This article investigates the effects of real exchange rate uncertainty on manufactures exports from 28 emerging economies, representing 82% of all developing country manufactures exports, and explores the sources of heterogeneity in the uncertainty effects by controlling for the direction of trade (south‐north or south‐south), and the level of financial development of the exporting country. The empirical results show that for more than half of the countries, the uncertainty effect is unidirectional, either south‐south or south‐north, and the median impact is negative. In addition, while we find that financial development augments trade, exchange rate shocks can negate this effect. Last but not least, trade among developing economies improves export growth under exchange rate shocks.  相似文献

In this paper the authors introduce a novel approach to stochastic image processing, denoted as Differential Markov Random Field (DMRF), which has been applied to gravity anomaly separation problems. The advantages of the method are that it introduces only little distortion into the shape of the original image and that it is not affected significantly by factors such as the overlap power spectra of regional and residual fields. Testing of the proposed meth using synthetic examples gave excellent results.  相似文献

Sustainability practices are critical for family firms, as they relate directly to the continuity of the business and relationships with important stakeholders, such as members of the local community. Nevertheless, not all family firms wish to adopt sustainability practices. To examine this, we draw upon the socioemotional wealth perspective in order to develop a theoretical model of the direct negative effects of family ownership on the adoption of sustainability practices. We also suggest moderating effects of long-term orientation (LTO) on this link. Our model is tested on a sample of 195 family firms in the tourism and hospitality sector. The results support our hypothesis that family ownership negatively influences the adoption of sustainability practices. Additionally, LTO moderates the relationship between family ownership and the adoption of sustainability practices, such that family owners with a high LTO are more likely to adopt this particular practice compared to those with a low LTO.  相似文献

This study uses GARCH-EVT-copula and ARMA-GARCH-EVT-copula models to perform out-of-sample forecasts and simulate one-day-ahead returns for ten stock indexes. We construct optimal portfolios based on the global minimum variance (GMV), minimum conditional value-at-risk (Min-CVaR) and certainty equivalence tangency (CET) criteria, and model the dependence structure between stock market returns by employing elliptical (Student-t and Gaussian) and Archimedean (Clayton, Frank and Gumbel) copulas. We analyze the performances of 288 risk modeling portfolio strategies using out-of-sample back-testing. Our main finding is that the CET portfolio, based on ARMA-GARCH-EVT-copula forecasts, outperforms the benchmark portfolio based on historical returns. The regression analyses show that GARCH-EVT forecasting models, which use Gaussian or Student-t copulas, are best at reducing the portfolio risk.  相似文献

The concept of reflective thinking needs to be instantiated for more effective educational implementations and practice in the process of thinking and learning. This article therefore expounds on the elicitation and classification of the Reflective Acts derived primarily from various studies conducted on reflective practice, student reflections and metacognition. In order to elicit and classify the Reflective Acts, the study employed three sequential phases of analyses: qualitative meta-analysis, purport analysis and Intention Clustering Method. As a result, 17 types of reflective acts were identified and classified into four main categories: Interpretive, Associative, Transformative and Affective. It is concluded in the article that through the presence and awareness of Reflective Acts, the concept of reflective thinking will be better comprehended, perceived and retained, engendering the process of reflective thinking into a straightforward practice to guide individuals to perform structured, efficacious and successful reflective acts in order to improve the quality of their reflective thinking and learning.  相似文献

The participation of the Ottoman Empire in the First World War caused economic disruptions, huge budget deficits, surmounted inflation rates and excessive depreciation of Lira, the Ottoman currency. Based on the value of Lira against the currencies of Switzerland, Netherlands, Sweden that were not in the war, we focus on the effects of news about the war on the foreign exchange rates at the ?stanbul bourse from 1918 to 1919. Our results signify some dates, which match the announcements of the armistices and peace meetings, heralding continuous depreciation of Lira. Thus, the findings support the presence of an expectation on the dissolution of the Ottoman Empire with the peace, marked by the escalation of the loss in trust for the Lira and the power of the state in foreign exchange interventions.  相似文献

This paper presents a comprehensive set of tests of the implications of the Arbitrage Pricing Theory. We find, unlike previously reported results, a very limited relationship between the expected returns and the covariance (factor loadings) measures of risk. Furthermore, unique variance measures of risk, while generally making only small contributions to the explanation of asset returns, turn out to be significant about as frequently as the coveriance measures of risk — which is inconsistent with the Arbitrage Pricing Theory model. The intercept tests are more mixed but provide only limited support to the model.  相似文献

We use a representative survey of the Turkish household sector and investigate factors impinging on saving-borrowing behavior. We run four probit regressions to elucidate (i) the saving decision, (ii) asset choice or portfolio composition for those who save, (iii) the bank loan decision and lastly (iv) the formal versus informal borrowing decision. We find income, education, marital status and region within country strongly correlate with those decisions. We offer some insights regarding the influence of variables like rural to urban migrant status and religious belief on saving and borrowing decisions. We discuss the long-term implications of our findings on the Turkish household savings performance.  相似文献

We analyze the roles of bank ownership, management, and compensation structures in bank failures during the recent financial crisis. Our results suggest that failures are strongly influenced by ownership structure: high shareholdings of lower‐level management and non‐chief executive officer (non‐CEO) higher‐level management increase failure risk significantly. In contrast, shareholdings of banks’ CEOs do not have a direct impact on bank failure. These findings suggest that high stakes in the bank induce non‐CEO managers to take high risks due to moral hazard incentives, which may result in bank failure. We identify tail risk in noninterest income as a primary risk‐taking channel of lower‐level managers.  相似文献

Urban plans and projects that aim to initiate the redevelopment and gentrification of urban areas create social and ecological pressures on urban environments and thereby stimulate urban movements. These movements have a lifespan, which evolves in interaction with planning authorities under local or central governments and may be marked by institutionalization and co‐optation, as well as fragmentation among the people involved in them. Fragmentations are usually based on conflicting individual and collective interests, but may also be the result of different political perspectives in groups. This article is based on a case study conducted in two adjacent gecekondu neighbourhoods of Istanbul, Gülsuyu and Gülensu, where urban politics have played an important role in efforts to resist plans for urban transformation. It shows that fragmentations are very likely to occur in urban movements during planning processes in a neoliberal era, owing to the different perspectives in the movement on what the just city is.  相似文献
