This paper studies whether and how the central bank should prick asset price bubbles, if the effect of interest rate policy on bubbles can significantly vary across periods. For this purpose, I first construct a financial accelerator model with an agent-based financial market that can...

Three conditions are suggested for establishing a stable financial system: 1. Only digital money is used. 2. The Internet of Things (IoT) uses a sustainable service of nature essential to maintain the well being of the environment and humans in each region of the planet to automatically...

We present a dynamic Rational Expectations (RE) bubble model of prices with the intention to evaluate it on optimal investment strategies applied to Bitcoin. Our bubble model is defined as a geometric Brownian motion combined with separate crash (and rally) discrete jump distributions associated...

We present a self-consistent model for explosive financial bubbles, which combines a mean-reverting volatility process and a stochastic conditional return which reflects nonlinear positive feedbacks and continuous updates of the investors' beliefs and sentiments. The conditional expected returns...

Some key features in the historical dynamics of U.S. Treasury bond yields-a trend in long-term yields, business cycle movements in short-term yields, and a level shift in yield spreads-pose serious challenges to existing equilibrium asset pricing models. This paper presents a new equilibrium...

Equilibrium bond-pricing models rely on inflation being bad news for future growth to generate upward-sloping nominal yield curves. We develop a model that can generate upward-sloping nominal and real yield curves by instead using ambiguity about inflation and growth. Ambiguity can help resolve...

Recent findings on the term structure of equity and bond yields pose serious challenges to existing models of equilibrium asset pricing. This paper presents a new equilibrium model of subjective expectations to explain the joint historical dynamics of equity and bond yields (and their yield...

This paper relates to the literature on macro-finance-interaction models. We modify the boundedly rational New Keynesian model of De Grauwe (2010a) using a completely microfounded IS equation, and combine it with the agent-based financial market model of Westerhoff (2008). For this purpose we...

The failure of Lehman Brothers highlighted the severe lapses in risk management and regulatory oversight that brought on and intensified the global financial crisis. This paper presents a structural credit risk model that provides useful early warning signals that regulators could have used to...
