中日电气及电子类产品内贸易指数分析

在经济全球化和技术进步推动下,产品内贸易日益成为国际贸易的主要形式.中日贸易中电气及电子类产品内贸易占主导,并日趋活跃.运用产品内贸易指数、竞争力指数等指数对中日电气及电子类产品内贸易进行深入分析.发现两国产品内贸易已达到相当高的水平,但是中国零部件的竞争力水平不高,局限于组装优势,仍处于生产价值链低端.因此,中国如何利用国际产品内分工,发挥自身优势,延伸价值增值链,促进中日电气及电子类产品贸易结构升级,乃是当务之急.

The influence of oil price uncertainty on stock liquidity

Using high-frequency intraday data, this study provides strong empirical evidence that elevated oil price uncertainty has a significant and negative influence on stock liquidity. More specifically, the results suggest that large oil-related corporations are most affected, followed by small-listed firms more generally. Further analysis reveals that liquidity providers widen the bid-ask spreads to protect themselves during periods of high oil price uncertainty for large-listed firms, particularly those in the oil industry. These findings are robust to various measures of oil price uncertainty, different market conditions, structural break analysis and show the influence of oil price movements extends to stock liquidity.     

Uniform pricing effect: The influence of uniform pricing on product value judgement and purchase intention

Uniform pricing, which is a pricing strategy that sets a unified price for all products in the store or all products in the same category, is becoming increasingly popular over the past decades. However, scarce attention has been paid to investigating its impact on consumer behaviour. This research investigates the influence of uniform pricing on product value judgements and purchase intentions. Four studies demonstrate that uniform pricing (vs. non-uniform pricing) could induce stronger promotion perception, which leads to more positive product value judgements and purchase intentions. Moreover, price sensitivity and product involvement moderate this effect, and this effect only exists for high price-sensitive consumers and low product involvement consumers.     

Health shocks and mortgage debt payoff among American homeowners over age 50: A survival analysis

Mortgage debt is financially burdensome for many older homeowners in the United States. As people age, declining health can bring about increased healthcare costs. Focusing on homeowners aged 50 and older in the U.S., we investigate two research questions: (1) To what extent does a heath shock affect the likelihood of paying off a mortgage voluntarily or involuntarily? and (2) how long does a health shock delay the time it takes to pay off a mortgage? We used eight biannual waves (2004–2018) of the Health and Retirement Study containing 11,772 borrowers to build survival regression models. Results showed that a health shock reduced the likelihood of voluntary payoff by 12%, while it increased the probability of involuntary payoff by 18%. A health shock delayed voluntary and involuntary payoffs for 30 and 21 months, respectively. We discuss tax deduction and HELOCs as strategies to reduce older homeowners' mortgage strain.     

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.
