Infrastructure as an asset class 1. Infrastructure assets: Demand, definition, and investment characteristics
Terms of use:
Documents inInvesting in public infrastructure has become popular with institutional and private investors in recent years. A growing number of specialist products were launched by the financial industry to satisfy the demand for infrastructure as a new asset class with a number of attractive and distinctive investment characteristics.Can infrastructure investments live up to the promise? Despite the action seen in recent years, the field is still very much under-researched. This is surprising, given the political, economic, financial, social, and also cultural, relevance of infrastructure, and the potential contribution of private finance to longterm investment.We still know very little, both in theory and in practice. Private investors' experience with infrastructure funds is rarely longer than four to five years, and is shaped by the boom-bust-environment in financial markets. There are a number of issues that confuse investors and researchers alike.Research was initially undertaken primarily by product providers (see Inderst 2009 for an overview of the earlier literature). Over the last one or two years, a number of new books and articles have been published in this field. However, data are still very limited in quantity and quality, making empirical work difficult. More surprisingly, there is hardly any theoretical work done on the subject.This article sheds some light on the question whether infrastructure-related financial assets are distinct enough to form an asset class on their own. It discusses the empirical literature on return, risk and other characteristics of infrastructure-related financial assets and presents new empirical results on the issue.The remainder of this section gives some background on the demand for infrastructure assets, their definition and investment characteristics. Section 2 introduces investment vehicles and provides facts and figures for the growing investment volumes. Section 3 looks at investors' asset allocation to infrastructure. Section 4 discusses the risk-return profile and specific risks. Section 5 reviews the evidence available on the historical performance of infrastructure investments. Section 6 undertakes a new analysis of the net returns of unlisted infrastructure funds on a global scale. Section 7 discusses the diversification potential and optimal portfolio allocation. Section 8 pre...
