Econometric modelling in finance and risk management: An overview

This paper gives an overview about the sixteen papers included in this special issue. The papers in this special issue cover a wide range of topics. Such topics include discussing a class of tests for correlation, estimation of realized volatility, modeling time series and continuous-time models with long-range dependence, estimation and specification testing of time series models, estimation in a factor model with high-dimensional problems, finite-sample examination of quasi-maximum likelihood estimation in an autoregressive conditional duration model, and estimation in a dynamic additive quantile model.     

Relocation Opportunities and Mortgage Default

This paper presents a theoretical model of residential mortgage default when borrowers face beneficial as well as costly relocation opportunities. It amplifies and extends previous work by providing explicit conditions leading to default. The model also establishes when a borrower's relocation decision and default decision are dependent and when they are not.
A central result is that there is a range of book equity wherein the decision to default is not determined solely by the current level of equity or the borrower's ability to continue the mortgage payments. Rather, various costs and benefits, both tangible and intangible, enter into the decision. Specific conditions are identified that lead to relocation without default, default and relocation, and no default or relocation. The effects of changes in the variables upon default probability are presented.
Assuming that the borrower does not wish to retain ownership in the property, the model also predicts whether an individual borrower will choose prepayment or default when a relocation is made. The choice depends on the value of the relocation opportunity faced by the borrower, as well as financial variables such as house value, mortgage balance, and transaction costs. This finding suggests that existing empirical analyses of default may have omitted explanatory variables.     

Psychometric Properties of the Reidenbach–Robin Multidimensional Ethics Scale

The factor structure of the Multidimensional Ethics Scale (MES; Reidenbach and Robin: 1988, Journal of Business Ethics 7, 871–879; 1990, Journal of Business Ethics 9, 639–653) was examined for the 8-item short form (N = 328) and the original 30-item pool (N = 260). The objectives of the study were: to verify the dimensionality of the MES; to increase the amount of true cross-scenario variance through the use of 18 scenarios varying in moral intensity (Jones: 1991, Academy of Management Review 16, 366–395); and, to examine the items for measurement precision using item-response theory (IRT) methods. Results of confirmatory and exploratory factor analysis failed to conclusively support the hypothesized 3- (short form) or 5-factor (long form) structure; both instruments were instead dominated by a general factor. Item response theory analyses using Samejima’s (1969, Psychometrika Monograph Supplement 34, (4, Pt. 2)) graded response model revealed that many items in the 30-item pool performed very well, and suggested that a different collection of items be used to form a short-form version of the MES. Our proposed 10-item instrument includes more discriminating items than the 8-item version, and has the added advantage of including two items from each of the five ethical philosophies represented in the original 30-item pool.

Two-Stage Acquisitions, Free-Riding, and Corporate Control

This study examines two-stage acquisitions, focusing upon first- and second-stage excess returns for both acquired and acquiring firms, and analyzing the relation between acquisition returns and ownership interest. The evidence suggests that target firm shareholders do not free-ride. Evidence is also provided indicating that premiums are paid by the majority holder to acquire a remaining minority interest.     

Efficiency wages and income taxes

The paper was written during a visit at the Ludwig-Maximilian-University of Munich in the summer of 1988. The hospitality of this institution, as well as the financial support from a Ruhrgas Scholarship under the West German Norwegian Scholarship Scheme, is gratefully acknowledged. Participants at various seminars have given useful comments and criticism. I am also grateful to two anonymous referees for their comments to an earlier version of the paper.     

Global monetary policy under a dollar standard

This paper derives an optimal monetary policy in a world with a dollar standard, defined as an environment in which all traded goods prices are set in US dollars, so that exchange rate pass-through into the US price level is zero. We show that the US is essentially indifferent to exchange rate volatility, while the rest of the world places a high weight on exchange rate volatility. In a Nash equilibrium of the monetary policy game, US preferences dominate; the equilibrium is identical to one where the US alone chooses world monetary policy. Despite this, we find surprisingly that the US loses from the dollar's role as an international currency, since the absence of exchange rate pass-through leads to inefficient expenditure allocations within the US. Finally, we derive the conditions for a dollar standard to exist.
