Globalization and Price Dispersion: Evidence from U.S. Trade Flows

Abstract

Historically, the integration of international markets has corresponded with decreasing prices for traded goods due to higher competition among suppliers, scale economies, and consumption demand. In recent years, product differentiation and multinational firm pricing behavior across markets and between suppliers make it difficult to assess the degree to which this still occurs. Using a confidential panel dataset comprising the universe of U.S. import trade transactions between 1992 and 2007, this paper explores the change in prices for imported commodities across American trade partners. Overall price dispersion appears to decline, albeit unevenly, over time; nevertheless, there is considerable heterogeneity within commodity groups, geographic regions, and income levels, which may owe to increased product and quality differentiation within commodity categories. Unusually, after controlling for gravity trade factors, trade openness and extensive measures of globalization are positively associated with price dispersion, which suggests a more disaggregated approach both at the commodity and firm level to account for these differences.

Document Tags and Keywords

Keywords Keywords are automatically generated using KeyBERT, a powerful and innovative keyword extraction tool that utilizes BERT embeddings to ensure high-quality and contextually relevant keywords.

By analyzing the content of working papers, KeyBERT identifies terms and phrases that capture the essence of the text, highlighting the most significant topics and trends. This approach not only enhances searchability but provides connections that go beyond potentially domain-specific author-defined keywords.
:
market, import, export, foreign trade, international trade, commodity, price, tariff, exporter, multinational, foreign, pricing, supplier, globalization, imported, trading, importer, custom

Tags Tags are automatically generated using a pretrained language model from spaCy, which excels at several tasks, including entity tagging.

The model is able to label words and phrases by part-of-speech, including "organizations." By filtering for frequent words and phrases labeled as "organizations", papers are identified to contain references to specific institutions, datasets, and other organizations.

Similar Working Papers Similarity between working papers are determined by an unsupervised neural network model know as Doc2Vec.

Doc2Vec is a model that represents entire documents as fixed-length vectors, allowing for the capture of semantic meaning in a way that relates to the context of words within the document. The model learns to associate a unique vector with each document while simultaneously learning word vectors, enabling tasks such as document classification, clustering, and similarity detection by preserving the order and structure of words. The document vectors are compared using cosine similarity/distance to determine the most similar working papers. Papers identified with 🔥 are in the top 20% of similarity.
