The impact of firm-level Covid rescue policies on productivity growth and reallocation KU Leuven
We evaluate the impact of Covid-19 rescue policies on both firm-level and aggregate productivity growth, exit, and creative destruction. Using administrative data on the universe of firms’ support mechanisms in Flanders over 2019–2021, we first estimate the causal impact of this support program on firm-level outcomes. Firms that received support saw a 4%–5% increase in productivity, compared to similar firms that applied for, but did not obtain ...
The granular nature of emerging market economies: The case of Kazakhstan KU Leuven
This paper analyzes the granularity hypothesis in a large emerging economy, Kazakhstan. We use a new longitudinal dataset at the firm level and at quarterly frequency between 2012 and 2018 to document the size distribution of firms and to provide evidence that it follows a power law. We find that the largest 30 firms explain nearly 80 percent of the growth in aggregate total factor productivity. This confirms earlier research for the U.S. and ...
Does Automatic Wage Indexation Destroy Jobs? A Machine Learning Approach. KU Leuven
This paper analyzes the impact of automatic wage indexation on employment. To boost competitiveness and increase employment, Belgium suspended its automatic wage indexation system in 2015. This resulted in a 2% fall in real wages for all workers. In the absence of a suitable control group, we use machine learning for the counterfactual analysis. We artificially construct the control group for a difference-in-difference analysis based on the ...
Dominant Currencies: How Firms Choose Currency Invoicing and Why it Matters KU Leuven
We analyze how firms choose the currency of invoicing and the implications of this choice for exchange rate pass-through into export prices and quantities. Using a new dataset for Belgian firms, we find currency invoicing to be an active firm-level decision, shaped by the firm’s size, exposure to imported inputs, and the currency choices of its competitors. Our results show that the firm’s currency choice, in turn, has a direct causal impact on ...
