Purpose
This paper aims to explain the empirical relationship between competitiveness and economic growth in a globalizing world. In recent times, the advanced economies have experienced a slowdown of growth, whereas the BRICS countries continue to experience high growth. The authors explore the following question: Does competitiveness of nations’ degree of competition explains this differential in growth? The authors explore competiveness and growth in a macroeconomic perspective for the large economies in the OECD and BRICS countries.

Design/methodology/approach
The authors use dynamic panel data modelling technique to find the relationship between competitiveness and economic growth. This technique enables to control heterogeneity problem of this group to some extent. The focus variable of this study is annual GDP growth rate for the period 2007-2017. The proxies for measuring competitiveness in this paper are trade as percentage of GDP, product market regulation, unit labour cost and global competitive index. Innovation prevalence of foreign ownership, efficiency, competition, state of cluster development, venture capital availability, extent of market, research and development expenditure as percentage of the GDP mergers and acquisitions and multifactor productivity are the control variables.

Findings
The authors find that the degree of competitiveness competition is less likely to impact economic growth in the OECD countries because they have more or less similar competitive environment. Innovation, extent of market and state of cluster development and venture capital availability explaining growth differential. Increased competition is likely to affect growth negatively. This explains the oligopolistic structures of the world economy. However, the BRICS countries vary significantly in competitive environment. This is the reason of volatility in their growth. The conclusion is that competitiveness is important for sustained growth. Competitiveness is, however, an outcome of a set of policies, not a policy itself.

Research limitations/implications
Productivity data for OECD and BRICS countries are not available. Various series are not comparable. OECD countries have discontinued yearly unit labour cost series, and high frequency series are available but no such series for BRICS exists.

Practical implications
First, this paper proposes that wage growth, measured by the unit labour cost growth rate, is an important determinant of competitiveness amongst the nations. Wage growth is falling short of productivity growth in the OECD countries. This has implications for the long run sustainability of growth, skill development and inequalities in the region. Since 2011, world economic recovery is slow. Wage growth is imperative for generating sufficient private demand in the OECD countries. Second, this paper provides evidence that competitiveness is important for explaining growth in the OECD and the BRICS countries. However, it also highlights that competitiveness can be measured effectively by the trade differential or with the help of unit labour cost. Unaligned real effective exchange rate in terms of unit labour costs is the real cause of the problem.

Originality/value
Research in this area is still in infancy. This research finds that how competitiveness affects growth. A more competitive nation can sell more, but not necessarily grow rapidly. In development process, growth comes first, and at the latter stages, countries have to introduce effective reforms for competitiveness. This is the effect of competitiveness on growth by comparing various indexes.
