R&D Subsidies In Permissive And Restrictive Environment: Evidence From Korea, Yumi Koh, Gea M. Lee Jan 2023

R&D Subsidies In Permissive And Restrictive Environment: Evidence From Korea, Yumi Koh, Gea M. Lee

Research Collection School Of Economics

This paper investigates the extent to which a regulatory environment for R&D subsidies shapes the magnitude and direction of R&D subsidies set by a government and consequent innovation paths. When the WTO adopted a permissive regulatory environment, we find that the Korean government increased R&D subsidies significantly (89.21%) and selectively so for firms and industries with higher returns. Recipient firms conducted less basic research and more development research. Improvements in innovations were mostly incremental and minor. However, such changes did not persist once the WTO switched to a restrictive regulatory environment. Our findings show that the regulatory environment imposed by …

The Distributional Impacts Of Transportation Networks In China, Lin Ma, Tang Yang Dec 2022

The Distributional Impacts Of Transportation Networks In China, Lin Ma, Tang Yang

Research Collection School Of Economics

This paper evaluates the distributional impacts of transportation networks in China.We show that the quality of roads and railroads vary substantially over time and space, and ignoring these variations biases the estimates of travel time. To account for quality differences, we construct a new panel dataset and approximate quality using the design speed of roads and railroads that varies by vintage, class, and terrain at the pixel level. We then build a dynamic spatial general equilibrium model that allows for multiple modes and routes of transportation and forward-looking migration decision.We find aggregate welfare gain and less spatial income inequality led …

Organizations As Agents For Well-Being: How An Organizational Orientation To “Do Good” Could Lead To Flourishing, Andrew Frick Aug 2022

Organizations As Agents For Well-Being: How An Organizational Orientation To “Do Good” Could Lead To Flourishing, Andrew Frick

Master of Applied Positive Psychology (MAPP) Capstone Projects

It has been proposed that flourishing individuals enable flourishing organizations which leads to a flourishing world. However, is it also possible that by focusing on building a flourishing world a reciprocal elevation of organizational flourishing and individual flourishing can occur? This paper discusses well-being, the progression of research regarding organizational orientation to do good, and mirror flourishing. The amplification effect of virtuousness, along with the heliotropic effect, provide support to the theorized concept of mirror flourishing. In addition, this paper proposes a study design using appreciative inquiry to conduct interviews to better understand how an organization’s orientation to do good …


Selling Antitrust, Herbert J. Hovenkamp Aug 2022

Selling Antitrust, Herbert J. Hovenkamp

Faculty Scholarship at Penn Carey Law

Antitrust enforcers and its other defenders have never done a good job of selling their field to the public. That is not entirely their fault. Antitrust is inherently technical, and a less engaging discipline to most people than, say, civil rights or criminal law. The more serious problem is that when the general press does talk about antitrust policy it naturally gravitates toward the fringes, both the far right and the far left. Extreme rhetoric makes for better press than the day-to-day operations of a technical enterprise. The extremes are often stated in overdramatized black-and-white terms that avoid the real …


President Biden's Executive Order On Promoting Competition: An Antitrust Analysis, Herbert J. Hovenkamp Jul 2022

President Biden's Executive Order On Promoting Competition: An Antitrust Analysis, Herbert J. Hovenkamp

Faculty Scholarship at Penn Carey Law

In July, 2021, President Biden signed a far ranging Executive Order directed to promoting competition in the American economy. This paper analyzes issues covered by the Order that are most likely to affect the scope and enforcement of antitrust law. The only passage that the Executive Order quoted from a Supreme Court antitrust decision captures its antitrust ideology well – that the Sherman Act:

rests on the premise that the unrestrained interaction of competitive forces will yield the best allocation of our economic resources, the lowest prices, the highest quality and the greatest material progress, while at the same time …


Essays On Industrial Organization And Health Economics, Cecilia S. Diaz Campo Jul 2022

Essays On Industrial Organization And Health Economics, Cecilia S. Diaz Campo

Electronic Thesis and Dissertation Repository

My thesis consists of three chapters studying the impact of health insurance design and public health policy on consumers’ health and health care utilization, welfare, and costs.

Chapter 2 studies an overlooked dynamic incentive that encourages health care utilization, which I term \textit{dynamic moral hazard}. Typical health plans feature high deductibles and caps on consumers' out-of-pocket spending, which generate nonlinear pricing. These nonlinearities, coupled with the uncertainty intrinsic to future health care demand, encourage consumers to increase spending since current utilization lowers future expected prices. Standard models study health care utilization decisions through the lens of annual models, which abstract …


Too Much Of A Good Thing? A Governing Knowledge Commons Review Of Abundance In Context, Michael J. Madison, Brett M. Frischmann, Madelyn Sanfilippo, Katherine J. Strandburg Jul 2022

Too Much Of A Good Thing? A Governing Knowledge Commons Review Of Abundance In Context, Michael J. Madison, Brett M. Frischmann, Madelyn Sanfilippo, Katherine J. Strandburg

Articles

The economics of abundance, along with the sociology of abundance, the law of abundance, and so forth, should be re-framed, linked, and situated in a common context for empirical rather than conceptual research. Abundance may seem to be a new, big thing, between anxiety over information overload, Big Data, and related technological disruptions. But scholars know that abundance is an ancient phenomenon, which only seemed to disappear as twentieth century social science focused on scarcity instead. Restoring the study of abundance, and figuring out how to solve the problems that abundance might create, means shedding disciplinary blinders and going back …

