Emissions Taxation in Durable Goods Oligopoly

This paper examines the use of taxation to control external damage due to pollution when product durability is endogenously determined. A special form of the emissions function is also examined which is equivalent to an excise tax on output. The model indicates that many conventional results in the durability and taxation literature need not hold when durability is endogenously determined. The analysis shows durability may not be independent of industry structure nor will firms minimize their manufacturing costs of providing service. In addition, the second-best tax on imperfectly competitive firms is not necessarily less than the tax on a competitive firm with endogenous durability.     

International Evidence on Financial Derivatives Usage

Theory predicts that nonfinancial corporations might use derivatives to lower financial distress costs, coordinate cash flows with investment, or resolve agency conflicts between managers and owners. Using a new database, we find that traditional tests of these theories have little power to explain the determinants of corporate derivatives usage. Instead, we show that derivative usage is determined endogenously with other financial and operating decisions in ways that are intuitive but not related to specific theories for why firms hedge. For example, derivative usage helps determine the level and maturity of debt, dividend policy, holdings of liquid assets, and international operating hedging.     

Evaluating the bases of supplier segmentation: A review and taxonomy

A taxonomy of segmentation bases is presented which builds a multi-disciplinary approach to the categorization of suppliers. Supplier segmentation, from a purchasing perspective, still appears to be in the early stages of providing a coherent strategic intent behind supplier assessment. Whilst fragmentary in nature, current portfolio models are grouped into two principal taxonomic constructs of power and dependence and relational factors. In particular, the prevalent use of transaction cost economics (TCE) in portfolio modelling provides a foundation for purchasers to appraise risks from supplier opportunism. We augment existing approaches with reference to inter-organisational theory and the resource-based view to show different modes of inter-firm value creation that act as constituents of a strategic intent for segmentation. Our resulting taxonomy draws together a holistic view of supplier segmentation covering supply market conditions, product/service characteristics, supplier characteristics, buyer characteristics, and buyer-supplier relational factors.     

Imperfect Competition among Informed Traders

We analyze competition among informed traders in the continuous-time Kyle(1985) model, as Foster and Viswanathan (1996) do in discrete time. We explicitly describe the unique linear equilibrium when signals are imperfectly correlated and confirm the conjecture of Holden and Subrahmanyam (1992) that there is no linear equilibrium when signals are perfectly correlated. One result is that at some date, and at all dates thereafter, the market would have been more informationally efficient had there been a monopolist informed trader instead of competing traders. The relatively large amount of private information remaining near the end of trading causes the market to approach complete illiquidity.     

Bundesbank intervention effects through interest rate policy

This paper investigates the effects of the changes in the Bundesbank's discount and Lombard interest rates on the volatility of European Union country exchange rates relative to the German mark during 1987–93. The first year of the sample period contains the last major realignment in the ERM before its ‘breakdown’ in 1993. Using a parsimonious EGARCH model, we find that the conditional volatility of these exchange rates increased in response to interest rate changes, regardless of the rate change direction. This finding is in direct conflict with Bundesbank's public statements that indicate that its interest rate policy was designed to calm its foreign exchange markets.     

Inequality, inflation, and central bank independence

What can account for the different contemporaneous inflation experiences of various countries, and of the same country over time? We present an analysis of the determination of inflation from a political economy perspective. We document a positive correlation between income inequality and inflation and then present a theory of the determination of inflation outcomes in democratic societies that illustrates how greater inequality leads to greater inflation, owing to a desire by voters for wealth redistribution. We conclude by showing that democracies with more independent central banks tend to have better inflation outcomes for a given degree of inequality. JEL Classification E5, H0 Inégalité, inflation et l'indépendance de la banque centrale. Quels sont les facteurs qui pourraient expliquer les expériences inflationnistes tellement différentes des divers pays dans le passé récent, et l'expérience tellement différente d'un pays donné dans le temps? Les auteurs analysent ce problème de la détermination du taux d'inflation dans une perspective d'économie politique. Ils déterminent qu'il y a une corrélation positive entre l'inégalité et l'inflation, et présentent une théorie de la détermination de l'inflation dans les sociétés démocratiques qui montre comment une inégalité plus grande entraîne une inflation plus grande à cause du désir des électeurs de demander une redistribution de la richesse. Le mémoire montre en terminant que les démocraties e´quipées de banques centrales plus indépendantes tendent à avoir de meilleurs résultats en terme d'inflation pour un degré d'inégalité donné.     

