In the last few years, a re?ned pricing of corporate securities has come intofocusofacademicsandpractitioners.Asempiricalresearchshowed, traditionalassetpricingmodelscouldnotpricecorporatesecuritiess- ?ciently well. Time series properties of quoted securities were di?cult to replicate. In the search for more advanced models that capture the empirical ?ndings, researchers followed two approaches. The ?rst stream of - search ?tted the time series properties of corporate securities directly.

All studiesofthistypedonot consider the economics of the issuing companies but simply assume a stochastic behavior of the security or its state variables. In contrast, a second, economic literature developed by studying the ?rm. We call these kinds of models structural because the limited liability of equity holders is modeled explicitly as a function of ?rm value. One problem of the reduced form approach is its di?culty of int- pretation in an economic sense. Being technically advanced, reduced form models often lack an intuitive economic model and especially d- guise the economic assumptions. If security pricing is the only purpose of the exercise, we might not need an economic model. However, if we wanttounderstandpricemovements,aseriouslinkwiththeunderlying economics appears important.
