The effects of store brand loyalty on store loyalty: evidence from the Spanish market

This article studies the impact of retailers' store brands on store performance. Specifically, we analyze the extent to which store brands contribute to store loyalty. On the one hand, a positive relationship between customers' familiarity with and loyalty to the retailer's own brand and customers' loyalty to the retailer should result from the potential of the store brand to differentiate the retailer. On the other hand, an negative relationship between customers' familiarity with and loyalty to the retailer's own brand and customers' loyalty to the retailer may result from store brands' association with more price-sensitive customers, who have a higher propensity to buy at different stores that offer the best bargain. The empirical analysis, conducted with a sample of customers of leading retailers in the Spanish detergent market, shows no relationship between store brand loyalty and loyalty to the retailer. Although the purchase of store brands relates positively to higher loyalty to the retailer, this relationship deteriorates with the degree of exclusivity of store brands within the customer's shopping basket.     

Can the North–South trade regime explain intra- and inter-country productivity differences?

The literature identifies North–South disparities in Total Factor Productivity (TFP), which, in turn, justify the bulk of international income differences. By building a dynamic, general equilibrium model of North–South technological-knowledge diffusion with scale-invariant growth, we extend the literature in several directions: (i) growth is driven by Schumpeterian R&D and by high and low-skilled human-capital accumulation; (ii) three trade regimes are considered; (iii) sectoral and aggregate TFP measures are computed; (iv) the extent to which the North–South trade regime explains intra-country TFP and inter-country TFP differences is evaluated. In particular, the results suggest that intra-country TFP differences increase and inter-country TFP differences fall when countries are more interdependent.     

Decentralized trade, random utility and the evolution of social welfare

We study decentralized trade processes in general exchange economies and house allocation problems with and without money. The processes are affected by persistent random shocks stemming from agents’ maximization of random utility. By imposing structure on the utility noise term—logit distribution—one is able to calculate exactly the stationary distribution of the perturbed Markov process for any level of noise. We show that the stationary distribution places the largest probability on the maximizers of weighted sums of the agents’ (intrinsic) utilities, and this probability tends to 1 as noise vanishes.     

Economic performance and international trade engagement: the case of Portuguese manufacturing firms

By combining economic and financial data for Portuguese manufacturing firms with data on their exports and imports, we uncover some aspects of the relationship between international trade engagement and firms’ performances. In line with recent theoretical and empirical developments in the international trade literature: (i) we testify that Portuguese international trade is highly concentrated, especially on the import side, and both in inter- and intra-sector terms; (ii) we corroborate previous studies and theses according to which two-way traders outperform only importers, only exporters and above all domestic firms; (iii) we find that the greater the diversification of markets and goods (especially with regard to imports), the better the performance achieved by internationalised firms; (iv) we notice that the higher the intensity of firms’ international trade (especially imports), the better their performance; (v) we also present evidence that destination markets for exports and origin markets for imports are also important in explaining firm’s performance.     

Bargaining, coalitions and competition

We study a Gale-like matching model in a large exchange economy, in which trade takes place through non-cooperative bargaining in coalitions of finite size. Under essentially the same conditions of core equivalence, we show that the strategic equilibrium outcomes of our model coincide with the Walrasian allocations of the economy. Our method of proof makes use of the theory of the core. With respect to previous work, our positive implementation result applies to a substantially larger class of economies: the model relaxes differentiability and convexity of preferences, and also admits an arbitrary number of divisible and indivisible goods.

Does Teacher Subject Knowledge Contribute to Student Academic Performance in Developing and Least Developed Countries?

Little is known about the causal impact of teacher knowledge on student performance. In this research paper we intend to approach the potential causal effect (i.e. going beyond correlation) of sixth grade teachers’ knowledge on their students’ academic achievement for three Sub-Saharan African countries. To achieve this, we have used the heterogeneity of teachers’ subject knowledge and students’ correspondent academic achievement within-student between-subjects using student fixed effects. Concretely, our work is based on previous research by Bietenbeck, Piopiunik and Wiederhold. Compared to them, we do not use countries that lack representative information after keeping only those students taught by the same teacher for the subjects under analysis. This enables us to obtain more reliable results on this issue. Our results indicate that teacher subject knowledge in reading and mathematics does not have a significant influence on student academic achievement in these subjects for the countries under scrutiny. Many robustness checks have corroborated this conclusion, which contrasts with the positive effect found by Bietenbeck, Piopiunik and Wiederhold.     

Savings that hurt: Production rationalization and its effect on prices

Postmerger scenarios often lead to a reallocation of resources and production across the merged entity. Production rationalization, the process of reallocating production across facilities so as to reduce total costs, results in firms equating marginal costs across markets. This results in marginal costs, and hence prices, being higher in some markets and lower in others than otherwise would be without production rationalization. This paper proposes a model of competition that elicits these effects and the resulting consequences on consumer and producer surplus. The paper also presents empirical evidence to show that production rationalization, in the form of fleet reoptimization, affected prices following the US Airways/American Airlines merger. Prices of the merged firm increased 10% on routes typically served by US Airways relative to routes typically served by American Airlines, and by 12% relative to US Airways’ rivals’ prices. Price‐cost regressions confirm such price hikes were likely due to fleet reoptimization.     

Epistemic Conditions for Equilibrium in Beliefs without Independence

Aumann and Brandenburger [Econometrica63(1995), 1161–1180.] provide sufficient conditions on the knowledge of the players in a game for their beliefs to constitute a Nash equilibrium. They assume, among other things, mutual knowledge of rationality. By rationality of a player, it is meant that the action chosen by him maximizes his expected utility, given his beliefs. There is, however, no need to restrict the notion of rationality to expected utility maximization. This paper shows that their result can be generalized to the case where players' preferences over uncertain outcomes belong to a large class of non-expected utility preferences.Journal of Economic LiteratureClassification Numbers: C72, D81.     

Reflections from Employers on the Disabled Workforce: Focus Groups with Healthcare,Hospitality and Retail Administrators

Historically, employment rates for people with disabilities have been low. Despite legislation that prohibits the discrimination of this group in work settings, employers are reluctant to hire people with disabilities. The purpose of this qualitative study was to explore the experiences of employers with workers with disabilities. Three focus groups were conducted with 21 administrators from three business sectors (i.e., healthcare, hospitality, and retail). Content analysis indicated five primary themes: (1) importance of disability employment agencies and disability advocates; (2) persistence of manager bias; (3) lack of promotion opportunities; (4) costs associated with having workers with disabilities; and (5) benefits associated with having workers with disabilities. Implications include the need for intervention studies that address the challenges experienced by individuals with disabilities, particularly during hiring and promoting phases of employment, and educational efforts to inform administrators and managers of the few costs and numerous benefits associated with having workers with disabilities.
