This paper revisits the least squares estimator of the linear regression with a structural break. We view the model as an approximation to the true data generating process whose exact nature is unknown but perhaps changing over time either continuously or with some jumps. This view is widely...

We investigate a model in which we connect slowly time varying unconditional long-run volatility with short-run conditional volatility whose representation is given as a semi-strong GARCH (1,1) process with heavy tailed errors. We focus on robust estimation of both long-run and short-run...

While a great number of predictive variables for stock returns have been suggested, their prediction power is unstable. We propose a Least Absolute Shrinkage and Selection Operator (LASSO) estimator of a predictive regression in which stock returns are conditioned on a large set of lagged...

A substantial body of research suggests that it is difficult to account for all of the asset price volatility in terms of news. This paper attempts to explain the excess volatility puzzle as a consequence of competitive interaction between market participants. We develop a model of competitive...

The retirement systems in many developed countries have been increasingly moving from Defined Benefit (DB) towards the Defined Contribution (DC) system. In such systems, financial and longevity risks are shifted from the pension provider to the retiree. This paper uses a probabilistic approach...
