This paper provides robust evidence on feedback effects of violent conflicts on firm growth. It uses South Asian firm level data that contain rare employment information on countries that experience severe conflicts. We show that firm growth exists in conflict areas. Yet, there are fewer...

Despite a growing literature on the impacts of the COVID-19 pandemic, scant evidence currently exists on its impacts on air quality. We offer the first study that provides cross-national evidence on the causal impacts of COVID-19 on air pollution. We assemble a rich database consisting of daily,...

This paper explores the repercussions of the COVID-19 pandemic on the banking sector, focusing on the escalation of credit risk and its effects on non-performing loans (NPLs), loan loss provisions, and economic activity in the Republic of Kosovo. Amidst the global health crisis, the banking...

In the study, quantile regression (QR) is employed as the primary research tool, with ordinary least squares (OLS) regression used for comparison purposes. The motivation for this research stems from conflicting findings in existing literature regarding the spillover effects of Brent crude oil...

This paper is concerned with a set of parametric estimators that attempt to provide consistent estimates of average medical care costs under conditions of censoring. The main finding is that incorporation of the inverse of the probability of an individual not being censored in the estimating...

Experimental researchers routinely use regression in order to control for pre-treatment covariates. This practice has become controversial in the wake of recent demonstrations showing that this type of regression is prone to bias in small samples. Bias may even remain when units are sampled from...

This article outlines the limitations and fallacies of the routine use of standard linear regression.The method confines the analysis to the effect of the explanatory variable(s) on the mean of the dependent variable, and precludes the exploration of the various other ways in which the dependent...

It is an undisputed fact that weather risk increases over time due to climate change. However, qualification of this statement with regard to the type of weather risk and geographical location is needed. We investigate the application of novel statistical tools for assessing changes in weather...

In this paper, we introduce a methodology based on zero-inflated long-term survival data in order to deal with fraud rate estimation in bank loan portfolios. Our approach enables us to accommodate three different types of loan borrowers, i.e., fraudsters, those who are susceptible to default...

Let (X1, Y1), . . ., (Xn, Yn) be i.i.d. rvs and let l(x) be the unknown p-quantile regression curve of Y on X. A quantile-smoother ln(x) is a localised, nonlinear estimator of l(x). The strong uniform consistency rate is established under general conditions. In many applications it is necessary...
