Statistics Finland has compiled waste statistics since the mid-1980s. The data material included administrative registers, surveys and research results. Waste was initially classified according to a 'Finnish' classification based on composition of waste until the mid-1990s, and later according to the European Waste Catalogue (EWC). A Guide to Waste Classification was drafted to facilitate classification in 1999. The Standard Industrial Classification (NACE) has been employed as a background classification for waste statistics. Waste statistics have been and are being used especially for preparing the national waste strategy and the waste management guidelines, in the planning stage of waste treatment plants, for research, and as supplementary material for compilation of material flow accounting.

This paper proposes an alternative formulation for the Sen-Shorrocks-Thon (SST) index of poverty intensity that is appropriate for survey data with sampling weights. It also decomposes the SST index into the poverty rate, the average poverty gap ratio among the poor, and the overall Gini index of poverty gap ratios. To account for sampling variation in estimates of poverty intensity, this paper uses the bootstrap method to compute confidence intervals and presents international comparisons using Luxembourg Income Study (LIS) data from the 1970s to the 1990s. Cross-sectional and longitudinal analyses indicate that the percentage change in poverty intensity can be approximated by the sum of percentage changes in the poverty rate and average poverty gap ratio, since changes in the overall Gini index of poverty gap ratios are negligible. In the early 1970s poverty intensity in Canada and the United States was almost indistinguishable, but in the 1970s Canadian poverty intensity decreased. Large increases in poverty intensity occurred in the 1980s in the United States, the United Kingdom, and Sweden.

This paper is a critique of the current direction of industrial statistics in the U.S. The sweep includes not just the toolkit of statistical methods most often employed in industry, but also international competitiveness, the corporate climate in which statistical solutions are sought and the educational process which trains applied statisticians. Much is found that is good, but bland endorsement does little to advance a field. Therefore most of the paper is deliberately iconoclastic. Almost all of the extreme viewpoints are rooted in the author's direct experience, working with statisticians and managers across a range of industries. Some of the perspective must be attributed to knowledgable gossip, from friends and students who are now employed by various companies. Incidentally, the paper reviews four new statistical textbooks for engineers and an edited volume of papers on experimental design for industry.

This study investigates productivity growth in broad-acre agriculture in Western Australia. Tornqvist indices of three output groups (crops, sheep products and other) and five input groups (livestock, materials and services, labour, capital and land) are constructed and discussed. Indices of total output and total inputs are also derived and used to form an index of total factor productivity, that is observed to grow at an average annual rage of 2.7%. The input and output indices are also used in the estimation of output supply and input demand equations, derived from a flexible profit function. The Generalized McFadden functional form is used, because it is possible to impose global curvature upon it without loss of flexibility. Asymptotic chi-square tests reject the hypotheses of Hicks-neutral technical change in inputs and in outputs. Technical change is observed to be `materials and services' saving relative to the other input groups, and also appears to favour wool and sheepmeat production relative to the other output groups.

Shelley A. Phipps Journal of Human Resources. 1993.  Vol. 28. No. 1. P. 162-184. 
This paper uses microdata from the 1986 Statistics Canada Family Expenditure Survey to demonstrate that inequality-sensitive poverty measures such as the Foster-Greer-Thorbecke (1984) index are as sensitive to the equivalence scale embodied in the poverty line as the more frequently used head count and poverty gap measures. Indices of the Foster-Greer-Thorbecke variety are useful, however, for revealing demographic subgroups experiencing extreme deprivation, information not provided by the more standard poverty measures. The paper also demonstrates that our understanding of the relative poverty experiences of important demographic subgroups such as children and the elderly can be influenced by our choice of equivalence scale.

David Caplan Economic Trends. 1998.  no 539.
This article reports on work done within the Office for National Statistics (ONS) to improve the measurement of non-market output within the national accounts. The initial ideas were presented in an Economic Trends article in February 1998. This article describes the work which has been done and explains the methodology which is being adopted for some output series from the 1998 Blue Book. This article begins with a description of the issues and looks at approaches to handling these. It then explains the methods used in this years Blue Book and describes the impact on published data. Finally there is a discussion of the areas where research was less successful and the possible direction of future research.

Recently, interest in the methodology of constructing coincident economic indicators has been revived by the work of Stock and Watson (1989b). They adopt the framework of the state space form and Kalman filter in which to construct an optimal estimate of an unobserved component. This is interpreted as corresponding to underlying economic activity derived from a set of observed indicator variables. In this paper we apply the Stock and Watson approach to the UK where the observed indicator variables are those that make up the Central Statistical Office (CSO) coincident indicator. The time series properties of the indicator variables are examined and three of the five variables are first difference stationary and are cointegrated, the remaining two are stationary in levels. We then construct two alternative measures of economic activity, each of which deals with the different orders of stationarity of the variables. The first uses the levels of the observed component variables that allows for the cointegrating relationship. The second imposes stationarity on the I(1) variables before the estimation by taking first differences. The levels index is viewed as the preferred specification as it allows for the long-run relationships between the variables and has a superior statistical fit.

