Investment Guide to Tianjin

With11,919.7 square kilometers areas, Tianjin Municipality is located in the middle of the Golden Seashore in North China. To the north is Yan Mountain and to the east is Bo Sea. It borders Beijing and is the gateway to the sea of the vast northern and northwestern part of China. It has the semi humid continental monsoon climate of the Temperate Zone： 12 Degrees Centigrade of average temperature of the whole year, and 602.9 mm annual average precipitation.     

Revenue and operational impacts of depeaking at U.S. hub airports

Historically, peaked schedules have been used with hub-and-spoke networks to maximize passenger connection opportunities. Although peaked schedules can generate more attractive connecting itineraries and revenue for an airline, they are costly to operate because additional manpower and equipment resources are needed to serve the peak periods. Several airlines experimented with depeaking their hubs as a way to reduce costs and improve operations in the 2000s. Prior studies have quantified operational improvements and cost savings associated with depeaking; however, none have quantified revenue impacts. We use difference-in-differences methods to quantify revenue and operational impacts associated with depeaking for five U.S. hubs. Results show that depeaking tends to improve operations, but may negatively impact revenue per available seat mile (RASM). In some cases, revenue losses exceed reported cost savings.     

施工项目质量进度安全管理措施研究

保证项目施工质量、施工进度、施工安全和利润最大化是施工企业的管理目的。根据施工现场实际情况并结合施工项目特点,对施工项目质量、进度、安全管理措施及其应用进行了研究,尽量做到以预防为主,把工程质量、进度、安全控制从事后检查转向事前控制、事中控制,从对工程质量的检查转向对工作质量的检查,对工序质量的检查,对中间产品的质量检查;要求在保证质量和安全的前提下,尽量缩短工期,进而将成本控制在最低。

A Quantile Regression Analysis of the Effect of Farmers’ Attitudes and Perceptions on Market Participation

The objective of this study is to investigate the subjective determinants of farmers’ participation in output markets in five EU New Member States (NMS) characterised by large semi‐subsistence sectors. It employs quantile regression to model market participation reflecting the heterogeneity amongst farmers. The study also uses the Bayesian adaptive lasso to simultaneously select important covariates and estimate the corresponding quantile regression models. The empirical results show that only two variables affect all quantiles, while their effect varies across quantiles. Some of the remaining variables affect the share of output sold at the lower quantiles (i.e. for subsistence‐ and semi‐subsistence‐oriented farmers) only, whereas other variables are only significant at the upper quantiles (i.e. for more commercially oriented farms). Advisory services, and particularly agricultural business advice, and information and advice on markets and prices can facilitate the market participation of subsistence‐oriented farms.     

Parity reversion in the Asian real exchange rates: new evidence from the local-persistent model

This article investigates the time-series properties of 13 Asian real exchange rates (RERs) vis-à-vis the US dollar. The half-life point estimates drawn from the local-persistent model are all less than 2 years, with a finite upper bound. There is no evidence to indicate that the Asian financial crisis has altered the speed of the purchasing power parity (PPP) adjustments. We find that the persistence of RERs over the last three decades remains unchanged in majority of the cases. Given the fairly rapid speed of adjustments and their corresponding confidence intervals, we conclude that the PPP puzzle does not exist in these countries.

Out of Bounds: Do SPF Respondents Have Anchored Inflation Expectations?

Since the Federal Open Market Committee announced a 2% inflation target in 2012, the median long-run inflation forecast of professional forecasters has been near target. We show, however, that most individual forecasters' long-run inflation expectations fluctuate substantially, with sizeable departures from target. We propose a new “bounds anchoring” indicator based on deviations of individuals' long-run forecasts from target. This indicator sheds new light on gradual changes in expectations since the 2012 announcement. We find that bounds anchoring gradually strengthened in the years following the target announcement, but that this trend has recently started to reverse.
