Oxford Research Proposal Example: Airport operations manager to aviation policy (Score 93)

Airport slot allocation sits at the intersection of competition law, economic regulation, and operational safety governance — yet the legal framework governing it in the United Kingdom has received comparatively little systematic scrutiny since the country's departure from the European Union's slot coordination regime. Under EU Regulation 95/93, slot allocation at coordinated airports followed a centralised, grandfather-rights model overseen by Network Manager. Post-Brexit, the UK retained the substantive structure of that regulation through the Air Traffic Management (Amendment etc.) (EU Exit) Regulations 2020, but without the institutional architecture — the Network Manager, the Performance Review Body, or the Single European Sky oversight mechanism — that gave the original rules their enforcement coherence. This proposal asks: to what extent does the current UK slot allocation framework create compliance gaps that distort capacity use at Level 3 coordinated airports, and what regulatory design changes would reduce those distortions without undermining incumbent carrier interests or slot mobility? Two subsidiary questions follow. First, do the existing use-it-or-lose-it thresholds (80/20 rule) generate perverse incentives — specifically, ghost flights or artificial slot fragmentation — that the post-Brexit enforcement architecture is structurally unable to detect? Second, does the Civil Aviation Authority's current mandate provide sufficient legal basis for proactive compliance monitoring, or does it require primary legislative amendment? These questions are tractable within a one-year MSc research project. They are grounded in a bounded statutory corpus, a finite set of coordinated UK airports, and publicly available slot utilisation data published by Airport Coordination Limited (ACL). The policy stakes are concrete: slot scarcity at Heathrow, Gatwick, and Manchester directly affects route competition, regional connectivity, and the UK's ability to negotiate air services agreements post-Brexit. Two bodies of scholarship are relevant, and neither fully addresses the post-Brexit enforcement problem. The first is the economics of airport slot markets. Scholars working in this tradition — including work associated with the Airports Commission evidence base and academic contributions from transport economics — have analysed slot trading, secondary markets, and the welfare effects of grandfather rights. This literature is sophisticated on allocative efficiency but treats legal enforceability as exogenous: it assumes that whatever rule exists will be applied consistently, which is precisely what the post-Brexit institutional gap calls into question. The second body of literature concerns regulatory design in network industries. Scholars in this tradition have examined how enforcement capacity, information asymmetries, and institutional fragmentation affect compliance behaviour in sectors including energy, telecommunications, and rail. The application of this framework to aviation slot regulation in a post-Brexit UK context is underdeveloped. Most comparative regulatory work on aviation continues to treat the EU as the relevant unit of analysis, leaving the UK's divergent trajectory underexamined. The gap this proposal addresses is therefore specific: there is no published study that applies a regulatory design lens to the post-Brexit UK slot coordination framework, tests whether the current CAA mandate is legally sufficient for proactive enforcement, and connects that legal analysis to observable slot utilisation patterns. Filling this gap requires combining statutory interpretation, regulatory theory, and quantitative analysis of slot data — a combination that neither the economics literature nor the regulatory law literature has yet attempted for this jurisdiction and this period. The proposal uses a two-phase sequential design. Phase one is doctrinal and comparative legal analysis. I will map the statutory and regulatory instruments governing slot coordination in the UK — principally the retained EU regulation, the Civil Aviation Act 1982 as amended, and the CAA's published enforcement guidance — against the institutional architecture they presuppose. I will then compare this with the enforcement mechanisms available under the original EU regime and with the slot coordination frameworks of two non-EU comparators (the United States FAA High Density Rule airports and Australia's Sydney Airport Demand Management Act) to identify structural differences in enforcement capacity. This phase produces a typology of compliance gap types: detection gaps, attribution gaps, and sanction gaps. Phase two is quantitative analysis of slot utilisation data. ACL publishes season-level slot utilisation reports for UK coordinated airports. I will construct a dataset covering the 2018–19 pre-Brexit baseline through the 2023–24 season, disaggregated by airport and carrier category (legacy, low-cost, regional). Using descriptive statistics and, where the data support it, a difference-in-differences specification comparing utilisation patterns before and after the Brexit transition period, I will test whether utilisation rates and slot return behaviour changed in ways consistent with reduced enforcement credibility. The identification assumption — that pre-Brexit trends would have continued absent the institutional change — is imperfect, given the confounding effect of COVID-19 on 2020–22 data. I will address this by restricting the primary comparison to 2018–19 versus 2023–24 and treating the intervening years as a robustness check rather than a primary identification window. The doctrinal findings from phase one will frame the interpretation of the quantitative patterns in phase two. The proposal does not claim causal identification in the econometric sense; it claims that the combination of legal analysis and utilisation evidence can support a defensible regulatory diagnosis. The primary data sources — ACL utilisation reports, CAA published decisions, Hansard records of relevant parliamentary scrutiny, and the statutory instruments themselves — are publicly available. No access permissions, fieldwork approvals, or institutional data-sharing agreements are required for the core analysis. If I pursue supplementary elite interviews with slot coordinators or CAA officials, I will apply for ethical approval through the relevant Oxford research ethics process in advance; this strand is treated as supplementary rather than load-bearing. The main feasibility risk is data granularity. ACL publishes aggregate utilisation figures; carrier-level or route-level data are not publicly available. This limits the precision of phase two and means the quantitative analysis will support inference at the airport and carrier-category level rather than the individual operator level. I treat this as a scope boundary rather than a fatal constraint: the regulatory design questions in phase one do not require carrier-level data to be answered. Provisional timeline: Michaelmas term — statutory mapping and comparative legal analysis; Hilary term — dataset construction and quantitative analysis; Trinity term — integration, drafting, and submission. This is consistent with a 12-month MSc research project. Oxford's Faculty of Law hosts research on regulatory theory, administrative law, and network industry governance that is directly relevant to this proposal. The Centre for Socio-Legal Studies and the work associated with regulation and governance at Oxford provide a scholarly environment in which the combination of doctrinal and empirical methods used here is recognised as legitimate and has precedent. The Bodleian Law Library holds the statutory materials, CAA publications, and comparative regulatory literature required for phase one. The Oxford Internet Institute's quantitative social science resources are available to MSc students requiring statistical support. This proposal does not name a specific supervisor, as supervision arrangements are subject to departmental allocation. The research question falls within the scope of faculty working on UK administrative and regulatory law, and the quantitative component is sufficiently modest that it does not require specialist econometric supervision beyond standard MSc-level methods support. The expected contribution is bounded: this project will produce the first systematic legal analysis of the post-Brexit UK slot coordination enforcement architecture, supported by quantitative evidence on utilisation patterns, and will identify specific statutory amendments or CAA guidance reforms that would close the identified compliance gaps. That is a feasible and useful output for a one-year research degree.
