Can Insurance Activity Act as a Stimulus of Economic Growth? Evidence from Time-Varying Causality in China

This article investigates the nexus between insurance and economic growth in China with a dynamic interactive mechanism to study different time periods. Using quarterly data from 1999 to 2015, the rolling-window causality test provides evidence of bidirectional causality between insurance activity and economic growth. However, the “supply-leading” pattern tends to dominate the “demand-following” pattern, which implies that in China insurance acts as a stimulus of economic growth during most of the period. Property insurance is more effective than life insurance in stimulating economic growth. Some temporary negative impacts from the development of the insurance sector show that China is in the midst of a transition from a closed economy to a more open economy and policy interventions by the government to liberalize the insurance sector. These findings offer several useful insights for policy makers in transition economies and developing countries.     

The Importance of taste in experimental auctions: consumers’ valuation of calorie and sweetener labeling of soft drinks

A majority of purchases that consumers make are classified as repeat purchases. One of the main reasons why consumers make repeat food purchases is the food's taste. Therefore, we examined the importance of including taste testing in nonhypothetical experimental auctions. Specifically, we used two experiments to determine consumers’ willingness to pay for soft drinks labeled with different calorie and sweetener information. In Experiment 1, participants tasted the soft drinks prior to the bidding rounds. In Experiment 2, participants did not taste the soft drinks prior to the bidding rounds. Bidding behavior for the soft drinks was significantly different between Experiment 1 and Experiment 2. Results suggest that including taste testing in the design of experimental auctions is important to accurately capture consumers’ willingness to pay for foods that are purchased repeatedly. Results also imply that policies aimed at combating obesity by making the calorie content of foods more visible may not produce desired outcomes.     

中国不同省份金融结构转变与产业结构升级关系的实证研究

随着我国社会主义市场经济改革的不断深入，现有金融结构已不能适应经济发展。本文从金融结构调整的角度出发，对中国较发达地区，欠发达地区以及基于全国的数据进行面板回归。通过对实证结果的分析，得出金融结构调整对产业结构调整并不是简单线性关系的结论，金融结构调整应有合理的范围，当金融结构在其范围内变化时，能够促进经济的增长，当金融结构的调整超过合理范围时，金融功能的负作用会逐渐增强，当负作用积累到一定程度，会对经济的发展起到阻碍作用，我国各省份应根据自己的实际发展情况和自然禀赋，选择合适的金融结构和经济发展模式。

Extreme risk spillovers between crude palm oil prices and exchange rates

This study is the first attempt to examine the extreme risk spillovers between Malaysian crude palm oil (CPO) and foreign exchange currencies of the three largest CPO importers: India, the European Union and China throughout the global financial crisis. Using daily data of three currencies, CPO spot and futures from 2000 to 2018, our results show: First, before the crisis, the unexpected change in foreign exchange rates is the primary driver of risk spillover to the CPO market. Second, during the crisis, the extreme movement of CPO spot returns is dominant in the Malaysian exchange rates relative to the euro. Third, after the crisis, the spillover flows from the CPO market to the foreign exchange market. Overall, our findings show the importance of CPO pricing dynamics in mitigating foreign exchange risk over the crisis period. This paper contributes to the extant literature by recognizing the effect of risk spillover on the targeted foreign exchange rate for portfolio allocation.     

On the tourism-led growth hypothesis in the UAE: a bootstrap approach with leveraged adjustments

The emerging market of the UAE has chosen attracting international tourism as one of the main strategies during the recent decades in order to diversify its economy. The main goal has been to achieve sustainable growth without overreliance on the volatile oil sector. This article investigates the impact of tourism on economic performance in the UAE by using bootstrapped causality tests with leverage adjustments. The results show that the tourism-led growth hypothesis can be supported empirically. Thus, the conducted policy by the UAE government to promote international tourism for achieving economic growth might be considered as a sustainable strategy.     

Does US news impact Asian emerging markets? Evidence from nonparametric causality-in-quantiles test

This paper aims to analyze whether US news on inflation and unemployment causes returns and volatility of seven emerging Asian stock markets from 1994 to 2014, by employing the causality-in-quantile approach. We find evidence that US news affect returns and/or volatility of all the seven stock markets considered, with these effects clustered around the tails of the conditional distribution of returns and volatility when they are either in bear or bull modes. In general, our results highlight the importance of modeling nonlinearity and studying entire conditional distributions of stock returns and volatility to draw correct inferences.     

Does Medical Equipment Expansion Lead to More Diagnostic Services? Evidence from China’s Sichuan Province

A major goal of China’s healthcare reform is to control the increasing healthcare spending, much of which can be attributed to the overuse of diagnostic tests and has been relatively less studied in the literature. This article analyzes the correlation between medical equipment expansion and the increase in diagnostic test expenditure in China, using Sichuan Province as an example. County-level data aggregated from hospitals’ annual reports in Sichuan Province from 2008 to 2012 were used. The results show a positive correlation between the expansion of medical equipment and the increase in diagnostic test expenditure. Our study provides implications on reforming China’s healthcare delivery system and medical equipment regulation policies.     

新型城镇化对产业升级的影响效应分析

我国新型城镇化已成为经济新常态下产业升级的新思路，新型城镇化进程产生的诸多绩效是产业升级的强大动力。本文系统阐述了新型城镇化影响产业升级的作用机理，并基于数据可得性以带状选取东中西部各3个省份，每个省选取3个中大型地级市2004~2015年的面板数据作为研究样本，将新型城镇化和产业升级之间关系图和格兰杰因果检验结合，从时间和空间角度分析新型城镇化对产业升级的影响。结论表明：在时间上，2005~2011年，两者有负相关关系，2011~2015年，两者有正相关关系；在空间上，东部新型城镇化对产业升级有正向影响，中西部前者对后者无正向影响。根据实证结果和新型城镇化对产业升级的影响在时间和空间上存在差异的原因进而提出相关对策建议。
