Requirements

  • Participation in class discussions.
  • Problem sets focused on empirical methods.
  • Replication exercise and research proposal.

Importance of Development Economics

  • Development economics is relevant for economists across all fields.
  • Examines how the poorest live their lives and the implications of income differences.

Key Measurements

  • Gross National Income (GNI) vs. GDP:
    • GNI includes income of residents regardless of location, while GDP measures production within a country’s borders.
    • GNI may provide a better measure of living standards.

Purchasing Power Parity (PPP)

  • Adjustment that accounts for price differences across countries.
  • Difficulties in measuring PPP due to differences in consumption baskets and quality of goods.
  • Political implications of poverty measurements and how they affect international assistance.

Income Disparities

  • Richest countries (e.g., Macau, Luxembourg, Norway) and poorest countries (e.g., Burundi) show stark contrasts in GNI per capita.
  • Mortality rates correlate with income levels; understanding income differences is crucial for development policies.

COVID-19 Impact on Development

  • Discrepancies in vaccination rates and fiscal responses between rich and poor countries during the pandemic.
  • Rich countries spent about 20% of GDP on fiscal stimulus; poorest countries spent around 2%.
  • The long-term effects of COVID-19 on poverty and economic growth are uncertain.

Historical Context and Improvement in Welfare

  • Education and health improvements have been noted in many developing countries, leading to reduced mortality rates and increased schooling years.
  • Pre-COVID projections indicated a decline in global poverty rates, but the pandemic has reversed this trend.

Measuring Poverty

  • The international poverty line is set at $1.90 (PPP).
  • The COVID-19 crisis has disrupted data collection, making it difficult to measure current poverty levels accurately.

Causes of Economic Growth Differences

  • Historical and geographical factors play a role, but internal policies and governance are critical for development.
  • Increasing awareness of the need for effective policy-making in health and education.

Poverty Traps

  • The concept of poverty traps suggests that poor individuals may remain stuck in poverty without significant external help.
  • The lecture highlights the role of effective transfers and asset-building programs in breaking the cycle of poverty.

Conclusion and Future Directions

  • The course aims to explore various economic problems specific to poor countries and discuss policies that could address these issues.
  • There will be a focus on understanding the internal factors affecting growth and poverty, and the potential for improving these conditions through informed policy decisions.
