AUSTRALIAN IMMIGRATION ARCHIVES AS SOURCES FOR BUSINESS AND ECONOMIC HISTORY

The administration and control of immigration to Australian during the twentieth century produced a huge archive of records of individual migrants that have potential for innovative approaches to the business and economic history of ethnic minority groups. This article describes some of these records, which have mostly been used by amateur family historians, focused on those related to Chinese immigrants before the World War II and Southern Europeans immigrants after 1945. The article gives examples of how these records can be used, suggests potential research projects, and discusses briefly some of the guides available. Several images of these archival documents are reproduced.     

A quantitative model for the evaluation of technological alternatives

This paper presents a quantitative model that may be of use to the national development planners, investment funding authorities, and entrepreneurs, who are confronted with the problems of choosing the appropriate technology among many available alternatives. The model provides a systematic and analyst-independent methodology for the multicriterion technology selection process, which requires consideration of socioeconomic as well as technological factors. The procedure is mathematically straightforward and has the capability of integrating both objective and subjective aspects of the evaluation process, resulting in a unified technology measure as a guide for decision making. A case study is presented to illustrate the applicability and workability of the development model.     

DURABLE GOODS MONOPOLISTS AND BACKWARD COMPATIBILITY*

This paper provides an economic analysis on the choice of backward compatibility by a durable goods monopolist in the presence of network effects. We examine the time inconsistency problem faced by a monopolist in its dynamic provision of two compatible products. We suggest an economic reason why, and when it will be strategically optimal, for the monopolist to choose backward compatibility even though it is socially undesirable, and not to choose forward compatibility even though it is technologically possible. We also investigate the compatibility choices with and without price discrimination, and compare market outcomes with the social optimum. Two different social inefficiencies (planned obsolescence) which arise from the viewpoints of optimal consumption and optimal compatibility are discussed.     

Cost frontier efficiency and risk-return analysis in an emerging market

The paper investigated cost efficiencies and its relationship with risk-return behavior of banks in United Arab Emirates (U.A.E.). The major findings are that there were 10-25% inefficiencies in these banks under different cost specifications. On the risk-return front, lower liquidity and lower capitalization risks coupled with higher ROE significantly improved the cost efficiencies of the banks. Further, domestic banks were relatively cost efficient than foreign banks. These findings are useful to emerging market participants in their investment decisions, as also the policymakers and bank regulators to monitor inefficient banks in the context of revised Basel capital norms.

本文采用实证研究方法,对我国可转换债券的时机选择问题进行了研究。研究结果表明:a.我国企业发行可转换债券,偏好权益市场收益率较高的月度;b.企业发行可转换债券的时机选择与企业长期债券收益率(或成本)的变化之间不存在必然的联系;c.企业发行可转换债券时,普遍不存在严重的代理冲突问题。     

Identification and estimation of statistical functionals using incomplete data

Incomplete data, due to missing observations or interval measurement of variables, usually cause parameters of interest in applications to be unidentified except under untestable and often controversial assumptions. However, it is often possible to identify sharp bounds on parameters without making untestable assumptions about the process through which data become incomplete. The bounds contain all logically possible values of the parameters and can be estimated consistently by replacing the population distribution of the data with the empirical distribution. This is straightforward in some circumstances but computationally burdensome in others. This paper describes the general problem and presents an empirical illustration.     

Análisis del servicio de Urgencias aplicando teoría de líneas de espera

Those responsible for making decisions in hospitals are increasingly aware of the need to efficiently manage hospital systems. An option for analysis is done by queuing models. In this paper is analyzed the service area ER, in a public hospital applying the concepts and relationships of waiting lines. From the model results, it is concluded that in the emergency department does not have the required minimum number of doctors to allow a steady flow of patients. With the model, the minimum required number of doctors is calculated to meet current and future demand for service with the same service time and the same discipline of service. Analytical models, allowing direct understand the relationships between service demand, number of doctors and patient care priority viewed as a queuing system. The work is useful for administrators and managers of hospital systems.     

A unifying approach to risk-measure-based optimal reinsurance problems with practical constraints

The design of optimal reinsurance treaties in the presence of multifarious practical constraints is a substantive but underdeveloped topic in modern risk management. To examine the influence of these constraints on the contract design systematically, this article formulates a generic constrained reinsurance problem where the objective and constraint functions take the form of Lebesgue integrals whose integrands involve the unit-valued derivative of the ceded loss function to be chosen. Such a formulation provides a unifying framework to tackle a wide body of existing and novel distortion-risk-measure-based optimal reinsurance problems with constraints that reflect diverse practical considerations. Prominent examples include insurers’ budgetary, regulatory and reinsurers’ participation constraints. An elementary and intuitive solution scheme based on an extension of the cost–benefit technique in Cheung and Lo [Cheung, K.C. & Lo, A. (2015, in press). Characterizations of optimal reinsurance treaties: a cost–benefit approach Scandinavian Actuarial Journal. doi:10.1080/03461238.2015.1054303.] is proposed and illuminated by analytically identifying the optimal risk-sharing schemes in several concrete optimal reinsurance models of practical interest. Particular emphasis is placed on the economic implications of the above constraints in terms of stimulating or curtailing the demand for reinsurance, and how these constraints serve to reconcile the possibly conflicting objectives of different parties.
