Conditions for the convexity of compound geometric tails and compound geometric convolution tails are established. The results are then applied to analyze the convexity of the ruin probability and the Laplace transform of the time to ruin in the classical compound Poisson risk model with and...

Procurement control (PC) is a practice that the buyer controls the material procurement of the supplier and at the same time takes the inventory risk from the supplier. In this paper we compare PC with a decentralized contracting practice (DC) in the setting of a risk-neutral buyer cooperating...

This paper proposes that besides volatility, R&D can increase firms' distress risk through another channel. Unlike capital investment, R&D is more inflexible and subject to high adjustment costs. Moreover, R&D intensive firms face severe financial constraints and are more likely to...
