This paper examines the impact of foetal exposure to air pollution from agricultural fires on Brazilian students' cognitive performance later in life. We rely on comparisons across children who were upwind and downwind of the fires while in utero to address concerns around sorting and temporary income shocks. Our findings show that agricultural fires increase , resulting in significant negative effects on pupils' scores in Portuguese and Maths in the grade through prenatal exposure. Back-of-the-envelope calculations suggest that a 1% reduction in from agricultural burning has the potential to increase later life wages by 2.6%. 相似文献

Enhanced Special Drawing Rights: How China Could Contribute to a Reformed International Monetary Architecture 下载免费PDF全文
Since the end of the Bretton Woods era, the world has operated on a de facto system of free‐floating exchange rates, with the US dollar as the dominant international currency. The system, characterized by large pro‐cyclical capital flows and chronic imbalances, is inherently unstable, and has contributed to repeated crises, recessions and geopolitical tensions. One potentially “least‐difficult” line of reform would be to allow the evolution of a multi‐currency system, underpinned by an expanded role for Special Drawing Rights (SDRs). Attempts to promote wider use of the SDR have foundered on the liquidity premium. However, for Chinese corporations and institutions, at present restricted in their capital account activities, the SDR liquidity premium would appear less daunting. The Chinese authorities could provide policy encouragement for the use of SDRs by their institutions. This initiative, supported by China's Special Administrative Region Hong Kong, would kick‐start an international SDR ecosystem, and encourage even broader use of SDRs, to the benefit of international monetary stability. 相似文献

In differentiated product markets where consumer preferences are characterized by brand loyalty, an important role for advertising may be to overcome brand loyalty by encouraging consumers to switch to less familiar brands. Using a scanner panel dataset of breakfast-cereal purchases, I find evidence consistent with the hypothesis that advertising counteracts the tendencies of brand loyalty toward repeat purchasing. Equivalently, advertising reduces switching costs in this market. Furthermore, counterfactual experiments demonstrate that in markets with brand loyalty, advertising is an attractive and effective option—relative to alternative promotional activities, such as price discounts—of stimulating demand for a brand . 相似文献

China's urban housing market dynamics suggest that evolving investor confidence may be a relevant demand shifter. Such investors are continually updating their beliefs about the state of the macroeconomy and the policy uncertainty related to national and local housing policies. We build a 35 Chinese city real estate confidence index that varies over time and across cities. This index predicts subsequent house price appreciation and new housing sales. We document evidence of heterogeneous effects of investor confidence depending on a city's demographics and the city's elasticity of housing supply. Our results based on a new household‐level expectations survey bolster the case that investor expectations are an important determinant of real estate price dynamics. 相似文献

During the Soviet era, directors and workers derived mutual benefits from concealing true capacity, hoarding labour and just fulfilling an enterprise's plan. In an environment of labour shortages and guaranteed markets, managers used informal mechanisms to reward and retain good workers given the absence of unemployment and meaningful wage differentials as mechanisms to discipline workers. This cultivated a paternalistic set of relations between enterprise managers and workers, which, it is argued, are being hollowed out in the post-communist era. This is explored in a case study of evolving labour relations in Moldova. Casualization of the workforce has been used as a buffer against greater instability in both the supply of raw materials and demand. Such a strategy has become feasible as enterprises, such as the case-study firm, now have a large pool of external surplus labour on which they can draw. However, paternalism has not been hollowed out completely but rather a split-level realignment is identified. 相似文献

This paper adds to the literatures on socially responsible investment (SRI), investment management, regulation of financial services and social accounting by providing a comprehensive survey of investment methods used in SRI products and regulated social reporting in financial services. Australian and New Zealand regulations require issuers of self‐declarative SRI products to provide details on methods used in portfolio construction. Regulators' objectives to standardize the reporting of portfolio construction and thus improve its comparability were identified by examination of parliamentary debates and other public reports. Portfolio construction styles of 86 SRI products managed by 63 financial institutions in Australia and New Zealand were chosen for analysis. Statistical analysis was conducted to identify associations between styles, construction methods and assessment techniques over a four‐year period: 2004–2007. These aspects were further examined in 18 case studies. Over the period, diversity and intensity of construction methods had increased both within and between investment managers. The non‐standard nature of management consultation used in SRI products, marketing needs to distinguish rather than standardize investment methods and the types of information thought relevant to clients did not reconcile easily with the types of information required by regulation. The more recent products in the sample tended to reference market indexes in portfolio construction, separate social considerations from financial considerations and delegate qualitative assessments of invested companies. Consumer policy implications arise from questions bearing on the integrity of information attached to investment products and the effective monitoring of delegated investment processes.

This paper generalizes existing econometric models for censored competing risks by introducing a new flexible specification based on a piecewise linear baseline hazard, time‐varying regressors, and unobserved individual heterogeneity distributed as an infinite mixture of generalized inverse Gaussian (GIG) densities, nesting the gamma kernel as a special case. A common correlated latent time effect induces dependence among risks. Our model is based on underlying latent exit decisions in continuous time while only a time interval containing the exit time is observed, as is common in economic data. We do not make the simplifying assumption of discretizing exit decisions—our competing risk model setup allows for latent exit times of different risk types to be realized within the same time period. In this setting, we derive a tractable likelihood based on scaled GIG Laplace transforms and their higher‐order derivatives. We apply our approach to analyzing the determinants of unemployment duration with exits to jobs in the same industry or a different industry among unemployment insurance recipients on nationally representative individual‐level survey data from the US Department of Labor. Our approach allows us to conduct a counterfactual policy experiment by changing the replacement rate: we find that the impact of its change on the probability of exit from unemployment is inelastic.

This study empirically investigates the theory that odd‐numbered pricing points can be used as focal points to facilitate tacit collusion. Like other retailers, gasoline stations in the United States disproportionately sell at prices ending in odd digits. I show that station prices are higher and change less frequently in locations using more odd prices (particularly those ending in 5 or 9), even after controlling for other market characteristics. The evidence suggests that the use of pricing points can be an effective mechanism for tacitly coordinating prices, providing an alternative explanation for the widespread use of odd prices in retail markets. 相似文献

Despite widespread uncertainty, if not scepticism, about the precise nature of the expertise that consultants bring to bear in their client engagements, organisations continue to employ consultants in large numbers, especially in information technology-related projects. Drawing on a participant observation study of IT/management consultancy practice, this paper seeks to explore the different ways in which consultants are seen as experts in the light of the pressures of the consultancy market place. The ongoing construction of consultancy expertise through the interaction of consultants and their clients with an array of elements, including technical knowledge, skilled practice, individual and collective experience, and commercial interests is discussed. It is suggested that, rather than being a relatively-enduring property of individuals, based on their mastery of a body abstract knowledge or their skills at managing the perceptions of their clients, the precarious and multi-faceted character of their expertise means that consultants are continuously engaged in its active construction through their situated practice. 相似文献
