A sample of 76 firms that operate in the Internet is studied in order to explore forms of identifying and measuring intangible assets in this area of business. The firms meet three conditions: operate in the Internet, have available accounting information, and be quoted in the stock exchange....

This paper uses Data Envelopment Analysis (DEA), a non-parametric approach to the estimation of production functions, in order to assess efficiency in dot com firms. These firms have two objectives: to make an impact in the Internet and to obtain revenues from their activities. For this reason,...

This paper addresses an important issue in DEA: the selection of inputs and outputs to be included in a model. A two-stage methodology is suggested. The first stage applies a methodology based on comparing reduced models that do not include a particular input/output with extended models that...

DEA has been extensively used to measure the efficiency of financial institutions. Its advantages are clearly understood. But there are many unresolved problems. There are various views based on different modelling philosophies of what constitutes inputs and outputs in a financial institution....

A multi-activity DEA model for the joint determination of efficiencies with variable returns to scale is developed in this paper. The model contains an element of complexity that is not present in the previous DEA models for estimating returns to scale. It is found that apparent overall...

Microfinance Institutions (MFIs) are special financial institutions. They have both a social nature and a for-profit nature. Their performance has been traditionally measured by means of financial ratios. The paper uses a Data Envelopment Analysis (DEA) approach to efficiency to show that ratio...
