The welfare cost of unpriced heterogeneity in insurance markets
2016
We consider the welfare loss of unpriced heterogeneity in insurance markets, which results when private information or regulatory constraints prevent insurance companies to set premiums reflecting expected costs. We propose a methodology which uses survey data to measure this welfare loss. After identifying some “types” which determine expected risk and insurance demand, we derive the key factors defining the demand and cost functions in each market induced by these unobservable types. These are used to quantify the efficiency costs of unpriced heterogeneity. We apply our methods to the US Long-Term Care and Medigap insurance markets, where we find that unpriced heterogeneity causes substan…
Efectos de las fusiones bancarias en los resultados. El caso de las cajas rurales en España durante la primera mitad de la década de 2000
2010
ResumenDurante los últimos diez años se han producido numerosos episodios de fusiones entre cajas rurales españolas. El objetivo del trabajo es analizar el efecto que las fusiones entre cajas rurales llevadas a cabo durante la primera mitad de la década del 2000 han tenido sobre los niveles de rentabilidad, eficiencia y productividad y sobre el comportamiento estratégico de estas entidades. Para ello, se han seleccionado las fusiones realizadas durante el período considerado y se han analizado diferentes variables en comparación con la media del sector (grupo de control) para los cinco años anteriores y posteriores a la fusión. El estudio demuestra que las fusiones en las cajas rurales espa…
The Effect of Specialisation on Banks' Efficiency: An International Comparison
2006
Abstract This study analyses the effects of specialisation on the cost efficiency of a set of banking systems of the European Union over the period 1992–1998. Unlike in the established literature in which specialisation differences are not considered, in this paper cost inefficiencies are decomposed into two different components: the first is related to the inefficiency associated with the composition of specialisations in each banking system and the second is related to specific inefficiencies of banks within their specialisation. The results show the existence of high cost inefficiencies. However, the intra‐specialisation inefficiencies indicate that the inefficiencies of the European ban…
Weak efficiency of the cryptocurrency market: a market portfolio approach
2019
ABSTRACTCryptocurrencies have attracted the attention of many investors and policymakers given the increase in popularity of Bitcoin. In this context, we analyse the cryptocurrency market by means ...
Is external debt sustainable? A probabilistic approach
2020
Abstract We develop a probabilistic approach to measure a country's external debt sustainability. Using data on international investment position and balance of payments from the International Monetary Fund, we estimate a vector autoregressive model for 38 countries (11 developed and 27 developing). Using the estimated parameters, we perform a Monte Carlo simulation to compute the distribution of the capacity to repay for each country. A large portion of the projected distribution to the right of current debt is a warning indicator, signalling the need for devaluation. We provide simulations for each country. One scenario is where the discount factor is lower than 1. According to the litera…
¿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…
Wage leadership models: A country-by-country analysis of the EMU
2014
Abstract According to the theory of wage leadership, if there is free inter-sectoral labor mobility, changes in the level of the wage in the leading sector cause changes in the same direction in other sectors' wage. Moreover, since the traded sector (i.e. Industry) is affected by international competitive pressure, it should act as the leader, because this would be conducive to wage restraint. We apply a Vector Error Correction Model on four macro sectors (Industry, Services, Construction and the Public Sector) in ten EMU countries to test for wage leadership and wage adaptability. Our results show significant cross-country differences, with the Public Sector acting as the leader in Germany…
Testing the Acemoglu–Pischke model in Spain
2001
Abstract The Acemoglu–Pischke approach to training in imperfect labor markets predicts that wage compressions should shift incentives to invest in training from workers to firms. This will increase firm-sponsored general training when workers are unable to invest in training by themselves. Spain is on the top of the ranking of regulated labor markets. However, the training figures for Spain indicate a poor effect of highly compressed wage structure on firm-sponsored training.
Convergence in OECD countries: technical change, efficiency and productivity
1998
The aim of this study is to analyze labor productivity convergence in the countries of the OECD over the period 1965-90. A non-parametric frontier approach is used to calculate the Malmquist productivity index. By breaking it down, the contribution to the growth of labor productivity of technical progress, of changes in efficiency, and of the accumulation of inputs per worker are quantified. Unlike other studies, the results obtained show that technical change has worked against labor productivity convergence, since it has always been greater in the countries with higher labor productivity. El trabajo tiene como objetivo básico analizar la contribución de las distintas fuentes del crecimien…
Monopolistic competition and different wage setting systems
2010
In this paper, we present a disequilibrium unemployment model without labor market frictions and monopolistic competition in the goods market within an infinite horizon model of growth. We consider different wage setting systems and compare wages, the unemployment rate, and income per capita in the long-run at firm, sector, and national (centralized) levels. The aim of this paper is to determine under which conditions, the inverted-U hypothesis between unemployment and the degree of centralization of wage bargaining, reported by Calmfors and Driffill [Economic Policy, 6, 14¿61, 1988], is confirmed. Our analysis shows that a high degree of market power normally produces the inverted-U shape …
