Can immigration point systems identify desirable immigrants? This column investigates the lessons of 19th-century migration from then-poor Denmark to the US. By 1890, Denmark had developed into a world-leading dairy producer. It finds that areas in the US with many Danes before the transformation of Danish agriculture benefited from significant knowledge transfers thereafter, and specialised in high-tech dairying. This provides a cautionary tale for those arguing that desirable migrants can be identified ex ante.

The H-1B programme allows high-skilled foreign nationals to temporarily work in the US. This column explores how changes in H-1B policy affect the quantity and characteristics of workers entering the country through the programme. The results suggest that reductions in the cap on H-1B workers have particularly hindered the employment of the highest ability foreign-born workers and have not led firms to hire more Americans.

This column shows that female immigrants’ labour supply reflects female labour supply in their country of origin. As more immigrant women arrive from countries with more traditional gender norms, the US female labour force participation rate may fall.
