Merger control authorities may approve a merger based on a so-called 'efficiency defence'. An important aspect in clearing mergers is that the efficiencies need to be merger-specific. Joint ventures, and in particular research joint ventures (RJVs), may achieve comparable efficiencies possibly...

We analyze tacit collusion in an industry characterized by cyclical demand and long-run scale decisions; firms face deterministic demand cycles and choose capacity levels prior to competing in prices. Our focus is on the nature of prices. We find that two types of price wars may exist. In one,...

The influence of peers could play an important role in the take up of social programs. However, estimating peer effects has proven challenging given the problems of reflection, correlated unobservables, and endogenous group membership. We overcome these identification issues in the context of...

We propose a theory of monetary policy and macroprudential interventions in financial markets. We focus on economies with nominal rigidities in goods and labor markets and subject to constraints on monetary policy, such as the zero lower bound or fixed exchange rates. We identify an aggregate...

I analyze whether banks are efficient at allocating resources across intermediation activities. Competition between lenders means that resources are needed to draw borrowers into credit matches. At the same time, imperfect information between lenders and borrowers means that resources are also...

We present a model in which managers are risk-averse and firms compete for scarce managerial talent ("alpha"). When managers are not mobile across firms, firms provide efficient compensation, which allows for learning about managerial talent and for insurance of low-quality managers. When...

While the direct effect of lender-of-last-resort (LOLR) facilities is to forestall the default of financial firms that lose funding liquidity, an indirect effect is to allow these firms to minimize deleveraging sales of illiquid assets. This unintended consequence of LOLR facilities manifests...

In many cultures and industries gifts are given in order to influence the recipient, often at the expense of a third party. Examples include business gifts of firms and lobbyists. In a series of experiments, we show that, even without incentive or informational effects, small gifts strongly...

The interaction between credit frictions, financial innovation, and a switch from optimistic to pessimistic beliefs played a central role in the 2008 financial crisis. This paper develops a quantitative general equilibrium framework in which this interaction drives the financial amplification...

A principal reason that losses from catastrophic risks have been increasing over time is that more individuals and firms are locating in harm's way while not taking appropriate protective measures. Several behavioural biases lead decision-makers not to invest in adaptation measures until after...
