  • Can land markets reduce land inequality in developing countries?

    About 77 percent of Paraguay's arable land is controlled by 1 percent of the nation’s landowners, according to the last agricultural census, and land disputes simmer in various parts of the country.

    Land inequality in developing countries has been found to hamper long-term economic growth and also mitigate the poverty-reducing effects of existing growth by limiting effective access to land by the rural poor. Further, given the often-observed inverse relationship between farm size and productivity, land inequality can adversely affect agricultural productivity.

    While land allocation has historically been driven by inheritance and land reform initiatives, in recent decades markets for the rental or sale of land have become considerably more prominent. So, how might the rise of such private, market-led initiatives affect land inequality? 

    A number of theories offer insights as to how household-level characteristics might affect land accumulation patterns. Credit and labor  market imperfections, tenure insecurity and household characteristics have played a central role in the leading accounts. Other theories have emphasized managerial experience, human capital, and even stochastic accumulation.

    While little effort has been devoted to testing these hypotheses, a recent IDB working paper by Henderson et al. (2014) attempted to do just that, using the Paraguayan case as an illustrative example. Paraguay is a particularly appropriate setting due to the country’s history of land inequality and conflict as well as the scope of its recent economic liberalization efforts.

    In brief, the authors found that initial farm size and whether the producer’s land was titled significantly affect subsequent land accumulation.  Given these findings, it is interesting to examine how we might expect land inequality to develop, at least in the Paraguayan case.

    Figure 1 plots predicted farm growth against farm size and suggests three distinct growth regimes: (1) those farms operating less than approximately 5.5 hectares tend toward positive growth rates until reaching an equilibrium size of 5.5 hectares; (2) those farms operating between 5.5 and 350 hectares tend toward negative farm growth until arriving at the same equilibrium of 5.5 hectares; and (3) those farms operating greater than approximately 350 hectares appear to persistently grow.

    Figure 2 plots the results from a hypothetical reform through which all households are provided formal title to all land owned. Relative to the baseline scenario (ex ante), the policy scenario (ex post) suggests that tenure reform may act to slow the rate at which inequality manifests, but such reforms do not fundamentally alter the aforementioned “accumulation barriers.”

    So, wither land inequality? While the above evidence is by no means exhaustive, it does suggest that the emergence of land markets in and of itself in developing countries does not hold great promise for reducing land inequality. The evidence does, however, point toward mechanisms that might be exploited for policy purposes. For example, if credit market imperfections are indeed central to land accumulation, then policymakers might reduce inequality though, say, expanding credit access in rural areas. Thus, while land markets themselves may not be equality inducing, policy options indeed exist if observed inequality is considered sufficiently costly.
