In recent decades, the labour share has experienced a downward trend in Portugal at the same time as a weaker and anaemic growth pattern. This seems to suggest that the fall in the labour share represents an important constraint on Portuguese economic growth, which is contrary to the orthodox claims around wage restraint policies – namely, that such policies are a necessary condition of improved macroeconomic performance, owing to their positive effects on private investment through higher profits and on net exports through reduced unit labour costs and a corresponding rise in competitiveness. This study assesses the relationship between labour share growth and economic growth by performing a time series econometric analysis focused on Portugal from 1971 to 2021. Findings show that labour share growth has positively impacted on economic growth in Portugal, which is in line with heterodox claims and particularly with post-Keynesian economics on the beneficial effects on private consumption played by the growth of wages. Findings also confirm that the Portuguese economy has followed a wage-led growth regime instead of a profit-led growth regime; that is, a rise in wages increases aggregate demand and, therefore, boosts economic growth because its beneficial effect on private consumption more than compensates for a prejudicial effect on private investment and on net exports. The study points out the urgent need to adopt public policies to support the growth of wages to avoid more decades of dismal growth and a new ‘secular stagnation’ in Portugal.

This year marks the 200th anniversary of the birth of Karl Marx, the last of the classical political economists. This article aims to mark the occasion by drawing attention to some of his key works in economics and to present some of his ideas in a way that will make sense to readers not familiar with or very much interested in the complexities of the labour theory of value. I begin with a brief biography and a summary of his main works in economics. I then explore in some detail ideas related to the economic surplus, unpaid labour and exploitation, and attempt to tease out the implications of his analysis for the determination of the wage share. While I argue that Marx has not succeeded in providing adequate theoretical support for his prediction that the wage share will fall as capital accumulates, he has nonetheless provided a very interesting and insightful collection of ideas by which we may, even today, approach a wide range of issues relating to production and distribution.

In this article, we study the minimum wage setting reform in Russia that aimed to decentralise the fixing of the minimum wage and to increase the involvement of social partners into this process. The old system of minimum wage setting was based on a single nationwide minimum wage which was differentiated across regions and occupations via a cumbersome framework of coefficients. The new system is a mixture of the government-set minimum wage at the federal level and collective agreements at the regional level. We show that the system of minimum wage setting has become more flexible. The reform succeeded in raising the real value of the minimum wage and increasing earnings of low-paid workers without causing significant negative effects in terms of employment. The reform did not lead to greater regional variation of minimum wages. Nevertheless, it introduced some new imbalances: an unintended consequence of the reform was the emergence of separate regional wage sub-minima for private and public sector workers in many regions. The major challenge in coming years is to strengthen the institutions of collective bargaining, introduce evidence-based evaluation and boost the capacities of government and non-government monitoring agencies.

A concern in the political economy is how national income is shared between labor and capital. This study evaluates long-term changes in factor income shares in three agri-food industries, their attribution to the level of factor usage or to factor compensation rates, and relation to changes in capital intensity and factor productivity. We find long-term stability in the profit and labor shares of farm income, decline in the profit share of agricultural services industry income, and increase in the profit share of food manufacturing income due to fewer productivity improvements being passed on to wage increases.
