## hos_small_open.gms


*
*   --- Small country trading equilibrium

*
*       Different variants of the same model:
*
*
*       (1) explicit trade balance condition [import value = export value] or 'nested' budget constraint [max. income = production value]

## salhofer1996.gms
* GAMS code based on the bread grain market model in
* Salhofer (1996), “Efficient Income Redistribution for a Small Country Using Optimal Combined Instruments.”

* Salhofer, K. 1996. “Efficient Income Redistribution for a Small Country Using Optimal Combined Instruments.” Agricultural Economics 13 (3): 191–99. doi:10.1016/0169-5150(95)01162-5.


* The code builds on Salhofer's GAMS example provided in the course "Welfare Economics"

* General idea of the optimization model:
* Maximizes consumers/taxpayers surplus s.t. a given support level and four policy instruments
