Selection by committee: Anonymity and gratitude
2018
Abstract What kind of candidate is selected into a job when the principal has to appoint a committee to measure the candidates’ ability and select a winner? We find that if the committee takes into account the candidate’s gratitude towards them, a candidate with less than first best ability will be selected. A relevant exception may occur if the first best is the overall best candidate. First best selection is always achieved if the committee is anonymous to the candidates. If the committee is not detached enough from the candidates then delegation fares even worse than random selection.
The timeline of trading frictions in the European carbon market
2012
We evaluate the quality of prices of EU-ETS, the most active European derivative market for greenhouse gas emissions allowances (EUAs). So far, this market has had two phases, a trial phase (from 2005 to 2007) and a commitment phase (from 2008 to 2012). The true value of a trial-phase EUA at the beginning of 2008 was inevitably zero because it could not be used in the commitment phase to cover emission targets. However, continued rumors of over-allocation of EUAs led to an early collapse of the market by May 2007. We study whether this market breakdown and the subsequent outbreak of the international financial crisis had a persistent effect on the quality of the commitment phase. We provide…
Variable selection in the analysis of energy consumption-growth nexus
2015
There is abundant empirical literature that focuses on whether energy consumption is a critical driver of economic growth. The evolution of this literature has largely consisted of attempts to solve the problems and answer the criticisms arising from earlier studies. One of the most common criticisms is that previous work concentrates on the bivariate relationship, energy consumption–economic growth. Many authors try to overcome this critique using control variables. However, the choice of these variables has been ad hoc, made according to the subjective economic rationale of the authors. Our contribution to this literature is to apply a robust probabilistic model to select the explanatory …
Are private schools more efficient than public schools ? Evidence from Tanzania
2001
International audience; Beginning in the mid-1980s, there has been an explosive growth of private secondary schools in Tanzania. By easing constraints on private operators, the government has clearly found an effective way in the context of right public budget constraints to cope with the excess demand for this level of schooling. But has the policy also led to efficient operations in terms of student learning ? In this paper, we attempt to shed light on this issue by comparing the efficiency of four types of schools that make up the majority of schools in the country : Government and Community schools in the public sector, and Chirstian and Wazazi schools in the private sector. Using longi…
Selection bias, incentivi alle imprese e sviluppo locale: Una valutazione ex-post
2015
Questo lavoro si concentra sulla valutazione di un programma di aiuti alle imprese facente parte di un piu vasto programma per lo sviluppo locale realizzato in Italia durante il ciclo di programmazione comunitaria 2000-2006. Esso costituisce un approfondimento di una precedente analisi (Cusimano, Mazzola, 2014) di valutazione ex-post degli effetti dei regimi di aiuto previsti nell’ambito dei progetti integrati territoriali (pit), e mira ad identificare l’eventuale presenza di distorsione da selezione (selection bias) nella quantificazione dell’efficacia della politica. Mediante un’analisi empirica effettuata per mezzo di diverse metodologie basate sul propensity score matching (psm) viene m…
¿SE PUEDE MEDIR LA NEGOCIACIÓN INFORMADA?: UNA REVISIÓN DE LA METODOLOGÍA BASADA EN LAS COVARIANZAS DE LAS SERIES DE PRECIOS
2009
RESUMENEl desarrollo en los modelos teóricos de microestructura ha motivado la aparición de un grupo de trabajos encaminado al estudio empírico de los costes de transacción y sus componentes dada la importancia que han tenido los mismos en el estudio del funcionamiento de los mercados y la comparación entre éstos así como sus numerosas aplicaciones en campos afines (finanzas corporativas, eficiencia de los mercados, etc.). Por otra parte, la contrastación empírica de los distintos modelos establecidos muestra resultados claramente dispares. Por ello, el objetivo de nuestro trabajo es analizar con detalle y en conjunto dichos modelos centrándonos en un grupo con características muy similares…
Why Finnish polytechnics reject top applicants
2019
I use a panel of higher education clearinghouse data to study the centralized assignment of applicants to Finnish polytechnics. Many top applicants remain completely unassigned each year. The same applicants' future applications reveal that many of them should have been admitted to a different program immediately. The application system, however, discourages applicants from applying to multiple programs within the same year, while at the same time leaving them in the dark on the set of programs willing to admit them. Improvements to the application system have the potential to substantially reduce reapplications, thereby shortening long queues into Finnish higher education. peerReviewed
Crowding-out effect and sorting in competitive labour markets with motivated workers
2018
ABSTRACTThis article makes a contribution to the economics literature by inducing proper self-selection into contracts based on workers’ motivation. The novelty of our results is that it points out the alternative potential role of the crowding-out effect to separate workers based on their motivation.
Does Firm Size Affect Self-selection and Learning-by-Exporting?
2010
The trade literature has long discussed the existence of some benefits attributed to exporting, among others, the improvement of firm productivity. This paper examines whether firm size plays a role in this supposedly favourable relationship between exporting and total factor productivity (TFP). To examine this, we investigate, separately for large and small firms, whether firms starting to export perform better ex ante (self-selection) than non-exporting firms and, conditional on this fact, if they are also more productive ex post (learning-by-exporting). With this purpose, we use both stochastic dominance and matching techniques. The dataset is a representative sample of Spanish manufactu…
WEIGHTED-AVERAGE LEAST SQUARES (WALS): A SURVEY
2014
Model averaging has become a popular method of estimation, following increasing evidence that model selection and estimation should be treated as one joint procedure. Weighted- average least squares (WALS) is a recent model-average approach, which takes an intermediate position between frequentist and Bayesian methods, allows a credible treatment of ignorance, and is extremely fast to compute. We review the theory of WALS and discuss extensions and applications.
