Human capital in OECD countries: Technical change,efficiency and productivity

The aim of this paper is to analyse the role of human capital in the productivity gains of the OECD countries in the period 1965-90, breaking down the productivity gains into technical change and gains in efficiency. For this purpose we use both a stochastic frontier approach and a non-parametric approach (DEA) and calculate Malmquist indices of productivity. The results obtained indicate the existence of both a level effect (a higher level of human capital raises labour productivity) and a rate effect (a higher level of human capital affects positively the rate of technical change) associated with human capital. The differences among countries in endowments of human capital have worked against labour productivity convergence, since the richer countries, thanks to their greater endowment of human capital, have experienced higher rates of technical change.     

Analysis of compensatory financing schemes for export earnings fluctuations in developing countries

Several recent initiatives in the area of compensatory financing have pushed this issue into the forefront of discussion between developed and developing countries. This study performs simulations of various types of compensatory financing schemes assuming they had been in operation during the 1960s and early 1970s and draws some conclusions with respect to the relative costs and benefits of such schemes and with respect to their coutry and regional distribution. The results show that a compensatory financing scheme broadly defined is a flexible financial instrument which can be useful in helping developing countries with export instability problems.     

Political determinants of fiscal transparency: a panel data empirical investigation

The investigation of the determinants of fiscal transparency has been mostly performed on cross-sectional data, and it has produced mixed results. This paper improves the existing literature by performing a static and dynamic panel analysis of the effect of a set of political variables on the level of fiscal transparency in 36 democratic countries. By using a recent measure of fiscal transparency based on IMF Governance Finance Statistics and available from 2003 to 2013, we find strong links between political environments and the dynamics of fiscal disclosure. Our results show that government control over the legislature exerts some negative effect on fiscal transparency, while the effect of government ideology is shown to be at least fragile. Furthermore we find that legislature fragmentation exerts a negative effect on fiscal transparency, which suggests that competition within the parliaments does not increase fiscal transparency, but instead it induces governments to react by reducing accessibility to information.     

E-Index for measuring concentration

The goal of measuring the existing concentration of an economic magnitude among the elements in which it is distributed has been over the past years one of the major worries in the economic statistics arena. Among all the concentration indexes, the Gini index has been applied to a greater extent. This study considers that the traditional Gini index definition, according to a wide array of introductory statistics textbooks, is only applicable in the case of unitary frequency distributions. When dealing with nonunitary frequency distributions, it is possible to convert them into unitary ones, allowing for the application of the Gini index. Nevertheless, it can be appreciated how laborious such a task will be in those cases where the number of elements of the distribution is of considerable magnitude. The aim of this paper is to avoid this handicap by presenting an alternative index, the E-index.     

Reputation When Threats and Transfers Are Available

We present a model where a long run player is allowed to use both money transfers and threats to influence the decisions of a sequence of short run players. We show that threats might be used credibly (even in arbitrarily short repeated games) by a long-lived player who gains by developing a reputation of carrying out punishments. Particular cases of the model are a long-lived pressure group offering rewards and punishments to a series of targets (public or corporate officials) in exchange for policy favors, or that of a long-lived extorter who demands money in order not to punish. We use the model to analyze the "convicted nonpayor" debate around judicial corruption. The model highlights formal similarities between lobbying and extortion.     

The decision-influencing use of performance measurement systems in relationships between headquarters and subsidiaries

Although theoretical frameworks assume that performance measurement systems (PMS) can be employed for different uses, there is a lack of prior empirical research examining the use of PMS. In addition, recent International Business studies reveal many unresolved issues about the use of PMS to manage relationships between headquarters and subsidiaries. After summarizing the evolution of the use of PMS over three International Business eras, we focus on the decision-influencing use of PMS, operationalized as the influence of the PMS implemented by headquarters on subsidiaries’ decisions. Based on International Business literature and Management Accounting research, we hypothesize that the subsidiary participation in PMS design, measurement diversity in PMS structure, the linking of PMS to reward, as well as headquarters’ national culture, subsidiary size, and global pressure affect the influence of PMS on subsidiaries’ decisions. We collected data through questionnaires emailed to 100 subsidiaries. Findings show that PMS have a greater influence on decisions in cases of higher subsidiary's participation in PMS design, headquarters’ cultural tolerance for uncertainty, subsidiary size, and global pressure. Contrary to what is contended by advocates of multidimensional approaches to PMS, measurement diversity and the linking of PMS to reward mechanisms do not have a significant impact on the decision-influencing use. We discuss the empirical evidence providing qualitative arguments derived from a focus group, which reveals the existence of a PMS decoupling and helped us to describe four situations with different levels of decision-influencing use of PMS and different economic performance results. The presented quantitative and qualitative empirical evidence offers several insights for research on PMS within multinational companies.     

Modeling current and emerging threats in the airport domain through adversarial risk analysis

Airports are critical infrastructures entailing intense human, commercial and economic activity. As such, they are preferred targets for criminal and terrorist groups, who are attracted by the promisingly high revenues they might get from an attack. Every year, airport authorities worldwide have to face, with limited resources, attacks arising from different adversaries. There are several sensible areas within an airport organization that are especially vulnerable to the terrorist threat, including, among others: (1) those related to human lives (of passengers or staff); (2) airport infrastructure (airport perimeter, main terminal, Air Traffic Control Tower, runways, hangars, etc.); (3) aircrafts and other ground vehicles; and (4) IT systems and services. Besides the more traditional ones, we are particularly concerned with attacks launched against the last type of targets, an emerging and increasingly worrisome threat. Specifically, we analyze the impact of cyber-attacks launched by organized groups whose main goal is to take hold of airport operations. In some cases, in order to have more chances to achieve their purpose (and take advantage of its eventual success), cyber attackers may be backed up by a terrorist group who will try to interfere with the Air Traffic Management network. In this paper, we aim at supporting airport authorities in their fight against both threats, by devising a security allocation plan. We provide an adversarial risk analysis model to address the problem, and apply it to obtain the optimal portfolio of preventive measures in an illustrative case study. The model is open to extensions, as e.g. larger and more complex technical infrastructures, new threats, or additional recovery measures deployed by different defensive agents.     

Multiperiod analysis of a levered portfolio

The notion of Internal Financial Law for an investment is introduced. Through this generalization of the IRR a general notion of outstanding capital is obtained. After the introduction of a generalized version of NPV a decomposition of this parameter is offered which is strictly connected to the notion of ROE.Some applications to yield averaging for portfolios is provided.     

Extreme Value Analysis of Mortality at the Oldest Ages: A Case Study Based on Individual Ages at Death

In this article, the force of mortality at the oldest ages is studied using the statistical tools from extreme value theory. A unique data basis recording all individual ages at death above 95 for extinct cohorts born in Belgium between 1886 and 1904 is used to illustrate the relevance of the proposed approach. No leveling off in the force of mortality at the oldest ages is found, and the analysis supports the existence of an upper limit to human lifetime for these cohorts. Therefore, assuming that the force of mortality becomes ultimately constant, that is, that the remaining lifetime tends to the Negative Exponential distribution as the attained age grows is a conservative strategy for managing life annuities.
