We provide heterogenous agent foundations for regime-switching tests of asset price bubbles, and illustrate by applying the models to historical U.S. stock market data. While the tests remain unchanged, we show the specification of regimes can be based on the beliefs of investors that come from...

We find that incorporating nonlinearities into tests of asset price bubbles has important consequences for the results. We show this by comparing four tests using S&P 500 data. Our results indicate that the modification which incorporates nonlinear probabilities outperforms the other models in...

Obtaining reliable data on capital is a recurring challenge when estimating economy-wide productivity growth, especially for developing countries. In this paper I construct energy-based productivity series which use energy consumption instead of capital when making such estimates. I first show...

We conduct a pseudo real-time analysis of the existence and severity of speculative bubbles in eleven US sectors over the period 1973-2015. Based on the real-time bubble signals, a trading strategy is constructed which switches funds between the market index and those industry sectors that...
