Bridging Quasi-Experimental and Structural Approaches for Robust Evaluation of US Airline Mergers
Gaurab Aryal, Anirban Chattopadhyaya, Federico Ciliberto
We bridge quasi-experimental and structural approaches for robust merger evaluation. First, we show that the difference-in-differences (DiD) equation is the "reduced form" of a str…
Econometrics of Insurance with Multidimensional Types
Gaurab Aryal, Isabelle Perrigne, Quang Vuong +1
In this paper, we address the identification and estimation of insurance models where insurees have private information about their risk and risk aversion. The model includes rando…
The Benefits from Bundling Demand in K-12 Broadband Procurement
Gaurab Aryal, Charles Murry, Pallavi Pal +1
We study a new market design for K-12 school broadband procurement that switched from school-specific bidding to a system that bundled schools into groups. Using an event study app…
Common Subcontracting and Airline Prices
Gaurab Aryal, Dennis J. Campbell, Federico Ciliberto +1
In the US airline industry, independent regional airlines fly passengers on behalf of several national airlines across different markets, giving rise to $\textit{common subcontract…
Valuing Pharmaceutical Drug Innovations
Gaurab Aryal, Federico Ciliberto, Leland E. Farmer +1
We propose a methodology to estimate the market value of pharmaceutical drugs. Our approach combines the event study method with a discounted cash flow model that infers drug value…
Security Issuance, Institutional Investors and Quid Pro Quo
Gaurab Aryal, Zhaohui Chen, Yuchi Yao +1
Securities issuance through intermediaries is subject to agency problems and informational frictions. We examine these effects using SPAC data. We identify ``premium'' investors wh…
Desirable Rankings
Gaurab Aryal, Thayer Morrill, Peter Troyan
We study the problem of aggregating individual preferences over alternatives into a collective ranking. A distinctive feature of our setting is that agents are matched to alternati…
Procurements with Bidder Asymmetry in Cost and Risk-Aversion
Gaurab Aryal, Hanna Charankevich, Seungwon Jeong +1
We propose an empirical method to analyze data from first-price procurements where bidders are asymmetric in their risk-aversion (CRRA) coefficients and distributions of private co…
Empirical Framework for Cournot Oligopoly with Private Information
Gaurab Aryal, Federico Zincenko
We propose an empirical framework for asymmetric Cournot oligopoly with private information about variable costs. First, considering a linear demand for a homogenous product with a…
Signaling and Employer Learning with Instruments
Gaurab Aryal, Manudeep Bhuller, Fabian Lange
This paper considers the use of instruments to identify and estimate private and social returns to education within a model of employer learning. What an instrument identifies depe…
Price Discrimination in International Airline Markets
Gaurab Aryal, Charles Murry, Jonathan W. Williams
We develop a model of inter-temporal and intra-temporal price discrimination by monopoly airlines to study the ability of different discriminatory pricing mechanisms to increase ef…
Coordinated Capacity Reductions and Public Communication in the Airline Industry
Gaurab Aryal, Federico Ciliberto, Benjamin T. Leyden
We investigate the allegation that legacy U.S. airlines communicated via earnings calls to coordinate with other legacy airlines in offering fewer seats on competitive routes. To t…
Auctioning Annuities
Gaurab Aryal, Eduardo Fajnzylber, Maria F. Gabrielli +1
We propose and estimate a model of demand and supply of annuities. To this end, we use rich data from Chile, where annuities are bought and sold in a private market via a two-stage…
Is Collusion-Proof Procurement Expensive?
Gaurab Aryal, Maria F. Gabrielli
Collusion among bidders adversely affects procurement cost and in some cases efficiency, and it seems collusion is more prevalent that we would like. Statistical methods of detecti…
Identification of Insurance Models with Multidimensional Screening
Gaurab Aryal, Isabelle Perrigne, Quang Vuong
This paper addresses the identification of insurance models with multidimensional screening where insurees have private information about their risk and risk aversion. The model in…
Empirical Relevance of Ambiguity in First Price Auction Models
Gaurab Aryal, Dong-Hyuk Kim
We study the identification and estimation of first-price auction models where bidders have ambiguity about the valuation distribution and their preferences are represented by maxm…
Identification and Estimation of Multidimensional Screening
Gaurab Aryal, Federico Zincenko
We study the identification and estimation of a multidimensional screening model in which a monopolist sells a product with multiple continuous attributes to consumers with private…
A Note on Kuhn's Theorem with Ambiguity Averse Players
Gaurab Aryal, Ronald Stauber
Kuhn's Theorem shows that extensive games with perfect recall can equivalently be analyzed using mixed or behavioral strategies, as long as players are expected utility maximizers.…
Semiparametric Estimation of First-Price Auction Models
Gaurab Aryal, Maria Florencia Gabrielli, Quang Vuong
We propose a semiparametric method to estimate the density of private values in first-price auctions. Specifically, we model private values through a set of conditional moment rest…
