Are Integration and Comparison Between CPIs and PPPs Feasible

The integration and comparison between the Consumer Price Indices (CPIs) and the Purchasing Power Parities (PPPs) has been widely discussed in literature and the need of a more integrated approach for calculating these indices has been emphasized. The paper focuses on these issues, both from a theoretical and practical point of view, suggesting the use of a broader definition of the comparability of products for the PPP calculation and a simple statistical method for investigating the advantages of broadening the definition of comparability to include additional products in the PPP calculation.

Evaluating the Efficiency of the Italian University Educational Processes through Frontier Production Methods

The university efficiency indicators, computed as partial indices following the input–output approach, are subject to criticism mainly concerning the problem of comparability of institutions due to the influence of several environmental factors. The aim of this study is to construct comparable efficiency indicators for the university educational processes by using frontier production methods which enable us to solve the problem. The indicators are computed for the Italian State Universities by using a new data set referring to the cohort of students enrolled in the academic year 2004/2005. A comparison with the corresponding partial indicators usually employed is presented.

Surveys: Critical Points, Challenges and Need for Development

The aim of this paper is to review some of the critical issues which need further insight in survey methodology and practice. The focus is on the specific aspects of the survey process grouping the main issues in the following three areas: (i) mode of collection of data and construct of questionnaire; (ii) sampling strategy, design and estimation, to reply to the demands of the users and integration of data; (iii) data dissemination and standardisation. For every issue survey data producers have to fight and ask for development.
