We study an economy where the lack of a simultaneous double coincidence of wants creates the need for a relatively safe asset (money). We show that, even in the absence of asymmetric information or an agency problem, the private provision of liquidity is inefficient. The reason is that liquidity...

In 2012 the National Public Radio program Planet Money created a fake presidential platform based on the issues a small sample of economists, with different political views, agreed upon. In focus groups this platform found no support among the public at large. Is this just a feature of the...

When economists talk about regulatory capture, they do not imply that regulators are corrupt or lack integrity. In fact, if regulatory capture was just due to illegal behavior, it would be easier to fight. Regulatory capture is so pervasive precisely because it is driven by standard economic...

We calculate the costs and benefits of the largest ever U.S. Government intervention in the financial sector announced the 2008 Columbus-day weekend. We estimate that this intervention increased the value of banks' financial claims by $131 billion at a taxpayers' cost of $25 -$47 billions with a...

We design a new, implementable capital requirement for large financial institutions (LFIs) that are too big to fail. Our mechanism mimics the operation of margin accounts. To ensure that LFIs do not default on either their deposits or their derivative contracts, we require that they maintain an...

Entering a currency union without any political union European countries have taken a gamble: will the needs of the currency union force a political integration (as anticipated by Monnet) or will the tensions create a backlash, as suggested by Kaldor, Friedman and many others? We try to answer...

While both cultural and legal norms (institutions) help foster cooperation, culture is the more primitive of the two and itself sustains formal institutions. Cultural changes are rarer and slower than changes in legal institutions, which makes it difficult to identify the role played by culture....

Academics' view of the benefits of finance vastly exceeds societal perception. This dissonance is at least partly explained by an under‐appreciation by academia of how, without proper rules, finance can easily degenerate into a rent‐seeking activity. I outline what finance academics can do,...

In the last few years, there has been a dramatic increase in shareholder engagement on environmental and social issues. In some cases shareholders are pushing companies to take actions that may reduce market value. It is hard to understand this behavior using the dominant corporate governance...

What is so special about banks that their demise often triggers government intervention? In this paper we show that, even ignoring interconnectedness issues, the failure of a bank causes a larger welfare loss than the failure of other institutions. The reason is that agents in need of liquidity...
