Compensation Dispersion Between and Within Hierarchical Levels

This paper studies the dispersion around the expected compensation of workers before and after controlling for hierarchical positions in cross-section data samples. From data for Spanish managers, we find that this dispersion decreases with education and work experience before entering the current job and increases with job tenure. This finding contrasts with previous research that finds a positive association between compensation dispersion and education and work experience. We explain the new finding through a model of learning that separates compensation dispersion between jobs and within jobs (hierarchical positions). The model takes advantage of the information revealed when workers are promoted to their current hierarchical positions and allows for more robust tests of learning theories.     

Assessing Applied Protection across the World*

This paper presents MAcMap–HS‐6, a database providing a consistent, ad valorem equivalent measure of tariff duties and tariff rate quotas for 163 countries and 208 partners, at the six‐digit level of the Harmonized System (5111 products), accounting for all preferential agreements. We describe the methodology used to compute and aggregate an ad valorem equivalent of applied protection. Emphasis is placed on minimizing the endogeneity bias in the aggregation procedure, while acknowledging structural differences in export specialization. The resulting quantitative assessment is illustrated by giving an overview of applied protection across the world in 2001, in terms of average as well as distribution.     

印尼航空业起伏录

印尼政府很早就对航空业取消了管制，最初，这的确促进了航空业的繁荣，航空业发展前景喜人，印尼开放的天空中出现了众多大型外国投资商人的身影。根据印席尼西亚航空局的统计，印尼共有19家国内航空公司，向约3400万乘客提供服务。该机构预计，到2010年，每年将有5400万旅客选择飞机出行，而在1999年，这个数字仅为640万。     

Strategic participation and the median voter result

In a seminal paper on electoral equilibrium under majority rule, Ledyard (1984) demonstrates that strategic participation by voters results in an electoral equilibrium at the proposal that maximizes the utility of a randomly selected voter. Palfrey and Rosenthal (1985) limit the usefulness of this result by showing that strategic participation rates are miniscule in large electorates, and that the incentive to participate vanishes completely as the electorate grows without bound. The most reasonable modification of Ledyard’s approach that circumvents these criticisms is to allow for a negative cost of voting. We show that when voters can have even an arbitrarily small negative cost of voting, there is an electorate sufficiently large so that any proposal is defeated or tied by the median proposal. This observation raises questions about the existence of electoral equilibrium under strategic participation, and is relevant to the efficiency of elections.     

Bid‐ask spreads,volatility, quote revisions,and trades of thinly traded futures contracts

We investigate intraday bid‐ask spreads (BAS), volatility, and trading activity of thinly traded equity index futures contracts on the Singapore Exchange. Contrary to previous findings, we find a rather flat BAS pattern during the trading day. However, consistent with past findings, an increase in risk widens the spread and a higher trading activity reduces it. When trading occurs in a day, spreads are reduced. No significant difference in volatility between days with and without trades was detected. When trades occur, quote revisions increase, and it is positively related to the number of trades. An increase in the number of quote revisions increases the likelihood of a transaction, and when quotes are current, revisions that are accompanied by trades carry new information. We provide evidence that contracts that are thinly traded may possess liquidity attributes as long as their price quotes remain current. © 2003 Wiley Periodicals, Inc. Jrl Fut Mark 23:455–486, 2003
