This publication titled “Laboratory of Entrepreneurship and Social Innovation” (PR1) is the result of the work of an international consortium that aimed to contain useful information about starting one’s own capital-intensive business and the best practices from four partner countries. It brings closer the topic of social entrepreneurship and shows good practices connected with the promotion of employment of young people 18-30 and promoting social entrepreneurship in this target group. It focuses on social entrepreneurship and includes innovative aspects of the analysis of social entrepreneurship in the times of the COVID-19 pandemic in partner countries: Poland, Spain, Cyprus and Romania. We would like it to be used by youth workers without additional explanation or costs.
