The Determinants of Venture Capital in Europe—Evidence Across Countries

Abstract This article analyses the determinants of European venture capital activity. The main novelty of our work is in accounting for the idiosyncrasies of the European venture capital market. In particular, we investigate whether the size of the merger and acquisition market (M&A) is important in explaining venture capital. Moreover, our work is the first that analyses the impact of the degree of information asymmetry at the macro level, the direct impact of the level of entrepreneurial activity and the impact of the unemployment rate on venture capital activity. We use aggregate data from 23 European countries for the period 1998–2003 to estimate panel data models with fixed and random effects. Our results reveal that the size of the M&A market and the market-to-book ratio have a positive impact on venture capital activity whereas the unemployment rate influences the venture capital market negatively. These results highlight the importance of the exit environment and of the degree of asymmetric information for the venture capital market

The exit decision in the European venture capital market

This article analyses the exit decision in the European venture capital market, studying when to exit and how it interacts with the exit form. Using a competing risks model we study the impact on the exit decision of the characteristics of venture capital investors, of their investments and of contracting variables. Our results reveals that the hazard functions are non-monotonic for all exit forms and suggest that, in Europe, Initial Public Offering candidates take longer to be selected than trade sales. Moreover our results show that, in Europe, venture capitalists associated with financial institutions have quicker exits (stronger for trade sales), and highlight the importance of contracting variables on the exit decision. An unexpected result is that the presence on the board of directors leads to longer investment durations

Contribuição dos sistemas agroflorestais (Saf’s) para a multifuncionalidade da agricultura familiar na área de atuação do Ipêterras no Território de Identidade de Irecê

En la tesis que presentarse, proponerse analizar-por la contribución de los Sistemas agroforestales – SAF’s-, para la multifuncionalidad de la agricultura campesina en 5 (cinco) municipios del territorio de identidad de Irecê-Ba. Haga vista que los SAF’S viene siendo mucho investigado como uno modelo agroecológico; como modo de vida y forma productiva, por contener los principios de la preservación ambiental; seguridad nutricional y alimentar; preservación y rescate sociocultural; generación de abono y trabajo responsable y equidad social.

Which criteria matter most in the evaluation of venture capital investments?

Structured Abstract Purpose - This study identifies the importance assigned to the various criteria used by the Portuguese Venture Capitalists (VCs) to evaluate and select early stage venture capital projects. Design/methodology/approach - The data was collected through a questionnaire answered by 20 Portuguese VCs. We use descriptive statistics techniques and non-parametric tests to identify the most valued criteria and test differences in the importance assigned to the criteria of several types of VCs and investments. Findings - The study reveals that personality and experience of the entrepreneur and of the management team are the most valued groups of criteria. VCs with a majority of private share capital value more the personality of the entrepreneur and management team than the companies with a majority of public share capital. Additionally, the VCs that did not yet internationalize consider the personality of the entrepreneur and management team and the financial aspects, to be more important than the VCs that have already expanded abroad. Originality/value – It provides evidence on the VCs behaviour in a small venture capital market. Since most of the existing literature on this area refer to large VC markets, the present study is important to investigate whether the conclusions reached by the previous studies can be extended to a small VC market. Also, this study is a contribution to the literature on the internationalization of VCs and it is the first study that explores the impact of the VCs being internationalized on the value given to the various selection criteria of early stage venture capital projects

The impact of concentration among venture capitalists:revisiting the determinants of venture capital

This article analyzes the impact of the level of concentration among Venture Capitalists (VCs) on the supply of venture capital (VC), through the reduced form model for the equilibrium amount of VC (using a simultaneous equation model on aggregated data from 15 European countries). It is shown that the level of concentration among VCs has a positive effect on VC supply, so creating condi-tions to increase the level of concentration can stimulate VC supply. The findings reveal the importance of unemployment and personal income rate on VC demand and the positive impact of stock market capitalization on VC supply.info:eu-repo/semantics/publishedVersio

Performance of fly ash-based geopolymer mortar

This study has investigated the joint effect of several mix parameters on the properties of foam geopolymers. The mix parameters analysed through a laboratory experiment of 54 different mortar mixes were, sodium silicate/sodium hydroxide mass ratio (2.5, 3.5, 4.5), activator/binder mass ratio (0.6, 0.8, 1.0), chemical foaming agent type (hydrogen peroxide (H2O2) and sodium perborate (NaBO3)) and foaming agent mass ratio content (1%, 2%, 3%). Properties, SEM and FTIR analysis and cost analysis are included. The results show that the sodium perborate over performs hydrogen peroxide leading to a lower overall thermal conductibility of foam geopolymers. The use of an activator/binder ratio of 0.8 a sodium silicate/sodium hydroxide of 2.5 led to the lowest thermal conductivity. Mixtures with a low thermal conductivity of around 0.1 W/(m.ºK) and a compressive strength of around 6 MPa were achieved. The cost analysis show that the foaming agents are responsible for a small percentage of foam geopolymers total cost (less than 10%) being that the alkaline activators are responsible for more than 80
