We give an explicit algorithm and source code for combining alpha streams via bounded regression. In practical applications, typically, there is insufficient history to compute a sample covariance matrix (SCM) for a large number of alphas. To compute alpha allocation weights, one then resorts to...

We embed adverse selection into a dynamic, general equilibrium model with heterogeneous capital and study its implications for aggregate dynamics. The friction leads to delays in firms' divestment decisions and thus slow recoveries from shocks, even when these shocks do not affect the economy's...
