This paper does an empirical comparison of time-invariant and time-varying technical inefficiency measures obtained from an econometric estimation of different panel data stochastic production frontier models. It estimates four panel data specifications of frontier models widely used in...

This paper explores the impact of refugees on the size of the underground economy in 28 European Union countries over the period from 1998 to 2017. It applies a nonlinear methodology by employing dynamic panel threshold estimations. The main findings uncover a nonlinear connection between...

In this paper, we investigate the effects of climate conditions on collected tax revenues, based on a panel-model approach. The dataset includes 123 countries and covers the period 1996-2010. The main results demonstrate that climate has a significant impact on tax revenues, the assumed function...

This paper is concerned with the estimation of employment relationship and employment efficiency under production risk using a panel of Zimbabwe¡¯s manufacturing industries. A flexible labour demand function is used consisting of two parts: the traditional labour demand function and labour...

This paper investigates the convergence behaviour of carbon dioxide emissions for 39 countries in the Americas from 1960-2016. A linear regression test of convergence which looks for conditional sigma convergence is employed, and a clustering algorithm is used to identify convergence clubs. The...

Background: Since the latter part of the 20th Century, countries have been particularly challenged by the trade-off that exists between delivering generous welfare provisions and strong economic growth. Such dynamics have stimulated a need to better understand the causes of income inequality so...

In this paper, we analyse the relationship between public primary deficit and debt for Italian sustainability over the 1862-2013 years. Our empirical strategy uses the wavelet analysis. The empirical evidence suggests the presence of a substantial fiscal sustainability in the long run for Italy....
