Men, Women and the Hiring Function

This paper examines the idea of ranking of groups and genders of unemployed labour force participants in terms of their hiring probabilities.We find a clear ranking of men over women in the hiring process in Australia. We also find that amongst males, employed job seekers are ranked above those unemployed and, in turn, above those not in the labour force. For women, the unemployed and employed are not found to be competing with each other, whilst those not in the labour force are ranked below the unemployed.     

Nationality,social network and psychological well-being: expatriates in China

Expatriate social networks constitute an under-emphasized area in expatriate literature. The current study contributes to the expatriate adjustment literature by empirically testing the relationship between expatriate personal networks and psychological well-being. The current study also investigates the hypothesis that expatriates from different cultural backgrounds will establish different social networks and adjust differently in China. A survey of 166 expatriates in China from North America, Europe and other countries in Asia showed significant support for the hypothesis that expatriate network characteristics have a direct and significant influence on expatriate psychological well-being. In addition, as predicted, expatriates in China from different cultural backgrounds (Overseas Chinese, other Asian, North American and European) established personal networks with different characteristics.     

Interdependence and the location of economic activities

This paper deals with the ability of a decentralized price system to sustain an optimal assignment of activities assuming complete interdependence among them. There are two goods, each of which is used in its own production and in the production of the other, along with land. An infinitely elastic final demand exists for both goods at given market prices, and either good may be imported. It is demonstrated that a decentralized price system will sustain an optimal allocation of land, and that a nonoptimal allocation of land will not be sustained.     

Subsampling the distribution of diverging statistics with applications to finance

In this paper we propose a subsampling estimator for the distribution of statistics diverging at either known or unknown rates when the underlying time series is strictly stationary and strong mixing. Based on our results we provide a detailed discussion of how to estimate extreme order statistics with dependent data and present two applications to assessing financial market risk. Our method performs well in estimating Value at Risk and provides a superior alternative to Hill's estimator in operationalizing Safety First portfolio selection.     

Stability of international stock market relationships across month of the year and different holding intervals

Potential benefits from international diversification depend upon the stability in stock market relationships. Using monthly data of 11 international stock markets, this paper examines the stability in stock market relationships across month of the year and across different holding intervals. Empirical results show that the correlation structure is more stable than the covariance structure. While empirical evidence supports the hypothesis that the correlation structure is very stable across different holding intervals, the empirical support for the stability in correlation structure across month of the year is much weaker.     

Bank Consolidations and Minority Neighborhoods

This paper explores the relationship between neighborhood racial composition and the level of banking services. We use unique census tract-level data on banking services and neighborhood characteristics in Alameda County, California, from points in time before and after the recent wave of bank consolidations to eliminate as well as possible the potential for omitted variables bias that could plague cross-sectional study of the issue. Using a variety of specifications and numerous sensitivity checks, we find that minority neighborhoods (particularly black neighborhoods) are less likely to have banking services, and are more likely to lose services during bank consolidations.     

Aggregation of Directional Distance Functions and Industrial Efficiency

Three main objectives are pursued in this paper. First, we intend to analyze the aggregation problem of directional distance functions from a constructive viewpoint. We provide necessary and sufficient conditions concerning the structural properties of the production technology and of the nature of groups of firms. Indeed, exact additive aggregation holds for a linear technology and for a direction solely defined in the output space. Second, since these conditions are somewhat restrictive, we are interested in providing a measure for the aggregation bias through the relationship between industrial and structural technical efficiency. Finally, we show that this aggregation bias is a lower bound for industrial allocative efficiency.
