“Into and Out of” the Qinghai‐Tibet Plateau and the Himalayas: Centers of origin and diversification across five clades of Eurasian montane and alpin…

2020

Abstract Encompassing some of the major hotspots of biodiversity on Earth, large mountain systems have long held the attention of evolutionary biologists. The region of the Qinghai‐Tibet Plateau (QTP) is considered a biogeographic source for multiple colonization events into adjacent areas including the northern Palearctic. The faunal exchange between the QTP and adjacent regions could thus represent a one‐way street (“out of” the QTP). However, immigration into the QTP region has so far received only little attention, despite its potential to shape faunal and floral communities of the QTP. In this study, we investigated centers of origin and dispersal routes between the QTP, its forested m…

Unveiling the Antecedents of International Diversification: An Agency Theory Approach

2014

While various studies have developed hypotheses about the antecedents of international diversification drawing mainly on the resource-based view, the behavioral theory of the firm, and the transaction costs literature, we advance our understanding by investigating the explanatory power of agency costs of free cash flow arguments. Using a sample panel of 167 Italian firms longitudinally evaluated during the 1980-2010 period, this study tests whether the firm’s choice to spread operations in multiple foreign countries is conditioned by excess of free cash flow and debt, especially in firm-contexts where agency problems are exacerbated by managers or large shareholders’ opportunism. We find th…

Portfolio diversification in the sovereign credit swap markets

2018

We develop models for portfolio diversification in the sovereign credit default swaps (CDS) markets and show that, despite literature findings that sovereign CDS spreads are affected by global factors, there is sufficient idiosyncratic risk to be diversified. However, we identify regime switching in the times series of CDS spreads and spread returns, and the optimal diversified strategies can be regime dependent. The developed models trade off the CVaR risk measure against expected return, consistently with the statistical properties of spreads. We consider three investment strategies suited for different CDS market participants: for investors with long positions, speculators that hold unco…

Multidimensional financial development, exporter behavior and export diversification

2020

Financial development shapes export sector performance because exporters need external finance and face credit constraints. Previous empirical research has relied largely on single-country studies. The Exporter Dynamics Database (EDD), which features firm-level exports from over 60 countries, reveals differences in the microstructure of the export sector across countries. In this paper, we first provide new evidence that these differences are related to cross-country variation in financial development and structure. Second, we combine the EDD and multidimensional data on financial development with a global database on export diversification. This study is the first to examine how macrolevel…

Rural livelihood diversification: a solution for poverty in the post‐Soviet rural Baltic states?

2019

This article analyses rural livelihood diversification through a longitudinal follow‐up survey, that targets former collective farm workers in Estonia, Latvia and Lithuania. It argues, that between 1995 and 2010 the former collective farm workers employed three distinct livelihood diversification strategies in order to create their living. A wage‐based livelihood diversification strategy, which does not include any agricultural practices, was more common among the better‐off households. A farm‐based livelihood diversification strategy, which does not rely on salaries, was more often employed by the poor. A mixed strategy, that combines both wage income and farm activities, was used by both …

Revamping Research on Unrelated Diversification Strategy: Perspectives, Opportunities and Challenges for Future Inquiry

2015

With the aim of achieving an advanced understanding of current research on unrelated diversification and providing fruitful groundwork to foster active interchange between disciplinary traditions, this paper detects articles from two relevant research streams; i.e., strategic management and financial economics. We first provide a brief overview of management thinking on unrelated diversification strategy. Then, we present a conceptual map that offers a comprehensive appreciation of unrelated diversification strategy antecedents (i.e., environmental and institutional, organizational value-enhancing, and managerial drivers), implementation process (i.e., managerial complexity, misallocation o…

Ethnic differences in utilization of online health information sources : A test of the social inequality hypotheses

2023

The goal of the current study was to understand ethnic differences in use of online health information sources. Social stratification and social diversification hypotheses were used as study’s theoretical framework. The data were obtained from the 2017 Israel Social Survey (N = 2166). Multinomial and logistic regression techniques were used for the multivariate analysis. The results suggest that Israeli Arab respondents were less likely than Israeli-born Jewish respondents to seek health information using the Health Funds’ call centers or websites, other websites, and to utilize any number of the online health information sources. The findings provide a strong support for the social strati…
