Reducing injury and death in house fires is an important public health intervention activity with the presence of an operating smoke alarm widely considered an important way of reducing harm from fire. Yet despite a number of initiatives and fire-safety campaigns, a number of households at greater risk of domestic fire fail to have a functioning alarm. This paper provides empirical insight into everyday experiences of owning, maintaining and testing smoke alarms among a purposive sample of individuals identified as being less likely to own a functioning smoke alarm. Analysis from focus group data identifies a number of reasons why individuals may not own or test an alarm, and provides new insight into how fire risk is understood in the context of a range of competing, and potentially more prominent, individual and household risks. We suggest that while initiatives that aim to reduce fire injury and death should be continued, their success, and indeed future research on fire risk, should pay attention to the mundane and everyday contexts within which individuals currently rarely reflect on their risk of experiencing a domestic fire.  相似文献

This study investigates the usefulness of an Australian accounting work‐readiness program as perceived by international accounting graduates. Using logistic regression, the study reports the results of a survey of 186 graduates who completed the program in the period 2010–2013 and are now employed in either accounting or non‐accounting roles. The results show that graduates who were employed in an accounting role perceived internships and critical thinking skills to be the most useful curriculum components of the work‐readiness program in obtaining their employment. The findings have implications for various stakeholders, in particular educators and professional bodies involved in the curriculum design of the work‐readiness program. The government also has an interest in the value of this program as they grant visas for international students to study in Australia and fill a skills shortage in the profession. The results also provide insights for other Western economies that attract large numbers of international graduates as skilled migrants.  相似文献

Academics and practitioners frequently highlight that overall market and industry performance is an important aspect of a firm’s profitability. However, few studies allow for the decomposition of a firm’s profitability into market, industry, and idiosyncratic components, and those that do often assume that the market and industry components are cross-sectional constants. In this study, we allow for variation in firm-specific sensitivities to market, industry, and idiosyncratic economic shocks, and then assess whether and when this decomposition results in improved forecasts of profitability. For the overall sample, we find significant improvements in terms of the magnitude of forecast errors and the frequency with which forecasts based on the decomposed values are superior versus forecasts using only total profitability. Across the sample as a whole, decomposing profitability in the forecasting process results in more accurate forecasts greater than two-thirds of the time (increasing to almost 80% within certain subsamples). Our results provide strong support for the role that firm-specific measures of market and industry profitability play in predicting a firm’s future performance, as well as highlighting settings where the decomposition provides the greatest benefit in terms of predicting future changes in profitability.  相似文献

Productivity spillovers from multinational corporations (MNCs) to local firms have been an area of keen research interest in developing economics. Claims of positive spillovers in the form of technology transfers have been questionable, in part because of the many ambiguous conclusions obtained. The paper argues that the lack of focus in the mechanisms underpinning spillovers may be one of the reasons for the ambiguity. Using local input–output linkages as the mechanism for technology transfer, this study examines the presence and the enabling conditions for spillovers. Accounting for the variations in firms' characteristics, the findings show that skills‐oriented MNCs participating in international production networks transmit horizontal spillovers to local establishments. Vertical spillovers from MNCs are mostly relevant only to lower‐skilled establishments. For skilled and export‐oriented local establishments, technologies learned from producing for international production networks are more significant than forming linkages with MNCs in the domestic market.  相似文献

Protected areas are key to the conservation of global biodiversity and ecosystem services; however, their success is contingent upon adequate funding. One possibility to increase funding for park management is to “sell” a wider suite of ecosystem services “produced” by protected areas, such as carbon sequestration. We conducted 420 tourist surveys to analyze willingness to pay (WTP) for ecosystem service benefits via a conservation fee in the Tambopata National Reserve in Peru. We also interviewed eight tour operators about their perceptions of the proposed fee. The average stated WTP was 15 USD. Sixty-six percent of tourists stated they would pay 10 USD or more, which, if actually paid, would have resulted in 318,000 USD for park management in 2015. Most respondents stated they would pay an additional fee if it supported biodiversity conservation or local ecosystem services, such as water, but less than 10% of tourists were motivated by carbon sequestration as a reason to pay the fee. Most tour operators supported the additional fee. Our findings suggest that tourists are willing to pay higher fees to support conservation but that interest in paying for additional ecosystem services from parks may not extend to global and intangible benefits such as carbon sequestration.  相似文献

The last several decades have seen increases in patenting activity worldwide, as well as growing issues related to patent quality. In response to these quality issues a recent patent literature has emerged, that investigates the behavior and incentives of patent examiners, applicants, and third parties. In this paper, we provide an overview of patent procedures, patent systems and a survey of the new economic literature on patent systems. Both theoretical and empirical papers are considered. Policy implications coming from this literature are presented.  相似文献

In about 20%–30% of cases where an analyst revises two outputs (namely, earnings estimates, target prices, or stock recommendations) simultaneously, the two estimates are revised in opposite directions. Existing literature notes that these inconsistent outputs are widespread, and concludes that they are lower-quality, driven by strategic bias, and are viewed as less valid by investors. We find that these characterizations are generally inaccurate. Apparent inconsistency is largely driven by accounting and economic factors, with only limited evidence that investment banking-related conflicts play a role. Moreover, inconsistent outputs are neither less accurate than consistent outputs nor do they resolve less investor uncertainty upon their release. Overall, our results suggest that researchers should be cautious in interpreting the correlation between analyst outputs as a measure of bias or quality, and in using a single analyst output as a proxy for an analyst's overall views.  相似文献

Real estate investment portfolios of financial institutions have seen dramatic changes over the last three decades or more. Historically such property investment decisions have been seen within a portfolio diversification paradigm that has sought to balance risk and return. This paper considers the role of the supply of assets in the determining and constraining the UK institutional portfolio. The supply of real estate assets not only expands during property booms but has also been transformed by a long term urban development cycle as cities adapt to cars and the ICT revolution that has brought new property forms. The research examines long term trends in investment change by disaggregating into ten property forms rather than the usual three land use sectors. It then assesses to what extent investment patterns can be explained in terms of portfolio theory, short term net returns of individual sectors or driven by the supply of real estate assets. It concludes that the supply of real assets is an overlooked explanation.  相似文献

We add to the literature on the association of financial knowledge and financial attitudes with financial outcomes by focusing on predominantly low-income Hispanic families. We examine (i) saving for emergencies, for college, and in 401(k) plans, and (ii) ownership of a home, land or rental property, and an investment account. We find that financial knowledge is strongly related to our savings measures and to owning an investment account. Financial attitudes play less of a role, but assume some importance when interacted with financial knowledge. Self-reported financial knowledge in addition to factual financial knowledge is associated with favorable financial outcomes. Our results are important for the upward economic mobility of a demographic group that has received less attention in the literature.  相似文献
