Heterogeneous information and trade policy

Protectionism enjoys surprising popular support, in spite of deadweight losses. At thesame time, trade barriers appear to decline with public information about protection.This paper develops an electoral model with heterogeneously informed voters whichexplains both facts and predicts the pattern of trade policy across industries. In themodel, each agent endogenously acquires more information about his sector of employment. As a result, voters support protectionism, because they learn more about thetrade barriers that help them as producers than those that hurt them as consumers.In equilibrium, asymmetric information induces a universal protectionist bias. Thestructure of protection is Pareto inefficient, in contrast to existing models. The modelpredicts a Dracula effect: trade policy for a sector is less protectionist when there ismore public information about it. Using a measure of newspaper coverage across industries, I find that cross-sector evidence from the United States bears out my theoreticalpredictions.

A leverage theory of reputation building with co-branding: Complementarity in reputation building

We present a leverage theory of reputation building with co-branding. We showthat under certain conditions, co-branding that links unknown firms in a new sectorwith established firms in a mature sector allows the unknown firms to signal a highproduct quality and establish their own reputation. We compare this situationwith a benchmark in which both sectors are new and firms signal their qualityonly with prices. We investigate how this comparison is affected by the nature ofthe technology linking the two sectors and a cross-sector inference problem thatconsumers might face in identifying the true cause of product failure. We find thatco-branding facilitates the process in which a Þrm in the new sector to signal itsproduct quality only if the co-branding sectors produce complementary inputs andconsumers face a cross-sector inference problem. We apply our insight to economicsof superstars, multinational firms and co-authorship.

Quality assurance mechanisms in agrifood: The case of the Spanish fresh meat sector

The largest fresh meat brand names in Spain are analyzed here to studyhow quality is signaled in agribusiness and how the underlying quality-assurance organizations work. Results show, first, that organizationalform varies according to the specialization of the brand name.Publicly-controlled brand names are grounded on market contracting withindividual producers, providing stronger incentives. In contrast,private brands rely more on hierarchy, taking advantage of itssuperiority in solving specific coordination problems. Second, theseemingly redundant coexistence of several quality indicators for agiven product is explained in efficiency terms. Multiple brands areshown to be complementary, given their specialization in guaranteeingdifferent attributes of the product.

Velocity cross-correlations and atomic momentum transfer in simple liquids with different potential cores

Time correlation functions between the velocity of a tagged particle and velocities of particles within specified ranges of initial separations have been obtained by molecular dynamics simulation. These correlation functions have allowed us to analyze the momentum transfer between particles in different coordination shells. Two simple liquids at very different densities and two purely repulsive potentials with very different softnesses have been considered. The longitudinal correlations, which are the velocity cross-correlations along the initial direction defined by the centers of two given particles, have been calculated separately. It has been proven that these correlations should be attributed to particles both in front of and behind the central one. As with propagating longitudinal modes, they are strongly dependent on the softness of the potential core. Some characteristic features of the velocity correlation functions after the initial rise should be related to nonlongitudinal correlations. It has been shown that velocity cross-correlations between distinct particles cannot only be attributed to the direct interactions among particles, but also to the motions induced by the movement of a tagged particle on their neighbors.

Cross-country differences in disclosure quality: a study of fair value disclosures by european real estate companies

Companies are under IAS 40 required to report fair values of investment properties on the balance sheet or to disclose them in the notes. The standard requires also that companies have to disclose the methods and significant assumptions applied in determining fair values of investment properties. However, IAS 40 does not include any illustrative examples or other guidance on how to apply the disclosure requirements. We use a sample with publicly traded companies from the real estate sector in the EU. We find that a majority of the companies use income based methods for the measurement of fair values but there are considerable cross-country variations in the level of disclosures about the assumptions used in determining fair values. More specifically, we find that Scandinavian and German origin companies disclose more than French and English origin companies. We also test whether disclosure quality is associated with enforcement quality measured with the “Rule of Law” index according to Kaufmann et al. (2010), and associated with a secrecy- versus transparency-measure based on Gray (1988). We find a positive association between disclosure and earnings quality and a negative association with secrecy.

A global view of cross-border migration

This paper evaluates the global welfare impact of observed levels of migration using a quantitativemulti-sector model of the world economy calibrated to aggregate and firm-level data.Our framework features cross-country labor productivity differences, international trade, remittances,and a heterogeneous workforce. We compare welfare under the observed levels ofmigration to a no-migration counterfactual. In the long run, natives in countries that receiveda lot of migration -such as Canada or Australia- are better o due to greater product varietyavailable in consumption and as intermediate inputs. In the short run the impact of migrationon average welfare in these countries is close to zero, while the skilled and unskilled nativestend to experience welfare changes of opposite signs. The remaining natives in countries withlarge emigration flows -such as Jamaica or El Salvador- are also better off due to migration,but for a different reason: remittances. The welfare impact of observed levels of migration issubstantial, at about 5 to 10% for the main receiving countries and about 10% in countries withlarge incoming remittances. Our results are robust to accounting for imperfect transferabilityof skills, selection into migration, and imperfect substitution between natives and immigrants.

