This paper looks at some recent work on estimating quadratic variation using realised variance (RV) - that is sums of M squared returns. This econometrics has been motivated by the advent of the common availability of high frequency financial return data. When the underlying process is a...

In this paper we study the reliability of the mixed normal asymptotic distribution of realised variance error, which we have previously derived using the theory of realised power variation. Our experiments suggest that the asymptotics is reliable when we work with the logarithmic transform of...

This paper provides limit distribution results for power variation, that is sums of powers of absolute increments, for certain types of time-changed Brownian motion and $alpha $-stable processes. Special cases of these processes are stochastic volatility models used extensively in financial...

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...

This paper considers a model of endogenous growth with two sectors. It shows that it may be desirable to concentrate research in one sector, and so have unbalanced growth, but that the pressure of competition in research may cause the private sector to spread research too widely, and so have...

In order to assess the effect of jumps on realised variance calculations, we study some of the econometric properties of time-changed Levy processes. We show that in general we can derive the second order properties of realised variances and use these to estimate the parameters of such models....

This paper highlights a problem in using the first-differenced GMM panel data estimator to estimate cross-country growth regressions. When the time series are persistent, the first-differenced GMM estimator can be poorly behaved, since lagged levels of the series provide only weak instruments...

We use high frequency financial data to proxy, via the realised variance, each days financial variability. Based on a semiparametric stochastic volatility process, a limit theory shows you can represent the proxy as a true underlying variability plus some measurement noise with known...

This paper examines the long-run (steady-state) relationship between levels of educational human capital and levels of income for the 15 major states of India between 1965 and 1992. The relationship is estimated using the Pooled Mean Groups (PMG) technique; which produces common long-run...

Millennium development goal (MDG) of poverty reduction aims for halving of the head-count ratio over the period 1990-2015. Available studies draw attention to the gap between observed and required growth rates, the difficulties of sustaining the latter over time, and whether the policy stance of...
