SPATIAL AGGREGATION BIAS OF REGIONAL INPUT-OUTPUT ANALYSES

ENVIRONMENTAL IMPACTS OF ENERGY-EFFICIENT TECHNOLOGIES: POTENTIAL FOR INPUT-OUTPUT AND SUPPLY-CHAIN ANALYSES IN IRAN

The effect of imports on employment in Ilam province (two regional input-output approach)

The aim of this study was to investigate the effect of imports on employment in Ilam province and to analyze the Explicit and implicit aspects of unemployment by non-statistical method in this province. For this purpose, a two regional input-output table of 2016 in the form of 11 sectors and two regions of Ilam province and the rest of national economy has been made and this effect has been mea...

Impact of Spatial Soil and Climate Input Data Aggregation on Regional Yield Simulations

We show the error in water-limited yields simulated by crop models which is associated with spatially aggregated soil and climate input data. Crop simulations at large scales (regional, national, continental) frequently use input data of low resolution. Therefore, climate and soil data are often generated via averaging and sampling by area majority. This may bias simulated yields at large scale...

Aggregation in Macroeconomic Models: An Empirical Input-Output Approach

The aggregation level of industries in the Danish macroeconomic model ADAM is examined using a new indicator of aggregation bias. The indicator is decomposed into contributions from the original industries, thereby clearly identifying the aggregation problems which caused the 6 industry groups of the older versions of ADAM to be disaggregated into the current 19 groups. An aggregation key minim...

Enhance parallel input/output with cross-bundle aggregation

The exponential growth of computing power on leadership scale computing platforms imposes grand challenge to scientific applications’ input/output (I/O) performance. To bridge the performance gap between computation and I/O, various parallel I/O libraries have been developed and adopted by computer scientists. These libraries enhance the I/O parallelism by allowing multiple processes to concurr...
