ABSTRACT
The chapter examines the degree of competitiveness on the Polish non-life insurance market in the years 2010–2018. In the analysis of competitive conditions, the Panzar-Rosse methodology was used. The estimation of the reduced revenue model was done using a two-step Generalized Method of Moments (2-step GMM). The second assumption of the Panzar-Rosse model, i.e. the long-term equilibrium in the non-life insurance market, is also verified. The Panzar-Rosse model used in the study also considered the control variables representing company size, leverage, loss, and equity ratios. The results of the study confirmed the hypothesis that the non-life insurance market in Poland functioned under the conditions of monopolistic competition and was in a state of long-term equilibrium.
