In recent decades, Sub-Saharan Africa (SSA) has experienced rapid advances in digitalization, with unprecedented growth in internet penetration. This paper investigates the impact of internet penetration in SSA on real GDP growth, productivity, and sector output and employment. The analysis...

Demands for high performance electrical power transmission cables continues to rise, especially for offshore power transmission, electric vehicles, portable electronics, and deployable military applications. Carbon nanotube (CNT)-Copper (Cu) core-shell wire is regarded as one of the best...

It is well-known that the Court of Justice of the European Union (CJEU) has played a key role in giving the EU acquis in the area of intellectual property law the relevance it has today. Especially the series of judgments clarifying the broad notion of “communication to the public” as laid...

In this paper, the study of Single Mode Fiber (SMF) and Bidirectional Fiber cables is done in optical communication system. The source used for the system is (CW) Laser and at the reception PIN diode is used. The distance between the transmitter and the receiver is 10.5 km and 110 km for SMF and...

COVID-19 vaccines have already reduced infections and hospitalizations across the globe, yet resistance to vaccination remains strong. This paper investigates the role of cable television news in vaccine skepticism and associated local vaccination rates in the United States. We find that, in the...

Patent pools are increasingly well known as a mechanism to license patents essential to a technical standard. CableLabs had early experience when it launched in the mid-1990s the first modern day pool covering MPEG2-essential video codec patents. Recently, the fractured licensing environment for...

This paper examines the introduction of Direct Broadcast Satellites as an alternative to cable television and the welfare gains such satellites generated for consumers. The extent to which satellites compete with cable has become an important issue in the debate over re-regulation of cable...

Media outlets often present diverging, even conflicting, perspectives on reality — not only informing, but potentially misinforming audiences. We study the extent to which misinformation broadcast on mass media at the early stages of the coronavirus pandemic influenced health outcomes. We...

Power cable engineering is a critical method for urban power supply, and ductbank laying of cables is a way of underground cable lines. Considering the cost and construction, MPP pipes with poor heat dissipation performance are often used in ductbank. Many cables are arranged densely in the...

Partisan cable news broadcasts have a causal effect on the size and composition of budgets in U.S. localities. Utilizing channel positioning as an instrument for viewership, we show that exposure to the conservative Fox News Channel shrinks local government budgets, while liberal MSNBC enlarges...

As the cable system accomplishing 100% digitalization in Taiwan, NCC (National Communications Commission) proposes an unbundled pricing mechanism to allow consumers to choose the cable television channels that they actually watch. This study conducted an online survey and 1358 effective...

This report examines the competitive effects of Hybrid Mobile Network Operators (HMNOs) — mobile virtual network operators that rely in large part on self-deployed facilities — on the market for mobile wireless services and recommends that the Federal Communications Commission (FCC) broaden...

We measure the welfare distortions from endogenous quality choice in imperfectly competitive markets. For U.S. cable-television markets between 1997-2006, prices are 33% to 74% higher and qualities 23% to 55% higher than socially optimal. Such quality overprovision contradicts classic results in...

This paper studies the effects of areal cable cars on mode of transport, time use and employment in the metropolitan area of La Paz, Bolivia. Using an instrumental variables approach, we estimate local average treatment effects of cable car use for residents who use the system due to proximity...

Since the emergence of partisan cable news networks (CNN, Fox News, and MSNBC) in the mid-1990s, the way many Americans get their political information has changed. Previous research has examined the associations between cable news viewership and individuals' political knowledge, attitudes, and...

Between 2005 and 2008, 19 of the 50 states of the U.S. reformed the franchising process for cable television, significantly easing entry into local markets. Using a difference-in-differences approach that exploits the staggered introduction of reforms, we find that prices for “Basic” service...

In this paper we study how the coexistence of access regulations for legacy (copper) and fiber networks shapes the incentives to invest in network infrastructure. To this end, we develop a theoretical model explaining investment incentives by incumbent telecom operators and heterogeneous...

We exploit supply-driven heterogeneity in the expansion of cable television across Norwegian municipalities to identify developmental effects of commercial television exposure during childhood. We find that higher exposure to commercial television reduces cognitive ability and high school...

The never ending story of the abuse of cable market power in the multichannel video programming distribution (MVPD) and the broadband Internet access service (BIAS) markets involves the central themes of communications policy over the past fifty years. Public policy must create the conditions...

Local television stations are platforms in a two-sided market connecting advertisers and viewers. This paper explicitly examines the effect that important intermediaries (such as cable, telephone, and satellite distributors) may have on a platform's pricing behavior in a two-sided market. I find...

We measure the welfare consequences of endogenous quality choice in imperfectly competitive markets. We introduce the concept of a "quality markup" and measure the relative welfare consequences of market power over price and quality. For U.S. paid-television markets during 1997-2006, we find...

We measure the welfare consequences of endogenous quality choice in imperfectly competitive markets. We introduce the concept of a "quality markup" and measure the relative importance for welfare of market power over price versus market power over quality. For U.S. cable-television markets...

This paper is one of the major economic studies I submitted to the FCC in opposition to the proposed merger of Comcast and Time Warner Cable. After reviewing and rebutting some of the economic theories and evidence put forth by Comcast in support of the merger the paper presents an antitrust...

The paper examines an array of issues regarding the development of standard through both consensus and non-consensus processes. Key areas of inquiry included the growing importance of market-driven consortia (MDCs), potential benefits and problems from use of non-consensus processes, ANSI's...

We measure the persuasive effects of slanted news and tastes for like-minded news, exploiting cable channel positions as exogenous shifters of cable news viewership. Channel positions do not correlate with demographics that predict viewership and voting, nor with local satellite viewership. We...

This study analyzes the extent to which Federal Universal Service Fund subsidies are paid to rural telephone companies to provide service in areas served by unsubsidized competitors, i.e., cable TV companies that now provide both broadband and cable telephony service. The evidence shows that...
