NON-SEPARABLE CONSUMPTION-LABOR CHOICE AND THE INTERNATIONAL TRANSMISSION OF MONETARY POLICY SHOCKS: A NOTE

This paper derives in the model developed by Obstfeld and Rogoff (1995) a steady state that is stationary in the presence of monetary policy shocks. To this end, the impact of monetary policy shocks on the current account is shut off by assuming that the preferences of households exhibit a particular non-separability between consumption and labor supply.

The Interaction of Legal and Social Norm Enforcement

Although legal sanctions are often nondeterrent, we frequently observe compliance with “mild laws.” A possible explanation is that the incentives to comply are shaped not only by legal, but also by social sanctions. This paper employs a novel experimental approach to study the link between legal and social norm enforcement. We analyze whether the two institutions are complements or substitutes. Our results show that legal sanctions partially crowd out social norm enforcement. Mild laws nevertheless give scope for a potentially large, positive welfare effect, as a higher level of compliance is achieved at lower social enforcement costs.     

ANNOUNCEMENTS AND CREDIBILITY OF MONETARY POLICY

An infinitely repeated monetary policy game à la Barroand Gordon is considered. Before the game starts the governmentannounces a policy rule. If there is a slight probability thatgovernment is honest and a slight probability that the governmentmakes mistakes, then a sufficiently patient government willhave average loss close to its commitment loss in all sequentiallyrational equilibria of the infinitely repeated game.     

WHAT HAPPENS WHEN DEMAND IS ESTIMATED WITH A MISSPECIFIED MODEL?*

We conduct Monte Carlo experiments to investigate the biases of assuming a misspecified demand model. We study continuous models (linear, log‐linear and AIDS), and discrete choice models (logit) in the context of differentiated products and aggregate data. Estimating demand with the ‘wrong’ model yields varying degrees of bias in estimated elasticities, but the logit model can yield unbiased estimates for a certain size of the assumed market potential. Merger simulations confirm the key importance of market potential in logit estimation suggesting that a discrete choice model may be preferable even when the discreteness of the purchase decision is questionable.     

Capacity Cost and Capacity Allocation*

Abstract. Issues surrounding the allocation of sunk capacity costs to products are among the oldest in managerial accounting. On the one hand, such costs are generally deemed to be irrelevant, but on the other hand, actual accounting systems commonly make these allocations. This paper examines a decision maker who incurs costs to acquire capacity and then uses an opportunity cost to allocate that capacity among a sequence of product proposals. Under specified circumstances, the sunk cost of capacity is shown to approximate the optimal opportunity cost of capacity. As the number of product proposals grows, the expected opportunity loss from using a simple sunk cost based capacity allocation rule goes to zero. The model is extended to consider different types of products and a multiperiod setting. Résumé. Les questions qui entourent la répartition des coûts irrécupérables relatifs à la capacité entre les différents produits comptent parmi les plus vieux problèmes en comptabilité de gestion. D'une part, ces coûts sont généralement réputés n'être pas pertinents, tandis que d'autre part, en réalité, les systèmes de comptabilité assurent couramment ces répartitions. Les auteurs examinent le cas d'un décideur qui engage des frais pour acquérir une certaine capacité et utilise ensuite un coût d'option pour répartir cette capacité entre une série de projets de fabrication de produits. Dans des circonstances données, les auteurs démontrent que les coûts irrécupérables de la capacité acquise se rapprochent du coût d'option optimal de cette capacité. À mesure que croît le nombre de projets de fabrication de produits, la perte d'option prévue, si l'on utilise une règle de répartition simple de la capacité fondée sur les coûts irrécupérables, se rapproche de zéro. Le modèle est élargi de façon à englober différents types de produits et plusieurs périodes.     

The Cross‐Section of Credit Risk Premia and Equity Returns

We explore the link between a firm's stock returns and credit risk using a simple insight from structural models following Merton ( 1974 ): risk premia on equity and credit instruments are related because all claims on assets must earn the same compensation per unit of risk. Consistent with theory, we find that firms' stock returns increase with credit risk premia estimated from CDS spreads. Credit risk premia contain information not captured by physical or risk‐neutral default probabilities alone. This sheds new light on the “distress puzzle”—the lack of a positive relation between equity returns and default probabilities—reported in previous studies.     

How Do Firms Implement Impairment Tests of Goodwill?

This study seeks first to examine how firms implement impairment tests as required by IAS 36, and second, to explore factors which may explain why some firms are not entirely in compliance with IAS 36. It is based on a survey which includes 58 completed questionnaires representing 73% of the firms on the Copenhagen Stock Exchange that recognize goodwill on the balance sheet. The findings imply a variety in the application of IAS 36. Based on our analysis, it is difficult to determine whether this simply indicates that firms adopt an approach suited to their organizational and economic structures, or if it reveals that firms are uncertain as how to apply the standard. Our analysis further indicates inconsistencies in the implementation of IAS 36. This includes both how firms define a CGU and how they estimate the recoverable amount. Further, multivariate analysis reveals that the inconsistencies detected here are less likely in firms that systematize the procedures for impairment testing and use persons with considerable valuation experience. The findings should be of interest to a number of parties including firms, financial advisers, auditors, standard setters and users of financial statements.
