The paper focuses on various possibilities of measuring price elasticity of demand with the application of log-log regression analysis. The elasticity measured can be than an input for the optimization process. The critical element of this optimization is the value of the coefficient of price elasticity, which was in the given contribution (for the selected accommodation facility) to the value -0.297, which indicates a price inelastic demand. This approach also has some limitations. It assumes a regression function that is linear in parameters, and also it is only a simple regression. Despite this fact, the results are comparable to other approaches.
