The prospects are considered of deploying batteries and fuel cells in order to reduce the carbon emissions from various modes of transport. It is proposed that the government has not done enough to advance these technologies and that Britain is lagging behind other countries. The adequacy of Britain’s future supplies of energy is called into question.

Climate change is a complex global issue that requires widespread understanding, support and collaboration for effective solutions. This research delves into the crucial role of communication in tackling climate change and reaching net-zero goals. Leveraging advanced machine learning techniques, we focus on 10 core climate change topics derived from social media conversations over time. This analysis underscores the importance of a holistic and interconnected approach, involving a diverse array of policies at local, national and global levels to combat climate change effectively and attain net-zero objectives. We offer key policy suggestions that can significantly contribute to this vital cause.

Offshore wind farms (OWF) are now in operation and increasingly under construction as scalable, sustainable energy sources. In fact OWFs are currently the cheapest form of new energy projects in Europe. The levelized cost of energy (LCOE) for OWF has fallen drastically due to decades of innovation facilitated by both taxpayer and private sector funding. This emerging industry is experiencing massive worldwide growth with the potential to accelerate the decarbonization of regional and the global economy as well as bring a reliable source of green hydrogen into commercial use, all with minimal disruption to ecosystems and impacts on biodiversity. This paper provides a historical perspective of wind energy harnessing and shows that wind turbines are the oldest, largest and one of the smartest machines. We also highlight the potential of offshore wind energy to provide new solutions to (a) meet clean energy demand for a growing world population, (b) improve energy security of nations through other downstream technologies such as production and storage of dispatchable fuel (such as green hydrogen battery storage) and (c) through supply complementarity improve resilience of nuclear power plants in high-seismic-activity areas. Offshore wind industry can also become a gold standard for future industries, and the paper provides insights into the new green economics and jobs and factories for the future. We show that environment-friendly regulation is driving innovations even further to enhance sustainability of OWF. Examples include material recycling, landfill ban on blade disposal and ecofriendly low-noise offshore construction to protect biodiversity.

Net zero greenhouse gas emissions by 2050, the UK’s current target, requires bridging a dramatic energy transition and eliminating all other net sources of emissions while ensuring a just transition. Key components like renewable electricity generation and electric vehicles are well developed, but many issues remain. Public support for a green economy may wane if the economic costs are too high or seen as unfair. Therefore, although renewable energy is cheaper than fossil fuels, it is essential to maintain employment, real per capita growth and reduced inequality. Decarbonizing the UK economy requires an integrated sequential approach and need not be delayed while dealing with the aftermath of the COVID-19 pandemic, energy crisis and resulting inflation.

Several decades ago, Sig Prais concluded that the root cause of the UK’s poor industrial performance was the poor quality of education and training. In this lecture, I will make a related argument, focussing on the lack of opportunity in the United Kingdom for workers who have not succeeded in the formal education system and the long-lasting impacts this has on their economic, health and social wellbeing. I will highlight the importance of providing opportunities for continued training over a worker’s lifetime for appropriate skills that are valued in the workplace in order to achieve inclusive growth.

Adam Smith promoted free banking—private, competitive, convertible banknotes. He also supported restrictions on banks. We study Smith’s views and the era in which they developed, suggesting his ‘regulations’ were a backstop against banks’ risks to depositors but primarily monetary stability. In modern parlance, Smith supported macroprudential regulations to underpin monetary stability, as did Friedman and Schwartz the US FDIC. We discuss why Smith’s vision for banking went unrealised. Bank regulation became microprudential and ran aground in 2008/2009. The prominence of macroprudential regulation now provides a chance to reorientate regulation to support monetary stability. Early signs are not promising.

Adam Smith saw the division of labour and specialisation as the driver of ‘universal opulence’, a process limited by the scope of the market. He also believed that competition was essential to ensure growth benefited the public. Yet eventually there could be a trade-off between these two mechanisms. In today’s era of global production networks, the markets at certain links in supply chains may support just one specialised supplier; and in winner-take-all digital markets there is a single supplier even at global scale. When the scope of the market is global, there may be a trade-off between specialisation and competition.

A key insight from Adam Smith is that economists should base their conclusions about a monetary institution or policy on a careful study of the history of that institution or policy, a study that includes the experiences of other countries. To illustrate Smith’s reliance on financial history we cover five current monetary problems that have close analogies with problems that Smith discussed: (1) inflation, (2) banking panics, (3) public debt, (4) usury laws, (5) central bank digital currencies.

For path-breaking insights on how prices can guide the efficient allocation of resources and how innovation and investment can spur economic growth, Adam Smith is justly renowned. He was, however, well aware of problems posed by market dominance—specifically in banking and, more generally, wherever getting to the scale that delivers increasing returns leads to monopolistic behaviour. For the historical record, we draw on the recent wide-ranging survey by Acemoglu and Johnson on how the benefits of innovation have been spread across society since the Industrial Revolution. We also consider these issues in the context of geo-political competition.

Duncan Black, like Adam Smith before him, was trained at, and taught at, the University of Glasgow. Like Smith, Black followed the Enlightenment in appreciating the importance of theory and of its empirical applications. Black sought to apply the ideas of a schedule of preferences and a conception of equilibrium, to politics, as Smith had done in economics. Black believed that his median voter theorem could generalize to a theory of politics, much as Smith’s contributions did for market economics. Black did not complete that generalization, but William Riker did offer a theory of institutional politics, designed to complete Black’s project.

