Memories of hard won victories: amateur moviemaking contests and serious leisure

Contests are one of the most successful stimuli to production within the amateur moviemaking sector. Despite pleas from some commentators that moviemakers should view their practice as non-competitive civic participation, many more consciously sought out the public recognition that came from winning an award at regional, national and international film competitions. The ‘Ten Best’, an annual production competition that ran from 1936 to 1986, is of particular note as it was the highlight of the year for many amateur moviemakers who referred to it as ‘our Oscars’. Focusing on a Ten Best prize-winning film from the Merseyside region, War Declared (1985), consideration of this title encourages empirical data gathering to be extended beyond primary print sources by drawing on original interviews conducted with local cine-club members. While some filmmakers see the pursuit of awards as a superficial path to follow, others viewed the ‘Ten Best’ as setting the standard for others to aspire to. These interviews revealed that amateur moviemakers have mixed feelings about the central role of contests and awards in the amateur sector. However, the potential satisfaction and/or ‘compensation’, which winning can provide, overrides the perceived costs and secures the cultural value of participants’ work.

International equality of stock market returns

Real returns, excess returns, and nominal returns from stock markets in 11 developed countries are compared for the difference in their means and variances by using a new procedure to test their equality and to determine if one stock market dominates another. The sample period from January 1973 to September 1989 is divided into three subperiods. Results show that stock markets in the United States and Germany dominate those in the other countries in early sub-periods, but not in a recent sub-period, to indicate an increasing capital market integration. Integration with Germany has increased more than with the United States, due possibly to the European Monetary System.     

A New Method for the Identification of Patterns in Input–Output Matrices

This paper suggests a new algorithm for selecting the input–output (IO) coefficients of a Leontief matrix in order of importance, so providing an analytical method for decomposing an IO matrix. It avoids the choice of arbitrary thresholds for eliminating flows or coefficients, and allows for circular relationships. For this purpose, a simple inverse-important criterion has been chosen, which is consistent with the logic of the Leontief model. A procedure that greatly reduces the computational burden is then devised. This method permits new comparisons of IO structures of different countries or regions, for identifying their different degree of internal integration and their reciprocal influence through the exchange of intermediate goods. An application to an IO model for seven European Community countries for 1980 is then presented.     

Alcohol taxation and regulation in the European Union

This article surveys alcohol consumption, taxation and regulation in the European Union (EU). It uses the estimates of cost-of-illness studies to gauge the external costs of harmful alcohol use. In all but one member state, the costs exceed alcohol excise duty collections. An optimal alcohol excise is difficult to design, because the welfare gains from a reduction in socially costly heavy drinking must be balanced against the welfare loss from a fall in moderate drinking. This suggests that while an alcohol excise increase may be efficiency improving, complementary regulatory measures, which focus on specific problem groups, should be an important element of the policy package. A case can also be made for reducing wasteful cross-border shopping by raising the minimum duties on wine, beer and spirits, preferably in line with their relative alcohol content.      

Option Pricing For Jump Diffusions: Approximations and Their Interpretation

We derive a computable approximation for the value of a European call option when prices satisfy a jump-diffusion model with the coefficients depending explicitly on time. This is achieved by approximating the original coefficients with functions that are piecewise constant in time. We give an interpretation of the approximating option values, in particular in the context of a discrete-time model associated with the approximating continuous-time model.
