Attention to 'sustainability' and energy efficiency rating schemes in the commercial property sector has increased rapidly during the past decade. In the UK, commercial properties have been certified under the BREEAM rating scheme since 1999, offering fertile ground to investigate the economic dynamics of 'green' certification in the commercial property market. This paper documents that, over the 2000-09 period, the expanding supply of green buildings within a given London neighbourhood had a positive impact on average rents and prices, but reduced rents and prices for environmentally certified real estate. The results suggest that there is a gentrification effect from green buildings. However, each additional ''green'' building decreases the marginal effect of certification in the rental and transaction markets by 2 per cent and 5 per cent respectively. In addition, controlling for lease contract features, like contract length and the rent-free period, modifies the impact of environmental certification on rental prices.

We review the socially responsible investment (SRI) mutual fund performance literature to provide best practices in SRI performance attribution analysis. Based on meta-ethnography and content analysis, five themes in this literature require specific attention: data quality, social responsibility verification, survivorship bias, benchmarking, and sensitivity and robustness checks. For each of these themes, we develop best practices. Specifically, for sound SRI fund performance analysis, it is important that research pays attention to dividend yields and fees, incorporates independent and third party social responsibility verification, corrects for survivorship bias and tests multiple benchmarks, as well as analyzing the impact of fund composition, management influences and SRI strategies through sensitivity and robustness analysis. These best practices aim to enhance the robustness of SRI financial performance analysis.

This paper investigates spatial dependence in the prices of office buildings in Hong Kong, London, Los Angeles, New York City, Paris, and Tokyo for 2007 to 2013. Compared to prior literature, we find low economic impact from spatial dependence in all six markets, and spatial and spatialtemporal dependence do not moderate the effects of hedonic characteristics statistically or economically. However, investor and seller types as well as neighborhood location have a significant impact on the economic and statistical significance of the spatial and spatial-temporal parameters. Spatial office price indices for London, Paris and Tokyo decline somewhat more than do hedonic indices during the crisis.
