The present study is to indicate that the comparison between sectoral production multipliers of an input-output (I/O) model and a social accounting matrix (SAM) framework is almost impossible without taking into account accounting balances and theoretical considerations. Theoretically, the I/O model provides the Leontief’s production function, on the basis of which sectoral output multiplier ca...

The objective of this paper is to present a way to incorporate sectoral structure within the measures of regional growth provided by the traditional shift-share analysis. The new tool makes it possible to considerer in the decomposition analysis three new effects: sectoral national effect, sectoral structural effect, and sectoral differential effect. To illustrate the analysis of sectoral struc...

background: leishmaniasis is an obligate intercellular protozoon that affects animals and human. it has zoonosis and/or anthroponosis transmission. human and veterinary medicine, environmental science and wildlife conservation special­ists have many commonalities in case of visceral leishmaniasis. still the above disciplines respond against leishmaniasis in a separate way.   the aim of this re­...

Twelve kinds of special semipositive matrices and their basic characters are presented. Employing these matrices and the previous results in Zeng (2008), we research the conditions for the balances between final output values and values-added, and between input multipliers and output multipliers in an economy. A necessary and sufficient condition that (i) there exists a unique vector of output ...

Price changes and output growth, both at the aggregate and the sectoral level, appear to be negatively correlated. At a basic level, this suggests that sectoral “supply” shocks are more prevalent than sectoral “demand” shocks. However, it is not clear what these sectoral price-output correlations mean once one thinks in terms of general equilibrium. To help us understand the implication of thes...

The sectoral structure of most agricultural enterprises is unbalanced and uncoordinated, which underlies the need in deepened research of its improvement. This paper is dedicated to the formation and evaluation of the sectoral structure with the use of mathematical methods of data processing. Mathematical economic modeling based on optimization and simulation models has been applied for the for...

Working papers are preliminary documents circulated to stimulate discussion and obtain comments The Sectoral Activities Department is part of the Social Dialogue Sector of the ILO. Its objective is to promote social dialogue at the sectoral level and to facilitate the exchange of information among the ILO's constituents on labour and social developments concerning particular economic sectors. O...

This paper examine Lilien’s sectoral shifts hypothesis for Japan for different age cohorts. Previous studies of the sectoral shifts hypothesis for Japan have for the most part concentrated on the relationship between aggregate unemployment and sectoral shifts, and are typically not supportive of the hypothesis. However, recent increases in the unemployment rates of the young and the aged sugges...

We examine the relationship between market structure and the persistence of US dollar-based sectoral real exchange rates for 14 OECD countries. Our empirical results based on disaggregated data suggest that differences in market structure significantly determine the rates at which deviations from sectoral purchasing power parity decay. Specifically, industries with a larger price-cost margin ar...

A multisectoral global model was constructed on a 35 I-O sectoral basis in 1995 and has extensively been used for various policy analyses. The model, EITF, covers 29 countries and 7 regions with special reference to G7 and Asian countries. World trade can also be analyzed in the same sectoral categories, enabling the analysis of significant changes in foreign trade consistent with those for sec...
