Trade liberalization between two countries reduces probability of an armed con ict between them, causing both to cut defense spending.

We estimate the model using data on trade, con icts, and military spending.

The Strategic Market Game (SMG) is the general equilibrium mechanism of strategic reallocation of resources. It was suggested by Shapley and Shubik in a series of papers in the 70s and it is one of the fundamentals of contemporary monetary macroeconomics with endogenous demand for money. This survey highlights features of the SMG and some of the most important current applications of SMGs, especially for monetary macroeconomic analysis.
