The U-shape of happiness in Scotland

We examine well-being in Scotland using micro data from the Scottish Health Survey and the UK Annual Population Surveys. We find evidence of a midlife nadir or zenith in Scotland in well-being at around age 50 using a variety of measures of both happiness and unhappiness. We confirm that higher consumption of fruit and vegetables is associated with higher levels of happiness in Scotland. We compare this with evidence for England from the Health Survey of England. The decline in well-being between youth and midlife is comparable in size to the loss of a spouse or of a job and around half of the fall in well-being in the COVID-19 lockdown. We also find a midlife peak in suicides in Scotland. Despite higher mortality and suicide rates in Scotland than in England, paradoxically we find that the Scots are happier than the English. Northern Ireland is the happiest of the four home countries. We also find evidence of U-shapes in England, Wales and Northern Ireland in the mid to late forties.     

Optimal Currency Areas Scottish Economic Society/Royal Bank of Scotland Annual Lecture, 1999

Microeconomic efficiency and market transparency argue in favour of UK membership in EMU and for Scotland’s membership in the UK monetary union and also in EMU. UK seigniorage (government revenues from money issuance) would be boosted by EMU membership. Lender of last resort arrangements would not be substantially affected by UK membership in EMU. The UK is too small and too open to be an optimal currency area. The same point applies even more emphatically to Scotland. The ‘one‐size‐fits‐all’, ‘asymmetric shocks’ and ‘cyclical divergence’ objections to UK membership are based on the misapprehension that independent national monetary policy, and the associated nominal exchange rate flexibility, can be used effectively to offset or even neutralise asymmetric shocks. This ‘fine tuning delusion’ is compounded by a failure to understand that, under a high degree of international financial integration, market‐determined exchange rates are primarily a source of shocks and instability. Instead, opponents of UK membership in EMU view exchange rate flexibility as an effective buffer for adjusting to asymmetric shocks originating elsewhere. I know of no evidence that supports such an optimistic reading of what exchange rate flexibility can deliver under conditions of very high international financial capital mobility. The economic arguments for immediate UK membership in EMU, at an appropriate entry rate, are overwhelming. Monetary union raises important constitutional and political issues. It involves a further surrender of national sovereignty to a supranational institution, the ECB/ESCB. It is essential that this transfer of national sovereignty be perceived as legitimate by those affected by it. In addition, the citizens of the UK have become accustomed to a high standard of openness and accountability of their central bank since it gained operational independence in 1997. The ECB/ESCB must be held to the same high standard, and, while there are grounds for optimism, there still is some way to go there.     

Policy uncertainty and international financial markets: the case of Brexit

ABSTRACT

This study assesses the impact of the Brexit probability on both the UK and on international financial markets, for the first and the second statistical moments. As financial markets are by nature highly interlinked, one might expect that the uncertainty engendered by Brexit also has an impact on financial markets in several other countries. We first estimate the time-varying interactions between UK policy uncertainty, which to a large extent is attributed to uncertainty about Brexit and UK financial market volatilities. Second, we use two other measures of the perceived probability of Brexit before the referendum, namely daily data released by Betfair and results of polls published by Bloomberg. Based on these data sets, and using both panel and single-country SUR estimation methods, we analyse the Brexit effect on levels of stock returns, sovereign CDS, 10-year interest rates in 19 predominantly European countries, and those of the British pound and the euro. We show that Brexit-induced policy uncertainty will continue to cause instability in key financial markets and has the potential to damage the real economy in both the UK and other European countries. The main losers outside the UK are the ‘GIIPS’ economies: Greece, Ireland, Italy, Portugal and Spain.     

The CO2 ‘trade balance’ between Scotland and the rest of the UK: Performing a multi-region environmental input–output analysis with limited data

In this paper we attempt an empirical application of the multi-region input–output (MRIO) method proposed by Turner, Lenzen, Wiedmann and Barrett [Turner, K., Lenzen, M., Wiedmann, T., Barrett, J., 2007. Examining the global environmental impact of regional consumption activities — part 1: a technical note on combining input–output and ecological footprint analysis. Ecological Economics 62 (1), 37–44] in a recent issue of this journal in order to enumerate the CO2 pollution content of interregional trade flows between Scotland and the rest of the UK (RUK). We extend the analysis to account for direct emissions generation by households, as final consumers, and to a social accounting matrix (SAM), where a more comprehensive account of incomes and expenditures is possible. While the existence of significant data problems mean that the quantitative results of this study should be regarded as provisional, the interregional economy-environment IO and SAM framework for Scotland and RUK allows an illustrative analysis of some very important issues in terms of the nature and significance of interregional environmental spillovers within the UK and the existence of a CO₂ ‘trade balance’ between Scotland and RUK.     

