Solvability of the Economic Input-Output Equation by Time Irreversibility  [PDF]
Shinji Miura
Advances in Linear Algebra & Matrix Theory (ALAMT) , 2014, DOI: 10.4236/alamt.2014.43013
This paper reinterprets the economic input-output equation as a description of a realized situation without considering decision making. This paper uses the equation that the self-sufficiency rate is added to the Leontief type, and discusses its solvability. The equation has a unique solution if and only if each part of the relevant society satisfies the space-time openness condition. This condition means that commodities which a part of the relevant society possesses are not all inputted to its inside. Moreover, if the process of input and output is time irreversible, each part of the relevant society satisfies the space-time openness condition. Therefore, the solvability of the equation is guaranteed by time irreversibility. This proposition seems to be relevant to the grandfather paradox which is a type of time paradox.
Assessing the Impacts of Final Demand on CO2-eq Emissions in the Mexican Economy: An Input-Output Analysis  [PDF]
Diego Chatellier-Lorentzen, Claudia Sheinbaum-Pardo
Energy and Power Engineering (EPE) , 2017, DOI: 10.4236/epe.2017.91004
Abstract: The aim of this paper is to analyze the Mexican energy system and its greenhouse gas (GHG) emissions for the year 2012 and to estimate a baseline scenario for 2026 using an input-output analysis. The elasticity of emissions with respect to national demand is calculated in order to identify the total and distributed effects of CO2 equivalent (CO2-eq) emissions. In this framework, the analysis evaluates the effects in the economy related to changes in individual sector demands, and, vice versa, the effect on individual sectors due to global changes in national demands. Results show that passenger and freight transport, power generation, iron and steel industry, chemical industry, air transportation and agriculture concentrate the largest potential for mitigation strategies, and also have important distributive effects on the Mexican economy. Results are evaluated under the mitigation strategies of industrial sector proposed by the Fifth Assessment Report of the IPCC.
A New Approach to Compute the Cross-Gramian Matrix and its Application in Input-Output Pairing of Linear Multivariable Plants
B. Moaveni,A. Khaki-Sedigh
Journal of Applied Sciences , 2008,
Abstract: In this study, a new approach to solve the Sylvester equation, AX+XA = -BC is derived. The calculated cross-Gramian matrix, which results from the Sylvester equation, proposes a new input-output pairing analysis for stable multivariable plants. This new approach is based on the cross-Gramian matrix of SISO elementary subsystems built from the original MIMO plant and the main advantage of the method is its simplicity to choose the best input-output pair, though, it considers the plant dynamic properties.
Aplicación de la teoría de grafos al análisis input-output: Andalucía 1995
Flor María Guerrero Casas,José Antonio Ordaz Sanz
Rect@ , 2000,
Abstract: La Economía Aplicada contemporánea resultaría impensable sin el análisis input-output, por su contribución decisiva al conocimiento de las actividades económicas de los países y a la armonización de sus cuentas. Muchas de las políticas sociales y económicas que se llevan a cabo en nuestros días residen en sus fundamentos, y su aplicación resulta esencial en infinidad de campos: contabilidad nacional y regional, comercio, empleo, desarrollo tecnológico, medio ambiente, ... Las Tablas Input-Output de Andalucía de 1995 constituyen un buen exponente actual de la preocupación de los poderes públicos por conocer con el mayor detalle posible la realidad de la actividad económica de sus ámbitos territoriales, lo que contribuye en gran medida a facilitar la toma de decisiones. El análisis matricial y el establecimiento de condiciones destinadas a asegurar la resolución de sistemas de ecuaciones lineales de soluciones no negativas conforman, sin lugar a dudas, la base sobre la que se ha desarrollado el modelo input-output. Sin embargo, no tienen por qué ser la única. La Teoría de grafos se está revelando de forma creciente como una herramienta cada vez más útil en el estudio de problemas de carácter económico, siendo precisamente las tablas input-output uno de los principales ejemplos de ello.
A New Model for AS-AD Analysis Based on Input-Output Frame  [PDF]
Xinjian Liu
Modern Economy (ME) , 2011, DOI: 10.4236/me.2011.23026
Abstract: This paper has established a new kind of AS-AD models with input-output techniques. The models take the standard input-output tables as its starting points. We analyze the change effects of government consumption, direct consumption coefficient, labor productivity, and surplus rate on the equilibrium output. In this paper, we propose that the aggregate demand function curve should be right upward, and this lead to a series of inconsistent conclusions with the traditional views. Finally, we also analyze the well-known issue of stagflation.
Application of Linear Model Predictive Control and Input-Output Linearization to Constrained Control of 3D Cable Robots  [PDF]
Ali Ghasemi
Modern Mechanical Engineering (MME) , 2011, DOI: 10.4236/mme.2011.12009
Abstract: Cable robots are structurally the same as parallel robots but with the basic difference that cables can only pull the platform and cannot push it. This feature makes control of cable robots a lot more challenging compared to parallel robots. This paper introduces a controller for cable robots under force constraint. The controller is based on input-output linearization and linear model predictive control. Performance of input-output linearizing (IOL) controllers suffers due to constraints on input and output variables. This problem is successfully tackled by augmenting IOL controllers with linear model predictive controller (LMPC). The effecttiveness of the proposed method is illustrated by numerical simulation.
A Generalization of the Input-Output Pollution Control Model and Product Selection  [PDF]
Aniekan Ebiefung
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.42055

