1 Introduction The empirical measurement of long-run (or “carry-over”) effects from marketing effort is a central topic in marketing. A long literature has sought to measure these carry-over effects empirically and to assess their relevance to marketing decision making. These efforts have led to several interesting stylized facts. For example, advertising and prices exhibit carry-over effects on future prices and sales (Assmus et al. 1984; Kalyanaram and Winer 1995, respectively). Similarly, the Bass (1969) diffusion model predicts a pattern of new product diffusion that has been replicated in many industries. Finally, market shares in many product categories are found to be mean and covariance-stationary over time, suggesting the emergence of a long-run equilibrium (Dekimpe and Hanssens 1995). In this discussion piece, we advance this literature on long-run effects by elaborating upon microeconomic theories to explain these dynamic phenomena. We also examine normative applications to recommend improved marketing policies based on structurally estimating models derived from th
