Endogenous recessions: The creative destruction effect of final product novelty

In this paper we build a basic macroeconomic model aimed to grasp some aspects of the inner functioning of macroeconomic fluctuations. We highlight a mechanism through which the appearance of a product innovation results in an eventual reduction of the aggregate economic activity. When a new product appears, demand moves towards this more attractive product. The ‘creative destruction’ effect in this context is represented by the resources lost when firms producing old varieties exit the market due to the shortage of demand. Because firms producing a given product receive on average the same amount of demand, exits happen to be highly synchronized. We use this fact to explain the fluctuation asymmetries observed in real data. We test the ability of the model to meet features of real data against the United States' GDP in the 1950–1992 period.     

Comment on 'Market discipline and monetary policy' by Carl Walsh: a reply

In their interesting paper, Fabia de Carvalho and MaurícioBugarin alter the informational assumptions I employed in Walsh(2000) and discuss how this change affects the results reportedin my paper. The structure of the underlying model I used, and therefore     

Endogenous objectives and the evaluation of targeting rules for monetary policy

Recent research in monetary economics has followed the advice of McCallum [1988. Robustness properties of a rule for monetary policy. Carnegie-Rochester Conference Series on Public Policy 29, 173-203] and investigated the robustness properties of monetary policy rules by evaluating them in a variety of models. Evaluation across models is typically based on an exogenously specified loss function. However, the theory on which many recent monetary policy models are based implies that changes in the structure of the model also have consequences for the policy objectives the central bank should pursue. Objectives are endogenous, not exogenous to the model. In this paper, I investigate the impact of endogenous objectives on the evaluation of targeting rules for monetary policy.     

Creating jobs through public subsidies: An empirical analysis

This paper analyses the impact of government grants on labour demand using plant level data for manufacturing industry in Ireland. Our data consists of a large sample of plants and their complete grant history. We provide evidence that additional employment is created over and above the level that would have prevailed in the absence of grant payments. We also find differences in the employment response to subsidies between domestic and foreign-owned plants, with the former creating more additional jobs per euro of grant payment. Simple cost-benefit analysis reveals that a large part of the costs of grants appears to be recouped in additional wage streams under reasonable assumptions.     

Firm Size and Market Power in Carbonated Soft Drinks

Sutton (1998) offers us a simple way to model firm size distributions across differentiated products industries. We analyse the implications of this approach for company markups using a structural model for a specific industry. We incorporate the complexities of multi-product (brand) companies operating with different (strategic) configurations of product characteristics and stores to estimate brand markups, using Irish AC Nielsen retail data for Carbonated Soft Drinks. As a second step we estimate that market power does not increase in companies with higher market share, controlling for other factors. This challenges a traditional mind-set.     

The «control quota» component in the price of shares

This work has been sponsored by the Journées Internationale de l'Association Francaise de Finance (Strasbourg, Université L. Pasteur, June 12–14, 1980). The paper deals with the problem of a shareholder, that wishes to sell a portion of his quota and vants that the weakining of his position is adequately compensated.     

Asset substitutability and monetary policy: An alternative characterization

A distance function is defined for a simple portfolio choice problem and then used to express the impact on asset prices of a change in an asset stock as the sum of a substitution and a wealth effect. Substitutes and complements are defined with reference to qualtity rather than price changes. This method of characterizing asset substitutability leads to simpler and more easily interpreted results when analyzing monetary policy that does the standard approach which expresses asset price changes in terms of the price elasticities of the asset demand functions.     

A generalization of the Binomial distribution based on the dependence ratio

We propose a generalization of the Binomial distribution, called DR‐Binomial, which accommodates dependence among units through a model based on the dependence ratio (Ekholm et al., Biometrika, 82, 1995, 847). Properties of the DR‐Binomial are discussed, and the constraints on its parameter space are studied in detail. Likelihood‐based inference is presented, using both the joint and profile likelihoods; the usefulness of the DR‐Binomial in applications is illustrated on a real dataset displaying negative unit‐dependence, and hence under‐dispersion compared with the Binomial. Although the DR‐Binomial turns out to be a reparameterization of Altham's Additive‐Binomial and Kupper–Haseman's Correlated‐Binomial distribution, we believe its introduction is useful, both in terms of interpretability and mathematical tractability and in terms of generalizability to the Multinomial case.     

Replicating,validating, and reducing the length of the consumer perceived value scale

This research reports an assessment of Sweeney and Soutar's (2001) consumer perceived value (PERVAL) scale. The PERVAL scale contains four dimensions: quality, emotional, price, and social values. The present study develops and evaluates two short forms of the original 19-item PERVAL scale based on Sweeney and Soutar's (2001) original data and three other studies in two different countries. In comparison with the full scale, the short 12-item and 8-item forms have equally good dimensional properties and equivalent predictive validity. The discussion includes implications, both for research and for retail managers.
