The Solow model again Framework to justify aid. Let s go back to the Solow model The Aid Debate February 25, 2010 28

d+n sf(k)/k k* k In this model there is a unique equilibrium The Aid Debate February 25, 2010 29

Multiple equilibria Several factors can create multiple equilibria in this model. 1. Variable saving rate Suppose that s = s(y, r) s is the saving rate, y is income and r is the interest rate (MPK) Thus, s = s(k) and it s not longer a constant. This leads to a new curve The Aid Debate February 25, 2010 30

n+d s(k)f(k)/k k* k*** k** capital Economies are identical except for their initial conditions. There is no global equilibrium. There are two local ones. The Aid Debate February 25, 2010 31

2. Non-convexities Assume that s is fixed, just like in the original Solow model. Non-convexities arise when the APK is nonlinear due to technical reasons. Or when there are two technologies available.... but firms can only use one at a time. In both cases the s f(k) k will follow the pattern shown above. The Aid Debate February 25, 2010 32

In his calculation, Quah uses per capita GDP relative to the world average over the period 1962 to 1984 in a sample of 118 countries. Relative income is discretized into state space S := {1, 2, 3, 4, 5} consisting of 5 bins, with states corresponding to values for relative GDP of 0 0.25, 0.25 0.5, 0.5 1, 1 2 and 2 respectively. The transition matrix P = (p ij ) is computed by setting p ij equal to the fraction of times that a country, finding itself in state i, makes the transition to state j the next year. The data is assumed to be stationary, so that all of the transitions can be pooled when calculating transition probabilities. The result of this calculation [Quah (1993, p. 431)] is 0.97 0.03 0.00 0.00 0.00 0.05 0.92 0.03 0.00 0.00 P = 0.00 0.04 0.92 0.04 0.00 0.00 0.00 0.04 0.94 0.02. 0.00 0.00 0.00 0.01 0.99 Azariadis & Stachurski (2005) Handbook of Economic Growth, Chapter 5: Poverty Traps The Aid Debate February 25, 2010 35

Burnside and Dollar, 2002 Is the effect of aid on growth conditional of economic policies? Do donor governments and agencies allocate more aid to countries with good policies? These two are important question and BD (2002) try to answer them both. The Aid Debate February 25, 2010 41

Empirical strategy To answer the first question, the authors will estimate the following equation g it = α + βaid it + θpolicy it + γx it + η t + ϵ it (1) g it is the percapita growth rate of country i in period t. AID is AID GDP Policy and index of good policies (budget surplus, inflation and openness). X it are controlled variables. g it = α+βaid it +θpolicy it +γ(aid it Policy it )+γx it +η t +ϵ it (2) Question: can we obtained unbiased parameters for β? What about γ? The Aid Debate February 25, 2010 42

Data sources New data from the World Bank on aid. Sample of 56 countries and six four-year time periods from 1970-73 to 1990-93. There are 21 African countries. All major aid recipients in other regions are included. They also concentrate on lower income countries: those with GDP percapita lower than $1,900 in 1970. The sample is then reduced to 40 countries. The Aid Debate February 25, 2010 43

Empirical strategy The authors recognize the endogeneity of aid. Two questions for you: How can aid be endogenous? How could you solve this problem? The Aid Debate February 25, 2010 44

Empirical strategy (II) The authors will use instrumental variables. The key idea is that AID is endogenous. They also created an index for good policies. Policy = 1.28+6.85 Budget surplus 1.40 Inflation+2.16 Openness. However, they will treat the policy index as exogenous. Do you agree? The Aid Debate February 25, 2010 45
