UNDERWRITING SPREADS AND REPUTATIONAL CAPITAL: AN ANALYSIS OF NEW CORPORATE SECURITIES

When entering a new security market, investment banks must establish their reputation. This is done through direct experience in the security market or through reputational capital established in existing security markets. I examine the effects of underwriters' market reputation in publicly underwritten offerings in forty-three financial innovations and find more significant entry barriers for less prestigious underwriters. An analysis of underwriting spreads reveals first-issue pricing advantages due to reputational capital. Unlike the more prestigious underwriters, the less prestigious underwriters reduce spreads upon first entry into each new security market to overcome their lack of market reputation.     

Reasonableness and Section 4 of the Employment Act 1980

This article explains the origins of s.4 of the Employment Act 1980 and assesses the place of this provision in the corpus of labour legislation enacted by the Conservative government since 1980. Its principal aim is to concentrate upon the concept of reasonableness which is central to the operation of the provision and to evaluate critically the role of the EAT and the industrial tribunals in interpreting it. Finally, the article seeks to assess the impact of the tribunaľs interpretation of s.4 on union admission and expulsion procedures.     

Intra-LATA toll elasticities

Regulatory commission hearings on intra-LATA toll competition have focused, for the purpose of revenue rebalancing, on the market elasticity of demand for intra-LATA toll service. This paper presents estimates of the intra-LATA toll elasticity based on a detailed model of residential customers' demand for short-haul service. The results are compared with those from other studies. The consensus of the studies indicates a residential elasticity of around -0.4.     

A Theory of Mutable and Immutable Characteristics: Their Impact on Allocation and Structural Positions

This article presents the global-mutable-immutable scheme. Globals are purely macro properties of societies, while immutables are purely micro properties of individuals. Mutables are the micro-macro bridging elements, having both an aggregated macro (distributional) form, as well as a micro form. The importance of this distinction for the analysis of norm, status and role is shown. The article concludes by showing how the configuration of globals, mutables and immutables affect the allocation of an individual into the five-dimensional mutable structure of his or her society at a given point in time.     

The asymmetry of judgemental confidence intervals in time series forecasting

In forecasting a time series, one may be asked to communicate the likely distribution of the future actual value, often expressed as a confidence interval. Whilst the accuracy (calibration) of these intervals has dominated most studies to date, this paper is concerned with other possible characteristics of the intervals. It reports a study in which the prevalence and determinants of the symmetry of judgemental confidence intervals in time series forecasting was examined. Most prior work has assumed that this interval is symmetrically placed around the forecast. However, this study shows that people generally estimate asymmetric confidence intervals where the forecast is not the midpoint of the estimated interval. Many of these intervals are grossly asymmetric. Results indicate that the placement of the forecast in relation to the last actual value of a time series is a major determinant of the direction and size of the asymmetry.     

A Brief Survey of Modern Optimization for Statisticians

Modern computational statistics is turning more and more to high‐dimensional optimization to handle the deluge of big data. Once a model is formulated, its parameters can be estimated by optimization. Because model parsimony is important, models routinely include non‐differentiable penalty terms such as the lasso. This sober reality complicates minimization and maximization. Our broad survey stresses a few important principles in algorithm design. Rather than view these principles in isolation, it is more productive to mix and match them. A few well‐chosen examples illustrate this point. Algorithm derivation is also emphasized, and theory is downplayed, particularly the abstractions of the convex calculus. Thus, our survey should be useful and accessible to a broad audience.     

Life-cycle patterns in male/female differences in job search

We investigate whether women search longer for a job than men and whether these differences change over the life cycle. Our empirical analysis exploits German register data on highly attached displaced workers. We apply duration models to analyze gender differences in job search taking into account observed and unobserved worker heterogeneity and censoring. Simple survival functions show that displaced women take longer to find a new job than comparable men. Disaggregation by age groups reveals that these differences are driven by differential behavior of women in their prime-childbearing years. There is no significant difference in job search duration among the very young and older workers. These differential outcomes remain even after we control for differences in human capital and when unobserved heterogeneity is incorporated into the model.
