MIDZUNO'S sampling procedure is considered where the first (n – 1) draws are carried out with simple random sampling without replacement and the nth draw with varying probabilities. It is shown that for this scheme, the best estimator in the HORVITZ–THOMPSON (1952) Tt–class of linear estimators exists and rejects the last draw. When MURTHY'S technique of unordering of an ordered estimator is employed, the rejected draw is restored and the unordered estimator is obtained. Surprisingly, this unordered estimator is the same as the unordered best estimator in the T1–class, derived for IKEDA–SEN'S sampling procedure. 相似文献

This paper examines the approach taken by Jamaica to control money laundering, terrorist financing and market abuse. With respect to money laundering and terrorist financing, the discussion involves a review of the statutory offences, the confiscation/forfeiture regime and the reporting obligations imposed on the financial sector. The analysis of market abuse focuses on both insider dealing and market manipulation. 相似文献

Understanding the economic integration of minority ethnic communities requires an analysis of the educational process. This paper examines second‐generation immigrant youths’ educational attainments in comparison with those of similarly aged native Swedes. Binomial‐logit, grouped‐regression and multinomial‐logit models are applied to longitudinal data, 1991–1996. The results give evidence for socioeconomic determinants of post‐compulsory education and for parental influence on educational choices. Parental income affects second‐generation immigrants’ post‐compulsory education and Swedes’ choice of level of education. In general, the stronger the labour market positions of the parents, the higher the probability of the children continuing education. It is also found that the geographical origin of second‐generation immigrants matter, with youths of Asian origin having a higher probability of continuing their education. We suggest policy changes on different levels based on the evidence of the paper, as short‐run, long‐run and in general. 相似文献

What is the impact of monetary policy on the Malaysian consumer? The study addresses this issue by empirically investigating the consequences of interest rate shocks on consumer credit in Malaysia. The study relies on the impulse response functions and the variance decomposition analysis based on the structural Vector Auto‐regression methodology. Apart from analysing the responses of aggregate consumer loans (ACL) to interest rate changes, further disaggregation is made in efforts to arrive at more detailed findings. In particular, the ACL data are categorized into loans for purchase of residential property, loans for personal uses, loans for credit cards, loans for purchase of consumer durables, loans for purchase of passenger cars and loans for purchase of securities. Through this disaggregation, the study shows the relative sensitivity of the various types of consumer loans to interest rate shocks. 相似文献

Quantifying the socio-economic determinants of sustainable crop production: an application to wheat cultivation in the Tarai of Nepal 总被引:1,自引:0,他引:1

This study specifies a procedure to quantify the determinants of sustainable crop production, and applies the method to wheat cultivation in the Tarai of Nepal. Three aspects of sustainability were considered. First, the fertility of the land was found to have deteriorated owing to long-term practices incompatible with soil and drainage conditions. Three-quarters of the farmers had reduced land fertility and for one-third of them the wheat yield was at least 20% lower than for farmers who applied farmyard manure to every crop and adopted a rotation consistent with soil and drainage conditions. Secondly, the study found that it was possible to improve resource-use efficiency in wheat production to give 25% higher production at current levels, type, and quality of farm resources. Resource-use efficiency was significantly related to farm management practices such as crop stand, variety, disease, and land preparation quality, and socio-economic factors such as off-farm job opportunities, poor plot accessibility, and migration. Thirdly, the increasing population pressure on land, decreasing livestock number per cropped area, and diminishing fuel wood sources, significantly reduced farm-based nutrient cycling because farmyard manure had to be used for fuel. This had implications for the higher use of the fossil-based inputs in crop production. 相似文献

This paper investigates the return and volatility response of major European and US equity indices to monetary policy surprises by utilizing extensive intraday data on 5-min price quotes along with a comprehensive dataset on monetary policy decisions and macroeconomic news announcements. The results indicate that the monetary policy decisions generally exert immediate and significant influence on stock index returns and volatilities in both European and the US markets. The findings also show that press conferences held by the European Central Bank (ECB) that follow monetary policy decisions on the same day have a clear impact on European index return volatilities. This implies that they convey additional important information to market participants. Overall, our analysis suggests that the use of high frequency data is critical to separate the effect of monetary policy actions from those of macroeconomic news announcements on stock index returns and volatilities. 相似文献

We examine the performance of several types of the consumption-based CAPM (C-CAPM) models to explore if consumption factors matter for determining excess returns across 17 MSCI country indexes. While the classic world C-CAPM does exhibit some power in explaining cross-sectional variations of expected excess returns, the model seems to require an implausibly large coefficient of risk aversion. The more sophisticated models including the heterogeneous C-CAPM, the world surplus consumption and the habit-formation models provide more reasonable estimates and add substantial explanatory power for the variation in the cross section of excess stock returns. Our results suggest that country-specific consumption risk is not fully diversified thus implying that stock returns are related to idiosyncratic consumption risk. 相似文献
