林权改革推进中农户林业合作经营的动因

集体林权制度改革后,小农户与大市场之间的矛盾,是我国林业发展的一个突出矛盾。要解决这一矛盾,提升农户进入市场的能力,需提高分散农户在林业经营中的合作程度。从内外两方面探究了农户林业合作经营需求产生的动因,认为合作需求的产生受农户自身内在驱动因素与外部环境推动因素的共同作用,政府在制定相关扶持政策时应以农户需求为基础,尊重农户意愿。     

消费者对可追溯牛肉的认知及其影响因素分析——基于结构方程模型

利用针对北京市城区消费者的402份调查问卷数据,运用结构方程模型,分析了消费者对可追溯牛肉的认知及其影响因素。结果显示,消费者对可追溯牛肉的认知水平较低,但消费者在信息强化后对可追溯牛肉安全性的评价较高;信息搜集和经济文化因素显著影响消费者对可追溯牛肉的认知水平,风险感知、牛肉重要性和经济文化因素显著影响消费者对可追溯牛肉的认知内容,但认知水平并不显著影响认知内容。最后提出相关对策建议。

Expenditure elasticities of the demand for leisure services

Although some research has already focused on the analysis of expenditure elasticities of leisure demand, some shortcomings with regard to the content and the underlying theoretical model as well as the applied methods exist. This article aims at avoiding these problems to provide consistent derivatives of leisure service expenditure elasticities. Therefore, a regular demand system is derived from microeconomic duality theory. To implement leisure specific demand factors (i.e. demand- and supply-based sports and recreational opportunities as well as sports and recreational preferences) while still being consistent with neoclassical demand theory, the basic model is extended by applying the demographic translation framework. Data of the continuous household budget survey (n?=?7724) from Germany is used for the estimation of the derived demand system. It is shown how sensitive the results are depending on the applied (censored) regression model: 16 out of 18 analysed services are indicated as luxury goods based on the findings of the Tobit model type I but as necessities based on the findings of the Tobit model type II. Possible implications are presented and discussed.     

Abstraction and product categories as explanatory variables for food consumption

This study sets out to explore variation in the consumer choice structure in relation to three types of products with different levels of search, experience and credence attributes. The decision structures of rice, wine and functional food (experience, search and credence products) consumers were explored by means of laddering. The results suggest the presence of an emotional component in foods that increases in complexity (becomes more abstract) with the number of credence attributes. The findings recommend adjusting the complexity of advertising campaigns and product positioning to the type of product being promoted.     

Identifying significant characteristics of organic milk consumers: a CART analysis of an artefactual field experiment

The organic dairy category is one of the fastest growing categories of organic foods in the US. Organic milk consumers generally cite perceived health benefits and lower risk of food contamination, as well as perceived superior quality and environmental sustainability of organic farming methods, as the major motivations for preference of organic over conventional milk. While the attributes of organic milk that are valued by consumers are fairly well-known, more ambiguity exists regarding the demographic characteristics of the typical organic milk consumer. This research makes use of experimental data from 148 adult participants and use a Classification and Regression Tree (CART) analysis, a nonparametric modelling approach, to identify how Willingness-to-Pay (WTP) for organic milk varies with the demographic profile of experiment participants. The study finds that perceived taste of organic milk, concern for the risk of consuming conventional milk, being a primary shopper, and the quantity of milk consumed are the major factors that separate experiment participants into groups with high and low WTP for organic milk.     

The effects of oil price shocks on expenditure category CPI

In this study, we apply a two-block structural vector autoregressive (VAR) model proposed by Kilian and Park (2009) in order to investigate the dynamic effects of changes in oil price on the expenditure category consumer price index (CPI) in the United States and Japan. Our results confirm that each expenditure category price index responded very differently to the same structural shock, and that whether changes in oil price function as a positive stimulus or a negative shock for the individual expenditure category prices also depends on the kind of underlying shock that drives the changes in oil price. Finally, our results also reveal that the manner in which changes in oil price affect each expenditure category price differs between the United States and Japan and these detailed-level differences may lead to aggregate-level differences in the price response of both countries to changes in oil price.     

Happiness of economists

We study the importance of economists’ professional situation towards their life satisfaction based on a unique survey of mostly academic economists. On average, economists report to be highly happy with life. Satisfaction is positively related to spending more time on doing research. The lack of a tenured position decreases satisfaction. However, the extent to which the uncertainty created by the tenure system affects satisfaction varies with the contract terms. The effect is stronger if the contract expires in the near future or cannot be extended. Publication success has no effect if it is controlled for academic rank and the contract duration. The finding suggests that publications are rather a means to an end, for example, to acquire a tenured position. While the perceived level of external pressure also has no impact, the perceived change of pressure in recent years is positively related to economists’ life satisfaction. An explanation is that economists have accepted a high level of pressure when entering academia but are not willing to cope with the recent increase.     

Financial market and housing wealth effects on consumption: a permanent income approach

The objective of this study is to examine the financial market and housing wealth effects on consumption. Housing has the dual functions as both a commodity yielding a flow of housing services and an investment asset yielding a flow of capital income. With the construction of an empirical framework based on the vector autoregression approach, the findings from this study suggest that a rise in housing price has both a positive wealth effect and a negative price effect on consumption. While the positive wealth effect is caused by an increase in capital income, the negative price effect is caused by an increase in the cost of housing services. In addition, the housing market wealth effect increases, at the expense of the price effect, with the level of housing-market leverage. These findings imply that the government policy of land supply aiming to stimulate the economy should strike a balance between the possible wealth and price effects of the housing market.     

Monetary dynamics: a market approach

The behaviour of the short-run responses implied by the identification of a long-run money demand relationship is examined. These responses have recently been interpreted as representing the policy stance of the monetary authority. However, as movements in the monetary aggregate reflect both demand and supply adjustments, estimating the short-run dynamics solely within the money demand relationship may produce biased results. In order to address this issue, the paper explicitly acknowledges the importance of the supply of money function by including the function alongside the demand for money function. While the interaction of the two equations continues to produce the long-run quantity theory result, the additional detail provides more accurate estimates of the individual short-run adjustments within the two equations.
