内容简介：

While sellinginformation raises fascinating technological questions about data analytics andencryption, it also gives rise to moral questions about responsibility risk. Tomitigate the risk of data leakage, the seller would like to trade a signalrather than full information. A signal can be defined as a mixture of fullinformation and noise. I elaborate the design of signals and make the tradingsignal valuable for the buyer. Regarding signal trading with binarybuyer moral types, I design five kinds of menu for the seller, namely, poolingwithout (ex ante) screening, separation without screening, poolingwith partial screening, separation with partial screening, and perfectscreening. My results show that given the separation menu with both typesparticipating, the seller has to offer a strictly more valuable signal to thelow type. Notwithstanding the fact that the seller fails to send a morevaluable signal to the high type when offering two signals, the pattern ofsignal trading greatly reduces the data leakage risk relative to fullinformation selling. In this sense, ex ante screening plays a leading role indesigning optimal menu for signal trading since it lessens the probability thatthe certified buyer is a low type. I also investigate the case of continuousbuyer moral types and obtain the analytical results based on Envelop Theorem.
