Regional allocation of skills

This paper addresses three questions: (1) why does the share of skilledworkers in regional population tend to be higher in wealthier regions? (2)what determines changes in this share over time? and (3) why is it that internalmigration tends to raise average skill levels of the receiving regions relativeto that of the sending regions? I construct a two--region dynamic model withagglomeration and congestion to answer these questions. It is shown that,under certain relationship between wages and demand for land, unskilledworkers are discouraged more strongly from living in a wealthier region andare less mobile than skilled workers.

Gross – to – Net Payroll Calculation Program Human Resources Information System (HRIS), 2000

Gross-to-Net is a payroll calculator modeled after the actual payroll calculation used for state employees’ paychecks. This calculator can be used to project changes in net pay when there are changes in pay amounts, hours worked, mandatory and voluntary deductions, including all pre-tax deductions such as retirement, insurances, deferred compensation or flexible spending plans. Federal and state tax withholding, retirement rates, OASDI and Medicare (FICA) are calculated using current rates.

The wage effect of an indexation clause: Evidence from Spanish manufacturing firms

An endogenous switching model of ex-ante wage changes under indexed and non-indexed settlements is estimated for the Spanish manufacturing sector using collective bargaining firm data for the 1984-1991 period. The likelihood of indexing the settlement is higher for nationwide unions than for other union groups within the works council and increases with the expected level of inflation. For wage change equations, a common structure for indexed and non-indexed settlements is strongly rejected, showing a source of nominal rigidity. For indexed contracts, the expected ex-ante total inflation coverage is nearly complete. It is also shown that workers pay a significant ex-ante wage change premium (differential) to obtain a cost of living allowance clause. However, the realised contingent compensation exceeds such a premium for all industries. Finally, important spillover effects in wage setting and the decision to index the settlement have been detected.

Wage determination in the Spanish industry

In this paper we estimate wage equations for the Spanish industryusing time series data on 85 industrial sectors, which allows us todistinguish between aggregate and sector specific effects in wagedetermination. Industry wages respond mainly to economy wide labourmarket conditions and to a much lesser extent to sector specificproductivity gains. The size of the insider effect has not remainedstable through the sample period. The estimated equations show a strongtransitory effect of unemployment on wages, which is in accordancewith the non--stationarity of the Spanish unemployment rate. Thishysteresis effect seems well accounted for by the sharp rise in theproportion of long term unemployment.

Globalization, technology and inequality

What are the effects of international integration on inequality, both between and within countries? The growing evidence that technology is the main determinant of wage and income differences may seem to imply that the forces of globalization only play a secondary role. Such a conclusion is however premature, in that it neglects the effect of international integration on technology itself. This opuscle summarizes recent and ongoing research studying how two important aspects of globalization, trade in goods and offshoring of production, shape the distribution of income when technological progress is endogenous. It discusses the theoretical foundations and the empirical support for various mechanisms through which international integration may change the incentive to develop and adopt new technologies and how this affects wages and the return to skill around the world.

State of Iowa Workforce Plan 2006-2008,

Iowa state government, as well as other state governments, other public jurisdictions and other employers in general, finds itself at the beginning of a unique demographic phenomenon, the aging of the workforce and the concomitant mass exodus of many workers. Anticipation of this trend alone has raised the profile of and interest in workforce planning. In 2000, the Iowa Department of Personnel, the predecessor agency of the Department of Administrative Services Human Resources Enterprise (DAS-HRE), undertook several initiatives as foundational steps in establishing a workforce planning program.

Human Resource Management Succession Planning Guide, 2007

The Iowa Department of Administrative Services - Human Resources Enterprise (DAS-HRE) has developed a variety of tools and resources to address those concerns. Loss of institutional knowledge, or knowledge transfer as it is more frequently referred to, is one of the main topics of the Workforce Planning Guide. Potential difficulties finding new workers was one of the major reasons for adding a chapter on recruitment in the Applicant Screening Manual.

