This paper derives the linear interpolation bias of realized volatility. To avoid the bias, the Fourier series estimator has been proposed by Malliavin and Mancino (2002). We examine the theoretical relationship between the Fourier estimator and realized volatility and show that the latter is...

In this paper we present explanation on the phenomenon pointed out in Cook and Manning (2002) on the unusual behaviour of the Dickey-Fuller test in the presence of trend misspecification. It appears that the rejection frequency of the unit root tests in the presence of trend misspecification is...

In this paper we study the characteristics of the non stationarity of the covariance structure of the S\&P 500 returns by analyzing the time spectral density of the data. We show that the S\&P 500 returns has the same characteristics as the modulate white noise process. So, some precautions must...

This paper introduces the fractionally integrated Bi-parameter smooth transition autoregressive model (FI-BSTAR model) as an extension of BSTAR model proposed by Siliverstovs (2005) and the fractionally integrated STAR model (FI-STAR model) proposed by van Dijk et al. (2002). Our FI-BSTAR model...

This paper addresses the combination of incomplete prior and sample information. In difference to the mixed estimation approach developed by H. Theil and A.S. Goldberger, dealing with prior knowledge of regression coefficients, we consider prior information on future observations of the...

This paper explores the link between industry concentration, which is a feature of the product markets in which firms operate, and the risk of a firm's cash flows, offering the first empirical evidence of the risky cash-flow implications of industry market structure. Our analysis shows that on...

Theoretical constraints on economic model parameters often are in the form of inequality restrictions. For example, many theoretical results are in the form of monotonicity or nonnegativity restrictions. Inequality constraints can truncate sampling distributions of parameter estimators, so that...

We propose a new variant of RESET that is appropriate for distributed lag models. Monte Carlo evidence on size and power strongly supports the use of the new variant instead of the traditional RESET.
