Sellers often make explicit or implicit product claims without providing evidence. We show that such "puffery" of product attributes through pure cheap talk can be credible and help buyers make a better decision. Puffing one attribute of a product leads buyers to positively update their...

We study the effect of noise due to exogenous information distortions in the context of Bayesianpersuasion. In particular, we ask whether more noise (a la Blackwell) is always harmful forthe information designer, i.e., the sender. We show that in general this is not the case. Weprovide a...

We experimentally examine the impact of tax evasion attempts on the performance of credence goods markets, where contractual incompleteness results from asymmetric information on the welfare maximizing quality of the good. Our results suggest that tax evasion attempts - independently of whether...

In Buy-It-Now (BIN, hereafter) auctions, sellers can make a "take-it-or-leave-it" price offer (BIN price) prior to an auction. We analyse experimentally how eBay sellers set BIN prices and whether they benefit from offering them. Using the real eBay environment in the laboratory, we find that...

Our study proposes a novel mechanism to reduce information asymmetry about product quality between buyers and sellers. Product testing organizations like Consumer Reports (US) and Stiftung Warentest (Germany) seek to reduce this asymmetry by providing credible information. However, limited...

We investigate experimentally on eBay how sellers set prices in "Buy-It-Now" (BIN) auctions. We find that the eBay format leads to prices substantially below those expected in second-price auctions. Moreover, our results reveal that the information available on eBay about buyer experience and...
