This paper presents econometric evidence of two independent effects of adding more competitors on innovation: 1) a competition effect whereby increasing rivalry shapes, and often decreases, incentives...
The Value of Openness in Scientific Problem Solving
Scientific information sharing amongst scientists
2015/4/21
Openness and free information sharing amongst scientists are supposed to be core norms of the scientific community. However, many studies have shown that these norms are not universally followed. Lack...
Macaulay's problem
economic man “as if” explanations apriorism rational choice methodology of economics empirical content of theories
2014/6/23
The model of economic man is either empirically testable and false, or it is non-testable and always true. The fact that neither position is entirely satisfactory is called Macaulay’s problem. This pa...

A control problem with fuel constraint and Dawson-Watanabe superprocesses
Dawson-Watanabe superprocess J-functional log-Laplace equation optimal sto-chastic control with fuel constraint optimal order execution
2012/9/14
We solve a class of control problems with fuel constraint by means of the log-Laplace trans-forms of J-functionals of Dawson–Watanabe superprocesses. This solution is related to the superprocess solut...

We illustrate a problem in the self-financing condition used in the papers “Fund-ing beyond discounting: collateral agreements and derivatives pricing” (Risk Magazine,February 2010) and “Partial Diffe...
On the Exact Solution of the Multi-Period Portfolio Choice Problem for an Exponential Utility under Return Predictability
multi-period asset allocation expected utility optimization exponential utility func-tion return predictability.
2012/9/14
In this paper we derive the exact solution of the multi-period portfolio choice problem for an exponential utility function under return predictability. It is assumed that the asset returns depend on ...
A Closed-Form Solution of the Multi-Period Portfolio Choice Problem for a Quadratic Utility Function
multi-period asset allocation quadratic utility function closed-form solution tan-gency portfolio
2012/9/14
In the present paper, we derive a closed-form solution of the multi-period portfolio choice problem for a quadratic utility function with and without a riskless asset. All results are derived under we...
Numerical methods for the quadratic hedging problem in Markov models with jumps
Quadratic hedging Hamilton-Jacobi-Bellman equation Markov jump processes Par-tial integro-di erential equation Holder spaces electricity markets discretization schemes for PIDE.
2012/9/14
We develop algorithms for the numerical computation of the quadratic hedging strategy in incomplete markets modeled by pure jump Markov process. Using the Hamilton-Jacobi-Bellman approach, the value f...
