Declining Inequality in LA: How Much? Inequality in most Latin
American countries (13 out of 17) has declined (roughly 1% a year) between (circa) 2000 and (circa) 2009
Decline continued through the global financial crisis in 2009
Inequality declined in LA while it rose in other regions 8

Declining Inequality in LA: Since When?
In three countries, during second half of 1990s: Mexico, Brazil and Chile
In six, started in 2002-2003: Argentina, Bolivia, El Salvador, Paraguay, Panama and Peru
In others, although there are fluctuations, inequality between 2000 and 2009 increased: Costa Rica, Honduras and Uruguay 11

The decline in inequality has been widespread
Fast growing countries (Chile and Peru), slow growing countries (Brazil and Mexico) and countries recovering from crisis (Argentina and Venezuela)
Persistently high inequality countries (Brazil) and normally low inequality countries (Argentina)
Countries with left “populist” governments (Argentina), left social-democratic governments (e.g., Brazil, Chile) and center/center-right governments (e.g., Mexico and Peru)

Why has inequality declined in Latin America? Are there factors in common?
In-depth analysis in four countries: Argentina (Gasparini and Cruces) (urban; 2/3 of pop)
Brazil (Barros, Carvalho, Mendoca & Franco) Mexico (Esquivel, Lustig and Scott) Peru (Jaramillo & Saavedra)

Decline is robust
Statistically significant and significant in terms of order of magnitude
Lorenz dominance (unambiguous decline independently of choice of inequality measure)
Robust to income concept (e.g., monetary vs. total—which includes nonmonetary elements--)

Proximate and fundamental determinants of changes in inequality
There are many different factors that affect the distribution of income over time: “… the evolution of the distribution of income is the result of many different effects—some of them quite large—which may offset one another in whole or in part.” (Bourguignon et al., 2005)
Useful framework: to consider the ‘proximate’ factors that affect the distribution of income at the individual and household level:1. Distribution of assets and personal characteristics2. Return to assets and characteristics3. Utilization of assets and characteristics4. Transfers (private and public)5. Socio-demographic factors 27

Decomposition results (Alejo et al., 2009):
Demographics: Changes in the ratio of adults per household were equalizing, albeit the orders of magnitude were generally smaller except for Peru.

![Page 30: Beijing, China, February 21, 2012 ( via Skype)](https://reader036.vdocuments.us/reader036/viewer/2022062422/568130a8550346895d96aeac/html5/thumbnails/30.jpg)
Decomposition results (Alejo et al., 2009):
Labor force participation: With the exception of Peru, changes in labor force participation (the proportion of working adults) were equalizing.
This effect was stronger in Argentina. 30
![Page 31: Beijing, China, February 21, 2012 ( via Skype)](https://reader036.vdocuments.us/reader036/viewer/2022062422/568130a8550346895d96aeac/html5/thumbnails/31.jpg)
Decomposition results (Alejo et al., 2009):
Labor income (Earnings): In Argentina, Brazil, and Mexico between 44% and 65% of the decline in overall inequality is due to a reduction in earnings per working adult inequality.
In Peru, however, changes in earnings inequality were unequalizing at the household level but not at the individual workers’ level.
=> decline in skill premium a driving force

Decomposition results (Alejo et al., 2009):
Non-labor income: Changes in the distribution of non-labor income were equalizing;
the contribution of this factor was quite high in Brazil and Peru (45% and 90%, respectively).
=> more generous and progressive transfers, an important factor
34

36
![Page 37: Beijing, China, February 21, 2012 ( via Skype)](https://reader036.vdocuments.us/reader036/viewer/2022062422/568130a8550346895d96aeac/html5/thumbnails/37.jpg)
Why has the skill premium declined?
Increase in relative supply of high-skilled workers
Decline in relative demand for skilled labor petered out
Institutional factors that compress the wage structure: minimum wages and unionization 37
![Page 38: Beijing, China, February 21, 2012 ( via Skype)](https://reader036.vdocuments.us/reader036/viewer/2022062422/568130a8550346895d96aeac/html5/thumbnails/38.jpg)

Other factors specific to country
Argentina: Pro-union government stance and by the impetus to low-skill intensive sectors from devaluation. Increase in minimum wages.
Brazil: Decline in spatial labor market segmentation and increase in minimum wage.
Mexico: The expansion of post-NAFTA maquiladoras.
40
![Page 41: Beijing, China, February 21, 2012 ( via Skype)](https://reader036.vdocuments.us/reader036/viewer/2022062422/568130a8550346895d96aeac/html5/thumbnails/41.jpg)
Why has inequality in non-labor incomes declined?
Government transfers became more progressive and generous for the poor:▪ In Argentina, the safety net program Jefes y
Jefas de Hogar.▪ In Brazil and Mexico, large-scale conditional
cash transfers => can account for between 10 and 20 percent of reduction in overall inequality. An effective redistributive machine because they cost around .5% of GDP.
▪ In Peru, in-kind transfers for food programs and health. Also access to basic infrastructure for the poor rose.. 41
![Page 42: Beijing, China, February 21, 2012 ( via Skype)](https://reader036.vdocuments.us/reader036/viewer/2022062422/568130a8550346895d96aeac/html5/thumbnails/42.jpg)
Conclusions
In the race between skill-biased technological change and educational upgrading, in the last ten years the latter has taken the lead (Tinbergen’s hypothesis)
Perhaps as a consequence of democratization and political competition, government (cash and in-kind) transfers have become more generous and targeted to the poor
42
![Page 43: Beijing, China, February 21, 2012 ( via Skype)](https://reader036.vdocuments.us/reader036/viewer/2022062422/568130a8550346895d96aeac/html5/thumbnails/43.jpg)
Is Inequality Likely to Continue to Fall?
Despite the observed progress, inequality continues to be very high and the bulk of government spending is not progressive enough.
43
![Page 44: Beijing, China, February 21, 2012 ( via Skype)](https://reader036.vdocuments.us/reader036/viewer/2022062422/568130a8550346895d96aeac/html5/thumbnails/44.jpg)
Is Inequality Likely to Continue to Fall?
The decline in inequality resulting from the educational upgrading of the population will eventually hit the ‘access to tertiary education barrier’ which is much more difficult to overcome: inequality in quality and ‘opportunity cost’ are high and costly to address.
=> United States experience should serve as warning (Goldin and Katz, 2008)
