The widely-used estimator of Berry, Levinsohn and Pakes (1995) produces estimates of consumer preferences from a discrete-choice demand model with random coefficients, market-level demand shocks and endogenous prices. We derive numerical theory results characterizing the properties of the nested...

Although typically overlooked, many purchase datasets exhibit a high incidence of products with zero sales. We propose a new estimator for the Random-Coefficients Logit demand system for purchase datasets with zero-valued market shares. The identification of the demand parameters is based on a...

Efficient, accurate, multi-dimensional, numerical integration has become an important tool for approximating the integrals which arise in modern economic models built on unobserved heterogeneity, incomplete information, and uncertainty. This paper demonstrates that polynomial-based rules...

Despite the importance of Berry et al.(1995)'s model of demand for differentiated products (BLP hereafter), there are few results about its finite sample behavior. In theory, simulation experiments provide a tool to answer such questions but computational and numerical difficulties have...

The latest World Press Trends report shows that business sentiment in the industry has taken a downturn, in a context where multiple challenges face news publishers around the world. Yet there are causes for optimism, as revenue diversification progresses and publishers double down on new...

This edition of WAN-IFRA’s annual flagship research and report reveals an industry challenged but optimistic about its business. It examines the results of publishers’ business in 2021, their forecasts for 2022 and beyond, and the trends and issues shaping the industry. Our research shows...

Since the industry standard approach to judge on the effectiveness of promotion is based on the impact on expected sales it cannot grasp other impacts in the distribution of future sales. Since retailers operate with very high strategic service level targets (e.g. 98%) high quantiles of the...

Information generated in online markets can affect both buyers’ and sellers’ expectations and therefore their choices. In this research, we investigate the effect of market information, generated in online auction markets, on buyers’ expectations and choices. To clear large inventories,...

The aim of this research was determining the factors of growth in the textile and food sector of Pakistan. The research study analyzed data from the financial statements of textile and food sector companies of Pakistan for the period 2013-17. A fixed effect regression model was used for...
