Untitled Land, Occupational Choice, and Agricultural Productivity
研究发现，贫困国家中大量无产权土地导致土地错配和职业选择扭曲，解释了国际农业生产力差异；土地确权可使农业生产力提升高达82.5%。
The prevalence of untitled land in poor countries helps explain the international agricultural productivity differences. Since untitled land cannot be traded across farmers, it creates land misallocation and distorts individuals' occupational choice between farming and working outside agriculture. I build a two-sector general equilibrium model to quantify the impact of untitled land. I find that economies with higher percentages of untitled land would have lower agricultural productivity; land titling can increase agricultural productivity by up to 82.5 percent. About 42 percent of this gain is due to eliminating land misallocation, and the remaining is due to eliminating distortions in individuals' occupational choice.
