This article analyses 336 German venture capital transactions from 1990 to 2005 and seeks to determine why selected financial securities differ across deals. We find that a broad array of financial instruments is used, covering straight equity, mezzanine and debt‐like securities. Based on the chosen financial securities’ upside potential and downside protection characteristics, we provide an explanation for the differing use of these securities. Our results show that investors’ deal experience, adverse selection risks and economic prospects in the public equity market influence the selection of financial securities.  相似文献

This paper reports the findings of a longitudinal comparative case study of three National Health Service (NHS) hospital Trusts in England, investigating the perceptions of clinical, managerial and accounting professionals towards changing cost accounting and performance measurement practices. It incorporates both qualitative and quantitative data analysis, and is based on a contextualist understanding of change management, utilising the content‐process‐context approach (Pettigrew and Lapsley, 1994) to investigate the influence of receptive versus non‐receptive contexts on change. The analysis reveals limited success in improving performance measurement practices (the content of change) in Trusts. Nevertheless the specific context within which change was operationalised was found to be very important, with central mangers playing a key role in influencing change. The process of change indicated slow shifts in clinical‐accountant‐managerial relations, partly driven by changes in financial flows within the organisations.  相似文献

This paper explores a wide range of corporate restructurings, all available deals from wire services, in the banking and insurance sectors that led to bancassurance ventures. An event study methodology is employed to calculate excess returns on and around the deals’ announcement date. Using both univariate and multivariate analysis the paper finds bank driven mergers, deal's size and regional categorization all triggering positive and significant market reactions. Unlike the univariate framework, multivariate analysis shows that geographic focus and language are not significant factors. The results also indicate that markets are indifferent with respect to bank withdrawals from the bank‐insurance operations. Finally, Canadian, U.S. and European bank‐insurance deals produce positive results, while Australasian bidders offer statistically insignificant equity returns.  相似文献

We explore determinants of flood insurance demand in the coastal zone using micro‐data for nine Southeastern counties. Overall estimates indicate price inelastic demand, though subsidized policyholders have greater coverage and are more price sensitive. Mortgage borrowers exhibit no greater coverage; only 12 percent in 100‐year flood zone indicate flood insurance was required by their lender. Flood insurance demand is increasing in the levels of flood and erosion risk. We find a positive correlation between household income and coverage, but the effect is not monotonic. Community‐level erosion hazard mitigation projects influence flood insurance coverage, with beach replenishment acting as a complement.  相似文献

This article presents a case study of a portfolio of individual long‐term insurance contracts sold by a Spanish mutual company. We describe the risk levels, the rating structure, and the implied cross‐subsidies on a portfolio of policies providing health, life, and long‐term care insurance. We show evidence of reclassification risk through the history of disability spells. We also analyze the lapse behavior and seek to provide a rationale for the portfolio’s dynamics. We discuss the lack of commitment from the policyholders (lapses) and from the mutual company (which took a run‐off decision). Finally, we draw conclusions regarding the design of such contracts.  相似文献

This research analyzes the impact of control by dominant institutional owners (banking institutions and investment funds) on firm value. The analysis considers the level of voting rights in the hands of the dominant institutional owner and other large shareholders. The results reveal a different effect on value depending on whether the dominant institutional investor is a banking institution or an investment fund. Moreover, the results show that the presence of other large shareholders affects firm value when a dominant institutional owner controls the firm.  相似文献

We investigate optimal consumption policies in the liquidity risk model introduced by Pham and Tankov (Math. Finance 18:613–627, 2008). Our main result is to derive smoothness C 1 results for the value functions of the portfolio/consumption choice problem. As an important consequence, we can prove the existence of the optimal control (portfolio/consumption strategy) which we characterize both in feedback form in terms of the derivatives of the value functions and as the solution of a second-order ODE. Finally, numerical illustrations of the behavior of optimal consumption strategies between two trading dates are given.  相似文献

Using data on a five-minute interval basis, this article analyses the effects of intraday seasonality on volatility transmission between the spot and futures markets of the CAC40, DAX30 and FTSE100. Remarkable differences in the impulse response analysis and in the dynamic and directional measurement of volatility spillovers are encountered depending on whether the intraday periodic component is considered. Thus, the convenience of removing intraday seasonality seems to be critical to reduce the risk of spurious causality when employing high-frequency data in volatility transmission. Moreover, the impact of market microstructure noise seems negligible when using an optimal frequency of observations.  相似文献

Money exchange is one of the most common day‐to‐day activities performed by humans in the daily market. This paper presents an approach to money tracking through a blockchain. The proposed approach consists of three main components: serial number localization, serial number recognition, and a blockchain to store all transactions and ownership transfers. The approach was tested with a total of 110 banknotes of different currency types and achieved an average accuracy of 91.17%. We conducted a user study in real‐time with 21 users, and the mean accuracy across all users was 86.42%. Each user gave us feedback on the proposed approach, and most of them welcomed the idea.  相似文献

Our main objective is to study the effect of institutional directors on firm performance, distinguishing directors according to whether they maintain business relationships (pressure‐sensitive) or not (pressure‐resistant). Our results show that in weak regulatory and low investor protection environments, institutional directors have a negative impact on corporate performance. Our evidence shows that this negative effect is mainly driven by the role of pressure‐resistant directors and not for those directors representing mainly banks and other financial institutions with a long‐term investment horizon. These findings have implications for numerous parties, such as institutional investors, regulators, potential new board members and other corporate governance reform proponents, who frequently examine board characteristics to assess the effectiveness of boards in value‐creation policies.  相似文献
