Same Question But Different Answer: Experimental Evidence on Questionnaire Design's Impact on Poverty Measured by Proxies

Based on a randomized survey experiment that was implemented in Malawi, the study finds that observationally‐equivalent, as well as same, households answer the same questions differently depending on whether they are interviewed with a short questionnaire or its longer counterpart. Statistically significant differences in reporting emerge across all topics and question types. In proxy‐based poverty measurement, these reporting differences lead to significantly different predicted poverty rates and Gini coefficients. The difference in poverty predictions ranges from 3 to 7 percentage points, depending on the model specification. A prediction model based only on the proxies that are elicited prior to the variation in questionnaire design yields identical poverty predictions irrespective of the short‐versus‐long questionnaire treatment. The results are relevant for estimating trends with questionnaires exhibiting inter‐temporal variation in design, impact evaluations administering questionnaires of different length and complexity to treatment and control samples, and development programs utilizing proxy‐means tests for targeting.     

The role of risk aversion in public goods dilemmas with environmental uncertainty: an experimental analysis

The purpose of this study is to extend earlier research on environmental uncertainty in public goods dilemmas. The present paper reports the results of an experiment designed to examine the effect of risk aversion on public goods provision. A von Neumann–Morgenstern utility function with constant coefficient of relative risk aversion is used to investigate the impact of risk attitudes within a threshold public goods environment. The outcome of the threshold public goods experiment shows that subjects are indifferent to the changes in environmental conditions. Additionally, the analysis indicates that risk aversion is a significant determinant of voluntary public goods contribution level.     

Twitter-marketing in multi-unit restaurants: Is it a viable marketing tool?

The main purpose of the current article is to investigate the status of the usage of Twitter-marketing and to examine the potential factors that impact the usage of Twitter-marketing. The results show that 69.4% of the multi-unit restaurant companies studied use Twitter-marketing and that small restaurants are more likely to utilize Twitter-marketing.     

An investigation of setup instability in non-stationary stochastic inventory systems

In stochastic inventory systems unfolding uncertainties in demand lead to the revision of earlier replenishment plans which in turn results in an instability or so-called system nervousness. In this paper, we provide the grounds for measuring system nervousness in non-stationary demand environments, and gauge the stability and the cost performances of (R,S) and (s,S) inventory policies. Our results reveal that, both the stability and the cost performance of inventory policies are affected by the demand pattern as well as the cost parameters, and the (R,S) policy has the potential to replace the cost-optimal (s,S) policy for systems with limited flexibility.     

The impact of advertising on consumer price sensitivity in experience goods markets

In this paper we use Nielsen scanner panel data on four categories of consumer goods to examine how TV advertising and other marketing activities affect the demand curve facing a brand. Advertising can affect consumer demand in many different ways. Becker and Murphy (Quarterly Journal of Economics 108:941–964, 1993) have argued that the “presumptive case” should be that advertising works by raising marginal consumers’ willingness to pay for a brand. This has the effect of flattening the demand curve, thus increasing the equilibrium price elasticity of demand and the lowering the equilibrium price. Thus, “advertising is profitable not because it lowers the elasticity of demand for the advertised good, but because it raises the level of demand.” Our empirical results support this conjecture on how advertising shifts the demand curve for 17 of the 18 brands we examine. There have been many prior studies of how advertising affects two equilibrium quantities: the price elasticity of demand and/or the price level. Our work is differentiated from previous work primarily by our focus on how advertising shifts demand curves as a whole. As Becker and Murphy pointed out, a focus on equilibrium prices or elasticities alone can be quite misleading. Indeed, in many instances, the observation that advertising causes prices to fall and/or demand elasticities to increase, has misled authors into concluding that consumer “price sensitivity” must have increased, meaning the number of consumers’ willing to pay any particular price for a brand was reduced—perhaps because advertising makes consumers more aware of substitutes. But, in fact, a decrease in the equilibrium price is perfectly consistent with a scenario where advertising actually raises each individual consumer’s willingness to pay for a brand. Thus, we argue that to understand how advertising affects consumer price sensitivity one needs to estimate how it shifts the whole distribution of willingness to pay in the population. This means estimating how it shifts the shape of the demand curve as a whole, which in turn means estimating a complete demand system for all brands in a category—as we do here. We estimate demand systems for toothpaste, toothbrushes, detergent and ketchup. Across these categories, we find one important exception to conjecture that advertising should primarily increase the willingness to pay of marginal consumers. The exception is the case of Heinz ketchup. Heinz advertising has a greater positive effect on the WTP of infra-marginal consumers. This is not surprising, because Heinz advertising focuses on differentiating the brand on the “thickness” dimension. This is a horizontal dimension that may be highly valued by some consumers and not others. The consumers who most value this dimension have the highest WTP for Heinz, and, by focusing on this dimension; Heinz advertising raises the WTP of these infra-marginal consumers further. In such a case, advertising is profitable because it reduces the market share loss that the brand would suffer from any given price increase. In contrast, in the other categories we examine, advertising tends to focus more on vertical attributes.

Dynamic Influences on Individual Choice Behavior

Research examining the process of individual decision making over time isbriefly reviewed. We focus on two major areas of work in choice dynamics:research that has examined how current choices are influenced by the historyof previous choices, and newer work examining how choices may be made toexploit expectations about options available in the future. A central themeof the survey is that if a general understanding of choice dynamics is toemerge, it will come through the development of boundedly-rational models ofdynamic problem solving that lie on the interface between economics andpsychology.     

The role of the Internet in physician-patient relationships: The issue of trust

The Internet has proven to be a powerful and very popular vehicle for distributing health information to millions of individuals; it is interactive, user-controlled, and provides an effective means for communicating detailed information. While there has been increasing use of the Internet in healthcare, little research has been conducted to examine what, if any, impact the availability and integrity of healthcare information on the Internet has on the physician-patient relationship. Importantly, several studies show that Web-based health information frequently contains inaccurate or incomplete information. Patients who retain such information go so far as to suggest approaches to their physicians and express disappointment when the physicians refuse to prescribe as expected. For their part, doctors are concerned about the physician-patient relationship when they have to explain to patients that their Internet-based information is less than accurate; consequently, the physician-patient relationship is often affected. While many issues bear upon the physician-patient relationship, the central one is trust. This article examines consumer use of the Internet for healthcare information, considers the problems caused by inaccuracies or omissions from third party websites, and sets forth recommendations regarding how the Internet can be used to improve the physician-patient relationship. It is hoped that these suggestions provide a better understanding of the required components of upcoming healthcare strategies.
