A distribution-free newsvendor model with balking and lost sales penalty

In this paper, we extend the classical single period newsvendor model in an environment of customer balking, which occurs when customers are reluctant to buy a product if its available inventory falls below a threshold level. Since failure to make a sale usually results in a cost penalty, in addition to the opportunity cost of lost sales, we incorporate such costs in our model. Furthermore, we extend our model to include fixed ordering costs. Our analysis is based on the assumption that only the mean and the variance of the distribution of demand are known, without assuming any specific distributional form. We illustrate the concepts developed here through simple numerical examples and demonstrate the effectiveness of our approach by solving a set of 1000 randomly generated test problems.     

Fixed-step anonymous overtaking and catching-up

We investigate criteria for evaluating infinite utility streams that satisfy fixed-step anonymity and include some notion of overtaking or catching-up. We do so in a generalized setting that does not require us to specify the underlying finite-dimensional criterion (e.g. utilitarianism or leximin). We present axiomatizations that rely on weaker axioms than those in the literature, and which in one case is new. We also provide a complete analysis of the relationships between the symmetric parts of these criteria and likewise for the asymmetric parts.     

Implied volatility and future portfolio returns

Prior studies find that the CBOE volatility index (VIX) predicts returns on stock market indices, suggesting implied volatilities measured by VIX are a risk factor affecting security returns or an indicator of market inefficiency. We extend prior work in three important ways. First, we investigate the relationship between future returns and current implied volatility levels and innovations. Second, we examine portfolios sorted on book-to-market equity, size, and beta. Third, we control for the four Fama and French [Fama, E., French, K., 1993. Common risk factors in the returns on stocks and bonds. Journal of Financial Economics 33, 3–56.] and Carhart [Carhart, M., 1997. On persistence in mutual fund performance. Journal of Finance, 52, 57–82.] factors. We find that VIX-related variables have strong predictive ability.     

Rural-urban migration and family ties: an analysis of family considerations in migration behaviour in India

The importance of family considerations in mobility decisions of rural to urban migrants in India was investigated by analyzing evidence on urban rural ties. The empirical basis was a survey of migrant heads of households in Delhi conducted from October 1975 to April 1976. Only 14% of the migrants in the sample were accompanied by family members when they moved to Delhi, and at the time of the survey 44% of the sample were living on their own as nonfamilial households. 82% of the migrants reported having family members living in the area. In 1/3 of these cases the rural household contained the wife of the migrant. Over 3/4 of the sample visited their origin regularly, and 2/3 were sending money. Migration decisions are discussed in the context of the mutlicentered family, and urban rural family links are classified into several distinct types, and the importance of visits and remittances to origin for each of these types are investigated. An econometric analysis of conjugal separation is presented, and the determinants of remittances are investigated. The salient methodological innovations are a 7-part typology of urban rural familial links and the use of logit analysis in the identification of the important determinants of conjugal separation. Nearly 4/5 of the migrants visited their place of origin. The proportion reporting visits was higher for migrants who had family members at place of origin, but as many as 60% of the migrants not having family links maintained contact with rural residents through visits. If migrants recognized mutual kinship rights and obligations dictated by the social system, they maintained close functional ties with their kin. Only 56% of unmarried migrants living as nonfamilial units reported visits to origin compared to 92% of those living with their nuclear unit. For migrants who reported presence of family members at origin, there was no significant difference between landowners and nonlandowners in the proportion who reported visits. Married migrants who had left their wives in the rural area were more likely to visit origin during the agricultural busy periods. A majority of the migrants maintained economic links with the rural area, and in early all these cases financial flows were from the urban to the rural area. Remittances tended to be related positively to urban earnings and needs of the rural household and negatively to obligations in the urban household. There was no evidence of ties weakening over time, but migrants who planned to settle in the city remitted less. To an extent conjugal separation was temporary and reflected husbands and wives making the journey at different times. Migrants were also inhibited from bringing their wives to the city if they owned land at origin or had migrated to obtain cash for specific needs. A part of the explanation also lies in varying regional cultural and environmental characteristics.     

