Countries have employed a variety of non-pharmaceutical interventions (NPIs) in order to curtail the Covid-19 pandemic. However, the success of individual measures in reducing the number of infections remains controversial. This paper exploits a panel data set of 182 countries to estimate the...

Individuals urbanize when the net benefits to urbanization exceed rural living conditions. Body mass, height, and weight are welfare measures that reflect the net difference between calories consumed and calories required for work and to withstand the physical environment. Nineteenth and early...

We propose a demand estimation method that allows researchers to estimate substitution patterns from unstructured image and text data. We first employ a series of machine learning models to measure product similarity from products' images and textual descriptions. We then estimate a nested logit...

This paper evaluates how different lengths of entry regulation impact market structure and market performance using a dynamic structural model. We formulate an oligopoly model in the tradition of Ericson and Pakes (1995) and allow entry costs to vary over time. Firms have the opportunity to...

When traditional measures for material conditions are scarce or unreliable, body mass, height, and weight are complements to standard income and wealth measures. A persistent question in welfare studies is the 19th century's 2nd and 3rd quarter's stature diminution, a pattern known as the...

The alleged liberal bias and high costs of fact-checker ratings (Nieminen & Rapeli, 2019) have prevented their ability to limit the spread of fake news. Wisdom-of-the-crowd-based approaches, recognized as a credible alternative to traditional fact-checking methods, have gained prominence for...

ARCH modelling framework of Engle (1982) and its GARCH generalization of Bollerslev (1986) gave a huge impetus to econometric model building in the field of financial time series with time-varying variance. The main idea of the models was to describe the most typical features of capital markets...

With the increasing importance of the service-providing sectors, information from these sectors has become essential to the understanding of contemporary business cycles. This paper explores the usefulness of the transportation services output index (TSI) as an additional coincident indicator in...

This paper considers the statistical analysis of large panel data sets where even after condi-tioning on common observed effects the cross section units might remain dependently distrib-uted. This could arise when the cross section units are subject to unobserved common effects and/or if there...

This paper introduces a novel approach for dealing with the 'curse of dimensionality' in the case of large linear dynamic systems. Restrictions on the coefficients of an unrestricted VAR are proposed that are binding only in a limit as the number of endogenous variables tends to infinity. It is...
