Model averaging estimation of generalized linear models with imputed covariates
2015
a b s t r a c t We address the problem of estimating generalized linear models when some covariate values are missing but imputations are available to fill-in the missing values. This situation generates a bias-precision trade- off in the estimation of the model parameters. Extending the generalized missing-indicator method proposed by Dardanoni et al. (2011) for linear regression, we handle this trade-off as a problem of model uncertainty using Bayesian averaging of classical maximum likelihood estimators (BAML). We also propose a block model averaging strategy that incorporates information on the missing-data patterns and is computationally simple. An empirical application illustrates our…
Financial institutions’ risk profile and contribution to the sustainable development goals
2021
This study analyses the impact of Spanish financial institutions’ risk profile on their contribution to the 2030 Agenda. Financial institutions play a significant role in ensuring financial inclusion and sustainable economic growth and usually incorporate environmental and social considerations into their risk management systems. The results show that financial institutions with less capital risk, with lower management efficiency and with higher market risk usually make higher contributions to the Sustainable Development Goals (SDGs), according to their sustainability reports. The novel aspect of the present study is that it identifies the risk profile of financial institutions that incorpo…
EFFECTS OF SOCIAL ISOLATION ON MENTAL HEALTH DURING COVID-19 IN THE CONTEXT OF AGEING
2021
The COVID-19 pandemic brought significant changes to the usual rhythm of life. Reduced opportunities to meet with family members and friends in a situation of heightened stress leads to increased feelings of loneliness and social isolation, as well as increases the risk of mental health problems. The aim of this paper is to evaluate the effect of social contacts on the changes in psychoemotional states in the elderly population in Latvia during the crisis caused by the COVID-19 pandemic. The analysis draws upon quantitative data collected by the Survey of Health, Ageing and Retirement in Europe within Wave 8 in Latvia (n=1207). Measurements of the frequency of social contacts were used to c…
Hotel chain performance: a gravity-DEA approach
2011
Performance in business management can be measured in terms of competitiveness and efficiency. Generally speaking, competitiveness is a comparative concept of the ability of a firm, sub-sector or country to sell and supply goods and/or services in a given market, as measured by its market share. Particularly in competitive markets, efficiency plays a key role in determining this ability but it is not, by itself, sufficient. Indeed, while competitiveness has more to do with “pursuing the correct strategy” towards the conservation and/or increase of the market share, operational efficiency is mainly a measure of how well the firm, sub-sector or country under study processes inputs to achieve …
Parallel Algorithms for Listing Well-Formed Parentheses Strings
1998
We present two cost-optimal parallel algorithms generating the set of all well-formed parentheses strings of length 2n with constant delay for each generated string. In our first algorithm we generate in lexicographic order well-formed parentheses strings represented by bitstrings, and in the second one we use the representation by weight sequences. In both cases the computational model is based on an architecture CREW PRAM, where each processor performs the same algorithm simultaneously on a different set of data. Different processors can access the shared memory at the same time to read different data in the same or different memory locations, but no two processors are allowed to write i…
Make It or Break It: The Break-Through Rule as a Break-Through for the European Takeover Directive?
2003
The break-through concept is the most recent idea to break the deadlock with respect to EU takeover legislation. As devised by the High-Level Group of Company Law Experts, chaired by the Dutch Jaap Winter, the break-through concept would do away with two of the most important types of impediments to takeovers within EU member states. The first part of the paper explores the break-through concept in some detail, particularly with respect to its premises, its two guiding principles - exclusive shareholder decisionmaking and proportionality, - and the justifications given by the Group for the proposed interventionist rules. The second part of the paper is dedicated to an analysis of the econom…
Co-determination and Merger Incentives from Transfers of Wealth: Firm Owners vs. Workers
2010
When workers can capture rents from their influence on corporate decisions, mergers can become a device to generate transfers of wealth. This paper examines the merger incentives from these transfers of wealth. It is found that worker influence increases merger profitability, in line with the owners’ incentive to use mergers to reduce the rents captured by workers. In contrast, the workers’ merger incentives are shown to be decreasing in their own degree of influence on the merger decision, in line with the view according to which workers can be used by incumbent managers as a defensive instrument in acquisitions.
Creating Value – From Corporate Governance to Total Shareholders Return. An Overview
2016
Abstract The term “value” can be interpreted in a subjective way, depending about what we refer at. Usually the firm's value is related to the financial performance: profitability, cash flow, liquidity, solvability, etc. A corporation can create and in some cases reduce value for its stakeholders. Also, a corporation can create value for the stakeholders by simply creating jobs, paying taxes and help the population to improve their financial situation. The aim of the paper is to describe the process of value creation starting with corporate governance, continuing with stakeholders’ expectations and finishing with shareholders requests.
SYSTOLIC GENERATION OF k-ARY TREES
1999
The only parallel generating algorithms for k-ary trees are those of Akl and Stojmenović in 1996 and of Vajnovszki and Phillips in 1997. In the first of them, trees are represented by an inversion table and the processor model is a linear aray multicomputer. In the second, trees are represented by bitstrings and the algorithm executes on a shared memory multiprocessor. In this paper we give a parallel generating algorithm for k-ary trees represented by generalized P–sequences for execution on a linear array multicomputer.
Looking for representative fit models for apparel sizing
2014
This paper is concerned with the generation of optimal fit models for use in apparel design. Representative fit models or prototypes are important for defining a meaningful sizing system. However, there is no agreement among apparel manufacturers and each one has their own prototypes and size charts i.e. there is a lack of standard sizes in garments from different apparel manufacturers. We propose two algorithms based on a new hierarchical partitioning around medoids clustering method originally developed for gene expression data. We are concerned with a different application; therefore, the dissimilarity between the objects has to be different and must be designed to deal with anthropometr…
