The economic costs and benefits of UK defence exports

This study examines the economic costs and benefits to the UK of a 50 per cent cut in UK defence exports from the average level of 1998 and 1999. The net impact on the government budget is estimated to be an ongoing loss of between around £40 million and £100 million a year: around 0.2–0.4 per cent of the total UK defence budget. In addition, there is estimated to be a one‐off net adjustment cost, spread over five years, of between £0.9 billion and £1.4 billion. A further more speculative adjustment cost (estimated at around £1.1 billion) could result if the loss of income associated with the ‘terms‐of‐trade£ effect were also included. In terms of the wider debate about defence exports, the results of this study suggest first that the economic effects of the reduction in defence exports are relatively small and largely one‐off, and secondly that the balance of arguments about UK defence exports should be determined mainly by non‐economic factors.     

Equity and efficiency effects of redistributive policies

How do various forms of redistribution affect the distributions of earnings and consumption and their intergenerational mobility? Do redistributive policies enhance efficiency by mitigating market imperfections? Or do they create a trade-off between equity and efficiency? To address these issues, a dynamic general equilibrium model is constructed and solved numerically. The effects of the degrees of targeting of money transfers and educational transfers and the relative performance of the two types of transfers are examined.     

Social Security Design in the UK: What is optimal?

This paper uses a simple model of how households at different points on the income distribution make decisions about saving and labour supply to illustrate some of the problems government faces in designing social security systems. We show simulation results, which highlight the costs and benefits of alternative pension and income support regimes, and analyse what is happening in the UK in the light of the results.     

Incentives at the counter: An empirical analysis of surcharging card payments and payment behaviour in the Netherlands

In card payment systems, no-surcharge rules prohibit merchants from charging consumers extra for card payments. However, such rules are prohibited in the Netherlands. Dutch retailers are allowed to surcharge consumers for debit card use. This setting permits an empirical analysis of the impact of surcharging card payments on merchant acceptance and consumer payment choice. Based on consumer and retailer survey data, our analysis shows that surcharging steers consumers away from using debit cards towards cash. Half of the observed difference in debit card payment shares across retailers can be explained by this surcharge effect. Removing debit card surcharges may induce cost savings of more than EUR 50 million in the long run.     

Government spending on research and development in the UK

This paper explores the extent of current UK government spending on science and technology placed in its recent historical context. The allocation of this spending across the different arms of government, the primary purposes of the expenditures undertaken and the extent to which the government performs as well as funds R&D are also explored, with some international comparisons analysed. The political and institutional processes that determine the revealed patterns of expenditure in the UK, the rationales behind such spending and the aims and objectives of the main spending departments are discussed, as is the interaction with EU expenditures on science and technology. The effectiveness of or pay-off to government support of this kind is also considered before future spending plans are addressed.     

Redistributive impact of indirect tax reforms: Greece, 1988–2002

This paper assesses the distributional impact of indirect taxes among Greek households between 1988 and 2002, a period that coincides with the introduction of significant reforms in the tax system due to EU membership. The highly differentiated indirect tax structure prevailing at the beginning of the period had distributional benefits over the more simplified 2002 tax structure. The overall inequality of the after‐tax welfare distribution has increased by 6–12½ per cent and changes in the indirect tax system seem to explain about half of this increase. The paper also applies a recent method of measuring the distributional impact of relative price changes caused by changes in tax rates of commodities (Newbery, 1995) and establishes that indirect tax reforms introduced since 1988 had an adverse impact on the distribution of purchasing power, which nevertheless seems to be very small.     

Spot price modeling and the valuation of electricity forward contracts: The role of demand and capacity

We propose a model where wholesale electricity prices are explained by two state variables: demand and capacity. We derive analytical expressions to price forward contracts and to calculate the forward premium. We apply our model to the PJM, England and Wales, and Nord Pool markets. Our empirical findings indicate that volatility of demand is seasonal and that the market price of demand risk is also seasonal and positive, both of which exert an upward (seasonal) pressure on the price of forward contracts. We assume that both volatility of capacity and the market price of capacity risk are constant and find that, depending on the market and period under study, it could either exert an upward or downward pressure on forward prices. In all markets we find that the forward premium exhibits a seasonal pattern. During the months of high volatility of demand, forward contracts trade at a premium. During months of low volatility of demand, forwards can either trade at a relatively small premium or, even in some cases, at a discount, i.e. they exhibit a negative forward premium.     

Allocation of decision rights and the investment strategy of mutual funds

The literature suggests that while decentralized decision making can allow for greater specialization in an organization, it heightens the cost of coordinating decisions. The mutual fund industry—in particular, sole- and team-managed balanced funds—provides an ideal setting to test the specialization versus coordination trade-off, as information on decision structures and fund actions is easily obtained. We show that sole-managed balanced funds, with centralized decision rights, exhibit significant market timing that requires reallocation across asset classes. However, consistent with coordination difficulties between managers specializing in particular asset classes, no market timing is evident in team-managed balanced funds. Team-managed funds exhibit greater returns from specialization, in the form of better security selection performance than sole-managed funds. These results hold cross-sectionally and for funds that switch management structures. The overall returns across different management structures are similar, indicating a market equilibrium. Investor flows reward market-timing performance for sole- but not team-managed funds.     

Social security in the UK under New Labour: what did the Third Way mean for welfare reform?

