Testing evolutionary theory of household consumption behavior in the case of novelty - a product characteristics approach

This article tests and extends the evolutionary theory of household consumption behavior, which is an alternative to neoclassical theory. Evolutionary economists offer novel approaches to the analysis of consumption behavior that emphasize the major role of learning in the evolution of consumer preferences and wants. As a possible inspiration for further progress in evolutionary thought, this paper examines the idea of consumer learning by studying the nature of what consumers should learn in the context of ‘novelty’. Our empirical results regarding novelty during the learning process show that consumers learn the ‘new characteristics’ of consumer goods, contrary to the Lancasterian approach, which suggests that the characteristics space of goods is fixed. We show that during the process of consumption, ‘consumer learning’ extends the characteristics space of consumer goods; this phenomenon is far from negligible and differs across product types. Moreover, our results show that the emergence of new characteristics cannot be modeled as a Poisson process because these new characteristics exhibit clear interdependence over time.     

WELFARE ENHANCING COORDINATION IN CONSUMER COOPERATIVES UNDER MIXED OLIGOPOLY

The recent globalization of world economies has led the retail markets of developed countries towards increasing levels of integration and strategic interdependence. A non negligible share of retail and food markets is currently served by co‐operative societies. Consistently with this trend, the consumer cooperatives have recently experienced increasing levels of integration. The main aim of this paper is to study the welfare effects of coordination among consumer cooperatives competing in quantities in a mixed oligopoly against profit‐maximizing firms. We show that, in absence of agency problems, under increasing or constant returns to scale a higher output coordination of the consumer cooperatives does not affect the total welfare as long as a nonnegative profit constraint holds in these firms. On the other hand, under decreasing returns to scale, the consumer cooperatives contribute more to social welfare when acting on behalf of all consumers. This is because, by coordinating consumers’ preferences, these firms can reduce their market output, thus helping the market to come closer to the first best. All together these results seem to provide an argument in favour of the recent process of integration involving consumer cooperatives in many developed countries.     

Equilibrium Effects of Superstition in the Housing Market

We investigate the interaction of product quality differentiation and consumer preference heterogeneity in durable goods markets, focusing on the effects of secondary market liquidity and consumer heterogeneity on equilibrium prices. We build an infinite‐horizon dynamic model of the apartments housing market that captures the above features. Some apartments are considered lucky, and some consumers are superstitious. Lucky apartments are valued more highly than non‐lucky ones only by superstitious consumers. Results show that the difference between the lucky apartment price and the non‐lucky apartment price becomes smaller when the secondary market becomes less liquid and when consumers’ preference heterogeneity becomes more persistent as opposed to time‐varying.     

A dynamical,pure exchange economy with feedback pricing

This paper examines a decentralized, dynamical, pure exchange economy in which changes in an individual consumers demand depend on his own consumption and on prices. An ‘instantaneous Walras law’ provides a sufficient condition for the existence of viable exchange trajectories. Such dynamic demand systems might result from goalseeking behavior of the March-Simon type, or when satisfaction of well defined preferences is continually improved through incremental adjustments in consumption. In contrast to Walrasian tâtonnement or Sinale's price adjustment model, prices in the present study follow a feedback control law that responds only to current consumer states. Various generalizations are also presented.     

Do Consumers Purchase Too Much Health Insurance? The Role of Market Power in Health‐Care Markets

Several authors have suggested that consumers purchase too much health insurance in private markets. We readdress this issue within a model that combines excess health‐care demand due to health insurance with market power due to monopolistic production of health‐care services. We evaluate the market equilibrium in terms of consumer welfare and social welfare. The consumer welfare criterion suggests that in the market equilibrium consumers in fact purchase too much health insurance coverage. The social welfare criterion, in contrast, suggests that because profits of the health‐care industry are properly accounted for, consumers should purchase more insurance coverage than they choose to do in the market equilibrium.     

Effects of income and social awareness on consumer WTP for social product attributes

Recent developments in environmental and animal welfare issues, and the introduction of new production practices may have affected consumer attitudes and preferences toward differentiated product choice. Factors such as animal well-being, environmentally friendly production, and the use of antibiotics appear to be increasingly core consumer concerns. We link the aforementioned with Maslow's hierarchy of needs suggesting that the higher income consumers should be more altruistic in their consumptive behavior and test this by evaluating consumer preferences for these attributes in pork chops. We also test whether social consciousness of the consumers translates into choice behavior. Data was obtained by choice experiment surveys and mixed logit estimation was used to estimate consumers' willingness-to-pay for the credence attributes. Results reveal that both, higher income and socially aware consumers are on average willing to pay higher premiums for the antibiotic-free attribute, but not for other two social attributes. Also, the group of higher income consumers is highly heterogeneous in their preferences, whereas socially aware consumers tend to be more homogeneous in their preferences.     