Addressing shortfalls in TIA care in the UK: an economic perspective

Abstract

Objective: To estimate the clinical outcomes and costs associated with reconfiguring the management of TIA in the UK to offer patients rapid access to outpatient clinics for specialist assessment and treatment.

Methods: An economic deterministic model was run comparing two pathways – one arm representing current clinical care based on national guidelines and clinical practice and patient referral to a weekly outpatient clinic, and a revised care pathway replicating phase 2 of the EXPRESS study with patient referral to a daily outpatient clinic. The outcomes of the model were measured in terms of recurrent strokes avoided and net budget impact to secondary care.

Results: Reconfiguring TIA care pathways in the UK could result in the avoidance of 8,164 recurrent stroke events. The model predicts savings of £25,573,279 for the UK healthcare system over 12 months. Annual net savings are predicted in England (£24,916,011), Scotland (£80,554) and Northern Ireland (£1,041,817). In Wales, increased costs of £450,435 are estimated.

Limitations: Using the data published from the EXPRESS study, it is not possible to model a stepwise approach to implementing the revised TIA care pathway. It is therefore assumed that it would be possible to implement the revised TIA care pathway as detailed in the EXPRESS study across the UK and achieve the reduction in recurrent stroke risk that was reported.

Conclusions: The model suggests that the reconfiguration of TIA care pathways in the UK to offer rapid access to treatment and assessment could prevent TIA-related future stroke events and potentially result in cost savings to the healthcare system.     

Strong dependence in the real interest rates

The stochastic behaviour of the real interest rates in ten European countries, Canada and the US is examined in this article by means of fractionally integrated techniques. Using a procedure, specifically designed for testing I (d) statistical models, the results show that the real interest rates are more persistent in some countries like France, Belgium or the USA than in others like the UK or Germany.     

DEMOCRATIC AID AND THE DEMOCRATIZATION OF RECIPIENTS

We investigate whether democratic aid flows, which are directed toward the democratization of recipients by covering democracy‐related programs and government and civil society activities, affect the future political regime of recipient countries. We introduce a multinomial multivariate logit model and we use 5‐yr averaged data covering the period 1972–2004 for 59 democracy aid‐recipient countries categorized into three broad classes according to the prevalent political regime. We find strong evidence that democratic aid flows are positively associated with the likelihood of observing a partly democratic or a fully democratic political regime in democratic aid‐recipient countries and that this result is robust to the potential endogeneity of democratic assistance.(JEL D70, F35, C25)     

SHOULD A MANDATORY SUBORDINATED DEBT POLICY BE INTRODUCED IN THE UNITED KINGDOM? EVIDENCE FROM THE ISSUANCE ACTIVITY OF BANKS AND BUILDING SOCIETIES

Current research is beginning to question the role and effectiveness of traditional rules‐based bank regulatory oversight in favor of incentive‐compatible regulatory design and market discipline and, in particular, mandatory subordinated debt market discipline. However, research on the suitability of a mandatory subordinated debt policy (MSNDP) has focused primarily on the United States. The primary aims of this article, therefore, are to examine the market for subordinated debt (SND) issued by UK credit institutions and to assess the suitability of introducing an MSNDP into UK banking regulation. A further contribution of this article is that it explores SND issuance and its characteristics at a bank level and, uniquely, considers them in relation to regulatory, structural, and economic events that either are specific to the UK or otherwise affect international banks. The article compares the UK findings with research on SND markets in the United States and Europe and, in so doing, raises concerns over whether an MSNDP for the largest global credit institutions would be feasible. Although the focus of this study is the UK banking industry, the country‐focused bank‐level approach provides conclusions that might be relevant to other countries considering the implementation of an MSNDP.(JEL G18, G28)     

The impacts of innovations and standards on trade of measurement and testing products: empirical results of Switzerland’s bilateral trade flows with Germany, France and the UK

