Research

My research studies how monetary, fiscal and financial institutions shape macroeconomic outcomes over the long run. A central theme is the interaction between policy regimes and nominal stability: when monetary tools work, how fiscal commitments anchor prices, and how financial regulation affects credit and the real economy. I combine archival and narrative evidence with time-series and causal empirical methods.

Monetary versus Macroprudential Policy: Causal Impacts of Interest Rates and Credit Controls in the Era of the UK Radcliffe Report

With David Aikman and Alan M. Taylor · Reject and resubmit, American Economic Review

How do interest rates and credit controls affect the economy when they are used together? We study Britain from the 1950s to the 1980s, when policymakers relied on both Bank Rate and direct controls over bank lending. We construct a new historical policy dataset and use a factor-augmented local-projection approach to identify the effects of the two instruments. Monetary tightening primarily reduced inflation, while credit controls primarily reduced bank lending and output. The results show that the instruments were not close substitutes, despite policymakers often treating them as such, and help explain the limitations of Britain's anti-inflation strategy during the Great Inflation.

Fiscal Financing Regimes and Nominal Stability: An Historical Analysis

Oliver Bush · Centre for Macroeconomics Discussion Paper 2025-31

This paper asks how governments finance fiscal expansions and why the answer matters for inflation. It compares two British regimes: the Gold Standard era, when policymakers expected higher debt to be backed by future primary surpluses, and the Great Inflation, when fiscal policy was used primarily to manage demand, employment and growth. Narrative evidence from policymakers' stated objectives is combined with empirical estimates of how fiscal balances and prices responded to fiscal shocks. Fiscal expansions were eventually backed in the Gold Standard regime. In the Great Inflation regime they were not, and unexpected inflation played an important role in stabilising the public finances.

‘Muddling Through or Tunnelling Through?’ UK Monetary and Fiscal Exceptionalism and the Great Inflation

With Michael D. Bordo and Ryland Thomas · NBER Working Paper 34063

Why was Britain's Great Inflation so persistent? Standard accounts emphasise unusually large shocks, monetary-policy mistakes and ineffective incomes policies. We reassess the historical and empirical record from the 1950s to the early 1990s and find that these explanations do not fully account for the persistence of inflation and inflation expectations. The evidence instead points to a sequence of regime changes in fiscal as well as monetary policy. During the Great Inflation, fiscal policy ceased to stabilise the public finances and was used to sustain employment and growth, cushion terms-of-trade shocks and support agreements with organised labour. The British case shows why the fiscal foundations of nominal stability matter.

A Narrative Account of the Great Inflation in the UK, 1961–1997

With Michael D. Bordo and Ryland Thomas · NBER Working Paper 34363

This paper provides a detailed narrative of Britain's Great Inflation from 1961 to 1997. It documents the economic conditions at the outset, the distinct phases of the inflation, the features that made the UK different from other advanced economies, and the interaction of fiscal, monetary and incomes policies. By placing each inflationary episode in its institutional and historical setting, the paper supplies a qualitative companion to our analytical work on the fiscal roots of the Great Inflation and contributes to continuing debates over the causes and consequences of persistent inflation.

The Credit-to-GDP Gap and Complementary Indicators for Macroprudential Policy: Evidence from the UK

With Julia Giese, Henrik Andersen, Christian Castro, Marc Farag and Sujit Kapadia · International Journal of Finance & Economics, 19(1), 25–47

This paper evaluates the credit-to-GDP gap as a guide for macroprudential policy in the United Kingdom and compares it with complementary indicators of excessive credit growth and financial vulnerability.

Reducing Debt, Short of Default

With Tom Best, Luc Eyraud and Belen Sbrancia · In Sovereign Debt: A Guide for Economists and Practitioners, Oxford University Press, 2019

This chapter examines the policy options available to governments seeking to reduce high public debt without resorting to default.

GDP-linked Bonds and Sovereign Default

With David Barr and Alex Pienkowski · In Life After Debt, Palgrave Macmillan, 2014

This chapter analyses how GDP-linked sovereign bonds can share macroeconomic risk between governments and investors and affect incentives and outcomes around sovereign default.

Policy research

Alongside my academic research, I work on monetary and financial-stability policy at the Bank of England. This work includes the design of analytical frameworks for financial policy, macroprudential indicators, bank capital requirements, sovereign debt and the international monetary system.
