This classical trade-off depends on the financial contracting between the entrepreneur...

The COVID-19 pandemic has affected most companies' profits negatively, but other companies did exceptionally well, recording excess profits during the pandemic. In this paper we estimate the scale of these excess profits, their determinants, and the revenue potential of excess profits tax. To...

This paper studies nonparametric identification and counterfactual bounds for heterogeneous firms that can be ranked in terms of productivity. Our approach works when quantities and prices are latent, rendering standard approaches inapplicable. Instead, we require observation of profits or other...

This paper quantifies global demand, supply, and uncertainty shocks and compares two major global recessions: the 2008-09 Great Recession and the COVID-19 pandemic. Two alternative approaches are used to decompose economic shocks: text mining techniques on earning call transcripts and a...

Can cost-reducing, technical change lead to a fall in the long run rate of profit if class struggle manages to keep the rate of exploitation constant? In this paper we demonstrate, in a general circulating capital model, that if (a) the technical change is capital-using labor-saving (CU-LS), (b)...

We exploit a recent Swedish tax reform, implying higher marginal tax rates for the top 5% of the earnings distribution, to learn about earnings responses in an economy where taxes already are high. Using a simple and graphical cross sectional method, we estimate earnings elasticities in the...

We contribute to the study of the conceptualization and measurement of the rate of profit of the financial and nonfinancial sectors. We assemble a new data set for the US economy to construct measures of the profit rate for each sector: the return on equity, the return on assets, and the...
