This report investigates Egypt's regional economic growth, explores the causes for geographically unbalanced development, and proposes policy options to make unbalanced growth compatible with inclusive development. Regional disparities in income and consumption may be attributed to differences in natural endowments and geographical location, but unbalanced growth is mostly due to economies of scale, spillover effects, and the lower transaction costs that result from agglomeration. In Egypt, despite rapid progress in most welfare indicators in lagging regions, there are still substantial gaps in consumption and opportunities between growth poles and the rest of the country. Adopting integration as a development platform is not simple because spatial disparities are spanned in three dimensions: urban/rural dichotomies, the upper Egypt/lower Egypt duality, and the differences between large metropolises and the rest of the country. This typology of instruments underlies the menu of options presented in this report as the basis of domestic spatial integration as a development platform to achieve more balanced and equitable development without sacrificing growth. This report first identifies the gaps in consumption and in opportunities, showing the stark contrasts between regions and how they evolve through time. It then explores the causes of the gaps, revealing a multiplicity of factors and exposing the complexity of the problem. Finally, the bulk of the report presents the policy options to address the integration challenges.
