Strategic sharing of a costly network
2012
We study minimum cost spanning tree problems for a set of users connected to a source. Prim’s algorithm provides a way of finding the minimum cost tree mm. This has led to several definitions in the literature, regarding how to distribute the cost. These rules propose different cost allocations, which can be understood as compensations and/or payments between players, with respect to the status quo point: each user pays for the connection she uses to be linked to the source. In this paper we analyze the rationale behind a distribution of the minimum cost by defining an a priori transfer structure. Our first result states the existence of a transfer structure such that no user is willing to …
On the Consistent Use of VaR in Portfolio Performance Evaluation: A Cautionary Note
2010
The portfolio performance measures based on the Value at Risk (VaR) concept have gained widespread popularity and are often used in empirical studies. In the majority of empirical studies, however, a VaR-based performance measure is inconsistently used. In this article, Zakamouline emphasizes how to consistently use VaR in portfolio performance evaluation. He also elaborates on a simple framework that allows the derivation of a general formula for a portfolio performance measure that is not limited to the use of VaR-based reward and risk measures, but is valid for all reward and risk measures that satisfy a few plausible properties.
Gender, Social Value Orientation, and Tax Compliance
2020
AbstractThis article brings an important empirical contribution to the academic literature by examining whether gender differences in tax compliance are due to higher prosociality among women. We conducted a large cross-national tax compliance experiment carried out in different countries—Italy, UK, USA, Sweden, and Romania. We uncover that women declare a significantly higher percentage of their income than men in all five countries. While some scholars have argued that differences in honesty between men and women are mediated by prosociality, we find that women are not more prosocial than men in all countries and we do not find a mediating effect of prosocial behaviour on tax compliance. …
Teaching in times of COVID-19: determinants of teachers' educational technology use
2021
We conduct a large and nationwide survey among German teachers to investigate the determinants of teachers' adaption to an increased use of educational technology during the COVID-19 school closure...
Arbitrage opportunities and event impacts on Spanish rights issues
2022
In equity offerings in which pre-emptive subscription rights are issued, there are two ways of acquiring the company's shares: either by buying them directly on the market, or by subscribing to the new shares using the subscription rights. This could lead to the existence of arbitrage opportunities. In addition, the announcement of these processes incorporates very relevant information to the market, which could generate abnormal returns for the shares. This paper analyses both hypotheses simultaneously on the same sample and concludes that there are indeed arbitrage opportunities and also abnormal returns can be detected. Furthermore, it is also concluded that these effects are especially …
Geographic diversification and credit risk in microfinance
2019
Abstract This paper examines the relation between geographic diversification and credit risk in microfinance. The empirical findings from the banking industry are mixed and inconclusive. This study extends the discussion into a new international setting: the global microfinance industry with lenders having both social and financial objectives. Using a large global sample of microfinance institutions (MFIs), we find that geographic diversification comes with more credit risks. However, this finding is more pronounced among non-shareholder MFIs like NGOs and cooperatives, compared to shareholder-owned MFIs. Moreover, the results show that MFIs can mitigate the effect of geographic diversifica…
Does competition enhance the double-bottom-line performance of microfinance institutions?
2020
Abstract This paper investigates how competition affects the double-bottom-line performance of microfinance institutions (MFIs). While classical economic theory highlights that competition enhances efficiency and benefits both customers and firms, we argue that this is unlikely to apply to institutions operating in socially oriented industries, such as microfinance. Using a cross-country dataset of 4576 MFI-year observations (1139 unique MFIs) operating in 59 countries over a 10-year period (2005-2014), we find that competition has an adverse effect on MFIs’ economic sustainability and that competition undermines their breadth of outreach but enhances their depth of outreach. These results …
Microfinance Mission Drift?
2010
Claims have been made that microfinance institutions (MFIs) experience mission drift as they increasingly cater to customers who are better off than their original customers. We investigate mission drift using average loan size as a main proxy and the MFI?s lending methodology, main market, and gender bias as further mission drift measures. We employ a large data set of rated, multi-country MFIs spanning 11 years, and perform panel data estimations with instruments. We find that the average loan size has not increased in the industry as a whole, nor is there a tendency towards more individual loans or a higher proportion of lending to urban costumers. Regressions show that an increase in av…
The effects of religion on development efforts : evidence from the microfinance industry and a research agenda
2012
Author's version of an article in the journal: World Development. Also avaliable from the publisher at: http://dx.doi.org/10.1016/j.worlddev.2012.05.030 This study responds to the need for more empirical knowledge pertaining to the effect of religion on development efforts. We use data from the microfinance industry to study performance differences between Christian and secular Microfinance Institutions (MFIs). We find that Christian MFIs have significantly lower funding costs and consistently underperform in terms of financial profit indicators. Contrary to our hypotheses Christian MFIs are as efficient in assuring loan repayment and their average loan sizes are on par with those of their …
BOARD GOVERNANCE: DOES OWNERSHIP MATTER?
2019
Good governance is crucial to achieving an organization's mission. Nevertheless, little is known about how the structure of governance is influenced by the nonprofit (NPO) or for‐profit ownership (FPO) structure of an organization, partly because they tend to be active in different sectors. In this paper we overcome this challenge by using data from a global sample of 392 microfinance institutions. The results show that the average NPO has a larger board, more female directors, and a higher number of board meetings than the average FPO. Moreover, where there are larger boards and more frequent board meetings, this has a positive effect on the financial performance of NPOs. It is thus confir…
