Abstract
Poniższa praca jest poświęcona dynamicznemu modelowi samoubezpieczenia. Dowodzimy, że wzrost awersji do ryzyka nie jest wystarczającym warunkiem do wzrostu inwestycji w samoubezpieczenie, jak to ma miejsce w statycznym modelu (Dionne i Eeckhoudt). Wykazujemy, że czynnikami, które mają wpływ na decyzję są także wzajemne relacje między wielkością straty a dochodami teraźniejszymi oraz przyszłymi. Rozważamy także przypadki inwestycji w samoubezpieczenie w okresie poprzedzającym ryzyko straty, jak i w obu okresach. Wykazujemy przy tym, że oba przypadki różnią się z ekonomicznego punktu widzenia. (abstrakt oryginalny)

This work shows that in a two-period framework increase in risk-aversion is not a sufficient condition to invest more in self-insurance, as it is in one-period setting (Dionne and Eeckhoudt). We prove that other factors important for decision-making exist. Rela-tionship between size of loss and future and present income is crucial in this problem. We consider two cases - when an effort to prevent risk precedes its effect and when it is sim-ultaneous. We show that those cases are mathematically and economically different. (original abstract)
