We explore the dependency between currency crises and the stock market in emerging economies. Our focus is two-fold. First, the risk of a currency crisis rises as the foreign stake in the domestic stock market increases. Successful economies with high capital flows into their booming stock markets especially are prone to stock market-induced currency crises. Second, we apply the dividend growth model to show that stock markets crash in the run-up to a currency crisis. This new type of twin crisis is empirically tested by employing a logit framework using quarterly data for 33 emerging economies for 1994Q1–2007Q4. 相似文献

Zusammenfassung Wenn Unternehmen bei beschr?nkten Kapazit?ten mehrere Investitionsprojekte durchführen
k?nnen, stellt sich die Frage nach der optimalen Reihenfolge dieser Projekte. Ein Entscheidungskriterium
in Analogie zur Annuit?t kann zur Bestimmung der optimalen Abfolge herangezogen werden. Bestehen für
die Projekte zeitliche Restriktionen in Form von sp?test zul?ssigen Endterminen, so kann die optimale
Abfolge nur noch mit einem nicht-linearen Modell ermittelt werden. Dieses Modell kann in ein gemischt-ganzzahliges
lineares Programm transformiert und mit g?ngigen Softwarepaketen gel?st werden.

Recent changes in energy economic frameworks conditions lead to new requirements for energy systems models. Particularly in Germany, structural and locational changes in the power plant sector can be observed. Above all, this is due to the liberalisation process entailing the legal unbundling of system operators and generation companies as well as to the ambitious aims for the extension of wind energy. Consequently, modelling energy systems as single node systems, in which network constraints are neglected, can lead to suboptimal results. Most energy systems models offer the possibility to limit interregional energy exchange capacities. However, these so-called transhipment models normally neglect the actual load flows. Yet, there are several possibilities to adequately consider the characteristics of power transmission. In this paper, the most popular approaches, which are used in particular technical applications, such as the AC- (Alternating Current), the DC- (Direct Current) and the PTDF- (Power Transfer Distribution Factors) approach are introduced and discussed with respect to their application in energy systems models. In addition, first experiences with their implementations are presented. 相似文献

Interval bidding allows people to report a range of values for a non-market good. Herein, we allow people to choose their distribution over this range endogenously. We consider a multiplicative error model explaining the willingness to pay (WTP) which is estimated using a feasible generalized least squares estimator. We apply our framework to a representative sample of the French population who were asked about the valuation of a bear conservation programme. We find that most participants prefer stating their WTP as a range rather than a point, but the shape of the distribution greatly varies across people. Our results support the use of the interval bidding with endogenous distribution approach in valuation studies. 相似文献

Recently, concerns have been rising that the energy transition may impair the security of power supply in Germany by increasing the risk of shortages and black-outs in the long run. While power generation from volatile wind and solar energy has grown rapidly, incentives to invest in conventional back-up capacity have diminished. To respond to these concerns, the German government has adopted an energy policy reform package to strengthen the regulatory framework for the power market. But is this package appropriate to sustainably safeguard the German power supply? 相似文献

Relational Goods and Associational Participation 总被引:3,自引:0,他引:3

Abstract *** : In this paper, we focus on the role of interpersonal contact and the possibility of a relational motive to explain participation and volunteering in associations. Drawing on the relational goods theory, we show that associational activities are favorable to production and consumption of such goods. So, associational participants are expected to have more personal interactions. This theoretical hypothesis is tested using a cross‐sectional data set conducted in France in 1999. Our econometric analysis, which controls for endogeneity of associational participation using a simultaneous equations model, emphasizes a significantly positive relationship between this participation and preferences for relational goods . 相似文献
