit and self-interest of donors for various channels of official and private German aid across a...

There is a startling gap between, allegedly, globalization-induced changes in international competition for foreign direct investment (FDI) and recent empirical evidence on the relative importance of determinants of FDI in developing countries. We show that surprisingly little has changed since...

It is widely believed that the determinants of foreign direct investment have changed fundamentally in the process of globalization. We apply correlation and regression analyses in order to test this proposition for German direct investments in developing and transition economies. Indications...

Conclusive evidence supporting the widely held view that developing countries should draw on foreign direct investment (FDI) to spur economic development is surprisingly hard to come by. We raise the proposition that results on the growth impact of FDI are ambiguous because highly aggregated FDI...
