Economists have long recognized the importance of trust, but how can trust be enhanced in a marketplace? We set up a rational expectation model that allows the marketplace to target buyer trusting (via a buyer protection program) and seller trustworthiness (via penalty on cheaters) separately. We show that these two policies have opposite effects on the equilibrium level of trust: buyer protect...

In biotransformations carried out under similar conditions enzymatic systems from carrot (Daucus carota L.), celeriac (Apium graveolens L. var. rapaceum) and horse-radish (Armoracia lapathifolia Gilib.) hydrolyzed the ester bonds of acetates of phenols or alicyclic alcohols. Nevertheless, methyl esters of aromatic acids did not undergo hydrolysis. Alcohols were oxidized to ketones in a reversib...

Reputation systems aim to induce honest behavior in online trade by providing information about past conduct of users. Online reputation, however, is not directly connected to a person, but only to the virtual identity of that person. Users can therefore shed a negative reputation by creating a new account. We study the effects of such identity changes on the efficiency of reputation systems. W...

We study a bargaining model in which a buyer makes frequent offers to a privately informed seller. In addition, the buyer gradually learns about the seller’s type from a publicly observable news process. We show that the buyer’s ability to leverage this information to extract more surplus from the seller is remarkably limited. In fact, the buyer’s equilibrium payoff is identical to what he woul...
