In this paper, we propose a novel simultaneous two-dimensional continuous-time Markov chain (CTMC) approximation method, in contrast to the existing double-layer approach, to approximate the general fully coupled Markov diffusion processes which cover all the classical models. Extensive...

This paper proposes an intermediary-based explanation of the risk premium of currency carry trade in a model with a cross-section of small open economies. In the model, bankers in each country lever up and hold interest-free cash as liquid assets against funding shocks. Countries set different...

We provide a review of macro-finance models featuring nonlinear dynamics. We survey the models developed recently in the literature, including models with amplification effects of financial constraints, models with households' leverage constraints, and models with financial networks. We also...

We propose and estimate a quantitative model of exchange rates in which the participantsin the FX market are intermediaries subject to value-at-risk (VaR) constraints. Higher volatilitytranslates into tighter VaR constraints, and intermediaries require higher returns to holdforeign assets....
