Michael Cohen in this lecture illustrates data about economic growth that demonstrate how cities act as engines of national economic development. In 2008, for the first time in human history, half the world’s population lived in urban areas. Due to agglomeration economies, approximately 80 percent from global GDP is coming out of urban-based economic activities; 600 urban centers generate about 60 percent of global GDP.

Yet, without the right focus, agglomeration economies can have deleterious negative externalities, such as harmful environmental effects, urban poverty, and intra-urban inequalities. In addition, the lecture addresses the issue of climate change, which represents a major threat to cities.

The city is the space of opportunity for growth. Cities can also serve as a remedy in periods of economic crisis and help sustain employment. Since 2009, G-20 discussions have reduced their attention to urban employment even though most of the “demand” which governments wish to stimulate exists within cities. The stimulus package after the Global Crisis in 2008 did not focus enough on urban issues. This resulted in reduced investments into the urban arena, which in turn increased urban poverty and unemployment, worsened the distribution of income, and lead to growing squatter settlements.This lecture suggests that the productive side of the city needs more attention in urban planning.

Propositions for addressing the issue:

  1. Statistical trends indicate the large share of urban contributions to national economic development. This confirms the assumption that cities are opportunities for growth and sustainable development.
  2. Cities can serve as remedies in times of global crisis.
  3. A neglect of this trend leads to reduced investments in urban areas. This in turn increases negative externalities from agglomeration economies, which can have adverse effects on the entire country.
  4. Almost 50 percent of all cities are already dealing with the effects of climate change. Especially urban flooding causes a serious and growing development challenge.
  5. Urban governments, in coalition with various actors, need to produce a broader, comparative, empirical framework that can examine more deeply what is happening to capital and labor in relation to urban growth.
  6. Land and land policies are central to this process.
