Characterization of generalized weak orders and revealed preference

Summary This short paper provides an alternative framework to axiomatize various binary preference relations such as semiorder, weak semiorder etc. A set of simple axioms is presented in terms of revealed-preferred and revealed-inferior alternatives which makes the connection between various binary preference relations transparent; and every single axiom is necessary and sufficient for the existence of a binary preference relation of a specified type.We thank Bhasker Dutta, Peter Fishburn, Prasanta Pattanaik, Robert Russell and Thomas Schwartz for helpful suggestions     

Nostalgia,Identity and Tourism: Bollywood in the Indian Diaspora

In today's global world of movement our personal identities are changing. So, ‘where is my “home”?’ and ‘what is my “identity”?’ have become essential questions in one's life. In recent times, more and more diasporic communities visit their homelands, perhaps to reroot their identities. This study explored the influence of Bollywood movies in the Indian diaspora's identity construction and notions of home and tourism behaviour to India. Findings revealed that the Indian diaspora's imagination of India is strongly informed by Bollywood movies. Yet, different generations of the Indian diaspora have different reasons for travelling to India. The first generation's nostalgia arises from watching Bollywood movies, and as a result, creates a motivation to travel to India. The second generation's main to travel behaviour to India is to experience the new ‘modern’ country, portrayed in the affluent surroundings of contemporary Bollywood movies. And, for those first generations, who have never seen India before, Bollywood movies enable them to romanticise their homeland and create an urge to visit India. Thus, Bollywood movies have immense importance in the Indian diaspora's identity construction, promote diaspora tourism and constitute a huge opportunity for economic development.     

Drop-the-loser design in the presence of covariates

In the present work we develop a randomized two-treatment adaptive allocation design with covariates ensuring smaller variability of treatment allocations. We study, both numerically and theoretically, several exact and limiting properties of the design and consider an inferential problem following the allocation design. We compare the design with some of the existing allocation designs by computing its various performance measures.     

On the frontier between possibility and impossibility theorems in social choice

This paper attemts to make precise the frontier between possibility and impossibility theorems in social choice. It is shown that some criterion of rejection of some alternative is the critical factor. In the absence of such a condition, it is possible to construct a fairly wide class of “democratic” decision rules which satisfies a class of consistency conditions. Any one of these, together with the criterion of rejection, generates a power structure similar to the ones discovered by Arrow, Gibbard, and others when the decision rule is required to satisfy the weak Pareto principle and the independence condition.     

The return premiums to accruals quality

Using a battery of look-ahead-bias free measures of accruals quality (AQ), we find a strong and long-lasting negative relation between future returns and AQ. In decile portfolios that rank on AQ, a hedge portfolio that goes long in the lowest decile and short in the highest decile generates an annualized, risk-adjusted return of 4–12 % over 1-month to 5-year horizons, depending on the AQ measure and the portfolio weighting scheme. The return premiums associated with AQ are, (1) robust to a wide range of AQ measures, (2) robust to a battery of return-informative variables, and (3) not driven by low-priced or small stocks, earnings shocks, or the fourth-quarter effect. The documented premiums are consistent with the information uncertainty effect where firm uncertainty is negatively related to future returns.     

Situating the tourist gaze: from appropriation to negotiation

For decades, scholars have emphasized the power of the Western tourist gaze to construct Third World destinations as the ‘Exotic Other'. Scholars have also shown that ‘Third World’ tourism fuelled by media fantasies of the Other represents neo-colonization in the twenty-first century. However, considering all its intentions/claims of impartiality, tourism research has generally travelled in only one direction (from the West to the East). In this study, conducted in Goa and Puducherry, focusing on the social contexts in which people are viewed and photographed, we ask – what do the ‘Third World’ people think of Westerners gazing at them, and their surroundings? How do Western tourists react when photographed by domestic tourists? What are the power relations within which the photographer and the photographed are located? We recognize that no simplistic analyses are possible in the postcolonial context. Directing a critical lens at the tourist gaze, this essay moves from an understanding of the gaze as appropriating to that of the gaze as negotiated.     

Environmental uncertainty and managers’ use of discretionary accruals

Although an organization’s environmental uncertainty may induce greater variability in reported earnings, managers have incentives to reduce this variability. The flexibility accorded by generally accepted accounting principles (GAAP) provides managers the means to accomplish this via exercising discretion in recognizing accounting accruals. Thus, we examine the relation between managers’ use of discretionary accruals and environmental uncertainty. Overall, evidence suggests managers use discretionary accruals to reduce the variability in reported earnings more when firms operate in high uncertainty.     

Forests, biomass use and poverty in Malawi

Malawi is one of the poorest countries in Africa and has faced significant deforestation over the years. This paper seeks to examine the nature of the relationship between poverty and forests in Malawi. We try to answer three sets of questions: a) what is the extent of biomass available for meeting the energy needs of the poor in Malawi and how is this distributed? b) To what extent does fuelwood scarcity affect the welfare of the poor? And c) do households spend more time in fuelwood collection in response to scarcity? We answer these questions by matching household surveys with remote-sensing data.Our analyses suggest that biomass scarcity is associated with small but significantly lower household welfare, particularly for the rural poor. At current high levels of scarcity, 80% of rural poor households are likely to benefit from an increase in biomass in the community. Rural women spend more time on fuelwood collection where biomass is scarce. The small decrease in welfare associated with biomass scarcity suggests that households cope with scarcity in a variety of ways. Any effort to reduce degradation and deforestation in Malawi has to build on a clear understanding of household adaptation to fuelwood scarcity.
