We analyze whether firms that receive venture capital (VC) at a later date face more financial constraints than a one-by-one matched sample of firms that did not receive VC funding (control group). The aim is to check whether their financial flexibility explains why they decide to seek external equity funding. In contrast with other papers, which focus on the sensitivity of investments to cash flow, we study this issue by applying a dynamic model to analyze the speed of adjustment to their target debt levels prior to receiving the first VC investment. We analyze a representative sample of 237 Spanish unlisted firms that received VC between 1995 and 2007 and its corresponding control group. We find that firms that receive VC funding show a significantly lower speed of adjustment than their matched peers before the initial VC round. It seems that the former are more concerned about funding the required investments than about adjusting the firm's debt ratio to a target level. Our results confirm the role of VC in filling the equity gap in constrained unlisted firms. From a capital structure perspective, VC may become a tool for these companies to balance their capital structure in a growth process. 相似文献

This paper investigates the relationship between federal election outcomes and expected returns and volatilities in the Canadian money, bond, equity and currency markets from 1951 to 2006. There is little evidence that investment opportunities are different in minority versus majority parliaments and only money market returns differ in Conservative versus Liberal governments. The equity market performs better in the late part of the electoral cycle than in the first two years. Furthermore, the Canadian equity investment opportunities are better in Democratic versus Republican administrations and in the late versus early parts of the presidential electoral cycle. The Canadian dollar is also affected by American election outcomes. No apparent variation in risk or expected state of the economy accounts for the differences in returns. 相似文献

ABSTRACTThe conservation enterprise is embedded in ideas of the environment through which it promotes a vision of the world and the relations between the non-human and human. The papers in this forum analyse conservation from various vantage points to draw the links between geopolitics and conservation. The authors use three themes to demonstrate these links. The first theme draws on the concept of environmentality to show the mobilization of ecological rationalities and power towards the creation of protected areas. The second pays attention to networks formed across the distance, and how they influence the location and governance of protected areas. The third focuses on the strategies the conservation lobby uses to align local identities with global conservation ideals and goals. Collectively, these themes highlight features of conservation geopolitics. 相似文献

This paper examines the relationships amongst volatility, total trading volume (TVOL) and total open interest (TOI) for three Taiwan stock index futures markets as well as the role of the latter two variables in the dynamics of GARCH modeling and forecasting. From both ex-post and ex-ante perspectives, we study this issue by using the VAR model and augmented GARCH-type models, respectively. For the GARCH-type models, we employ both symmetric and asymmetric models augmented with lagged logs in TOI and/or TVOL. We find that whether addition of these two variables helps the basic GARCH models predict future volatility depends upon the sample period examined for all three sets of futures. Nonetheless, the best three models for out-of-sample volatility forecasting in the MSE sense are generally the augmented models for all sub-intervals and all three futures contracts. 相似文献

AbstractA climate of presenteeism has important effects on employee well-being and the organization itself. Our study, based on surveys of health sector employees in six different countries (Brazil, Ecuador, Lebanon, Portugal, Russia and Spain) examines whether organizational justice plays a mediating role in the relationship between a presenteeism climate in the organization and work–family conflict (WFC). Our results indicate that the perception of organizational justice and the presenteeism climate do influence WFC. Moreover, higher levels of WFC were found in non-Latin countries. This study contributes to the work attendance and life balance field by providing cross-cultural empirical evidence corroborating the effect of justice and presenteeism climate on the WFC. 相似文献

Even though electrical companies attain a top ranking in the publication of CSR reports, they are often accused of 'green‐washing' due to their bad environmental reputation. The current economic crisis is testing their real CSR commitment more than ever, especially when this goes beyond its economic consequences. Based on a worldwide sample of electrical companies, we are going to study why companies are being socially responsible. We wish to know if it is due to the impact on the firms' performance or whether there are other motives (legitimation, improving their reputation) that lead companies to carry out these practices. We will also consider if it changes across the kind of CSR action considered. The results show that there is an economic justification beyond the socially responsible behaviour of the electrical companies. Additionally, most kinds of CSR action (community, diversity, corporate governance, product responsibility) are also carried out looking for economic rewards. However, the CSR actions oriented to the environment are mainly motivated by their need to improve their image and reverse their negative impact.

Using quarterly call report data from 2000 to 2016, we reexamine the relationship between net interest margins (NIM) and the yield curve for more than 5,500 U.S. commercial banks. In the full sample, yield curve and RGDP growth have positive effects on NIM, while inflation and deposit‐to‐loan ratios (D/L) have negative effects. Splitting the sample around the 2007–2009 crisis, we show the impact of yield curve and RGDP growth on NIM increasing during the “recovery” (2009Q3 to 2016Q4), and inflation and D/L changing signs. Positive effects of yield curve on profits vary with bank size and change over time. 相似文献

This paper focuses on the resolution of bond market crises. Episodes of bond market distress are identified using secondary market sovereign bond spreads. Duration models are used to assess the role of the global environment, domestic policy, IMF programs and political events in explaining the length of distress episodes. We find a rich set of interactions between favourable external conditions, sound macroeconomic policies and the presence of an IMF program which contribute to shorter bond market crises. 相似文献

This paper studies the spread between 10 year Euro denominated Central and Eastern European (CEE) government bonds and their German counterpart. With newly available time series, regressions are run for each country separately in order to deliver a first insight into the underlying determinants. While higher ECB reference rate and market volatility increase bond spreads and turn out to be the main driving factors, there is no common pattern of macroeconomic fundamentals, pointing to strong heterogeneity within the CEE region. Overall, market variables are more significant than fundamentals during 1999 to 2007. 相似文献

We analyse the interaction between the dividend policy and the decision on investment in a growth opportunity of a liquidity
constrained firm. This leads us to study a mixed singular control/optimal stopping problem for a diffusion that we solve quasi-explicitly
by establishing a connection with an optimal stopping problem. We characterize situations where it is optimal to postpone
the distribution of dividends in order to invest at a subsequent date in the growth opportunity. We show that uncertainty
and liquidity shocks have an ambiguous effect on the investment decision.
