Money pools are ancient African traditions that speak to the functionality of getting things done by a historically oppressed group of people. The analysis for this study is based on 583 interviews in five Caribbean countries: Haiti, Grenada, Jamaica, Trinidad and Tobago, and Guyana. African traditions of collectives reveal that Black people have long had money pools that focused on helping people thrive in commerce, including during the hard times of slavery and colonization. This research argues that throughout the Caribbean indigenous banking systems—with localized names such as susu, partner, meeting-turn, box-hand and sol—are long-standing ancient traditions that historically and currently are taking a bold stand against exclusionary financial systems. African-Caribbean people have an important legacy on the social economy through money pools. The ways in which persons of African descent organize in the social economy is vital to unravelling the market fundamentalist view that there is only a singular way to do business in society.  相似文献

The purpose of this research is to analyze tourism competitiveness in middle-east countries by using travel and tourism competitiveness index published in the report of the world economic forum. The used model is performed to analyze Promethee model and comparative analysis on the basis of data in 2015 and 2017. The analysis results showed that although Egypt, Iran, Kuwait, Lebanon and yamen improved their situation in comparison to 2015, they couldn’t improve their own competition power in comparison to other middle-east countries, and they were located in the group of countries with lower tourism competitiveness.  相似文献

As a threat for transportation system, traffic crashes have a wide range of social consequences for governments. Traffic crashes are increasing in developing countries and Iran as a developing country is not immune from this risk. There are several researches in the literature to predict traffic crash severity based on artificial neural networks (ANNs), support vector machines and decision trees. This paper attempts to investigate the crash injury severity of rural roads by using a hybrid clustering and classification approach to compare the performance of classification algorithms before and after applying the clustering. In this paper, a novel rule-based genetic algorithm (GA) is proposed to predict crash injury severity, which is evaluated by performance criteria in comparison with classification algorithms like ANN. The results obtained from analysis of 13,673 crashes (5600 property damage, 778 fatal crashes, 4690 slight injuries and 2605 severe injuries) on rural roads in Tehran Province of Iran during 2011–2013 revealed that the proposed GA method outperforms other classification algorithms based on classification metrics like precision (86%), recall (88%) and accuracy (87%). Moreover, the proposed GA method has the highest level of interpretation, is easy to understand and provides feedback to analysts.  相似文献

Microfinance and its “reinvention as bankers-for-the-poor” to create financial inclusion has not been effective everywhere. The literature seems to suggest that the social economy and microfinance help marginalized business people; yet no one considers that political bias interferes with the social economy, making it hard for it to be just. The promise of micro-credit was to achieve a double bottom line: first, the financial sustainability of the lending institution itself, and second, the social benefit of providing loans to low-income business people. Yet, alternative pitches of a social economy to “help people” fail to analyze the embedded power dynamics within the social economy. In this case study in downtown Kingston, Jamaica, 233 small-business people who depend on development finance because of social exclusion now find that these targeted programs are intertwined in partisan, sometimes dangerous, politics. As a result, oppressed people opt out of micro-banking programs to resist “Big Man” politics – the politicians or gangsters attempting to control them. In this study of 307 interviews, I analyze the informal politics of Dons and politicians who misuse micro-credit for their own ends. I find that the coupling of class biases and clientelist practices in the social economy discourages eligible business people from taking micro-loans, and argue that the microfinance industry needs to pay close attention to this issue if it is to continue to help marginalized business people.  相似文献

This article seeks to evaluate the appropriateness of a variety of existing forecasting techniques (17 methods) at providing accurate and statistically significant forecasts for gold price. We report the results from the nine most competitive techniques. Special consideration is given to the ability of these techniques to provide forecasts which outperforms the random walk (RW) as we noticed that certain multivariate models (which included prices of silver, platinum, palladium and rhodium, besides gold) were also unable to outperform the RW in this case. Interestingly, the results show that none of the forecasting techniques are able to outperform the RW at horizons of 1 and 9 steps ahead, and on average, the exponential smoothing model is seen providing the best forecasts in terms of the lowest root mean squared error over the 24-month forecasting horizons. Moreover, we find that the univariate models used in this article are able to outperform the Bayesian autoregression and Bayesian vector autoregressive models, with exponential smoothing reporting statistically significant results in comparison with the former models, and classical autoregressive and the vector autoregressive models in most cases.  相似文献

The transportation system affects all aspects of our daily lives including relatively long-term decisions on work and home location choice and automobile ownership decisions. The interdependency existing among these three decisions jointly influences household mobility and overall travel patterns. Therefore, a dynamic modeling framework that can account for the effects of interdependencies between vehicle transaction behavior and residential and job location choices is highly desirable. These decisions are made in the household level while individuals’ decisions influence the overall outcome; therefore, it is also important to incorporate a group decision making process within such modeling frameworks.This study introduces a dynamic model for vehicle ownership, residential mobility, and employment relocation timing decisions. These decisions are modeled at the individual level and then sequentially aggregated to the household level if it is required. A hazard-based system of equations is formulated and applied in which work location and residential location changes are included as endogenous variables in the vehicle transaction model while other important factors such as land-use and built environment variables, household dynamics, and individuals’ socio-demographics are also considered.  相似文献

The objective of this study is to explore the feasibility of identifying factors that could presage the imposition of exchange controls. Two sets of variables are argued to contain pertinent information regarding the imposition of controls. One set is composed of 14 economic ratios related to the balance of payments and exchange rate; the other set is made up of 17 proxy measures of sociopolitical instability. The empirical analysis of exchange controls imposed by 13 governments during 1973–1983 shows that these variables have potential for predicting the imposition of exchange controls.  相似文献

Abstract

The purpose of the research is to examine the effect of the two different teaching approaches in the first accounting course on student performance in a subsequent finance course. The study compares 128 accounting and finance students who took introductory financial accounting by either a user approach or a traditional preparer approach to examine their academic performance on a subsequent finance course. The results indicate that there is no significant difference in the finance course grade between students who took the traditional introductory accounting course and students who were taught under the user approach. These findings support the argument that the user approach has no impact on subsequent finance course grade and either method can be used to teach introductory financial accounting. Three factors were found to affect subsequent performance in an introductory finance course: GPA prior to taking the finance course, grades in macroeconomics, and statistics.  相似文献

Price jumps are mostly related to investor reactions to unexpected extreme news. We perform an event study of price movements after jumps to analyse if investors’ reactions are affected by psychological biases. We employ recent non-parametric methods based on intraday returns to separate large price movements that are related to unexpected news from those merely caused by periods of high volatility. In general, we find evidence for irrational pricing, which can be associated with investors’ optimistic behavior in a bull market and the pessimism prevailing in a bear market. Furthermore, our analysis confirms the conjecture that small firms are more subject to speculative trading than large firms.  相似文献
