We investigate the relationship between long-term U.S. stock market risks and the macroeconomic environment using a two component GARCH-MIDAS model. Our results show that macroeconomic variables are important determinants of the secular component of stock market volatility. Among the various...

This paper presents a new volatility model with time-varying volatility persistence (TVP) that is governed by the dynamics of an explanatory variable. We extend the GJR-GARCH model by introducing a time-varying GARCH coefficient that is linked to the variable in a parsimonious way using MIDAS...

We consider the problem of testing for an omitted multiplicative long-term component in a simple GARCH model. Under the alternative there is a two-component model with a short-term GARCH component that fluctuates around a smoothly time-varying long-term component which is driven by the dynamics...

We consider the problem of testing for an omitted multiplicative long-term component in GARCH-type models. Under the alternative there is a two-component model with a short-term GARCH component that fluctuates around a smoothly time-varying long-term component which is driven by the dynamics of...

We scrutinize the impact of dividend policy on stock price volatility by considering the seminal paper of Baskin (1989). In this context, we examine the relationship between volatility and three dividend policy indicators, dividend yield, dividend payout, and stock repurchases, for 1,221 firms...

The neo-classical finance theory suggests that capital markets can reasonably reflect the value of listed companies, but it ignores the link between the real economy and the capital market. The current study conducts an analysis of the relevance of the stock return volatility to the company's...

In this paper, we compare the equity returns of dividend-paying and non-dividend paying firms. We find no unconditional return difference even though non-dividend paying firms have many characteristics that suggest high risk. Equivalently, because non-dividend paying firms have high...

Many electricity markets exhibit an oligopolistic structure with market participants whose individual trading activities may shift prices essentially. In this context, the question of how to optimally liquidate an existing electricity futures portfolio over a fixed time horizon under the...

This paper provides empirical evidence regarding the causal links between macroeconomic uncertainty and output growth using Greek data. Uncertainty is considered in distinct components, namely the inflation uncertainty and the output growth uncertainty. The results reveal significant negative...

The Great Recession endured by the main industrialized countries during the period 2008-2009, in the wake of the financial and banking crisis, has pointed out the major role of the financial sector on macroeconomic fluctuations. In this respect, many researchers have started to reconsider the...
