This article reports the main results of the 2013 Risk Premium Project update, a yearly review of actuarial and finance literature on the theory and empirics of risk assessment for property-casualty insurance. The literature review reveals a broad variety of topics, with a strong leaning toward catastrophe risk, market efficiency, and new valuation techniques. Within the field of catastrophe risk, the role of weather and climate-related risks for the insurance sector is reviewed and both the threats and the opportunities arising from the changing risk landscape are discussed.
