Some Alternative Psd Policies

Some upper and lower bounds on PSD-rank

Positive semidefinite rank (PSD-rank) is a relatively new quantity with applications to combinatorial optimization and communication complexity. We first study several basic properties of PSD-rank, and then develop new techniques for showing lower bounds on the PSD-rank. All of these bounds are based on viewing a positive semidefinite factorization of a matrix M as a quantum communication proto...

Control Policies for some Continuous -

In some industries, it is preferable to use control policies to schedule production. Starting from any connguration of the stocks, an optimal control policy leads the surplus level to a stationary state. The goal of this paper is to provide some control policies for a continuous-time production scheduling problem where demand is constant. For a one machine and multi-item case, we develop a cont...

Alternative Monetary Policies in a Turnpike Economy*

A version of a Townsend turnpike model is described in which agents stay at a location long enough to trade some consumption loans, but not long enough to support an Arrow-Debreu allocation. Monetary equilibria exist which are non-optimal in the absence of a scheme to pay interest on currency at a particular rate. Paying interest on currency at the optimal rate delivers a Pareto optimal allocat...

Alternative Pollution Control Policies in Developing Countries

After decades of rapid urbanization, population growth, and industrialization, developing countries are now home to many of the world’s most severe air, water, and solid waste pollution problems. Most are taking action to address these problems, relying principally on conventional command-and-control (CAC) approaches, such as mandatory emissions limits and technology standards. Although some co...
