A peculiar archaeology: Searching for Mr Giffen's behaviour

Abstract

It has been claimed that references to ‘Giffen behaviour’ constituted a single research project, driven by attempts to establish whether an initial ‘conjecture’ by Alfred Marshall had empirical validity. There is no stable basis for that claim because Marshall's discussion was contradictory and Robert Giffen rejected a key assumption made by Marshall. By the mid-1920s, discussion of an upward-sloping demand curve attached no particular significance to a Marshallian story. The formulation of the Irish famine Giffen exemplar by P.A. Samuelson illustrates how Giffen behaviour was stabilised as the single possible exception to the law of demand in the 1960s.     

Why do firms issue private equity repeatedly? On the motives and information content of multiple PIPE offerings

This study examines why private equity issues tend to be a repeated source of financing for public firms. We test the recent operational needs theory of public equity issuance within the context of repeated private equity issues. We find that repeated PIPE issuers burn through cash quickly and do not reach the standards of information transparency or profitability needed for a successful public equity offering. This has implications for investor composition and the market response to a PIPE. Initial PIPE offerings are characterized by substantial diversity in investor type. In successive transactions firms increasingly rely upon hedge funds, who extract greater price discounts and more often require cash flow rights as opposed to control rights. As firms select a path of repeated PIPEs to raise funds, successive issues become uninformative to the market. We conclude that, for small public firms, the same motive underlies public equity offerings and repeated private equity offerings—an acute need for cash.     

On dividends in the phase–type dual risk model

The dual risk model assumes that the surplus of a company decreases at a constant rate over time, and grows by means of upward jumps which occur at random times with random sizes. In the present work, we study the dual risk renewal model when the waiting times are phase-type distributed. Using the roots of the fundamental and the generalized Lundberg’s equations, we get expressions for the ruin probability and the Laplace transform of the time of ruin for an arbitrary single gain distribution. Then, we address the calculation of expected discounted future dividends particularly when the individual common gains follow a phase-type distribution. We further show that the optimal dividend barrier does not depend on the initial reserve. As far as the roots of the Lundberg equations and the time of ruin are concerned, we address the existing formulae in the corresponding Sparre-Andersen insurance risk model for the first hitting time, and we generalize them to cover also the situations where we have multiple roots. We do that working a new approach and technique, approach we also use for working the dividends, unlike others, it can be also applied for every situation.     

Comparing Interpersonal Comparisons in Utility Theory and Happiness Research

Social scientists are reluctant to make explicit interpersonal comparisons of well-being. However, implicit comparisons are made on a surprisingly regular basis. These comparisons are based on the wealth and the Kaldor–Hicks concept in utility theory and on self-reported well-being in happiness research. Taking a utilitarian stance, this paper tests the ethical foundations of both principles. While self-reported well-being serves as an acceptable proxy for utilitarian decision-making, the Kaldor–Hicks concept does not appear so. Implications for evaluating policies are outlined.

Assessing Recent Determinants of Borrowing Costs in Sub‐Saharan Africa

This study explores macroeconomic implications of the sovereign bond rush that has been taking place in sub‐Saharan Africa since 2006. The focus is on the sub‐Saharan sovereign bond yields as proxies for the region's ability to raise new funds on international markets. Despite the subcontinent's tour‐de‐force entrance to the international bond market, this paper reveals that recent (since early 2000s) borrowing in foreign currency is not without macroeconomic risk. Empirically this paper finds that sovereign bond yields are significantly influenced by global volatility, commodity prices and global liquidity—all factors that are out of the control of the sub‐Saharan economies in question. These findings suggest that portfolio repositioning by institutional investors prompted by improved growth prospects and implicit monetary policy tightening in the advanced economies or heightened risk perceptions, are likely to result in increased borrowing costs for the sub‐Saharan bond issuers and affect their ability to raise funds in international markets. Furthermore, a change in borrowing costs might lead to higher debt‐service costs and policy uncertainty, which in turn could lead to suboptimal investment levels and, ultimately, hinder economic development.     

Semi-parametric discrete choice measures of willingness to pay

A semi-parametric discrete choice method is proposed to recover welfare measures from individual choice data. The proposed method is compared with the traditional binary choice models in an application to measure benefits of recreation trips.     

Mediating effect of creativity between breadth of knowledge and innovation

Several previous studies have investigated the effects of creativity and knowledge on innovation, both of them being considered prerequisites of innovation. However, the relationship among the different variables can be confusing due to redundant causality. In this paper, we study the influence of the mediating effect of creativity between breadth of knowledge (diverse sources of knowledge) and innovation by developing a conceptual model, and then test it on the Spanish ceramic cluster of Castellón. Empirical findings show that creativity is the mechanism through which the different sources of knowledge influence innovation. The implications of these results in relation to creativity, knowledge and innovation theory and practices are discussed.
