An evaluation of contingent immunization

This paper tests the effectiveness of contingent immunization, a stop loss strategy that allows portfolio managers to take advantage of their ability to forecast interest rate movements as long as their forecasts are successful, but switches to a pure immunization strategy should the stop loss limit be encountered. This study uses actual daily transactions in the Spanish Treasury market covering the period 1993–2003 and uses performance measures that accounts for skewness and kurtosis as well as mean variance. The main result of this paper is that contingent immunization provides excellent performance despite its simplicity.     

Property Rights and Urban Development: Initial Title Quality Matters Even When it No Longer Matters

Formal title to property allows owners to borrow for investing in improvements. Title legalization laws, however, appear to yield only modest increases in housing quality in developing countries. We offer a simple model in which squatters initially balance initial investment in low quality structures to reduce the risk of eviction against the future effect of increasing the marginal cost of improving quality. The effort to secure initial possession thereby creates a legacy effect, reducing subsequent investments in housing quality. Empirical tests using Bolivian data yield results consistent with the legacy theory: initial title risk suppresses long run housing quality.     

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.     

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.     

Proposing new variables for the identification of strategic groups in franchising

The identification of strategic groups in the Spanish franchising area is the main aim of this study. The authors have added some new strategic variables (not used before) to the study and have classified franchisors between sectors and distribution strategy. The results reveal the existence of four perfectly differentiated strategic groups (types of franchisors). One of the major implications of this study is that the variables that build a strategic group vary depending on the respective sector the network operates in and its distribution strategy. This fact indicates that including sector and distribution strategy is absolutely necessary to achieve good classifications of franchisor types.     

Stochastic comparisons of distorted distributions,coherent systems and mixtures with ordered components

A distribution function F is a generalized distorted distribution of the distribution functions \(F_1,\ldots ,F_n\) if \(F=Q(F_1,\ldots ,F_n)\) for an increasing continuous distortion function Q such that \(Q(0,\ldots ,0)=0\) and \(Q(1,\ldots ,1)=1\). In this paper, necessary and sufficient conditions for the stochastic (ST) and the hazard rate (HR) orderings of generalized distorted distributions are provided when the distributions \(F_1,\ldots ,F_n\) are ordered. These results are used to obtain distribution-free ordering properties for coherent systems with heterogeneous components. In particular, we determine all the ST and HR orderings for coherent systems with 1–3 independent components. We also compare systems with dependent components. The results on distorted distributions are also used to get comparisons of finite mixtures.     

Efficiency in a search and matching model with endogenous participation

We show that in a search/matching model with endogenous participation in which workers are heterogeneous with respect to market productivity, satisfying the Hosios rule leads to excessive vacancy creation.     

Identifying barriers to the application of standardized performance indicators in local government

Abstract

Local governments in many countries are implementing administrative reforms within the framework of New Public Management (NPM) in order to improve the quality and productivity of public services. The use of performance indicators and benchmarking facilitates evaluation of efficiency regarding the provision of such services and favours the acquisition of better practices. The problems that may arise in the introduction of performance indicators in local government mainly concern the consensual design and standardization of indicators for various entities, the method to be used for calculations and the selection of analytical criteria to be applied to the values obtained. In this article, we identify obstacles that may be encountered in achieving a standardized definition of performance indicators within local government and, on the basis of learning from the practical experience of several large city councils in Spain, formulate strategies to resolve these problems, taking note of the viability and real efficacy of the solutions adopted.     

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.     

Disclosure Strategies and Cost of Capital

Theoretically, companies disclosing more voluntary information will benefit from a lower cost of capital, although empirical research provides inconclusive results. Our study aims to analyze the influence of the disclosure of forward‐looking information on the cost of capital, because this information is extremely useful for investors. Results show that only specific information on actions, programs, decisions, and/or quantitative financial information helps toward the reduction of cost of capital. This evidence has direct economic implications, because it enables regulators and managers to focus on those disclosure strategies that are effective in the reduction of cost of capital.
