ESTIMATION PROBLEMS IN MODELS WITH SPATIAL WEIGHTING MATRICES WHICH HAVE BLOCKS OF EQUAL ELEMENTS
SPATIAL WEIGHTING MATRICES HAVE BLOCKS EQUAL ELEMENTS
2015/9/24
Spatial models whose weighting matrices have blocks of equal elements might be considered if units are viewed as equally distant within certain neighborhoods, but unrelated between neighborhoods. We g...
Limited Access Orders in the Developing World: A New Approach to the Problems of Development
Industrial countries government monopoly
2015/9/22
The upper-income, advanced industrial countries of
the world today all have market economies with open
competition, competitive multi-party democratic
political systems, and a secure government mon...
Some Experimental Results on the Statistical Properties of Least Squares Estimates in Control Problems
Statistical Properties Control Problems
2015/8/5
The statistical properties of the certainty equivalence control rule and of the least squares
estimates generated by this rule are examined experimentally in a linear model with two
unknown paramete...

Envelope condition method versus endogenous grid method for solving dynamic programming problems
Hoover Institution, Stanford University, USA University of Alicante, Spain
2015/7/21
We introduce an envelope condition method (ECM) for solving dynamic programming problems. The ECM method is simple to implement, dominates conventional value function iteration and is comparable in ac...
Merging Simulation and Projection Aproaches to Solve High-Dimensional Problems with an Application to a New Keynesian model
Numerical algorithm dynamic economic model of the grid
2015/7/21
We introduce a numerical algorithm for solving dynamic economic models that merges stochastic simulation and projection approaches: we use simulation to approximate the ergodic measure of the solution...
Coordination and Cooperation Problems in Network Good Production
Social network formation coordination cooperation experiments collective goods
2014/11/27
If actors want to reach a particular goal, they are in many situations better off by forming collaborative relations and invest together rather than investing separately. In this paper we study the co...
Counting the World's Poor: Problems and Possible Solutions
the World's Poor Problems Possible Solutions
2014/3/18
As recent discussions have made clear, the apparent lack of poverty reduction in the face of historically high rates of economic growth-both in the world as a whole and in specific coun- tries (most n...

On the Equivalence of Quadratic Optimization Problems Commonly Used in Portfolio Theory
investment analysis mean-variance analysis parameter uncertainty interval estimation test theory.
2012/9/14
In the paper, we consider three quadratic optimization problems which are frequently applied in portfolio theory, i.e, the Markowitz mean-variance problem as well as the problems based on the mean-var...
C^{1,1} regularity for degenerate elliptic obstacle problems in mathematical finance
American-style option degenerate elliptic di erential operator degenerate di usion process, free boundary problem Heston stochastic volatility process mathematical nance obstacle problem variational inequality weighted Sobolev space.
2012/9/14
The Heston stochastic volatility process is a degenerate di usion process where the degeneracy in the di usion coecient is proportional to the square root of the distance to the boundary of the half-...
Stochastic representation of solutions to degenerate elliptic and parabolic boundary value and obstacle problems with Dirichlet boundary conditions
Degenerate elliptic and parabolic differential operators degenerate diffusion process Feller square root process Feynman-Kac formula
2012/4/28
We prove stochastic representation formulae for solutions to elliptic and parabolic boundary value and obstacle problems associated with a degenerate Markov diffusion process. In particular, our artic...
Cone-Constrained Continuous-Time Markowitz Problems
Markowitz problem cone constraints portfolio selection mean-variancehedging stochastic control semimartingales BSDEs martingale optimality principle opportunity process E-martingales linear-quadratic control
2012/9/14
The Markowitz problem consists of finding in a financial market a self-financing trading strategy whose final wealth has maximal mean and minimal variance. We
study this in continuous time in a gener...
The tragedy of the commons: property rights and markets as solutions to resource and environmental problems
bioeconomic models development economics economic growth
2011/10/23
In one way or another, all environmental and natural resource problems associated with overexploitation or under provision of public goods, arise from incompletely defined and enforced property rights...
