Three Views on Aid and Growth View #1: No relationship, or a negative relationship • Boone, Rajan & Subramanian • Almost always assumes a linear relationship
View #2: Conditional Relationship • Depends on recipients (good governance; strong policies) • Burnside & Dollar, Collier & Dehn • Interaction term, assumes linear relationship • Fragile (Easterly, Levine, & Roodman) • Conditional relationship could also depend on the characteristics of donors, but not well researched.
View #3: Positive relationship, on average, with diminishing returns • Hansen & Tarp; Hajimichael, et. al, 1995; Durbarry et al, 1998; Lensink and White, 2001; and Dalgaard, et al, 2004 • Diminishing returns • Less well known
“Counting Chickens” • Key characteristics: Diminishing returns and disaggregation • Three Categories of Aid • Focus on “early-impact” aid with most direct plausible connections to growth, with diminishing returns

Connections to other strands of the literature: What do the results look like with diminishing returns and disaggregation? • Burnside & Dollar • Hansen and Tarp • Rajan & Subramanian
Rajan and Subramanian: No independent variable in R&S is consistently associated with growth (not just aid)
R&S mostly impose linearity • 71 regression results; 65 test linear relationship. No surprise these results are weak. • 6 non-linear, all positive coefficients (some but not all statistically significant) • Only one nonlinear with a disaggregated aid variable. Positive and significant, supporting the basic idea of “Chickens.”
