    Study Notes

    Population Growth and Urbanization

    • Rapid population growth drives urbanization, with people seeking opportunities in cities.
    • Demand for essential infrastructure like transportation, housing, water, and sanitation increases in cities.
    • Cities require sustainable infrastructure to support a growing population while minimizing ecological impact.
    • The world's population is projected to reach 9.8 billion by 2050.
    • Eastern Europe's population is expected to decrease by 10% by 2050, while Africa is projected to contribute around 60% of global population growth during this period.
    • Sub-Saharan Africa is the youngest region, with 40% of its population under 15.
    • Western Europe and Southern Europe are the oldest regions, with 21% of the population aged 65 and older.

    Aging Populations in Developed Countries

    • Many developed nations are facing challenges related to aging populations due to declining birth rates and longer life expectancies.
    • These demographic shifts lead to labor shortages, impacting productivity and economic growth.
    • Aging populations result in increased healthcare and social security costs, straining state finances.
    • Policies promoting workforce participation, retraining programs, and initiatives to address demographic gaps are crucial.
    • The United States has the highest number of immigrants, with over 52 million, followed by Germany with 16 million.
    • Immigration trends can place a strain on public services and resources, requiring effective policies for management.
    • High dependency ratios, particularly in wealthy countries with aging populations, can present economic challenges.

    Market Failure

    • Market failure occurs when the production or consumption of goods and services generates external costs or benefits not reflected in market prices.
    • Externalities, like pollution, result in costs not borne by producers or consumers.
    • Public goods, which are non-excludable and non-rivalrous, cannot be efficiently provided by private markets.
    • Information asymmetries, where one party has more information than the other, lead to suboptimal decisions.
    • Monopolies and market power stifle competition and result in higher prices.
    • These factors prevent markets from achieving optimal outcomes, necessitating government intervention to address inefficiencies.
