We develop a model of rational bubbles, based on the assumptions of an unknown potential market size and delegation of investment decisions. In a bubble, the price of an asset rises above its steady-state value, which must be justified by rational expectations about possible future price...

The field of New Economic Geography (NEG) aims at explaining agglomeration based on increasing returns, monopolistic competition and international factor mobility. Deviating from existing approaches, this paper constructs a theoretical model based on capital market frictions. Firms compete...

This paper analyzes how a bank shareholder optimally designs the compensation scheme of a bank manager if there are agency problems between the shareholder and the manager, and how this design changes in reaction to anticipated bail-outs. If there is a problem of excessive risk-taking, bail-out...

In the recent financial crisis, risk management tools have been proven inadequate. Model risk, a key component of bank risk, has shown its negative impact. It seems that risk models did not cover the included risks comprehensively and were not kept up-to-date by banks, and also rating agencies....

One explanation for the poor performance of regulation in the recent financial crisis is that regulators had been captured by the financial sector. We present a micro-founded model with rational agents in which banks may capture regulators due to their high degree of sophistication. Banks can...

The fragility of financial institutions to panic runs depends on their liquidity base: the short term funds available to banks for investment regardless of the withdrawal option available to customers. Institutions that are able to offer higher yield curves are able to lure the liquidity base...

During the COVID-19 pandemic, some goods suddenly became scarce due to panic purchases and stockpiling. The decision to hoard is influenced by higher-order beliefs. If an agent believes that other agents think that a good will become scarce, she concludes that these other agents will hoard, and...

The longer an agent is employed in a job, the more the principal will have learned about his ability through the history of performance. With implicit incentives, influence perceptions and effort incentives decrease over time. Rotating agents to a different job deletes learning effects about...

Crowdfunding, a novel form of financing, has seen massive growth over the last few years. Under crowdfunding, a large number of small households offers small loans to a firm. But if some threshold is missed, the firm cannot draw the loans. We construct a model to argue that this mechanism can be...
