We propose a computationally efficient method to construct nonparametric, heteroskedastic prediction bands for uncertainty quantification, with or without any user-specified predictive model. The data-adaptive prediction band is universally applicable with minimal distributional assumptions,...

Universal approximation functions are well known and studied in canonical mathematics. Here we theorize the existence of an independent class of universal approximation agents and agent-based models. We draw upon historical references from mathematical analysis, the development of machine...

This paper is an expression of gratitude, remembrance and honour the jubilee of Prof. Tomasz Żylicz. As I have been invited to write a paper for a special issue of the CEEJ journal, I sincerely wanted to express regarding my friendship and my research that have been binding me with Tomasz in my...

The Advanced Placement (AP) economics education program serves thousands of high school students each year, many of whom receive college credit upon successful completion of an AP economics exam. The AP curriculum, and tests, are not explicitly tied to a set of economic learning objectives. In...

Purpose: To assess the predictive validity of Lott and Varney's (2022) ordinary least squares (OLS) multiple regression (MRA) causal model of the effect of immigrant population numbers, as a proportion of the total population, on the homicide victim rate for 31 European countries.Methods: The...

This is a course material (slides in pdf format) from the book 'Investment Decision Making For Firm and Project Valuation.' The book is originally in Spanish and is untitled as 'Decisiones de inversion. Para la valoracion financiera de proyectos y empresas.' Chapter 5 deals with how to prepare...

This review paper articulates the relationship between prediction market data and event studies, with a special focus on applications in political economy. Event studies have been used to address a variety of political economy questions - from the economic effects of party control of government...
