Around US$600 billion of investment is desperately needed to address forecasted huge shortages in water supply globally. A number of worldwide investors – so-called water funds – have started to take up this challenge. For these global water investors, knowledge about the extent of integration between the water sectors of financial markets is highly important. According to international portfolio diversification theory, the less (more) integrated markets are, the more (less) benefits there are from international diversification. In this study, we investigate the extent and manner of interdependence among the US, European and Asian water sector of the equity markets based on Vector Autoregression (VAR), Granger causality and impulse response analyses. We find that world water stock market prices are indeed significantly interdependent although this interdependence varies across time periods. Each market quickly responds to shocks from each other and completes its response within 3 days. Hence, for water investors, international diversification that is undertaken just within the water sector will not be beneficial. The result also implies that there is the risk of crossmarket contagion – that is, price volatility spill over across water sectors of different financial markets, and therefore, water authorities in one market should take cognisance of events in other markets. 相似文献

Accurately measuring Turkey's informal sector is important for policymaking. We utilize household income‐expenditure surveys to examine this sector's income underreporting. The Pissarides‐Weber approach hypothesizes that data would reflect such underreporting as “excess food consumption”. Our results suggest informal sector members spend more than their formal sector counterparts with comparable reported income levels. Using this information, we estimate the average size of the true informal sector to be about 1.25 times the official estimate. The informal sector accounts for around 83% of officially reported disposable income. Therefore, true Turkish disposable income is (25%)?(83%), roughly 21% larger than the officially estimated magnitude. 相似文献

This paper examines Official Development Assistance (ODA) in the aftermath of large natural disasters between 1970 and 2008. Using an event‐study approach, the paper finds that while the median increase in ODA is 18% compared with pre‐disaster flows, the typical surge is small in relation to the size of the affected economies. Moreover, aid surges typically cover only 3% of the total estimated economic damages caused by the disasters. The main determinants of post‐disaster aid surges are found to be the intensity of the event itself and the recipient country's characteristics such as the level of development, country size and the stock of foreign reserves. The paper does not find evidence that political considerations or strategic behavior on the part of donors determine the size of post‐disaster aid surges. 相似文献

Although organizations invest billions of dollars in training every year, many trained competencies reportedly fail to transfer to the workplace. Researchers have long examined the ‘transfer problem’, uncovering a wealth of information regarding the transfer of training. Inconsistencies remain, however, and organizations may find it difficult to pinpoint exactly which factors are most critical. Using Baldwin and Ford's model of transfer, we identify the factors relating to trainee characteristics (cognitive ability, self‐efficacy, motivation, perceived utility of training), training design (behavioral modeling, error management, realistic training environments) and the work environment (transfer climate, support, opportunity to perform, follow‐up) that have exhibited the strongest, most consistent relationships with the transfer of training. We describe our reasoning for extracting such variables from the literature and conclude by discussing potential implications for practice and future research. 相似文献
