ABSTRACT: This paper serves as an introduction to a Special Issue (SI) of the Journal of Forest Policy and Economics dedicated to forest investment and finance. The Special Issue stemmed from an International Forest Business Conference (IFBC2018) held in Poland on 6-8 June 2018. It includes papers based on speeches at that conference, as well as others on similar topics not presented at the conference. Topics addressed in this Special Issue include timberland investments, forest finance, intensively managed plantations, risk, uncertainty and decision-making, business structures and investment strategy, timber prices and forecasts, forestry contractors, and taxes. Details papers on these subjects follow in this Special Issue. Our finance research overview here provides a historical background and summary of forest investments and finance, focusing on forest equity investments made by institutional investors and in forestry real estate investment trusts, not including public lands or individual small private forest landowners. Forest assets as an investment class have expanded due to analytical advances, ownership changes, globalized markets, and sustainable forestry factors. Key components affecting forestry investments are expected asset returns, portfolio diversification, inflation hedge, and liquidity and natural risks. Topics detailed in this Special Issue include timberland investments, forest finance, intensively managed plantations, risk, uncertainty and decision-making, business structures and investment strategy, timber prices and forecasts, forestry contractors, and taxes. Finally, we identify knowledge gaps regarding forest investments for future research.
