Adding unlicensed spectrum, such as the recent opening of the television white spaces in the US, has the potential to benefit customers by increasing competition, but may also increase congestion. In an earlier paper, we presented a model for studying the effects of adding unlicensed spectrum to an existing allocation of licensed spectrum among incumbent service providers. Assuming that custome...

We consider a firm selling a fixed amount of inventory to customers who possess uncertain valuations on a product prior to purchase and realize their complete valuations only after purchase. The firm determines the returns policies over two periods; each of which targets for a group of brand loyal customers or regular shoppers. The customers are strategic, taking into account both the product a...

The late Chile born biologist Francisco J. Varela has been influential in theoretical biology throughout the last three decades of the 20. century. His thinking shows a marked development from a biologically founded constructivism (developed together with his fellow citizen, Humberto Maturana, with the main key word being “autopoiesis theory”) to a more phenomenological oriented standpoint, whi...

A common problem encountered in steel companies is that of allocating the surplus slabs to customer orders so as to minimize the total cost of production and inventory. Due to many unpredictable events arising in practical manufacture environment, slab yields and customer demands are full of uncertainties. This paper focuses on such uncertainties and studies the stochastic version of the slab a...

I identify assumptions under which policies that maximize expected surplus are Pareto Optimal–even when expected consumer surplus does not even locally represent preferences over price-income lotteries. Besides the oft-made partial equilibrium assumptions that only one price varies, and that income changes do not affect demand, the two other assumptions are that every consumer’s indirect utilit...

Cash forecasting plays a vital role in any financial organization to maintain the optimal cash balance to satisfy the customer needs on a daily basis without any delay. In the traditional approach statistical methods were used for cash forecasting. Banks have great challenges to avoid the surplus cash as well as to keep adequate cash to meet the customer demand. An intelligent model is needed t...
