Study Notes

Population and Demographics in the EU

Germany had the highest population in the EU27 as of January 1st, 2022.
A Gini coefficient measures income inequality; a value of 0 indicates perfect equality.
Hungary recorded the highest increase in the Gini coefficient from 2012 to 2018.
The replacement level for the total fertility rate in developed countries is approximately 2.1.

Population Changes and Trends

Bulgaria and Latvia experienced the largest population percentage decreases from 2011 to 2021.
Net migration, as defined by the World Bank, refers to the difference between the number of immigrants and emigrants.
The bulge in the middle of the EU-27 population pyramid for 2019 is attributed to the post-war baby boom generation.
Lengthening of the bars for the upper age group in the EU-27 population pyramid for 2050 indicates an expected increase in the elderly population.

Economic Implications and Labor Markets

Italy’s population pyramid is more similar to that of the EU than to the world's average.
Economic impacts of migration can include labor market adjustments, GDP growth, and changes in income distribution.
The collective supply curve reflects the total supply from all producers, while the individual supply curve is from one producer.
Severe labor market rigidities can lead to increased unemployment and heightened inequality, especially in the context of trade integration.

Income Inequality and Employment

Sigma-convergence is a condition for reducing income inequality across economies, typically indicated by lower disparities in income levels.
Measuring sigma-convergence across EU27 member states reveals a persistence of income inequality.
The percentage of foreign citizens in the EU is increasing, with implications for labor markets and social dynamics.

Unemployment and Emigration

Spain has the highest unemployment rate among EU countries.
Opportunity cost represents the benefits lost from not choosing the next best alternative.
The main determinant of emigration is often the search for better economic opportunities.

Ageing Population

An ageing population is characterized by an increasing median age and a higher proportion of older individuals.
The implications of an ageing population include increased healthcare costs and strains on pension systems.
The age dependency ratio is the ratio of people typically not in the labor force (young and old) to those who are.
Projected old-age dependency ratio in the EU is expected to reach approximately 50% by January 1, 2050.

Effects of Emigration and Immigration

Emigration affects wages and efficiency by potentially raising the wage level due to decreased labor supply and enhancing efficiency through the migration of skilled labor.
Negative externalities of immigration can include increased pressure on public services and potential social tensions.
Redistributive effects of immigration on public finances in host countries may include changes in tax revenue and public service expenditure adjustments.
