The contributors, including many of the world’s most respected economic development analysts, focus on the ongoing debate over which paths to development truly maximize results. Should we emphasize a big-picture approach—focusing on the role of institutions, macroeconomic policies, growth strategies, and other country-level factors? Or is a more grassroots approach the way to go, with the focus on particular microeconomic interventions such as conditional cash transfers, bed nets, and other microlevel improvements in service delivery on the ground? The book attempts to find a consensus on which approach is likely to be more effective.
