Introduction

In their chapter, "A method to compute a peace gross world product by country and by economic sector", Jurgen Brauer and John Tepper Marlin present a novel method to assess the economic value of peace, in both the domestic and international realms. This is not only a tool for assessing and forecasting the potential benefits of reduced violence, but it is an example of best social science practice in that by design it incorporates the best existing knowledge on the effects of peace. This approach combining meta-analysis with a novel integrating framework is quite promising. For the purposes of the book, it sets the stage nicely for the subsequent chapters by highlighting the big picture of expected welfare gains from peace, within a rigorous scientific context, rather than one of advocacy. Estimating the potential economic benefits of internal and international peace is also fundamental in understanding the potential economic incentives which might drive political and business leaders to avoid deadly conflict, and pursue peace.