Offshoring and directed technical change

To study the short-run and long-run implications on wage inequality, we introducedirected technical change into a Ricardian model of offshoring. A unique final good isproduced by combining a skilled and an unskilled product, each produced from a continuumof intermediates (tasks). Some of these tasks can be transferred from a skill-abundant Westto a skill-scarce East. Profit maximization determines both the extent of offshoring andtechnological progress. Offshoring induces skill-biased technical change because it increasesthe relative price of skill-intensive products and induces technical change favoring unskilledworkers because it expands the market size for technologies complementing unskilled labor.In the empirically more relevant case, starting from low levels, an increase in offshoringopportunities triggers a transition with falling real wages for unskilled workers in the West,skill-biased technical change and rising skill premia worldwide. However, when the extentof offshoring becomes sufficiently large, further increases in offshoring induce technicalchange now biased in favor of unskilled labor because offshoring closes the gap betweenunskilled wages in the West and the East, thus limiting the power of the price effectfueling skill-biased technical change. The unequalizing impact of offshoring is thus greatestat the beginning. Transitional dynamics reveal that offshoring and technical change aresubstitutes in the short run but complements in the long run. Finally, though offshoringimproves the welfare of workers in the East, it may benefit or harm unskilled workers inthe West depending on elasticities and the equilibrium growth rate.

Globalization and wage inequality in South and East Asia, and Latin America: A gender approach

In this paper we analyse the reasons behind the evolution of the gender gap and wage inequality in South and East Asian and Latin American countries. Health human capital improvements, the exposure to free market openness and equal treatment enforcement laws seem to be the main exogenous variables affecting women s economic condition. During the second globalization era (in the years 1975-2000) different combinations of these variables in South East Asian and Latin American countries have had as a result the diminution of the gender gap. The main exception to this rule according to our data is China where economic reforms have been simultaneous to the increase of gender differences and inequality between men and women.This result has further normative consequences for the measure of economic inequality. Theimprovement of women s condition has as a result the diminution of the dispersion of wages.Therefore in most of the countries analysed the consequence of the diminution of the gender gapduring the second global era is the decrease of wage inequality both measured with Gini and Theil indexes.

Human capital and externalities in cities

We combine growth theory with US Census data on individual schooling and wages to estimate the aggregate return to human capital and human capital externalities in cities. Our estimates imply that a one-year increase in average schooling in cities increases their aggregate labor productivity by 8 to 11 percent. We find no evidence for aggregate human capital externalities in cities however althoughwe use three different approaches. Our main theoretical contribution is to show how human capital externalities can be identified (non-parametically) even if workers with different levels of human capital are imperfect substitutes in production.

Nonparametric bounds on the returns to language skills

This paper applies the theoretical literature on nonparametric bounds ontreatment effects to the estimation of how limited English proficiency (LEP)affects wages and employment opportunities for Hispanic workers in theUnited States. I analyze the identifying power of several weak assumptionson treatment response and selection, and stress the interactions between LEPand education, occupation and immigration status. I show that thecombination of two weak but credible assumptions provides informative upperbounds on the returns to language skills for certain subgroups of thepopulation. Adding age at arrival as a monotone instrumental variable alsoprovides informative lower bounds.

Ex post bargaining, labor coordination and wage formation at the firm level

We lay out a model of wage bargaining with two leading features:bargaining is ex post to relevant investments and there isindividual bargaining in firms without a Union. We compareindividual ex post bargaining to coordinated ex post bargainingand we analyze the effects on wage formation. As opposed to exante bargaining models, the costs of destroying the employmentrelationship play a crucial role in determining wages. Highfiring costs in particular yield a rent for employees. Ourtheory points to a employer size-wage effect that is independentof the production function and market power. We derive a simpleleast squares specification from the theoretical model thatallow us to estimate components of the wage premium fromcoordination. We reject the hypothesis that labor coordinationdoes not alter the extensive form of the bargaining game. Laborcoordination substantially increases bargaining power butdecreases labor's ability to pose costly threats to the firm.

How wide is the gap? An investigation of gender wage differences using quantile regression

In this paper we examine the determinants of wages and decompose theobserved differences across genders into the "explained by differentcharacteristics" and "explained by different returns components"using a sample of Spanish workers. Apart from the conditionalexpectation of wages, we estimate the conditional quantile functionsfor men and women and find that both the absolute wage gap and thepart attributed to different returns at each of the quantiles, farfrom being well represented by their counterparts at the mean, aregreater as we move up in the wage range.
