Two‐Sided Matching: How Corporate Issuers and Their Underwriters Choose Each Other

In this article, the authors update and confirm the findings of a 2005 article that was the first to view corporate underwriter choices as the outcome of a two‐sided matching process in which issuers look to the abilities of the underwriters offering their services and underwriters focus on the quality of the issuers that wish to use their services. This view offers a contrast with both the conventional representation of issuer‐underwriter associations as one‐sided decisions (by either issuers or underwriters) and the classical economist's representation of a competitive market in which prices serve as the primary market‐clearing mechanism. In their examination of both initial public offerings (IPOs) and seasoned equity offerings (SEOs) during the period 1980–2010, the authors continue to find strong evidence that higher‐quality issuers associate with more reputable underwriters and lower‐quality issuers match with lower reputation underwriters. Moreover, when examining cases of underwriter switching between an IPO and SEOs by the same issuer, they find that cases involving the largest divergence in the relative rankings of issuer and underwriter were the most likely to produce a change of underwriter—and that issuers that experienced larger post‐ IPO increases in quality were more likely to find more reputable underwriters for their SEOs (than for their IPOs). The authors also find that the larger the number of offerings brought to market in a given year, the smaller the market share of the top‐tier underwriters, likely reflecting the willingness of the most reputable underwriters to turn down business to maintain quality and reputation. Finally, the most reputable underwriters appear to benefit from the fact that the issuers whose IPOs they underwrite end up raising larger amounts of capital, both at the time of the IPO and in the larger and more frequent seasoned offerings by such issuers that come after the IPO. This evidence in support of two‐sided matching suggests that, especially for high‐quality issuers, the reputation of the underwriters they contract with for security offerings is likely to be more important than the underwriting fees they incur. What's more, the authors' finding that the most reputable underwriters are less likely to lose high‐quality clients and have more stable market share—and that the higher‐quality issuers they attract end up raising larger amounts of capital over their lives as public companies—suggests that underwriters' investments in building and preserving their reputations have a large expected payoff.     

Solving the Winner Determination Problem in a Divisible-Object Auction

In an auction of a divisible object, bidders' demand functions are often assumed to be nonincreasing, meaning that bidders are willing to pay less or the same price for every additional unit. Under this assumption, the optimal allocation that maximizes the auctioneer's revenue can be found using a greedy-based procedure. This article argues that situations may arise where a bidder may need to express her preferences through a nondecreasing demand function; when such a bidder is present in the auction, the greedy-based procedure does not guarantee the optimal allocation. Thus, this article proposes a mixed integer program that finds the optimal allocation in a divisible-object auction at which bidders submit their bids as arbitrary stepwise demand functions. The practical aspect of the mathematical program is presented by means of a simple yet illustrative example in a treasury bond auction setting. The results of the auctioneer's revenue are reported as a function of the number of bidders with nonincreasing and nondecreasing demand functions.     

Copula‐Based Formulas to Estimate Unexpected Credit Losses (The Future of Basel Accords?)

The model used to estimate the capital required to cover unexpected credit losses in financial institutions (Basel II) has some drawbacks that reduce its ability to capture potential joint extreme losses in downturns. This paper suggests an alternative approach based on Copula Theory to overcome such flaws. Similarly to Basel II, the suggested model assumes that defaults are driven by a latent variable which varies as a response to an unobserved factor. On the other hand, the use of copulas allows the identification of asymmetric dependence between defaults which has been registered in the literature. As an example, a specific copula family (Clayton) is adopted to represent the association between the latent variables and a formula to estimate potential unexpected losses at a certain level of confidence is derived. Simulations reveal that, in most of the cases, the alternative model outperforms Basel II for portfolios with right‐tail‐dependent probabilities of default (supposedly, a good representation for real loan portfolios).     

Access pricing and investment: a real options approach

This paper examines a three-period model of an investment decision in a network industry characterized by demand uncertainty, economies of scale and sunk costs. In the absence of regulation we identify the market conditions under which a monopolist decides to invest early as well as the overall welfare generated by this decision. In a regulated environment, we consider a vertically integrated network provider that is required to provide access to downstream competitors and compare two distinct access pricing methodologies: the Efficient Component Pricing Rule (ECPR) and the Option to Delay Pricing Rule (ODPR). We identify the welfare-maximizing access prices using the unregulated market output as a benchmark and show that optimal access regulation depends on market conditions (that is, the nature of demand) with two possible outcomes: (i) access prices that provide a positive payoff to the incumbent, that is, provide a positive compensation to account for the option to delay; and (ii) access prices that yield a zero payoff to the incumbent. Moreover, unlike the earlier literature that argues in favor of an ECPR-type methodology to account for the interaction between irreversibility and demand uncertainty, we find that, except under very specific conditions, an access price that accounts for the option to delay value is welfare-superior to the ECPR.      

Common liquidity shocks and market collapse: Lessons from the market for perps

We show how a high degree of commonality in investor liquidity shocks can diminish incentives for intermediaries to keep markets open and lead to market collapse, even without information asymmetry or news affecting fundamentals. We motivate our model using the perpetual floating-rate note market where two years of explosive growth – in which issues by high quality borrowers were placed with institutional investors and traded in a liquid secondary market – were followed by a precipitous collapse when market intermediaries withdrew due to large order imbalances. We shed new light on the trade-off between ownership concentration and market liquidity.     

Analytic Pricing of Employee Stock Options

We introduce a model that captures the main properties thatcharacterize employee stock options (ESO). We discuss the likelihoodof early voluntary ESO exercise, and the obligation to exerciseimmediately if the employee leaves the firm, except if thishappens before options are vested, in which case the optionsare forfeited. We derive an analytic formula for the price ofthe ESO and in a case study compare it to alternative methods.     

Designing minimum-cost recycling collection networks with required throughput

The problem of designing minimum-cost recycling networks with required throughput is a subset of the broader class of facility location problems in which the recycler wishes to determine the optimal number and location of receiving centers as well as the correct financial incentive to be offered in order to stimulate collection of used or unrecoverable products to a degree required for regulatory reasons or otherwise. This paper presents a conceptual framework, an analytical model, and a three-stage algorithmic solution for this problem. An illustrative case study in the recycling of unrecoverable tires in southern states of Brazil is presented.     

Growth Due To Globalization*

This article presents a growth model including geographical space and transportation costs in which the geographical area where firms sell their product is endogenous. Growth is generated by the expansion of trade and there is a positive relationship between degree of openness and income level. The model explains why economies become increasingly more open and why the degree of openness is not robustly correlated with growth. In contrast to other growth models, investment in transport infrastructure plays an important role and the size of the country does not affect growth.
