In order to create value, companies must allocate their resources effectively and evaluate investment alternatives. This book examines, from a theoretical and empirical point of view, how managerial flexibility can be integrated into investment decisions through the optional approach. Unlike the traditional net present value method, the actual options take into account indeterminate elements. These lead to unpredictable cash flows at the time of the investment decision, especially in the context of complex and risky projects. The book puts into perspective the use of optional models and their interactions. The different categories of options are the subject of practical applications, through analysis of investment decisions where uncertainty is growing. Therefore, studies make it possible to consider the flexible nature of investment choices by integrating new information and risk over time.

In France, the number of young start-ups has soared since the beginning of the 2010s, leading the government to encourage their development and make France the "start-up nation". This book contributes to a better understanding of the emergence of these companies by studying the influence of the ecosystem on their development and the modes of financing that they use. The financing of start-ups remains a major challenge insofar as they are often faced with refusal from the banks. Successful financing depends largely on the geopolitical and economic environment. Through a comparative study of models from both France and English-speaking countries, the authors explore possible financing solutions for France. The book concludes with a discussion of equity crowdfunding, which proves to be a successful financing alternative. Including theoretical and empirical studies, this book provides concrete solutions aimed at developing innovative entrepreneurship in France.