Nowadays, the impact of the measurement and testing infrastructure on economic performance and trade is theoretically and even politically widely accepted. However, there are no empirical studies on this issue. The purpose of this paper is to elucidate the impact of innovative capacity and technical standards as one important part of the measurement and testing infrastructure on international trade flows and competitiveness. In order to focus on the direct causality between innovative technology and measurement and testing standards and the respective market, the empirical analysis concentrates on the trade of measurement and testing products of a country with a top position in measurement and testing technology. In its empirical analysis of Switzerland’s trade flows with Germany, France and the UK, the paper follows the approach of the pioneering paper of Swann et al. (Economic Journal 106 (1996) 1297), who integrated for the first time technical standards as a technology indicator in the estimation of UK trade performance. The trade flows in measurement and testing products from 1980 until 1995 are explained by both an indicator for innovative capacity and for the degree of standardisation. The first indicator is based on the patent applications at the European patent office. The latter uses the stocks of technical standards in the countries differentiated by their regional scope. Four different trade equations are analysed, besides an export and an import function, the trade balance and the intra-industry trade. The results clearly show that both Switzerland’s innovative capacity and its stocks of standards are able to explain its export performance in the three countries. Secondly, especially the stocks of international standards in Switzerland have a positive impact on imports into Switzerland from the three countries, confirming their positive role for fostering trade in general. Thirdly, Switzerland’s export surplus concerning the three trade partners is positively affected by the stocks of international standards in Switzerland, which seem to be an important factor for international competitiveness. Finally, the results of the intra-industry model underline the common view of the general trade-fostering effect of even national standards in the case of the trade with the three countries.     

Is health care really a luxury in OECD countries? Evidence from alternative price deflators

This article examines whether real Health-care Expenditure (HE) is a luxury or necessity for Organization for Economic Co-operation and Development (OECD) countries over the period 1972 to 2004 within a panel unit root and panel cointegration framework. To realize this objective, we regress HE on real Gross Domestic Product (GDP), the proportion of the population aged over 65 (P65) and a time trend (T). We first present results for 18 countries where real HE per capita is obtained using a general GDP deflator. For these countries, we find that health care is a luxury for just one country. Next, we present results for eight countries where real HE is obtained using a specific health-care price index. When the general GDP deflator is replaced with a specific health-care price index, at least one of the GDP, P65 or T coefficients for the eight countries changes in a reasonably dramatic fashion, suggesting that the use of the GDP deflator introduces bias into the regression. We find that HE is a necessity in all eight countries. Given that the reliability of the GDP deflator results is questionable, on the basis of the results for the eight countries, we conclude that HE is a necessity.     

A semiparametric approach to value-at-risk,expected shortfall and optimum asset allocation in stock–bond portfolios

This paper investigates stock–bond portfolios' tail risks such as value-at-risk (VaR) and expected shortfall (ES), and the way in which these measures have been affected by the global financial crisis. The semiparametric t-copulas adequately model stock–bond returns joint distributions of G7 countries and Australia. Empirical results show that the (negative) weak stock–bond returns dependence has increased significantly for seven countries after the crisis, except for Italy. However, both VaR and ES have increased for all eight countries. Before the crisis, the minimum portfolio VaR and ES were achieved at an interior solution only for the US, the UK, Australia, Canada and Italy. After the crisis, the corner solution was found for all eight countries. Evidence of “flight to quality” and “safety first” investor behaviour was strong, after the global financial crisis. The semiparametric t-copula adequately forecasts the outer-sample VaR. These findings have implications for global financial regulators and the Basel Committee, whose central focus is currently on increasing the capital requirements as a consequence of the recent global financial crisis.     

Trade patterns and institutional change in East Asia

We investigate how trade patterns – institutionally intensive exports (IIX) – affect institutional quality in East Asia compared to the rest of the world, and whether the effect changed due to the Asian financial crisis. To examine this, we use panel data of 117 countries for the period 1988–2007. Our fixed effect model estimation reveals that the effect of IIX on institutional quality is negative and significant for East Asia, while the effect is insignificant for the rest of the world. The negative effect in East Asia is more pronounced for the five East Asian countries that were strongly affected by the crisis – South Korea, Indonesia, Malaysia, the Philippines and Thailand – than for other East Asian countries. Furthermore, our results reveal that the negative effect for East Asia does not change significantly after the crisis, both in the short and long term, and that improvement in institutional quality after the crisis is not different from that of the rest of the world. This suggests that the crisis had no significant impact on East Asia's institutional quality or on the effects of IIX on institutional quality.     

