Concentration in Product Markets
SSRN Electronic Journal, 2021 This paper uses new data to reexamine trends in concentration in U.S. markets from 1994 to 2019. The paper's main contribution is to construct concentration measures that reflect narrowly defined consumption-based product markets, as would be defined in an antitrust setting, while accounting for cross-brand ownership, and to do so over a broad range of

U.S. Market Concentration and Import Competition [PDF]
Review of Economic Studies, 2021 Abstract Many studies have documented that the sales concentration of U.S. producers has risen in recent decades. In this article, we show that this increase was accompanied by more entry and growth of foreign competitors. Using confidential census data covering the universe of all firm sales in the U.S.

Market Failure and Land Concentration [PDF]
SSRN Electronic Journal, 2009 Utilizing a 2002 household-level World Bank Survey for rural Turkey, this paper explores the link between concentration of land ownership and rural factor markets. We construct a unique index that measures market malfunctioning based on the neoclassical model linking land and labor endowments through factor markets to household income.

The PI3Kδ inhibitor roginolisib (IOA‐244) preserves T‐cell function and activity
Molecular Oncology, EarlyView.Identification of novel PI3K inhibitors with limited immune‐related adverse effects is highly sought after. We found that roginolisib and idelalisib inhibit chronic lymphocytic leukemia (CLL) cells and Treg suppressive functions to similar extents, but roginolisib affects cytotoxic T‐cell function and promotion of pro‐inflammatory T helper subsets to a
