This is a summary of the paper entitled : “The Mean Squared Prediction Error Paradox”. In that paper, we show that traditional comparisons of Mean Squared Prediction Error (MSPE) between two competing forecasts may be highly controversial. This is so because when some specific conditions of...

We study the behavior and interaction of systematic and idiosyncratic components of risk in a cross-section of U.K. stocks. We find no clear evidence of a trend in any component of total risk, but we document different “regimes” in the behavior of each component of total risk, in their...

The allocation of funds to finance cohesion policies has been a significant European and national level activity. We focus on the 2007-2013 and 2014-2020 programming periods within a 23-year (2000 to 2022) time frame to assess whether and how cohesion funds have affected per-capita income growth...

The paper deals with the detection and measurement of the level of persistence on aggregate private consumption in Portugal, USA, European Union and EuroZone as well as on some categories of aggregate consumption in Portugal. By the use of a non-parametric methodology applied to monthly data...

This paper argues that studying the effect of financial development and shocks on aggregate growth volatility will not be informative because they affect growth volatility through its different components. Volatility declines either a consequence of a change in the nature of shocks or a change...

This paper was presented in June 1974 at the Symposium ―On the Measurement of Factor Productivities‖ at the castle Reisensburg in Bavaria, and was published in the book of proceedings from this Symposium. It contains results of several years of research about the economies of six East...

Econometrics is the area of statistics concerned in analyzing economic data, for both economic and business applications. This document, introduces the intermediate concepts of this area, for students already familiarized with basic econometric theory. In particular, topics concerning...

The divergence of the purchasing power parity from the equilibrium exchange rate is attributed to various factors. Productivity differentials between the countries are said to be one of the main sources, which lead to productivity bias hypothesis. The hypothesis suggests that a relatively more...

Generally, determining the size and magnitude of the omitted variable bias (OVB) in regression models is challenging when multiple included and omitted variables are present. Here, I describe a convenient OVB formula for treatment effect models with potentially many included and omitted...

Whilst the issue of whether or not per capita GDP adheres to the convergence theory continues to draw increasing attention within the academic paradigm, with very little consensus having been reached in the literature thus far. Our study contributes to the literature by examining the...
