CV Ingenuity (A): How to Evaluate the Commercial Viability of New Health Care Technologies
By: Regina E. Herzlinger and Andrew Otazo
Duke Rohlen (HBS MBA ’01) hoped to win over a prominent venture capital investor for Series B financing of his firm CVI that was creating a drug-eluting balloon (DES) to treat peripheral arterial disease. As a second-mover, Duke felt he was more likely to acquire... View Details

CV Ingenuity (B): Epilogue
By: Regina E. Herzlinger and Andrew Otazo
Duke Rohlen used a lea-nfunding, iconoclastic strategy for his start up for a drug eluding balloon for peripheral artery disease. His giant competitors were first movers. Did Duke obtain the funding he sought? How did his DEB fare versus that of his competitors?

Configurations of Extremal Type II Codes
By: Noam D. Elkies and Scott Duke Kominers
We prove configuration results for extremal Type II codes, analogous to the configuration results of Ozeki and of the second author for extremal Type II lattices. Specifically, we show that for n∈{8,24,32,48,56,72,96} every extremal Type II code of length n is... View Details

Multilateral Matching
By: John William Hatfield and Scott Duke Kominers
We introduce a matching model in which agents engage in joint ventures via multilateral contracts. This approach allows us to consider production complementarities previously outside the scope of matching theory. We show analogues of the first and second welfare... View Details

Strategy-Proofness, Investment Efficiency, and Marginal Returns: An Equivalence
By: John William Hatfield, Fuhito Kojima and Scott Duke Kominers
We show that a mechanism induces an agent to make efficient ex ante investment choices if and only if it rewards that agent with his marginal surplus; additionally, for an ex post efficient mechanism, these properties are equivalent to strategy-proofness for the agent.... View Details

Hidden Substitutes
By: John William Hatfield and Scott Duke Kominers
In this paper, we show that preferences exhibiting some forms of complementarity
in fact have an underlying substitutable structure. Specifically, we show that some
preferences that are not substitutable in the setting of many-to-one matching with
contracts become... View Details

Patent Trolls: Evidence from Targeted Firms
By: Lauren Cohen, Umit G. Gurun and Scott Duke Kominers
We provide the first large-sample evidence on the behavior and impact of non-practicing entities (NPEs) in the intellectual property space. We find that on average, NPEs appear to behave as opportunistic “patent trolls.” NPEs sue cash-rich firms—and target cash in... View Details

Convergence of Position Auctions under Myopic Best-Response Dynamics
By: Matthew Cary, Aparna Das, Benjamin Edelman, Ioannis Giotis, Kurtis Heimerl, Anna Karlin, Scott Duke Kominers, Claire Mathieu and Michael Schwarz
We study the dynamics of multi-round position auctions, considering both the case of exogenous click-through rates and the case in which click-through rates are determined by an endogenous consumer search process. In both contexts, we demonstrate that the dynamic... View Details

Patterns of Failure after Involved Field Radiation Therapy for Pediatric and Young Adult Hodgkin Lymphoma
By: Minh-Phuong Huynh-Le, Amanda J. Walker, Scott Duke Kominers, Ido Paz-Priel, Moody D. Wharam and Stephanie A. Terezakis
Involved field radiation therapy (IFRT) is integral in curative therapy for Hodgkin lymphoma (HL), although primarily used in patients with intermediate/high‐risk HL. We present failure patterns and clinical outcomes in a cohort of pediatric and young adult patients... View Details

Asymptotic Improvements of Lower Bounds for the Least Common Multiples of Arithmetic Progressions
By: Daniel M. Kane and Scott Duke Kominers
For relatively prime positive integers and r, we consider the least common multiple L_n:=\mathop{\textrm{lcm}}(u_0,u_1,\dots, u_n) of the finite arithmetic progression \{u_k:=u_0+kr\}_{k=0}^n. We derive new lower bounds on L_n that improve upon those obtained... View Details

Investment Incentives in Labor Market Matching
By: John William Hatfield, Fuhito Kojima and Scott Duke Kominers
We provide an illustration of how the design of labor market clearing mechanisms can affect incentives for human capital acquisition. Specifically, we extend the labor market matching model (with discrete transfers) of Kelso and Crawford (1982) to incorporate the... View Details

Delayed-Response Strategies in Repeated Games with Observation Lags
By: Drew Fudenberg, Yuhta Ishii and Scott Duke Kominers
We extend the folk theorem of repeated games to two settings in which players' information about others' play arrives with stochastic lags. In our first model, signals are almost-perfect if and when they do arrive, that is, each player either observes an almost-perfect... View Details

Progress Energy and Duke Energy (A)
By: Guhan Subramanian and Charlotte Krontiris
Just as Duke Energy and Progress Energy announce their merger—forming the largest utility company in the United States, to be led by the current Progress CEO—a nuclear reactor owned by Progress suffers major damage and must be taken offline. While Progress grapples... View Details

Minimal S-Universality Criteria May Vary in Size
By: Noam D. Elkies, Daniel M. Kane and Scott Duke Kominers
In this note, we give simple examples of sets $\mathcal{S}$ of quadratic forms that have minimal $\mathcal{S}$-universality criteria of multiple cardinalities. This answers a question of Kim, Kim, and Oh [KKO05] in the negative. View Details

Vacancies in Supply Chain Networks
By: John William Hatfield and Scott Duke Kominers
We use the supply chain matching framework to study the effects of firm exit. We show that the exit of an initial supplier or end consumer has monotonic effects on the welfare of initial suppliers and end consumers but may simultaneously have positive and negative... View Details

Kunshan, Incorporated: The Making of China's Richest Town
By: William C. Kirby, Nora Bynum, Tracy Yuen Manty and Erica M. Zendell
In 1980, the city of Kunshan was mere countryside, registering neither on the Chinese government's nor the international business community's radar. By 2010, Kunshan had become the richest city per capita in China and a global technology powerhouse, home to companies... View Details

On Derivatives Markets and Social Welfare: A Theory of Empty Voting and Hidden Ownership
By: Jordan M. Barry, John William Hatfield and Scott Duke Kominers
In the past twenty-five years, derivatives markets have grown exponentially. Large, modern derivatives markets increasingly enable investors to hold economic interests in corporations without owning voting rights, and vice versa. This leads to both empty... View Details

Stability and Competitive Equilibrium in Trading Networks
By: John William Hatfield, Scott Duke Kominers, Alexandru Nichifor, Michael Ostrovsky and Alexander Westkamp
We introduce a model in which agents in a network can trade via bilateral contracts. We find that when continuous transfers are allowed and utilities are quasi-linear, the full substitutability of preferences is sufficient to guarantee the existence of stable outcomes... View Details
