Selection issues: who migrates?
• Immigrant mix by origin: rising ethnic diversity
• Quality: falling skill and schooling relative to native-born
• Age: high labor participation and low dependency rates relative to native-born (stable)
• Gender: bias favoring males (stable)
Rising ethnic diversity (by source) and debate about declining immigrant quality

Four Stylized Quality Facts
• Native-born ‘quality’ (= human capital per person) rose across the late 19th century
• Foreign-born ‘quality’ fell across the late 19th century
• Native-born ‘quality’ rose across the late 20th century
• Foreign-born ‘quality’ rose far less across the late 20th century. Ergo, relative quality fell.
US native-born ‘quality’ rose 1870-1930

However, …
We clearly need a better model!

Global Century with unrestricted migration

Variable definitions: MigRate = gross emigration rate per thousand population per decade to all foreign destinations; LnWRatio = log of the ratio of purchasing power parity adjusted wage rates, source country to a weighted average of destination countries; LnRWage = log of source country purchasing power parity adjusted real wage; LagBirth = source country birth rate lagged 20 years; Migstock = stock of previous immigrants in destination countries at beginning of decade per thousand of source country population; Dum = dummy for Belgium, Italy, Portugal and Spain. Method: Pooled OLS regression on 48 country/decade-average observations. Source: Variant of Hatton and Williamson (1998: Table 3.3, column 4, p. 39).

Does the same model work today?
Yes.
It works for African emigration.
It works for US immigration.
And why not? Even though immigration policy is far more restrictive today, the fundamentals driving mass migration are also far bigger.

World Wage Convergence, Host Country Crowding Out, and Inequality
The Welfare State, Fiscal Effects and Accommodating Adjustment in Other Markets
Culture, Language, Disease and Violence
Road Map for World Wage Convergence, Host Country Crowding Out, and Inequality
The total impact of mass migration on world wages has four component parts (cet. par.):[1] the wage gap between countries falls (e.g.
convergence between countries)[2] host country wages fall (crowding out and
supply glut → more host country inequality)[3] sending country wages rise (crowding in and
rising supply scarcity → less sending country inequality)
[4] The migrants gain the most by far (→ less world inequality)
Remember, ceteris paribus!
Magnitudes will depend on the:
Size of the migration
Size of the sending and receiving countries
Other (domestic) determinants of wages, independent of the migration

Qualifying the convergence bottom line
• Let capital chase labor so that r=f(k) is constant. What then? (Remember: the pre-1913 and post-1970 years are ones of global capital markets.)

Qualifying the convergence bottom line
• By letting capital chase labor so that r=f(k) is constant, the amount of convergence explained by mass migration drops to 70%, with 30% left for other forces. Mass migration still played a huge role, …
if only in the Atlantic economy (= North).
• That is, world labor markets between the South and the North were segmented.
Give me two reasons why you would NOT expect the same result today.
• Remember ceteris paribus!• Remember we are talking about raw or
unskilled labor![1] The relative size of the migrations are
less today (especially sending regions). After all, immigration is restricted everywhere.
[2] The other (independent) influences are much bigger today.

Williamson’s favorite example where immigrants crowded-out native-born
World War I and US immigrant restrictions lowered foreign immigration big time, and crowded in black Americans from the US south. The resulting “Great Migration” south to north had a spectacular impact on 20th century US social history.
An example from the presentImmigration and Internal Migration: UK Regions by Year, 1982-2000
NetMigRt = 0.43 NetImRt-1 + 0.44 LogVacst – 0.13 LogUnRt + 2.78 LogEarnt-1 (2.1) (2.3) (0.3) (2.4) – 0.83 LogHsePt + 0.94 LogHsePt; Adj R2 = 0.92 (2.2) (1.7) Note: ‘t’ statistics in parentheses. Sample: Balanced panel of region/years. The regions are: Greater London, Rest of the Southeast, East Anglia, East Midlands, West Midlands and South West. Variable definitions: NetMigR = net migration rate into the region from elsewhere in the UK, per 1000 of the region’s population; NetImR = net immigration from abroad of foreign citizens per 1000 of the region’s population; LogVacs = log of the region’s vacancy inflow rate; LogUnR = Log of the region’s unemployment rate; LogEarn = Log average earnings of full time equivalent workers in the region; LogHseP = log of average house price in the region; LogHseP = change in log house price. Method: OLS regression; fixed region effects and year dummies included but not reported. Note that, because year dummies are included, this is equivalent to defining the logs of vacancies, unemployment, lagged earnings and house prices as log ratios to the UK mean.
Demand curves ARE downward sloping to the right
• If crowding out is so obvious in history, how come modern economists like David Card don’t believe it?
• The first to challenge the Mariel boat lift results (Altonji and Card 1991; Card 1991, 2001) were Borjas, Freeman and Katz (1997).
• Now we know that a 10% labor supply increase (decrease) lowers (raises) wages by 3-4% in Canada, the US and Mexico!

The Welfare State, Fiscal Effects and Accommodating Adjustment in Other Markets
Culture, Language, Disease and Violence
Road Map
• Violence: Has (young male adult) migration influenced levels of violence in Mexican municipalities?
• Language: Does migration destroy languages?
• Disease: How have the 15th c. Colombian migration connection and the 20th c. African AIDS migration connection impacted the host countries?
• Culture: Does immigration destroy mainstream host country culture?
Violence: Migration, Sex Ratios and Crime
• Two facts of life: Testosterone-driven young men are much more violent than young women, and the scarcity of young women (and glut of young men) makes matters even worse as competition for partners intensifies.
• A fact of migration: Migration self selects young males.
• Hypothesis: Recent Mexican migration should have reduced violent crime in high-exit Mexican municipalities and increased it in high-entrance US municipalities.
• Did it?

(October 2006).
Migration:Language Loss or Gain?
• Source: David Clingingsmith, “Bilingualism, Language Shift, and Industrialization in India 1931-1961,” Economics Department, Harvard (November 2006).
• 1500: About 10,000 languages spoken.• 2000: About 6,700 languages spoken.• 2100: Estimated 3,350 languages spoken (with
the vast majority speaking English, Spanish, Chinese or Hindi).
Why the loss of language?
Individual investment: Costs and benefits of acquiring bilingualism to migrating parents; costs and benefits of transferring bilingualism to kids
Market determinants of benefits: – Manufacturing (urban) vs farming (rural)– More generally, trade and GDP growth foster
specialization by location– Both foster migration and language loss– This explains most of the language loss in India 1931-
1961 (where 180 languages are still spoken).
Disease and Death: The Columbian Connection
(from Livi-Bacci 2006)• 1492-1574: In 1574, Hispanic American
population was 8-10 million (80 years after Columbus; 50 years after Cortés destroyed the Aztec capital; 40 years after the Incan emperor was assassinated by Pizarro). In 1492, “new” population estimates are 50.1-90.4 million (80-91% loss).
• 1568-1595: Central Mexican population had fallen from 2.7 to 1.4 million (48% loss).
• 1570-1600: Peruvian population fell from1.3 to 0.9 million (31% loss).
