Technology acceptance: Not all organisations or workers may be the same

The Technology Acceptance Model (TAM) is widely accepted by researchers in the IT field as a reliable tool able to predict acceptance of new technology by individuals. The majority of these studies have used participants (both students and non-students) from within traditional businesses functions, e.g., accounting and finance. The ability of TAM to predict technology acceptance across all situations is not well documented. During the past decade there has been an increasing interest in research within Not-for-Profit (NFP) organisations. This paper considers whether people likely to pursue careers within the NFP sector have different attitudes to technology and whether such differences affect the measures used within technology acceptance models. A survey of business and social science undergraduate students, those most likely to enter careers in the Business vs. the NFP sector, indicated differences between the two groups that may impact on the technology acceptance models.     

Volatility clustering and the bid–ask spread: Exchange rate behavior in early Renaissance Florence

This paper investigates the nature and behavior of the domestic (local) currency market that existed in Florence (Italy) during the late 14th and early 15th centuries (a.k.a. the Early Renaissance). We find that the extant volatility and microstructure models developed for modern asset markets are able to describe the statistical volatility properties observed for the denaro-florin exchange rate. Volatility is clustered and is related to the bid–ask spread. This supports the notion that, although there are huge social, industrial and technological differences between capitalism then and now, individuals trading financial assets in an organized venue behave in a similar manner.

Collapsing oil prices and a falling dollar set the background to a Budget in which the Chancellor, hamstrung by lower oil revenues, was seen as having little room for manoeuvre. In fact the sharp fall in the sterling price of oil has provided him with the perfect excuse for not making significant cuts in personal income tax that were largely irrelevant to the needs of the economy. Instead of a boost to household demand we have had, thanks to OPEC, a transfer to companies in the form of a reduction in costs. This should enable them to expand output against a background of falling inflation. Our post-Budget assessment of macroeconomic prospects (Section I), made on the Treasury's assumption of a $15 oil price, shows output growing by 2 1/2 per cent this year and inflation falling below 3 per cent in 1987. We are thus less optimistic than the Treasury about output but more optimistic about inflation. How was the Chancellor able, within the confines of the Medium-Term Financial Strategy, to give anything away having lost so much oil revenue? A detailed analysis of the PSBR forecast (Section II) reveals good reasons why non-oil tax revenues should be some £3 1/2n higher than forecast this time last year. But, because we still expect public spending to be above the official figures, our PSBR forecast is £1bn higher than the Treasury's. Although the macroeconomic impact of the Budget was small (especially in relation to that of the fall in oil prices which preceded it), it continued the process of tax reform. We focus, in Section III, on the new proposals to deal with the problem of the pension fund surpluses to which we drew attention in the November issue of Financial Outlook. We conclude that the proposed measures could have a larger effect on tax revenues in the longer term than is indicated by the Treasury's Budget estimates.     

Spatial heterogeneity and interregional spillovers in the European Union: Do cohesion policies encourage convergence across regions?

Using a spatial econometric perspective, the speed of convergence for a sample of 163 regions of the European Union (EU) over the period 1981–1996 is estimated. For this purpose, we use a specification strategy which allows an explicit modeling of both spatial heterogeneity and spatial autocorrelation found in the analyzed sample. The estimated final model combines groupwise heterocedasticity, the identification of two spatial regimes and spatial dependence. Our results show how an appropriate consideration of the role of spatial effects can shed new insights into the European convergence process. We find that regions in the EU cohesion-fund countries (Ireland, Greece, Portugal and Spain) are converging separately from the rest of regions of the EU. Our estimations indicate that over the analyzed period, there was a faster conditional convergence in relative income levels of the regions belonging to Cohesion countries (5.3%) than in the rest of the regions of the EU (3.3%). Therefore, our results contrast with other evidence that points to the fact that the convergence process in Europe has weakened or even has stopped at the beginning of the 1980s. Moreover, our work shows clear evidence of separate spatial convergence clubs among EU regions.     

THERE'S MANY A SLIP…

There has to be a General Election at some time in the next eighteen months. It has long been clear that the economy will not be in the best of shape in time for the election and that the best the Conservatives can hope for is a significant reduction in inflation and interest rates together with modest output growth. Our October forecast suggested that this combination was feasible and that the government would be able to go to the country with base rates of 12 per cent, retail price inflation at half its present level and output growing at a rate of 2per cent after a relatively short and shallow recession. It may turn out that this is an overly optimistic central forecast and in this Forecast Release we examine some of the ways in which it could go wrong. In a worst possible scenario the government may have to face the electorate with the economy in recession, inflation high and interest rates still at or close to their present levels.     

Estimating the Impact of Anti-dumping and Anti-cartel Actions Using Intervention Analysis

Intervention analysis is proposed as a method for estimating the effects of anti-dumping actions in the presence of a domestic cartel. Data requirements and modelling effort compare favourably with traditional structural model approaches. The method is applied to an anti-dumping action brought to the European Commission and in which the European producers of the product were fined after an anti-cartel action by the Commission covering an overlapping period. Interven tion analysis is applied to distinguish the effects of the anti-dumping action from those of changes in cartel behaviour     

A lorenz curve based index of income stratification

Conclusion This paper introduced a method of calculating the proportion, and its standardized index, of the GINI coefficient that is due to the overlapping of the incomes of different groups in a population. This Lorenz curvebased index measures the degree to which all groups, collectively, form different strata in a population as opposed to the degree to which an individual group forms a stratum in the population. It is useful for describing the degree of integration or segregation in a population as opposed to the degree of integration or segregation of a group within a population. The new index was applied to distributions of wage and salary income for individuals and family income for households. The results indicate that racial/ethnic income stratification is more marked among men than women.     

Equality of responsibility: Cultural conditions for Western survival

Multiplying populations and communications weave an increasingly dense web of mutual interdependence, factual and psychological, and therewith multiple demands, often unwelcome, often conflicting, on the individuals whom they support. The responsibility which this imposes on individuals, and which Western societies must develop and enforce if they are to survive, is inconsistent with the concept of unqualified personal autonomy which has emerged, partly as a protest against it.     

Efficient Timing of Retirement

This study introduces a retirement decision into the classic Merton model. A familiar result is that you should retire if and when the marginal utility of another year's wages is equal to the disutility of work. A new result is that at the point of retirement your exposure to risky assets should not jump. Under power utility and constant time preference, the retirement timing problem has a closed form solution; the nine inputs to the formula in question give rise to nine comparative-static results on retirement timing. Further specialization of preferences, to log consumption utility and zero time preference, reduces the required number of inputs to four.
