Abstract:Developed market economies demonstrate a growing interest in issues concerning Corporate Social Responsibility (CSR) and its effects, confirmed by the sizeable theoretical and empirical literature on this issue. A substantial research proves also the positive relation between CSR commitment and financial results of banks in mature markets. However, there is less evidence on CSR existence and its impact in other geographical areas, especially in the research concerning Central and Eastern European Countries (CEEC). In our study we analyze the interrelation between being socially responsible and tangible financial outcome (Corporate Financial Performance-CFP) of banks in the CEEC. The aim is also to empirically verify the relation between efficiency of corporate social-environmental performance (CSP) and the efficiency of CFP for CEEC banks. In our study, we analyze the financial and CSP data of the biggest public banks in CEEC. The researched period is 2012-2016. The empirical part analyzes the interrelation between CSP and CFP based on the panel regression. Moreover, in order to evaluate the CSP efficiency and the CFP efficiency we use the Data Envelopment Analysis (DEA) approach. The empirical results reveal that in case of banks in the Central and Eastern Europe (CEE) region being socially responsible is not reflected in the bottom line. The financial condition of the banks also does not impact the CSR engagement. Our study confirms, however, that CEEC banks with better financial efficiency have higher efficiency of CSR activities. The conclusions may lead to the improved decision-making processes concerning CSR activities and their communication in banks in CEEC.
