  Markups, Profit Shares, and Cost-Push-Profit-Led Inflation

  Michalis Nikiforos, Simon Grothe and Jan David Weber
  Abstract

  The post-pandemic surge in inflation was accompanied by a surge in the corporate share of profits. As a result, several economists and policy makers have given to it names such as “profit-led inflation” or “sellers’ inflation.” The present paper discusses the extent to which profit-led inflation, as an explanation for the recent surge in inflation, is compatible with what we know about the price-setting behavior of firms, income distribution, and inflation. We do that in juxtaposition to two recent critiques: that the increase in the profit share is the result of cyclical factors, and that the increase in import prices leads to higher profit shares even under constant markups. We show that there is little evidence that the recent surge in profitability is cyclical in nature. Moreover, after outlining the Structuralist/Kaleckian theories of prices and inflation we argue that profit-led inflation does not require an increase in the markup of the firms and is consistent with these theories. In the face of large import and other price shocks even under constant markups, firms are able to pass the burden of adjustment to real wages. Thus, the term profit-led emphasizes the distributional source and consequences of inflation. We also provide an empirical examination of the markups in the post-pandemic period using data from the Compustat database. We show that, on average, firms were able to increase or maintain their markups, although there is significant heterogeneity across sectors or the position of the firms in the distribution of markups.

  Contractionary Effects of Foreign Price Shocks (and Potentially Expansionary Effects of Inflation)

  Michalis Nikiforos and Simon Grothe
  Abstract

  Using the model proposed in Krugman and Taylor’s “Contractionary effects of devaluation” (1978), we examine the macroeconomic effects of shocks to foreign prices. We show that these shocks can be contractionary for two reasons: (i) because they imply a loss of income if an economy has a trade deficit or import prices increase proportionally more than export prices; (ii) because there is a redistribution of income from wages to profits and rent, which leads to a decrease in consumption and output (as the wage earner's propensity to consume is higher than those of profit earners and rentiers). An endogenous reaction of nominal wages to the increase in the price level might lead to even higher increases in prices, but mitigates the negative macroeconomic effects of the foreign price shocks because it reduces their negative distributional effects. If the proportional increase in nominal wages is higher than that of domestic prices, the distributional effect becomes positive. The opposite is the case with markups. If they increase in reaction to higher prices, they contribute to further price increases but they also exacerbate the negative distributional effects. The paper also provides an analytical solution for a general case of the model of Krugman and Taylor.

  Structural Change and Gender Sectoral Segregation in Sub-Saharan Africa

  Izaskun Zuazu
  Abstract

  Structural change has long been at the core of economic development debates. However, the gender implications of structural change are still largely unexplored. This paper helps to fill this gap by analyzing the role of structural change in the gender distribution of sectoral employment in sub-Saharan African countries. I employ aggregate and disaggregate measures of gender sectoral segregation in employment on a panel database consisting of 10 sectors and 11 countries during 1960–2010. Fixed effects and instrumental variables’ regression models show a significant, non-linear link between labor productivity and gender segregation. Increasing labor productivity depresses gender segregation at initial phases of structural change. However, further productivity gains beyond a certain threshold of sectoral development increases gender segregation. Country-industry panel data models complement the analysis by considering relative labor productivity as a determinant of sectoral feminization. The estimates suggest that manufacturing, utilities, construction, business, and government services are key to correcting gender biases in employment along the process of structural change.