Innovación tecnológica y resultado exportador: un análisis empírico aplicado al sector textil-confección español

En los últimos años, la relación entre tecnología y resultado exportador ha sido objeto de algunos estudios centrados en explicar la relación existente entre los distintos indicadores de las actividades tecnológicas y la performance internacional de las empresas. Sin embargo, la mayoría de las investigaciones centradas en este tema tienden a aproximar la estrategia innovadora de una empresa a partir de sus gastos en actividades de I+D cuando, en realidad, el concepto de innovación tecnológica podría resultar más amplio que la mera realización formal de actividades de I+D. En este trabajo en primer lugar se identifican aquellos factores que aproximan, de una forma más exhaustiva, las actividades de innovación tecnológica que realiza una empresa y, en segundo lugar, se averiguará su relación con el resultado exportador de la misma. Los resultados que se obtienen son satisfactorios ya que demuestran que la probabilidad y la intensidad exportadora de las empresas españolas del sector textil-confección dependen no sólo de sus inversiones en I+D, sino también de otras variables vinculadas a su estrategia innovadora.

Un modelo de predicción de la insolvencia empresarial aplicado al sector téxtil y confección de Barcelona (1994-1997)

En los últimos 30 años la proliferación de modelos cuantitativos de predicción de la insolvencia empresarial en la literatura contable y financiera ha despertado un gran interés entre los especialistas e investigadores de la materia. Lo que en un principio fueron unos modelos elaborados con un único objetivo, han derivado en una fuente de investigación constante En este documento se formula un modelo de predicción de la insolvencia a través de la combinación de diferentes variables cuantitativas extraídas de los estados contables de una muestra de empresas para los años 1994-1997. A través de un procedimiento por etapas se selecciona e interpreta cuáles son las más relevantes en cuanto a aportación de información. Así mismo se comparan dos procedimientos estadísticos que se uitilizan en este tipo de investigaciones: la regresión logística y el análisis discriminante múltiple. Llegados a este punto, se compara qué tipo de selección de variables alcanza mejores resultados.

Modelo para la idenfiticación de grupos estratégicos basado en el análisis envolvente de datos: aplicación al sector bancario español

Este trabajo explora la formación de grupos estratégicos en el Sector Bancario Español, a partir de una definición alternativa de grupo estratégico (GE). Un GE se define como un conjunto de empresas capaces de responder del mismo modo a perturbaciones. La capacidad de respuesta, o capacidad de adaptar la estrategia competitiva, se define a partir de las relaciones marginales (RM) entre las variables estratégicas (la pendiente de la frontera en un punto), y sirve de base para examinar la presencia de barreras a la movilidad. El Análisis Envolvente de Datos (DEA) es la herramienta utilizada para el cómputo de las RM, aunque su uso genera dos problemas que son solucionados en este trabajo; la multiplicidad de RM para las empresas situadas en la frontera (líderes estratégicos), y la imposibilidad de encontrar RM para las empresas situadas por debajo de la misma (seguidores estratégicos).

Sobre los orígenes de la industrialización en el sector alimentario: Cataluña, 1880-1935

Hoy en día las industrias alimentarias ocupan un lugar destacado en la reproducción de la actividad económica. Además de centralizar la elaboración de aquellos productos y articular al conjunto del sector agroalimentario, aquellas industrias condicionan aspectos importantes de las políticas económicas nacionales y, estrechamente conectadas con las nuevas empresas biotecnológicas, configuran una de las líneas de actividad más innovadoras. En el caso de la historiografía española, las aportaciones realizadas hasta ahora han sido sobre todo de tipo sectorial y no han alterado demasiado las interpretaciones tradicionales. Como resultado de estos trabajos podemos concluir, por tanto, que en el momento actual conocemos relativamente bien la evolución de las principales industrias alimentarias en España desde el siglo XIX, pero que todavía no hemos integrado los resultados alcanzados en un nuevo marco interpretativo. En el presente artículo discutiré inicialmente estos planteamientos y destacaré, a partir de las investigaciones realizadas, aquellos aspectos de las nuevas propuestas interpretativas que me parecen más sugerentes. Seguidamente aplicaré estas propuestas al caso español, tomando como referencia el desarrollo que experimentaron diversas industrias alimentarias en Cataluña entre la segunda mitad del siglo XIX y la década de 1930.

