This paper examines the problem of nonexistence of equilibrium in a simple search model with asymmetric information. A pure-strategy, symmetric Nash equilibrium fails to exist because adverse selection arising from steady-state considerations causes a nonconcavity in the payoff function.

We provide insights into determinants of the rating level of 371 issuers which defaulted in the years 1999 to 2003, and into the leader-follower relationship between Moody's and S&P. The evidence for the rating level suggests that Moody's assigns lower ratings than S&P for all observed periods...

This paper purports to provide some evidence on the effect of rating agencies on herding in financial markets. By means of a laboratory experiment, we investigate the effect and interaction between private and public information. Previous experiments showed that lemmings behaviour can survive in...

This dissertation was written by Christopher Weber during his time as a research assistant at the Center for Economic Studies (CES) at the Ludwig-Maximilians-Universität (LMU) Munich. It was handed in at the department of Economics at the LMU Munich in July 2016. The goal of the thesis is to...

Standard explanatory variables that determine credit ratings do not achieve significant effects in a sample of 100 US non-financial firms in an ordered probit panel estimation. Sample size and selection as well as the distribution of explanatory variables across rating classes may be the cause...

We report on the current state and important older findings of empirical studies on corporate credit ratings and their relationship to ratings of other entities. Specifically, we consider the results of three lines of research: The correlation of credit ratings and corporate default, the...

This paper investigates the link between sovereign ratings and macroeconomic fundamentals for a group of euro area countries which recorded rating downgrades amid the euro area sovereign debt crisis. We apply an elaborated econometric estimation technique, based on a Bayesian ordered probit...

In this paper, we propose a new method to assess the impact of sovereign ratings on sovereign bond yields. We estimate the impulse response of the interest rate, following a change in the rating. Since ratings are ordinal and moreover extremely persistent, it proves difficult to estimate those...

Green bonds are a new financial tool that has developed rapidly in the context of climate change risks. Their proceeds are used to finance only environmentally friendly projects. This paper aims to examine the determinant factors of the green bonds issue in the context of the European Union...

Relying on a perspective borrowed from monetary policy announcements and introducing an econometric twist in the traditional event study analysis, we doc- ument the existence of an "event risk transfer", namely a significant credit risk transmission from the sovereign to the corporate sector...
