Traditionally, economic experiments have been carried out in laboratory environments. In recent years, extra-laboratory experiments have become increasingly widespread. Extra-laboratory experiments are experiments performed in environments that differ from the laboratory setting (e.g., Internet-based experiments). Internet-based experiments enable the experimenter to perform studies without spatial restrictions. One example of (Internet-based) individual experiments is given by business management games. In business management games, the experimental subjects are confronted with a real-world context, and their behavior is observed over multiple periods. In many areas of life, reliable predictions of human behavior in response to institutional innovations are required. This includes entrepreneurial adaptation processes in the environmental sector. The primary goal of the thesis is to analyze the suitability of Internet-based business management games as instruments for evaluating institutional innovations in the environmental sector. It must be examined, first, whether the research goal and the experimental design go hand in hand. Furthermore, the experimenter has to focus on determinants such as practicability and costs. However, to receive reliable forecasts of how humans behave in response to changes in their legal environment, scientists are required to replicate business management games.
