This paper observes a job search problem on a partially observable Markov chain, which can be considered as an extension of a job search in a dynamic economy in [1]. This problem is formulated as the state changes according to a partially observable Markov chain, i.e., the current state cannot be observed but there exists some information regarding what a present state is. All information about...

Merchant reputation is a collective measure of trustworthiness derived from a combination of received referrals and consumer past purchase experience. The positive influence of merchant reputation on consumers’ responses and attitudes has received much attention, particularly in terms of the connection between trust and merchant reputation.

Supply contracts are a medium for coordinating materials and information flows in supply chains aiming at reducing uncertainties, order variances, delivery lead times, and inventory risks with increased fill rates. Practitioners were always up-front involved in designing and negotiating clauses of so called quantity flexibility contracts. Meanwhile researchers have proved the advantage of such ...

The literature on interlinkage is inconclusive regarding the strict superiority of this arrangement. We analyze a landlord and a moneylender as two players making non-cooperative decisions regarding the terms of their respective contracts with a tenant. In the sequential game where the landlord moves first and the tenant has limited liability, we demonstrate that there exist circumstances in wh...

In this paper, Black Scholes’s pricing model was developed to study American option on future contracts of Brent oil. The practical tests of the model show that market priced option contracts as future contracts less than what model did, which mostly represent option contracts with price rather than without price. Moreover, it suggests call option rather than put option. Using t hypothesis test...

Organic molecules dominate the biological world, yet many of life’s critical molecular reactions depend on metals for catalysis. Sabeeha Merchant, a professor of biochemistry at the University of California, Los Angeles (UCLA), studies how cells keep track of crucial trace nutrients like iron and copper. Her early work on Chlamydomonas reinhardtii, a single-celled alga that, like all plants, pr...
