This paper analyzes the initial public offering (IPO) underpricing phenomenon in Portugal. We show that the ‘hot issue’ market
of 1987, coinciding with a speculative bubble in the stock market, is well explained by investor sentiment theories and that
the issuing firms seized a ‘window of opportunity’ provided by excessive demand to offer and list their shares. In IPOs prior
to the 1987 crash, underpricing is very high while there is a strong reversion to fundamentals in the long run. In the period
1988–2004, we find lower IPO underpricing and overall no evidence of long-run underperformance of IPO firms. Bookbuilding
IPOs are more underpriced than other price setting systems IPOs, and firms with seasoned public offerings show abnormal returns
in the long run.

We test the existence of an endogenous relationship between well-being and employment for US individuals. To that end, we
use a simultaneous equation generalized Probit model applied to four recent waves of the National Health Interview Survey
(1997–2000). Our results do not enable us to accept the hypothesis that there is a significant effect from employment status
to subjective well-being. In contrast, we provide evidence that suggest that well-being is positively correlated to the probability
of having a job.

This paper provides a tractable, parsimonious model for assessing basis risk in longevity and its effect on the hedging strategies of Pension Funds and annuity providers. Basis risk is captured by a single parameter, that measures the co-movement between the portfolio and the reference population’s longevity. The paper sets out the static, full and customized swap-hedge for an annuity, and compares it with a dynamic, partial, and index-based hedge. We calibrate our model to the UK and Scottish populations. The effectiveness of static versus dynamic strategies depends on the rebalancing frequency of the second, on the relative costs, and on basis risk, which does not affect fully-customized, static hedges. We show that appropriately calibrated dynamic hedging strategies can still be reasonably effective, even at low rebalancing frequencies. 相似文献

Before December 1999, the capital gains of shareholders who sold their shares into Australian takeovers have been taxable irrespective of payment method. Subsequently, shareholders can elect to rollover capital gains in equity takeovers. We examine the effect of this change on the association between target shareholder capital gains and bidder and target firm shareholder wealth. The results indicate that prior to the regulatory change, cash consideration results in higher target shareholder returns for non‐taxation reasons. After the introduction of capital gains tax rollover relief, we find that target and acquiring firm shareholders earn lower returns when cash consideration is offered to shareholders with greater capital gains. 相似文献

In this paper, we study the optimal tax policy in a differential oligopoly game where the competing firms share the access to a productive renewable resource. We show that, in a Feedback Nash Equilibrium of the game, a linear Markov tax, imposed on the output, and specified as an affine function of the available resource stock, leads the competing firms to produce the socially optimal quantities over time, thus overcoming the dynamic interplay between the tragedy of the commons and the firms’ market power. The optimal tax turns out to be independent from the resource stock in a monopoly, and it cannot be defined in a duopoly. 相似文献

Low socio economic stratum (SES) consumers face constrains that engender creativity as they try to solve consumption problems using the scant products and services available by repurposing such products. This research investigates mechanisms by which hope and integral emotions interact with SES to influence consumer creativity. Experiments with low and high SES participants in an emerging economy show that when hope is enhanced, positive integral emotions are directed to creativity by all consumers, but when hope is diminished, positive integral emotions are not consistently directed to creativity. SES exerts a moderating role when hope is diminished, and only high SES participants are able to cope with the absence of hope by redirecting dominance feelings to creativity. Results suggest that increasing hope among low SES consumers can enhance their creativity, and that hope can be enhanced through actions undertaken by companies and public organizations. 相似文献

In this paper we collect some old and new qualitative-structural properties on the input and output matrices involved in the classical von Neumann model, properties relevant, from the formal and/or economic point of view, in the study of the equilibria of the said model. It is established the hierarchy, i.e. the relations of inclusion, partial overlapping and disjunction, among these properties, which permits to amend some current slips in the analysis of the von Neumann model (one due to von Neumann himself). The results obtained can be fitted to other production and exchange multisectorial models. 相似文献

To reverse the negative environmental impacts of agriculture, a land evaluation decision support system (DSS) known as MicroLEIS-DSS was used to design the most sustainable land use and management practices for selected Mediterranean benchmark sites in Sevilla Province, Southern Spain. This DSS is based on the multifunctional evaluation of soil quality, using input data collected in standard soil surveys, and with particular reference to the peculiarities of the Mediterranean region. Specific agro-ecological strategies to prevent soil degradation in the benchmark sites were designed within two major topics: (i) strategies related to land use planning at a regional level: segregation of agricultural lands, restoration of marginal areas, diversification of crop rotation, and identification of vulnerability areas; and (ii) those related to land management planning at a farm level: organic matter restoration, formulation of tillage practices and workability timing, optimum machinery use, and input rationalization. The predicted results of applying the 12 agro-ecological land evaluation model constituents of MicroLEIS DSS are presented and discussed for each application site. The main conclusion of this paper is that using soil type information in decision-making is at the heart for sustainable use and management of agricultural land. This agro-ecological approach can be especially useful when formulating soil-specific agricultural practices to reverse environmental degradation, based on the spatial variability of soils and related resources. 相似文献
