Tariff pass-through and the distributional effects of trade liberalization

This paper estimates the distribution of welfare gains due to the trade reforms in India by simultaneously considering the effect on prices of tradable goods and wages. The cost of consumption for each household is affected by the domestic price changes, while wage incomes adjust to these price changes in equilibrium. Three rounds of the Indian Employment and Consumption Surveys are used for the analysis. The price transmission mechanisms are estimated for both rural and urban areas to understand the extent to which the trade reforms are able to affect the domestic prices. In order to assess the distributional effects, a series of nonparametric local linear regressions are estimated. The findings show that households at all per capita expenditure levels had experienced gains as a result of the trade liberalization, while the average effect was generally pro-poor and varied significantly across the per capita expenditure spectrum.     

Assessing the Impact of Formal and Informal Regulations on Environmental and Economic Performance of Brazilian Manufacturing Firms

This study investigates the impact of formal and informal regulations on environmental and economic performance of Brazilian manufacturing firms. We adopt a dual approach where production technology is represented by a cost function, approximated by a translog form. Pollution is considered as a negative by-product that can be modified trough using either formal regulation (inspections or sanctions) or informal regulation (community pressure). A simultaneous equation model is estimated by three-stage least squares on a sample of 404 industrial establishments located in the state of S?o Paulo, Brazil. We show that pollution abatement costs for the Brazilian manufacturing sector are different from zero which suggests that pollution emissions are affected by environmental regulation. We also demonstrate that environmental performance of firms is jointly affected by formal and informal regulation. Lastly, formal regulation is largely influenced by informal regulation and more specifically by community pressure.     

Competition for attention in the Information (overload) Age

The Information Age has a surfeit of information received relative to what is processed. We model multiple sectors competing for consumer attention, with competition in price within each sector. Sector advertising levels follow a constant elasticity of substitution (CES) form, and within‐sector prices are dispersed with a truncated Pareto distribution. The “information hump” shows highest ad levels for intermediate attention levels. Overall, advertising is excessive, although the allocation across sectors is optimal. The blame for information overload falls most on product categories with low information transmission costs and low profits.     

Financialization as a strategy of workplace control in professional service firms

Recently, there has been an increased focus on finance as a form of control in corporations. In this paper, we explore financialization as an employee control strategy in a Big Four accountancy firm, and more specifically how it affects the everyday lives of the professionals within the firm. We found financialization involved attempts to transform employees working lives into an investment activity where work was experienced as ‘billable hours’ that are ‘invested’ in the hope of a high future pay-off. Employees sought to increase the value of their investment by skilful manipulation. If wisely managed, this investment could yield significant benefits in the future. We argue that financialization involves active employee participation and is a way of binding other forms of control together.     

The Stochastic Seasonal Behaviour of Natural Gas Prices

Previous studies have explored the seasonal behaviour of commodity prices as a deterministic factor. This paper goes further by proposing a general (n+2m)‐factor model for the stochastic behaviour of commodity prices, which nests the deterministic seasonal model by Sorensen (2002) . We consider seasonality as a stochastic factor, with n non‐seasonal and m seasonal factors. The non‐seasonal factors are as defined in Schwartz (1997) , Schwartz and Smith (2000) and Cortazar and Schwartz (2003) . The seasonal factors are trigonometric components generated by stochastic processes. The model has been applied to the Henry Hub natural gas futures contracts listed by NYMEX. We find that models allowing for stochastic seasonality outperform standard models with deterministic seasonality. We obtain similar results with other energy commodities. Moreover, we find that stochastic seasonality implies that the volatility of futures returns follows a seasonal pattern. This result has important implications in terms of option pricing.     

中国城镇不同所有制企业职工收入差距的变化趋势

本文利用最新发布的CHIP-2007和CHIP-2002分析了2002年到2007年中国城镇不同所有制企业职工收入差距的变化趋势。我们发现这段时期不同所有制企业的收入差距正在减小,且这种收敛的趋势更有利于非国有企业职工,这与1995年到2002年的变化趋势形成鲜明对比。当我们分解收入差距时,发现个体的特征或能力的差别对于解释收入差距的重要性在显著提高。此外,市场分割对于不同所有制的企业仍然存在,特别对于高收入群体,但有逐步缩小的趋势。     

Induced and Linguistic Generalized Aggregation Operators and Their Application in Linguistic Group Decision Making

We introduce a wide range of induced and linguistic generalized aggregation operators. First, we present the induced linguistic generalized ordered weighted averaging (ILGOWA) operator. It is a generalization of the OWA operator that uses linguistic variables, order inducing variables and generalized means in order to provide a more general formulation. One of its main results is that it includes a wide range of linguistic aggregation operators such as the induced linguistic OWA (ILOWA), the induced linguistic OWG (ILOWG) and the linguistic generalized OWA (LGOWA) operator. We further generalize the ILGOWA operator by using quasi-arithmetic means obtaining the induced linguistic quasi-arithmetic OWA (Quasi-ILOWA) operator and by using hybrid averages forming the induced linguistic generalized hybrid average (ILGHA) operator. We also present a further extension with Choquet integrals. We call it the induced linguistic generalized Choquet integral aggregation (ILGCIA). We end the paper with an application of the new approach in a linguistic group decision making problem.     

Agricultural commodities pricing model applied to the Brazilian sugar market

This article suggests a pricing model for commodities used to produce biofuel. The model is based on the concept that the deterministic component of the Wiener process is not constant and depends on time and exogenous variables. The model, which incorporates theory of storage, the convenience yield and the seasonality of harvests, was applied in the Brazilian sugar market. After predictions were made with the Kalman filter, the model produced results that were statistically more accurate than those returned by the two‐factor model available in the literature.     

When your contract manufacturer becomes your competitor

PC maker Lenovo started out as a distributor of equipment made by IBM and other companies; now it has formed a joint venture with IBM and will eventually affix its own logo to its computers. Shanghai Automotive Industry Corporation (SAIC) started out manufacturing vehicles for Volkswagen and GM; now it's preparing to sell its own cars in China, Europe, and North America. Lenovo and SAIC represent a host of formerly anonymous makers of brand-name products that are breaking out of their defined roles and pushing the brands themselves aside. In this article, the authors explore the double-edged relationships original equipment manufacturers (OEMs) forge with their contract manufacturers (CMs). On the one hand, an OEM can reduce its labor costs, free up capital, and improve worker productivity by outsourcing all the manufacturing of a product. The company can then concentrate on value-adding activities--research and development, product design, and marketing, for instance. On the other hand, an OEM that retains a contract manufacturer may find itself immersed in a melodrama replete with promiscuity (the ambitious CM pursues liaisons with other OEMs), infidelity (the OEM's retailers and distributors shift their business to the upstart CM), and betrayal (the brazen CM transmits the OEM's intellectual property to the OEM's rivals or keeps it for itself when the contract is up). OEMs cannot simply terminate their outsourcing arrangements--they need contract manufacturers in order to keep specializing, adding value, and staying competitive. But OEMs can manage these relationships so that they don't become weak or the CMs too strong. Doing so requires modesty about revealing trade secrets; caution about whom one consorts with; and a judicious degree of intimacy, loyalty, and generosity toward partners and customers.
