This paper studies the connections between the expansion of mining capital, speculative forms of land grabbing and agrarian transformation. It is argued that in periods of commodity boom, the landowning rural elite benefits from mining through speculative land deals with mining companies. They act as ‘land brokers’ for the mining firms, helping them to overcome a significant barrier to land accumulation through the de facto abolition of landed property. The analysis is based on a qualitative case study on the expansion of coal mining in central Cesar in northern Colombia. To develop my arguments, I refer to the concept of accumulation by dispossession as defined by Michael Levien, and historical materialist approaches on rent, and speculative land dispossession. In addition, I use concepts developed for studying coercive land grabbing and agrarian elite participation in armed conflicts to analyse the mechanisms applied to (coercively) acquire rights to land. It is concluded that with high global prices for minerals, metals and fossil fuels, the expansion of mining in the countryside fosters a process of agrarian change through land speculation that is articulated in a reconcentration of landed property, a re-strengthening of the rural landowning elite and the dissolution of peasant agriculture.  相似文献

Anecdotes abound suggesting that the use of predictive analytics boosts firm performance. However, large-scale representative data on this phenomenon have been lacking. Working with the Census Bureau, we surveyed over 30,000 American manufacturing establishments on their use of predictive analytics and detailed workplace characteristics. We find that productivity is significantly higher among plants that use predictive analytics—up to $918,000 higher sales compared to similar competitors. Furthermore, both instrumental variables estimates and the timing of gains suggest a causal relationship. However, we find that the productivity pay-off only occurs when predictive analytics are combined with at least one of three workplace complements: significant accumulation of IT capital, educated workers, or workplaces designed for high flow-efficiency production. Our findings support claims that predictive analytics can substantially boost performance, while also explaining why some firms see no benefits at all.

The interest in Data Envelopment Analysis (DEA) as a method for analyzing the productivity of homogeneous Decision Making Units (DMUs) has significantly increased in recent years. One of the main goals of DEA is to measure for each DMU its production efficiency relative to the other DMUs under analysis. Apart from a relative efficiency score, DEA also provides reference DMUs for inefficient DMUs. An inefficient DMU has, in general, more than one reference DMU, and an efficient DMU may be a reference unit for a large number of inefficient DMUs. These reference and efficiency relations describe a net which connects efficient and inefficient DMUs. We visualize this net by applying Sammons mapping. Such a visualization provides a very compact representation of the respective reference and efficiency relations and it helps to identify for an inefficient DMU efficient DMUs respectively DMUs with a high efficiency score which have a similar structure and can therefore be used as models. Furthermore, it can also be applied to visualize potential outliers in a very efficient way.JEL Classification: C14, C61, D24, M2  相似文献

  • Nonprofit organizations are as susceptible to crisis as any organization as exemplified by Livestrong's attempts to outlive Lance Armstrong's downfall and Planned Parenthood (PP) overcoming Susan G. Komen for the Cure's (SGK) policy to defund organizations under investigation. The public battles held on social media during crises such as these have forced organizations onto new battlegrounds. Supporters for each of these nonprofits proudly shared their thoughts via tweets (e.g. #IstandwithPP) and status updates, as the organizations raced to control the situation. PP had tweeted SGK's policy change creating a bevy of support while sending SGK into a reversal that is still costing racers. Surveys were distributed following Armstrong's performance-enhancing drug use confession and SGK's funding policy announcement to determine attitudes toward giving after organizational crisis. The Theory of Planned Behavior (TPB) was used to assess the strength of attitude, social norms, and perceived behavioral control on the intent to donate to these organizations. The use of TPB expands nonprofit marketing horizons by helping better understand stakeholder intentions and their causes. On the basis of the findings, best practices for nonprofits handling crisis were identified. In particular, organizations need to know their target audiences, know what will make supporters remain, look at crises as opportunities for renewal, be honest, and apologize when appropriate.

Globally, men constitute a larger percentage of smokers than women, but the rate of women smokers is growing. Smoking is a feminist issue: there are unique consequences for women's health, well-being, and agency. Recently passed anti-smoking legislation in Nepal, which has the highest rate of women smokers in South Asia, omits gender-conscious recommendations, potentially diminishing the impact of the legislation on women's lives. Relying on the 2001, 2006, and 2011 waves of the Nepal Demographic and Health Survey, this paper expands the dialogue around women's smoking and places it at the forefront of research on women's health issues. The results indicate that for women in Nepal, formal education and visiting a health facility mitigate smoking behaviors, whereas being employed and living in certain regions promotes smoking behaviors. The aim is for this and the ensuing inquiries to change government anti-smoking legislation in order to improve women's health.  相似文献

Abstract

Prior literature finds that short selling is beneficial to the market because it increases liquidity and helps to discipline optimistic market prices. The authors use 2 controlled experiments to examine the potential for an unintended consequence of allowing short selling or easing short selling restrictions. Because prior research identifies short sellers as sophisticated market participants who have the ability to see through accrual earnings management choices, we predict and find that, when reporting is transparent, managers are more likely to use real earnings management relative to accrual earnings management when short selling restrictions are relaxed. This is consistent with the idea that real earnings management activities are more defensible as the result of legitimate operating decisions and are therefore more likely to hold up to scrutiny from short sellers. Overall, the results suggest that regulations that are unrelated to financial reporting can affect how managers respond to the transparency that arises from financial reporting regulations.  相似文献

This paper develops a framework to measure the exposure to systematic risk for pools of asset securitizations and measures empirically whether current ratings-based rules for regulatory capital of securitizations under Basel II and Basel III reflect this exposure. The analysis is based on a comprehensive US dataset on asset securitizations for the time period between 2000 and 2008. We find that the shortfall of regulatory capital during the Global Financial Crisis is strongly related to ratings. In particular, we empirically show that insufficient capital is allocated to tranches with the highest rating. These tranches account for the greatest part of the total issuance volumes. Furthermore, this paper is the first to calibrate risk weights which account for systematic risk and provide sufficient capital buffers to cover the exposure during similar economic downturns. These policy-relevant findings suggest a re-calibration of RBA risk weights and may contribute to the current efforts by the Basel Committee on Banking Supervision and others to re-establish sustainable securitization markets and to improve the stability of the financial system.  相似文献

We consider a multi-threshold compound Poisson surplus process. When the initial surplus is between any two consecutive thresholds, the insurer has the option to choose the respective premium rate and interest rate. Also, the model allows for borrowing the current amount of deficit whenever the surplus falls below zero. Starting from the integro-differential equations satisfied by the Gerber–Shiu function that appear in Yang et al. (2008), we consider exponentially and phase-type(2) distributed claim sizes, in which cases we are able to transform the integro-differential equations into ordinary differential equations. As a result, we obtain explicit expressions for the Gerber–Shiu function.  相似文献
