This paper proposes a procedure for testing alternative specifications of the short term interest rate's dynamics which takes into account that according to some restrictions the interest rate is nonstationary, i.e. the traditional test statistic has a non-standard distribution. Moreover, we do...

The paper elaborates on the employment intensity of growth. Previous evidence regarding this question is surveyed. Empirical results concerning Europe and selected other industrial countries reveal that the cyclical link between unemployment and growth is still stable in the nineties. However,...

I examine the relative information roles among West Texas Intermediate spot crude price and four futures contracts (F1 through F4) with different maturities. Using a cointegrated system with a non-unitary cointegrating vector, I address price discovery by investigating which price is more...

This study examines the determinants of bond yield spreads for 22 emerging markets in the period 1998-2009. Several determinants are considered. In addition, I consider the connection between volatility and bond yield spreads. Volatility and central bank transparency are two factors common to...

The purpose of the regulated halts on stock exchange markets is to spread the information on the market and to protect the interests of the small shareholders. The aim of this work is to empirically investigate the price limits on the French stock exchange market. We analyze the impact of such...

We discuss efficiency of the quadratic bridge volatility estimator in comparison with Parkinson, Garman-Klass and Roger-Satchell estimators. It is shown in particular that point and interval estimations of volatility, resting on bridge estimator, are considerably more efficient than analogous...

I perform a regression analysis to test two of the most famous heuristic rules existing in the literature about the behavior of the implied volatility surface. These rules are the sticky delta rule and the sticky strike rule. I present a new specification to test the sticky strike rule, which...

In this note we describe and compare two methodologies for calculating implied volatility of commodity prices, given the market prices of options on futures or implied volatilities, and a forward curve. The first methodology is fitting an exponential mean-reversion jump-diffusion model to the...

A simple, empirical-based approach to decompose Realized Variance (RV) is proposed, with supportive theoretical argument and empirical evidence. Under the proposed framework, RV is interpreted as a product of the intensity and variance of relevant price changes. Holding the variance aspect...
