Purpose: Fine wines challenge the consumer to know them and form a meaningful willingness to pay (WTP) for them. Given the wine consumer’s problem of knowing what she is buying, Nelson’s (1970) idea of “experience goods” might apply—goods that must be “experienced” to be accurately evaluated. Lacking own knowledge, consumers might use expert opinion to guide their WTP. However, the evidence of ...

First, existing studies of WTP for digital services have several weaknesses when it comes to contextand incentive realism and we suggest alternative methods to overcome these weaknesses. Second, a review of existing studies of WTP for digita...

The WTP-WTA gap refers to the often observed difference between the price an individual states he is willing to sell an item (WTA), and the price he states he is willing to pay for the same item (WTP).
