The Bank of England and HM Treasury are currently working with Nottingham and Stanford Universities to run a pilot survey of firms across the UK on their expectations for future growth of sales, employment, investment, costs and other outcomes. This survey collects expectations from UK firms about the impact of Brexit shocks in a more timely way than other currently available indicators from the ONS, which lag behind events on average by at least 3 months. This proposal seeks to enlarge the panel of firms to allow for greater representativeness of the data, collection of data from the same panel participants over 3 years (we expect further Brexit shocks) and to allow us to conduct detailed analysis of subset of firms by industry, type and region. The data we are collecting is timely and important for immediate policymaking, business decisions and Brexit negotiations. The fact that this project has the full support of the Chief Economists of HM Treasury (Sir David Ramsden) and the Bank (Andrew Haldane) is evidence that the project is timely and important for UK decision making. This data would be used for three purposes: A) Research: We would investigate the impact of the Brexit (and other) shocks, in terms of both uncertainty but also mean impacts. Armed with our large panel of at least 2500 firms per month, and after matching this data into annual accounts data from Amadeus, industry and regional data (e.g. LFS and Comtrade) and ONS micro-data, we will then investigate a number of questions. For example, how has Brexit impacted investment and hiring, how does this vary across regions, industries, firm sizes, ages and growth rates? How is this related to the initial enthusiasm for Brexit, and how are other policies affecting this? Are firms expectations consistent with the eventual outcomes (since we follow these firms over time) and what factors appear to influence these expectations? Are firms over-optimistic (too high mean) and over-confident (too high variance) as is often seen in surveys of senior managers? The project will generate important answers to these questions, which will be used to generate international journal publications, as we draw upon unique and timely data during a period of immense change. The basis of the evaluation of the data will be detailed economic analysis using state of the art panel data methods. B) Policy: The Bank and Treasury are both responding to the Brexit shock with only limited guidance on its impact on the UK economy. Having a minimum panel of 2500 firms at high frequency (monthly) will provide the data that we (and others) can use to explore uncertainty, subjective views of economic conditions and investment, sales and employment impacts by region and industry. We will introduce specialized questions to evaluate policy announcements on Brexit dates, policy positions on trade, immigration and steps to mitigate its impact. C) Data: Following on prior projects we will rapidly make available public indices of sales, investment, employment and price sentiments (e.g. the size weighted average monthly expected changes, and some lower frequency regional and industry indices). This will be extremely useful for policy makers, but also private firms trying to navigate the Brexit process. Secondly, we will provide on-line anonymized micro-data for business users and academics, and for registered users the full micro-data (confidentially). Our commitment to do this is highlighted by the extensive online provision in prior projects like www.worldmanagementsurvey.com and www.policyuncertainty.com This project will provide cutting-edge results, both in terms of the academic analysis but also in the service it provides to key policy institutions such as HM Treasury and the Bank of England. This is made possible by the unique data set developed by a trans-Atlantic collaboration of Professors Mizen and Bloom and the specialist inputs of the C-Is in the Bank of England (Thwaites and Young).
