This study explores sex differences in language and socio-emotional skills on children 7 months to 6 years old in Latin-America. Females had a significant advantage in both dimensions. To our knowledge, this is the first study to document sex differences in these dimensions at a very young age....

Host countries have implemented permanent and guest-worker (GW) immigration programs in recent decades, while the temporary movement of service providers under Mode IV of the GATS is one of the issues being negotiated at the Doha Round of the WTO. Though decisions on what programs to adopt have...

Census data show that since 1980 low-skill workers in the United States have been increasingly employed in the provision of non-tradeable time-intensive services - such as food preparation and cleaning - that can be broadly thought as substitutes of home production activities. Meanwhile the wage...

Immigration continues to be on the forefront of the policy debate on both sides of the Atlantic. A number of reforms of permanent and guest-worker (GW) immigration programs are being considered, and the temporary movement of service providers under Mode IV (GATS) is being negotiated at the Doha...