Scotland as an optimal currency area

The June 2016 UK referendum on continued EU membership where the people of Scotland voted to remain, while the rest of the United Kingdom voted to leave, once again makes the issue of whether Scotland is an optimal currency area very topical. England voted strongly to leave Europe while Scotland backed remain by 62% to 38%. The Scottish government published its draft bill on a second independence referendum in October 2016. The move does not mean another referendum will definitely be held, but this does raise the possibility that Scotland might choose independence and staying in the EU without the rest of the United Kingdom. If Scotland charts a course of independence from the rest of the United Kingdom, then they would likely either issue their own currency or join or form another currency area. In this paper, we test the microeconomic foundations of a common currency area for Scotland, United Kingdom, and the rest of the United Kingdom without Scotland. We find that the United Kingdom, Scotland, and the United Kingdom without Scotland all meet the microeconomic criteria for a common currency area. In contrast, banking data suggest that lending in Scotland is different from lending in the rest of the United Kingdom, adding some doubt to the issue of whether or not Scotland is a common currency area with the United Kingdom.     

Deriving Long-Run Inequality Series from Tax Data*

Prior to the last three decades, regular surveys on household income were rare or non-existent in many developed countries, making it difficult for economists to develop long-run series on income distribution. Using taxation statistics, which tend to be available over a longer time span, I propose a method for imputing the incomes of non-taxpayers, and deriving the underlying distribution of income. Because taxation statistics are typically disaggregated by gender, it is possible to derive separate income distribution series for men and women in countries where individuals file separately. I show that over the past four decades, the distribution of adult male incomes and the distribution of family incomes are highly correlated. Applying this method to Australia, I develop a new annual series for inequality from 1942 to 2001. Inequality fell in the 1950s and the 1970s, and rose during the 1980s and 1990s – a pattern similar to that in the UK.     

Costs of managing severe hypoglycaemia in three European countries

Abstract

Objectives: To assess the costs of severe hypoglycaemic events (SHEs) in diabetes patients in Germany, Spain and the UK.

Methods: Healthcare resource use was measured by surveying 639 patients aged ≥16 years, receiving insulin for type 1 (n=319) or type 2 diabetes (n=320), who experienced ≥1 SHE in the preceding year. Patients were grouped by location of SHE treatment: group 1, community (family/domestic); group 2, community (healthcare professional); group 3, hospital. Costs were calculated from published unit costs applied to estimated resource use. Costs per SHE were derived from patient numbers per subgroup. Weighted average costs were derived using a prevalence database.

Results: Hospital treatment was a major cost in all countries. In Germany and Spain, costs per SHE for type 1 patients differed from those for type 2 patients in each group. Average SHE treatment costs were higher for patients with type 2 diabetes (Germany, €533; Spain, €691; UK, €537) than type 1 diabetes patients (€441, €577 and €236, respectively). Telephone calls, visits to doctors, blood glucose monitoring and patient education contributed substantially to costs for non-hospitalised patients.

Conclusions: Treatment of SHEs adds significantly to healthcare costs. Average costs were lower for type 1 than for insulin-treated type 2 diabetes, in all three countries.     

Cost effectiveness of memantine in Alzheimer's disease in the UK

Objective: This analysis assesses the cost-effectiveness of memantine for the treatment of moderate-to-severe Alzheimer's disease (AD) in the UK.

Methods: This cost-utility analysis was based on a Markov model. The model simulated 5-year progress of patients with AD until they need full-time care (FTC), defined as a patient becoming either dependent or institutionalised. Transition probabilities were based on a predictive equation, derived from the London and South-East Region epidemiological study. Resource use, utilities and mortality were obtained from the same study. Memantine efficacy was based on a meta-analysis of six large trials. The model compared memantine to its alternative in the UK, i.e. no pharmacological treatment or background therapy with acetylcholinesterase inhibitors.

Results: Memantine was found to delay the need to FTC by 6 weeks compared with current practice in the UK. It was associated with increased quality-adjusted life-years and cost savings to the healthcare system (probability of this outcome was 96%). The projections were made assuming that benefits from the 6-month treatment were sustained over time, which is regarded as the main limitation. The model underwent extensive sensitivity analyses, which confirmed the base-case findings.

Conclusions: The model suggests that memantine delays the need for FTC and decreases cost. It can be regarded as a cost-effective choice in the management of moderate and severe AD.     

The cost-effectiveness of onabotulinumtoxinA for the prophylaxis of headache in adults with chronic migraine in the UK

Abstract

Background:

Although chronic migraine is associated with substantial disability and costs, few treatments have been shown to be effective. OnabotulinumtoxinA (Botox, Allergan Inc., Irvine, CA) is the first treatment to be licensed in the UK for the prophylaxis of headaches in adults with chronic migraine. This study aims to evaluate the cost-effectiveness of onabotulinumtoxinA in this indication in the UK.

