Joint pricing and design of urban highways with spatial and user group heterogeneity

This paper addresses the joint optimization of capacity investments and toll charges imposed on multi-group users in monopolistic private highways within general road networks. A game-theoretic formulation is provided that leads to a nonconvex bilevel program. The proposed modeling framework handles several complex issues raised in realistic applications, such as regulations on the levels of tolls and service, and the discrete nature of highway capacity, using a genetic optimization technique. Real-application results show the importance of considering the spatial heterogeneity of prices, and the tradeoff between investments and pricing strategies in regulated private highways.     

EXCHANGE RATE PASS‐THROUGH INTO RETAIL PRICES

We study exchange rate pass‐through and its determinants using scanner data on fast moving consumer goods sold by 1,041 outlets in the United Arab Emirates between 2006 and 2010. The data are augmented with country of origin information. Our main finding is that exchange rate pass‐through varies more across retailers within regions than across regions, and in particular that pass‐through increases with retailer market share. We also find that exchange rate pass‐through is negatively correlated with both product quality and the elasticity of substitution of the product category and positively correlated with the frequency of price adjustment.     

PROMETHEUS BOUND: POLARIZATION IS POSSIBLE IN THE NEOCLASSICAL GROWTH MODEL

The paper demonstrates that the standard neoclassical model of stochastic growth in the absence of any other modifications is consistent with club convergence contrary to the analysis in Cetorelli (2002, Journal of Economic Dynamics and Control, 27, pp. 29–50). In that sense, it is not necessary to augment the model with a probability of adverse shocks that is inversely related to aggregate capital stock or provide other modifications.     

Evolutionary game-theoretic model for dynamic congestion pricing in multi-class traffic networks

This paper describes an evolutionary game-theoretic learning model for dynamic congestion pricing in urban road networks, taking into account route choice stochasticity and reliability considerations, and the heterogeneity of users, in terms of their value of travel time and real-time information acquisition. The learning model represents the dynamic adjustments of users to travel cost changes which may take place in the day-to-day as well as the within-day timescales. The implementation into a simplified and a real urban road network signifies the important implications of modeling the dynamic and stochastic learning components of users’ behavior for accommodating the efficient deployment of congestion pricing schemes.     

Cancelling out early age gender differences in competition: an analysis of policy interventions

We study the willingness to compete of 588 children and teenagers aged ten to seventeen. We replicate the gender difference in tournament entry choices usually found in the literature for adults. We then show that policy interventions like quotas and preferential treatment help to close down the gender gap without leading to losses in efficiency, during or after a tournament. Given that differences in competitive behavior are prevalent from an early age, the application of interventions to promote females in competitions may be desirable already at early ages to promote equal chances for women on labor markets later on.     

LOCAL VERSUS PRODUCER CURRENCY PRICING: EVIDENCE FROM DISAGGREGATED DATA*

The pricing behavior of firms is a central issue in international macroeconomics. Using the introduction of the euro as a natural experiment I find that year‐to‐year volatility in import prices among Eurozone members diminished by 4% on average after the introduction of the euro. Additionally, I show that the magnitude of the drop was commensurate with the drop in exchange rate volatility. On the other hand, when looking at exports, I find that the introduction of the euro had no impact on export price volatility. The results support the hypothesis of producer currency pricing.     

Third-party punishment and counter-punishment in one-shot interactions

This paper presents experimental evidence from a simple three-person game showing that many individuals are willing to avenge third-party punishment in one-shot interactions. The threat of counter-punishment has a large negative effect on the willingness of third parties to punish selfish behavior. In spite of this, the extent of selfish behavior is identical to that in a treatment without counter-punishment opportunities. We discuss explanations for this puzzling finding.     

Marketing Chewing Gum: A Case Study of a Cypriot Company

The purpose of this article is to examine the issues related to the chewing gum marketing practices employed by a Cypriot company importing gum. Thus, the product, its target market, and competition are examined, a SWOT analysis is performed and the marketing mix is presented. Then the results are compared with the international market.

The case study method was employed to gain an initial understanding of the marketing practices employed by the company concerning the production of chewing gum.

The findings showed that the company offers a gum of superior quality, which in two years' time has captured a great share of a very competitive market. The company is giving special attention to the distribution and the promotion of the product.     

Micro-responses to shocks: pricing,promotion, and entry*

We study the market response to firm-specific demand shocks in a natural experiment setting. In 2006, a boycott of Danish products in several Arab countries was devastating for Danish cheese products firms. In Saudi Arabia, their market share collapsed from 16.5 percent in January to below 1 percent in March, and never fully recovered; by 2009, it was 6.3 percent. By analyzing micro-level (scanner) price and sales data, we find the following. (i) Danish firms lowered prices but kept the product mix the same. (ii) Non-Danish firms kept prices constant but changed their product mix by introducing new products and new product bundles. (iii) Non-Danish firms chose to introduce products that were similar to the Danish products in characteristic space in order to compete head-to-head. We complement the analysis with a theoretical framework that helps to account for our main findings.
