Using the Leontief inverse matrix derived from Chilean Central Bank input-output tables of the System of National Account we calculated the amount of labor directly and indirectly required to produce one physical unit of each commodity. If the share of various items in total consumption is used...

We analyze the pitfalls involved in VAR based return decompositions. First, we show that recent criticism of such decompositions is misplaced and builds on invalid VAR models and erroneous interpretations. Second, we explain the requirements needed for VAR decompositions to be valid. A crucial -...

When close equals groups are used for decomposing the redistributive effect of taxation, it arises the issue related to the choice of a proper bandwidth. Recent literature (Kim and Lambert, 2008; Urban and Lambert, 2008) suggests to set the bandwidth for close equals groups to maximize the vertical...

We consider the problem of finding the minimum of a real-valued multivariate polynomial function constrained in a compact set defined by polynomial inequalities and equalities. This problem, called polynomial optimization problem (POP), is generally nonconvex and has been of growing interest to...

We consider polynomial optimization problems pervaded by a sparsity pattern. It has been shown in [1, 2] that the optimal solution of a polynomial programming problem with structured sparsity can be computed by solving a series of semidefinite relaxations that possess the same kind of sparsity....
