Book excerpt: We propose a new likelihood-based estimation method for the sequential search model. By allowing search costs to be heterogeneous across consumers and products, we can directly compute the joint probability of the search sequence and the purchase decision when consumers are searching for the idiosyncratic preference shocks in their utility functions. Under this procedure, one recursively makes random draws for each dimension that requires numerical integration to simulate the probabilities associated with the purchase decision and the search sequence under the sequential search algorithm. We then present details from an extensive simulation study that compares the proposed approach with existing estimation methods recently used for sequential search model estimation, viz., the kernel-smoothed frequency simulator (KSFS) and the crude frequency simulator (CFS). In the empirical application, we apply the proposed method to the Expedia dataset from Kaggle which has previously been analyzed using the KSFS estimator and the assumption of homogeneous search costs. We demonstrate that the proposed method has a better predictive performance associated with differences in the estimated effects of various drivers of clicks and purchases, and highlight the importance of the heterogeneous search costs assumption even when KSFS is used to estimate the sequential search model. Lastly, from a managerial perspective, we show that sorting products by their expected utilities can enhance consumer welfare and increase the number of transactions.

Available in PDF, EPUB and Kindle. Book excerpt: The authors propose a new approach to simulate the likelihood of the sequential search model. By allowing search costs to be heterogeneous across consumers and products, the authors directly compute the joint probability of the search and purchase decision when consumers are searching for the idiosyncratic preference shocks in their utility functions. Under the assumptions of Weitzman's sequential search algorithm, the proposed procedure recursively makes random draws for each quantity that requires numerical integration in order to compute the joint probabilities of consumers' search and purchase decisions. In an extensive simulation study, the proposed method is compared with existing likelihood simulators that have recently been used to estimate the sequential search model. In addition, the proposed method recovers the consumers' relative preferences even if the utility function and/or the search cost distribution is mis-specified. The proposed method is then applied to online search data from Expedia for field-data validation. The more precise estimation of the model parameters and the improved prediction accuracy of the proposed approach stem from attributing researcher uncertainty in the search order to the consumer-product-level distribution of search costs and the randomness in the choice decision to the distribution of match values across consumers and products. From a substantive perspective, the authors find that search costs and "position" effects affect products in the lower part of the product listing page that are searched; more than they do those in the upper part of the page.

Book excerpt: We provide a detailed overview of the empirical implementation of the sequential search model proposed by Weitzman (1979). We discuss the assumptions underlying the model, the identifica-tion of search cost and preference parameters, the necessary normalizations of utility parameters, counterfactuals that require a search model framework, and different estimation approaches. The goal of this paper is to consolidate knowledge and provide a unified treatment of various aspects of sequential search models that are relevant for empirical work.

Available in PDF, EPUB and Kindle. Book excerpt: This paper studies advertising, price ceilings and taxes in a sequential search model with bilateral heterogeneities in production and search costs. We estimate equilibria using a genetic algorithm (GA) applied to over 100 market scenarios, each differing based on the number of firms, number of consumers, existence of price ceilings or taxes, costs of production, costs of advertising, consumers' susceptibility to advertising and consumers' search costs. We compare our equilibrium results to those of the standard theoretical consumer search literature and analyze the welfare effects of advertising, price ceilings and sales taxes. We find that price ceilings and uninformative advertising can improve welfare, especially if search costs are sufficiently high.

Available in PDF, EPUB and Kindle. Book excerpt: Dynamic stochastic general equilibrium (DSGE) models have become one of the workhorses of modern macroeconomics and are extensively used for academic research as well as forecasting and policy analysis at central banks. This book introduces readers to state-of-the-art computational techniques used in the Bayesian analysis of DSGE models. The book covers Markov chain Monte Carlo techniques for linearized DSGE models, novel sequential Monte Carlo methods that can be used for parameter inference, and the estimation of nonlinear DSGE models based on particle filter approximations of the likelihood function. The theoretical foundations of the algorithms are discussed in depth, and detailed empirical applications and numerical illustrations are provided. The book also gives invaluable advice on how to tailor these algorithms to specific applications and assess the accuracy and reliability of the computations. Bayesian Estimation of DSGE Models is essential reading for graduate students, academic researchers, and practitioners at policy institutions.

Download or read book Sequential Search with Refinement written by Yuxin Chen and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: We propose a structural model of consumer sequential search under uncertainty about attribute levels of products. Our identification of the search model relies on exclusion restriction variables that separate consumer utility and search cost. Because such exclusion restrictions are often available in online clickstream data, the identification and corresponding estimation strategy is generalizable for many online shopping websites where such data can be easily collected. Furthermore, one important feature of online search technology is that it gives consumers the ability to refine search results using tools such as sorting and filtering based on product attributes. The proposed model can coherently integrate consumers' decisions of search and refine. The model is instantiated using consumer clickstream data of online hotel bookings provided by a travel website. The results show that refinement tools have significant effects on consumer behavior and market structure. We find that the refinement tools encourage 34% more searches and enhance the utility of purchased products by 18%. However, most websites by default rank search results according to their qualities or relevance to consumers (e.g., Google). When consumers are unaware of such default ranking rules, they may engage in disproportionately more searches using refinement tools. Consequently, overall welfare surplus may deteriorate when search cost outweighs the enhanced utility. In contrast, if the website simply informs consumers that the default ranking already reflects product quality or relevance, consumers search less and the welfare surplus improves. We also find that refinement tools lead to a less concentrated market structure.

Download or read book The Economics of Search written by Brian McCall and published by Routledge. This book was released on 2007-12-20 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: The economics of search is a prominent component of economic theory, and it has a richness and elegance that underpins a host of practical applications. In this book Brian and John McCall present a comprehensive overview of the economic theory of search, from the classical model of job search formulated 40 years ago to the recent developments in equilibrium models of search. The book gives decision-theoretic foundations to seemingly slippery issues in labour market theory, estimation theory and economic dynamics in general, and surveys the entire field of the economics of search, including its history, theory, and econometric applications. Theoretical models of the economics of search are covered as well as estimation methods used in search theory and topics covered include job search, turnover, unemployment, liquidity, house selling, real options and auctions. The mathematical methods used in search theory such as dynamic programming are reviewed as well as structural estimation methods and econometric methods for duration models. The authors also explore the classic sequential search model and its extensions in addition to recent advances in equilibrium search theory.

Available in PDF, EPUB and Kindle. Book excerpt: Search Theory and Unemployment contains nine chapters that survey and extend the theory of job search and its application to the problem of unemployment. The volume ranges from surveys of job search theory that take microeconomic and macroeconomic perspectives to original theoretical contributions which focus on the externalities arising from non-sequential search and search under imperfect information. It includes a clear and authoritative survey of econometric methods that have been developed to estimate models of job search, as well as two lucid contributions to the empirical search literature. Finally, it includes a study that reviews and extends the literature on optimal unemployment insurance and concludes with an appraisal of the influence of search theory on the thinking of macroeconomic policymakers.

This book was released on 1989-02-24 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection of papers marks the development of empirical application of the search approach to labor economics--an approach which arose as a theoretical development of the 1960s and led to numerous insights in the 1970s. The search approach naturally incorporates uncertainty in the economic model, making up some of the early work in what is now called "the economics of information." Included are econometric issues such as estimation and specification of search models for wages and unemployment duration, continuous time models of turnover, and identification of structural parameters. Applications to policy questions including Unemployment Insurance and wage subsidy programs are given, and data collection issues are discussed within the search framework.
