vertical foreclosure with the choice of Input specifications
The RAND Journal of Economics, 2000Co-Authors: Jay Pil ChoiAbstract:We develop an equilibrium model of vertical foreclosure with the choice of Input specifications. Vertical foreclosure occurs as the upstream division of the integrated firm makes a specialized Input for its sister downstream division while it would, as an independent firm, provide a Generalized Input. The changes in incentives with vertical integration can be explained by the externalities the choice of a specialized Input entails; vertical integration allows the upstream firm to internalize the benefit of raising the rival firm's costs at the downstream level. We derive conditions for equilibrium vertical foreclosure to occur and discuss its welfare consequences.

Energy requirements of households in Brazil
Energy Policy, 2005Co-Authors: Claude Cohen, Manfred Lenzen, Roberto SchaefferAbstract:Abstract In this study we determine the total (direct plus indirect) energy requirements of a given set of Brazilian households. We use a Generalized Input–output model in order to calculate the energy embodied in goods and services purchased by households of different income level in 11 capital cities of Brazil. Our results show that, on average, the total energy intensity of household expenditure increases with income level, although there is a considerable spread in energy intensities within income classes as well as disparities between regions of the country. The total yearly average energy requirement per household in Brazil in 1995–96 was 173.6 GJ (61% of which was indirect), with 32.8 GJ for the lower income level (66% of which was indirect), and 602.2 GJ for the higher income level (62% of which was indirect). Of this total average energy requirement, 76% was required for only three consumption categories: utilities (31%), mobility (28%) and shelter (17%). This analysis calls for the attention that has to be given not only to the direct energy consumption (as motor fuels and electricity, for example) but also to the consumption categories that encompass an important part of the indirect energy requirement of households in capital cities in Brazil.

a Generalized Input output multiplier calculus for australia
Economic Systems Research, 2001Co-Authors: Manfred LenzenAbstract:A static, Generalized Input-output framework for calculating simple multipliers is presented for Australian data. In this framework, capital investment and imports are internalized into domestic inter-industrial intermediate demand, non-square matrices are introduced in order to enable the inclusion of finer detail commodity data, and matrices in both monetary and physical units are employed. A range of labour and energy multipliers are calculated, referring to total output, final demand, final consumption, basic values, producers' prices, purchasers' prices, commodities and industries. Uncertainties of multipliers are assessed in detail, using Monte Carlo simulations.

linearization by Generalized Input output injection
Systems & Control Letters, 1997Co-Authors: Franck Plestan, Alain GlumineauAbstract:Abstract The problem under interest is the linearization of nonlinear MIMO systems by Generalized Input-output injection in order to design observers with linear error dynamics. The method is based on the study of the structure of the Input-output differential equations; thus, the problem is solved as a realization problem. In this note, one considers the linearization under two kinds of inout-output injection. In the first case, the transformation depends on the output and time derivatives of the Input, whereas in the second case, derivatives of both the Input and the output are considered. Necessary and sufficient conditions are obtained which generalize the ones on standard Input-output injection linearization.

Generalized Input Impedance Modeling of TL-Network-Based HFDPS for Validating Frequency-Dependent Criteria for Power-Signal Integrity
IEEE Transactions on Industrial Electronics, 2018Co-Authors: Ankit Gupta, Nikhil Kumar, Sudip K. MazumderAbstract:Adjusting the transmission-line (TL) length or using active compensation is pursued in high-frequency-distributed power systems (HFDPSs) as a possible remedy for addressing the TL effects. Although adjusting the TL length is primarily limited to printed-circuit-board (PCB) level implementations, active compensation yields higher expense and complexity. To mitigate TL effects under periodic condition, Generalized Input impedance modeling of a TL-network-based HFDPS feeding linear load(s) is provided. Using this Generalized model, a frequency-dependent criterion for maintaining power-signal integrity is outlined for scenario centric single-/multiple-Input single-/multiple-output HFDPS topologies. Selection of such a transmission frequency is important for designing a HFDPS to avoid deterioration of voltage and current, rupturing the TL insulation, and increased losses owing to the TL effect. Validations of the frequency-dependent criteria have been carried out using simulation and experiments in time and frequency domains.
