Information on observable economic and financial variables is sometimes limited to summary form. Therefore, in many practical situations, it is desirable to restrict the flexibility of nonparametric density estimators to accommodate information about the summary data as well as any prior...

The role of unconventional resources (e.g., oil sands and extra-heavy oil) is anticipated to increase in the global oil market. Although we are facing a scarcity of conventional (low cost) oil resources, unconventional oil resources might manage (for a period of time) to supply constraints in...
