Physics is the search for and application of rules that can help us understand and predict the world around us. Central to physics are ideas such as energy, mass, particles and waves. Physics attempts ...

Molecular dynamics is a method that uses Newton’s equations of motion to computationally simulate the time evolution of a set of interacting atoms. Such techniques are dependent on a description of ...

Can idiosyncratic risk explain the equity premium? We revisit this question using a novel measure of imperfect risk sharing, implied by a large class of heterogeneous-agent models, constructed using ...
