摘要：This paper describes a series of laboratory experiments studying whether the form in which items are displayed at the time of decision affects the dollar value that subjects place on them. Using a Becker-DeGroot auction under three different conditions-(i) text displays, (ii) image displays, and (iii) displays of the actual items-we find that subjects' willingness-to-pay is 40-61 percent larger in the real than in the image and text displays. Furthermore, follow-up experiments suggest the pres...

摘要：This study considers replacing the current US tax system with only a flat tax consumption tax, showing, in contrast to the literature, that such a reform leads to a decline in inequality and increase in welfare for the welfare-poor. The results are obtained from a simple model that identifies the main channels through which the reform affects the economy. It is shown also that these novel results depend on the distribution of wealth and earnings, and that they hold for the relevant empirical d...

摘要：Empirical work shows that a large majority of individuals get most of their information from a very small subset of the group, viz., the influencers; moreover, there exist only minor differences between the observable characteristics of the influencers and the others. We refer to these empirical findings as the Law of the Few. This paper develops a model where players personally acquire information and form connections with others to access their information. Every (robust) equilibrium of this...

摘要：I develop a novel view of the trade frictions between rich and poor countries by arguing that to reconcile bilateral trade volumes and price data within a standard gravity model, the trade frictions between rich and poor countries must be systematically asymmetric, with poor countries facing higher costs to export relative to rich countries. I provide a method to model these asymmetries and demonstrate the merits of my approach relative to alternatives in the trade literature. I then argue tha...

摘要：The success of new technologies depends on both the firms' investment and consumers' usage decisions. We study this problem in a shared ATM network. Inefficiencies may arise because banks coordinate investment, and consumers may not make proper use of the network. Based on an empirical model of ATM investment and demand, we find that banks substantially underinvested in ATMs, in contrast with earlier findings of strategic overinvestment in the United States. Furthermore, ATM usage was too low,...
