The Most Representative Composite Rank Ordering of Multi-Attribute Objects by the Particle Swarm Optimization

Mishra, Sudhanshu K. - 2009

Rank-ordering of individuals or objects on multiple criteria has many important practical applications. A reasonably representative composite rank ordering of multi-attribute objects/individuals or multi-dimensional points is often obtained by the Principal Component Analysis, although much...

A Note on Construction of Heuristically Optimal Pena’s Synthetic Indicators by the Particle Swarm Method of Global Optimization

Mishra, Sudhanshu K. - 2012

Pena's method of construction of a synthetic indicator is very sensitive to the order in which the constituent variables (whose linear aggregation yields the synthetic indicator) are arranged. Due to this, Pena's method can at present give only an arbitrary synthetic indicator whose...

Generalized Monotonicity Analysis

Strulovici, Bruno H. - 2008

Complex economic problems often lack the structure for the application of standard comparative statics techniques. Generalized Monotonicity Analysis (GMA) extends usual methods in several directions. First, it provides a new way of endogenously generating parameter moves that yield monotonicity....

Least Squares Estimation of Joint Production Functions By the Differential Evolution Method of Global Optimization

Mishra, Sudhanshu K. - 2007

In the economics of joint production one often distinguishes between the two cases: the one in which a firm produces multiple products each produced under separate production process, and the other "true joint production" where a number of outputs are produced from a single production process,...
