Integral Options in Models with Jumps [PDF]
We present an explicit solution to the formulated in [17] optimal stopping problem for a geometric compound Poisson process with exponential jumps. The method of proof is based on reducing the initial problem to an integro-differential free-boundary ...

Canadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, EarlyView.Abstract In Quebec, organic‐certification exits remained persistently high at 5% –7% annually over 2021–2025, while entries fell sharply from 10.8% to 3.4%. By 2025, exits exceeded entries for the first time, contracting the certified stock and reversing a decade of expansion.

On Maximal Inequalities for some Jump Processes [PDF]
We present a solution to the considered in [5] and [22] optimal stopping problem for some jump processes. The method of proof is based on reducing the initial problem to an integro-differential free-boundary problem where the normal reflection and smooth
