Commercial open source software (COSS) products — privately developed software based on publicly available source code — represent a rapidly growing, multi-billion-dollar market. A unique aspect of competition in the COSS market is that many open source licenses requirefirms to make certain enhancements public, creating an incentive for firms to free-ride on the contributions of others. This practice raises a number of puzzling issues. First, why should airm further develop a product if competitors can freely appropriate these contributions?

The empty creditor problem arises when a debtholder has obtained insurance against default but otherwise retains control rights in and outside bankruptcy. We analyze this problem from an ex-ante and ex-post perspective in a formal model of debt with limited commitment, by comparing contracting outcomes with and without insurance through credit default swaps (CDS).

Firms in several markets attract consumers by offering discounts in other unrelated markets. This promotion strategy, which we call "cross-market discounts," has been successfully adopted in the last few years by many grocery retailers in partnership with gasoline retailers across North America, Europe, and Australia. In this paper, we use an analytical model to investigate the major forces driving the profitability of this novel promotion strategy. We consider a generalized scenario in which purchases in a source market lead to price discounts redeemable in a target market.

The current studies investigate whether different forms of fatalistic thinking follow from the Christian and Hindu cosmologies. We found that fatalistic interpretations of one's own life events center on deity influence for Christians, especially for those high in religiosity; however, Hindu interpretations of one's own life emphasized destiny as much as deity. Also, the focus on fate over chance when explaining others' misfortunes depends on the presence of known misdeeds for Christians, but not for Hindus.
