Are prices of new dwellings different? A spectral analysis of UK property vintages

The work makes two contributions to Hui’s (2011) dynamic house price classification. First, a house price ripple in cycles from Modern to Older dwellings is revealed and, second, as New housing is shown to have lower volatility than the other two. Using spectral analysis, it is argued that there is a 7½-year repeat buyer-second-hand cycle and a five year, first time buyer-New housing cycle, common to three house price vintages. These cycles reinforce each other every fifteen years, which corresponds with a Minsky super-cycle in housing finance. The equity of the owner-occupier is fortified by higher house prices whereas new builds extract embedded equity from the market. Government should support builders and facilitate access to market to first time buyers and through programmes like Help-to-Buy 1. However, to address the greater price instability that should follow, Government should impose a capital gains tax on the house seller

EU enlargement and the portuguese economy

Ten states, primarily from Central and Eastern Europe, will be admitted to the EU in 2004. The present paper assesses the competitiveness implications of this enlargement for Portugal. Four specific topics are considered: the trade and industry effects, the implications for Portugal's ability to attract FDI, the likely levels and consequences of immigration from Central and Eastern Europe and the implications for Portugal's budgetary relations with the rest of the EU.Financial support of the Fundação para a Ciência e a Tecnologia /MCT under SFRH/BD/6412/2001 (supported by the European Social Fund)

Effect of the sodium reduction and smoking system on quality and safety of smoked salmon (Salmo salar)

Excessive sodium (Na) intake has been associated with high blood pressure and cardiovascular diseases. Therefore, sodium reduction is a public health challenge worldwide. The aim of this study was to develop smoked salmon with a reduced Na content. Sodium chloride (NaCl) was replaced by potassium chloride (KCl) at 25% and 50% (molar replacement) and studied in combination with two smoking procedures (natural wood and liquid smoke) as well as two smoking temperatures (18-19ºC or 56ºC). Smoked salmon samples were characterized by physicochemical, sensory and microbiological analyses. No major differences were observed regarding physicochemical properties in the studied treatments. Smoked samples with 50% of NaCl replaced by KCl were slightly more bitter than those with 25% whereas samples with 25% of replacement did not show differences to those with non-reduced Na content (5 g of added NaCl per 100 g of salmon). Molar Na:K ratio decreased from 4,3 in controls to 1,4 and 0,6 in samples with a NaCl reduction level of 25% and 50 % respectively. Microbiological assessment indicates that 2-week shelf-life would be appropriate and safe in terms of accomplishment of the EU regulation, taking into account foreseeable storage temperatures (up to 8 ºC). Thus, it is possible to achieve a reduction of 25-50% of NaCl in smoked salmon by replacing NaCl by KCl and considerer this product as a “source” of K.info:eu-repo/semantics/acceptedVersio

Hidden properties of Irish house price vintages

Using spectral analysis, prices of two Irish house vintages are investigated for hidden periodicities. What emerges is a major periodicity consistent with an Irish business cycle. A further hidden intermediate cycle in second-hand housing, that is common to all areas of Eire but featured not nearly so prominently in new housing, is posited to be related to life events and space stress. By revisiting the housing market more often, the repeat buyer injects additional volatility in house prices. It is proposed that housing policy should be directed at reducing the number of repeat buyers as a means of deflating property bubbles

Higher Education as modulator of gender inequalities: Evidence of the Spanish case

Raising educational levels may help to reduce inequalities between men and women in certain social and economic aspects. Using statistics for Spain, we analyse labour market behaviours such as the rates of activity and unemployment by sex according to the educational level. The results reveal that the differences between men and women decrease as the educational level increases. In particular, the modulator effect of education is very important at the higher level, where differences in labour market behaviour between men and women with an university education almost disappear, except in terms of salaries. Nevertheless, it can be seen that the current economic crisis has reduced the modulator role of education in gender differences in Spain
