Experimental approach to the study of voluntary contribution to public good financing

The purpose of the article is to present the results of the online behavioral experiment focused on voluntary contribution to financing of public goods. The experiment using the public good behavioral game aimed to identify factors affecting voluntary contribution of individuals to financing of public goods. We created a behavioral game design that has elements of a standard public goods game. It was implemented in the form of an online game which was designed as a within-subject experiment. The data collected in the experiment were analyzed using appropriate statistics methods. We used the behavioral and experimental economics methods for designing our behavioral experiment. After the collecting data through online experiment we applied statistics methods to analyze our data, i. e. descriptive statistic, Spearman correlation coefficient and Multiple linear regression model. The results of the study show that an income is a statistically significant variable. Individuals with low income contributed to financing of public goods more than high income individuals. The identification of individuals with such factors as the opinion of the family, the warm-glow effect, the impact on the quality of life and the consent of family, all had a positive effect on individual contributions to financing of public goods. On the opposite side, the identification with factors such as moral obligation, satisfaction with services provided by public goods, the belief in cooperation among people and the perception of contribution as a social norm were all confirmed to decrease the contribution to financing of public goods.
