What Causes Firm Profitability Variation in the EU Food Industry? A Redux of Classical Approaches of Variance Decomposition

Abstract: Since the 1980s economic researchers have applied variance decomposition methods such as ANOVA or components-of-variance (COV) in order to determine the importance of different effects for firm profitability variation. Nevertheless, these studies either focus on entire manufacturing sectors or on the U.S. food sector. This article, therefore, aims to determine the sources of firm profitability variation for EU food processors using the classical approaches of hierarchical ANOVA and COV. The paper also highligh… Show more

“…The assessment of competitiveness from a microeconomic point of view is usually based on traditional performance indicators (in the agri‐food sector, e.g., Bezat‐Jarzębowska & Rembisz, ; Madau, ). Firm‐specific factors are also considered as the key sources of firm performance in agribusiness sectors (e.g., Blažková & Dvouletý, ; Chaddad & Mondelli, ; Hirsch & Schiefer, ; Hirsch, Schiefer, Gschwandtner, & Hartmann, ). Therefore, we selected the indicators of performance based on the profit, value‐added and costs that can be considered as applicable outcome variables to assess the competitiveness of firms, that is, PCM , ROA , Value Added per Labour cost and Growth of Labour Costs .…”

“…COV is based on the assumption that the effect levels in the analyzed sample are randomly chosen from the population of levels (Searle et al, 2006;. In addition, ANOVA results are highly sensitive to the chosen pattern of effect introduction (Hirsch & Schiefer, 2016). Finally, both ANOVA and COV do not account for possible correlations between individual effects (Misangyi et al, 2006).…”

“…Blažková & Dvouletý, 2018b;Chaddad & Mondelli, 2013), the most variability of the firm performance is explained by the firm-level determinants (e.g. Goddard et al, 2009;Hirsch & Schiefer, 2016).…”