A multivariate time series model with time varying conditional variances and covariances but with constant conditional correlations is proposed. In a multivariate regression framework, the model is readily interpreted as an extension of the seemingly unrelated regression (SUR) model allowing for heteroskedasticity. Each of the conditional variances are parameterized as a univariate generalized autoregressive conditional heteroskedastic (GARCH) process. The descriptive validity of the model is illustrated for a set of 5 nominal European-US dollar exchange rates following the inception of the European Monetary System (EMS). EMS results are compared to estimates obtained for the same model using data over the pre-EMS period, July 1973 to March 1979. When compared to the pre-EMS free float period, the comovements between the currencies are found to be significantly higher over the later period.

The Monte Carlo approach has proved to be a valuable and flexible computational tool in modern finance. This paper discusses some of the recent applications of the Monte Carlo method to security pricing problems, with emphasis on improvements in efficiency. We first review some variance reduction methods that have proved useful in finance. Then we describe the use of deterministic low-discrepancy sequences, also known as quasi-Monte Carlo methods, for the valuation of complex derivative securities. We summarize some recent applications of the Monte Carlo method to the estimation of partial derivatives or risk sensitivities and to the valuation of American options. We conclude by mentioning other applications.

The high income elasticity of demand often estimated for U.S. imports may be a spurious result of omitting new product varieties from the import price indexes. The purpose of this paper is to demonstrate how to incorporate new product varieties into a constant-elasticity-of-substitution aggregate of import prices. This method is applied to U.S. imports of six disaggregate manufactured goods. It is shown that the corrected indexes are able to account for part--but not all--of the high income elasticities.

This article discusses the difficulties in using nineteenth-century census data relating to occupations for the analysis of sectoral labour inputs. The under-recording of seasonal and women's work in the census shifts in occupational classifications, and the systematic removal from the occupied population of women workers is revealed. Reworking of the census figures suggests the possible need to increase the size ofthe agricultural workforce by between 30 and 40 per cent in the mid-Victorian period. A programme of work is suggested to establish a standardized occupational classification system for census data and to estimate labour inputs from farms.

This paper explores some of the social and economic forces shaping the development of official labour statistics in Britain a century ago. It examines the competing fears and ideologies that fuelled the demand for intelligence about the labour market and the major constraints on its provision, such as Treasury control, industrial resistance and the lack of co-ordination between the statistical branches of government. The broader impact of official labour statistics on social politics is discussed in both a British and an international context, with particular reference to the problems of industrial unrest, unemployment and low income destitution. The paper uses a historical perspective to demonstrate the continuing significance of past investigations to British labour statistics.

The Working Party was set up by the Royal Statistical Society because of widespread criticism of UK official statistics collected and reported by the Government Statistical Service. That Service has to be of fine quality, earning and enjoying public confidence and providing accurate, timely and cost-effective data both for governmental and for public use. The Working Party found no evidence of a lack of integrity among government statisticians. However, the organizational and operational framework of the Government Statistical Service is regarded as inadequate. Accordingly four important sets of recommendations are made. Their acceptance is fundamental for the achievement of a high quality of service linked to full public confidence in official statistics.

Establishment surveys based on list frames often use stratified random sampling with a small number of strata, H, and relatively large sample sizes, n_h, within strata. For such surveys, a grouped balanced half-sample (GBHS) method is often used for variance estimation and for construction of confidence intervals on population parameters of interest. In this method the sample in each stratum is first randomly divided into two groups, and then the balanced half-sample (BHS) method is applied to the groups. We show that the GBHS method leads to asymptotically incorrect inferences as the strata sample sizes n_h \rightarrow \infty with H fixed. To overcome this difficulty, we propose a repeatedly grouped balanced half-sample (RGBHS) method, which essentially involves independently repeating the grouping T times and then taking the average of the resulting T GBHS variance estimators. This method retains the simplicity of the GBHS method. We establish its asymptotic validity as \min n_h \rightarrow \infty and T \rightarrow \infty. We also study an alternative method by forming substrata within each stratum, consisting of a pair of sampling units, and then applying the BHS method on the total set of substrata, treating them as strata. We establish its asymptotic validity as \min n_h \rightarrow \infty. We provide simulation results on the finite-sample properties of the GBHS, RGBHS, the jackknife, and the alternative BHS method. Our results indicate that the proposed RGBHS method performs well for T as small as 15, thus providing flexibility in terms of the number of half-samples used. The alternative BHS method has also performed well in the simulation study.
