THE PURE CHARACTERISTICS DEMAND MODEL*

In this article, we consider a class of discrete choice models in which consumers care about a finite set of product characteristics. These models have been used extensively in the theoretical literature on product differentiation and the goal of this article is to translate them into a form that is useful for empirical work. Most recent econometric applications of discrete choice models implicitly let the dimension of the characteristic space increase with the number of products (they have “tastes for products”). The two models have different theoretical properties, and these, in turn, can have quite pronounced implications for both substitution patterns and for the welfare impacts of changes in the number and characteristics of the goods marketed. After developing those properties, we provide alternative algorithms for estimating the parameters of the pure characteristic model and compare their properties to those of the algorithm for estimating the model with tastes for products. We conclude with a series of Monte Carlo results. These are designed to illustrate: (i) the computational properties of the alternative algorithms for computing the pure characteristic model, and (ii) the differences in the implications of the pure characteristic model from the models with tastes for products.     

ENDOGENOUS TIMING IN A MIXED DUOPOLY AND PRIVATE DUOPOLY –‘CAPACITY‐THEN‐QUANTITY’ GAME: THE LINEAR DEMAND CASE*

We consider a game of endogenous timing of sequential choice of capacity and quantity with observable delay in a mixed duopoly and a private duopoly. In mixed duopoly, we find that a simultaneous play at the capacity stage or at the quantity stage can never be supported as subgame perfect Nash equilibrium (SPNE); whereas a simultaneous play at each stage turns out to be the unique SPNE in a private duopoly. In mixed duopoly there is multiplicity of equilibria and all SPNEs require sequentiality at the capacity as well as quantity stage.     

The ‘New Federalism’ and Horizontal Equalization*

Under Stage I of Australia's ‘New Federalism’ policy a given share of Commonwealth tax revenue is to be distributed to the States. This paper examines the States (Personal Income Tax Sharing) Act 1976 and proposes a concrete fiscal equalization criterion consistent with the provisions for equalization in the Act. Distribution models proposed in Mathews (1979) and Commonwealth Grants Commission (1981) are examined and shown not to satisfy this criterion. An alternative is presented.     

The EPAC ‘Growth Papers’: An Assessment*

During 1986 the Economic Planning Advisory Council published a series of six papers examining the role of economic policy in fostering long-term growth. This article provides a review and critical assessment of the EPAC analysis. The fundamental issue at stake is whether long-term growth is a supply-driven or a demand-driven process. In particular, the crucial issue neglected by EPAC is the relationship between aggregate demand, the inducement to invest and the growth of productive capacity. The conclusion is that in order to promote sustained growth, policy must provide the structural and macroeconomic requirements for a sustainable growth of aggregate demand.     

A BOX–COX CONSUMER DEMAND SYSTEM NESTING THE ALMOST IDEAL MODEL*

This article proposes a consumer demand system that has a generalized functional form characterized by the Box–Cox transformation. The new model offers a wider range of responses to both price and expenditure changes than the existing price independent generalized linear models, including the almost ideal demand system. Even with these features, its functional form is relatively simple and easy to interpret and implement. An empirical illustration is given for Japanese demand for nondurable goods and services. The results show that the new model is preferable to the nested models in terms of relative explanatory power and producing reasonable elasticities.
