We document the evolution of intergenerational income (IGI ) inequality, measured as the relative income between old and young individuals, using harmonised microdata from 42 countries at different stages of economic development. In the last 20 years, IGI inequality has increased (in favour of...

In this paper, we study the hierarchical hub network design problem with a ring-star-star structure. In this problem, the hubs are located in two layers. In the first layer, central hubs (main hubs) are located in a ring structure, and in the second layer, secondary hubs are located. Each...

This paper investigates the importance of firm dynamics, including entry and exit and the allocation of carbon emissions across firms, on the green transition. Using the 2000-2019 firm-level register data on greenhouse gas emissions matched with the Financial Statement data in the Finnish...

We reformulate and decompose the Pearson and Spearman correlation coefficients into two components. We recommend the first component for detecting linear or monotonic relationships and the second for recognizing patterns of two parallel lines, providing robust versions to outliers. Thus, we...

We employ a time-varying risk price model that allows us to track the change in risk prices. We find that the output gap generates the time-varying market and momentum risk prices, but the exposures to the output gap have the opposite signs. In contrast, we do not observe that the output gap is...

Analyzing a large sample of gross fund-level and deal-level returns in Private Equity (PE), we study systematic differences in investment skills across PE firms and what investors can learn about the true skill of PE firms from past performance. We extend the framework of Korteweg and Sorensen...

Network theory suggests that supply shocks propagate downstream whereas demand shocks propagate upstream. I propose a method to decompose return innovations to supply and demand effects based on this observation. Specifically, If a focal firm return innovation affects its supplier's sales growth...
