How large is the economic benefit of merging Pakistan with India, Mexico with US....
Professor Enrico Spolaore and Romain Wacziarg published an interesting study on the economic effect of merging two countries on economic growth. They conduct simulations for large number of potential mergers of geographic neighboring countries. Some results are quite interesting.
In general, small countries benefit from merging with larger countries, and poorer countries benefit from merging with their richer neighbors.
According to the simulation, were Bangladesh to merge with India, she would grow faster by 1-2 % per year, and in the long run, she may double her income. The merger of Argentina (or Bolivia, or Peru, or Paraguay, or Uruguay) with Brazil, or Mexico (or Canada) with the U.S. would create economic benefits of similar magnitude for these smaller neighbors as they get full access to larger markets.
Pakistan’s economic growth rate will increase by 1.2-1.5 % per year, and long-run income level will be double, if she were to merge with India. India on the other hand will not gain much. Indian growth rate would be raised by 0.1%, and in the long run become 10% richer. (This may explains why Indians in general are less interested in signing free trade arrangement with smaller countries such as Thailand.)
Certainly the merger of these two countries with different culture and religion will create social problems that certainly will outweigh the economic benefit. But on the other hand this also sadly highlights the huge economic costs of two countries hating each other for half a century.

Abstract: This paper presents a framework to understand and measure the effects of political borders on economic growth and per capita income levels. We present a model that provides a theoretical foundation to estimate empirically the effects of political borders on growth. In our model, political integration between two countries results in a positive market size effect and a negative effect through reduced openness vis-à-vis the rest of the world. We estimate the growth effects that would result from the hypothetical removal of national borders between pairs of adjacent countries. We also identify zones of mutually beneficial political integration, and discuss the applicability of our framework to European political integration.
