Economics of shortage and non-price control

The main ideas and concepts of Economics of Shortage (by János Kornai) and Non-Price Control (edited by János Kornai and Béla Martos) are summarized. Then the notion of a normal state, and the significance of quantity signals in economic control processes are discussed, along with Kornai's views about the role of prices in economic adjustment, and the nature of the budget constraints that agents face. Finally, the paper explores the relationship between Kornai's analysis and the various types of macroeconomic equilibrium recently discussed by Malinvaud.     

Exact moments of the sample autocorrelations from series generated by general arima processes of order (p, d, q), d=0 or 1

Formulae for the numerical computation of the first four exact moments of the sample autocorrelations, given a time series realisation from a general autoregressive moving average process of order (p, d, q) with d=0 or 1, are presented. The exact mean and variance of the sample autocorrelations are computed for various sample sizes and several time series models. The evaluated results are compared with those obtained from approximate formulae for the mean and variance of the sample autocorrelations. A specification of the numerical accuracy of the first two exact moments is included.     

On the importance of a generalist conception of human resource management: A cross-national look

What is human resource management? The term risks becoming devalued if it is associated with particular approaches to the management of people, to labor relations, or to the development of the personnel function. These aspects of HRM have to be seen in context—indeed, HRM is best viewed as the management of organizational context, as “governance.” This is the challenge for general management, supported by personnel generalists.     

Dimensions of Performance Effectiveness In High-Involvement Work Organisations

Sharon Parker, Sean Mullarkely and Paul Jackson, who are researchers in the MRC/ESRC Social and Applied Pyschology Unit at the University of Sheffield, draw on detailed case study evidence to consider the substantial changes to the shop floor roles entailed in high involvement work organisations. They argue that specification of the performance requirements of such roles will facilitate employees taking on appropriate behaviours, reduce role confusion, and enable consistency in human resource practices. They discuss the use of repertory grids to explore the models of effective performance held by production managers and derive nine critical dimensions of shop floor employee performance from the analysis. These contain specific behavioural examples and are grouped around four higher-order dimensions: ‘process ownership’, ‘social skills’, ‘personal style’, and loss prevention’. These dimensions form the basis of a broader specification of the skills, knowledge and general orientations required by shopfloor employees in high involvement roles.     

How Might Companies Value ESOs?

There has been a steady growth in the use of employee equity compensation plans, and in the use of executive stock options (ESOs) in particular, along with a rise in shareholder and public perceptions that the values of compensation plans are not always fully disclosed. The IFSA of Australia recently called for separate reporting in financial statements of numbers and values of ESOs. Companies, when negotiating employment contracts, frequently agree to compensate an executive if a share option plan is subsequently not approved by shareholders. These facts suggest that reporting the value of an ESO plan is a useful and important exercise. We outline a model for the valuation of ESOs typically issued by Australian listed companies and illustrate the application of the model with a case study.     

Value and liquidity under changing market conditions

Papers studying the liquidity of a market tend to focus on decisions involving the trade-off between the selling price and the time-till-sale for a given set of market conditions. This paper characterizes market conditions using a price-probability locus; a change in market conditions is some combination of changes in the level and/or slope of this locus. I show how the effect of either type of change on price and on the probability-of-sale can be decomposed into those commonly associated with an increase in the value and those which involve a substitution between price and probability. Two adding-up conditions restrict the set of possible predictions. Though the discussion focusses on real estate market, where scarcity is rationed by a mechanism which combines search and bargaining, the same ideas apply to markets with other types of selling mechanisms.
