This paper documents a new channel for rating-based bond market segmentation, which, in contrast to prior research, is based on nonregulatory investment management practices. A 2005 Lehman Brothers index redefinition provides a quasinatural experiment in which a number of previously high-yield split-rated bonds were mechanically relabeled as investment grade. Although their regulatory standing was unaffected, these bonds had abnormal yield declines of 21 basis points. These valuation changes can be traced to buying by asset-class-sensitive institutional investors for whom these bonds became investable. Reputation, regulation, indexation, and liquidity cannot explain the observed price and trading patterns.

How are neighboring firms affected when a bank learns more about a given firm? We analyze exchange-rate-induced movements of Peruvian firms across a threshold that governs their regulatory treatment by banks. Firms that cross the threshold supply more information to their banks and experience a substantial increase in financing. We find positive spillover effects: the neighbors of the above-threshold firms also experience increased financing. These spillovers are confined to neighbors sharing a bank, and the performance of new loans to these neighbors improves, suggesting that the bank has become better informed about other local firms.

An entrepreneur, with private information about his firm, contracts over two periods with an outside financier, a venture capitalist (VC) or angel. The financier can reduce his information disadvantage by learning about the firm over time. VC financing is scarce relative to angel financing. Further, unlike an angel, a VC may exert effort, which, together with the entrepreneur’s effort, increases the firm’s success probability. The equilibrium VC financing contract ensures optimal effort-exertion by both entrepreneur and VC. We characterize the firm’s equilibrium choice between VC and angel financing, its equilibrium contractual provisions, and the dynamic evolution of its financing contract.

We analyze the choice between fixed-price offerings and auctions in IPOs and privatizations. We model a firm going public by selling equity in the IPO market. Firm insiders have private information about intrinsic firm value, but outsiders can produce information about this value before bidding for shares. Inducing information production is beneficial for higher intrinsic value firms, because this information, reflected in secondary market prices, yields higher equity prices. We show that auctions and fixed-price offerings have different properties for inducing information production, solve for the equilibrium IPO mechanisms for firms with different characteristics, and explain the “IPO auction” puzzle.

We study the evolution of investment-banking relationships from 1933 to 2007. Relationship exclusivity and client concerns for the state of their banking relationships were strong through the first part of our sample period but then entered a period of sharp decline beginning around 1970. We interpret the bank-client relationship as an informal governance mechanism for curbing opportunistic behavior in a weak contracting environment and examine how technological change aggravated conflicts of interest within investment banks and between banks and their clients. This perspective sheds light on why trust between banks and their clients now appears to be in short supply.Received March 2, 2018; editorial decision June 11, 2018 by Editor Paolo Fulghieri.

Many institutions are attracted to diversified portfolios of hedge funds, referred to as Funds of Hedge Funds (FoHFs). In this article, we examine a new database that separates out for the first time the effects of diversification (the number of underlying hedge funds) from scale (the magnitude of assets under management). We find with others that the variance-reducing effects of diversification diminish once FoHFs hold more than 20 underlying hedge funds. This excess diversification actually increases their left-tail risk exposure once we account for return smoothing. Furthermore, the average FoHF in our sample is more exposed to left-tail risk than are naïve 1/N randomly chosen portfolios. This increase in tail risk is accompanied by lower returns, which we attribute to the cost of necessary due diligence that increases with the number of hedge funds.

We study bank policies to limit lending to companies engaged in mountaintop removal (MTR) coal mining, a form of coal extraction that has raised many environmental concerns. Using the staggered introduction of these policies, we document that these policies did not lead to meaningful changes in average bank lending or MTR mining. However, larger banks, banks that are under media pressure, and banks operating in the affected states are more likely to reduce MTR loans. Our results are consistent with the hypothesis that banks announced these policies under pressure and to improve their green credentials.
