The study investigates the effect of cognitive skills and use of these skills in various contexts on the immigrant-native wage gap in 14 European countries by using the data from Programme of International Assessment of Adult Competencies (PIAAC). After revealing the significant disparities in cognitive skills between immigrants and native-born respondents we analyze the effect of skills and their use on the wage gap in a multi-level regression model by controlling for individual demographic and occupational characteristics, as well for a set of host-country characteristics, reflecting economic development and social welfare. Gender differences in immigrant-native wage gap and drivers behind it are paid particular attention. Once the skill-related variables are incorporated, the wage gap considerably decreases for both genders although it still remains significant for females. By analysing immigrants with respect to their tenure in the host country, we observe that in the early years of immigration the foreign-born people are significantly disadvantaged in the host country labour markets regardless of their skills. But in later years the use of skills reveals significant association with hourly earnings of immigrants. The wage decompositions show that Spain, Finland, and Estonia are the countries with the highest immigrant-native wage gaps.
Optimization of parameters of a portfolio reinsurance in non-life insurance

This thesis assesses the optimization of reinsurance parameters within a non-life insurance portfolio, focusing specifically on determining the optimal retention levels for two insurance products. The research aims to balance the dual objectives of risk reduction and profitability enhancement, which are crucial for the financial stability and growth of insurance companies. From a broader perspective, it was noted that this trade-off would determine an optimal level of retention which can be applied to both products. To achieve this objective, it was employed two methodologies, utility optimization theory and value at risk. The first one helps determine how much should be kept from what is earned. In contrast, the second one identifies potential maximum loss. It was shown that an increased level of retention may bring about higher profits but at the same time expose the company to significant financial loss calling for a balanced approach in reinsurance.
