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,...

Within countries, state-run banks' lending correlates with prior money growth; otherwise similar private-sector banks' lending does not. Aggregate credit and investment growth correlate with prior money growth more where banking systems are more state-run. Size and liquidity differences between...

Where legal systems and market forces enforce contracts inadequately, vertical integration can circumvent these transaction difficulties. But, such environments often also feature highly interventionist government, and even corruption. Vertical integration might then enhance returns to political...

Many countries appear to have excessively stable big business sectors, in that higher rates of big business turnover have been correlated with faster economy growth. Public policies that stabilize big business sectors are sometimes justified as supportive of social objectives. We find no...

Rosenstein-Rodan (1943) and others posit that rapid development requires a 'big push' -- the coordinated rapid growth of diverse complementary industries, and suggests a role for government in providing such coordination. We argue that Japan's zaibatsu, or pyramidal business groups, provided...

What is good for big business need not generally advance a country%u2019s overall economy. Big business turnover correlates with rising income, productivity, and (in high income countries) faster capital accumulation; consistent with Schumpeter%u2019s (1912) creative destruction and recent...

Around the world, large corporations usually have controlling owners, who are usually very wealthy families. Outside the U.S. and the U.K., pyramidal control structures, cross shareholding and super voting rights are common. Using these devices, a family can control corporations without making a...

The efficient markets hypothesis implies that passive indexing should generate as high a return as active fund management. Indexing has been a very successful strategy. We document a large value premium in the average q ratios of firms in the Samp;P 500 index relative to the q ratios of other...

We observe less efficient capital allocation in countries whose banking systems are more thoroughly controlled by tycoons or families. The magnitude of this effect is similar to that of state control over banking. Unlike state control, tycoon or family control also correlates with slower...
