How much does public capital matter for economic growth? How large should it be? This paper attempts to answer these questions, taking the case of SSA countries. It develops and estimates a model that posits a nonlinear relationship between public investment and growth, to determine the...

High frequency financial data allows us to learn more about volatility, volatility of volatility and jumps.  One of the … estimates time-varying volatility robustly to jumps.  We improve the scope and efficiency of multipower variation by the use of … first nonparametric high frequency estimator of the volatility of volatility.  A fundamental device in the paper is a new …

This paper shows that realised power variation and its extension we introduce here called realised bipower variation is somewhat robust to rare jumps. We show realised bipower variation estimates integrated variance in SV models --- thus providing a model free and consistent alternative to...

GARCH models are commonly used as latent processes in econometrics, financial economics and macroeconomics. Yet no exact likelihood analysis of these models has been provided so far. In this paper we outline the issues and suggest a Markov chain Monte Carlo algorithm which allows the calculation...
