Each year, the government decides how much to raise benefits and tax allowances. In the UK, the basis for these upratings is rarely debated, yet has major long‐term consequences for the relative living standards of different groups as well as for the public finances. This paper considers the medium‐term implications of present uprating policies, which vary across parameters of the tax–benefit system. Continuing these policies for 20 years, other things staying the same, would result in a near doubling of the child poverty rate alongside a substantial gain to the public finances. At the same time, pensioners are largely protected by the earnings indexation of pensioner benefits including, in time, the basic state pension. We show how difficult it will be to meet the UK child poverty targets unless the greater inequality inherent in the current regime for uprating payments and allowances is redressed.  相似文献

The mean-variance hedging approach for pricing and hedging claims in incomplete markets was originally introduced for risky assets. The aim of this paper is to apply this approach to interest rate models in the presence of stochastic volatility, seen as a consequence of incomplete information. We fix a finite number of bonds such that the volatility matrix is invertible and provide an explicit formula for the density of the variance-optimal measure which is independent of the chosen times of maturity. Finally, we compute the mean-variance hedging strategy for a caplet and compare it with the optimal stategy according to the local risk minimizing approach.

In this paper, we present a practical methodology for variance estimation for multi‐dimensional measures of poverty and deprivation of households and individuals, derived from sample surveys with complex designs and fairly large sample sizes. The measures considered are based on fuzzy representation of individuals' propensity to deprivation in monetary and diverse non‐monetary dimensions. We believe this to be the first original contribution for estimating standard errors for such fuzzy poverty measures. The second objective is to describe and numerically illustrate computational procedures and difficulties in producing reliable and robust estimates of sampling error for such complex statistics. We attempt to identify some of these problems and provide solutions in the context of actual situations. A detailed application based on European Union Statistics on Income and Living Conditions data for 19 NUTS2 regions in Spain is provided.  相似文献

Using survey data from 2009 to 2011, we analyse the effects of the recent euro area economic, financial and private debt crisis on the supply of and demand for bank finance for small and medium enterprises (SMEs). At the country level, we identify three distinct aspects of the recent crisis in the euro area affecting firm credit through different channels. Controlling for country fixed effects, the impact of a weak real economy on firm credit operates both by reducing firms’ demand for bank financing and by lenders increasing loan rejections and tightening terms and conditions on credit allocated. On the other hand, financial conditions have no significant effect on demand, but they do affect credit supply as we find that financial tensions worsen the chances of obtaining credit and its terms and conditions. We interpret this as evidence of a bank balance sheet channel negatively impacting credit provision. We find that private sector indebtedness has important effects on SMEs’ credit access and its terms and conditions.  相似文献

Drawing on the organizational learning literature, our study examines the role of foreign market knowledge and firm emphasis on technological innovation in the internationalization of small, entrepreneurial firms in the Czech Republic. It is based on a sample of 168 SMEs representing a broad range of manufacturing industries that were founded after the fall of communism and as the Czech economy was transitioning to a more market-based economy. Findings indicate that emphasis on technological innovation is associated with greater acquisition of foreign market knowledge. In addition, our results indicate that emphasis on technological innovation directly and indirectly influences the performance of such SMEs in international markets. Our findings also suggest that foreign market knowledge partially mediates the relationship between firm emphasis on technological innovation and international performance. Implications of our findings from the perspective of theory and practice are discussed.  相似文献

In the last decade, the demand for sustainable and social investments has improved. The mutual funds industry has responded to market needs by offering a number of investment products focused on Environmental, Social and Governance (ESG) companies. The aim of this article is to understand if an ESG score can actually be considered a valid criterion that portfolio managers could adopt, along with traditional risk–return optimisation, in selecting asset portfolios. The paper analyses the link between the performance and the ESG score of different sectoral portfolios (one for each sector of the Global Industry Classification Standard), entirely composed of ESG assets, in the search for a clear and strong positive correlation that could suggest an overall advantage to focus on an ex ante choice of assets with high ESG scores.  相似文献

This paper analyses the regulation of the market of voice call termination on mobile networks, by considering the remedy of asymmetric access charges and the hypothesis of discriminatory retail pricing. In the two way interconnection, the operators revenue depends on two factors: the retail price and the access charge. If the retail prices are different between calls that terminate on the same network (on-net) and calls that terminate on the rival network (off-net), the competition is more complex, involving positive networks externalities for the incumbent operator. In order to reduce the competitive disadvantage for new entrants and smaller operators many European regulation authorities have introduced the remedy of asymmetric access charges. This paper is aimed at analysing the effectiveness of this regulatory measure, assuming that operators are differentiated in terms of brand loyalty and cost structure.  相似文献

A broad debate about the harmonization of public sector accounting standards in Europe is underway. The authors provide arguments in favour of harmonization, but they also acknowledge the existing pluralism and diversity by taking stock of the state of play in 14 European countries. The paper makes a proposal for a way forward for policy-makers and standard-setters, in which the benefits of harmonization can be obtained without obliging EU member countries to necessarily abandon their current public sector accounting systems.  相似文献
