The Hoberg and Phillips Text Based Industry Classifications have a spatial representation. All firms have a location in a product market space shaped as a unit sphere. Competitive product markets are areas of the sphere where many firms are located. Concentrated areas are sparsely populated. Some regions of the product space have no firms residing there, as some text descriptions of products would describe products with no demand, such as the word combination: "eggs", "paint" and "gardening". The best way to tap the full research power of this product market grid is to use the Text-based Network Industry Classifications (TNIC), which is a network way of identifying competitors to each firm. Competitors are firms residing in close proximity in product space to each firm based on a continuous measure of similarity. Another key benefit of TNIC industries is that industry composition is updated annually, and our own research indicates that the product market space itself thus dynamically changes over time. As a result, static fixed-location FIC classifications miss out on much of the picture. Hoberg and Phillips Data Library

Welcome to the Hoberg-Phillips Data Library << NEW: Data extended to 2021 (overall coverage now 1989 to 2021)! >> Data provided by Gerard Hoberg (USC) and Gordon Phillips (Dartmouth) Text-based Network Industry Classifications (TNIC) data [click here] * These new industry classifications are based on firm pairwise similarity scores from text analysis of firm 10K product descriptions. Competitors are firm centric with each firm having its own distinct set of competitors - analogous to networks or a "Facebook" circle of friends. These new industry classifications are updated annually and offer more research flexibility, and are also more informative, than FIC (fixed industry) classifications such as SIC, NAICS, and the 10-K based FIC classifications below. Our research shows they sharply improve upon SIC and NAICS codes in explaining many different firm specific decisions, including firm profitability, Tobins Q and dividends. These benefits are outlined in Hoberg and Phillips (2010, 2016), with references available by clicking on above link. Industry Concentration and Total Similarity Data [click here] * HHI Concentration metrics and Total Similarity data is available based on TNIC Industries. Product Market Fluidity Data [click here] * Product Market Fluidity data assesses the degree of competitive threat and product market change surrounding a firm, and is based on Hoberg, Phillips and Prabhala (2014). Vertical TNIC Data (VTNIC) [click here] * Vertical TNIC data is comprised of two key databases, and is based on Fresard, Hoberg, and Phillips (2020). The first is a firm-year panel indicating the extent to which firms are vertically integrated. The second is a firm-pair-year database indicating the potential for vertical relatedness for every pair of firms in every year. Firm Scope Data [click here] * Scope data is comprised of two key databases, and is based on Hoberg, and Phillips (2024, Journal of Finance forthcoming). The first is a firm-year panel indicating the scope of each firm (number of product markets it operates in). The second is a firm-market-year database indicating the specific text-based markets each frim operates in for each year.