This article reviews Adam Smith’s clearly articulated views about the desirability of free trade and his equally strong view on the necessity of sound institutions and ‘the tolerable administration of justice’ as key ingredients of successful economic management. It starts with Smith’s views on free trade and shows how pertinent they are to today’s high-level trade policy challenges. It then considers a more detailed day-to-day instrument of policy—the Trade Remedies Authority (TRA). Following Brexit, the TRA was created as an arms-length body for investigating cases for granting temporary import restrictions to specific products according to a reasonably well-defined objective process. The article demonstrates how, over the first 2 years of its life, the TRA has been reduced from a useful administrative instrument to a fig leaf for a political process for granting protection to petitioners. Unfortunately, this tendency to displace analytical approaches to policy by purely political ones can now be observed in many activities of UK governance.

Emissions are directly linked to economic output and consequently subject to business cycle fluctuations. The present study analyses the interactions between climate policies and business cycles through the lens of a New Keynesian dynamic stochastic general equilibrium model. We compare a static cap-and-trade policy with a dynamically adjusting policy in terms of macroeconomic stabilisation, welfare and emissions price dynamics. The results of the quantitative evaluation suggest that a constant policy leads to lower aggregate volatility but is associated with larger welfare costs. In contrast, under the dynamic policy emissions prices and labour markets display less variations.

This article is a response to a piece in this journal, by David Bartram, which questions the validity of a vast literature establishing consistently a U-shaped relationship between age and happiness. There are 618 published studies that find U-shapes in that relationship in 145 countries, and only a handful that do not. Of the 30 countries that Bartram (2023, National Institute Economic Review, 1–15) examines, he finds U-shapes in 18. We show compelling evidence of U-shapes in the remaining dozen countries. Supporting evidence of a U-shape is found in objective measures including deaths of despair, depression, stress and pain that are worst in midlife.

Inflation rates and their convergence within Euro area have been a major concern, since well before the advent of the single currency. Inflation differentials are a normal phenomenon in any monetary union and even in long-established monetary unions. The aim of this research is to examine the main factors of inflation differentials in the Euro-zone for the period 1999–2018. Our empirical estimates appear to suggest that a one-percentage-point increase in the positive output gap typically leads to an increase of about 20 basis points in the inflation rate of EMU countries. We also find three structural breaks, in 2004, 2008 and in 2010. Since the monetary policy of the European Central Bank is geared at maintaining low and stable inflation, the productivity growth should be increased, and the real effective exchange rates should be decreased and become more homogeneous among EMU. Therefore, countries’ inflation differentials may become less persistent.

We show consumer expectations indices from the Conference Board and the University of Michigan predict unemployment upticks in the USA up to 18 months in advance, both at national and at state level. These data predict six of the last six recessions called by the NBER Business Cycle Dating Committee 6–18 months before the date of recession. The consumer expectations data for 2021 and 2022 are consistent with recession.

The pandemic-induced economic crisis has seen a massive increase in savings as households could not spend their income. The last time that consumers were seriously rationed was during the Second World War. This article models the behaviour of households during the War years and its immediate aftermath in Ireland, Sweden, the US and UK. Savings were held in liquid form and, once the War was over and rationing eased, a consumption boom transpired. However, significant excess savings were converted into physical assets in the housing market. There is evidence that this pattern is being repeated as the Covid-19 crisis eases.

We apply insights from the political economy of secession to analyse the early years of the Irish Free State (IFS). The IFS was fortuitous in a debt settlement that enabled it to begin its existence debt free while also receiving financial assistance to quell civil unrest. Yet the IFS was unable to continue to provide the welfare spending inherited from the old regime thereby exacerbating inequality. The IFS also maintained a sterling peg, which led to a milder experience of the depression era. Ultimately, however, the benefits of independence were not forthcoming in the early years of the IFS.

Debate around Wales’ place in the United Kingdom has intensified over recent years, with radically differing visions for the union of the Welsh and UK governments emerging alongside growing (though still minority) support for Welsh independence. This article argues that these constitutional debates must be considered alongside Wales’ current fiscal position. Wales’ estimated fiscal deficit is reflective of long-standing economic underperformance as part of the UK, which we argue is unlikely to be addressed under current economic, fiscal and constitutional arrangements. On the other hand, it also suggests a difficult economic outlook for an independent Wales, which would require tough fiscal and economic choices to address Wales’ apparent balance of payments deficit.

In this paper, we investigate devolution in the Northern Irish context. The role of institutional geography is highlighted. Both contemporary and historical (c. 1921–1972) devolution models are discussed. It is argued that institutional factors provide explanations for economic weaknesses found under both devolution models. The evidence presented suggests that the institutional geography has both changed and exhibited continuities and we discuss these features in relation to contemporary issues. In particular, it is argued that institutional geography considerations have shaped the creation of the current review of tax devolution as well as the creation of an independent fiscal council.

This article examines the key features of the UK’s spatial productivity relationships and discusses some of the key questions currently being articulated or debated as they relate to potential devolution-related discussions. The paper demonstrates that the local productivity challenges facing UK regions are nationwide in nature rather than local, and systemic rather than specific. In particular, the scale-productivity relationships across cities and regions which are evident in almost all other OECD countries are largely absent in the UK. Instead, previous prosperity is the dominant marker of current local prosperity, suggesting that cumulative causation processes define the UK regional and urban economic landscape rather than scale relations. This article explains these features in a manner which is accessible to a wide audience, in order to provide greater clarity regarding the fundamental economic problems to be addressed and also the underlying objectives which the Levelling Up agenda needs to achieve.
