Social comparison and effort provision: evidence from a field experiment

Social comparison processes have potentially far reaching consequences for many economic domains. We conducted a randomized field experiment to examine how social comparison affects workers’ effort provision if their own wage or the wage of a co‐worker is cut. Workers were assigned to groups of two, performed identical individual tasks, and received the same performanceindependent...

Hazardous times for monetary policy: What do twenty-three million bank loans say about the effects of monetary policy on credit risk?

We identify the effects of monetary policy on bank risk-taking with an exhaustive credit register containing loan contracts and applications since 1984. We separate the compositional changes in the credit supply from the demand, firm and bank balance-sheet channels by accounting for both observed and unobserved time-varying firm and bank heterogeneity through time*firm and time*bank...

Optimal dividend policy with random interest rates

Several recent papers have studied the impact of macroeconomic shocks on the financial policies of firms. However, they only consider the case where these macroeconomic shocks affect the profitability of firms but not the financial markets conditions. We study the polar case where the profitability of firms is stationary, but interest rates and issuance costs are governed by an...

R&D networks: theory, empirics and policy implications

We study a structural model of R&D alliance networks in which firms jointly form R&D collaborations to lower their production costs while competing on the product market. We derive the Nash equilibrium of this game, provide a welfare analysis and determine the optimal R&D subsidy program that maximizes total welfare. We also identify the key firms, i.e. the firms whose...

Mixed equilibria in Tullock contests

Any symmetric mixed-strategy equilibrium in a Tullock contest with intermediate values of the decisiveness parameter ("2 < R < ∞") has countably infinitely many mass points. All probability weight is concentrated on those mass points, which have the zero bid as their sole point of accumulation. With contestants randomizing over a non-convex set, there is a cost of...

God does not play dice, but people should: random selection in politics, science and society

This paper discusses and proposes random selection as a component in decision-making in society. Random procedures have played a significant role in history, especially in classical Greece and the medieval city-states of Italy. We examine the important positive features of decisions by random Mechanisms. Random processes allow representativeness with respect to individuals and groups...

Risk sharing with the monarch: contingent debt and excusable defaults in the age of Philip II, 1556–1598

Contingent sovereign debt can create important welfare gains. Nonetheless, there is almost no issuance today. Using hand-collected archival data, we examine the first known case of large-scale use of state-contingent sovereign debt in history. Philip II of Spain entered into hundreds of contracts whose value and due date depended on verifiable, exogenous events such as the arrival of...

Recreating the south sea bubble: lessons from an experiment in financial history

Major bubble episodes are rare events. In this paper, we examine what factors might cause some asset price bubbles to become very large. We recreate, in a laboratory setting, some of the specific institutional features investors in the South Sea Company faced in 1720. Several factors have been proposed as potentially contributing to one of the greatest periods of asset overvaluation...

Leverage and beliefs: personal experience and risk taking in margin lending

What determines risk-bearing capacity and the amount of leverage in financial markets? Using unique archival data on collateralized lending, we show that personal experience can affect individual risk-taking and aggregate leverage. When an investor syndicate speculating in Amsterdam in 1772 went bankrupt, many lenders were exposed. In the end, none of them actually lost money....

Does money illusion matter?: Reply

The data in Fehr and Tyran (FT, 2001) and Luba Petersen and Abel Winn (PW,2013) show that money illusion plays an important role in nominal price adjustment after a fully anticipated negative monetary shock. Money Illusion affects subjects' expectations, and causes pronounced nominal inertia after a negative shock but much less inertia after a positive shock. Thus PW provide a...

Cyclical fiscal policy, credit constraints, and industry growth

What are the effects of cyclical fiscal policy on industry growth? We show that industries with a relatively heavier reliance on external finance or lower asset tangibility tend to grow faster (in terms of both value added and of labor productivity growth) in countries that implement fiscal policies that are more countercyclical. We reach this conclusion using Rajan and Zingales׳s (...

Organizing corruption controls after a scandal: Regaining legitimacy in complex and changing institutional environments

We study the corruption control strategies at three Multinational companies (MNC) before, during, and after the disclosure of corruption scandals and the initiation of legal procedures. In particular, we want to explore why some MNCs after a corruption scandal exceed regulatory expectations, choose proactive strategies, and influence their environment as institutional entrepreneurs...

Lending to the borrower from hell: Debt, taxes, and default in the age of Philip II

As the United States and many European nations struggle with mountains of debt, historical precedents can offer valuable insights. Lending to the Borrower from Hell looks at one famous case - the debts and defaults of Philip II of Spain. Ruling over one of the...

Rethinking the regulatory treatment of securitization

In a model where banks play an active role in monitoring borrowers, we analyze the impact of securitization on bankers’ incentives across different macroeconomic scenarios. We show that securitization can be part of the optimal financing scheme for banks, provided banks retain an equity tranche in the sold loans to maintain proper incentives. In economic downturns however...
