Using a sample of up to 2,503 initial public offerings (IPOs) in 32 countries from 2011–2017, we predict and find that higher levels of country-level accounting enforcement are associated with lower levels of IPO underpricing. IPOs in countries with a relatively low accounting enforcement score (second quintile) exhibit a mean underpricing of 19%, whereas the mean underpricing amounts to just 9% in countries with a relatively high score (fourth quintile). The results remain qualitatively the same when we employ a multi-level model or a difference-in-difference design. In countries that substantially strengthened their accounting enforcement in the 2003–2009 period, the level of IPO underpricing decreased significantly. We show that accounting enforcement matters for the cost of going public. 相似文献

Special purpose acquisition companies (SPACs) are created to raise capital and then find non-listed operating companies with which to merge. While most of the extant research has focused on SPAC initial public offerings, we study what happens when SPACs announce business combinations. Our analysis of 236 ‘deSPACs’ completed between January 2012 and June 2021 in the United States documents an average short-term announcement return of +7.4% and a 1-year abnormal return of −14.1% (−18.0% over 2 years) for public investors beginning from the merger announcement. Short-term returns decrease with longer times from initial public offering until announcement. 相似文献

Political targets for implementing the German “energy turnaround” aiming at the ambitious extension of renewable energies to generate electricity. However, a majority of the renewable supply is provided by intermittent sources, e.g. wind and solar power. For balancing the increasing supply fluctuations additional storage options are claimed beside of an enforced grid infrastructure and a more flexible demand side. Despite of the political guidelines the economics of additional flexibility measures has to be considered. For this paper we analyse the costs of large scale stationary battery storages to be operated in wholesale markets and transmission grid level. By deriving a key figure based on a life-cycle cost approach, we are able to evaluate the additional costs of electricity of selected battery technologies (lead-acid, lithium ion, sodium sulphur, redox-flow). Moreover, current and valid parameters of the cost analysis are received by scientific and industrial stakeholders of battery systems via online survey and face-to-face interviews. According to the stakeholder estimation a nationwide operation of stationary battery storages will be established at wholesale and transmission grid level until the year 2030. The life-cycle cost analysis, which also includes estimated future cost reductions, shows that lead-acid batteries remain the cost-efficient technology, assuming about 100 storage cycles p.a. In addition, a sensitivity analysis reveals the impact of increasing annual storage cycles as well as the achievable cost reduction by economies-of-scales of the power unit of the storage system. 相似文献

In this paper, we present a new stylized fact for options whose underlying asset is a stock index. Extracting implied volatility time series from call and put options on the Deutscher Aktien index (DAX) and financial times stock exchange index (FTSE), we show that the persistence of these volatilities depends on the moneyness of the options used for its computation. Using a functional autoregressive model, we show that this effect is statistically significant. Surprisingly, we show that the diffusion-based stochastic volatility models are not consistent with this stylized fact. Finally, we argue that adding jumps to a diffusion-based volatility model help recovering this volatility pattern. This suggests that the persistence of implied volatilities can be related to the tails of the underlying volatility process: this corroborates the intuition that the liquidity of the options across moneynesses introduces an additional risk factor to the one usually considered. 相似文献

Migration dynamics and local biodiversity are interrelated in a way that is likely to affect patterns of regional specialisation. We assess this relationship with a New Economic Geography model that has been extended with biodiversity. Biodiversity is heterogeneous, and responds to habitat availability. The results indicate that a symmetric pattern of regional specialisation is more likely, and that additional equilibria may emerge as the marginal utility of biodiversity increases. In the policy analysis we focus on the case where the overall social optimum is symmetric and show that it can be supported as a non-cooperative Nash equilibrium. However, multiple Nash equilibria may exist. 相似文献

This paper reports upon the testing of the comparative performance of eight epidemic based diffusion models on data describing the diffusion of camcorders and CD players in the UK and cars in West Germany. Standard epidemic models of new product diffusion are modified to allow for the influence of economic factors and compared to a recent model proposed by Karshenas and Stoneman. The performance of the Karshenas and Stoneman model is good, but so is that of an alternative model in the Marketing literature proposed by Easingwood, Mahajan and Muller. 相似文献

Richard H. Thaler was awarded this year’s Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel “for his contributions to behavioural economics”. He studied systematic departures of human behaviour from the standard “homo oeconomicus” assumption. His famous work on boundedly rational behaviour considers both cognitive limitations and limited self-control. The cognitive limitations he studied are in particular the endowment effect, i.e. the observation that individuals assign a higher value to an object if they possess it, and mental accounting, a collection of theories regarding how individuals think about money. Furthermore, he provided path-breaking evidence on the nature of social preferences, which laid the groundwork for the development of several widely used economic theories incorporating altruism, fairness and reciprocity. 相似文献
