We propose a theory of asset prices that emphasizes heterogeneous information as the main element determining prices of different securities. Our main analytical innovation is in formulating a model of noisy information aggregation through asset prices, which is parsimonious and tractable, yet...

Recent research on financial market valuation of the knowledge assets of publicly traded firms is surveyed. The motivation for using a market value equation to price knowledge assets is discussed and the theory behind this equation is briefly presented. Then the empirical literature that relates...

This paper examines the relationship between inflation and the return on individual corporate securities. This question is of substantial importance in light of the puzzling behavior of the stock market over the last decade. Conventional financial theory holds that equity should be a good...

On June 22, 2020, President Trump issued an Executive Order (EO) that suspended new work visas, barring nearly 200,000 foreign workers and their dependents from entering the United States and preventing American companies from hiring skilled immigrants using H-1B or L1 visas. Exploiting this...

This paper presents clinically-based studies of two acquisitions that received very different stock market reactions at announcement one positive and one negative. Despite the differing market reactions, we find that ultimately neither acquisition created value overall. In exploring the reasons...

This paper decomposes both the market sensitivity and the interest-rate sensitivity of bank stock into on-balance-sheet and off-balance-sheet components. It derives these constituent and often-offsetting sensitivities from a nonstationary three-equation model that employs accounting and...

We present an alternative expectation formation mechanism that helps rationalize well known asset pricing anomalies, such as the predictability of excess returns, excess volatility, and the equity-premium puzzle. As with rational expectations (RE), the expectation formation mechanism we consider...

Poor financial health of intermediaries coincides with low asset prices and high risk premiums. Is this because intermediaries matter for asset prices, or simply because their health correlates with economy-wide risk aversion? In the first case, return predictability should be more pronounced...

This paper examines an economy in which aggregate shocks are not dispersed equally throughout the population. Instead, while these shocks affect all individuals ex ante, they are concentrated among a few ex post.The equity premium in general depends on the concentration of these aggregate...

Fama(1984) analyzed the variability and the covariation of risk premiums and expected rates of depreciation. We employ three statistical techniques that do not suffer from a potential bias in Fama's analysis, but we nevertheless confirm his findings. In contrast to his interpretation the results...
