This thesis discusses Zeno runs and their detection in timed automata networks. Specifically, we explore Zeno runs in the context of model checking with the tool UPPAAL. Zeno runs are transition sequences in the system that can execute arbitrarily fast, which conflicts with the real world experience where execution always takes time. Accordingly, most of the time the presence of Zeno runs in a ...

We use MD&A disclosures to predict current-year firm-level accruals using support-vector regressions. We call these predictions MD&A accruals. Our aim is to measure the explanatory power of MD&A disclosures for liquidity and critical accounting choices. We find that MD&A accruals explain a statistically and economically significant portion of firm-level accruals and identify more persistent acc...

We provide an econometric analysis for the factor models when the latent factors can be explained partially by several observed explanatory proxies. In financial factor models for instance, the unknown factors can be reasonably well predicted by a few observable proxies, such as the Fama-French factors. In diffusion index forecasts, identified factors are strongly related to several directly me...
