实际有效汇率影响中国纺织品服装贸易的实证分析

纺织品服装是中国具有比较优势的大宗出口商品,在中国对外贸易中有重要的地位。文章运用最小二乘估计法,就人民币实际有效汇率对中国纺织品服装进出口贸易的影响进行了实证分析。结果表明,人民币实际有效汇率变动对中国纺织品服装进出口有显著影响,且其对进口的影响明显大于对出口的影响。另外,收入水平也是影响中国纺织品服装进出口的主要因素。     

新疆企业用工需求与劳动力供给问题调查研究

发展是第一要务,是解决新疆一切问题的基础。中央新疆工作座谈会的召开,19个省市的大力支持,以及中央出台的一系列特殊优惠政策和措施,为新疆大建设、大开放、大发展提供了前所未有的历史机遇。疆内众多企业在此大环境下抓住有利时机,增加订单,扩大产能,千方百计加快发展。此时企业用工需求量也在大幅增加,出现了“招工难”、“用工荒”的社会现象,已影响到企业的生产经营和发展前景。本文立足新疆实际,采用问卷调查的方法,对当前企业用工和劳动力供给状况以及存在的问题开展调查研究,深刻剖析了企业劳动力供给与需求不匹配的原因和症结,并提出政策建议。     

Is insurance normal or inferior? -A regret theoretical approach-

This study considers how changes in wealth affect insurance demand when individuals suffer disutility from regret. Anticipated regret stems from a comparison between the ex-post maximum and actual wealth. We consider a situation wherein individuals maximize their expected utility incorporating anticipated regret. The wealth effect on insurance demand can be classified into the risk and the regret effects. These effects are determined by the properties of the utility function and the regret function. We show that insurance can be normal when individuals place weight on anticipated regret, even though the utility function exhibit decreasing absolute risk aversion. This result indicates that regret theory is a possible explanation to the wealth effect puzzle, in which insurance is normal from empirical observation, but it should be inferior by theoretical prediction under expected utility theory.

Your Call: eBay and Demand for the iPhone 4☆

The iPhone 4 was introduced into the UK market on 24^th June 2010 to significant consumer interest. Demand revealed itself exceeding supply through conventional channels, since there was very extensive activity in terms of bidding on eBay auctions for the product. We monitored all UK eBay transactions on the iPhone 4 for six weeks from introduction, with total transactions amounting to around £1.5m. We analyse determinants of winning bids in terms of characteristics of the phone, the seller, and the buyer. Our most notable and novel finding relative to previous studies is a very significant premium over list price being paid in almost all cases, with positive uplift factors including whether the phone was unlocked and whether it could be sold overseas. Demand fell over time, as evidenced by lower achieved prices, but the fall in price was relatively modest. A significant premium of 32GB over 16GB versions is revealed.     

Critical mass of users versus critical mass of services in a multiproduct information service system

In this paper we study the economic behaviour of the suppliers of a set of advanced telecommunications services with a joint adoption cost (common access facilities, learning process, etc.). In fixing the two-part tariffs for their services the suppliers have to share the burden of leaving to the users a surplus sufficient to cover the adoption cost. The lack of coordination in supplying a critical mass of services or in the pricing decisions has high changes to result in suboptimal or unviable diffusion of the new technology as a whole. We present a static optimization model of user behaviour, and derive access and usage demand with a two-part tariff and a joint adoption cost. We compare noncooperative and cooperative market equilibria in a duopoly with perfect information; finally we discuss the extension of our analysis to the case of imperfect information in a dynamic setting.

Credit Conditions in Pakistan: Supply Constraints or Demand Deficiencies?

This paper attempts to pin down the key drivers of demand for and supply of real private sector credit in Pakistan. I use both the equilibrium and disequilibrium econometric frameworks, specifically tackling the issue of lack of consistency and/or efficiency of joint estimators in the former via the three‐stage least squares technique. On the demand side, I find that higher economic activity provides stimulus to credit whereas inflation dampens it. The stock market seems to play a dual role: as a source of alternative financing, a bullish market negatively impacts credit while, as an indicator of economic expectations, it provides a positive impetus. On the supply side, banks' lending capacity is found to be the major driver of credit while government borrowing has a crowding‐out effect. Pakistan currently faces supply constraints, which might put an additional check on capacity utilization by firms, thus damaging growth prospects. The results have important policy implications.
