Converting customer expectations into achievable results

It is not enough in today's environment to just meet customers' expectations--we must exceed them. Therefore, one must learn what constitutes expectations. These needs have expanded during the past few years from just manufacturing the product and looking at the outcome from a provincial standpoint. Now we must understand and satisfy the entire supply chain. To manage this process and satisfy the customer, the process now involves the supplier, the manufacturer, and the entire distribution system.     

Land-Use Controls and Housing Costs: An Examination of San Francisco Bay Area Communities*

This paper reports on our efforts to gauge the effects of land use controls on housing markets. We discuss how land use controls affect land and housing markets and explain why communities use such controls to restrict development. We present the results of an econometric model created to assess the inflationary effects of land use controls on housing costs. The model is based on data assembled in the San Francisco Bay Area. The model results indicate that density controls and land availability do systematically affect the price of new housing units.     

A review of statistical methods in the analysis of data arising from observer reliability studies (Part I)*

Summary This paper reviews research situations in medicine, epidemiology and psychiatry, in psychological measurement and testing, and in sample surveys in which the observer(rater or interviewer) can be an important source of measurement error. Moreover, most of the statistical literature in observer variability is surveyed with attention given to a notational unification of the various models proposed. In the continuous data case, the usual analysis of variance (ANOVA) components of variance models are presented with an emphasis on the intraclass correlation coefficient as a measure of reliability. Other modified ANOVA models, response error models in sample surveys, and related multivariate extensions are also discussed. For the categorical data case, special attention is given to measures of agreement and tests of hypotheses when the data consist of dichotomous responses. In addition, similarities between the dichotomous and continous cases are illustrated in terms of intraclass correlation coefficients. Finally, measures of agreement, such as kappa and weighted-kappa, are discussed in the context of nominal and ordinal data. A proposed unifying framework for the categorical data case is given in the form of concluding remarks.     

The role of buyer power in oligopoly models: An empirical study

This study investigates whether an industry's profitability and concentration are influenced by structural characteristics of the industries and final markets to which it sells. Very few similar studies have been made, and there is some dispute about their conclusions. This study discusses the methodological problems behind this dispute and the ways in which the specification and data used here avoid these problems. The results show that seller profitability rises with the extent to which buyers are dispersed across many industries, but that no other buyer characteristic exerts a significant influence on either the profitability or the concentration of the selling industry.

If I were to try to read, much less answer, all the attacks made on me, this shop might as well be closed for business. I do the very best I know how—the very best I can—and mean to keep doing so until the end.     

From market failure to organisational failure

In this paper, we argue that environmental economists who have dedicated their attention to problems of market and regulatory failure have been remiss in ignoring the potential for failure in the one institution that actually manages environmental resources - the business firm. Traditionally the firm has been modelled as a unitary, rational, optimising persona ficta. There is, however, abundant empirical and theoretical evidence to suggest that the business firm is an imperfect institution in that there are systematic deviations between the environmental objectives of the firm's leaders (principals) and the actions of the firm's employees (agents) which determine environmental performance. In the paper, we draw parallels between the causes of market failure and public policy tools to correct them on one hand and the causes of organisational failure and the management tools suited to their remedy on the other. Although much of the paper is concerned with the interrelationship between public policy that promotes sustainability and business policy to fashion a sustainable enterprise, our work is relevant irrespective of the reason why a firm's principal may want to improve environmental performance. No matter what the reason, the principal must concern him- or herself with operationalising objectives in management systems. It is consistent with the precautionary principle to assume that employees will do what the firm measures and rewards, not what its principal says is important. We build a verbal model, based on the language of principal-agent theory, to analyse how different management instruments might be employed to improve the firm's environmental performance. The model is one of three decision makers in a vertical hierarchy. Each of the first two has various instruments at its disposal to influence the behaviour of the agents subordinate to it. In the end, the goal is to ensure consistency between social, economic, and personal objectives. The specific management tools we analyse, with reference to the formal modelling which has appeared in the literature, include the compensation system, quantification and monitoring of non-financial objectives, internal pricing, horizontal task restructuring, centralisation vs. decentralisation of decision making, and corporate sanctions of agents for negligence. We conclude the paper by reiterating that the corporate policy statements to the effect that the firm should respect the environment are insufficient to ensure that result. In addition, firms' principals must operationalise that goal in the systems of measurement and control which govern the behaviour of those who really matter - the employees.     

On Long-term Forecasting of Social Security: A Robustness Analysis

In this paper we present a macro-economic demographic growth modelhaving a special focus on social security. It is designed to study the variability of responses of the system in presence of risks and uncertainties. Here we analyze the robustness of the model towards uncertainties in parameterspecifications, introduced by ARCH-M models with the incorporation ofintervention processes. The parameters varied are labor force participationrates (one of the key sources of uncertainty in the social security policydebate), and the parameters of the production function (the key source ofuncertainty in any long-run economic analysis). The sensitivity analysisfocuses on two variables: assets of the private pension system and thebalance of the public `Pay As You Go' pension system. Special attentionis given to convergence properties of the macro-economic model.
