  1. Data and Market Power
    Author: Eeckhout, Jan; Veldkamp, Laura
    Published: May 2022
    Publisher:  National Bureau of Economic Research, Cambridge, Mass

    Might firms' use of data create market power? To explore this hypothesis, we craft a model in which economies of scale in data induce a data-rich firm to invest in producing at a lower marginal cost and larger scale. However, the model uncovers much... more

    Might firms' use of data create market power? To explore this hypothesis, we craft a model in which economies of scale in data induce a data-rich firm to invest in producing at a lower marginal cost and larger scale. However, the model uncovers much richer interactions between data, welfare and market power. Data affects risk, firm size and the composition of the goods firms produce, all of which affect markups. The tradeoff between these forces depends on the level of aggregation at which markups are measured. Empirical researchers who measure markups at the product level, firm level or industry level come to different conclusions about trends and cyclical fluctuations in markups. Our results reconcile and re-interpret these facts. The divergence between product, firm and industry markups can be a sign that firms are using data to reallocate production to the goods consumers want most

    This paper overviews theoretical and empirical contributions that study political borders from an economic perspective. It reviews theories of the number and size of nations focused on the trade-off between economies of scale in public-good provision and heterogeneity of preferences over public policies as well as on the factors affecting this trade-off, such as democratization, international openness, and conflict. It also reviews studies of political integration and disintegration that focus on economic inequality, redistribution policies, and the geographical distribution of resources. Finally, the paper discusses recent empirical studies that shed light on the relations among heterogeneity, conflict, and borders. This line of research is part of a growing literature on the interplay between cultural variables and economic and political outcomes.
