The use of constant price Input-Output (I-O) models is based on a widely accepted ex-ante notion without a strong empirical analysis. The present paper contributes by filling the research gap with regards to a comparison of nominal and real technology coefficients of India for the latest year...

Increasing interaction between economic growth and its environmental implications requires a more focused study of energy linkages. This paper is an attempt to trace changing energy linkages in an I-O framework using widely accepted concepts of backward and forward linkages. It differs from...

The increasing importance of global supply chains has prompted the use of analytical tools based on trade in value added – instead of traditional measures in gross value. We use this analytical framework to develop indicators that identify hubs and spokes in international supply chains. Using...

This paper is an attempt to analyze changing energy intensities in the Indian economy. The hybrid I-O model at constant prices has been used to address the problem of homogenous pricing of energy inputs across sectors of the economy. Results reveal that the indirect rather than direct energy use...

The paper studies topological properties of weighted directed graphs corresponding to highly aggregated macroeconomic input-output networks in Russia and the USA. As these graphs are complete or almost complete the study focuses on weight-sensitive characteristics of weighted directed networks....

The input-ouput model remains the basis of most SAM or CGE models. It actually uses two periods: the prices indexes solve it with the current period coefficients; the corresponding physical model is monoperiodic: the current prices solve it with the base period coefficients. The Leontief model...

Natural and anthropogenic disasters frequently affect both the supply and demand side of an economy. A striking recent example is the COVID-19 pandemic which has created severe industry-specific disruptions to economic output in most countries. Since firms are embedded in production networks,...

Economic shocks due to COVID-19 were exceptional in their severity, suddenness and heterogeneity across industries. To study the upstream and downstream propagation of these industry-specific demand and supply shocks, we build a dynamic input-output model inspired by previous work on the...

The exploration of the structural features and sectoral interdependences of and in an economy is fundamental for the understanding of its modes of functioning and of its transformations over time. Input-output analysis is largely used to fulfill this objective. Furthermore, information provided...
