The Seven Faces of Singaporeans: A Typology of Singapore Consumers and Their Aspirations and Life Satisfaction

A large-scale representative survey was conducted to examine lifestyle patterns of Singaporeans. The data were analyzed using a three-step approach. First, the underlying dimensions of Singaporeans' value system were identified using factor analysis. Based on 45 lifestyle and value items, six factors were obtained. The analysis suggests that the value system of Singaporeans can be described using the following six factors: (1) family values, (2) entrepreneurial spirit, (3) status, (4) traditional values, (5) materialism, and (6) society orientation. Second, these six factors were then utilized to identify clusters of Singaporeans with similar value profiles. The cluster analysis identified the following seven major groups of Singaporeans: (1) Traditional Family Oriented, (2) New Age Family Oriented, (3) Entrepreneurs, (4) Aspirers, (5) Materialists, (6) Pragmatists, and (7) Independents. Finally, to examine whether the identified value-based clusters could also be differentiated in terms of key demographic variables, a discriminant analysis was conducted. The results showed that the seven clusters had distinctive patterns along demographic variables. The examination of the aspirations and life satisfaction of the clusters showed that significant differences did exist among themselves. These differences in aspirations and life satisfaction were consistent with the traits and attitudes of the respective clusters and provided ample support to the grouping of the clusters.     

Optimism and auditor liability

There is strong evidence that individuals are optimistic in the sense that they underrate the probability of a negative event occurring. This paper provides a positive theoretical analysis of how auditor optimism affects their incentives to take care under two liability rules: strict liability and a negligence rule. Under strict liability, auditors are held liable when they cause damages to investors. Under a negligence rule, auditors are held liable when they cause damages and in addition, act negligently, that is, fail to meet the standard of due care specified in legal and professional rules. I find the following results. (1) If due care is sufficiently close to the efficient level, a negligence rule distorts auditors’ incentives less than strict liability. Under strict liability, optimism makes the auditor overestimate the chances of finding material mistakes and thus induces suboptimal care. (2) If due care is too strict, the auditor will not exert due care but the same level of suboptimal care under either liability rule. (3) With increasing optimism and in the absence of punitive damages, strict liability becomes less preferable to a precise negligence rule. This statement also holds for vaguely defined standards of due care if due care is sufficiently strict or if auditor optimism is sufficiently high. (4) Punitive damages counteract suboptimal incentives generated by auditor optimism, especially under strict liability.     

Stable mixture GARCH models

A new model class for univariate asset returns is proposed which involves the use of mixtures of stable Paretian distributions, and readily lends itself to use in a multivariate context for portfolio selection. The model nests numerous ones currently in use, and is shown to outperform all its special cases. In particular, an extensive out-of-sample risk forecasting exercise for seven major FX and equity indices confirms the superiority of the general model compared to its special cases and other competitors. Estimation issues related to problems associated with mixture models are discussed, and a new, general, method is proposed to successfully circumvent these. The model is straightforwardly extended to the multivariate setting by using an independent component analysis framework. The tractability of the relevant characteristic function then facilitates portfolio optimization using expected shortfall as the downside risk measure.     

Youth leisure careers during post‐communist transitions in the South Caucasus

This paper reports findings from interview surveys with 1215 respondents, split between the capital cities (Yerevan, Baku and Tbilisi) and one non‐capital region (Kotayk, Aran‐Mugan and Shida Kartli) in each of the three South Caucasus countries – Armenia, Azerbaijan and Georgia. The respondents, who were drawn from households in larger representative household social surveys, were all born between 1970 and 1976 and were aged 31–37 at the time of the fieldwork in 2007. Their life stage transitions from childhood to adulthood had roughly coincided with their countries’ transitions from communism to post‐communism. Data was collected on the samples’ participation in selected leisure activities from age 16 to 30. Similar data was collected on the samples’ careers in education, the labour market, housing and family relationships. This information enables us to identify typical leisure careers and how their development was affected by events in other life domains, all in the context of the macro‐changes that were in process in each of the research locations. The evidence enables both personal leisure careers and aggregate leisure trends in different socio‐demographic groups to be identified This shows that changes in leisure behaviour between age 16 and 30 were neither widening nor narrowing the differences between the leisure of males and females, or those who married and became parents on the one hand, then, on the other, those who were still single and childless at age 30. In contrast, differences by place, and by social class, grew progressively wider, thus raising the social costs of geographical and social mobility. Changes in leisure behaviour between age 16 and 30 were separating young adults into those who participated in little, if any, structured out‐of‐home leisure, whose main leisure spending, if any, was on alcohol and tobacco (typically consumed in homes and neighbourhoods), and those whose leisure was characterised by relatively high and sustained participation in sport, consumption of high culture, and going out to bars, cafes, cinema, discos, etc.     

Heinrich von Storch's innovative contributions to economics

Heinrich von Storch was a classical economist of the late eighteenth and early nineteenth century; he was of German descent and of Russian nationality; his main work was written in French. This paper tries to present the essence of Storch's innovative ideas and contrasts them with contemporary British and French economic thinking on value, land rent, foreign trade, money and currency, “inner goods,” and development. It is argued that Storch was an economist of moderate impact on literature but of high professional relevance.     

50 Jahre Baumol‘sche Kostenkrankheit

The year 2017 marks the 50th anniversary of William J. Baumol’s “Cost Disease”, which posits that services with low productivity growth become more expensive relative to goods while aggregate productivity growth slows down in the process of tertiarisation. The authors present the basic structure of Baumol’s model and discuss several attempts to refute the concept or to cope with its consequences. One of them is the important observation by Nicholas Oulton that business services — unlike personal services — can contribute to higher aggregate productivity growth. A major precondition is that the productivity growth of business services is positive. However, an empirical test shows that this is not the case in Germany and other major advanced economies. Some economic policy conclusions are drawn.
