Inflation and unemployment rate were largely disconnected between 2000 and 2019 in advanced economies. We decompose core inflation into two parts based on the cyclical sensitivity of CPI components and document several salient facts: (i) both the cyclical and non-cyclical parts had surges across...

In this paper I demonstrate, both theoretically and empirically, that the interpretation of regression estimates of between-group differences in economic outcomes depends on the relative sizes of subpopulations under study. When the disadvantaged group is small, regression estimates are similar...

We compare real wage differences between centralized and peripheral areas and highly centralized and peripheral areas using vast information of German administrative data that contains more than 2.8 Million individuals and 660,000 firms. We provide substantial empirical evidence that most of the...

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...
