[영문]As of the early 21st century, one of the most popular uses of the internet is for online shopping. In this study I examine how online purchasing affects levels of generalized social trust, a quality widely believed to be central to the health and well-being of contemporary societies. Drawing on two original studies, including an experiment embedded in a representative national survey, and a hybrid laboratory/field experiment, I find consistent evidence that positive e-commerce experiences promote generalized social trust. I discuss the implications of these findings for the role of business in helping to maintain attitudes supportive of democracy.
