Cross-country income mobility comparisons under panel attrition: the relevance of weighting schemes

This article aims to present an assessment of the effects of panel attrition on income mobility comparisons for some EU countries by using the European Community Household Panel (ECHP). There are different possibilities of correcting the attrition problem by means of alternative longitudinal weighting schemes. The sensitivity of mobility estimates to these attrition correction procedures is tested in this article. Our results show that ECHP attrition is characterized by a certain degree of selectivity but only affecting some variables and countries. Different probability models corroborate the existence of a certain nonrandom attrition. The model chosen to construct the longitudinal weights to correct attrition offers up rather different results than those obtained when Eurostat's longitudinal weights are used. Although attrition does not seem to have a great effect on aggregated mobility indicators, it does have a decisive effect on decomposition exercises. Our tests reveal certain sensitivity of income mobility measures to the weighting system used.     

Improving the absorptive capacity through unlearning context: an empirical investigation in hospital-in-the-home units

The Spanish healthcare system has undergone important changes, particularly in the development of new homecare services. In practice, however, results have been mixed. Some homecare services have been successful, but implementation failures are common and the intended patients are frequently reluctant to use the homecare services. A possible explanation for efficiency and effectiveness gaps of services provided by hospital-in-the-home units (HHUs) may relate to the advantages and disadvantages of the knowledge processes that these units highlight as a result of their different structural properties. This study examines the impact of an unlearning (forgetting) context on the HHU's ability to challenge basic beliefs and to implement processes that are explicitly or tacitly helpful in the reception of new ideas (absorptive capacity). These relationships are examined through an empirical investigation of 54 doctors and 62 nurses belonging to 44 HHUs. The results show that the unlearning context plays a key role in managing the tension between potential absorptive capacity and realized absorptive capacity.     

On the Measurement of Strength of Preference in Units of Money

We report an experimental study that aims to elicit monetary measures of strength of preference in choices involving pairs of risky prospects. Despite extensive testing to refine the instruments used, we find that these money measures are systematically biased upwards relative to subsequent binary choices. We discuss possible reasons for this bias and its broader implications.     

On the observational implications of taste-based discrimination in racial profiling

This paper contributes to a growing literature that attempts to determine whether disparities in police stops and searches of potential criminals of different races stem from taste-based discrimination. The key challenge in making this evaluation is that police officers have more information than the econometrician and thus racial disparities in police behavior may result from these unobservable factors rather than discrimination. We develop a general equilibrium model of police and potential criminal behavior that encompasses key models in the literature. We highlight the assumptions needed for existing methods of detecting racial discrimination to hold. In particular, we show that when there are increasing costs to search, existing tests for discrimination can give incorrect results. Given the potential importance of these costs, we then propose some alternate methods for detecting racial bias in police behavior.
