This paper analyses the role of investor sentiment in the contemporaneous dynamics of spot and futures markets and in volatility spillovers between them. To explore this issue, we analyse spot and futures markets on stock market indexes in different countries: the S&P500 for the US, and a...

This study presents a first comparative analysis of Lasso-type (Lasso, adaptive Lasso, elastic net) and heuristic subset selection methods. Although the Lasso has shown success in many situations, it has some limitations. In particular, inconsistent results are obtained for pairwise highly...

Several nonlinear time series models have been proposed in the literature to explain various empirical nonlinear features of many observed financial and economic time series. One model that has gained much attention is the so-called self-exciting threshold autoregressive (SETAR) model. It has...

The behavior and stability of over-the-counter markets is of central concern to regulators. Little is known, however, about how the structure of these markets determine their properties. In this paper we consider an over-the-counter market populated by boundedly rational heterogeneous traders in...

We develop a quantitative model for structured microfinance instruments, which are regarded as an important means for refinancing microfinance institutions. The quantitative credit risk model presented takes into account the peculiarities of microfinance institutions and can be used for pricing...

In this article, we examine the relationship between implied and realised volatility in the Greek derivative market. We examine the differences between realised volatility and implied volatility of call and put options for at-the-money index options with a two-month expiration period. The...

The Australian federal election cycle, which occurs approximately every 3 years, causes much media attention and invokes indecision regarding investment decisions in both the real economy and financial markets. This paper constructs measures of political uncertainty and formally explores their...

The hedge and safe haven properties of gold in advanced economies’ financial markets are well documented in the literature. Studies of how this issue relates to emerging markets and developing countries are, however, very limited. This paper aims to fill this gap by empirically analyzing the...

This paper proposes an empirical study of the shape of recoveries in financial markets from a bounce-back augmented Markov Switching model. This model is estimated for monthly stock market returns data of five developed countries for the post-1970 period. The presence and shape of the...

The class of mixed normal conditional heteroskedastic (MixN-GARCH) models, which couples a mixed normal distributional structure with GARCH-type dynamics, has been shown to offer a plausible decomposition of the contributions to volatility, as well as excellent out-of-sample forecasting...
