The story of John Snow's 1855 treatise "On the mode of communication of cholera" is a rollicking good tale – full of heroism, death, and statistics. But more fundamentally Snow's work is a sustained effort to convince skeptics, through argument and a wide variety of evidence, of the waterborne...

The study area is focused on the Philippine Trench, a hadal trench located in the axe of the collision of the Philippine Sea Plate and Sunda Plate, west Pacific Ocean. The research is aimed at the analysis of the trench geomorphology by a correlation between changes in slope steepness and...

The paper did not originally have an abstract. It explores the robustness of hedonic pricing estimation, focusing on four areas: 1) variable selection and treatment, 2) measurement error, 3) functional form, and 4) error distribution. The paper offers insights to guide the future conduct of...

We attempt to unveil the fine structure of volatility feedback effects in the context of general quadratic autoregressive (QARCH) models, which assume that today's volatility can be expressed as a general quadratic form of the past daily returns. The standard ARCH or GARCH framework is recovered...

This study introduces a new measure of ex ante litigation risk using scrutiny of SEC filings by the source of securities litigation—plaintiffs' lawyers—to reduce measurement error, relative to existing measures. We show that plaintiff-lawyer views proxy for the largely unobservable factors...

We develop a method of testing linearity using power transforms of regressors, allowing for stationary processes and time trends. The linear model is a simplifying hypothesis that derives from the power transform model in three different ways, each producing its own identification problem. We...

This paper builds on a previous paper that evaluates a spatial hedonic difference-in-differences model to estimate the effects on home prices of a public housing project in North Dallas. Here, we perform a spatial falsification exercise by simulating the spatial GMM estimation on over 5,000...

This study looks at the effects of participating in active labour market policy programs for persons with work disabilities. More in detail, it draws attention to the importance of taking into account the timing of when a work disability has been registered for persons attending ALMP programs....

A key point to assess the application of statistical learning models in Artificial Intelligence (AI) is the evaluation of their predictive accuracy. This because the "automatic" choice of an action crucially depends on the made prediction. While the best model in terms of fit to the observed...

Due to the current lockdown and restrictions related to the COVID-19 pandemic, U.S. commercial and domestic banks are facing cashflow and financial difficulties. This has led to many vulnerable customers losing their source of income. In this paper, we test whether U.S. commercial and domestic...
