Estimating the wage costs of inter- and intra- sectoral adjustment

Estimating the Wage Costs of Inter- and Intra-Sectoral Adjustment. — The proposition that labour market adjustments to intra-industry trade are less costly than adjustments to inter-industry trade is a widely-held belief amongst trade economists. If there are significant sector-specific skills, then this ‘smooth adjustment hypothesis’ seems intuitive. Direct evidence relating to this issue remains largely anecdotal. In this paper we estimate the returns to tenure within jobs, industries and occupations in order to predict the costs, in terms of wage losses, of moving jobs between and within sectors. We find no compelling evidence that wage costs of moving between industries are larger than the costs of moving within industries.

Innovation, international R&D spillovers and the sectoral heterogeneity of knowledge flows

We analyze the relative effects of national and international, intrasectoral and intersectoral R&D spillovers on innovative activity in six large, industrialized countries over the period 1980–2000. We use patent applications at the European Patent Office to measure innovation and their citations to trace knowledge flows within and across 135 narrowly defined technological fields. Using panel cointegration we show that intersectoral spillovers have a key impact on innovation activities and that domestic R&D has a stronger effect than international R&D. However, within technological fields, estimated international R&D spillovers are 2.4 times the national R&D effects. We find significant differences across chemicals, electronics and machinery industries.     

Joint product signals of quality

Summary The relationship between product quality, signals, and the firm's optimal pricing policy has been given much attention in economics. The literature is extended in this paper by considering the signaling problem of a firm that jointly produces two commodities—one of known quality to consumers (a search good) and one of unknown quality (an experience good). The model presented employs a stylized reputation function, a linear cost structure, and linear demand schedules to produce two interesting insights. First, the search good's price can potentially be used as a signal of the quality of the experience good. Second, the price of a search good will depend upon whether it is jointly produced with another search good or an experience good or whether it is produced in isolation by a single product firm. Furthermore, evidence from a paper on gasoline pricing seems to support this contention.     

Robust Taylor rules under heterogeneity in currency trade

It is demonstrated in this paper that the exchange rate should be included in the Taylor rule when there is heterogeneity in currency trade to have a determinate and least squares learnable rational expectations equilibrium that also is desirable in an inflation rate targeting regime. Moreover, for certain Taylor rule parameterizations, these properties of the interest rate rule are robust against the degree of technical trading in currency trading.     

Cyclically oscillating product quality: A simple model of the product life cycle

This paper presents a dynamic model of the firm, where the firm can exert influence on demand by setting the price and by controlling the quality index. Assuming profit maximization, it is shown by means of the Hopf Bifurcation theorem that persistent oscillations of the variables may occur if there is positive growth at the steady state together with a high discount rate. Oscillations may also occur if the influence of an additional unit of the quality index on demand and price is sufficiently large, thus yielding a special version of the product life cycle. A numerical example is used in order to illustrate the results derived in the general framework. Valuable comments from an anonymous referee are gratefully acknowledged.     

Pricing to market, firm heterogeneity and the role of quality

We build a pricing-to-market (PTM) model with firm heterogeneity, which allows for imperfect competition and market segmentation in the presence of flexible exchange rates, horizontal and vertical differentiation and different tastes of consumers in destination markets. We derive firm’s pricing behaviour in response to price and quality competition shocks. We show that there is PTM heterogeneity across firms if quality has a role. We empirically assess the main predictions of our theoretical framework on Italian firm-level data. We document that export-domestic price margins are significantly affected by price and quality competitiveness factors even controlling for foreign demand conditions, size, export intensity, destination markets and unobservables. Finally, we provide evidence of strong heterogeneity across firms in their reaction to price and quality competitiveness.     

谈“假冒伪劣商品”的暴利与风险

一、从“阜阳劣质奶粉”事件谈起 阜阳劣质奶粉事件震动了全国，由此也引起人们对假冒伪劣商品的重新关注。本次事件不得不让我们注意到一个新问题：假冒伪劣商品对农村消费群体的危害十分严重。事实上，近些年来，许多地方的农村市场成为假冒伪劣商品的倾销地。这些假冒伪劣商品中相当一部分就是与人们的健康密切相关的食品，甚至是人命关天的药品。而农民则开始成为了假冒伪劣商品的基本消费者和主要的受害者．     

提高产品质量是扩大内需的基础性工作

产品质量低劣使消费者缺乏对国货的认同力,妨碍企业特别是个体户的正常经营,加大消费者的购物成本,降低农民购买力,增强人们的不确定性和消费支出预期,抬升企业生产经营成本,抑制财政政策发挥效益,是制约我国扩大内需的重大因素。应通过充分利用科学技术,实行严格的质量检测标准和产品检验制度,强调职工的敬业精神,认真执行《消费者权益保护法》,提高人们的质量意识等措施,进一步提高产品质量。

Links between urbanization and sectoral shifts in employment in Java

The relationship between urbanization and changes in the employment structure in Indonesia is analyzed. In particular, the author examines whether changes in the occupational structure in rural areas can have any effect in slowing the general shift in economic emphasis to urban areas, whether nonagricultural economic activities can be developed in rural areas, and what policies are needed to assist the transformation of the rural employment sector. Data are primarily from Indonesian censuses, including the 1980 census.     

