Consumer Shopping Behaviors and In-Store Expenditure Decisions
The authors study the effect that consumers’ adopted shopping patterns have on their responsiveness to pricing activity of retailers. Two important dimensions of shopping behavior — inclination to switch stores and preference for a particular retail price format (every day low price (EDLP) or promotional price (HILO)) are hypothesized to systematically affect the responsiveness of in-store expenditure decisions to changes in prices. In particular, store loyal households should be more responsive to changes in prices when deciding how much to buy in a given store. Similarly, the household shopping in a HILO format (where price variability is greater) should be more responsive. These hypotheses are developed and then tested using a joint model of store choice and in-store expenditure which accounts for potential interdependence between these decisions.
The findings attest to the ability of consumers to exploit variation in the environment: When constrained on one dimension (e.g., by shopping in only one store), consumers exhibit flexibility on another (e.g., by adjusting expenditures in response to price changes). If afforded the opportunity to be flexible (e.g., through variable prices at a HILO store), consumers take advantage of this. These aspects of shopping behavior interact in a theoretically interesting, but counter-intuitive way: the expenditure decisions of HILO switching consumers turn out to be the least responsive to changes in prices at a particular store. These shoppers exploit advertised price differences and move among stores. This responsiveness in the store choice decision means they have less incentive to exhibit flexibility in their expenditure decisions at a given store. The authors present estimates from a series of models calibrated on a scanner panel data set which captures store choices and expenditure receipts, and find all hypotheses to be supported
The Evolution of Equity Crowdfunding: Insights from Co-investments of Angels and the Crowd
Equity crowdfunding platforms are at the center of the digital transformation of early-stage venture funding. These digital platforms were originally heralded as a democratizing force in
early stage finance, due to their role in facilitating the exchange between entrepreneurs and a multitude of non-professional small investors (“the crowd”). Equity crowdfunding platforms
have experienced considerable growth and now attract professional investors including business angels. The presence of angels alongside the crowd on equity crowdfunding platforms
has raised questions whether these digital platforms can continue to play their role in democratizing access to capital. Using data from a leading equity crowdfunding platform, we examine the interplay between the investment decisions of angels and the crowd. We find evidence of information flows in crowdfunding platforms between angels, and from angels to the crowd. We find angels play an important role in funding of large ventures, whereas the
crowd not only fill the funding gaps for such large ventures but also play a pivotal role in the funding of small ones. The complementarity between angels and crowd investors seems to
increase the overall efficiency in an otherwise highly asymmetric and uncertain market, confirming that digitization can indeed bring important benefits to venture investment

Market Effects of Generic Entry: The Role of Physicians and of Non-Bioequivalent Competitors
Patent expiration represents a turning point for the brand losing patent protection as bioequivalent generic versions of the drug quickly enter the market at reduced prices. In this paper, we study how physician characteristics and their prescribing decisions impact the competition among molecules of a therapeutic class, once generic versions of one of these molecules enter the market. Specifically, we study the evolution of the Selective Serotonine Reuptake Inhibitors (SSRIs) after the introduction of generic versions of fluoxetine (brand name Prozac) in the United Kingdom (UK).
Our results suggest that, to fully understand the market evolution after generic entry, public health officials need to consider the marketing activities of pharmaceutical companies and determine how (1) individual physicians prescribe all competing drugs, and (2) respond to drug prices and marketing actions. For example, we find that a group of physicians sensitive to detailing switch from fluoxetine to non-bioequivalent branded alternatives after patent expiration, as Prozac significantly reduces its marketing support. Consequently, the market share of fluoxetine decreases despite being available at significant price discount under generic form, and despite the increase of prescriptions by price-sensitive physicians. Hence, governments interested in assessing generics diffusion should consider the prescribing across all competitors, whether or not bioequivalent, and determine the size of physician segments sensitive to pharmaceutical marketing activity and prices
Two years and ~196 million later: where is Choose and Book?
Background and objectives Introduced in 2004, Choose and Book was one of the National Programme for Information Technology's vanguard initiatives. It was to transform the old booking system by combining, for the first time, electronic booking with patient choice of their first hospital appointment. However, doctors' use of the system has been reported as being persistently low. This study, carried out in London, endeavoured to explore doctor's views about the system and to see how far it has progressed.
Method A questionnaire was devised and administered via an email invitation, to doctors. It was sent to 1800 and completed by 105 hospital consultants and general practitioners.
Results Most doctors thought that the concept of electronic booking itself was a good idea. The benefits that have been observed so far include an improvement in patient attendance at their appointments and the ability of doctors to track referrals. The biggest problems were described as an increased workload, technical problems and an uneven distribution of appointments between hospitals. In addition, most doctors thought that patient choice was a misguided concept in electronic booking and most reported that they were unsatisfied with Choose and Book overall.
Limitations The 6% response rate may make the results less likely to be representative of the whole survey population. The authors acknowledge this and have made recommendations as to how to more comprehensively test the objectives of this study, in future.
Conclusion In general, Choose and Book is still poorly perceived by doctors - particularly with respect to technical problems. There is still some support for the concept of electronic booking; however the patient choice element faces more resistance. Additional research is needed on this topic to further investigate the use of electronic systems in the health service

Will they come and will they stay? Online Social Networks and news consumption on external websites
This study explores the role of online engagement, homophily and social influence in explaining traffic and news consumption by social network users at an external news website. The authors jointly model visits and page views for a panel of users who registered with the news site using their Facebook accounts. In their model, the authors account for homophily using a latent space approach, and account for endogeneity, heterogeneity, and unobservable correlates. The results show that measures of an individual’s activity on Facebook are positively associated with that individual’s actions at the news site. In addition, knowing what a user’s Facebook friends do at the content website provides insights into a focal user’s behavior at that website, as visitors with friends who visit external news sites are more likely to visit the news website studied. In addition, news consumption (not just visits) also depends on friend’s actions but such an impact varies with the individual’s underlying browsing mode. We highlight the importance of social influence in news consumption and further show that homophily bias in news consumption is similar to prior research in other categories. Our study also highlights that visitors’ past browsing patterns are important predictors of future content consumption, although social network information significantly improves prediction beyond the effect of such more traditional behavioral metrics. Finally, we find that Managers can use readily available data for both prediction and targeting

Physicians' persistence and its implications for their response to promotion of prescription drugs
Motivated by the medical literature findings that physicians are inertial, we seek to understand (1) whether physicians exhibit structural persistence in drug choice (structural persistence occurs when the drug chosen for a patient depends structurally on the drug previously prescribed by the physician to other patients) and (2) whether persistence, if present, is a physician-specific characteristic or a physician state that can change over time. We further explore the role of promotional tools on persistence and drug choice, and we investigate whether physicians who exhibit persistence respond differently to three forms of sales promotion: one-to-one meetings (detailing), out-of-office meetings, and symposium meetings.
Our results show significant levels of physician persistence in drug choice. We find that persistence is mostly a cross-sectional physician feature. Nonpersistent physicians appear to be responsive to detailing and symposium meetings, whereas persistent physicians seem to be responsive only to symposium meetings. Out-of-office meetings, such as golf or lunch, have no effect on physicians' drug choice. We also find that (1) older physicians and those who work in smaller practices are more likely to be persistent and (2) physicians who are more willing to receive sales force representatives have a lower likelihood of being persistent. Finally, we discuss implications for public policy from our rich set of results