Methods:

A state-transition (Markov) model was developed comparing onabotulinumtoxinA to placebo. Efficacy data and utility values were taken from the pooled Phase III REsearch Evaluating Migraine Prophylaxis Therapy (PREEMPT) clinical trials program (n?=?1384). Estimates of resource utilisation were taken from the International Burden of Migraine Study (IBMS), and stopping rules were informed by published medical guidelines and clinical data. This study estimated 2-year discounted costs and quality-adjusted life years (QALYs) from the UK National Health Service perspective.

Results:

At 2 years, treatment with onabotulinumtoxinA was associated with an increase in costs of £1367 and an increase in QALYs of 0.1 compared to placebo, resulting in an incremental cost-effectiveness ratio (ICER) of £15,028. Treatment with onabotulinumtoxinA reduced headache days by an estimated 38 days per year at a cost of £18 per headache day avoided. Sensitivity analysis showed that utility values had the greatest influence on model results. The ICER remained cost-effective at a willingness to pay threshold of £20,000–£30,000/QALY in the majority of scenario analyses as well as in probabilistic sensitivity analysis, where onabotulinumtoxinA was cost-effective on 96% of occasions at a threshold of £20,000/QALY and 98% of occasions at £30,000/QALY.

Conclusion:

OnabotulinumtoxinA has been shown to reduce the frequency of headaches in patients with chronic migraine and can be considered a cost-effective use of resources in the UK National Health Service. The uncertainties in the model relate to the extrapolation of clinical data beyond the 56-week trial.     

Forecasting Inflation with the Hybrid New Keynesian Phillips Curve: A Compact-Scale Global VAR Approach*

ABSTRACT

In this article, the multihorizon predictive power of the Hybrid New Keynesian Phillips Curve (HNKPC) is analysed by making use of several close- and open-economy specifications for the headline inflation of six developed countries. The key element is the use of direct measures of inflation expectations – Consensus Forecast – embedded in a compact-scale Global VAR (GVAR) environment, becoming the baseline open-economy HNKPC (OE-HNKPC) specification. These OE-HNKPC point forecasts are evaluated using the Root Mean Squared Forecast Error (RMSFE) statistic and statistically compared with several benchmarks, including traditional atheoretical models. Several OE-HNKPC as well as a closed-economy HNKPC (CE-HNKPC) specifications are also analysed. The results indicate that in four out of six countries, the CE-HNKPC is the best forecasting model, whereas for the same countries, a parsimonious OE-HNKPC is the second-best alternative, and in most cases, outperforming traditional statistical benchmarks. The RMSFE is obviously affected by the unanticipated effects of the Great Financial Crisis (GFC), spoiling out the performance of a number of competing forecasts. However, when considering an evaluation sample just before the crisis, both the CE-HNKPC and the parsimonious OE-HNKPC still come out as the best forecasting models. Furthermore, these preferred models also do an excellent job tracking inflation better than the best atheoretical models during the GFC.     

THE ISSUES RAISED BY THE EXPERIENCE OF UTILITY PRIVATIZATION IN THE UK

ABSTRACT^**: The UK utilities have all had a change of ownership over the last decade and a half. Does it really change things and, if so, in what ways? In fact, very little research has been carried out on this much copied experiment and evidence on efficiency gains is not that strong. But two main things have emerged. First, regulation and competition are the key drivers of change. It may well be that privatization was needed in the UK to allow these things to happen. It does not follow, however, that in other industries, or other countries, change is dependent on privatization. Second, different groups gain and lose (in absolute and relative terms) from privatization. In the UK, shareholders and large consumers have gained far more than small consumers, ex-employees and the tax payer. In particular, the fact that low-income consumers have done less well than the generality of consumers raises important issues for social cohesion and for policy.     

The impact of the post-1972 floating exchange-rate regime on US exports

By employing the techniques of cointegration and error-correction models, this article empirically investigates the impact of the post-1972 floating exchange-rate regime on the volume of US bilateral exports to Canada, Germany, Japan and the UK. The econometric models specified in the analysis were estimated using quarterly data for the sample period 1959:1–1997:4. The empirical results provide evidence that the post-1972 exchange-rate regime is less conducive to trade than the Bretton-Woods fixed exchange rate regime.
