This Paper introduces and formally models the variable value environment, where bidders' private values may change over time as a result of both private actions and exogenous shocks. Examples of private actions and exogenous shocks are complementary investments and exogenous changes in bidder's...

We analyze an environment in which biddersʼ private values change over time due to both private investments and exogenous shocks. We demonstrate that a highly-decentralized mechanism achieves efficiency. The mechanism requires a stage of costly public announcements (i.e., signaling) to induce...

In sport tournaments, the rules are presumably structured in a way that any team cannot be better off (e.g., to advance to the next round of competition) by losing instead of winning a game. Starting with a real-world example, we demonstrate that the existing national rules of awarding places...

Though new media has become a popular source of information, it is less clear whether or not they have a real impact on economic activity. In authoritarian regimes, where the traditional media are not free, this impact might be especially pronounced. We study consequences of blog postings of a...

In terms of output decline and increase in unemployment, the economic recession in Latvia that started during the 2008-09 financial crisis was one of the most severe in the world. Using both decomposition of the unemployment rate into structural and cyclical components and Mortensen and...

In elections that take place in a less-than-perfect democracy, incumbency advantages are different from those in mature democracies. The incumbent can prevent credible challengers from running, organize vote fraud, or even physically eliminate the main opponents. At the same time, formally...

There has been a wide-spread belief that elections with a wide franchise following removal of an oppressive dictator lead to establishment of a government that is not vulnerable to mass protest. At the same time, most of the post-World War II non-constitutional exits of recently-installed...

We study the impact of information revelation on efficiency in auctions. In a constrained-efficient mechanism, i.e. a mechanism that is efficient subject to the incentive-compatibility constraint, any additional information available to bidders increases the expected efficiency of the mechanism....
