A Coasian perspective on informal rights assignment among waste pickers in the Philippines
从科斯定理出发，研究菲律宾一个原本开放的垃圾填埋场如何通过划定可执行权利来影响拾荒者的市场交易，发现简单排斥不够，非政府组织与政府协助能降低交易成本、促进创新。
This paper examines in light of the Coase Theorem how delineation of a degree of enforceable rights for a previously open-access dumpsite in the Philippines would affect market transactions of waste pickers. It shows that a simplistic exclusion solution was not enough to constrain rent dissipation of recyclables in the primeval land fill. Some intervention of non-government organisations backed by some initial government assistance were found helpful in reducing transaction costs to sustain operations and promote innovations and initiatives from the scavengers themselves despite obvious external economic difficulties.
