The different roles played by venture capital and private equity investors on the investment activity of their portfolio firms

Venture capital (VC) and private equity (PE) investors play different roles in their portfolio companies. We argue that this will translate in a recognizable difference in the investment sensitivity to cash flows of portfolio companies and its evolution after the first investment round. We hypothesise that VC, thanks to its ability in overcoming asymmetries in information, will entail a reduction in the financial constraints which hampered the growth of investee firms. We predict, instead, a greater dependency of investments to cash flow for PE-backed companies, driven by the renewed interest for growth of their management combined with higher leverage. We find evidence confirming our hypotheses on a large panel of Spanish unlisted firms in low and medium technology sectors, where both VC and PE firms are active.     

Improving the Performance of a Long‐Run Variance Ratio Test for a Unit Root

Cai and Shintani (2006, Econometric Theory, 22, 347–372) considered the impact of introducing an inconsistent long‐run variance estimator when constructing a class of kernel‐based ratio tests for testing non‐stationarity in the series. They found that the quotient of two estimators with different rates of convergence under the null and the alternative hypotheses may lead to a test having an interesting size and power trade‐off. This paper develops modified versions of this test, presents new asymptotic results and tabulates critical values. The finite sample performance is explored through Monte Carlo simulations. The results show that the modifications proposed lead to more powerful unit root tests.     

Consumer confidence indices and stock markets' meltdowns

Consumer confidence indices (CCIs) are a closely monitored barometer of countries' economic health and an informative forecasting tool. Using European and US data, we provide a case study of the two recent stock market meltdowns (the post-dotcom bubble correction of 2000–2002 and the 2007–2009 decline at the beginning of the financial crisis) to contribute to the discussion on their appropriateness as proxies for stock markets' investor sentiment. Investor sentiment should positively covary with stock market movements [DeLong, Shleifer, Summers, and Waldmann. 1990. “Noise Trader Risk in Financial Markets.” Journal of Political Economy 98 (4): 703–738]; however, we find that the CCI–stock market relationship is not universally positive. We also do not find support for the information effect documented in the previous literature, but identify a more subtle relationship between consumer expectations about future household finances and stock market fluctuations.     

General and specific cancer risk perceptions: how are they related?

Understanding how people construe and act upon cancer risk is important for efforts to target risk-increasing health behaviors. Importantly, research participants are often asked to estimate their risk for cancer (in general), which could mask the fact that cancer represents a range of diseases, and that different cancer types can have distinct risk factors. It is unclear whether individuals perceive general cancer risk as being comprised of an aggregation of risk for specific cancer sites, or whether general cancer risk perceptions reflect the specific type of cancer most salient to them. In this study, general cancer risk perceptions were regressed on specific risk perceptions for colon, lung, prostate (men only), and breast (women only), using data from a nationally representative sample. We found that among men and women, all forms of cancer predicted independent variance in estimates of general cancer risk. There were also stronger relationships between general risk perceptions and each specific risk perception than between any two specific risk perceptions, suggesting that individuals differentiate between specific cancers and general cancer risk. These findings offer some confidence that people’s estimates of general cancer risk take multiple cancer types into account.

Impact of high‐growth start‐ups on entrepreneurial environment based on the level of national economic development

In this paper, we examine the relationship between the conditions of the entrepreneurial environment and high‐potential entrepreneurship according to the stage of economic development of the country. A structural equation model was designed based on data from the Global Entrepreneurship Monitor project, which contains information about 62 countries. Our results suggest that economic development and high‐potential entrepreneurship have a greater impact on the entrepreneurial ecosystem than entrepreneurial activity in general—with special effects on government programs, R&D transfer, and access to the domestic market. Notably, the level of influence of sustainable economic development and high‐potential entrepreneurship depends on the level of economic development of the country.     

Is the tourism–economic growth nexus time-varying? Bootstrap rolling-window causality analysis for the top 10 tourist destinations

This article explores the time-varying causal nexus between tourism development and economic growth for the top 10 tourist destinations in the world, namely China, France, Germany, Italy, Mexico, the Russian Federation, Spain, Turkey, the UK and the United States of America, over the period 1990–2015. To that end, a bootstrap rolling window Granger causality approach based on the modified Granger causality test is used. A new index for tourism activity which combines via principal component analysis the commonly used tourism indicators is also employed. The results of the bootstrap rolling window causality tests reveal that the causal relations between tourism and economic growth vary substantially over time and across countries in terms of both magnitude and direction. It is shown that the causal linkages tend to be more pronounced for a large group of countries following the global financial crisis of 2008. Additionally, Germany, France and China clearly stand out as the countries with the weakest causal nexus, while the UK, Italy and Mexico emerge as the countries that have the strongest causal links. These results have particularly important implications for policymakers.     

Industry-level determinants of the linkage between credit and stock markets

This paper examines the relationship between US credit default swaps (CDS) and stock returns on an industry-wide basis across a number of investment horizons, with particular focus on the major determinants of such a relationship. Wavelet analysis is first applied to extract the CDS–stock wavelet correlation for each US industry. Then, Bayesian Model Averaging is employed to identify the key driving factors of the industry CDS–stock wavelet correlations at short- and long-term horizons. The empirical results indicate that the wavelet correlations between the industry CDS and stock returns are primarily negative over time and across time scales. Moreover, the CDS–stock correlation at longer horizons exhibits a much more stable pattern than its counterpart at shorter time frames. The results also demonstrate that the volatility of US Treasury and stock markets, as measured by the MOVE and VIX indices, respectively, the volatility of volatility, as captured by the VVIX index, and US economic policy uncertainty, as measured by the EPU index, are the most robust determinants of the correlation between CDS and stock returns at shorter and longer horizons for most US industries. In contrast, the Fama–French systematic equity factors exhibit a practically negligible explanatory power on the CDS–stock link.     

Analysts herding: when does sentiment matter?

Herding among analysts emerges when analysts give priority to their peers’ opinions instead of their own beliefs or information. Some circumstances may enhance or restrain this type of behaviour. We postulate that market sentiment is one of them. This article analyses the effect that investor sentiment may have on analysts’ herding behaviour in the U.K. Our results suggest that ‘easy situations’ such as analysing easy-to-value securities and releasing optimistic information at times of high market sentiment clearly reduce herding practices, whereas herding clearly increases in difficult situations when analysts have to release negative information at moments of high investor sentiment.     

Social Tourism and Healthy Ageing

Recent research in social tourism notes possible links between tourism participation and improvements in health. However, there is a lack of quantitative evidence concerning the potential links between tourism participation and self‐reported health amongst older people. An ageing society requires measures to promote independent living and enhance older people's quality of life. This paper provides evidence that older tourists are more active and healthy than non‐tourists, from a study comparing health perceptions amongst Spanish older people. The results provide tentative conclusions of causal relationships between tourism and dimensions of physical and mental health through a Structural Equation Model.
