Spatial price comparisons rely to a high degree on the quality of the underlying price data that are collected within or across countries. Below the basic heading level, these price data often exhibit large gaps. Therefore, stochastic index number methods like the CPDmethod and the GEKS method...

Over the last three decades the supply of economic statistics has vastly improved. Unfortunately, statistics on regional price levels (sub-national purchasing power parities) have been exempt from this positive trend, even though they are indispensable for meaningful spatial comparisons of...

In this paper a new method of constructing the leading economic index is presented. Its main advantage is the ability to distinguish domestic and foreign factors influencing the growth of economy and it is performed via dynamic hierarchical factor modelling. An application is carried out with...

This short research article compiles and compares the research strength of various academic institutes, taking into consideration, various parameters. The paper gives statistical data on total research publications of those Institutes, till end of 2013

Statistical computing when input/output is driven by a Graphical User Interface is considered. A proposal is made for automatic control of computational flow to ensure that only strictly required computations are actually carried on. The computational flow is modeled by a directed graph for...

This document contains the first two chapters from my dissertation, titled Three Essays on Consumption and Geography, which use data provided by the Kilts Center for Marketing Data Center. Together they highlight the importance of accounting for geographic differences in new product entry to...

We estimate real consumption's growth rate and volatility in light of three new facts documenting geographic differences in consumption: (1) consumers in separate markets buy different products, (2) a product's market share varies geographically conditional on relative price, and (3) product...

This paper considers the problem of aggregation in the case of large linear dynamic panels, where each micro unit is potentially related to all other micro units, and where micro innovations are allowed to be cross sectionally dependent. Following Pesaran (2003), an optimal aggregate function is...
