Lessons From Single-Company Event Studies: The Importance Of Controlling For Company-Specific Events, Scott D. Hakala Aug 2010

Lessons From Single-Company Event Studies: The Importance Of Controlling For Company-Specific Events, Scott D. Hakala

Scott D Hakala

Single-company event studies are commonly employed in applied practice, such as in analyzing market efficiency, reliance, and damages in securities litigation. However, the presence of significant company-specific events among the observations used to estimate the market model results in significantly biased, overstated standard errors (a well-known omitted variables problem) and less reliable coefficient estimates in such studies. This is a frequently over-looked or neglected issue that renders the statistical inferences in single-company event studies employing using more traditional event study techniques biased and often unreliable. This paper demonstrates through simulation and actual examples that, even allowing for errors in implementation, …


Relational Contract Theory And Management Contracts: A Paradigm For The Application Of The Theory Of The Norms, Michael Diathesopoulos Jun 2010

Relational Contract Theory And Management Contracts: A Paradigm For The Application Of The Theory Of The Norms, Michael Diathesopoulos

Michael Diathesopoulos

This paper examines management contracts as a paradigm for the application of relational contracts theory and especially of the theory of contractual and relational norms. This theory, deriving from Macauley's implications, but structured and analysed by I.R. MacNeil gives us a framework for the explanation and understanding of contractual obligations and business relations' rules and practice. After presenting the key literature about the norms theory and especially defining the content of MacNeil's norms, we define management contracts as relations, characterised by a high relational element and we explain why, investigating all their features, which make them a suitable object for …


What Determines Professionals’ Bankruptcy Fees: An Empirical Investigation, Gijs Van Dijk, Martin Gramatikov Jan 2010

What Determines Professionals’ Bankruptcy Fees: An Empirical Investigation, Gijs Van Dijk, Martin Gramatikov

Martin Gramatikov

Countries have adopted different approaches to compensate bankruptcy trustees for winding up the estate. The approaches vary from state trustees to funding mechanisms where bankruptcy trustees receive a fixed fee, to a system where their fees depend on the size of the assets. Few studies have addressed the cost-effectiveness of the different approaches. This study contributes to this topic by examining the fees of the winding up, including an analysis of the determinants of these fees. After analyzing 289 Dutch bankruptcies consisting of short-term and medium-term cases, we find substantial differences in the mean hourly remuneration fees of bankruptcy trustees. …


Regulation By Markets And Higher Education, Benedict Sheehy Dec 2009

Regulation By Markets And Higher Education, Benedict Sheehy

Benedict Sheehy

Markets have a number of uses. One increasingly important use by politicians is as a means of regulating the supply and distribution of goods and services formerly supplied and distributed by governments on non-market bases. The use of markets as a regulator of higher education is not novel. However, the increased reliance on markets as a regulator of higher education is an on-going experiment with certain predictable failures. This article explores the uses of the market in the supply and distribution of higher education and weighs it against the stated policy objectives, with particular attention to the application proposed in …
