农民对宅基地权利认知及影响因素研究*——以河北省新乐市为例

［目的］通过对河北省新乐市农民在宅基地权力认知及影响因素方面的分析，探究我国农村宅基地制度并提出相关建议。［方法］文章受制度功能可信度理论启发，以河北省新乐市14个行政村为调研对象，探究农民对宅基地相关权利认知情况，同时采用Spearman相关性分析研究影响农民宅基地认知的因素。［结果］调研地自发宅基地流转市场已形成，宅基地制度功能处于社会保障功能向财产功能转变的过渡阶段； 农民对宅基地所有权认知不明晰，但并不影响宅基地市场建立； 在宅基地流转中，农民更关注相互之间信任、村委会保留的记录、流转中形成的“事实产权”； 农民性别、年龄、受教育水平和家庭人口数是影响权利认知的主要因素。［结论］依据制度功能可信度理论充分考虑宅基地制度在现阶段的功能变化，因地制宜； 政府应关注农民的宅基地使用权问题，使其真正成为农民的财产； 应对农村宅基地流转中形成的事实产权逐渐正式化； 应制定年轻人就业帮扶和年长者社会保障等相关政策，避免宅基地流转影响农村社会稳定性。     

Minimum Pay Scale and Career Length in the NBA

We use data from the National Basketball Association (NBA) to analyze the impact of minimum salaries on an employee's career length. The NBA has a salary structure in which the minimum salary a player can receive increases with the player's years of experience. The NFL has a similar minimum wage policy; research suggests that the introduction of this system shortened career length in the NFL. Using duration analysis, we fail to find evidence that the new multi‐tiered minimum wage scale in the NBA increased the probability of exit.     

Sustainability in the Transport and Logistics Sector: Lacking Environmental Measures

Sustainability as part of the development of companies' business strategies is gaining in importance. Due to its impact on the environment, this is particularly essential for companies of the transport and logistics sector. This paper explores several factors that influence the environmental behaviour of transport and logistics companies in Austria. It discusses the importance of the economic impact on environmental management decision in detail and analyses the sector's specific characteristics in terms of environmental behavior. A case‐based approach involving multiple field studies with face‐to‐face expert interviews and secondary data analysis was used to evaluate environmental performance and specific practices. Using selected cases, we will demonstrate how environmental measures contribute to overall business performance and draw general conclusions regarding the transport and logistics sector. Furthermore, suggestions are given as to how the government can further support transport and logistics companies in this regard. Copyright © 2013 John Wiley & Sons, Ltd and ERP Environment.     

STRATEGIC ASSET ALLOCATION FOR LONG‐TERM INVESTORS: PARAMETER UNCERTAINTY AND PRIOR INFORMATION

We study the effect of parameter uncertainty on the long‐run risk for three asset classes: stocks, bills and bonds. Using a Bayesian vector autoregression with an uninformative prior we find that parameter uncertainty raises the annualized long‐run volatilities of all three asset classes proportionally with the same factor relative to volatilities that are conditional on maximum likelihood parameter estimates. As a result, the horizon effect in optimal asset allocations is much weaker compared to models in which only equity returns are subject to parameter uncertainty. Results are sensitive to alternative informative priors, but generally the term structure of risk for stocks and bonds is relatively flat for investment horizons up to 15 years.

Consumer responses to different degrees of advertising adaptation: the moderating role of national openness to foreign markets

We investigate the moderating role of national openness to foreign markets on consumer responses (attitude to ad, brand and purchase intention) to different degrees of advertising adaptation in Belgium, Iran and India. We operationalize three levels of advertising adaptation (standardization, glocalization and adaptation) by manipulating the model (international versus local celebrity) and advertising copy (international versus local advertising copy). The results show that societies with a low openness to foreign markets respond more positively to fully adapted ads than to glocalized and standardized ads. The differences in responses decrease with national openness.     

Kfz-Steuer für Pkw: Hubraum lässt sich doch ersetzen!

In Germany the car tax is derived from the cylinder capacity. Since 2009 the amount of carbon emissions serves as an additional criterion. Taking recent developments into account, cylinder capacity can no longer be justified as a reasonable tax basis. Instead I propose a progressive tax based solely on carbon emissions to achieve much more appropriate results.     

Hartz IV: die Lösung für die Probleme in der Währungsunion?

The Hartz reforms are often regarded as the therapy which turned the so called “sick man of Europe” into a global superstar. But this diagnosis was wrong. The strength of the German economy was overshadowed by the negative effects of reunification. The decline in unemployment can partly be attributed to the end of the transformation in East Germany. It also reflects the negative cyclical situation in 2005. This analysis is in line with the finding that compared e.g. with Italy and Greece, German unemployment assistance is still very generous. Thus, for the member states of the Eurozone Hartz IV is not a promising strategy. This could be different should wage moderation be cosnidered. However, if member states practice it simultaneously, this will lead to deflation. This calls for higher wage increases in Germany and a more symmetric adjustment.     

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.     

Limit theorems for reflected Ornstein–Uhlenbeck processes

This paper studies one‐dimensional Ornstein–Uhlenbeck (OU) processes, with the distinguishing feature that they are reflected on a single boundary (put at level 0) or two boundaries (put at levels 0 and d > 0). In the literature, they are referred to as reflected OU (ROU) and doubly reflected OU (DROU), respectively. For both cases, we explicitly determine the decay rates of the (transient) probability to reach a given extreme level. The methodology relies on sample‐path large deviations, so that we also identify the associated most likely paths. For DROU, we also consider the ‘idleness process’ L_t and the ‘loss process’ U_t, which are the minimal non‐decreasing processes, which make the OU process remain ≥ 0 and ≤ d, respectively. We derive central limit theorems (CLTs) for U_t and L_t, using techniques from stochastic integration and the martingale CLT.
