3 The distinction between forecast quality and economic value in a cost-loss 4 formulation is well known. Also well-known is their complex relationship, even 5 with some instances of a reversal between the two, where higher quality is 6 associated with lower economic value, and vice versa. It is reasonable to expect 7 such counter-intuitive results when forecast quality and economic value both,...

Saltcedar (Tamarix spp.) is a widespread invasive plant found in riparian corridors and floodplains in 16 western states. In addition to being associated with such problems as increased soil salinity and decreased plant diversity, saltcedar has been reported to be a prolific water user. Popular press articles widely report that each individual saltcedar tree can use as much as 757 L (200 gallon...

the main objective of this study was to investigate the economic efficiency of investment in sugar beet breeding research in iran. the required information including the value and cost of sugar beet production in 2010 and the budget allocated to the sugar beet breeding research were obtained from the office of statistics and information technology of ministry of jihad-e-agriculture and agricult...

We model virtue as an asset on the marriage market: since men value virginity in prospective mates, preserving their virtue increases girls’ chances of getting a "good" husband, and therefore allows for upward social mobility. Consistent with some historical and anthropological evidence, we find that the diffusion (and the social value) of virginity, across societies and over time, can be deter...

Healthy teeth are a vital and visible component of general well-being, but there is little systematic evidence to demonstrate its effect on labor market outcomes. In this paper, we examine the nature and magnitude of the effect of oral health on labor market outcomes by exploiting variation in access to fluoridated water during childhood. The politics surrounding the adoption of water fluoridat...

Big data has gained significant influence in recent years and is rapidly transforming the business, operations and technology landscape for a myriad of industries. Early adopters — particularly in retail and consumer products — have already derived significant business insights from big data management best practices, such as analysis of both the growing pools of structured transactional data f...

The sum total of funds poured into drug research by profit-seeking commercial entities now overshadows the total of government grants for biological research. An increasing fraction of that sum is earmarked for bioinformatics and genomics. While few if any investment decisions of this kind are based on a precise mathematical analysis, an attempt to quantify the economic value of bioinformation ...

this paper presents a comprehensive theoretical, experimental, and economic study on the application of nanofluids as heat transfer fluid in waste heat recovery systems. the research work was conducted in a steel-making complex in which a plate heat exchanger had been used to recover heat from hot process water. the system was theoretically modelled and the effects of using nanofluids as heat t...
