Stability and bifurcation in a simple heterogeneous asset pricing model

Stability and bifurcation analysis of deterministic systems has been widely used in modeling financial markets. We develop a simple pricing model with two types of rational traders, fundamentalists and chartists, in order to study well price behavior in financial markets, we use student t distribution to replace traditional normal distribution to describe fundamental price process. We study the stability and bifurcation of the underling deterministic system and use numerical simulation to study the dynamic of the stochastic system, including autocorrelations structures and high kurtosis of the returns. It is found that the fundamental price becomes stable (unstable) when the activities from both types of traders are balanced (unbalanced).

民营企业的政治资源与民营企业多元化投资——以中国民营企业500强为例

This paper argues that the political resources owned by Chinese private enterprises affect their diversification strategy under the context of China’s transitional economy. Based on the sample of top 500 private enterprises in 2004 in China, we find the following empirical evidence: First, political resources owned by private enterprises are positively and significantly related to their degree of diversification. Second, the possibility for private enterprises to diversify their business by entering industries under government regulation is positively related to their political resources. Third, the possibility of related diversification for private enterprise is negatively related to its political resources.

Demographic Change and Policy Responses: Implications for the Global Economy

The fertility declines associated with the final phase of the global demographic transition have led to slower population growth and accelerated ageing in developed countries and in several advanced developing countries. A global demographic and economic model is used to assess the implications of these changes for population sizes, age‐gender distributions, labour force growth and their implications for economic performance. A baseline projection that incorporates declining fertility is compared with a hypothetical constant population growth scenario. The results show that slower population growth and ageing reduces average saving rates in industrial regions, yet global investment demand is also slowed and saving rates rise in developing regions, so there is no net tightening of financial markets. Increased aged labour force participation, considered one solution to the resulting rise in aged dependency in advanced regions, is found to redistribute investment in favour of the industrialised regions and hence to accelerate their per capita income growth, while conferring on the other regions compensatory terms of trade improvements. The alternative of replacement migration is found to require inconceivably large population movements. It also impairs real per capita growth in destination regions but by least in Western Europe, where the terms of trade are improved by the immigration.