An econometric assessment of telecommunications prices and consumer surplus in Mexico using panel data

We analyze telecommunications prices in Mexico by using a panel data of countries similar to Mexico to estimate demand models for mobile and fixed-line telecommunications. We find that Mexico’s actual mobile and fixed-line prices are below the predicted prices based on similar countries’ prices. Mexican consumers are paying lower prices than what one would expect based on comparisons of comparable countries. We calculate that in 2011 Mexican consumers received at least $4–$5 billion (USD) in consumer surplus from these lower mobile prices and in 2010 they received over $1 billion (USD) in consumer surplus from these lower fixed-line prices. These findings are in contrast to the general perception that concentrated telecommunications markets in Mexico are resulting in high prices and harming consumers.     

TV advertising spillovers and demand for private labels: the case of carbonated soft drinks

The expansion of private labels, or store brands, has transformed consumer choice sets and competition in retail markets, prompting manufacturers to fight back with renewed pricing and product and promotion strategies to forestall further private label expansion. This article examines the spillover effects of television advertising on brand-level consumer demand for carbonated soft drinks (CSDs), including private labels, using a random coefficients logit model with household purchasing and advertising viewing Nielsen data. As in previous work, we find that although brand spillover effects significantly increase demand for CSD brands in the same company and undermine demand facing other manufacturers’ CSD brands, surprisingly, there are positive spillover effects on the demand for private label brands. This indicates that brand advertising is persuasive with respect to manufacturers’ brands but complementary with respect to private labels. Further results show that eliminating television advertising for CSDs would lower aggregate CSD sales as consumers migrate to other beverages, although private labels stand to gain, particularly Wal-Mart brands.     

The impact of socio-economic background on satisfaction: evidence for policy-makers

Consumer satisfaction with utility services has received increased attention from firms, consumer associations, regulators and governments since the 1990s. Evidence is mounting that consumers in specific socio-economic groups express lower satisfaction levels than their peers, at least, in some utility markets. Seeing this as part of their remit to protect consumer welfare, governments and international organizations are exploring possible demand-side policy responses with the intention of ameliorating lower satisfaction levels of these groups of consumers. However, more information on the precise relationships between satisfaction and consumers’ socio-economic background is required if policy is to be proportional and effective. This paper provides new empirical knowledge on this topic by contrasting consumers’ stated and revealed preferences for five utility services (electricity, gas, fixed and cellular telephony and Internet) across twelve European countries. We find strong evidence that consumers’ socio-economic characteristics matter: consumers with lower levels of education, the elderly and those not employed exhibit particular expenditure patterns on, and lower satisfaction levels with, some utility services. However, this relationship is uneven and depends on the socio-economic category and service in question. We conclude by highlighting five findings which may be of use to policy-makers when considering whether demand-side regulatory policies are required     

Time inconsistency and alcohol sales restrictions

Restrictions on alcohol sales hours or days are commonly used tools in order to reduce alcohol consumption. However, a forward-looking consumer can buy in advance, and thereby mostly undo the impact of the restriction. I study whether time inconsistent consumer preferences can provide a justification for restrictions on alcohol sales time. I estimate a demand model, which allows a fraction of consumers to be time inconsistent, using scanner data of beer purchases and other shopping behavior. According to the estimation results, 16% of regular beer buyers, or only 3% of all consumers, behave as if they are time inconsistent. I find that in terms of consumer welfare, the sales restriction may be welfare improving, but is worse than increasing taxes.     

Entry and market selection of firms: A laboratory study

We study how markets adjust to the entry of new firms under different conditions. Two incumbents face entry by three other firms. When firms’ costs are equal, entry always leads consumer surplus and profits to their equilibrium levels. When entrants are more efficient than incumbents, entry leads consumer surplus to equilibrium. With cost asymmetries, market behavior is satisfactory from the consumers’ standpoint but does not yield adequate signals to other potential entrants. Simultaneous entry is in the short run more favorable to consumers than sequential entry. A longer incumbency phase favors consumers after entry.     

Third-degree price discrimination,quality choice,and welfare

Employing an endogenous quality choice model, we reconsider the effect on welfare of monopolistic third-degree price discrimination. We prove that price discrimination always enhances welfare, mainly because the quality improvement owing to price discrimination increases consumer surplus. Moreover, we show that third-degree price discrimination benefits all parties, including consumers in the higher priced market if the preference differences between markets are sufficiently large.     

