The investment strategies of publicly sponsored venture capital funds

This paper investigates the effects of public ownership on the investment strategy of hybrid VC funds. We exploit a unique dataset containing data for all of the venture capital funds in Europe that received financial support from the European Investment Fund (EIF) during the years 1998–2007. The dataset includes 179 VC funds that invested in 2482 companies. We find that the level of public ownership shows a weak negative correlation with the likelihood of observing a write-off and that a higher public share is associated with a longer duration for the investment. The latter effect is more relevant for those investments that generate intermediate financial returns. The results are robust to the introduction of controls at the target firm level and for financial market conditions.     

Monetary policy rules and directions of causality: A test for the euro area

Abstract

Using a VAR model in first differences with quarterly data for the euro zone, the study aims to ascertain whether decisions on monetary policy can be interpreted in terms of a “monetary policy rule” with specific reference to the so-called nominal GDP targeting rule (Hall and Mankiw, 1994 Granger, C.W.J. “Investigating Causal Relations by Econometric Models and Cross-Spectral Methods.” Econometrica, 1969, 37 (3), 424–438.[Crossref], [Web of Science ®] , [Google Scholar]; McCallum, 1988 McCallum, B. “Nominal GDP Targeting”, Shadow Open Market Committee, October 21, 2011. [Google Scholar]; Woodford, 2012 Taylor, J.B., Williams, J.C. “Simple and Robust Rules for Monetary Policy”, NBER Working Paper No. 15908, April, 2010. [Google Scholar]). The results obtained indicate a causal relation proceeding from deviation between the growth rates of nominal gross domestic product (GDP) and target GDP to variation in the three-month market interest rate. The same analyses do not, however, appear to confirm the existence of a significant inverse causal relation from variation in the market interest rate to deviation between the nominal and target GDP growth rates. Similar results were obtained on replacing the market interest rate with the European Central Bank refinancing interest rate. This confirmation of only one of the two directions of causality does not support an interpretation of monetary policy based on the nominal GDP targeting rule and gives rise to doubt in more general terms as to the applicability of the Taylor rule and all the conventional rules of monetary policy to the case in question. The results appear instead to be more in line with other possible approaches, such as those based on post Keynesian analyses of monetary theory and policy and more specifically the so-called solvency rule (Brancaccio and Fontana, 2013 ———. Macroeconomics, 2nd ed., Pearson Education Company, ch. 30. [Google Scholar], 2015 Brancaccio, E. The Central Banker as “Regulator” of Conflict. In G. Fontana and M. Setterfield (eds.), Macroeconomic Theory and Macroeconomic Pedagogy. Basingstoke: Palgrave Macmillan, 2009, 295–308.[Crossref] , [Google Scholar]). These lines of research challenge the simplistic argument that the scope of monetary policy consists in the stabilization of inflation, real GDP, or nominal income around a “natural equilibrium” level. Rather, they suggest that central banks actually follow a more complex purpose, which is the political regulation of the financial system with particular reference to the relations between creditors and debtors and the related solvency of economic units.     

Explanatory analysis of the key factors in an energy sustainability index

The need to reduce the emissions of greenhouse gases in energy generation has led to international and national bodies recommending and encouraging a series of policies and measures to boost so-called green energy generation and achieve sustainability in the energy sector. In order to assess the energy sustainability path of countries worldwide, we first propose a dynamic analysis of an energy sustainability index (ESI) based on the methodology of composite indicators built on a large dataset of 136 heterogeneous countries and 38 variables observed in 3 years (2000, 2005 and 2011). Second, to isolate the influence of socio-demographic and economic characteristics on the energy sustainability of countries, we perform quantile regression with clustered data. Our findings demonstrate that major changes are required in developing countries, where development is pursued mainly through the use of energy sources based on fossil fuels. To ensure access to sustainable energy, policy makers need to consider and improve the key factors according to the ESI’s quantiles. In particular, human development variables (i.e., life expectancy and the percentage of completed secondary schooling attained in the population) and the variables related to civil rights and institutions (e.g., percentage of women in national parliaments) are crucial in promoting energy sustainability. By contrast, high unemployment rates, high congestion costs and the continued use of highly polluting energy sources have the effect of reducing energy sustainability.     

A Pure Theory of Job Security and Labour Income Risk

Models of labour market equilibrium where forward-looking decisions maximize both profits and labour income on a risk-neutral basis offer valuable insights into the effects of employment protection legislation. Since risk-neutral behaviour in the labour market presumes perfect insurance, however, job security provisions plays no useful role in such models. This paper studies a stylized model of dynamic labour market interactions where labour reallocation costs are partly financed by uninsured workers' consumption flows. In the resulting second-best equilibrium, provisions that shift labour reallocation costs to risk-neutral employers can increase productive efficiency if their administrative dead-weight costs are not too large, and increase workers' welfare as long as employers' firing costs at least partly finance workers' mobility.
