The UK's decision to leave the EU in the 2016 referendum created substantial uncertainty for UK businesses. The nature of this uncertainty is different from that of a typical uncertainty shock because of its length, breadth and political complexity.

We study stock market reactions to the Brexit referendum on 23 June 2016 in order to assess investors’ expectations about the effects of leaving the European Union on the UK economy.

The aim of this paper is to provide quantitative information about the position of the UK in the network of global value chains (GVCs) and to discuss its implications for the UK's post‐Brexit trade policy. We find that the UK has become much less integrated into global production networks than other EU countries over the period 2000–14, and is almost unique among EU countries in that the domestic content of its exports increased over this period.

This article extends a classic on‐the‐job search model of homogeneous workers and firms by introducing a shirking problem. Workers choose their effort levels and search on the job. Firms elicit effort through wages and monitoring; an inverse relationship between wages and monitoring rates is derived. Wages play a dual role by allocating labor supply and motivating employee effort. This gives rise to an equilibrium wage distribution that contrasts with existing literature. In particular, I show that a hump‐shaped and positively skewed wage distribution, as observed empirically, can be derived even when firms and workers are, respectively, identical.

The business rates retention scheme (BRRS) means that councils bear a proportion of the real-terms change in business rates revenues in their areas. When the BRRS was introduced in 2013–14, this proportion was up to 50%. However, since April 2017, the government has been piloting 100% retention of real-terms changes in business rates revenues in a number of areas of England. From April 2018, a further 10 areas are piloting 100% schemes. In this briefing note, we examine two questions. First, what are the financial implications of the pilots for different councils? In particular, what is the financial benefit to councils taking part in the pilots, and what does this imply for those councils not in pilot areas? Second, what can be learnt from these pilots? The government has explicitly set out what it hopes to learn, but how informative are the pilots actually likely to be?

Consider a simple general equilibrium economy with one representative consumer, a single competitive firm and the government. Suppose that the government has to finance public expenditures using linear consumption taxes and/or a lump-sum tax on profits redistributed to the consumer. We show that, if the tax rate on profits cannot exceed 100 percent, one cannot improve upon the second-best optimum of an economy with constant returns to scale by using a less efficient profit-generating decreasing returns to scale technology.

This note summarises ongoing work being undertaken by Lucie Gadenne, Tushar Nandi and Roland Rathelot on the scale and nature of supply chain distortions in West Bengal. Earlier work examined the effects of reforms to West Bengal’s simplified tax schemes on revenues.

This paper, written collaboratively by IFS researchers and policy-makers from Ethiopia and Ghana, has multiple and interlinked objectives: (i) to provide an overview of tax incentives and best practices for their design grounded in economic principles, and assess how these apply to the case studies of Ethiopia and Ghana; and (ii) to understand more broadly the causal impacts of tax incentives on economic outcomes in developing countries by reviewing the relevant methodologies to conduct rigorous quantitative analysis and the existing empirical literature. Finally, we discuss the policy implications and avenues for research given the existing literature on the causal impact of tax incentives.

As in many high income countries, VAT systems in low and middle income countries (LMICs) are often characterised by different tax treatments for different types of goods and services. Often, reduced rates of VAT and exemptions (“preferential rates”) are granted on equity grounds, for goods and services that are thought to take up a greater proportion of the budgets of poorer households. Given typically limited capacity to redistribute through the direct tax and benefit system, it has been suggested by some economists that such rate differentiation might be the best way for governments to transfer resources to poorer households.

Firm-level investment paths are commonly characterised by periods of low or zero investment punctuated by large investment ‘spikes’. We document that such spikes are important for understanding firm and aggregate level investment in the UK.

In France, in 2014, women’s hourly wages were on average 14.4 % lower than men’s. Beyond differentials in observed characteristics, is this gap explained by segregation of women in low-wage firms, or by gender inequality within a given firm?

This briefing note provides background material for the 2017 General Election. IFS Election 2017 analysis is being produced with funding from the Nuffield Foundation as part of its work to ensure public debate in the run-up to the general election is informed by independent and rigorous evidence.

What is the effect of funding costs on the conditional probability of issuing a corporate bond?

There are growing calls to restrict advertising of junk foods. Whether such a move will improve diet quality will depend on how advertising shifts consumer demands and how firms respond. We study an important and typical junk food market – the potato chips market.
