Shopping values of clothing retailers perceived by consumers of different social classes

With the advent of diverse forms of retailing, competition among retailers is becoming more intense. Due to this phenomenon, retailers now require marketing strategies that can differentiate themselves from other retailers. However, there is a lack of research on what kind of shopping values consumers perceive from the retailers they visit. This paper analyzes dimensions of shopping values consumers perceive and variations in perceived shopping values according to the types of clothing retailers, be it a department store, discount store, or internet shopping mall. More specifically, the paper analyzes the moderating effect of consumers’ different social class in perceiving the shopping values of each retailer. The results show that shopping value consists of five major constructs: experiential, diversional, reliable, efficient, and self-expressive shopping values. We also found that consumers perceive more experiential, diversional, and reliable shopping values in department stores and internet shopping malls than in discount stores, and self-expressive shopping value is highly perceived in department stores. However, consumers’ social class can moderate the perception of shopping values for department stores and internet shopping malls, but not for discount stores. Discount store shopping is likely to provide consistent shopping values to consumers of all classes. Based on these findings, managerial implications are then presented.     

A comparison of diffusion approximations and actual limits in birth and death processes of noisy evolution

The stationary distribution of a birth and death process may not be approximated by a diffusion. The general situation is illustrated on the “musical chairs” model by Binmore et al. (1995). This model is shown to generate outcomes which are not captured by the concept of the ultralong run equilibrium selection introduced in Binmore et al. (1995).     

Learning Dynamics in Games with Stochastic Perturbations

Consider a generalization of fictitious play in which agents′ choices are perturbed by incomplete information about what the other side has done, variability in their payoffs, and unexplained trembles. These perturbed best reply dynamics define a nonstationary Markov process on an infinite state space. It is shown, using results from stochastic approximation theory, that for 2 × 2 games it converges almost surely to a point that lies close to a stable Nash equilibrium, whether pure or mixed. This generalizes a result of Fudenherg and Kreps, who demonstrate convergence when the game has a unique mixed equilibrium. Journal of Economic Literature Classification Numbers: 000, 000, 000.     

Determinants of interregional mobility in Russia

The paper studies the determinants of internal migration in Russia. Using panel data on gross region‐to‐region migration flows in 1992–99, we estimate the effect of economic, political and social factors. Although overall migration is rather low, it turns out that its intensity does depend on economic factors even controlling for fixed effects for each origin–destination pair. People move from poorer and job scarce regions with worse public good provision to those which are richer and prospering better both in terms of employment prospects and public goods. Migration is, however, constrained by the lack of liquidity; for the poorest regions, an increase in income raises rather than decreases outmigration. Our estimates imply that up to a third of Russian regions are locked in poverty traps.     

Is living in African cities expensive?

Although several studies have examined why overall price levels are higher in richer countries, little is known about whether there is a similar relationship at the urban and city level across countries. This paper compares the price levels of cities in Sub-Saharan Africa with those of other regions by analyzing price information collected for the purpose of calculating official purchasing power parities. The approach of the paper is to readjust the calculated price levels from national to urban levels, using known price-level ratios between those areas. The results indicate that African cities are relatively more expensive, despite having lower income levels. The price levels of goods and services consumed by households are 25 to 28 percent higher in Sub-Saharan Africa than in other low- and middle-income countries, relative to their income levels. Such high costs of living could constrain livelihood of low-income urban residents, as well as the development of Africa’s urban economies.     

Ukrainian gas transit game

This paper investigates the origins and reasons for the termination of the Russian natural gas flow from Russia to Europe through Ukraine in January 2009. It discusses the strategic interaction of the three players (Russia, Ukraine and the European Union) based on the dynamics of losses from confrontation. The objective is to interpret the situation in a stylized way and to derive outcomes using calibrated parameters for costs and benefits of the players. We show that the stakes are high for both Russia and Ukraine in choosing to follow their preferred strategies, as both countries would sustain moderate losses during the initial period of conflict. Meanwhile, Europe’s lack of reserves makes it less prepared for the energy deficit than Ukraine and Russia, causing wider and earlier suffering for European countries dependent on Russian gas. Therefore, the European Union has a strong incentive to intervene in the conflict. Its actions during the January confrontation between Ukraine and Russia included extortion and bribery, all of which affected the outcome of the conflict.
