Andrea Attar, Catherine Casamatta, Arnold Chassagnon, and Jean-Paul Décamps, “Multiple Lenders, Strategic Default and the Role of Debt Covenants”, American Economic Journal: Microeconomics, vol. 11, n. 2, May 2019, pp. 98–130.

We study capital markets subject to moral hazard when investors cannot prevent side trading, thereby facing an externality if firms raise funds from multiple sources. We analyze whether investors’ ability to design financial covenants that may include exclusivity clauses mitigates this externality...

Helmuth Cremer, and Kerstin Roeder, “Income taxation of couples, spouses' labor supplies and the gender wage gap”, Economics Letters, vol. 175, February 2019, pp. 71–75.

We study the taxation of couples when female wages do not re?ect their true productivity. We show that the expression for the marginal tax rates of the male spouses is the same as in a Mirrleesian world where wages re?ect true productivities. Marginal taxes for the female spouses are reduced...

Bruno Jullien, Markus Reisinger, and Patrick Rey, “Vertical Foreclosure and Multi-Segment Competition”, Economics Letters, vol. 169, August 2018, pp. 31–34.

This paper analyzes a supplier's incentives to foreclose downstream entry when entrants have stronger positions in different market segments, thus bringing added value as well as competition. We first consider the case where wholesale contracts take the form of linear tariffs, and characterize the...

Marc Bourreau, and Bruno Jullien, “Mergers, investments and demand expansion”, Economics Letters, vol. 167, June 2018, pp. 136–141.

In this paper, we study the impact of a merger to monopoly on prices and investments. Two single-product firms compete in prices and coverage for a new technology. In equilibrium, one firm covers a larger territory than its competitor with the new technology, leading to singleproduct and multi-...

Jean-Paul Décamps, and Stéphane Villeneuve, “Jusqu'où les compagnies d'assurance peuvent-elles investir dans le financement des dettes des PME/ETI ? : How Far Can Insurance Companies Invest in SMEs Debt Financing?”, Revue d'économie financière, n. 126, 2017, pp. 231–240.

Under the combined effects of a decline in rates and the political desire to help finance the economy within a regulatory environment that is restrictive for banks, since 2012 the law has authorized insurance companies, under certain conditions, to allocate up to 5% of their clients’ savings to the...

Helmuth Cremer, and Kerstin Roeder, “Rotten spouses, family transfers and public goods”, Journal of Population Economics, vol. 30, 2017, pp. 141–161.

We show that once interfamily exchanges are considered, Becker?s rotten kids mechan- ism has some remarkable implications that have gone hitherto unnoticed. Specifically, we establish that Cornes and Silva's (1999) result of e¢fficiency in the contribution game amongst siblings extends to a setting...

Sébastien Pouget, Julien Sauvagnat, and Stéphane Villeneuve, “A Mind is a Terrible Thing to Change: Confirmation Bias in Financial Markets”, The Review of Financial Studies, vol. 30, n. 6, June 2017, pp. 2066–2109.

This paper proposes a dynamic model of financial markets where some investors are prone to the confirmation bias. Following insights from the psychological literature, these agents are assumed to amplify signals that are consistent with their prior views. In a model with public information only,...

Matthew Adler, David Anthoff, Valentina Bosetti, Greg Garner, Klaus Keller, and Nicolas Treich, “Priority for the worse-off and the social cost of carbon”, Nature Climate Change, May 2017, pp. 443–449.

The social cost of carbon (SCC) is a key tool in climate policy. The SCC expresses in monetary terms the social impact of the emission of a ton of CO2 in a given year. The SCC is calculated using a ‘social welfare function’ (SWF): a method for assessing social welfare. The dominant SWF in climate...

External Constraints and Endogenous Growth: Why didn't Some Countries Benefit from Capital Inflows? (1)

Paul Woolley Research Initiative Seminar (1)

IDEI

The aim of this seminar is bring together researchers to discuss recent papers dealing with several aspects of market dysfunctionalities, such as, e.g., illiquidity, manipulations, or cascades. The papers study how information asymmetries, market power, and irrationality can give rise to such...

Expectations with Endogenous Information Acquisition: An Experimental Investigation (1)

Mirko Wiederholt (Sciences Po - Paris)

TSE, March 11, 2019, 17:00–18:30, room MF 323

Information frictions play an important role in many theories of expectation formation and macroeconomic fluctuations. We use a survey experiment to generate direct evidence on how people acquire and process information. Participants can buy different information signals that could help them...

Optimal Bank Regulation - In the Presence of Credit and Run Risk (1)

Dimitrios Tsomocos (Saïd Business School - University of Oxford)

Toulouse: TSE, March 11, 2019, 12:30–14:00, room MF 323

We modify the Diamond and Dybvig (1983) model of banking to jointly study various regulations in the presence of credit and run risk. Banks choose between liquid and illiquid assets on the asset side, and between deposits and equity on the liability side. The endogenously determined asset portfolio...

CAPM-Based Company (Mis)valuations (1)

Olivier Dessaint (Rotman School of Management - University of Toronto)

TSE, December 17, 2018, 12:30–14:00, room MF 323

There is a discrepancy between CAPM-implied and realized returns. Using the CAPM in capital budgeting { as recommended in finance textbooks { should thus have valuation effects. For instance, low beta projects should be valued more by CAPM-using managers than by the market. This paper empirically...

Liquidity Creation as Volatility Risk (1)

Alan Moreira (University of Rochester - Simon Business School)

TSE, December 10, 2018, 12:30–14:00, room MF 323

We show, both theoretically and empirically, that liquidity creation induces negative exposure to volatility risk. Intuitively, liquidity creation involves taking positions that can be exploited by privately informed investors. These investors’ ability to predict future price changes makes their...