In 1997, the Labour Party was elected in the UK with few explicitly articulated ideas about social security reforms. This paper reviews the large number of subsequent reforms to social security, and argues that some consistent themes have emerged. A commitment to keep to the tight spending plans of the previous, Conservative, administration left little scope for increases in benefit spending during the first two years in office. Since that time, increases in the generosity of some social security programmes have been directed towards achieving certain goals. An emphasis on encouraging paid work has been a consistent theme, whilst aims of reducing poverty rates for children and pensioners have been emphasised since 1999. Spending to achieve these goals has often been directed through means‐tested programmes, and there has been a related weakening of the link between paid National Insurance contributions and benefit entitlements. It remains to be seen whether reforms to the process of income assessment will increase take‐up.     

An Analysis of Contrarian Investment Strategies in the UK

The performance of contrarian, or value strategies – those that invest in stocks that have low market value relative to a measure of their fundamentals – continues to attract attention from researchers and practitioners alike. While there is much extant evidence on the profitability of value strategies, however, most of this evidence pertains to the US. In this paper, we provide a detailed characterisation of value strategies using data on UK stocks for the period 1975 to 1998. We first undertake simple one-way and two-way classifications of stocks in which value is defined using both past performance and expected future performance. Using sales growth as a proxy for past performance and book-to-market, earnings yield and cash flow yield as measures of expected future performance, we find that that stocks that have both poor past performance and low expected future performance have significantly higher returns than those that have either good past performance or good expected future performance. Allowing for size effects in returns reduces the value premium but it nevertheless remains significant. We go on to explore whether the profitability of value strategies in the UK can be explained using the three factor model of Fama and French (1996). Broadly consistent with the results for the US, we find that using the one-way classification the excess returns to almost all value strategies can be explained by their loading on the market, book-to-market and size factors. However, in contrast with the US, using the two-way classification there are excess returns to value strategies based on book-to-market and sales growth, even after controlling for their loading on the market, book-to-market and size factors.     

Targeting fuel poverty in England: is the government getting warm?

This paper examines the cost‐effectiveness of the new Home Energy Efficiency Scheme (HEES), a key component of the UK government's Fuel Poverty Strategy. The impact on the fuel poverty gap is simulated using data on a large‐scale and representative sample of households in England. The scope for improving the scheme's targeting is considered by examining the optimal allocation of grants between households. The extent to which these potential gains might be achieved in practice using pragmatic criteria for distributing grants, and the implications of taking into account the dynamics of fuel poverty and the self‐selection of grant applicants, are also explored. The current scheme is unlikely to have a very significant impact on fuel poverty, and considerable gains could be achieved by redesigning HEES, although the paper also highlights the difficulties involved in efficient targeting, including some additional complications not encountered in the analysis of more traditional anti‐poverty measures.     

Credit spreads: An empirical analysis on the informational content of stocks,bonds, and CDS

This paper explores the dynamic relationship between stock market implied credit spreads, CDS spreads, and bond spreads. A general VECM representation is proposed for changes in the three credit spread measures which accounts for zero, one, or two independent cointegration equations, depending on the evidence provided by any particular company. Empirical analysis on price discovery, based on a proprietary sample of North American and European firms, and tailored to the specific VECM at hand, indicates that stocks lead CDS and bonds more frequently than the other way round. It likewise confirms the leading role of CDS with respect to bonds.

Incorporating risk input into the analysis of bank productivity: Application to the Taiwanese banking industry

This study reappraises banks’ productivity by using 42 Taiwanese banks during 1999–2007 as observations. It introduces an input-oriented generalized metafrontier Malmquist productivity index (I-gMMPI), while considering the latent effect of risk-taking behavior in the analytic framework. We learn that public and private banks should face separate short-term technological frontiers, while the econometric model considering risk input can portray banks’ operating frontiers better. Moreover, neglecting the influence of risk input would bring about distortions of efficiency, technology and TFP dynamic estimations for banks; meanwhile, the degree of scale economies would also be overestimated. The paper concludes that neglecting the risk-taking essence in bank performance evaluation is equal to allowing banks to barter risk-bearing as the term for further output growth. Consequently, the potential cost is that banks may excessively aggrandize their scales of business, implying the possibility of another financial crisis.     

Optionality and Daily Dynamics of Convenience Yield Behavior: An Empirical Analysis

In this article I empirically examine the daily convenience yield behavior for six commodity markets (crude oil, heating oil, gasoline, wheat, corn, and copper). The results illustrate that convenience yield behavior can be statistically explained within an option pricing framework. However, because one of the assumptions of the standard call option formula is not fully satisfied by the observed convenience yield series, an alternative option—exchange option—may be more appropriate for modeling the daily convenience yield behavior. Furthermore, I empirically test two hypotheses on convenience yield behavior. The results confirm the assertion that the convenience yield is increasing in marginal production costs. In addition, the findings offer limited support for the hypothesis that the convenience yield is decreasing in the serial autocorrelation of spot prices. The observed switch in the sign of regression coefficients as the order of autocorrelation increases is attributed to the probable presence of mean reversion in these markets.     

The Performance of the Foreign‐Owned Sector of UK Manufacturing: Some Evidence and Implications for UK Inward Investment Policy

This paper analyses the reported performance of foreign‐owned manufacturing subsidiaries in the UK between 1994 and 1998. The paper is set in the context of uncertainty about the performance of some foreign‐owned sectors of UK manufacturing and the implications of this performance for the beneficial spillover effects sought by policy‐makers from foreign‐owned capital. Japanese‐owned subsidiaries are the focus of particular attention, with reported profits and tax liabilities significantly below those of subsidiaries from other national sources. The wider ramifications of this finding are analysed for the UK case, particularly in terms of the need to take into account the wider exchequer effects of inward investment in the general evaluation of the financial assistance provided to foreign firms.
