This paper makes a contribution to the study of economic growth in developing countries by analysing the six largest Latin American Economies over 105 years within a two-equation framework. Confirming previous findings, physical and human capital prove to be key determinants of GDP per capita...

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...

Although research and development is widely considered to be an important source of growth, relatively little is known about how its effects differ across industries. This is mainly because much research on the effect of R&D has used either cross-section or time-series data and the remainder has...

The growth process for a technological leader is different from that of a follower. While followers can grow through imitation and capital deepening, a leader must undertake original research. This suggests that as the gap between the leader and the follower narrows, the follower must undertake...

After a dramatic slowdown of the 1970s, productivity growth in UK manufacturing in the 1980s returned to something like its pre-slowdown trend. This paper constructs a quarterly dynamic model of TFP growth in UK manufacturing using cointegration techniques, correcting for a variety of...

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...

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....

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...