Observability and overcoming coordination failure in organizations

Many organizations suffer poor performance because its members fail to coordinate on efficient patterns of behavior. In previous research, we have shown that financial incentives can be used to find a way out of such performance traps. Here we examine the sensitivity of this result to the ability of people to observe others' choices. Our experiments are set in a corporate environment where subjects' payoffs depend on coordinating at high effort levels; the underlying game being played repeatedly by the employees of an experimental firm is a weak-link game. Treatments vary along two dimensions. First, subjects either start with low financial incentives for coordination, which typically leads to coordination failure, and then are switched to higher incentives or start with high incentives, which typically yield effective coordination, and are switched to low incentives. Second, as the key treatment variable, subjects either observe the effort levels chosen by all employees in their experimenta

A change would do you good . . . An experimental study on how to overcome coordination failure in organizations

Many organizations suffer poor performance because individuals within the organization fail to coordinate on efficient patterns of behavior. Using controlled laboratory experiments, we study how financial incentives can be used to find a way out of such performance traps. Our experiments are set in a corporate environment where subjects' payoffs depend on coordinating at high effort levels; the underlying game being played repeatedly by employees is a weak-link game. In an initial phase, the benefits of coordination are low relative to the cost of increased effort. Play in this initial phase typically converges to an inefficient outcome with employees failing to coordinate at high effort levels. The experimental design then explores the effects of varying the financial incentives to coordinate at a higher effort level. We find that an increase in the benefits of coordination leads to improved coordination, but, surprisingly, large increases have no more impact than small increases. Once subj

Cambio ocupacional en los servicios financieros: nuevos requerimientos laborales ante la transformación del sector

El presente estudio relaciona la evolución de los servicios financieros y su entorno competitivo con la transformación de las características del ocupado tipo en el sector. Para ello dispone tres modelos de elección discreta binomial que estiman el perfil diferencial de la ocupación en los servicios financieros con respecto al conjunto de los servicios. El sistema financiero español se caracteriza por un elevado grado de asalarización del empleo y presenta requerimientos de factor trabajo crecientemente sesgados hacia una mano de obra con elevada formación. Ello responde a un nuevo entorno, más competitivo y liberalizado, en el que la institución financiera debe aproximarse al cliente. El trabajador asume progresivamente, por tanto, funciones comerciales en detrimento de las tareas de carácter administrativo tradicionales en la banca. En este contexto, el nivel educativo es utilizado más bien como señal de competencias que como repertorio de conocimientos adquiridos.

Relating severe poverty and chronic poverty

The severely poor are very poor since their consumption is far below the absolute poverty line, and the chronically poor are very poor since their consumption persists for long periods below the absolute poverty line. A combination of chronic poverty and severe poverty (CSP) must represent the very worst instance of poverty. Yet the exercise in this paper of asking simple questions about CSP shows large research gaps. Quantified statements on CSP at the country level can be made for just 14 countries, and at the household level in just six countries. This data suggests a positive correlation between severe poverty and chronic poverty, both at the country level and the household level. Understanding the CSP relationship – whether it is strong, where it arises, what causes it – may improve our explanation of observed cross-country variation in the elasticity between macroeconomic growth and poverty reduction, and why within countries, some households take better advantage of opportunities afforded by macroeconomic growth. Some limited data suggests similarity in socioeconomic characteristics of the severe poor and the chronic poor in terms of location, household size, gender, education and economic sector of work. Of concern is that microlongitudinal datasets drop large proportions of their base year samples, and how this affects our understanding of CSP is not well evaluated. On causal mechanisms, evidence suggests that CSP may be caused by parental CSP (i.e. an intergenerational CSP cycle) and in households not previously poor, CSP may be caused by a morbidity cycle.

Public enterprise reforms and efficiency in regulated environments: the case of the postal sector

Purpose - This paper focuses on analyzing the effect that public reforms have on the efficiency of state-owned enterprises in regulated environments. Design/methodology/approach - The research is focused in the postal sector where public and private companies must obey a legal framework related to provide a universal service. The analysis is carried out using a panel of 7 European postal operators for the period 1997-2003. The activity analyzed was the letter mail division; we take as key variable the unit cost of a letter and use a translog cost function where as independent variables we include traffic levels, labor cost per employee, quality and availability of the service as well as the type of ownership (public or private). Additionally, in a second stage the geographical differences among countries are considered. Findings - Results indicate that postal operators that experienced organizational changes without being privatized, such as the Spanish and Greek operators, do not have higher unit costs than privatized postal operators like the one of Germany and the Netherlands. Moreover, we find that in all cases the operator of Ireland appear to be the most efficient. In this case restructuring process has been carried out giving an important leadership role to workers. This suggests us that labor culture could be a key variable to study when analyzing reform processes in public enterprises. Originality/value - Our findings show that in a regulated environment like in the postal sector, public and private companies can obtain similar efficiency levels in term of unit costs.
