A Dynamic Model of Input–Output Networks
Review of Economic StudiesAbstract We develop a dynamic model of input–output networks that incorporates adjustment costs of changing inputs. Our closed-form solution for the dynamics of the economy shows that temporary shocks to upstream sectors, whose output travels through long supply chains, have disproportionately significant welfare impact compared to ...

Fuzzy dynamic input–output inoperability model
International Journal of Critical Infrastructure Protection, 2011Abstract This paper describes an extension of the input–output inoperability model (IIM) that accommodates uncertain and vague data. In the resulting “fuzzy version” of the dynamic IIM model (FD-IIM), the level of inoperability of each infrastructure and the Leontief coefficients are specified using fuzzy variables that express expert knowledge about

A Robust MPC for Input-Output LPV Models
IEEE Transactions on Automatic Control, 2016In this note, a discrete-time robust model predictive control (MPC) design approach is proposed to control systems described by linear parameter-varying models in input-output form subject to constraints. To ensure the stability of the closedloop system, a quadratic terminal cost along with an ellipsoidal terminal constraint are included in the control

Input-output is a conceptualization of the interdependence of economic production units that has come to be used over the years both as a modeling device and as an element in national economic accounting systems. The input-output (I-O) framework as such, cannot be employed directly to model mineral and energy market behavior. However, it does provide a

Agent-based input–output interdependency model
International Journal of Critical Infrastructure Protection, 2010Abstract The modeling and analysis of critical infrastructures and their interdependencies are essential to discovering hidden vulnerabilities and the related threats to national and international security. Over the past few years, several approaches have been proposed to address this problem. The so-called holistic approaches are relatively abstract,

Taxes and Subsidies in the Input-Output Model
The Quarterly Journal of Economics, 1981This paper reexamines Metzler's analysis of the effects of taxes and subsidies on the competitive supply prices of output in Leontiefs system. It will be shown that Metzler's conclusions are valid even if one removes the assumptions made by Metzler, and that Allen's conclusion concerning the ad valorem tax is false.

The Brain as an Input–Output Model of the World
Minds and Machines, 2017An underlying assumption in computational approaches in cognitive and brain sciences is that the nervous system is an input–output model of the world: Its input–output functions mirror certain relations in the target domains. I argue that the input–output modelling assumption plays distinct methodological and explanatory roles.
