On the fairness of airlines’ ticket pricing as a result of revenue management techniques

Pricing and availability of tickets have always been a source of confusion for customers in transportation industries. What is the best time to buy tickets? Why passengers taking the same flight might pay significantly different prices for the same seat? Why round trip tickets between two cities sometimes become cheaper than the one-way flights between them? Is it fair to buy a ticket for an itinerary cheaper than a ticket for just a part of it? These observations make customers wonder why they pay higher prices for shorter flights. In this paper, we study the airlines’ revenue management systems and explain some of these pricing schemes in travel industries. We develop a simulator to study the decision making process of network revenue management and use a numerical study to explore these questions and address some explanations for them. We relate these observations to the revenue management measurements such as the bid price or the adjustment cost and show how the dynamic of the network get influenced by these measures that eventually results in unusual pricing. We explain how a zero or small bid price of a specific leg may cause the price of an itinerary be cheaper than one segment of it and that the small bid price is caused by low demand in comparison to the available capacity. We exhibit network revenue management system and show the above issues for a small network.     

Horticultural exports,female wage employment and primary school enrolment: Theory and evidence from Senegal

In this paper we analyse the indirect effects of the boom in horticultural exports in Senegal on child schooling. The export boom has caused a dramatic increase in female off-farm wage employment, which led to increased female bargaining power in the household. We investigate the causal effect of female wage income on primary school enrolment. We develop a collective household model with endogenous bargaining power to show that, if women have higher preferences for schooling than men, the impact of female wage income on school enrolment will be the result of a positive income effect, a negative labour substitution effect and a positive empowerment effect. We address the question empirically using original household survey data from Senegal. We use different econometric techniques and show that female off-farm wage income has a positive effect on primary school enrolment for both boys and girls, and that female empowerment is specifically important for the schooling of girls. Our results imply that the horticultural export boom in Senegal has indirectly contributed to the second and third Millennium Development Goals of universal primary education and elimination of gender disparities in primary education.     

Part-time employment in Hong Kong: a gendered phenomenon?

In recent years, part-time employment in Hong Kong has grown considerably. Unlike Western industrialized countries where women play an overwhelming role in this form of employment, in Hong Kong a large proportion (44 per cent) of part-time workers are male. This study addresses the extent, patterns and trends in part-time employment in Hong Kong. In addition, it examines gender differences (such as age pattern, marital status, sectoral and occupational distribution) in this form of employment. Statistical analysis of survey data reveals that certain socio-demographic variables have differential effects on participation in part-time work for men and women. Finally, practical implications and future research directions are discussed.     

National culture and labour-market flexibility

This paper develops a cultural explanation for labour-market flexibility, building on the work of Lipset. Using Hofstede's conceptual framework for categorizing national cultures, certain hypotheses are derived concerning the association of various labour-market institutions and rigidities connected with employment, pay bargaining the treatment of the unemployed, and Hofstede's dimensions of national culture. These hypotheses are tested on data for OECD countries, using ordinary least squares regression. The results demonstrate a strong statistical association between Hofstede's cultural indices and the various labour-market rigidities. In particular, there is a strong inverse relationship between Hofstede's MAS variable and all our labour flexibility variables. Cultural values reflecting feminine gender structuring appear to be strongly associated with labour-market inflexibility. There is also a strong statistical association between scores on the UAI dimension, and employment rigidities and pay-bargaining practices. Cultural attitudes to power inequalities as reflected in the PDI index inversely related to rigidities in pay-bargaining practices. While the results demonstrate only statistical associations, they are suggestive of the possibility that culture plays more determining role. This has important implications for deregulation/regulation strategies.     

Ethnic factors and the use of public outdoor recreation areas: The case of Mexican Americans

Abstract

This study investigated the effects of subculture, marginality, and perceived discrimination on use of selected public outdoor recreation areas. The assimilation perspective from the sociology literature provided theoretical guidance for the study. These concepts were treated as different types of social distance (cultural distance, socioeconomic distance, and intergroup distance). Each was hypothesized to affect the use of outdoor recreation areas. Data for this analysis came from telephone interviews conducted with 1057 households in Maricopa and Gila counties in Arizona. The analysis was conducted using a subsample of respondents of Mexican ancestry. The results support the socioeconomic, or marginality, hypothesis. There was less support for the subcultural, or ethnicity, hypothesis. There was no support for the perceived discrimination hypothesis. Research implications and recommendations are discussed.     

Operational planning and competitive strategies of male and female retailers

Interest in the managerial practices of females in business has increased over the past decade due to women's increased representation in business. Anecdotal evidence has suggested that women approach decision making differently from men. The purpose of this study is to determine if gender differences regarding managerial strategies exist in the retail setting. Targeted managerial strategies focused on short-term planning processes (personnel, financial, inventory and market planning) and competitive strategies in operation (differentiation, cost leadership and focus). In a sample of 459 retailers from a twelve-state region, MANOVA was used to determine if significant differences in managerial strategies existed between genders. The data on retail competitive strategies suggest that men and women more likely than male business owners to recognize in the importance of differentiation and focus as retail competitive strategies in their business operations. Gender differences were also found in the operational planning areas of market and inventory planning.     

Unions and Gender Pay Equity in Academe: A Study of U.S. Institutions

This paper uses 1994-95 faculty salary data from over 1,100 four-year U.S. academic institutions, about one-fourth of them with collective bargaining agreements, to ask if faculty unions make a difference to gender pay equity. Average gender salary differences are negative at every rank and at every category of U.S. institution with or without collective bargaining agreement. Unions may improve gender salary differentials somewhat, particularly at the assistant professor level. There is no evidence that this gain will be lost at higher levels, and mixed evidence that further gains occur for women at the full professor level. The most pervasive and robust consequence of unions is to increase the positive impact that higher proportions of women at senior faculty ranks make on relative salaries at the assistant professor level. However, the influence of these higher-ranked women on gender salary inequalities at the associate and full levels is lower in union schools than nonunion schools. By reducing the flexibility of existing salary structures, collective bargaining apparently reduces the influence of senior women faculty on the salaries of current women faculty members while increasing their attention and influence at entry levels.     

Not Only Gender: More on Debating Markets

The paper by Gudeman and Gudeman on the nature of computer-mediated-communication (CMC) is a valuable contribution. This comment argues that they neglected one important aspect affecting CMC, namely ideology, and suggests that the ''Debating Markets'' exchange had long-term negative impacts on Femecon.
