The optimal stopping times of the exercise are shown to be the first times at which the price of the underlying asset exits some regions restricted by certain boundaries depending on the running values of the associated maximum and maximum drawdown processes. We obtain closed-form solutions to the equivalent free-boundary problems for the value functions with smooth fit at the optimal stopping boundaries and normal reflection at the edges of the state space of the resulting three-dimensional Markov process. We derive first-order nonlinear ordinary differential equations for the optimal exercise boundaries of the perpetual American standard options.<\/jats:p>","DOI":"10.1017\/s0021900200011682","type":"journal-article","created":{"date-parts":[[2016,3,29]],"date-time":"2016-03-29T10:50:01Z","timestamp":1459248601000},"page":"799-817","source":"Crossref","is-referenced-by-count":0,"title":["Optimal Stopping Problems in Diffusion-Type Models with Running Maxima and Drawdowns"],"prefix":"10.1017","volume":"51","author":[{"given":"Pavel V.","family":"Gapeev","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Neofytos","family":"Rodosthenous","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2016,2,19]]},"reference":[{"volume-title":"Essentials of Stochastic Finance","year":"1999","key":"S0021900200011682_ref30"},{"key":"S0021900200011682_ref21","doi-asserted-by":"publisher","DOI":"10.1239\/jap\/1014843077"},{"key":"S0021900200011682_ref18","doi-asserted-by":"publisher","DOI":"10.1016\/j.spa.2012.06.012"},{"volume-title":"Statistics of Random Processes I","year":"2001","key":"S0021900200011682_ref17"},{"volume-title":"Brownian Motion and Stochastic Calculus","year":"1991","key":"S0021900200011682_ref16"},{"key":"S0021900200011682_ref15","doi-asserted-by":"publisher","DOI":"10.1214\/aop\/1176990237"},{"key":"S0021900200011682_ref9","doi-asserted-by":"publisher","DOI":"10.1239\/jap\/1189717540"},{"key":"S0021900200011682_ref14","doi-asserted-by":"publisher","DOI":"10.1016\/j.spa.2010.02.008"},{"key":"S0021900200011682_ref8","doi-asserted-by":"publisher","DOI":"10.1239\/aap\/1377868542"},{"key":"S0021900200011682_ref13","doi-asserted-by":"publisher","DOI":"10.1239\/jap\/1005091029"},{"key":"S0021900200011682_ref7","doi-asserted-by":"publisher","DOI":"10.1016\/j.spa.2011.07.009"},{"key":"S0021900200011682_ref12","doi-asserted-by":"publisher","DOI":"10.1023\/A:1021659328029"},{"key":"S0021900200011682_ref6","first-page":"627","volume":"4","year":"1963","journal-title":"Soviet Math.
