Asymptotics for Autocovariances and Integrated Periodograms for Linear Processes Observed at Lower Frequencies

One of the most frequently used class of processes in time series analysis is the one of linear processes. For many statistical quantities, among them sample autocovariances and sample autocorrelations, central limit theorems are available in the literature. We investigate classical linear processes under a nonstandard observation pattern; namely, we assume that we are only able to observe the linear process at a lower frequency. It is shown that such observation pattern destroys the linear structure of the observations and leads to substantially different asymptotic results for standard statistical quantities. Central limit theorems are given for sample autocovariances and sample autocorrelations as well as more general integrated periodograms and ratio statistics. Moreover, for specific autoregressive processes, the possibilities to estimate the parameters of the underlying autoregression from lower frequency observations are addressed. Finally, we suggest for autoregressions of order 2 a valid bootstrap procedure. A small simulation study demonstrates the performance of the bootstrap proposal for finite sample size.     

RESPONSIBILITY AND CAPABILITY

This paper explores the issue of responsibility and links it to the concept of capability. The paper begins by looking at what it means to be responsible and connects this to the now common distinction in public policy between blame and task. It is argued that responsibility should be internalised rather than externalised and placed in the hands of the state. This can be done through the extension of property rights and so the paper offers a brief justification for the link between responsibility and property rights. The final part of the paper considers the ideas of capability and competence and uses these to argue for the placing of personal responsibility at the heart of public policy.     

LACK OF RIGOUR IN DEFENDING FAIRTRADE: A REJOINDER TO ALISTAIR SMITH

Smith (2010 ) does not deny that he made errors in economic theory, logic and fact, and that he had misused evidence. He says that I misrepresented a large body of theory, that I distorted what he said in four places and that I was wrong in one sentence. These statements are false.     

The Value of Changes in Deer Season Length: An Application of the Nested Multinomial Logit Model

Increasing deer populations can be controlled through manipulatingharvest limits or season length. While such actions often result in benefitsto hunters, both motorists and the agricultural sector also benefit as alower deer population leads to fewer incidences of harmful human-deerencounters. Traditional recreation demand models are often employed toexamine the welfare implications of changes in daily hunting bag limits.Studies measuring the effects of changes in season length, however, arenoticeably absent from the literature. This study uses a nested randomutility model to examine hunter choice over site and season selection toderive the values of changes in season length.     

The Growth of Jobless Households in Australia

In this article it is shown that individual-based measures of joblessness and household measures of joblessness have diverged over the last twenty years with joblessness becoming increasingly concentrated in certain households.     

Perceived risk and consumer decision making related to health services: a comparative study

It is acknowledged[Weinstein, N. and Nicolich, M. (1993) ‘Correct and Incorrect Interpretations of Correlation Between Risk Perceptions and Risk Behaviours’, Health Psychology, Vol. 12, No. 3, pp. 235–45.] that with the development of services marketing specifically related to health services comes a need to understand the aspects of consumer risk behaviour. This paper examines differences in perceived risk between health services, general services and goods and will seek to substantiate and develop a previous US study,[Murray, K. B. and Schlacter, J. L. (1990) ‘The Impact of Services Versus Goods on Consumer's Assessment of Perceived Risk and Variability’, Journal of the Academy of Marketing Science, Vol. 18, No. 1, pp. 51–65.] utilising a quantitative methodology with repeated measures and nested factors. The conclusions support the hypotheses that there are significant differences in perceptions of social and psychological risks when purchasing health services.
