Risk and time preferences: linking experimental and household survey data from Vietnam

Abstract: We conducted experiments in Vietnamese villages to determine the predictors of risk and time preferences. In villages with higher mean income, people are less loss-averse and more patient. Household income is correlated with patience but not with risk. We expand measurements of risk and time preferences beyond expected utility and exponential discounting, replacing those models with prospect theory and a three-parameter hyperbolic discounting model. Comparable risk parameter estimates have been found for Chinese farmers, using our method.

Google Scholar, Scopus and the Web of Science: a longitudinal and cross-disciplinary comparison

Abstract: This article aims to provide a systematic and comprehensive comparison of the coverage of the three major bibliometric databases: Google Scholar, Scopus and the Web of Science. Based on a sample of 146 senior academics in five broad disciplinary areas, we therefore provide both a longitudinal and a cross-disciplinary comparison of the three databases. Our longitudinal comparison of eight data points between 2013 and 2015 shows a consistent and reasonably stable quarterly growth for both publications and citations across the three databases. This suggests that all three databases provide sufficient stability of coverage to be used for more detailed cross-disciplinary comparisons. Our cross-disciplinary comparison of the three databases includes four key research metrics (publications, citations, h-index, and hI, annual, an annualised individual h-index) and five major disciplines (Humanities, Social Sciences, Engineering, Sciences and Life Sciences). We show that both the data source and the specific metrics used change the conclusions that can be drawn from cross-disciplinary comparisons.

Increasing flood risk and wetland losses due to global sea-level rise: regional and global analyses

Abstract: To develop improved estimates of (1) #ooding due to storm surges, and (2) wetland losses due to accelerated sea-level rise, the work of Hoozemans et al. (1993) is extended to a dynamic analysis. It considers the e!ects of several simultaneously changing factors, including: (1) global sea-level rise and subsidence; (2) increasing coastal population; and (3) improving standards of #ood defence (using GNP/capita as an ‘ability-to-paya parameter). The global sea-level rise scenarios are derived from two General Circulation Model (GCM) experiments of the Hadley Centre: (1) the HadCM2 greenhouse gas only ensemble experiment and (2) the more recent HadCM3 greenhouse gas only experiment. In all cases there is a global rise in sea level of about 38 cm from 1990 to the 2080s. No other climate change is considered. Relative to an evolving reference scenario without sea-level rise, this analysis suggests that the number of people #ooded by storm surge in a typical year will be more than "ve times higher due to sea-level rise by the 2080s. Many of these people will experience annual or more frequent #ooding, suggesting that the increase in #ood frequency will be more than nuisance level and some response (increased protection, migration, etc.) will be required. In absolute terms, the areas most vulnerable to #ooding are the southern Mediterranean, Africa, and most particularly, South and South-east Asia where there is a concentration of low-lying populated deltas. However, the Caribbean, the Indian Ocean islands and the Paci"c Ocean small islands may experience the largest relative increase in #ood risk. By the 2080s, sea-level rise could cause the loss of up to 22% of the world’s coastal wetlands. When combined with other losses due to direct human action, up to 70% of the world’s coastal wetlands could be lost by the 2080s, although there is considerable uncertainty. Therefore, sea-level rise would reinforce other adverse trends of wetland loss. The largest losses due to sea-level rise will be around the Mediterranean and Baltic and to a lesser extent on the Atlantic coast of Central and North America and the smaller islands of the Caribbean. Collectively, these results show that a relatively small global rise in sea level could have signi"cant adverse impacts if there is no adaptive response. Given the ‘commitment to sea-level risea irrespective of any realistic future emissions policy, there is a need to start strategic planning of appropriate responses now. Given that coastal #ooding and wetland loss are already important problems, such planning could have immediate bene"ts. ( 1999 Elsevier Science Ltd. All rights reserved.

The Relationship Between the Comprehensiveness of Corporate Annual Reports and Firm Characteristics in Spain

Abstract: Not much information exists in the international accounting literature on Spanish accounting. Spain is selected as a subject of study because it is different from those countries that are subjects of the research concerned with investigating the multivariate impact of firm characteristics on disclosure in annual reports and accounts. The conceptual model underlying our empirical tests is based on economic and political incentives for providing greater detail in corporate annual reports and accounts. The paper provides evidence that the amount of detail in Spanish corporate annual reports and accounts is increasing in firm size and stock exchange listing, and decreasing in liquidity.
