Abstract
This study investigates the impact of formal property rights on agricultural investment and the channels – access to credit, tenure security, and gains from trade – through which this effect may occur. The research question will be tested within the context of the Comprehensive Agrarian Reform Program (CARP) in the Philippines, where collective titles have been issued to groups of farmers as a transition mechanism to hasten the land acquisition and distribution process. The government is now subdividing these collectively titled lands to formalize individual property rights (referred hereafter as parcelization), and the study will exploit this program to conduct a cluster-randomized controlled trial (randomizing collective titles into treatment and control groups) with the goal of understanding the impact of rights on investment and the degree to which the lack of formal rights limits financial market development.

Experimental Details
Interventions
Intervention(s)
The intervention being evaluated is the parcelization program described in the abstract. The Department of Agrarian Reform is subdividing land that is collectively titled by conducting land surveys and issuing individual titles to those farmers previously listed under the collective title. Note that although land may be collectively titled, a distinction must be made between farm ownership and management: most of the farms under these titles are farmed individually, not collectively.

Experimental Design
Experimental Design
The heart of the evaluation design is a cluster-randomized controlled trial that randomly selects collective titles to be subdivided, or "parceled out". The control group will not be parcelized for at least two years of the evaluation, allowing sufficient time for farmers to make significant agricultural investment decisions before a follow-up survey is conducted.
Experimental Design Details
We will collect data on farmers' parcels whether they are inside the subdivided area or not. This will help us at follow-up to distinguish between different mechanisms behind investment by comparing 'outside' parcels (outside of the subdivided area) of farmers in the treatment and control groups. These are not affected by new sets of property rights we may detect investment changes due to increased access to capital or other types of spillover effects from getting property rights over land inside the subdivided area.
