In a 1-year randomized controlled trial involving thousands of university students, we provide real-time private feedback on relative performance in a semester-long online assignment. Within this setup, our experimental design cleanly identifies the behavioral response to rank incentives (i.e.,...

This paper studies the dynamic behavior of asset prices using a chartist - fundamentalist model with two speculative markets. To this effect, we employ a differential system with delays similar to Dibeh (2007) to describe the price dynamics and we assume that the two markets are coupled via...

The time evolution of prices and savings in a stock market is modeled by a discrete-delay nonlinear dynamic system. The proposed model has a unique and unstable steady-state, so its time evolution is determined by the nonlinear effects acting out of the equilibrium. We perform the analysis of...

This paper studies a mechanism-design problem involving a principal-supervisor-agent in which collusion between supervisor and agent can only occur after they have decided to participate in the mechanism. We show how collusion can be eliminated at no cost via the use of a mechanism in which the...
