We present an analysis of the determinants of de jure and de facto exchange rate regimes based on a panel probit model with
simultaneous equations. The model is estimated using simulation-based maximum likelihood methods. The empirical results suggest
a triangular structure of the model such that the choice of de facto regimes depends on the choice of de jure regimes but
not vice versa. This gives rise to a novel interpretation of regime discrepancies.

ABSTRACTThe benefits of biofuels depend on the feedstock, conversion pathway and local context. This paper assesses biofuels technology readiness and developments to provide foresight to biofuels development in Southern Africa. Efficient conversion pathways, coupled with biomass from waste or high-yielding energy crops, will reduce both the costs of biofuels production, and the environmental impacts. Compared to petroleum fuels, the current commercial biofuels (ethanol, biogas and biodiesel) typically offer carbon emission reductions of 30–50% but are marginally more expensive. The extent of biofuels market penetration will therefore be influenced by mandates (blending targets) and subsidies (green premium). Advanced biofuels promise greater efficiencies and carbon emission reductions at reduced cost but will require further research and development to reach commercialisation. If developed appropriately, biofuels can reduce carbon emissions and improve energy security, while enabling sustainable agriculture and improved natural resources management. 相似文献

This study advances a theory of how different aspects of emotion regulation influence individual leader emergence in the intensely emotional context of nascent venture teams. Despite the growing amount of research on the role of leadership in the entrepreneurial process, the emergence of leaders in nascent venture teams has rarely been explored. Drawing on theories and research on leadership emergence and emotion regulation, we argue that the two aspects of emotion regulation (i.e., reappraisal and suppression) exert opposite effects on the degree to which nascent venture team members come to perceive an individual as a leader. We also theorize that team emotions arising from affective events moderate the relationship between reappraisal and leader emergence in such teams. Data from 103 nascent venture teams without prior leaders show a negative relationship between individuals’ trait disposition to suppress emotions and their emergence as leaders, and a positive relationship between their trait disposition to reappraise emotions and their emergence as leaders. Moreover, we find that negative team emotions magnify the positive association between reappraisal and leader emergence, while positive team emotions mitigate it. We discuss the implications of our findings for the literature on entrepreneurial leadership, entrepreneurial emotions, and leadership in general. 相似文献

This paper uses a simple model of mean-variance capital markets equilibrium with proportional transactions costs to analyze the competition of stock markets for investors. We assume that equity trading is costly and endogenize transactions costs as variables strategically influenced by stock exchanges. Among other things, the model predicts that increasing financial market correlation leads to a decrease of transaction costs, an increase in cross-border trading activity, and to a decrease in the home bias of international equity flows. These predictions are consistent with the recent evolution of international stock markets. 相似文献

We suggest a simple framework for characterizing alternative ways that “persuasive advertising” may affect consumer preferences. We illustrate the implications of our theory—and contrast it with results from models of informative advertising—by analyzing the relationship between the degree of product differentiation and equilibrium levels of advertising. The analysis suggests that a positive relationship between equilibrium levels of advertising and (inherent) product substitutability is consistent only with advertising that “increases perceived product differences.” 相似文献

The over performance of hedge funds until the current financial market turbulences led to a large number of insurers increasing their hedge funds quota. In the following this asset class is examined and particularly analyzed with respect to its adequacy for an insurance company's asset allocation by focusing on the axiom of safety, as demanded by national law. The problem of survivorship-bias and the Markowitz requirements of normal-distribution and constant correlations among the asset classes and their impact on a strategic asset allocation are studied. 相似文献

Unemployment in South Africa has multiple causes. This article uses a district pseudo-panel to estimate the elasticity of labour demand, labour supply and unemployment with respect to wages. We assess whether hiring decisions are more sensitive to increases in wages of low-paid workers than high-paid workers, and whether wage growth prompts entry into the labour market. These channels combine to result in the positive causal effect of wage growth on unemployment. The research investigates whether these effects are dominated by districts in which unionisation rates are high and employment is concentrated in large firms. Wage growth of middle-paid to highly paid workers – as opposed to low-paid workers – reduces local labour demand and raises local unemployment. Bargaining arrangements correspond closely to the spatial wage distribution; in turn, a large part of the impact that wage growth has on labour market outcomes is determined by these wage-setting institutions. 相似文献

This paper describes algorithms for finding all Nash equilibria of a two-player game in strategic form. We present two algorithms
that extend earlier work. Our presentation is self-contained, and explains the two methods in a unified framework using faces
of best-response polyhedra. The first method lrsnash is based on the known vertex enumeration program lrs, for “lexicographic reverse search”. It enumerates the vertices of only one best-response polytope, and the vertices of the
complementary faces that correspond to these vertices (if they are not empty) in the other polytope. The second method is
a modification of the known EEE algorithm, for “enumeration of extreme equilibria”. We also describe a second, as yet not implemented, variant that is space
efficient. We discuss details of implementations of lrsnash and EEE, and report on computational experiments that compare the two algorithms, which show that both have their strengths and weaknesses. 相似文献

ABSTRACT“Sustainability” has turned into a buzzword for businesses around the globe as consumers in mature and, increasingly, in emerging markets shift their demand toward sustainably enhanced products. Surprisingly, a global picture of consumers' expectations regarding sustainable products is still missing. This study uses exploratory factor analysis to determine the perceived importance and interrelation of selected sustainability aspects in three developed (Germany, Switzerland, United States) and three emerging (Brazil, China, India) markets. Results are linked to national cultural value theory to explore which sustainability aspects and positioning strategies may be promising to expand the outreach of sustainable products in developed and emerging markets alike. Results suggest that across the sampled economies, sustainability is increasingly considered as being comprised of a health aspect. While health and quality of life aspects emerged as key issues across countries, cultural backgrounds and local market conditions resulted in nuanced expectations of sustainability, which should be kept in mind in communicating and positioning sustainable products. 相似文献