Free Trade Agreement with Endogenous Market Structure

We examine the incentives of free trade agreement (FTA) formation between two countries under endogenous market structure with leaders and followers. We demonstrate that establishing a FTA is neither an equilibrium outcome nor socially optimal when consumer demand and fixed cost are intermediate, products are close substitutes and countries are asymmetrical. This is because the FTA induces exit of followers, which makes the market less competitive and shrinks the leader’s production both in the domestic and foreign markets. We also show that large developing countries are less likely to establish a FTA than small developed countries.     

Social welfare and the unrepresentative representative consumer

If, for all prices, income distribution is optimal for a planner with a social welfare function, then aggregate demand is the same as that of a single “representative consumer” whose preferences over aggregate consumption are the same as the planner's. This paper shows that the converse is false. Aggregate demand may be the demand function of a representative consumer although the income distribution is not optimal for any social welfare function. The representative consumer may be Pareto inconsistent, preferring situation A to B when all the actual consumers prefer B to A. We give conditions under which existence of a representative consumer implies that the income distribution satisfies first order conditions for optimality. Satisfying the first order optimality conditions for an additively separable social welfare function is essentially equivalent to aggregate demand for every pair of consumers having a symmetric Slutsky matrix.     

Corporate Social Responsibility and International Competition: A Welfare Analysis

This paper examines the welfare implications of corporate social responsibility (CSR) in international markets under imperfect competition. Based on a stylized model of an import‐competing duopolistic market, we show the feasibility of moving toward tariff reductions when both domestic and foreign firms launch CSR initiatives in that their payoffs include not only individual profits, but also the benefits of consumers. For the case where the foreign exporter unilaterally adopts the consumer‐oriented CSR as a strategy, there is a rent‐shifting effect because the foreign firm's payoff increases whereas the domestic firm's profit decreases. In response, the importing country's government raises its tariff on the foreign product. If, instead, the domestic firm adopts the CSR strategy unilaterally, the rent‐shifting effect disappears and both the competing firms’ payoffs increase. We further identify the conditions under which the CSR initiatives of the firms constitute the dominant strategy, leading to a Pareto efficient outcome at which the firms’ payoffs, consumer surplus, and social welfare are at their maximum levels.     

Fashion’s Effect on Consumer’s Preference Formation

Abstract:

It is widely known that all principles of economics textbooks do not consider advertising much less fashion a demand determinant factor. Fashion’s effect on consumer choice is a critically important topic to the understanding of consumer behavior and decision-making in the “new economy.” The discussion of such issues includes verifying the effect of three important fashion market features on consumer preference formation and choice, namely the length of product life cycle, demand volatility, and impulse purchasing. It seems that time has come to concede that fashion firms, especially those producing fast or “junk” fashion, if you will, have successfully been affecting consumer preferences and have manipulated consumer choices for the sake of their own interests. Such a goal has been achieved by exploiting the fashion market features by employing specific marketing strategies, within the framework of supply chain agility, such as product remodeling, product customization, and revisions or innovation.     

MOVIES,MASS CONSUMERS,AND CRITICS: ECONOMICS AND POLITICS OF A TWO‐SIDED MARKET

Most analyses of the film market treat it as a single entity where producers make films based on average consumer interest while critics serve as forecasters or signalers of film quality to these consumers. We describe the film market as two‐sided—a mass market (average consumer) side and a high quality/artistic (cineaste) side—that each influence film maker production decisions and critical reviews as critics balance the preferences of mass market consumers and their own more artistic inclination. Using 1,824 films released during 2000–2014, we examine determinants of box office revenues and critical reviews, while addressing the overlap between them. Our results indicate that consumers and critics respond differently not only to film rating but also to film budgets, story sources, genre, and political content. We then use the dichotomy between average and high quality, artistic film consumers as a basis for understanding the normative views of the film markets relative to other two‐sided markets as well as the political economy of film regulation.

Price competition and innovation in markets with brand loyalty

Intuition suggests that in markets with consumer lock-in (‘brand loyalty’), firms with a large customer base earn higher profits. We show for a homogeneous goods duopoly that the intuition can be misleading, as the intensity of price competition depends on the initial market split. We derive mixed-strategy equilibria, and show that competition is often most intense when the market is split evenly. As a result, firms coordinate on an asymmetric split when consumers are not yet attached to firms. We also allow for asymmetric costs, and analyze when firms with a larger customer base are more eager to innovate.
