The effectiveness of information interventions to improve domestic food safety among rural consumers

Consumer education on food handling behavior is regarded as an effective method to improve domestic food safety and prevent foodborne illness, but is usually overlooked in rural areas. Using a presurvey and two rounds of postsurveys targeted at rural consumers from China included in a randomized controlled trial, this study investigated the effectiveness of two information interventions—a leaflet with tips for best practices and the leaflet plus consumer education sessions conveyed by phone—and compared them with a control group. Cloth use behavior was the target in the trial and five specific aspects were evaluated: (1) whether the cloth was made of old clothes, (2) whether the one used to clean kitchen tables was also used to wash dishes, (3) whether it was hung to dry, (4) how it was disinfected, and (5) how long the cloth was used before being discarded. Firstly, consumers' behavior was scored by summing the above-mentioned five behaviors. The results estimated using the difference-in-difference model showed that respondents in the leaflet-only group improved to a greater extent than those in the control group, but their difference in progress was not statistically significant until the second round of the postsurvey. Respondents in the leaflet-plus-phone group were quicker to adopt suggested practices and made discernible improvements compared with those in the leaflet-only group in the first round of the postsurvey, but the gap between these groups narrowed to statistically insignificant in the second round of the postsurvey. It was concluded that one consumer education session was effective and made a difference in the long term, whereas more education sessions produced normative behavior at faster rates, showing a significant improvement in the short term. Then, the study estimated the effectiveness of interventions on the five specific behaviors separately. The results were estimated using a probit difference-in-difference model and showed that the suggested behaviors with lower costs or a greater difference from past behaviors were more likely to be adopted by consumers. Consumer education facilitates proper food handling practices among rural households, which should be considered by policy makers.

Macroeconomic stabilization through monetary and fiscal policy coordination: Implications for European Monetary Union

In a two-country model, we consider the implications of monetary and fiscal policy coordination for macroeconomic stabilization. We show that the optimal regime is one of monetary and fiscal policy coordination under flexible exchange rates. In the context of the European Community, this suggests that the desire to fix exchange rates may not be costless. In addition, we show that fiscal coordination requires a relatively high degree of flexibility in fiscal policy. This result suggests that limits on the flexibility of fiscal policies, as suggested in the Delors Report, may hinder macroeconomic stabilization.     

Scarcity of safe assets,inflation, and the policy trap

A goal of this paper is to make sense of the seemingly puzzling behavior of interest rates and inflation – and the role of central banks in that behavior – during and after the Great Recession, particularly in the United States. To this end, we construct a model in which government debt plays a key role in exchange, and can bear a liquidity premium. If asset market constraints bind, then there need not be deflation under an indefinite zero interest rate policy (ZIRP). Further, ZIRP may not be optimal under these circumstances. A Taylor-rule central banker could be subject to a ZIRP trap and persistently undershoot target inflation. As well, a liquidity premium on government debt creates additional Taylor rule perils, because of a persistently low real interest rate. We make a case that this is the key policy predicament currently faced by many central banks in the world.     

Reputation,risk-taking,and macroprudential policy

This paper examines the role of macroprudential capital requirements in preventing inefficient credit booms in a model with reputational externalities. In our model, unprofitable banks have strong incentives to invest in risky assets when macroeconomic fundamentals are good in order to avoid the stigma of being assessed as low ability by the market. We show that across-the-system countercyclical capital requirements that deter such gambling are constrained optimal when fundamentals are neither extremely weak nor extremely strong.     

Macroprudential policy and imbalances in the euro area

Since its creation the euro area suffered from imbalances between its core and peripheral members. This paper checks whether macroprudential policy applied to the peripheral countries could contribute to providing more macroeconomic stability in this region. To this end we build a two-economy macrofinancial model and simulate the effects of macroprudential policy (regulating the loan-to-value ratio) when the core and the periphery are exposed to asymmetric shocks. We find that macroprudential policy is able to substantially lower the amplitude of credit and output fluctuations in the periphery. However, for the policy to be effective, it should be decentralized. Very similar conclusions hold when welfare is considered as the optimality criterion.     

Ethical dilemmas: Teaching futures in schools

Educational policy is implicitly futures oriented, yet in most instances fails to engage learners with explicit futures tools and concepts at a school level. Futures studies in education, or futures education has the potential to reposition learning as purposeful and mobilizes the lives of participants by connecting the curriculum of schools with the multifaceted futures of learners. This is a complex task within the tensions often existing between: the cultural role of a school, the expectations of a society, the expertise of teachers, and the increasingly diverse needs of learners (Bateman, 2012). It is between the tensions of these things that the ‘ethical’ issues of what is taught, or omitted as content in a classroom and the consequences of these choices are evident.This paper highlights ethical and moral dilemmas, as they were apparent in two futures education projects. In the first study, the teachers discuss the inherent limitations of offering a broader and more futures oriented curriculum. In the second study, teachers reflect upon their students’ anxiety with regards to futures images as they are interrogated within a curriculum study. Each of these studies highlights the ethical challenges that arise, when possible, preferable and probable futures are developed as part of learning in school settings, which are culturally and demographically diverse.Tirri and Husu (2002) highlight the ethical dilemmas, which emerge in classrooms around the world, based on conflicts in values and competing intentions between key stakeholders. In the studies which contribute to this discussion, there is evidence to suggest that futures thinking causes conflict within an individual's perception of how the world should be, or their worldview as a result of futures imagining which goes beyond what is taken for granted, or is an assumed future eventuality. In the same way, Carrington, Deppeler, and Moss (2010) argue that all curriculum choices about what is taught (or not taught) in a classroom reflect an ethical decision made by a teacher, with regards to what is foregrounded for learning and what is omitted.It is crucial to re-examine the role of a school in educating students for their futures, as opposed to educating students with an aim of furthering governmental agendas. More significantly, however, as this paper highlights, it is exploring the boundaries of what is acceptable or unacceptable, appropriate or inappropriate to teach in a classroom, given the changing diversities of schools and education systems throughout the world.
