Mohammad, there is a substantial literature on both topics. However, 
before beginning to collect the literature, you may want to form a 
clear idea about what you are looking for.  Are you referring to 
_private_ property rights? Do rights refer to _legal_ rights. Are you 
defining property rights in the abstract sense of _rights to perform 
actions_ that have what are generally agreed to be external effects 
(this is the Coase-Demsetz definition), regardless of whether 
tangible property is involved; or does "property" refer to something tangible?

Most of the professional literature in the field of economics employs 
relatively narrow definitions and deals with relatively minor changes 
in private property rights and its effects on narrowly defined 
economic action. But there is a voluminous literature that defines 
property rights more broadly, incorporating the possibility of 
changes in the political system and effects on culture. Have you 
thought about these questions?

You might start with the Edward Elgar collection. Go to the 
publishers website and search "property rights" or "economics of 
property rights." They have a number of collections of articles.
