We analyze a rating agency's incentives to distort ratings in a model with a monopolistic profit maximizing rating agency, a continuum of heterogeneous firms, and a competitive market of risk-neutral investors. Firms sell bonds, the value of a firm's bond is known to the firm and observable by...

We study a model in which an issuer can manipulate information obtained by a credit rating agency (CRA). Better CRA screening reduces the likelihood of a high rating, but increases the value of a rated security. We find that improving the prior quality of assets can have no effect on the quality...

In this study we consider the suitability of two methods of returns based style analysis for classification of investment styles for a single asset class, US Diversified Equity Funds. We extend Sharpe (1992) style Returns Based Style Analysis (RBSA) to form style groups using cluster analysis...

The present paper develops a simple asymmetrical informational model that allows us to understand the individual´s willingness to participate in a strike. We develop and compare two signaling models of strikes: in one, firms are able to monitor and enforce hours and offer different workweeks to...

The paper reviews models of the physician-patient relationship to derive testable hypotheses about the relation between health, demand for medical services and patient's compliance. The models imply that in addition to existing information asymmetries the actions that physician and patient...

Eine große Herausforderung der multivariablen Analyse mit bilanziellen Kennzahlen besteht in der Identifikation derjenigen Kennzahlen, die zur besten Modellperformance führen und dabei möglichst leicht interpretierbar und intuitiv bleiben. Die Menge der in Frage kommenden Kennzahlen ist in...

The study of firms' default has attracted wide interest among both practitioners and scholars. However, attention has often been limited to a relatively small set of financial variables. In this work, we try to increase the scope of analysis extending the investigation to other possible...

The corporate credit risk literature has many studies modelling the change in the credit risk of corporate bonds over time. There is far less analysis of the credit risk for portfolios of consumer loans. However behavioural scores, which are commonly calculated on a monthly basis by most...

Although there is a wide consensus that rating agencies have frequently failed to predict major crises, the literature on sovereign ratings has so far mostly focused on explaining the rating level rather than explaining the timing of the rating decision. In this paper we aim to fill this gap in...
