我国29个省市区利用外国直接投资的空间效应:1985-2007年

本文借鉴近年来兴起的主流空间统计分析方法,对1985-2007年期间我国29个省市区实际利用外资的空间自相关性进行了研究,并测量了空间集聚效应和空间辐射效应。研究结果表明:自1989年以来,我国29个省市区实际利用外资存在空间自相关性;从空间集聚效应来看,空间集聚逐渐从珠三角、长三角向环渤海地区扩散,从东部沿海地区向中部地区扩散,与我国对外开放的格局基本保持一致;从空间辐射效应来看,具有正向辐射效应的高高集聚型省市区日益集聚在东部和中部地区,具有负向辐射效应的低低集聚型省市区日益集聚在西部地区。     

The impact of maize price shocks on household food security: Panel evidence from Tanzania

Using three waves (2008/09, 2010/11, 2012/13) of the Tanzanian National Panel Survey, this study investigates the impact of maize price shocks on household food security. Between 2008/09 and 2012/13, calorie intake stagnated for urban households, yet sharply deteriorated for rural households. The latter was driven by a significant decline in the consumption of the major staple maize which showed strongest price hikes among all major food items. Fixed-effects regressions indicate a clear negative relationship between maize prices and average household energy intake. Almost all population groups were found to be negatively affected by maize price shocks, with rural landless households being the most vulnerable group. In particular, a 50 percent rise in maize prices decreases caloric intake for rural (urban) households on average by 4.4 (5.4) percent, and for rural landless households by 12.6 percent. Results further indicate that subsistence agriculture can act as an effective strategy to insure against food price volatility.     

Post-SARS tourist arrival recovery patterns: An analysis based on a catastrophe theory

In 2003, the Severe Acute Respiratory Syndrome (SARS) ravaged many Asian countries. The outbreak of SARS caused a crisis in the tourism industry in many parts of Asia in that year. The purpose of this study is to examine and to compare the post-SARS recovery patterns of inbound arrivals from Japan, Hong Kong and USA in Taiwan. Taking the cusp catastrophe model as its foundation, this study proposes a well-grounded approach to understanding the nature of the recovery processes and to explaining the difference between the recovery patterns displayed by arrivals from Japan and those from Hong Kong and USA. Implications regarding tourism promotion policies are drawn from the analysis.     

Involvement theory in constructing bloggers' intention to purchase travel products

Blogs recently have demonstrated their enormous marketing potential, and more and more travel advertisements are being posted in blogs. In light of this observation, this study aims to provide insights into the structural relationship among travel bloggers' involvement level, the advertising effect from blog messages, and travel bloggers' intention to purchase travel products. A travel blogger's purchase intention model was constructed and empirically tested. A total of 900 questionnaires were distributed to identified travel bloggers; 398 valid responses were returned. The data were examined with Structural Equation Modelling (SEM). The results demonstrated the positive impact resulting from the ad effect as well as the ad effect on purchase intention, which could be verified in travel blog environments. It also indicated that high-involvement travel bloggers are more likely to form favourable impressions with regard to ads in travel blogs. Travel blogs play a positive role in the processing of ad messages; brand management is essential to business marketers since brand attitude is the most influential factor related to the ad effect on purchase intention. Meanwhile, while ad attitude is not significantly effective concerning purchase intention, it remains essential in forming brand attitudes. Several implications for posting advertisements in travel blogs will be discussed and suggested in this paper.     

Optimal dynamic reinsurance with dependent risks: variance premium principle

In this paper, we consider the optimal proportional reinsurance strategy in a risk model with two dependent classes of insurance business, where the two claim number processes are correlated through a common shock component. Under the criterion of maximizing the expected exponential utility with the variance premium principle, we adopt a nonstandard approach to examining the existence and uniqueness of the optimal reinsurance strategy. Using the technique of stochastic control theory, closed-form expressions for the optimal strategy and the value function are derived for the compound Poisson risk model as well as for the Brownian motion risk model. From the numerical examples, we see that the optimal results for the compound Poisson risk model are very different from those for the diffusion model. The former depends not only on the safety loading, time, and the interest rate, but also on the claim size distributions and the claim number processes, while the latter depends only on the safety loading, time, and the interest rate.     

The Effect of the Alternation in the Ruling Party on Three-Factor Risks and Returns in ETF: The Case of Presidential Elections in Taiwan

This study discusses the effect of alternation in the ruling party in presidential elections on three-factor risks and returns of the three main exchange-traded funds (ETFs) in Taiwan, which has an unclearly defined international status and whose citizens have the right to vote directly for the president. We find that after the ruling party has been determined, in the period between Election Day and inauguration day, both the stock market and ETFs show a slight rise in prices. This suggests that most investors are initially optimistic after the election results have been announced. Meanwhile, the reverse book-to-market risk value deteriorates significantly. These results indicate that political uncertainty increases the risk premium of market factors and reverse book-to-market factors for some ETFs.     

Revisiting Border Effect: Evidence from Taobao.com in China

Inherent home bias and trade barriers (particularly local protectionism in China), which are difficult to separate, are two main explanations of border effect. We attempt to solve this problem by analyzing online trade. Different from offline trade, inherent home bias is the only cause of online border effect because local governments are usually unable to restrict online trade. Thus, the difference between the border effect in online and offline trade can be reasonably interpreted as the existence of government protectionism in the offline market. We find a statistically significant difference between online and offline border effects in China, which can be interpreted as strong evidence that policy barriers remain significant and hinder interregional trade.
