Using a sample of Australian Multi-sector trusts we examine selectivity and market timing performance and extend the analysis to include the relatively new measure of volatility timing. This is of particular relevance to our data set, as high levels of volatility persistence are prevalent in Australia. In addition we consider the stability, asymmetry and seasonality of the various performance and risk measures. A survivorship adjustment procedure is also employed in order to assess the impact of survivorship on selectivity, market timing and volatility timing performance. 相似文献

In the presence of foreign factor ownership tariffs change not only the terms of (goods) trade but also income flows between countries. Assume that only the home country owns factors abroad. Then the optimal tariff is negative if and only if foreign factor ownership entails trade-pattern reversals. Trade-pattern reversals are neither a necessary nor a sufficient condition for a negative optimal tariff if the foreign country owns factors in the home country. Changes in the home country's tariff shift the foreign country's offer curve. This adds a new dimension to optimal tariff analysis. 相似文献

Summary In most traditional macroeconomic models for The Netherlands the wage equation is specified by a Phillips curve, in which wage growth is negatively related to the unemployment rate. This paper shows, however, that wage formation can better be described by the so-called wage curve, in which the wage level, instead of wage growth, depends negatively on the unemployment rate.The author thanks S.K. Kuipers and D.A.G. Draper and other colleagues of the Central Planning Bureau for their useful comments. 相似文献

This paper presents the basic analytics of a debt/equity swap and illustrates the concept with a detailed example of American Express Bank's swap transactions that began in 1986 and have resulted in construction of seven hotels in Mexico during the course of the swap agreement. The economics of the swap are presented from the lending bank's view, from the foreign direct investor's view, and from the borrowing country's view. It is concluded that: swaps offer net benefits to the borrower country when additional investment is generated (from the swap transaction itself and/or from encouraging further investment as a result of the swap policy); they offer net benefits to the lender when future loan servicing prospects are poor and viable investment opportunities exist; and they offer net benefits to the direct investor when the cost of financing the investment through the swap is less than for alternative financing sources.
The analytical framework presented here allows the bank lender to formally compare alternatives of holding impaired LDC loans on its books, selling the loans in the secondary market, trading the loans for loans from another country, and swapping the loans for equity investments in the borrowing country. It similarly allows the government policymaker to compare the relevant economic costs and benefits of swaps, so that better swap policies can be developed. 相似文献

The influence of lagged adjustment and consumer spending on retail labour productivity is investigated. Both influences result in a procyclical productivity pattern. 相似文献

The paper asks the question – as time series analysis moves from consideration of conditional mean values and variances to unconditional distributions, do some of the familiar concepts devised for the first two moments continue to be helpful in the more general area? Most seem to generalize fairly easy, such as the concepts of breaks, seasonality, trends and regime switching. Forecasting is more difficult, as forecasts become distributions, as do forecast errors. Persistence can be defined and also common factors by using the idea of a copula. Aggregation is more difficult but causality and controllability can be defined. The study of the time series of quantiles becomes more relevant. 相似文献
