Migrants, Ancestors, and Investments

Migrants, Ancestors, and Foreign Investments∗

We use 130 years of data on historical migrations to the United States to show a causal effect of the ancestry composition of US counties on foreign direct investment (FDI) sent and received by local firms. To isolate the causal effect of ancestry on FDI, we build a simple reduced-form model of migrations: migrations from a foreign country to a US county at a given time depend on (i) a push fac...

Genetic and Genealogical Ancestors

15.4.2011 The genealogical ancestors to an individual are the the individuals that can be reached by a string of operators mother/father to that individual, like motherfatherfather. Within that set are the individuals, that has genetic material that was transmitted to the present individual. Genetic ancestry is in general given more attention as that is a component in genetic analysis and mapp...

Aquarboreal ancestors?

According to biomolecular data, the great apes split into Asian pongids (orang-utan) and African hominids (gorillas, chimpanzees and humans) 18–12 million years ago (Mya) and hominids split into gorillas and humans–chimpanzees 10–6 Mya. Fossils with pongid features appear in Eurasia after c. 15 Mya, and fossils with hominid fossils appear in Africa after c.10 Mya. Instead of the traditional sav...

S17-05 Embryos and ancestors

related homeobox 1 gene, Prrx1, are up-regulated in the autopods of the bat wing compared to the bat hindlimb and mouse forelimb. Changes in the mRNA transcript abundance of several genes involved in retinoic acid (RA) synthesis, degradation and signaling were consistent with the down-regulation of the RA signaling pathway in the developing bat wing autopod. Signal from a microarray probe targe...
