A decision-maker is said to have an ambiguous belief if it is not precise enough to be represented by a single probability distribution. The pervasive assumption in game theoretic models in economics is that players' beliefs are unambiguous. This paper argues, drawing on examples from economics...

We analyse a simple model of dynamic moral hazard in which there is a clear and tractable trade-off between static and dynamic incentives. In our model, a principal wants an agent to complete a project. The agent undertakes unobservable effort, which affects in each period the probability that...

This paper analyses a two-player game of strategic experimentation with two-armed bandits.At least one of the arms is risky in the sense that it may not yield a lumpsum payoff. There is payoff externality between the players and they differ in their ability to learn across the risky arm. Either...

A stylized macroeconomic model is developed with an indebted, heterogeneous Investment Banking Sector funded by borrowing from a retail banking sector. The government guarantees retail deposits. Investment banks choose how risky their activities should be. We find that the financial sector can...

We consider a model of financial intermediation with a monopolistic competition market structure. A non-monotonic relationship between the risk measured as a probability of default and the degree of competition is established.

In this paper I make use of Bayesian methods to estimate a firm-specific capital DSGE model with Calvo price and wage setting. This approach allows me to firmly conclude that firm-specific capital is highly relevant in improving the fit of New Keynesian models to the data as shown by a large...

This paper investigates the transmission from UK policy and a range of wholesale money market rates to retail mortgage rates using the long-run estimator proposed by Phillips and Loretan (1991), with a single-equation error correction model (SEECM) framework, from 1995 to 2009. I document the...

By using data on cross-border acquisitions (CBAs), this paper explores the distribution of the strategies pursued when multinational enterprises integrate a foreign subsidiary into their organizational structure. Based on a measure of vertical relatedness, each of the 165,000 acquisitions in our...

We investigate whether subjects’ behavior in the Arad and Rubinstein (2012) "11-20" game could be well explained by the k-level process described by the authors. We replicated their game in our baseline experiment and provided two other variations that retained the same mixed-strategy...

We propose a model of fossil-fuel induced emission, which permits multiple emission-mitigation strategies. In a dierentiable framework, we derive a set of necessary and sucient conditions for an environmental Kuznets curve in terms of the relative responses of the preference and technology-based...
