Young workers in the 1990s can expect greater economic insecurity, as well as lower average earnings, compared to older workers, or compared to the youth of previous decades. The cost of greater insecurity depends upon an individual's probability of unemployment, marginal utility of income gains/losses and the extent to which individuals can smooth consumption over time by borrowing and drawing down assets. Since unemployment insurance cutbacks and higher unemployment have increased the risk exposure of youth, changes in the expected value of their income may understate utility losses as measured by the change in certainty equivalent income.
This paper uses a behavioural microsimulation model to compare the impacts of 1971 and 1994 unemployment insurance legislation and unemployment rates in Canada. It calculates both the expected value of income changes and, using a Stone-Geary utility function, the change in inequality of well-being (as measured by certainty equivalent income) for youth and for prime age workers. Both calculations reveal that youth were disproportionately affected by Canada's changing labour market environment. Very few youth have enough assets to finance consumption during spells of unemployment.  相似文献

Summary. Differentiability is a convenient property of von Neumann-Morgenstern utility functions which is almost always imposed but has not been translated into behavioral terms. In applications, expected utility is usually maximized subject to a constraint, and the maximization is carried out by differentiating the utility function. This paper presents two sets of necessary and sufficient conditions for a risk averse von Neumann-Morgenstern utility function to be differentiable. The first of them is formulated in terms of the equivalent risk premia of small gambles. It says, in brief, that the equivalent risk premium is of a smaller order of magnitude than the risk itself, as measured by the expectation of the absolute value of the risk. The second set of necessary and sufficient conditions is formulated in terms of the probability premium of small lotteries. It says, essentially, that the probability premium for small binary lotteries goes to zero as the size of the lottery goes to zero. Received: May 11, 1997; revised version: May 14, 1998  相似文献

Using Swedish equity option data, this study investigates how well the actual exercise behavior of American put options corresponds to the early exercise rules. The optimal exercise strategy is established in two ways. First, the critical exercise price, above which a put option should be exercised early, is computed and compared to the actual exercise price. Second, the exercise value of the option is compared to its market bid price. The results show that most early exercise decisions conform to rational exercise behavior, even though a large number of failures to exercise are found. Most of the faulty exercises can also be discarded after a sensitivity analysis, although several failures to exercise are considered irrational, even after taking transaction costs into account. © 2000 John Wiley & Sons, Inc.

We investigate the funding modes of German banks and the implications for lending and profitability during 1992–2002. We find that at many banks, deposits from customers decrease in relative terms while interbank liabilities increase as a source of funding. We cannot detect a negative impact of the relative decline in deposits on lending. The decreasing ability of banks to collect deposits and the substitution of deposits by interbank liabilities unfavorably affects the net interest result of banks that exhibit a deposit deficit, especially savings banks. Our findings indicate a structural lengthening of the intermediation chain, which has broader implications for the functioning and stability of the financial system.  相似文献

This article describes the preliminary studies of the effect of advertising and promotion on purchases. The British single-source database Adlab has been the basis for this study of advertising and promotion effectiveness. The ST AS measure and logit modelling have been used to estimate the effect of advertising. The results from the two measures have been compared to determine the extent to which the two measures give occasion for the same conclusions. To indicate the accuracy of the two measures, their respective levels of significance have been studied. Two logit models have been estimated; one only includes the effect of TV exposure, while the other also includes the effect of promotions. The results from the two logit models are compared to determine which model gives the most accurate estimate of the effect of advertising. When comparing the results from the STAS measure with the parameter estimates from the second logit model, it is found that these two different measures largely lead to similar conclusions. Suggestions for further research and developments of the models are given.  相似文献

Research on entrepreneurship has flourished in recent years and is evolving rapidly. This article explores the history of entrepreneurship research, how the research domain has evolved, and its current status as an academic field. The need to concretize these issues stems partly from a general interest in defining the current research domain and partly from the more specific tasks confronting the prize committee of the Global Award for Entrepreneurship Research. Entrepreneurship has developed in many sub-fields within several disciplines—primarily economics, management/business administration, sociology, psychology, economic and cultural anthropology, business history, strategy, marketing, finance, and geography—representing a variety of research traditions, perspectives, and methods. We present an analytical framework that organizes our thinking about the domain of entrepreneurship research by specifying elements, levels of analysis, and the process/context. An overview is provided of where the field stands today and how it is positioned relative to the existing disciplines and new research fields upon which it draws. Areas needed for future progress are highlighted, particularly the need for a rigorous dynamic theory of entrepreneurship that relates entrepreneurial activity to economic growth and human welfare. Moreover, applied work based on more careful design as well as on theoretical models yielding more credible and robust estimates seems also highly warranted.  相似文献

This paper presents an integrative review of the literature on cause-related marketing (CRM) persuasion research (i.e. studies of how CRM influences evaluations of the partner brand). The aim of the study was to review CRM persuasion research and to integrate the findings into a theoretical framework that could direct future research efforts in the area. Drawing on Bergkvist and Taylor's model of Leveraged Marketing Communications (LMC), a dual-path model of CRM persuasion effects was developed. According to the model, CRM affects brand evaluations along two paths: the indirect transfer path which is mediated by attribution of motives and the direct transfer path in which attitude towards the cause is transferred to the brand. The model incorporates results from extant research and provides guidance for future studies.  相似文献

A common managerial belief indicates that brand loyalty declines over the years, with consumers becoming more heterogeneous in their choices. The earlier research investigating the phenomenon of brand loyalty decline is, however, inconclusive and does not offer an answer to the reasons behind brand loyalty evolution. In this study, we investigate brand loyalty evolution and explore the impact that a number of category characteristics have on driving brand loyalty evolution. We use Danish panel data across 54 categories over a period of 6 years (2006–2011). Our findings show that at the aggregate level, brand loyalty declines, but this evolution is category-specific, with only a small number of categories showing a significant decline. We further demonstrate that an increase in category penetration results in a negative impact on brand loyalty evolution, whereas an increase in the share of private label brands has a positive impact. We discuss the implications for theory and practice.

We investigate whether and how corporate leverage depends on the structure of corporate assets. Based on a large panel dataset of US firms from 1990 to 2010, we show that property, plant and equipment are important drivers of the collateral channel, while inventories and receivables are less important. The collateral channel is more pronounced for firms that have to rely on banks and trade creditors to raise debt finance, but it has become weaker for these firms after the start of the financial crisis. Our study provides new evidence on the cross-sectional and time-varying importance of the collateral channel for corporate leverage.  相似文献

Investment liberalizing countries are often concerned that cross-border mergers and acquisitions, in contrast to greenfield investments, might have an adverse effect on domestic firms and consumers. However, given that domestic assets are sufficiently scarce, we identify a preemption effect and an asset complementarity effect, which imply that the acquisition price is substantially higher than the domestic seller's profits. Moreover, we show that for the acquisition to take place, the MNE must be sufficiently efficient when using the domestic assets, otherwise rivals will expand their business, thereby making the acquisition unprofitable. Consequently, restricting cross-border M&As may also hurt consumers.  相似文献
