Fashionable food: a latent class analysis of social status in food purchases

A framed field experiment combined with a latent class econometric approach was used to investigate how prestige-seeking behaviour influences food choices. We propose a theoretical framework to test conspicuous consumption of specialty food products. We test the hypothesis empirically by categorizing individuals into unobserved latent classes according to their general prestige-seeking behaviour. We find evidence of food consumption driven by prestige to the point of becoming a symbol of social status. The prestige-seeking behaviour seems to be motivated by invidious comparison or higher-class individuals seeking to differentiate themselves from lower-class individuals; and pecuniary emulation, or lower-class individuals buying prestigious goods in order to be perceived as members of a higher class. Findings from this study revealed that the effects of differentiating labelling attributes had a higher impact for individuals classified into classes with prestige-seeking behaviour to attain an elevated social status.     

On the use of flexible mixing distributions in WTP space: an induced value choice experiment

In this study, we use data from an induced value choice experiment to compare estimates from mixed logit models in willingness to pay (WTP) space using different parameter distributional assumptions. Specifically, we test differences in WTP estimates when using flexible parameter mixing distributions (i.e. Legendre polynomials, step functions and splines) and conventional parameter distributions (normal and lognormal). Similar WTP estimates are obtained. However, we observe that WTP estimates are statistically different from the induced value when conventional distributions are assumed, but they are not when more flexible distributions are assumed. This suggests that flexible distributions can provide more reliable WTP estimates.     

Invariance of conditional maximum utility

The consumer benefit in a discrete choice model is often measured by maximum utility. We characterize the conditional (on the chosen alternative) and the unconditional distribution of maximum utility. We show that among a wide class of distributions (independent with convex supports) of error terms, the Type I extreme-value distribution is the unique distribution which ensures that all the conditional distributions of maximum utility coincide. Moreover, we show that for i.i.d. (with convex support) error terms, the invariance of conditional expected maximum utility characterizes the multinomial logit model.     

Hybrid Choice Models: Progress and Challenges

We discuss the development of predictive choice models that go beyond the random utility model in its narrowest formulation. Such approaches incorporate several elements of cognitive process that have been identified as important to the choice process, including strong dependence on history and context, perception formation, and latent constraints. A flexible and practical hybrid choice model is presented that integrates many types of discrete choice modeling methods, draws on different types of data, and allows for flexible disturbances and explicit modeling of latent psychological explanatory variables, heterogeneity, and latent segmentation. Both progress and challenges related to the development of the hybrid choice model are presented.     

RESTORING THE PRINCIPLE OF MINIMUM DIFFERENTIATION IN PRODUCT POSITIONING

Most research on product positioning supports the idea of differentiation. Product standardization (i.e., minimum differentiation) occurs only under very limiting assumptions. Yet, similar products are often observed in the marketplace. We attempt to restore the case for standardization by using more realistic assumptions than in previous work. We assume that consumers consider not only observable attributes in brand choice, but also attributes that are unobservable by the firms. We find that standardization is an equilibrium when consumers exhibit sufficient heterogeneity along the unobservable attributes under both positioning with exogenously given prices and price competition, We also show that, under insufficient heterogeneity along the unobservable attribute, our results coincide with past research that argues in favor of differentiation.     

Price Dispersion and Consumer Reservation Prices

We describe firm pricing when consumers follow simple reservation price rules. In stark contrast to other models in the literature, this approach yields price dispersion in pure strategies even when firms have the same marginal costs. At the equilibrium, lower price firms earn higher profits. The range of price dispersion increases with the number of firms: the highest price is the monopoly price, while the lowest price tends to marginal cost. The average transaction price remains substantially above marginal cost even with many firms. The equilibrium pricing pattern is the same when prices are chosen sequentially.     

Consequential egalitarianism vs. accountability principle: an experimental investigation

We conducted a laboratory experiment to investigate how people’s fairness views and redistribution depend on different rooted risks, specifically whether the risk is exogenously assigned in a ‘pure-luck’ control assignment or endogenously chosen by subjects in an ‘option-luck’ treatment. This experiment examines two contradictory views about distributive justice, namely consequential egalitarianism and the accountability principle (AP). The results show widespread support for the view of AP when participants have the opportunity to alleviate the risks.     

Sailing away from Malthus: intercontinental trade and European economic growth, 1500–1800

What was the contribution of intercontinental trade to the development of the European early modern economies? Previous attempts to answer this question have focused on static measures of the weight of trade in the aggregate economy at a given point in time, or on the comparison of the income of specific imperial nations just before and after the loss of their overseas empire. These static accounting approaches are inappropriate if dynamic and spillover effects are at work, as seems likely. In this paper, I use a panel dataset of 10 countries in a dynamic model that allows for spillover effects, multiple channels of causality, persistence, and country-specific fixed effects. Using this dynamic model, simulations suggest that in the counterfactual absence of intercontinental trade, rates of early modern economic growth and urbanization would have been moderately to substantially lower. For the four main long-distance traders, by 1800, the real wage was, depending on the country, 6.1–22.7 % higher, and urbanization was 4.0–11.7 percentage points higher, than they would have otherwise been. For some countries, the effect was quite pronounced: in The Netherlands between 1600 and 1750, for instance, intercontinental trade was responsible for most of the observed increase in real wages and for a large share of the observed increase in urbanization. At the same time, countries which did not engage in long-distance trade would have had real wage increases in the order of 5.4–17.8 % and urbanization increases of 2.2–3.2 percentage points, should they have done so at the same level as the four main traders. Intercontinental trade appears to have played an important role for all nations that engaged in it, with the exception of France. These conclusions stand in contrast to the earlier literature that uses a partial equilibrium and static accounting approach.

Utilitarianism and fairness in portfolio positioning

The paper introduces the theory of optimal positioning of financial products. It is illustrated in the context of long-term intertemporal portfolio allocation and can be applied for example to asset allocation funds. We embed this problem in location theory: the portfolio is optimized within the investors’risk aversion dimension. For the CRRA utility functions, we compute explicitly the distance functions. For the first (utilitarian criterion), the average utility of the investors is maximized. For the second one (fairness criterion), the choice of portfolio is optimized so that the average monetary loss due to the lack of customization is minimized. Given the distribution of investors’ risk aversion, we provide a solution method and an algorithm to optimally position standardized portfolio along one of these two criteria.
