We develop a theoretical model to study the effects of an ad valorem taxation regime differentiated according to product characteristics (quality) within an imperfectly competitive market. Then to test our theoretical prediction we use yearly data from the Irish automobile market during the...

This paper contributes to the empirical literature on the distributional impact of competition. Using a novel combination of the national survey of household expenditure and the business structure database for the UK, it establishes two descriptive facts. First, the poor are relatively more...

In their paper, Sampson (2023) introduces a theoretical framework and conducts empirical testing to elucidate the impact of gaps in countries' innovative efficiencies on income, wages, and trade dynamics. We successfully replicate the paper's findings by running the provided codes, and confirm...

Sutton (1998) offers us a simple way to model firm size distributions across differentiated products industries. We analyse the implications of this approach for company markups using a structural model for a specific industry. We incorporate the complexities of multi-product (brand) companies...

This paper provides an empirical analysis of own- and cross-price elasticities of substitution for the 1989-2000 Italian automobile industry. We use product-level data consistent with a structural model of equilibrium in a differentiated products oligopolistic industry and follow a random...