Three Essays On Public Policy And Welfare In Developing Countries, Alvaro Jeronimo Callejas Jun 2022

Three Essays On Public Policy And Welfare In Developing Countries, Alvaro Jeronimo Callejas

Doctoral Dissertations

Developing countries typically implement public policies that modify the market structure to reach a specific goal. However, in this attempt to achieve a policy objective, policymakers may not consider unintended consequences caused by firms' and consumers' optimizing behavior. Moreover, the reaction of market agents to the implemented policy may undermind its effectiveness or lead to an outcome opposite to the one persuaded. This dissertation uses a set of structural models to assess the welfare effect of both intended and unintended consequences of public policies introduced in developing countries.

In the first chapter, we evaluate the welfare implications of a public …


Antitrust Liability For False Advertising: A Response To Carrier & Tushnet, Susannah Gagnon, Herbert J. Hovenkamp Jun 2022

Antitrust Liability For False Advertising: A Response To Carrier & Tushnet, Susannah Gagnon, Herbert J. Hovenkamp

Faculty Scholarship at Penn Carey Law

This reply briefly considers when false advertising can give rise to antitrust liability. The biggest difference between tort and antitrust liability is that the latter requires harm to the market, which is critically dependent on actual consumer response. As a result, the biggest hurdle a private plaintiff faces in turning an act of false advertising into an antitrust offense is proof of causation – to what extent can a decline in purchase volume or other market rejection be specifically attributed to the defendant’s false claims? That requirement dooms the great majority of false advertising claims attacked as violations of the …


The Slogans And Goals Of Antitrust Law, Herbert J. Hovenkamp Jun 2022

The Slogans And Goals Of Antitrust Law, Herbert J. Hovenkamp

Faculty Scholarship at Penn Carey Law

This is a comparative examination of the slogans and goals most advocated for antitrust law today – namely, that antitrust should be concerned with “bigness,” that it should intervene when actions undermine the “competitive process,” or that it should be concerned about promoting some conception of welfare. “Bigness” as an antitrust concern targets firms based on absolute size rather than share of a market, as antitrust traditionally has done. The bigness approach entails that antitrust cannot be concerned about low prices, or the welfare of consumers and labor. Nondominant firms could not sustain very high prices or cause significant reductions …


The Role Of Data For Ai Startup Growth, James Bessen, Stephen Michael Impink, Lydia Reichensperger, Robert Seamans Jun 2022

The Role Of Data For Ai Startup Growth, James Bessen, Stephen Michael Impink, Lydia Reichensperger, Robert Seamans

Faculty Scholarship

Artificial intelligence (“AI”)-enabled products are expected to drive economic growth. Training data are important for firms developing AI-enabled products; without training data, firms cannot develop or refine their algorithms. This is particularly the case for AI startups developing new algorithms and products. However, there is no consensus in the literature on which aspects of training data are most important. Using unique survey data of AI startups, we find that startups with access to proprietary training data are more likely to acquire venture capital funding.

Studies of blockchain governance can be divided into analyses of the governance of blockchains (such as rules and power dynamics within a given network) and governance by blockchains (such as how blockchains can be implemented to improve self-governance of community-based peer production networks). Less emphasis has been placed on applications of distributed ledgers to public sector governance. Our review clarifies that the decentralization and distributive features that enable blockchains to link up loosely connected private organizations and public agencies to improve efficiency and transparency of government transactions. However, most blockchain applications lack clear advantages over the conventional digital recording of …

Strengthening The Southern Nevada Workforce Pipeline, Katie M. Gilbertson May 2022

Strengthening The Southern Nevada Workforce Pipeline, Katie M. Gilbertson

Student Papers / Brookings Minor Culminating Projects

Workforce development has been a keystone in the discussion of economic diversification of Las Vegas for decades. The leisure and hospitality industry is the lifeline for the Southern Nevada economy due to the reliance on tourism as the city’s main economic driver. The leisure and hospitality industry requires physical labor and more face-to-face customer interaction than other employment sectors. Thus, these jobs often do not require high educational attainment, but rather sharp soft skills like effective listening, nonverbal communication, and negotiation strategies. While these are valuable traits, the lack of educational attainment within the leisure and hospitality workforce suppresses employees’ …

Understanding sources leading to a lower accessibility of financial services is integral for an effective endeavor to lower barriers to financial services with far-reaching policy and economic implications. The economic literature provides evidence of the beneficial effects of increased access to financial services as well as the adverse effects of diminished …


Essays On The Economics Of Electric Vehicle Charging Stations, Aspen Underwood May 2022

Essays On The Economics Of Electric Vehicle Charging Stations, Aspen Underwood

All Dissertations

Electric vehicles (EVs) have peaked people’s interest since the first electric-powered vehicle was developed in the 1830’s. By the 1890’s EVs were the most common vehicle in the U.S. However, due to issues with charging batteries and limitations of the electrical grid, EVs were left behind as gasoline vehicles became commonly available in the early 20th century. Several attempts to repopularize EVs over the last 100 years suffered from difficulties with limited driving ranges, but today, expanded driving ranges and improved charging capabilities have made EVs a real alternative to gasoline engines. The possibility of zero-emission transportation made possible by …
