Abstract

This document is the Accepted Manuscript version of the following article: Chrysovalantis Amountzias, ???An Investigation of the Degree of Market Power in the Greek Manufacturing and Service Industries???, Journal of Industry, Competition and Trade, first published online 2 February 2017. Under embargo. Embargo end date: 2 February 2019. The final publication is available at Springer via http://dx.doi.org/10.1007/s10842-017-0245-4This paper investigates the degree of market power in the Greek manufacturing and service industries over the period 1970???2007. The markup model developed by Hall (1988) and Roeger (1995) is taken into consideration where market power is expressed as the difference between the selling price and the marginal cost of production. The analysis will be conducted in three steps; the first step estimates the price-cost margin of the manufacturing and services industries over 1970???2007; the second step applies the cross section specification under which the markup ratio is obtained for the 23 manufacturing and 26 service 2-digit ISIC sectors of the panel sample; and the third step estimates the price-cost margin of the manufacturing and services industries for each year over 1973???2007 by employing the Hall-Roeger time series specification. The empirical findings suggest that both industries exert a positive markup ratio; however, the service industry appears to be less competitive than the manufacturing industry

The Effects of Competition, Liquidity and Exports on Markups: Evidence from the UK Food and Beverages Sector

“…This shows that the growth rate of output of the sector over 2007-2016 exceeds the growth rate of inputs by 12%, thus reflecting a positive markup ratio consistent with imperfect competitive conduct 21 . Relatively, this value is lower compared to other food and beverages sectors (Bottasso and Sembenelli, 2001;Christopoulou and Vermeulen, 2012;Amountzias, 2017) but it is consistent with the findings of Warzynski (2003, 2006). The markup ratio of the UK food and beverages sector over 1989-1997 is 1.121 which is almost identical with the estimated value of this study.…”

Pricing Decisions and Competitive Conduct Across Manufacturing Sectors: Evidence from 19 European Union Manufacturing Industries

“…Some of these studies refer to Belgium(Dobbelaere, 2004), Greece(Polemis, 2014;Amountzias, 2017), Ireland(Boyle, 2004), Slovenia(De Loecker, 2007), Sweden(Wilhelmsson, 2006) and the UK Warzynski, 2003, 2006;Amountzias, 2018). 14 Nevertheless, De Loecker and Eeckhout (2017) support that higher markup ratios may not always reflect market power.…”
