The paper presents a new method to solve DSGE models with a great number of heterogeneous agents. Using tools from systems and control theory, it is shown how to reduce the dimension of the state and the policy vector so that the reduced model approximates the original model with high precision....

For many years information security and risk management has been an art rather than a science. This has resulted in the reliance on experts whose methodologies and results can vary widely and which have led to the growth of fear, uncertainty and doubt within the community. At the same time, the...

Privacy remains an intractable ethical issue for the information society. Given its complicity, there is a moral obligation to redress privacy issues in systems engineering practice itself. This paper investigates the role the concept of privacy plays in contemporary systems engineering...
