Technological innovation is not a blessing for all firms, or for investors holding the market. In the late 20th century US, individual firms' stock returns correlate positively with their own productivity growth, yet the market return correlates negatively with aggregate productivity growth,...

Shareholder valuations are economically and statistically positively correlated with more powerful independent directors, their power gauged by social network power centrality measures. Sudden deaths of powerful independent directors significantly reduce shareholder value, consistent with...

Family firms depend on a succession of capable heirs to stay afloat. If talent and IQ are inherited, this problem is mitigated. If, however, progeny talent and IQ display mean reversion (or worse), family firms are eventually doomed. This is the essence of the critique of family firms in...

The fundamental unit of production in microeconomics is the firm, and this mirrors reality in the United States and United Kingdom. But elsewhere, business groups can be the more important unit, for business strategy is often formulated at the business group level, not the firm level. In many...

Economics has firms maximizing value and people maximizing utility, but firms are run by people. Agency theory concerns the mitigation of this internal contradiction in capitalism. Firms need charters, regulations and laws to restrain those entrusted with their governance, just as economies need...

Different economies at different times use different institutional arrangements to constrain the people entrusted with allocating the economy's capital and other resources. Comparative financial histories show these corporate governance regimes to be largely stable through time, but capable of...

Many seemingly discordant results are reconciled if firm-specific return volatility is characterized as the intensity with which firm-specific events occur. A functionally efficient stock market allocates capital to its highest value uses, which often amounts to financing Schumpeterian creative...

We examine information spillover as a source of stock return synchronicity, where information about highly-followed "prominent" stocks is used to price other "neglected" stocks sharing a common fundamental component. We find that stocks followed by few analysts co-move significantly with...

Using complete order books from the Korea Stock Exchange for a four-year period including the 1997 Asian financial crisis, we observe (not estimate) limit order demand and supply curves for individual stocks. Both curves have demonstrably finite elasticities. These fall markedly, by about 40%,...
