Pereira Joana, Tavalaei M. Mahdi, Özalp Hakan (2019) Blockchain-based platforms: decentralized infrastructures and its boundary conditions, Technological Forecasting & Social Change 146 pp. 94-102 Elsevier
Blockchain technology has been receiving much public attention recently, promising to disintermediate transactions through a decentralized governance and a distributed data-infrastructure. However, the majority of the previous studies have focused on the technical aspects, and overlooked blockchain investigation from a managerial perspective. In this paper, based on platform-ecosystem, transaction cost economics, and open-source literature, we contrast and compare blockchain-based platforms and centralized platforms; in other words, decentralized versus centralized governance of the platform. We base our conceptual analysis on three dimensions?transaction cost, cost of technology, and community involvement?, exploring the conditions under which blockchain-based platforms are more advantageous than centralized platforms. We, first, compare gains from lower opportunism and uncertainty thanks to protocols and smart contracts in blockchain technology versus costs of higher coordination and complexity of (re)writing those contracts. Second, we compare gains from immutability and transparency in blockchain-based platforms versus the technological cost of verification and distributed ledger infrastructure. Finally, we compare intrinsic and extrinsic motivations of community around centralized and blockchain-based platforms to participate and different mechanism involved, i.e. pricing mechanism in the former and crypto-incentives in the latter.
Tavalaei M. Mahdi, Santalo Juan (2019) Pure versus hybrid competitive strategies in the airport industry, Transportation Research Part A: Policy and Practice 124 pp. 444-455 Elsevier
The advent of low-cost carriers has dramatically changed the competitive landscape of the airport industry and diminished the monopoly power that airports once enjoyed. Today, major airports compete directly with periphery airports, which are becoming the apparent choice of low-cost carriers. In fact, contracting with low-cost airlines has become a determinant factor in airport strategies, and airports now face a strategic decision to position themselves towards either low-cost or full-service (legacy) airline, or both. This paper examines the impact of these competitive strategies on airport financial performance. Building on the strategic purity premise, we hypothesise that being either a low-cost-oriented or legacy-oriented airport (pursuing a pure strategy) is associated with superior financial performance, in comparison with combining the two (a hybrid strategy). Moreover, the benefit of pure strategies increases with the intensity of competition among nearby airports. The paper supports these hypotheses with findings drawn from the U.S. airport industry.
