The Effect of Acculturation on Reparative Behavior in Shame and Guilt Cultures

As the number of immigration and their later generations grow in the workforce of more developed Western countries, understanding the processes and consequences of acculturation has gained a new level of importance. An old and re-emerging issue is the morality and reparative behavior in Western versus Eastern cultures, as well as its antecedents and consequences. We examined the effects of acculturation on the perception of psychological proximity, the intensity of moral emotions of shame and guilt, and the degree of compensation to victims of one＇s wrongdoing. Our sample was comprised of a collectivistic group from a shame culture, China, and an acculturated group of Chinese living in a much less collectivistic society of a guilt culture, Canada. Our results indicated that participants＇ perception of psychological proximity to other people and the level of compensation offered to the victims of transgression were significantly different among the two samples. Furthermore, shame and guilt mediated the relationship between perceived psychological proximity and the decision to compensate differently.     

A note on the gender reservation wage gap in developing countries

This is the first paper to document the existence of a gender reservation wage gap in developing countries. We find a 22.6% gender reservation wage gap, a gap that is much larger than current estimates for developed countries. Assets play the largest role in closing this gap, whereas adult height widens the gap among the poor.     

The cost-effectiveness of biologic versus non-biologic treatments and the health-related quality of life among a sample of patients with inflammatory bowel disease in a tertiary care center in Saudi Arabia

Abstract

Aims

This study’s objectives were to examine and compare the cost-effectiveness of biologic and non-biologic therapies in the improvement of the health-related quality of life (HRQoL) of patients with inflammatory bowel disease (IBD) in Saudi Arabia.     

A study on the mean past lifetime of the components of (n − k + 1)-out-of-n system at the system level

In the present paper, we consider a (n − k + 1)-out-of-n system with identical components where it is assumed that the lifetimes of the components are independent and have a common distribution function F. We assume that the system fails at time t or sometime before t, t > 0. Under these conditions, we are interested in the study of the mean time elapsed since the failure of the components. We call this as the mean past lifetime (MPL) of the components at the system level. Several properties of the MPL are studied. It is proved that the relation between the proposed MPL and the underlying distribution is one-to-one. We have shown that when the components of the system have decreasing reversed hazard then the MPL of the system is increasing with respect to time. Some examples are also provided.     

A comparison principle between rough and non-rough Heston models—with applications to the volatility surface

We present a number of related comparison results, which allow one to compare moment explosion times, moment generating functions and critical moments between rough and non-rough Heston models of stochastic volatility. All results are based on a comparison principle for certain non-linear Volterra integral equations. Our upper bound for the moment explosion time is different from the bound introduced by Gerhold, Gerstenecker and Pinter [Moment explosions in the rough Heston model. Decisions in Economics and Finance, 2019, 42, 575–608] and tighter for typical parameter values. The results can be directly transferred to a comparison principle for the asymptotic slope of implied variance between rough and non-rough Heston models. This principle shows that the ratio of implied variance slopes in the rough versus non-rough Heston model increases at least with power-law behavior for small maturities.     

Modeling the Caspian Sea Negotiations

The objective of this study is to identify techniques for predicting the outcome of a negotiation and then apply them to the current negotiations over the legal status of the Caspian Sea, which has been in dispute since the collapse of the Soviet Union. The five coastal states—Azerbaijan, Iran, Kazakhstan, Russia, and Turkmenistan—entered negotiations in 1993, but have not yet agreed on who owns the waters or the oil and natural gas beneath them. We identify the five well-defined options for resolving the dispute and then discuss the states’ preferences regarding these options. We apply some well-known social choice rules to find the “socially optimal” resolution. Then we review several versions of Fallback Bargaining, which aims to minimize the maximum dissatisfaction of the bargainers, and apply them to the dispute. Finally, we represent the dispute in financial terms and apply several well-known bankruptcy procedures, which are fair division methods for settling monetary claims. We end with some suggestions on how the value of the Caspian seabed resources could be allocated among the five Caspian states.     

Special focus: The Bangladesh sorghum experiment

In 1978, an experiment was undertaken in Bangladesh to test the possibility of targeting part of the country's public food system toward the poorer and more malnourished population groups through the introduction of a lower-status, but nutritionally valuable food. Sorghum, as a representative inexpensive coarse grain, was selected and introduced into a set of ration shops in both urban and rural areas. Given the low, or negative, income elasticity of demand for sorghum among the middle class, offtakes in the urban test were low. However, in the rural areas, offtakes were substantial, particularly among the lower-income groups, reaching almost 70% in one of the two districts studied. Although this would suggest that the programme has considerable potential in affecting malnutrition and, to a lesser extent, the distribution of income, other information collected on the rural ration system as a whole indicates that, unless the larger system is reoriented, this potential has little chance of being realized.     

To Sue or Not to Sue: An Experimental Study of Factors Affecting Hong Kong Liquidators Audit Litigation Decisions

We report an experiment examining the effect of three factors on professional Hong Kong liquidators' decisions to bring legal action in negligence against auditors. Factors were (a) the strength (merit) of the supporting evidence (arguable vs. overwhelming), (b) the type of alleged audit failure (failure to report financial statement errors vs. management fraud) and (c) audit firm type (Big 6 vs. non-Big 6). We find evidence that liquidators' litigation decisions are influenced by case merit. We also find that liquidators were marginally more likely to institute legal action against a Big 6 than against a non-Big 6 auditor. However, we find no evidence that the type of alleged audit failure influences litigation decisions.     

Deregulation, consolidation and banks efficiency in Singapore: Evidence from event study window approach and Tobit analysis

A three-year window analysis together with the Data Envelopment Analysis (DEA) approach is employed to investigate the effects of mergers and acquisitions on the Singapore banking groups’ efficiency. The results suggest that the merger has resulted in a higher Singapore banking groups’ mean overall efficiency. We do not find evidence of more efficient acquirers compared to the targets and that the acquiring banks’ mean overall efficiency tends to improve from the merger with a more efficient bank. The Tobit regression results suggest that bank profitability has positive impact on bank efficiency, whereas poor loan quality has negative influence on bank performance.
