Regions where the shifts of loss ratios occur are discovered. The values of the competitive effect of the trend for decreasing and increasing rates are estimated, and recommendations on the determination of competitive effect for reducing the effects of level shifts and loss in discovered regions are given.

This study provides a theoretic framework for price promotions on seasonal events and popular events, such as anniversary, Christmas, and World Soccer Cup. Firms engage in collective price promotions seems to contradict economic wisdom because promotions are less likely to stand out among competitors in popular events. In a rational expectations model, this study shows all players’ performance improve in the equilibrium. Furthermore, even less-famous goods benefit from collective price promotions in which the theoretic framework can provide a guideline to manufacturers and retailers.

The paper analyses methods for evaluation of underwriting cycle’s length and their usage in the developed decision support system for formation of effective insurance company strategy. Baxter and King along with symmetric and asymmetric Cristiano and Fitzgerald band-pass filters are applied to ex- tract medium-term cyclical component in loss ratio time series of property, CTP, and property and liabil- ity insurance.
