A Short Overview of a Methodology for the Ex-Post Review of Merger Control Decisions

Summary  This paper is based on a study commissioned by the European Commission, in which we proposed a detailed methodological approach for the ex-post assessment of decisions reached by the European Commission in the field of merger control. The methodology focuses on how to establish whether the market structure arising from the decision is apt to protect consumer welfare better than the market structures that could have arisen from alternative decisions. It provides suggestions on how assess the impact of the decision relative to the possible counterfactuals and discusses the empirical techniques that can be used to perform this evaluation.     

Technological catch-up: Gradual diffusion of technology and convergence in the neoclassical growth model

In this paper, I study the effects of the international gradual transmission of technology on the convergence processes among countries. In this way, the international gradual diffusion of technology makes possible a greater potential improvement capacity to the less developed country in its technological level. When this hypothesis is included in the Solow-Swan growth models, the paper shows that the convergence hypothesis will now be maintained only in the growth rates since a gap in income levels will remain in the long run. That conditional convergence will be explained by two factors: the diminishing returns for cumulative factor and the gradual diffusion of technology. I will finish this paper with empirical evidence of these two factors explaining convergence.     

Israel’s open-secret trade

This paper uncovers and quantifies Israel’s exports to countries that ban trade with Israel. Israel exported a total of $6.4 billion worth of merchandise to boycott countries between 1962 and 2012, and most of this trade is illicit, i.e. not recorded by the importers. We find that electronic exports to Malaysia account for the lion’s share of this trade but it also includes a wide array of products from footwear to fruit and vegetables. Our estimates suggest Israel’s exports to these countries would be 10 times larger without the boycott. On top of providing further evidence on the unintended consequences of unilateral trade bans, this paper provides a case study on the role of politics in international trade.     

Efficiency evaluation in municipal services: an application to the street lighting service in Spain

Efficiency evaluation is very important in the municipal realm because of its impact on the people’s standard of living. However, in most cases the value of public output is hardly significant, and therefore measurement is necessarily limited to estimating technical efficiency, which is calculated using physical inputs and outputs. A major part of municipal services can be provided through different types of public management. This plurality of options lends greater relevance to the evaluation. This paper analyzes efficiency in the public street lighting service in Spanish towns, by means of DEA methodology, pursuing two objectives: to estimate the technical efficiency achieved and to discover whether differences in efficiency can be explained by the type of management, that has been chosen, whether public or private. The results of the analysis allow us to confirm that there is a significant relationship between the variables defined as inputs into the process and efficiency. However, the relationship is not very significant for the variables considered as outputs, in some cases. It was also detected that the factors defining the characteristics of the environment and the type of management, whether public or private, do not have a statistically significant impact on efficiency levels.

Asset allocation and portfolio performance: Evidence from university endowment funds

We use university endowment funds to study the relationship between asset allocation decisions and performance in multiple asset class portfolios. Although endowments differ substantially in asset class composition, policy portfolio returns and volatilities are remarkably similar across the sample. The risk-adjusted performance of the average endowment is negligible, but actively managed funds generate significantly larger alphas than passive ones. This is consistent with endowment managers exploiting their security selection abilities by over-weighting asset classes in which they have superior skills. Contrary to both theory and prevailing beliefs, asset allocation is not related to portfolio returns in the cross-section but does indirectly influence performance.     

Reporting Concerns About Earnings Quality: An Examination of Corporate Managers

Using an experiment with corporate financial managers (e.g., CFOs, controllers), we find that when red flags are present in the financial statements under their review, managers identify those red flags and, in turn, have greater concerns over earnings quality. In addition, when pressure to meet a financial target is high, managers are more concerned about earnings quality when red flags are present. We also document that when red flags are present, managers are more likely to report both internally to their CEO and, if their concerns are not resolved internally, externally to their auditor. Pressure to meet a financial target increases the likelihood managers report internally, but decreases their likelihood of reporting externally when red flags are present. Additional analyses document reporting differences between CFOs and controllers, and examine the important roles that short-term personal costs, job tenure, and a non-accounting background play in the ethical dilemma managers face when deciding whether to report externally.
