Regime Shifts in Asian Equity and Real Estate Markets   总被引:4,自引:0,他引:4  
This paper applies a new statistical technology for identifying regime shifts to analyze recent data on real estate and equity markets in eight developing Far Eastern countries in the 1992–1998 time period. We find that regime shifts in volatility occur in the summer of 1997; however, most of the regime shifts in returns occur in the spring of 1998. While the clustering of regime breaks does not seem to follow any obvious pattern, the country's exposure to trade and firm leverage are important. An analysis of Granger causality suggests that, in most cases, equity returns cause real estate returns but the converse is not true. We also find two-way causality in volatility, suggesting that a common factor drives volatility in these markets. Finally, we provide evidence that the regime shifts generally imply higher relative risk for real estate securities after the estimated breaks.  相似文献

In this paper, we examine the impact of managerial self-interest on the value of multinationality. Since agency theory also suggests that a divergence between the interests of managers and shareholders can be aligned by effective managerial incentive, we also examine the effect of managerial compensation on the value of multinationality. Our results show that for high- Q (Tobin's Q > 1 ) firms, investors do not associate the spending of free cash flow on multinationality with the problem of overinvestments. For high- Q firms, it is also found that the value of multinationality can be enhanced by effective managerial incentives. For low- Q firms (Tobin's Q < 1 ), it is found that the concern of managerial self-interest overwhelms the benefits of internalization, making multinationality a value-decreasing event. For low- Q firms, managerial compensation is also ineffective in promoting value-enhancing foreign direct investments.  相似文献

As agricultural products move from being economic commodities to quality–differentiated goods, price dispersion within specific markets increases and implicit subsidies from high quality producers to low quality producers are removed. The present paper examines how these distributional effects can influence patterns of support and opposition to changes in marketing arrangements. The simple model developed is calibrated using data from the USA slaughter cattle market. Estimates of the impact on prices of measuring quality more accurately are found to be similar in size to previous estimates of market power price suppression in the market.  相似文献

The evolution of society and economic pressure has provided the impetus for operating on a 24-hr basis in many industries. This has occurred with relatively little attention toward sleep deprivation and related problems facing shift workers and the organizations employing them. This paper first documents the move toward shift work and some sleep problems associated with it. We then describe sleep disorders that impact job performance. Next, we describe alternative schedules and give suggestions for shift work implementation. Finally, we offer some normative advice regarding the treatment of shift employees.  相似文献

At some stage in every household's family life cycle, the household is likely to make certain decisions with regard to its housing environment. Although the household's housing decisions essentially comprise the decision to move, and the selection of a new residence, the process from which these decisions are derived is very complex because varying circumstances could produce a multitude of different housing decisions. Due to the sheer complexity of the household's housing decision–making process, researchers have generally focused on individual decision–making stages rather than on the process as a whole. This paper therefore attempts to conceptualize the entire household housing decision–making process using theoretical concepts from the economic perspective, and then tests the conceptual model with empirical evidence drawn from the moving population within the multi–racial society in Singapore.  相似文献
