Dynamic Portfolio Selection by Augmenting the Asset Space

We present a novel approach to dynamic portfolio selection that is as easy to implement as the static Markowitz paradigm. We expand the set of assets to include mechanically managed portfolios and optimize statically in this extended asset space. We consider “conditional” portfolios, which invest in each asset an amount proportional to conditioning variables, and “timing” portfolios, which invest in each asset for a single period and in the risk‐free asset for all other periods. The static choice of these managed portfolios represents a dynamic strategy that closely approximates the optimal dynamic strategy for horizons up to 5 years.     

Why does the velocity of money move pro‐cyclically?

The velocity of money usually rises in expansions and falls in recessions This paper explains this pro‐cyclical movement of velocity using two ideas: (i) during business cycles the movement of investment and consumption of durable goods has a larger amplitude than consumption of non‐durable goods and services; (ii) the velocity associated with expenditure on investment and durable goods is much higher than the velocity associated with consumption of non‐durable goods and services, because the former expenditures are synchronized with the attainment of money by economic agents whereas the latter are not. In this setting, the rise in the weight of expenditure in durable goods relative to the weight of non‐durable goods and services, which occurs during expansions, generates an increase in the average velocity of circulation. The opposite happens during recessions and thus velocity moves pro‐cyclically.     

Diagnostic Expectations and Credit Cycles

We present a model of credit cycles arising from diagnostic expectations—a belief formation mechanism based on Kahneman and Tversky's representativeness heuristic. Diagnostic expectations overweight future outcomes that become more likely in light of incoming data. The expectations formation rule is forward looking and depends on the underlying stochastic process, and thus is immune to the Lucas critique. Diagnostic expectations reconcile extrapolation and neglect of risk in a unified framework. In our model, credit spreads are excessively volatile, overreact to news, and are subject to predictable reversals. These dynamics can account for several features of credit cycles and macroeconomic volatility.     

Favoritism in Mutual Fund Families? Evidence on Strategic Cross‐Fund Subsidization

We investigate whether mutual fund families strategically transfer performance across member funds to favor those more likely to increase overall family profits. We find that “high family value” funds (i.e., high fees or high past performers) overperform at the expense of “low value” funds. Such a performance gap is above the one existing between similar funds not affiliated with the same family. Better allocations of underpriced initial public offering deals and opposite trades across member funds partly explain why high value funds overperform. Our findings highlight how the family organization prevalent in the mutual fund industry generates distortions in delegated asset management.     

The Role of Institutional Investors in Voting: Evidence from the Securities Lending Market

This paper investigates voting preferences of institutional investors using the unique setting of the securities lending market. Investors restrict lendable supply and/or recall loaned shares prior to the proxy record date to exercise voting rights. Recall is higher for investors with greater incentives to monitor, for firms with poor performance or weak governance, and for proposals where returns to governance are likely higher. At the subsequent vote, recall is associated with less support for management and more support for shareholder proposals. Our results indicate that institutions value their vote and use the proxy process to affect corporate governance.
