According to the aim of Latvia's government to join the European Union, there was a possibility to obtain financial instruments provided by the European Union starting from 2000. It is a great opportunity for the country economy to develop open market and entrepreneurship in Latvia in different sectors. In compliance with a possibility of regional development to diminish regional disparities these instruments provide the regional policy of the European Union. Three periods may be displayed for Latvia's economy: the first period - 2000-2006, the second period - 2004-2006 (2008), and the third period - 2007-2013. It has to be mentioned that Latvia's government has to co-finance all European Union financial instruments as a part of this support. Recently a lot of macroeconomic indicators have rapidly changed, like the employment rate, the GDP growth and amount per capita as well as the increase of average salaries in the country. These changes have a strong impact on population's welfare that should be the aim of every government. Theoretical information on the three EU planning periods in Latvia is compared in the article.
