This paper examines the impact of refinancing on mortgage defaults based on an empirical investigation of the Home Affordable Refinance Program (HARP). We study a unique dataset from Freddie Mac which includes loans funded right before and after the HARP eligibility cutoff date, an exogenous event. Using a Fuzzy Regression Discontinuity Design method, we show that receiving a HARP refinance decreases the expected monthly default rate by about 48–62 percent using different bandwidth specifications. 相似文献

The recent plunge in the price of oil affected many countries, especially major oil producers and exporters, such as the Gulf Cooperation Council (GCC), which accounts for half of the global oil reserves. This paper examines the impact of oil price changes on GCC stock markets, including Bahrain, Kuwait, Oman, Qatar, Kingdom of Saudi Arabia, and United Arab Emirates over a 10-year period, 2005–2015. We examine the direction of influence and influence absorption through Granger causality and impulse response function. The results are important for portfolio management at the international level, and provide insights for government and regulatory authorities in times of oil price change. Additionally, the evidence suggests the need for more economic diversification at the country level in the GCC region to mitigate high volatility in the event of oil shocks. 相似文献

Cognitive style has been described as consistent individual differences in the organising and processing of information. It is has been argued that it is an important factor in managerial learning and cognition. A number of authors have suggested that groups from different national cultures are likely to exhibit style differences and that this has important implications for management training and development. In the present study, which employed closely matched samples of business and management undergraduates from Egypt, Greece and the UK, there were no statistically significant differences in style. However, in post‐graduate samples from Egypt, Hong Kong and the UK that were less closely matched, statistically significant differences were observed. Comparison of these data with those from other studies suggests that amongst under‐graduates from a variety of national cultures there do not appear to be significant differences in style. Among post‐graduates and managers the picture that emerges was more equivocal and the extent to which any observed differences are artefacts of sampling and method remains unclear. The implications of the findings for style theory and management education, training and development are discussed. 相似文献

Return and volatility transmission between world oil prices and stock markets of the GCC countries 总被引:1,自引:0,他引:1

This paper investigates the return links and volatility transmission between oil and stock markets in the Gulf Cooperation Council (GCC) countries over the period 2005-2010. We employ a recent generalized VAR-GARCH approach which allows for transmissions in return and volatility. In addition, we analyze the optimal weights and hedge ratios for oil-stock portfolio holdings. On the whole, our results point to the existence of substantial return and volatility spillovers between world oil prices and GCC stock markets, and appear to be crucial for international portfolio management in the presence of oil price risk. 相似文献

ABSTRACTThe goal of this paper is to investigate forecast heterogeneity and time variability in the formation of expectations using disaggregated monthly survey data on macroeconomic indicators provided by Bloomberg from June 1998 to August 2017. We show that our panel of forecasters are not rational and are moderately heterogeneous and thus confirm that previously well-established results on asset prices hold for macroeconomic indicators. We propose a flexible hybrid forecast model defined at any time as a combination of the extrapolative, regressive, adaptive and interactive heuristics. Controlling for endogenous structural breaks, we find that experts adjust their forecast behaviour at any time with some inertia in extrapolative and adaptive profiles. Changes in the formation of expectations are triggered mostly by financial shocks, and uncertainty is dealt with by using complex processes in which the fundamentalist component overweighs chartist activity. Forecasters whose models combine different relevant rules and display high temporal flexibility provide the most accurate forecasts. Authorities can then stabilize the domestic markets by encouraging fundamentalists’ forecasts through increased transparency policy. 相似文献

Recent studies have shown increasing interest on the relationship between research output and economic growth. The study of such a relationship is not only of theoretical interest, but it can also influence specific policies to improve the quality, and probably the quantity of research output. This article has studied this relationship in G7 countries using the asymmetric panel causality test of Hatemi-J (2011). Our results show that only the UK shows a causal relationship from the output of research to real GDP. However, when the signs of variations are taken into account, there is an asymmetric causality running from negative research output shocks to negative real GDP shocks. 相似文献

This article investigates the latest developments in longevity-risk modelling, and explores the key risk management challenges for both the financial and insurance industries. The article discusses key definitions that are crucial for the enhancement of the way longevity risk is understood, providing a global view of the practical issues for longevity-linked insurance and pension products that have evolved concurrently with the steady increase in life expectancy since s. In addition, the article frames the recent and forthcoming developments that are expected to action industry-wide changes as more effective regulation, designed to better assess and efficiently manage inherited risks, is adopted. Simultaneously, the evolution of longevity is intensifying the need for capital markets to be used to manage and transfer the risk through what are known as Insurance-Linked Securities (ILS). Thus, the article will examine the emerging scenarios, and will finally highlight some important potential developments for longevity-risk management from a financial perspective with reference to the most relevant modelling and pricing practices in the banking industry. 相似文献
