A transparent approach to solving linear rational expectation models
Economica, EarlyView.Abstract This paper proposes a simple iterative method—time iteration—to solve linear rational expectation models. I prove that this method converges to the desired stable solution, and provide the conditions under which the solution is unique. Apart from its transparency and simplicity of implementation, the method provides a straightforward approach ...

Estimating Hedge Fund Leverage: A Three‐Step Estimation Protocol
Financial Markets, Institutions &Instruments, EarlyView.ABSTRACT Utilizing a micro‐level hedge fund dataset, we propose a methodology for estimating hedge fund leverage. Initially, we perform a Principal Component Analysis on a set of 49 risk factors for dimension deduction purposes. After acquiring 10 Principal Components, we deploy the Least Absolute Shrinkage and Selection Operator regression (Lasso) per

The Unemployment‐Risk Channel in Business‐Cycle Fluctuations
International Economic Review, EarlyView.ABSTRACT The unemployment‐risk channel (URC) amplifies an initial contraction through a reduction in consumption demand by workers who fear unemployment. Crucial for this are the dynamics of job separations and firm hiring. In US data, the job‐finding rate responds slower to identified macroeconomic shocks than the separation rate, but accounts for a ...
