Decomposing Bjurek Productivity Indexes into Explanatory Factors

Decomposing Value Added Growth over Sectors into Explanatory Factors

A decomposition of nominal value added growth over multiple sectors of an economy into explanatory factors is presented. The explanatory factors over a single sector are changes in the efficiency of the sector, growth of primary inputs, changes in sectoral output and input prices, technical progress and returns to scale. In order to implement the decomposition for a sector, an estimate of the s...

Aggregation of Malmquist productivity indexes

In this paper we extend the work of Färe and Zelenyuk (2003) to find a theoretically justified method of aggregating Malmquist Productivity Indexes over individual decision making units (firms, countries, etc.) into a group Malmquist Productivity Index. We also consider the aggregation of decomposed parts of the Malmquist Productivity Index to obtain a decomposition of the Malmquist Productivit...

Decomposing 4-Regular Graphs into Triangle-Free 2-Factors

There is a polynomial algorithm which finds a decomposition of any given 4-regular graph into two triangle-free 2-factors or shows that such a decomposition does not exist.

Decomposing Matrices into Blocks

In this paper we investigate whether matrices arising from linear or integer programming problems can be decomposed into so-called bordered block diagonal form. More precisely, given some matrix A, we try to assign as many rows as possible to some number β of blocks of size κ such that no two rows assigned to different blocks intersect in a common column. Bordered block diagonal form is desirab...
