A 'Live' Version of the HOS Model in Excel

We present a numerical version of the factor proportions (Heckscher-Ohlin-Samuelson) model of production in a small economy, built in Excel. The model features the most common graphical devices used to explain the model properties. It differs from earlier work in that the solution is embedded in the sheet, making the use of the Solver add-in unnecessary. The equilibrium values and graphics respond instantly to changes in parameters/exogenous variables. The model can be used to demonstrate the Stolper-Samuelson and Rybczynski theorems, as well as other scenarios.
