portfolio holdings evolve over time at the first order. For simple models, optimal portfolios may be derived analytically. For more complex models, the paper provides a simple, one step, computationally efficient approach to generating numerical results. 4 The approach to characterizing portfolio dynamics here is based on Taylor-series approximation of a model’s equilibrium conditions. The standard log-linear approximation procedures used in macroeconomics can not be directly applied to portfolio problems. This is for two reasons. Firstly, the equilibrium portfolio is

Portfolio Dynamics—Size and Concentration 1 Prior to the COVID-19 pandemic, emerging economies increasingly saw portfolio debt inflows from a type of large international investment fund: multi-sector bond funds (MSBFs) . The assets of the funds in a sample of 40 large MSBFs have more than doubled since the global financial crisis to about $1 trillion (nearly 10 percent of the entire bond investment fund sector globally). Their aggregate emerging market investment has ranged between $100 billion-$160 billion in recent years (peaking at about $160 billion in
