Purpose of study: To explore the role of land inequality in affecting how economic growth occurs To explore how land inequality affects labor productivity in agriculture and non-farm sectors
Purpose of study: To explore the role of land inequality in affecting how economic growth occurs (in areas that are still primarily agrarian) To explore how land inequality affects labor productivity in agriculture and non-farm sectors Main hypothesis: the initial distribution of assets affect the rate of economic growth it also affects the poverty-reducing effects of the growth that does occur
Theory Why should land concentration affect the link between ag growth and poverty reduction? Concept of “multiplier effects”
Applied evidence Ravallion and Datt (2002) the initial percentage of landless households significantly affected the elasticity of poverty to non-farm output in India. Vollrath (2007) Rate of agricultural productivity growth inversely related to the gini coefficient of landholdings Gugerty and Timmer (1999) (n=69 countries); in countries with an initial “good” distribution of assets, both agricultural and non-agricultural growth benefitted the poorest households. In countries with a “bad” distribution of assets, economic growth was skewed toward wealthier households

Methods Dependent variables: (household-level) agricultural output per family adult labor time on farm (15-64 yrs) non-farm output per family adult labor time in non-farm activities total household income per family adult labor
Methods Estimated reduced form models of labor productivity Particular interest in the coefficient of land inequality measures at district- level Gini coefficient Measure of skewness Gugerty and Timmer’s measure Y it = f ( X it, C it, LandIneq jt-1 ) + e it Pooled OLS with Mundlak-Chamberlin device / fixed effects, applied to panel data
Data Nationwide panel data sets: Kenya (1997, 2000, 2004, 2007, 2010) (n=1,169) Tanzania (2009, 2011, 2013) (n=2,123) Zambia (2001, 2004, 2008) (n=3,398)

% change in household income per adult (with change in land gini from 25 th to 75 th percentile), Kenya
Summary 1.Landholding distribution influences both the rate and nature of household income growth – in both farm and non-farm sectors All other factors equal, households in districts at the 10 th percentile of farmland inequality (relatively low level of inequality) have 19 to 50% higher farm incomes 28 to 90% higher non-farm incomes significantly higher total incomes per resident adult member than households in districts at the 90 th percentile of farmland inequality (high inequality) Large majority of alternate specifications are highly statistically significant When switching from lagged measures of land concentration to contemporaneous measures, the effect of land inequality becomes more negative and statistically significant 2.Effects of land concentration are most adverse on the rural poor
Policy Questions: Farm structure in many African countries is changing rapidly becoming more concentrated should governments want to influence this?

Policy questions: 1.Farm structure in many African countries is becoming more concentrated – should governments want to influence this? 2.Is rising land inequality contributing to concentration of marketed farm output? Can agric development still be small-farm led? 3.Implications for poverty reduction strategies? 4.Implications for structural transformation processes?
