This study, using the Cox proportional hazards model, finds that the risk of takeover rises with cost inefficiency. It also finds that a firm faces a significantly higher risk of takeover if its cost performance lags behind its industry benchmark. Moreover, these findings appear to be remarkably...

This book originated from a 2010 conference marking the fortieth anniversary of the publication of the landmark "Phelps volume," Microeconomic Foundations of Employment and Inflation Theory, a book that is often credited with pioneering the currently dominant approach to macroeconomic analysis....

We give a counterexample to the Strong Bang-Bang Conjecture according to which any 3 - 3 embeddable matrix can be expressed as a product of six Poisson matrices. We exhibit a 3 - 3 embeddable matrix which can be expressed as a product of seven but not six Poisson matrices. We show that an...

This paper is concerned with asymptotic properties of the maximum likelihood estimators for the discrete-time square-root process. This process and its generalizations are employed in financial literature as models for movements of asset prices. the considered process is nonergodic and therefore...

Despite mounting evidence to the contrary, credit migration matrices, used in many credit risk and pricing applications, are typically assumed to be generated by a simple Markov process. Based on empirical evidence, we propose a parsimonious model that is a mixture of (two) Markov chains, where...

We explore how general economic conditions impact defaults and major credit rating changes by fitting reduced-form Cox intensity models with a broad range of macroeconomic and firm-specific ratings-related variables. For all corporate issuers in the period 1981–2002 we find both types of...

Since financial myths exploded in the 1980s, the perspective of time creates a unique opportunity to update and expand the analysis begun in Glenn Yago's 1991 book,Junk Bonds: How High Yield Securities Restructured Corporate America (Oxford University Press). At the time of its publication, Junk...
