How Gen AI Is Transforming Market Research

Generative AI is revolutionizing market research by offering unprecedented ways to understand customers, assess competitors, and extend data-driven decision-making organizationally. Research with pioneering companies reveals four key opportunities: gen AI supports existing practices by making them faster and more scalable; replaces traditional methods with synthetic data that can match conventional results with greater accuracy; fills insight gaps by providing evidence for decisions previously based on intuition; and creates innovative applications like digital twins for testing customer interactions. Survey data shows 45% of market researchers already use gen AI, with most employing it to analyze transcripts and data. While acknowledging limitations around bias and representativeness, this framework helps business leaders navigate gen AI's transformative potential in gathering customer and market insights more efficiently and effectively than ever before.

Words That Matter: Analyzing the Causal Effect of Words

Authors
Alain Lemaire, Mingzhang Yin, and Oded Netzer
Date
April 4, 2025
Format
Working Paper

Language plays a crucial role in marketing, influencing outcomes such as consumer engagement and decision-making. Although prior research has extensively analyzed the relationship between linguistic features and business outcomes, most approaches have been descriptive or predictive, limiting their value for crafting more effective content. Understanding the causal effects of specific linguistic features is essential but challenging because, in real-world settings, the focal textual feature often changes simultaneously with other confounding factors.

We aim to stimulate discussion on how innovation research within marketing can use a better world (BW) perspective to help innovation become a driver of positive change in the world. In this "Challenging the Boundaries" series paper, we hope to provide purposeful research opportunities for scholars seeking to bridge innovation research with the BW movement. We frame our discussion with four areas of innovation research in marketing that are particularly relevant to BW objectives.

Personalized Game Design for Improved User Retention and Monetization in Freemium Games

One of the most crucial aspects and significant levers that gaming companies possess in designing digital games is setting the level of difficulty, which essentially regulates the user’s ability to progress within the game. This aspect is particularly significant in free-to-play (F2P) games, where the paid version often aims to enhance the player’s experience and to facilitate faster progression.

Language is a uniquely human trait at the core of human interactions. The language people use often reflects their personality, intentions and state of mind. With the integration of the Internet and social media into everyday life, much of human communication is documented as written text. These online forms of communication (for example, blogs, reviews, social media posts and emails) provide a window into human behaviour and therefore present abundant research opportunities for behavioural science.

Policy-Aware Experimentation: Strategic Sampling for Optimized Targeting Policies

Authors
Yi-Wen Chen, Eva Ascarza, and Oded Netzer
Date
December 4, 2024
Format
Working Paper

With unprecedented access to consumer information, firms are increasingly interested in designing highly effective data-driven targeting policies based on detailed consumer data. The current standard for implementing such policies involves the “test-then-learn” approach, where randomized experiments are used to estimate the differential impact of marketing interventions on various customers. However, this method fails to incorporate the firm’s ultimate business objectives, leading to inefficient experimentation and suboptimal targeting strategies.

One of the most significant levers available to gaming companies in designing digital games is setting the level of difficulty, which essentially regulates the user’s ability to progress within the game. This aspect is particularly significant in free-to-play (F2P) games, where the paid version often aims to enhance the player’s experience and to facilitate faster progression. In this paper, we leverage a large randomized control trial to assess the effect of dynamically adjusting game difficulty on players’ behavior and game monetization in the context of a popular F2P mobile game.

Quantitative Marketing and Economics
We introduce a probabilistic machine learning model that fuses customer click-stream data and purchase data within and across journeys. This approach addresses the critical business need for leveraging first-party data (1PD), particularly in environments with infrequent purchases, which are characterized by minimal or no prior purchase history.

As concern with climate change increases, people seek to behave and consume sustainably. This requires understanding which behaviours, firms and industries have the greatest impact on emissions.
