Income and reproductive motivation

Abstract It is often assumed that family size and income would be positively related if unwanted births among the less advantaged were prevented. But this assumption rests on a prior expectation that family-size preferences bear a direct relation to income in modern societies. Data on such reproductive preferences in relation to economic status from 13 studies in the United States dating between 1936 and 1966 do not support the notion of a positive association between reproductive preferences and income. Only when Catholics are considered is there even a U-shaped relation between family-size desires and income. These results cast doubt on the notion that the economic theory of demand for consumer durables is relevant to reproductive motivation. Rather, the data lend credence to the idea that significant non-economic influences associated with prosperity depress family-size desires among the well-to-do. Only if these influences are specifically weakened by a counter-force (such as Catholicism) do wealthier people show a preference for somewhat larger families. In no case, however, are the Catholic/non-Catholic differences in reproductive preference large. Moreover, no economic group, even among non-Catholics, prefers very small families.     

Management of accounting: The case for an active role

Regulations imposed upon both the external and internal accounting reports of enterprises may evoke a variety of responses from managers ranging from the active to the passive. This paper explores the active, participatory role which managers may choose to adopt in influencing the direction of accounting regulations. Reference is made to a large number of cases arising in Europe and elsewhere which illustrate how managers have provided benefits to their businesses by actively lobbying for constructive changes in the accounting environment.     

Risk Assessment Based on Financial Data: Market Response to Airline Accidents

The risk of catastrophic failures, for example in the aviation and aerospace industries, can be approached from different angles (e.g., statistics when they exist, or a detailed probabilistic analysis of the system). Each new accident carries information that has already been included in the experience base or constitutes new evidence that can be used to update a previous assessment of the risk. In this paper, we take a different approach and consider the risk and the updating from the investor's point of view. Based on the market response to past airplane accidents, we examine which ones have created a surprise response and which ones are considered part of the risk of the airline business as previously assessed. To do so, we quantify the magnitude and the timing of the observed market response to catastrophic accidents, and we compare it to an estimate of the response that would be expected based on the true actual cost of the accident including direct and indirect costs (full-cost information response). First, we develop a method based on stock market data to measure the actual market response to an accident and we construct an estimate of the full-cost information response to such an event. We then compare the two figures for the immediate and the long-term response of the market for the affected firm, as well as for the whole industry group to which the firm belongs. As an illustration, we analyze a sample of ten fatal accidents experienced by major US domestic airlines during the last seven years. In four cases, we observed an abnormal market response. In these instances, it seems that the shareholders may have updated their estimates of the probability of a future accident in the affected airlines or more generally of the firm's future business prospects. This market reaction is not always easy to explain much less to anticipate, a fact which management should bear in mind when planning a firm's response to such an event.

Predicting Problem Gambling in Australian Adults Using a Multifaceted Model of Impulsivity

Impulsivity is a factor that has been linked strongly to problem gambling; however, conceptualization problems have impeded research in this area. Research suggests that there may be as many as five impulsivity subtypes and that some but not all of these subtypes are involved in problem gambling. This cross-sectional and correlational study used the multifaceted UPPS-P Impulsive Behaviour Scale as a predictor of problem gambling in a community (N = 200) sample of Australian adult gamblers. Of the five impulsivity subtypes, negative urgency, positive urgency and sensation seeking were found to be positively related to problem gambling, while lack of premeditation and lack of perseverance were unrelated. Multiple regression analyses revealed that positive urgency and negative urgency were the only significant predictors of problem gambling, suggesting that individuals who have the tendency to act rashly when in a positive or negative mood are more likely to display problem gambling behaviour. The results provide further evidence of the significant role of strong emotions in problem gambling. Further, it appears that problem gambling can be motivated both by the impulsive desire to avoid negative mood states and by the impulsive desire to maintain and enhance positive mood states.     

Navigating the First Year of College: Siblings,Parents, and First-Generation Students’ Experiences

Although college education is a key to upward mobility, students from socioeconomically disadvantaged backgrounds are less likely to enter and complete college than their more advantaged peers. Prior literature has illuminated how cultural capital contributes to these disparities. An alternative conceptualization of cultural capital, however, suggests that it can also play a role in social mobility. In this study, we build on and extend the literature on cultural mobility by proposing that exposure to education can benefit not only individuals but also families. We examine the influence of older siblings who attended college on the experiences of younger college-going siblings in families where neither parent has completed college (i.e., first-generation families). We find that students rarely rely on their older siblings as sources of information and advice, except in a few instances where older siblings attended the same institution. However, both the topics and nature of conversations between parents and students differ between families with and without older college-educated siblings. The primary benefit of having college-educated siblings is thus related to students’ engagement with and support received from parents. These findings have important implications for cultural capital research and understanding experiences of first-generation college students.
