A nonparametric analysis of multi-product oligopolies

We develop revealed preference tests for models of multi-product oligopoly, building on the work in Carvajal et al. (Econometrica 81(6):2351–2379, 2013). We analyze a Cournot model with multiple goods and show that it has testable restrictions when at least one good is produced by two or more firms. We also develop a revealed preference test for Bertrand oligopoly in a setting where each firm produces a single differentiated good, and these goods are potentially substitutes for each other. Our tests require qualitative assumptions on the shape of the demand curves and (in the Bertrand case) their evolution across observations, but they do not rely on the estimation of market demand.     

Earnings benchmark hierarchy

We examine the hierarchy of earnings benchmarks in Australia. Our results demonstrate a disconnect between the actions managers appear to take and the market reaction to firms exceeding or just missing earnings benchmarks. The actions of managers appear consistent with them acting in a manner to avoid making losses and earnings decreases. On the other hand, the market reacts in a manner where the analysts’ earnings forecast is at the top of the earnings benchmark hierarchy. However, for firms without analyst coverage, the reporting of positive earnings is the predominant earnings benchmark.     

No-arbitrage, state prices and trade in thin financial markets

We examine how non-competitiveness in financial markets affects the choice of asset portfolios and the determination of equilibrium prices. In our model, potential arbitrage is conducted by a few highly specialized institutional investors who recognize and estimate the impact of their trades on financial prices. We apply a model of economic equilibrium, based on Weretka (, 2007a), in which price effects are determined endogenously as part of the equilibrium concept. For the case in which markets allow for perfect insurance, we argue that the principle of no-arbitrage asset pricing is consistent with non-competitive behavior of the arbitragers and extend the fundamental theorem of asset pricing to the non-competitive setting.     

Developing ASEAN‐5 bond markets: what needs to be done?

This paper examines development challenges facing bond markets in the ASEAN‐5 (Indonesia, Malaysia, Philippines, Singapore, and Thailand). It first assesses their level of development, finding that bond market frameworks—that is, the quality of the physical infrastructure, monitoring, and regulation—compare favourably with those in other emerging markets. The paper then considers possible further enhancements, including changes in disclosure practices as well as reforms of ratings agencies, central bank liquidity management, and taxation. It also considers steps to develop derivatives markets, which in some countries remain quite small. Finally, the article draws lessons from the global financial crisis in developed markets for the future development of ASEAN‐5 markets.     

Economic grounds for affirmative action: The evidence on architects and engineers in South Florida

Using data developed for, and presented to, the US District Court, this study evaluates the performance of women-, African-American-, and Hispanic-owned firms vis-à-vis firms owned by neither women nor minorities in three different South Florida markets: architecture, structural engineering, and civil engineering. After controlling for the influence of experience, size, and location, three of the most commonly used determinants of firms' earnings, the empirical results suggest that the three markets do not convert firms' characteristics into economic outcomes in the same manner for women and Hispanic owners as for owners who are neither women nor minorities.     

How to support the management of intangibles

The main objective of this work is the application of the concept of intellectual capital to management for business development and innovation. Concretely, we propose strengthening the ‘Intellectus’ model of intellectual capital by combining it with a multicriteria methodology called the ‘analytic hierarchy process’. The proposed methodology seeks to facilitate decision making by managers in focusing actions and resources to innovate and improve the value of their services to their clients. In particular, an application was made to the banking service sector in Chile, to identify the intangibles of greater importance in loyalty-building of clients. We identified technological capital, human capital and business capital as the intangibles with the highest priorities.     

Mind the gap: line managers as effective or non‐effective talent spotters

Due to the centrality of line managers’ role in the talent identification process, this qualitative study aims to determine what effective and non‐effective talent spotters do differently from one another in relation with an ‘ideal’ talent identification model offered by the literature. A double‐blind design was applied to the sample designated by the Corporate Talent Management Director of a Latin American multinational firm. 20 senior and middle managers, some effective and some others non‐effective, who work in different countries, participated in the study. Findings show that effective talent spotters perform three key stages of the talent identification model and they do it extremely well: differentiation of potential from performance, matching process and design of developmental challenges. The clear differentiation of potential from performance constitutes the crucial stage since a fuzzy differentiation taints the following stages. Not only is it necessary to perform these key stages but they should be executed in line with the principles of the talent management literature. Recommendations for practice, including specific guidelines for Talent Managers are proposed.
