考后放松游市场特征分析及开发探讨

近年来，伴随旅游业的蓬勃发展，考后放松游逐渐兴起并日益升温。潜力巨大，收益率颇高。研究发现：考后放松游出游时间长且相对集中；考后放松游游客消费能力较强；出游形式多样，港澳地区成为考后放松游游客最理想的旅游目的地；考后放松游游客对滨海旅游线路和名校参观体验游表现出明显的偏好。针对考后放松游以上特点，进行定量分析。得出考后放松游市场人均消费总额的构成因素，旨在揭示其规律，为今后相关研究打下基础并提供依据。     

The Impact of Agricultural Import Tariff on Economic Growth： Evidence From Mercosur Countries

This research paper attempts to determine the relationship between agricultural import tariff and economic growth of Mercosur countries over the period 1996-2007 using regression analysis as well as evaluates the gains and losses from the group＇s trade policy over the same period. The introductory part of this paper focuses on the dynamics of changes in economic growth, trade, and import tariff of these countries over the last two decades. The results of the performed regression analysis of panel data suggest that trade liberalization has a quantitatively significant positive effect on growth. By using the coefficient estimates on tariff, the authors perform a quantitative evaluation of gains and losses from trade policy, for which tariff measures to trade （imports） are used as a proxy.

Precautionary saving under liquidity constraints: Evidence from rural Pakistan

This paper investigates precautionary saving under liquidity constraints in Pakistan using household panel data. In particular, while it estimates Kimball's [Kimball, M.S. Precautionary saving in the small and in the large. Econometrica 1990; 58; 53–73.] prudence parameter based on a framework that is similar to Dynan [Dynan, K.E. How prudent are consumers? Journal of Political Economy 1993; 101; 1104–1113.], this study deviates from the framework by explicitly considering liquidity constraints, as in Zeldes [Zeldes, S.P. Consumption and liquidity constraints: an empirical investigation. Journal of Political Economy 1989; 97; 305–346.]. By doing so, this paper attempts to differentiate the standard precautionary saving caused by uncertainty from that caused by liquidity constraints. Furthermore, endogenous liquidity constraints are used in order to resolve issues of selection biases. We find substantial evidence of the presence of precautionary saving in Pakistan. More specifically, the estimated prudence is significantly higher for liquidity-constrained households as compared with unconstrained ones. The finding suggests that the precautionary saving motives appear stronger when households see that their access to credit markets is limited.     

DO PERCEPTIONS BECOME REALITY? THE MODERATING ROLE OF SUPPLY CHAIN RESILIENCY ON DISRUPTION OCCURRENCE

The concern and study of supply risk and supply continuity has recently come to the forefront in managing business and conducting research. This empirical study of U.S. and German firms investigates the relationship between perceived supply risk sources and supply disruption occurrence, as well as the use of supply chain resiliency practices to reduce disruption frequency. We demonstrate that supply managers' concerns with risk emanating from suppliers and the supply market are positively related to supply disruption occurrence. We further show how and when implementing flexibility and redundancy may reduce the effects of supply disruptions.     

网上商品热销的影响因素探析——基于分位数回归的实证研究

本研究从网上销售的影响因素出发,采用搜索程序获取了淘宝网的4059个货架1周的销售数据,通过分位数回归方法对不同热门程度产品的价格、信誉、保障标记以及口碑的需求弹性进行了实证分析。研究结果表明,随着产品热门程度的提高,信誉的需求弹性不断增强,而价格、保障标记以及口碑的需求弹性却不断减弱。由此表明,产品的价格降低,保障标记级别和口碑的提升都能使销售趋于分散,而提高商家的信誉却能加速销售向热门产品集中,使得"热门更热"。     

A trivariate model of participation,fertility and wages: the Italian case

Italy has unusually low fertility by OECD standards, accompaniedby unusually low female participation in paid work. This paperaddresses the issue of the empirical relationship between fertility,female participation in the labour market and wages with theseItalian 'peculiarities' as a backcloth. A trivariate model ofparticipation, fertility and wages has been constructed andestimated using three pooled cross-sections of Italian microdata, allowing for the identification of cohort effects. Thismodel follows a 'purist' approach: the participation and fertilitydecisions, as well as the wage equation, are modelled as completelyjoint. The cohort effects turn out to be significant: the pointestimates do not appear to confirm actual trends, which arenegative for fertility and positive for participation. The femalewage is the most important variable influencing the propensityto have children and the propensity to participate in the labourmarket, casting doubt on suggestions that observed trends arethe products of shifts in women's 'tastes'.     

Determinants of demand for international tourist flows to Turkey

This article describes the development and findings of a set of models used to identify the most important of the following selected variables influencing international tourist flows to Turkey: per capita income; relative prices; relative exchange rate; promotional expenditure (the Turkish Government has invested a substantial amount in promoting foreign tourism) and ‘special events’, eg political unrest. The demand for travel was measured both by the number of tourists, and by the total tourist expenditure. Data were obtained from secondary sources, and analysis was by least squares multiple regression. Income, price and exchange rate were found to be important factors but the impact of promotional expenditure was minimal     

A uniform weak law of large numbers under π-mixing with application to nonlinear least squares estimation

Abstract  In B ierens (1981) we have derived a uniform weak law of large numbers for stochastically stable processes with respect to a finite-dependent base. In this paper we show that this uniform weak law carries over to stochastically stable processes with respect to a, more general, φ-mixing base. This generalization will be used for relaxing the conditions for weak consistency and asymptotic normality of nonlinear least squares estimators.