Explaining sectoral discrepancies between national and provincial statistics in China

This paper examines sectoral contributions to discrepancies between China's national aggregate statistical values and the sum of provincial figures. In institutional terms, the paper then explores the sources of principally sectoral discrepancies. We find that the industrial sector has been the major contributor to discrepancies in both gross domestic product (GDP) and total energy consumption in recent years. Technical aspects such as statistical coverage, data collection method, and double-counting cannot explain the discrepancy. For the industrial sector, limited data accessibility undermines external checks and balances from the general public. As the primary bodies in collecting industrial data, the Provincial Bureaus of Statistics (PBSs) are not subject to effective internal checks and balances from other governmental divisions. To out-compete counterparts and get promoted, provincial leaders have explicit incentives to overstate provincial GDP, with industrial added value being the first statistic to be affected. This dynamic further extends to industrial energy consumption, which is over-reported as well.     

International spillover effects of sectoral tax differentiation in unionized economies

Sectoral tax differentiation has in recent years appeared onthe agenda in European policy discussions concerning unemployment.The member countries of the European Union are allowed to reducethe value added tax rates on goods and services that are particularlylabour intensive and price elastic. This paper provides a theoreticalanalysis of the international repercussions of such policies.We develop a two-country and two-sector model with monopolisticcompetition in the goods market and wage bargaining in the labourmarket. Policy externalities operate through the endogenouslydetermined terms of trade. We examine how national and supranationalcommodity tax policies affect sectoral and total employmentand characterize optimal commodity taxes with and without internationalpolicy cooperation. Some rough estimates of the welfare gainsfrom policy coordination are also presented, using a calibratedversion of the model.     

PPP视阈下农村公共文化产品及服务的供给研究

农村公共文化产品及服务体系是公共文化服务体系的组成部分,是新农村建设的重要内容。目前,我国农村公共文化产品及服务的供给失衡,究其原因,主要是由于农村公共文化产品及服务的供给模式存在严重缺陷。与传统供给模式相比,在PPP模式下,农村公共文化产品及服务建造商和运营商建立起了合作关系,从而有效减少运营成本并提高运营效率。因此,PPP模式的引入,不仅可以改善农村公共文化产品及服务供给不足的现状,而且有助于促进文化产业的发展和推动新农村建设。     

公共产品背景下政府发展学前教育的经济分析

现实中政府广泛地为社会提供基本的、均等的学前教育服务,从应然的角度来说,其依据并不是基于准公共产品,而是着眼于保障人权的社会公平,维护社会稳定和谐与缩小竞争起点差距的机会公正;从实然的角度来看,作为个体或家庭消费品的学前教育应交由市场发挥基础性作用;从非竞争性、非排他性以及正外部性的角度来看,学前教育并非完全为公共产品,而是具备私人产品部分属性,市场可作为资源配置的天然平台。     

Exchange rate volatility,sectoral trade,and the aggregation bias

This paper proposes a sectoral theoretical model in an imperfect competition framework, with country-specific and industry-specific original variables, notably factor productivity, scale economies, or product differentiation. It is then empirically estimated in a panel data model, at a sectoral and geographical disaggregation level, to test the impact of exchange rate volatility on G-7 countries' exports. Economies of scale are estimated from a non-linear translog production system. Two exchange rate volatility measurements have been used: the moving sample standard deviation and the GARCH approach. The main finding shows that the impact of exchange rate volatility on exports varies considerably, depending on the industry covered and the export destination markets. As a consequence, there is both a sectoral and geographical aggregation bias when estimating the effects of exchange rate variations. JEL no. F1, F12, F14     

The link between macroeconomic adjustment and sectoral output in post-reform China

We construct a two-part model of the Chinese economy. The first part consists of a money supply equation, a real money demand equation, and a savings equation. The second part comprises a set of sectoral equations. The model estimated is then used to generate a dynamic simulation of the paths of real national income, the aggregate price level, sectoral output, and sectoral prices. The model tracks quite well within sample, thus indicating that it may be used to analyze the future effects of policy changes. We therefore carry out counterfactual policy simulations based on monetary changes.