Audit committee activity and agency costs

Menon and Williams indicate that many United States (US) over-the-counter (OTC) firms which form audit committees appear not to rely on them (cf. Menon, K., Williams, J.D. 1994. Journal of Accounting and Public Policy, 13(2), 121–139). Reliance on audit committees appears to depend upon board composition, while audit committee activity is associated with firm size. In this paper, we compare the US experience and evidence on audit committees and monitoring with the position in the United Kingdom (UK), where there has been a steady growth in the number of major companies voluntarily forming audit committees over the last 15 years (Collier, P.A. 1996. Accounting, Business and Financial History 6(2), 121–140). We contend that the dataset is best analyzed using the Heckman procedure (cf. Heckman, J.A. 1979. Econometrica 47(1), 153–161) which captures the two stages of the decision on audit committee activity.Our results show little support from the UK data for the findings of Menon and Williams (cf. Menon and Williams, 1994. Journal of Accounting and Public Policy 13(2), 121–139). However, consistent with their agency theoretic perspective of monitoring, we found that high quality (Big Six) auditors, and to some degree leverage have a positive relationship with audit committee activity. Contrary to an agency theoretic expectation, we found that audit committee activity is reduced in firms that combine the role of chairman and chief executive. On the basis of this result we explored the impact of insiders (executive directors) and found that their presence on an audit committee had a significant negative impact on audit committee activity. This result suggests that the emphasis placed by the US Securities and Exchange Commission (SEC) (Staff Report on Corporate Accountability, US Government Printing Office, Washington, DC, 1980, p. 491) and the Cadbury Committee (Committee on the Financial Aspects of Corporate Governance. 1992. Report of the Committee on the Financial Aspects of Corporate Governance. Gee, London) on the independence of audit committee members may be well founded.The reduction in audit committee activity that arises from the combination of the role of chairman and chief executive officer, and the presence of insiders on the audit committee, has important policy implications. Indeed, in the UK, both practices are the subject of recommendations in the Hampel Committee report Hampel Committee 1998. Committee on Corporate Governance. Gee, London.     

The Effect of Labor Market Demand on U.S. CEO Pay Since 1980

This paper shows that the rise in U.S. chief executive officer (CEO) pay from 1980 to 2003 is only partially explained by competition for profit‐producing talent in the labor market. This conclusion is obtained by removing unintended data biases from tests of the only theoretical model in the literature that relates labor market competition (measured by large firm size) to CEO pay level. When the biases are removed or minimized, no more than 33% of the 600+ percentage rise in large‐firm CEO pay since 1980 is explained by a corresponding increase in large firm size.     

Understanding the Backus–Smith puzzle: It's the (nominal) exchange rate,stupid

Backus, Kehoe and Kydland (BKK 1992) demonstrated that if international capital markets are complete, consumption growth correlations across countries should be higher than their corresponding output growth correlations. In stark contrast to the theory, however, in actual data the consumption growth correlation is lower than the output growth correlation. By assuming trade imperfections due to non-traded goods, Backus, D.K., Smith, G.W. [1993 Consumption and real exchange rates in dynamic economies with non-traded goods. Journal of International Economics 35(3–4), 297–316] showed that there is an additional impediment at work that can lower the consumption growth correlation. While their argument was successful in partially explaining the puzzlingly low cross country correlation of consumption growth rates, it contributed to generating another puzzle because the data forcefully show that consumption growth is negatively correlated with the real exchange rate, which is also a violation of the theory. Using data for OECD countries, we decompose real exchange rate growth into its nominal exchange rate growth and inflation differential components, and find that nominal exchange rate movements are the main source for the Backus-Smith puzzle. We demonstrate the robustness of this finding by examining sub-samples of the data, by allowing for imperfect risk sharing due to ‘rule of thumb’ consumers, and by examining intranational data across the U.S. states where the nominal exchange rate is fixed.