The input-output pollution control model given in [1] is generalized. The generalization makes it easier for the model to handle many problem instances. A linear program is used to solve the new model. An example is given to show that the new model can handle classes of problems that the original model cannot handle.

Analyzing the Role of Creative Industries in National Economy of Japan: 1995-2005  [PDF]
Ubaidillah Zuhdi
Open Journal of Applied Sciences (OJAppS) , 2014, DOI: 10.4236/ojapps.2014.44020
Abstract: The purposes of this study are 1) to get another perspective related to the role of creative industries in national economy of Japan from 1995-2005 and 2) to know the ways to improve these sectors. This study employs Input-Output (IO) analysis as a tool of analysis. More specifically, this study uses simple output multipliers and demand-pull IO quantity model. Comparison with previous study is conducted in order to achieve the first objective. Another perspective related to above role is obtained from this study, namely creative industries, using simple output multipliers method, did not have an important role in national economy of Japan in analysis period. The results also show that the patterns of total output of creative industries of Japan on future period are not identic. Nevertheless, these sectors have one similarity, namely the modification of import will decrease their total output. This phenomenon indicates that import restriction related to these sector’s products is needed.
The Industrial Relations of Logistics Industry—Based on China’s 2010 Input-Output Table  [PDF]
Jin Zhang, Lizhen Chen
Modern Economy (ME) , 2014, DOI: 10.4236/me.2014.512099

The paper explores the intrinsic link between logistics industry, national economy and three industries by using Chinese input-output table of 2010. It shows that logistics industry has the strongest inquiry and need on secondary industry; next is itself and the last is Agriculture. Second, the influence coefficient of logistics industry is after the second industry radiation ability; its status in national economy is strong and has become the dominant industry of national economic development. Furthermore, the degree of fluctuation for logistics industry is small, and its restriction role and bottleneck effect are obvious for national economy. Moreover, logistics industry is a sector with strong radiation and weak constraints and its promotion effect on national economy is more pronounced than that of national economy on itself.

The Comprehensive Economic Contribution of China’s Tourism Trade Export  [PDF]
Yi Liu, Wendi Li
Modern Economy (ME) , 2019, DOI: 10.4236/me.2019.104074
Abstract: International tourism trade plays an important role in earning foreign exchange through export. At the same time, this industry has a clear and single source of income, which enables relevant industrial policies to play a more effective guiding role. Thoroughly understanding the important role of China’s tourism export to economic growth, can help formulate industrial policies with theoretical basis and practical pertinence. However, there is still a lack of relevant research. In order to fill this gap, the author uses input-output analysis to calculate the comprehensive economic contribution of China’s tourism export, and its internal structure is analyzed. The results show that in 2016, the export of tourism trade achieved a direct added value of 317.658 billion yuan, and the complete added value driven by industrial spreading effect reached 796.734 billion yuan, accounting for 1.07% of GDP, which affirmed the strong economic pulling role of tourism export. According to the internal structure of complete added value, this paper suggests industrial policy should give priorities to support the development of tourism merchandise manufacturing, accommodation and catering sectors, guiding inbound tourists to increase the consumption in the above three items, so as to optimize the income structure and improve the comprehensive economic benefits of tourism trade export.
