This study uses secondary data from a four-wave repeated cross-sectional survey to examine communication channel usage patterns and their effects on health knowledge acquisition during the different phases of the 2009 H1N1 crisis in Beijing, China. The results suggest that channel choice, particularly for mobile phone and interpersonal communication, varies as a function of different levels of threat during a crisis. Moreover, social groups like students, retirees, and professionals differed in their channel selection. The study concludes that television users have more H1N1 knowledge than non-users and that in most cases, interpersonal communication does not contribute to knowledge gains. The theoretical implications are discussed at the end.  相似文献

The outbreak of the pandemic influenza H1N1 2009 (swine flu) between March and April 2009 challenged the health services around the world. Indeed, misconceptions and worries have led the public to refuse to comply with precautionary measures. Moreover, there have been limited efforts to develop models incorporating cognitive, social‐contextual, and affective factors as predictors of compliance with recommended behaviors. The aim of this study was to apply a social‐cognitive model of risk perception and individual response to pandemic influenza H1N1 in a representative sample of Italian population. A sample of 1,010 Italians of at least 18 years of age took part in a telephone survey. The survey included measures of perceived preparedness of institutions, family members and friends’ levels of worry, exposure to media campaigns (social‐contextual factors), perceived coping efficacy, likelihood of infection, perceived seriousness, personal impact, and severity of illness (cognitive evaluations), affective response and compliance with recommended behaviors. Results demonstrated that affective response fully mediated the relationship between cognitive evaluations and social‐contextual factors (with the exception of exposure to media campaigns) and compliance with recommended behaviors. Perceived coping efficacy and preparedness of institutions were not related to compliance with recommended behaviors.  相似文献

This paper provides a tool to build climate change scenarios to forecast Gross Domestic Product (GDP), modelling both GDP damage due to climate change and the GDP impact of mitigating measures. It adopts a supply-side, long-term view, with 2060 and 2100 horizons. It is a global projection tool (30 countries/regions), with assumptions and results both at the world and the country/regional level. Five different types of energy inputs are taken into account according to their CO2 emission factors. Full calibration is possible at each stage, with estimated or literature-based default parameters. Compared to other models, it provides a comprehensive modelisation of Total Factor Productivity (TFP), which is the most significant determinant of the GDP projected path. We present simulation results of different energy policy scenarios. They illustrate both the “tragedy of the horizon” and the “tragedy of the commons”, which call for a policy framework that adequately integrates a long run perspective, through a low-enough discount rate and an effective intergenerational solidarity as well as international cooperation.  相似文献

The paper provides an overview and assessment of an emerging literature on the psychology and behavioural economics of poverty. We particularly highlight poverty experiences, role of neighbourhoods, poverty dynamics and transmission, child poverty and disability and personal finance. In addition we consider psychology and policy responses by looking and autonomy and empowerment, and poverty reduction programs. Our central thesis is that the detailed knowledge of individual experiences, cognitions and social factors in psychology and related social science complements the traditional economic emphasis on structural factors and policy instruments in a way that is exemplified by emerging work in behavioural economics. We conclude it is increasingly recognised that poverty reduction policies which are informed by behavioural insights may, as a result, be more effective.  相似文献

This paper presents a political economy theory of fiscal policy and unemployment. The underlying economy is one in which unemployment can arise but can be mitigated by tax cuts and increases in public production. Such policies are fiscally costly, but can be financed by issuing government debt. Policy decisions are made by a legislature consisting of representatives from different political districts. With the available policies, it is possible for the government to completely eliminate unemployment in the long run. However, with political decision making, the economy always has unemployment. Unemployment is higher when the private sector experiences negative shocks. When these shocks occur, the government employs debt‐financed fiscal stimulus plans which involve both tax cuts and public production increases. When the private sector is healthy, the government contracts debt until it reaches a floor level. Unemployment levels are weakly increasing in the economy's debt level, strictly so when the private sector experiences negative shocks. Conditional on the level of workers employed, the mix of public and private output is distorted.  相似文献

This paper examines the effects of stronger child support enforcement and declines in welfare benefits on changes in non-marital childbearing between 1980 and 1996. Economic theory suggests that stricter child support enforcement will increase the costs of children for unwed fathers, making them less likely to have a child outside marriage. Reductions in welfare benefits also are expected to increase the costs of non-marital childbearing for both mothers and fathers. We examine these hypotheses, using aggregate state-level data and fixed effects regression models to identify the effects of policies on non-marital birth rates. We find that both stricter child support enforcement and declines in welfare benefits deter non-marital births. However, the estimated effects of child support enforcement are more robust and larger than those of welfare. The estimates imply that in the 1980–1996 period, increases in child support enforcement led to a decline in non-marital birth rates in the range of 6% to 9%, whereas decreases in welfare benefits led to a decline in the range of 2% to 4%.

We investigate induced retirement effects of the Norwegian early retirement program AFP and emphasize effects caused by relocations of some individuals from disability pension and unemployment to AFP. Theoretical considerations predict that AFP unambiguously induces more early retirement. Analyzing Norwegian register data 1994–96 with parametric and non-parametric methods, we demonstrate that i) economic incentives influence the retirement decision, ii) there is a significant net induced retirement effect, iii) by a conservative judgment, at least 50% of the AFP retirees would have stayed in the labor force without the scheme.All correspondence to Espen Bratberg. We are indebted to the referees for detailed remarks, which significantly improved the paper. Financial support from the Norwegian Research Council and the Ministry of Health and Social Affairs is greatly appreciated.

A Eurobarometer survey from 2007 reports that most undeclared work in the EU 27 takes place in the three most high-trusting and non-corrupt countries—Denmark, Sweden and the Netherlands. This is somewhat surprising since social trust is normally associated with economic outcomes that are beneficial to society. The aim of this paper is to test whether undeclared work is a dark side of social trust. Since the Eurobarometer data may contain inaccurate self-reports on undeclared work and social trust may affect the willingness to provide truthful answers, we use more appropriate data in our test. Specifically, we use data from one single country (Danish Values Studies, 1999/2008) and undeclared work morale as an indicator of actual undeclared work—where undeclared work morale is the degree to which a person thinks undeclared work is wrong. We find a significant negative relationship between social trust and undeclared work morale after adjusting for a number of important controls. Thus, the evidence is in line with the bivariate picture of the Eurobarometer survey and suggests a dark side of social trust. We provide some initial explanations.  相似文献

This paper investigates the short‐term effects of fiscal consolidation on economic activity in OECD economies. We examine contemporaneous policy documents to identify changes in fiscal policy motivated by a desire to reduce the budget deficit and not by responding to prospective economic conditions. Using this new dataset, our estimates suggest that fiscal consolidation has contractionary effects on private demand and GDP. By contrast, estimates based on conventional measures of the fiscal policy stance used in the literature support the expansionary fiscal contractions hypothesis but appear to be biased toward overstating expansionary effects.  相似文献
