In this survey, I review the academic and policy‐oriented literature on the linkages between financial markets and the rest of the economy. First, I summarize the leading economic theories for why the financial sector can influence the macroeconomy. Second, I consider empirical research on spillovers from the financial sector to the rest of the economy, as well as across financial markets in different countries. Third, I discuss key monetary policy debates regarding the appropriate response of central banks to financial conditions. Finally, I conclude with an overview of the major gaps in the existing literature. 相似文献

Abstract. This paper addresses the concept of market efficiency, presenting a critical review of the conventional tests in the area, which in turn provides the justification for employing an experimental methodology. The literature on experimental asset markets within finance is then reviewed and evaluated. 相似文献

Abstract. Environmental sustainability indices, such as the Dow Jones Sustainability Indexes and the Ethibel Sustainability Index, quantify the development and promotion of sustainable social, ethical and environmental values in the community. Moreover, such indices provide a benchmark for managing sustainability portfolios, and developing financial products and services that are linked to sustainable economic, environmental, social and ethical criteria. This paper reviews the existing data and risk indices in environmental finance. The main purpose of the paper is to analyse existing sustainability and ethical indices in environmental finance, and evaluate empirical environmental risk by estimating conditional volatility clustering that is inherent in these indices. Financial volatility models are estimated to analyse the underlying conditional volatility or time-varying risk that is inherent in alternative environmental sustainability indices. Volatility clustering is observed for most series, but some extreme observations are also evident. The log- and second-moment conditions suggest that valid inferences can be drawn for purposes of sensible empirical analysis. 相似文献
