I introduce the concept of hybrid intermediaries: financial conglomerates that control a multiplicity of entity types active in the “assembly line” process of modern financial intermediation, a system that has become known as shadow banking. The complex bank holding companies of today are the best example of hybrid intermediaries, but I argue that financial firms from the “nonbank” space can ju...

We investigate several statistical properties of the order book of three liquid stocks of the Paris Bourse. The results are to a large degree independent of the stock studied. The most interesting features concern (i) the statistics of incoming limit order prices, which follows a power-law around the current price with a diverging mean; and (ii) the humped shape of the average order book, which...

This study evaluated the productivity of non-profit hospitals in the USA in applying DEA-base Malmquist productivity Change index, decomposed into technical efficiency change index and technical progressive change index. Data used for this analysis consisted of 118 non-profit hospital utilization data and financial statements from 1993 through 2003. DEA-based Malmquist was conducted to measure ...

For over a decade, empirical studies examining organizational performance of IT investment have been far from conclusive. An issue that has led to the ongoing debate is inadequate methodology applied in measuring IT values. The traditional measures have been focused on financial ones such as return on investment and return on sales. Researchers therefore suggested the need to use more non-finan...

This article explains how data envelopment analysis can be used as a decision support system to perform financial statement analysis and demonstrates the benefits DEA offers over traditional financial statement analysis techniques. A major advantage of the DEA approach is that it clearly identifies the factors contributing to the performance of company over its competitors.

In this paper, we will propose numerically tractable formulations of the diversification-consistent DEA tests, which generalize traditional DEA tests as well as mean-risk models. We employ general deviation measures to measure risk of the investment opportunities. We will compare strength of the tests and give characterizations of efficient and inefficient investment opportunities. US industry ...

Traditional banking is built on four pillars: SME lending, access to public liquidity, deposit insurance, and prudential supervision. This vision has been shattered by repeated bailouts of shadow financial institutions. This paper puts “special depositors and borrowers” at the core of the analysis, provides a rationale for the covariation yielding the quadrilogy, and analyzes how prudential reg...
