Besides signaling complementary types, investments also generate benefits for partners. We shed light on quantitative properties of the equilibrium investment behavior. The bilateral external benefits induce an investment multiplier effect. This multiplier effect depends in a complex way on agents' uncertainty about their rank within their own market side and on their uncertainty about the types and investments of potential partners. We study how the multiplier effect depends on market size and how it interacts with other important factors such as the costs of investment and the signaling incentives induced by competition for more desirable partners. We use our results to characterize equilibrium utilities in large markets. For small markets, our results lead to bounds on the hold-up problem.","PeriodicalId":420730,"journal":{"name":"ERN: Bargaining Theory (Topic)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126220556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Upon a match, they bargain over borrowing limits and borrowing interest rates — fixed for the duration of the match. Using the model, I show that improved matching between consumers and credit card firms, calibrated to match the rise in the population with credit cards, accounts for the rise in revolving credit and consumer bankruptcies in the United States. I also provide empirical evidence consistent with the two key features in my model: directed search and bargaining. The lifetime consumption gains from improved matching are 3.55 percent— substantially larger than those previously estimated by alternative explanations for the rise in revolving credit and consumer bankruptcies (0.03-0.57 percent). Finally, I analyze how the credit card firm’s bargaining power impacts the welfare of introducing stricter bankruptcy laws.","PeriodicalId":420730,"journal":{"name":"ERN: Bargaining Theory (Topic)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130393469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our model provides a continuous link between models of matching with and without transfers. Taxes generate inefficiency on the allocative margin, by changing who matches with whom. This allocative inefficiency can be non-monotonic, but is weakly increasing in the tax rate under linear taxation if each worker has negative non-pecuniary utility of working. We adapt existing econometric methods for markets without taxes to our setting, and estimate preferences in the college-coach football market.

I then construct a double limit that approximates the Nash Bargaining split in the ex-post surplus, but with a delay. Further, I prove the Folk theorem when the range of the buyer's values coincides with the range of the seller's costs: any feasible and individually rational ex-ante payoff profile can be approximated by a double limit.","PeriodicalId":420730,"journal":{"name":"ERN: Bargaining Theory (Topic)","volume":"04 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129059105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, variation in the firms’ markups serves as an important determinant of wage distribution. We provide micro foundations for this channel of wage determination. \u0000We test the model on the sample of Ukrainian firm-level data. We find that the average wage rises with an increase of the firm productivity, but falls with an increase of the market power.

Damages from climate change typically occur after long delays and can take the form of more frequent realizations of extreme and random events. These features generate a decoupling between emissions and their damages, which we study through a laboratory experiment. We find that some decision-makers respond to global emissions, as expected, while others respond to realized damages also when emissions are observable. On balance, the presence of delayed/stochastic consequences did not impair cooperation. However, we observed a worrisome increasing trend of emissions when damages hit with delay.

In these markets, time waited in line often plays the role of a numeraire. We investigate the properties of equilibrium in these markets (existence, uniqueness, and welfare).

We show that the endowment effect increases the sellers information rent, and that the attachment effect reduces the buyer’s information rent. Further, depending on the distribution of types, loss-aversion can reduce the severity of the impossibility problem. However, the result cannot be reversed. Turning to the design of optimal mechanisms, we show that in both revenue and welfare maximizing mechanisms the designer optimally provides the agents with full insurance in the money dimension and with partial insurance in the trade dimension. In fact, when the stakes are large, loss-aversion can eliminate trade altogether. We show that all results display robustness to the exact specification of the reference point and provide some results on general mechanism design problems.","PeriodicalId":420730,"journal":{"name":"ERN: Bargaining Theory (Topic)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127368149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We experimentally test whether real market participants can report their real preferences for course schedules “accurately enough” for a novel course allocation mechanism, approximate competitive equilibrium from equal incomes (A-CEEI), to realize its theoretical benefits. To use market participants’ real preferences (i.e., rather than artificial “induced preferences” as is typical in market design experiments), we develop a new experimental method. Our method, the “elicited preferences” approach, generates preference data from subjects through a series of binary choices. These binary choices reveal that subjects prefer their schedules constructed under A-CEEI to their schedules constructed under the incumbent mechanism, a bidding points auction, and that A-CEEI reduces envy, suggesting subjects are able to report their preferences accurately enough to realize the efficiency and fairness benefits of A-CEEI. However, preference-reporting mistakes do meaningfully harm mechanism performance. One identifiable pattern of mistakes was that subjects had relatively more difficulty reporting cardinal as opposed to ordinal preference information. The experiment helped to persuade the Wharton School to adopt the new mechanism and helped guide aspects of its practical implementation, especially around preference reporting.
