摘要：
Local protectionism disrupts buyer-supplier chains, since it requests local firms to buy the outputs of other local firms as inputs. Hence, it is an important factor for firms' location choices, as buyer-supplier chains affect profitability. I study how local protectionism shapes the spatial allocation of firms through disrupting production networks. Using a spatial regression discontinuity design, I find that local protectionism causally affects firm entry and exit. A novel spatial quantitative model indicates that eradicating local protectionism enhances welfare, by facilitating interregional transactions.

摘要：
In many economic situations, a sender communicates strategically with a receiver not only to influence the decision-making of the latter, but also how certain intrinsic characteristics of herself (e.g. selfishness, integrity) are perceived by the latter. To study such strategic interactions, we introduce image concerns to the canonical framework of information design. Our main result characterizes how the sender optimally sacrifices her material utilities to boost reputation by manipulating the communication protocol of a payoff-relevant state. The presence of image concerns may increase or decrease the receiver's welfare, and its effect can be non-monotone. Our analysis provides new insights into various applications, such as how performance evaluation in organizations can backfire by engendering harmful signalling, or the use and misuse of populist rhetoric in political elections.
