South America - Region

America is split in two by South America and North America. South America consists more of countries whereas North America consists of mainly states and Canada (some consider Mexico has part of North America as well). You can find a list of Southern American countries in the table below and where they are situated in the map which directly proceeds. The Southern Cone countries are Argentina, Chile, and Uruguay, which are the most prosperous countries in South America.

Mobile telephony in South America had a somewhat late start compared with the rest of the world, and only really took off in 1999-2000, when the major mobile markets in the region experienced an explosive growth. Prepaid services played an important role the sector’s success, as they made cell phones available to millions of low-income users.

HHI: Evolution, LA selected Countries:




As the graph above shows, in the years 2001 - 2005 the revolution of the HHI in South America has been uneven across countries. In Brazil, Paraguay and Venezuela, the level of concentration has diminished between 2001 and 2005. Brazil has the lowest concentration level in the region while in Argentina and Chile the HHI increased probably due to the acquisition of Bell South's by Telefonica Moviles in 2005.




Diffusion of Analogue and Digital Mobile Telecommunications in South America


In South America there was a rapid migration from analogue technologies to digital. It was predicted that by 2008 all of the networks would be digital (see the graph above). Empirical studies found that standardization does not promote price competition whilst other policy instruments such as number portability are more effective in inducing mobile diffusion.





As the graph above shows, after 1998, while teledensity tends to stagnate in most countries, mobile telephony begins to grow at two digit ratios. The average annual growth of mobile telephony users during the 2000 - 2005 period was 20.3% in the region, while froth in the case of telephony was only 0.4%
