I am a professor of finance at the Merage School of Business, UC Irvine. My research interests include behavioral economics and finance, the theory of social interactions, and cultural evolution.
My Approach to Ethical Systems:
My first angle on ethical systems concerns how moral intuitions and feelings affect financial decisions. Behavioral finance has focused mainly on how cool cognitive biases affect investor decisions, market prices, and firm behavior. Moral attitudes infuse our thinking about how much to save (as in Aesop’s fable of the ant and the grasshopper), when to bear risk (compare the moral connotations of the terms 'entrepreneur,' 'speculator,' or 'gambler'), and how to treat others (is it fair to exploit an informational advantage? intentionally default on your mortgage?)
These three categories of decisions (how much to save versus consume, what kind of risks to bear, and conflicts of interest or `agency problems’ between market participants) cover almost all of finance. This highlights the importance of integrating moral attitudes into the study of finance.
Second, I’m interested in how moral attitudes bias the process by which beliefs are transmitted from person to person; and on how transmission biases affect the spread of moral attitudes.
As an example of the first possibility, when bears sell short a firm’s stock, the apparent harm is concrete and fits easily under a moralistic rubric of 'profiting from the misfortune of others.' The benefit of short selling, making the price of the stock more informationally efficient, is abstract, and therefore not nearly as attractive for use in casual conversation. As such, negative beliefs about short selling spread at the expense of positive ones. So moral attitudes induce transmission biases that can affect social outcomes, such as regulation.
