The Sharing Economy: Disrupting the Business and Legal Landscape
THE SHARING ECONOMY: DISRUPTING THE BUSINESS AND LEGAL LANDSCAPE Panel 402 NAPABA Annual Conference Saturday, November 5, 2016 9:15 a.m. 1. Program Description Tech companies are revolutionizing the economy by creating marketplaces that connect individuals who “share” their services with consumers who want those services. This “sharing economy” is changing the way Americans rent housing (Airbnb), commute (Lyft, Uber), and contract for personal services (Thumbtack, Taskrabbit). For every billion-dollar unicorn, there are hundreds more startups hoping to become the “next big thing,” and APAs play a prominent role in this tech boom. As sharing economy companies disrupt traditional businesses, however, they face increasing regulatory and litigation challenges. Should on-demand workers be classified as independent contractors or employees? Should older regulations (e.g., rental laws, taxi ordinances) be applied to new technologies? What consumer and privacy protections can users expect with individuals offering their own services? Join us for a lively panel discussion with in-house counsel and law firm attorneys from the tech sector. 2. Panelists Albert Giang Shareholder, Caldwell Leslie & Proctor, PC Albert Giang is a Shareholder at the litigation boutique Caldwell Leslie & Proctor. His practice focuses on technology companies and startups, from advising clients on cutting-edge regulatory issues to defending them in class actions and complex commercial disputes. He is the rare litigator with in-house counsel experience: he has served two secondments with the in-house legal department at Lyft, the groundbreaking peer-to-peer ridesharing company, where he advised on a broad range of regulatory, compliance, and litigation issues. Albert also specializes in appellate litigation, having represented clients in numerous cases in the United States Supreme Court, the United States Court of Appeals for the Ninth Circuit, and California appellate courts. -
R&D and the Market for Acquisitions
R&D and the Market for Acquisitions Gordon PhillipsW and Alexei Zhdanov** COMMENTS WELCOME: First version January 10, 2010. This Version: February 20, 2011 We provide a new theory and empirical tests showing how an active acquisition market posi- tively aects rm incentives to innovate and conduct R&D. Our model shows how the incentives of small rms to conduct R&D in order to innovate increase with competition, demand and the probability that they are taken over. In contrast, we show that large rms optimally may decide to purchase smaller innovative rms and conduct less R&D themselves. Empirically, we document that the R&D of small rms responds more than the R&D of larger rms to demand shocks and the probability of being an acquisition target. The results also show that rm R&D increases with product-market competition and with industry acquisition liquidity and that these eects are stronger for smaller rms.

We would like to thank Denis Gromb, Urs Peyer and seminar participants at Insead for helpful comments and discussion.

A Study of the Soc and Smartphone Industries
Vertical Structure and Innovation: A Study of the SoC and Smartphone Industries Chenyu Yang∗ Department of Economics, University of Maryland, College Park December 19, 2019 Abstract This article studies how vertical integration and upstream R&D subsidy affect innovation and welfare in vertically separated industries. I formulate a dynamic structural model of a dominant upstream firm and oligopolistic downstream firms that invest in complementary innovations. I estimate the model using data on the System-on-Chip (SoC) and smartphone industries. The results suggest that a vertical merger can increase innovation and welfare, mainly driven by the investment coordination of the merged firms. I also find that subsidizing the upstream innovation increases overall private investment, innovation and welfare. 1 Introduction In vertical industries, upstream and downstream innovations are often complementary. Upstream firms upgrade the core technology essential to performance enhancement, and downstream firms combine the technology with innovative designs in new consumer products. Examples of com- plementary innovations include traction batteries (upstream) and electric vehicles (downstream), CPUs (upstream) and personal computers (downstream) and System-on-Chips (SoCs, upstream) ∗Department of Economics, University of Maryland, College Park; [email protected].

I am grateful for the guidance and support from my advisers Jeremy Fox, Daniel Ackerberg, Ying Fan and Srinivasaraghavan Sriram.

Dr. Ishaq Unwala 11400 Rockwell Pl Phone #: (512) 567 - 4467 Austin, TX 78726 [email protected] WORK EXPERIENCE University of Houston Clear Lake, Houston, TX Aug '14 - present Assistant Professor of Computer Engineering Teaching graduate level classes in Computer Engineering. Areas of interest Design, Test and Verification of digital designs. Oracle Corporation, Austin, TX Senior Hardware Engineer Sep '10 - Jan '14 Recently employed at Oracle Corporation in Computer and Microelectronic Technology (CMT) division, formerly Sun Microsystems. The CMT division designs, develops and implements complete SPARC systems, including SPARC Core, SOC for SPARC Core, and Solaris Operating System. I was responsible for functional verification of the SPARC Core. I have worked on two SPARC processor cores, Tahoe (S4) and Siete (S5). Functional verification includes many sub-tasks, including working with logic design team on design specification documents, Test Generation, Test Environment design and development, Functional Coverage specification and implementation, root causing Test failures, Formal verification, use and design of many other Design Tools. - Project : Siete (S5) CPU (2013-2014) Most recently I worked on design verification of the Load Store Unit for a new SPARC processor. I proposed, specified, and implemented a new test generator for testing of the Load Store unit (LSU) for the SPARC Core. The new test generator provided hundreds of tests that otherwise would have to be hand written. I wrote testing and coverage specification for LSU blocks. Design and verification work is still in progress. Siete is projected to tape-out in March 2015. - Project : Tahoe (S4) CPU (2010-2013) I specified, designed and implemented the unit test environment (UTE) for the Instruction Fetch Unit (IFU) design for Tahoe. -