Foreign capital inflow,skilled–unskilled wage inequality and unemployment of unskilled labour in a fair wage model

This paper has developed a three-sector general equilibrium framework that explains unemployment of both skilled and unskilled labour. Unemployment of unskilled labour is of the Harris–Todaro (1970) type while unemployment of skilled labour is caused due to the validity of the FWH in the high-skill sector. There are two types of capital one of which is specific to the primary export sector while the other moves freely among the different sectors. Inflows of foreign capital of either type unambiguously improve the economic conditions of the unskilled working class. However, the effects on the skilled–unskilled wage inequality and the extent of unemployment of both types of labour crucially hinge on the properties implied by the efficiency function of the skilled workers.     

From information technology to bioinformatics: Evolution of technological capabilities in India

This paper explores a trend in the development of innovation in emerging economies: exaptive technological capabilities. A growing proportion of innovation is originating in emerging economies that, being resource-constrained in a dynamic and uncertain environment, requires leveraging existing capabilities and recombining with new knowledge resources. An evolutionary biology model is applied to a process model whereby initial technological capabilities are renewed by the firm given an external selection event. Using a detailed case study across 6 years, this paper investigates the exaptation process of Information Technology (IT) capabilities into bioinformatics by an Indian IT firm, Tata Consultancy Services (TCS). Findings suggest that just leveraging existing technological capabilities alone is a model set for failure. Such a tactic ignores the environment of the new technology application area. By investing in the needed complementary resources, TCS corrected its initial path to open source their software and offer consulting services on how to utilize the software and, thus, create intellectual property. These insights are valuable not only for the innovation management of traditional IT services to life sciences, but more broadly for firms in emerging economies that hope to renew and build exaptive technological capabilities to enter unforeseen new application areas by leveraging existing technological capabilities.     

Nature of comovements in US state and MSA housing prices

This study analyzes the time-varying nature and determinants of comovements in US housing prices using state and metropolitan statistical area (MSA) data. We employ dynamic factor models with time-varying loadings and stochastic volatility (DFM-TV-SV) to estimate the national, regional, and state factors. The time-varying factor loadings and stochastic volatility features enrich the dynamic factor model structures and are an effective tool to examine the comovements in housing prices. We find that the national factor is the dominant factor in explaining the movement of housing prices. The national factor accounts for 79% of the variation in state-level housing prices on average, with the greatest magnitude occurring during the housing boom and bust periods in many regions and states. We also find that the factors and synchronization effects are time-varying and heterogeneous across regions. The state-level housing prices contain higher national housing factor components in states with more diverse economies, higher wages and house prices, and lower unemployment rates. These findings shed light on the effectiveness of residential real estate diversification across the United States and the potential for elevated national housing risk amid economic downturns due to increased national housing price integration.     

Meaning-oriented consumption: A systematic review and research agenda

The quest for finding meaning in life is central to human existence. Evidence supporting consumption as a source of meaning in life is scant and lies in discrete studies across multiple disciplines. We call consumption that engenders a sense of meaning in life ‘meaning-oriented consumption’. In this paper we conduct a systematic literature review of 102 papers, using the Scientific procedures and rationales for systematic literature reviews (SPAR-4-SLR) (Paul et al. (2021). International Journal of Consumer Studies, 45(4)). We draw on the theory of meaning in life to arrive at a theoretically grounded conceptualization of meaning-oriented consumption. We discuss the antecedents and consequences of meaning-oriented consumption, categories and processes that make consumption meaningful. We gather insights into the relationship between hedonic and meaning-oriented consumption. Finally, we identify knowledge gaps in theory, context, constructs and methodology. This review identifies several consumption contexts and situations that offer potential for marketers to design meaningful offerings.     

Technology selling and innovation with bargaining

We examine when the price of technology is found through bargaining between the seller and the buyer and explore its effect on the innovation incentive. Selling the technology is preferred to licensing for the innovating firm. The possibility of selling increases the incentive for innovation compared to licensing for a range of high‐cost innovation, but reduces the incentive for a range of low‐cost innovation.
