Michael Spence is a winner of Bank of Sweden Prize in Economic Sciences in Memory of Alfred Nobel, along with George A. Akerlof and Joseph E. Stiglitz, for their work on the dynamics of information flows and market development. In the current technological environment - with ever more abundant information flows about market development, prices, profit margins, investment instruments and rates of return - their work is more relevant than ever.

Michael Spence is probably most famous for his job-market signaling model, which essentially triggered the enormous literature in this branch of contract theory. In this model, employees signal their respective skills to employers by acquiring a certain degree of education, which is costly to them. Employers will pay higher wages to more educated employees, because they know that the proportion of employees with high abilities is higher among the educated ones, as it is less costly for them to acquire education than it is for employees with low abilities. For the model to work, it is not even necessary for education to have any intrinsic value if it can convey information about the sender (employee) to the recipient (employer) and if the signal is costly.
