Determining the indicators of social capital theory to social network sites
2014
The authors theoretical research provided a framework to define and measure social capital in social network sites. This paper determining with a qualitative method the theoretical dimensions of this framework. The result of this paper is the explanation of social capital theory in social network sites under the consideration of the identified indicators. The sample for this case is students, and the research needs further confirmation by other samples and methods. But this paper gives a first interesting insight in social network sites explained with the social capital theory and provides a first guidance for further research projects.
A Problem of Optimization in a Case of Foreign Investment
2000
The aim of the paper is to solve an optimization problem in an economic system with a central bank and a set of private agents. Each agent aims to maximize her expected utility, with rational expectations and being risk averse. The agents follow a profitability-risk criterium to face the portfolio diversification problem between foreign or domestic investment. An explicit formula for the optimal amount of foreign investment as a function of the expected exchange rate and an explicit formula for the exchange rate are obtained. These formulas show the hard influence of the expected exchange rate, the variance and the risk aversion on the agents’ decisions.
Mirror, Mirror on the Wall: Machine Predictions and Self-Fulfilling Prophecies
2021
We show that disclosing machine predictions to affected parties can trigger self-fulfilling prophecies. In an investment game, we experimentally vary investors’ and recipients’ access to a machine prediction about recipients’ likelihood to pay back an investment. Recipients who privately learn about an incorrect machine prediction alter their behavior in the direction of the prediction. Furthermore, when recipients learn that an investor has disregarded a machine prediction of no-repayment, this further lowers the repayment amount. We interpret these findings as evidence that transparency regarding machine predictions can alter recipients’ beliefs about what kind of person they are and what…
Performance and international investments in microfinance institutions
2013
Preprint of the published version of an article from Strategic Change Using data from 319 microfinance institutions (MFIs) in 68 developing countries, we study the degree to which international debt investments are related to the financial and social performances of MFIs. We find that commercial investments are mainly related to financial performance and level of professionalisation of the MFIs. The targeting of women is not a priority, even though international commercial investors target MFIs that provide small loans. Subsidised investments, however, are mainly driven by the targeting of women, while financial performance and the level of professionalisation of the MFI is not a priority.
ICT Diffusion and Foreign Direct Investment
2011
This chapter investigates the impact of inward and outward FDI on ICT diffusion in the Asia-Pacific and Middle East regions for the period 1996-2008. The results indicate that while inward FDI has generally had a positive and significant impact on ICT diffusion in Asia-Pacific economies, its impact on the Middle Eastern countries has been detrimental. In contrast, the results of this study also show that outward FDI has had, in general, the inverse effect, it has been in general positive and significant for the Middle East countries but insignificant for Asia-Pacific economies.
The Determinants of Migrants’ Remittance Inflows in the MENA Region: A Macroeconomic Approach
2014
Macroeconomic studies on the determinants of remittance flows have traditionally reviewed the role that economic conditions of host and home countries of migrants play in this process. New contributions have enlarged that setting by dealing with socio-political (demographics, institutions) and individual (education) dimensions influencing migrants’ behaviour when they remit money back home. In this investigation, we test for the role of all these variables in a general framework when analysing the case of the MENA (Middle East and North of Africa) region. Results indicate that the state of the business cycle, the characteristics of households (fertility, income per capita), and those of the…
L'assistenza umanitaria delle ONG sotto inchiesta
2022
Lo scorso giugno, l’Agenzia dell’Unione europea per i diritti fondamentali (FRA) ha pubblicato il consueto aggiornamento semestrale sulle operazioni di Search and Rescue (SAR) nel Mediterraneo. Il documento evidenza le difficoltà di condurre le operazioni di salvataggio da parte delle imbarcazioni delle ONG, molte delle quali sono state (e continuano ad essere) sottoposte a procedimenti giudiziari e fermi amministrativi nelle giurisdizioni degli Stati membri dell’UE. Nel quadro del contrasto al traffico di migranti, infatti, è ormai impellente una riforma del Facilitator Package quantomeno nel senso di vietare agli Stati membri di criminalizzare l’attività di assistenza umanitaria delle ONG…
La construcción del conocimiento escolar en la sociedad de las comunicaciones. Una propuesta del proyecto Gea-Clío
2011
El estudio de las concepciones espontáneas de las personas nos muestra la influencia de los medios de comunicación en su construcción. Para poder entender el presente y explicar sus factores es preciso situar los hechos en el tiempo y en el espacio. El proyecto curricular Gea-Clío lo ha intentado a lo largo de veinte años de existencia. Sus metas y dudas, así como la comparación con otros grupos, nos muestran la importancia de los proyectos curriculares para mejorar la educación.
Identifying Portfolio-Based Risk Factors in Foreign Exchange Markets
2018
This paper shows that a link between the conditional mean and conditional volatility of any factor-mimicking portfolio in the foreign exchange (FX) market must exist if the proposed portfolio-based currency factor is priced and the pricing kernel has a linear factor structure. Thereby, this paper tests whether the carry risk factor and currency momentum are priced risk factors. Surprisingly, the carry risk factor does not meet the necessary conditions consistent with being a priced risk factor, whereas currency momentum indeed meets those criteria. The findings also indicate that the relation between the conditional mean and conditional risk is moreover economically reasonable for the curre…
Return Dispersion and Cross-Sectional Asset Pricing Anomalies
2015
Recent research finds that cross-sectional return dispersion provides a risk-based explanation for some investment anomalies, including accrual, investment, and momentum strategies. This study extends the analyses of return dispersion to a broad set of anomalies by testing whether the state of return dispersion is associated with anomalous returns. Empirical results for 12 well-known anomalies indicate a robust link between good and bad states of return dispersion and most anomalies. Also, return dispersion helps to explain a number anomalies regardless of their association with investor sentiment. We conclude that market risk related to return dispersion plays an important role in many inv…
