Trust and firms' performance in Western Balkan countries.

The purpose of the paper is to analyse the effects of interpersonal trust in business relations (proxied by trade credit) and institutional trust (proxied by firms' trust in courts) on firms' performance. The analysis is performed on a specific sample of 1298 firms in Western Balkan countries which are usually characterized by negative social capital that is considered to hinder economic and social development at all levels. The methodological approach is based on the propensity score matching method and the obtained results show that firms' perception of courts as fair, impartial and uncorrupted, is connected with lower costs and with positive expectations of an increase in sales in the upcoming period. On the other side, trade credit as a trust variable has a statistically significant and positive effect on firm productivity measured as sales per employee and on expectations of an increase in sales in the upcoming period. The paper contributes to the existing literature in terms of the choice of the post-socialist groups of countries for the analysis, the method that is used (treatment-effects estimation), and in terms of performing firm-level analysis of the effects of two types of trust on selected variables of firm performance.
