+  A study looking at the effects of minimum wage increases on a country's income inequality, looking at the impacts in a sample of 43 countries, both LMIC and HIC.
+  Using a general-equilibrium model, it finds that there are differences between the short-term and long-term effects of the increase:
+  In the short term it leads to a reduction of the skilled-unskilled wage gap, however an increase in unemployment and welfare, 
+  while in the long term the results are an overall decrease in wage inequality as well as improved social welfare.
+  It finds those results primarily stem from LMIC which experience significant effects driven by a long-term firm exit from the urban manufacturing sector thereby increasing available capital for the rural agricultural sector, while in HIC the results remain insignificant.
+  The study uses the Gini coefficient for identifying a country's inequality.
+  Some limitations of the study include the necessity to omit short-term urban firm exit for the impact to be significant, as well as requiring the, reasonable but necessary, prior assumption of decreased inequality through increased rural agricultural capital.

In the short run without entry/exit of manufacturing firms, an increase in the urban minimum wage reduces the skilled-unskilled wage gap but worsens unemployment and welfare in the economy. In the long run, a higher minimum wage induces firms to exit the urban manufacturing sector, thereby releasing capital to the rural agricultural sector. This can yield double dividends by further narrowing wage inequality and improving social welfare. Empirical results based on data from 43 selected countries confirm our theoretical findings.},
