This pa per suggests a simple valuation method based on Chebyshev approximation at Chebyshev nodes to value American put options. It is similar to the approach taken in Sullivan (2000), where the option`s continuation region function is estimated by using a Chebyshev polynomial. However, in...

This paper examines whether, in addition to standard unit root and cointegration tests,panel approaches also produce test statistics behaving erratically when applied to PPP. We show that if appropriate tests (which are robust to cross-sectional dependence and more powerful) are used, any...

In the absence of any official measures of old age poverty, this paper uses National Sample Survey household-level data to investigate the extent and nature of living standards and incidence of poverty among elderly in sixteen major states in India. We construct both individual and...

Monthly seasonally unadjusted data can exhibit roots with possibly fractional orders of integration, corresponding to the monthly but also to the quarterly and to the long-run or trending components of the series. In this paper we use a procedure which is suitable to test simultaneously for the...

This paper examines historical data on daily real wages in England for the time period 1260-1994 by means of new statistical techniques suitable for modelling long memory both at the long run and the cyclical frequencies. Specifically, it uses a procedure due to Robinson (1994) which is based,...

This paper argues that the adoption of an inflation target reduces the persistence of inflation.We develop the theoretical literature on inflation persistence by introducing a Taylor rule for monetary policy into a model of persistence and showing that inflation targets reduce inflation...

We model public-private partnershios in building and managing facilities for the provision of public services. In particular,we analyze both the desirability of bundling the building and management operations, and the optimal allocation of ownership between the public sector and private firms....

This paper examines a version of the tests of Robinson (1994) that enables one to test models of the form (1-Lk)dxt = ut, where k is an integer value, d may be any real number, and ut is I(0). The most common cases are those with k = 1 (unit or fractional roots) and k = 4 and 12 (seasonal unit...

The level of the IPO spread taken by the underwriter is a controversial issue.Some claim that the level is too high and attributes it to collusion between investment banks while others contend to the contrary. The paper examines the spread in the framework of conflicts of interests between the...

This paper develops a model for the forward and spot exchange rate which allows for the presence of a Markov switching risk premium in the forward market and considers the issue of testing for the unbiased forward exchange rate (UFER) hypothesis. Using US/UK data, it is shown that the UFER...
