Algorithms for the Maximum Weight Connected $$k$$-Induced Subgraph Problem
2014
Finding differentially regulated subgraphs in a biochemical network is an important problem in bioinformatics. We present a new model for finding such subgraphs which takes the polarity of the edges (activating or inhibiting) into account, leading to the problem of finding a connected subgraph induced by \(k\) vertices with maximum weight. We present several algorithms for this problem, including dynamic programming on tree decompositions and integer linear programming. We compare the strength of our integer linear program to previous formulations of the \(k\)-cardinality tree problem. Finally, we compare the performance of the algorithms and the quality of the results to a previous approac…
SHAPES secure cloud platform for healthcare solutions and services
2020
The SHAPES project is an ambitious endeavour that gathers stakeholders from across Europe to create, deploy and pilot at large-scale a EU-standardised open platform incorporating and integrating a broad range of solutions, including technological, organisational, clinical, educational and societal, to enable the ageing population of Europe to remain healthy, active and productive, as well as to maintain a high quality of life and sense of wellbeing for the longest time possible. Not only each digital solution will be ethical, legal and appropriate for users, but also the results will align with the full and ethically responsible end-to-end exploitation of the new functionalities empowered b…
Bases para el análisis económico de los sistemas de compliance penal
2019
Compliance programs and systems of criminal or administrative liability are being increasingly adopted by different countries as measures meant to reduce the social cost of white collar criminality. However, the legal application of these measures does not always ponder correctly the impacts on common good, the levels of economic activity and the adequate functioning of markets of goods and services. Eventually, this situation can lead to undesired effects, such as the inefficiency of the criminal system, the reduction of economic activity or the arising of obstacles to competition. By taking these circumstances into account, in this paper we will utilize the Economic Analysis of Law to ana…
Trade Liberalization and Heterogeneous Technology Investments
2015
We propose a trade model where heterogeneous firms decide on a productivity-enhancing technology investment. The model analyzes the impact of multilateral trade liberalization on firm- and industry-level productivity. Freer trade increases the incentives to invest in technology by raising export profits. It also dampens these incentives, however, as profits stemming from domestic sales are reduced. Only exporters benefit from the former positive effect. The shape of the distribution of efficiency draws, the level of trade costs and the technology intensity of the industry are key elements removing the ambiguities regarding the net impact of trade liberalization.
Financial wealth, socioemotional wealth, and founder exits: an empirical examination of Chinese IPOs
2021
Initial public offerings (IPOs) are typically viewed as the peak of entrepreneurial success, providing founder-CEOs a chance to profitably exit. Founder-CEOs, however, are often motivated by non-financial considerations in addition to the desire to amass wealth. According to the behavioral agency model, the founder-CEOs’ framing of gains vs. losses of their wealth creation at IPO determines their risk aversion vs. risk taking behaviors. In addition, the behavioral agency model argues that founder-CEOs with a great deal of socioemotional wealth fear losing that wealth. This fear will attenuate their aversion to losing financial wealth. To test our model, we collected a sample of 130 entrepre…
Ownership, Board Compensation and Company Performance in Sub-Saharan African Countries
2013
In countries with weak institutions, board governance becomes more important. This study uses a unique dataset from listed sub-Saharan African companies to examine the relationship between ownership composition and board compensation. It further analyses the association between board compensation and company performance. The findings indicate that board ownership and chief executive officer ownership are positively associated, whereas state ownership and concentrated ownership are negatively associated with board compensation. There is no evidence of a significant association between chairperson ownership or foreign ownership and board compensation. Finally, there is a negative but not sig…
Founding-family-controlled firms, intergenerational succession, and firm value
2022
Using a unique, hand-collected data sample and panel-data econometric techniques, we analyse the impact of founding-family control and intergenerational succession on the value of Chilean listed companies. After controlling for firm- and ownership-specific characteristics, we find an inverse U-shaped relationship between a founding family’s degree of ownership and firm value. Hence, family ownership at first increases firm value. However, when family ownership exceeds a threshold of about 38 percent of outstanding shares, the family takes advantage of its power in the firm and extracts wealth from minority shareholders. Further, if the founder of the company is the CEO or chairman of the bo…
The CEO autonomy–stewardship behavior relationship in family firms: The mediating role of psychological ownership
2014
Abstract This study investigates the relationship between a family business CEO's autonomy and stewardship behavior. Building on psychological ownership theory, we argue that psychological ownership mediates the autonomy–stewardship relationship. In contrast to prior studies, we differentiate between individual-oriented and collective-oriented psychological ownership as two distinct dimensions of individual psychological ownership. Our results reveal that CEO autonomy is an important determinant of stewardship behavior and that this relationship is only mediated by individual-oriented psychological ownership. Moreover, both individual-oriented and collective-oriented psychological ownership…
Who Uses Intermediaries in International Trade? Evidence from Firm-level Survey Data
2013
The present paper uses data from the World Bank Enterprise Survey conducted in Turkey in 2005 to shed light on the firms that use intermediaries in international trade. It lends robust empirical support to recent theories which suggest that indirect exporters are mostly small firms that are not profitable enough to cover the high fixed costs of building an own distribution network abroad. Manufacturers who develop new products are more likely to use trade intermediaries, as are firms that produce low-quality goods. In contrast, neither foreign ownership nor credit constraints are correlated with the choice of export mode. Moreover, firms that rely on trade intermediaries to sell their goods…
The Taxation of Financial Capital Under Asymmetric Information and the Tax-Competition Paradox
2003
Information sharing between governments is examined in an optimal-taxation framework. We introduce a taxonomy of alternative systems of international capital-income taxation and characterize the choice of tax rates and information exchange. The model reproduces the conclusion found in earlier literature that integration of international caopital markets may lead to the under-provision of publicly provided goods. However, in contrast to previous results in the literature, under-provision occurs due to inefficiently coordinated expectations. We show that there exists a second equilibrium with an efficient level of public-good provision as well as complete and voluntary information exchange be…
