In the paper, we simulate a heterogeneous-agent version of the wage-posting model as derived by Montgomery (1991) with homogeneous workers and differently-productive employers. Wage policy of particular employer is positively correlated with employer’s productivity level and the wage policy of...

Numerous economic models employ a continuum of negligible agents with a sequence of idiosyncratic shocks and random matchings. Several attempts have been made to build a rigorous mathematical justification for such models, but these attempts have left many questions unanswered. In this paper, we...

This paper introduces a model of sweet talk in which a seller may acquire verifiable information and selectively disclose it to a buyer to negotiate a deal. We start by analyzing a model with common priors in which the seller generates information for two reasons: a trading motive and a profit...

This paper investigates how trading frictions vary with the thickness of the asset market by examining patterns of asset allocations and prices in commercial aircraft markets. The empirical analysis indicates that assets with a thinner market are less liquid—i.e., more difficult to sell. Thus,...

The paper discusses opportunities to utilize the series of micro-blogs as provided by the Twitter in observation of opinion dynamics. The spontaneity of tweets is more, as the service is attached more to the mobile communications. The extraction of information in the series of tweets is...

We present an equilibrium search model of competing mechanisms where some buyers are budget constrained. Absent budget constraints, the existing literature capitulates that if buyers differ in their valuations then in the unique equilibrium all sellers hold second price auctions (e.g. McAfee...

Short-lived buyers arrive to a platform over time and randomly match with sellers. The sellers stay at the platform and sequentially decide whether to accept incoming requests. The platform designs what buyer information the sellers observe before deciding to form a match. We show full...

Are individuals always better off when their preferences can be represented by expected utility? I study this question in a bargaining game where individuals bargain over a pie of fixed size, and I contrast the share received in the long-run by expected utility maximisers with the share they...

Many economic models use a continuum of negligible agents to avoid considering one person's effect on aggregate characteristics of the economy. Along with a continuum of agents, these models often incorporate a sequence of independent shocks and random matchings. Despite frequent use of such...
