Selection Bias In College Admissions Test Scores, Jesse Rothstein, Melissa Clark, Diane Schanzenbach

Diane Whitmore Schanzenbach

Data from college admissions tests can provide a valuable measure of student achievement, but the non-representativeness of test-takers is an important concern. We examine selectivity bias in both state-level and school-level SAT and ACT averages. The degree of selectivity may differ importantly across and within schools, and across and within states. To identify within-state selectivity, we use a control function approach that conditions on scores from a representative test. Estimates indicate strong selectivity of test-takers in "ACT states," where most college- bound students take the ACT, and much less selectivity in SAT states. To identify within- and between-school selectivity, we …

What Code-Mixed Dps Can Tell Us About Gender, Elena Valenzuela, Joyce Bruhn De Garavito, Ewelina Barski, Maria De Luna Villalón, Ana Faure, Yolanda Pangtay, Alma Ramírez Trujillo, Sonia Reis

Ewelina Barski, PhD

There has been a growing interest in the examination of the steady state of simultaneous bilinguals. An understanding of what leads to the possible weaknesses in the grammar of early bilinguals can contribute to our understanding of the possible causes of the apparent characteristic ‘failures’ in second language acquisition (Montrul 2008). Spanish has a gender feature for nouns (Carroll 1989) and gender agreement for determiners and adjectives. Problems with the acquisition of gender marking on the noun and/or with gender agreement are well-known in the L2 literature (Hawkins 1998; Fernández–Garcia 1999; Franceschina 2001; Bruhn de Garavito and White 2002; White …

Prediction Markets To Forecast Electricity Demand, Peter Cramton, Luciano De Castro

Luciano I. de Castro

Forecasting electricity demand for future years is an essential step in resource planning. A common approach is for the system operator to predict future demand from the estimates of individual distribution companies. However, the predictions thus obtained may be of poor quality, since the reporting incentives are unclear. We propose a prediction market as a form of forecasting future demand for electricity. We describe how to implement a simple prediction market for continuous variables, using only contracts based on binary variables. We also discuss specific issues concerning the implementation of such a market.

A Public Lecture: Labour Markets And Economic Development, Gary S. Fields

Gary S Fields

[Excerpt] I want to put forward three propositions to you based on decades of work in Asia, Latin America, and Africa. First, economic development can be (but need not be) a win-win-win situation - for businesses, for individuals and groups of individuals, and for governments and non- governmental organisations (NGOs). Second, the labour market can (but need not) serve as an effective mechanism for contributing to economic growth and for transmitting the gains from economic growth. And third, in both of these areas, whether a country experiences the more favorable set of outcomes or the less favorable ones reflects a) …

Dualism In The Labor Market: A Perspective On The Lewis Model After Half A Century, Gary S. Fields

Gary S Fields

This paper asks how the Lewis model might be viewed from the perspective of economic science half a century later. Many of the core propositions remain intact, some might be amplified, and a small number might be revised.

Decent Work And Development Policies, Gary S. Fields

Gary S Fields

Welcoming the shift to outcomes which he perceives in the ILO's focus on decent work, the author explores the major issues thus raised. He discusses how to make the notion of decent work more precise in operational terms, and how to develop an integrated approach to economic and social policy in the decent work context, before formulating an empirical approach to assessing the effects of economic growth on decent work. Finally, he outlines a structure for the ILO's planned country reviews of progress towards decent work.

Uncertainty, Pay For Performance, And Asymmetric Information, Felipe Balmaceda Assoc Prof.

Felipe Balmaceda

This article develops a new rationale for the emergence of pay-for-performance contracts where the labor market is competitive, workers are risk averse, and firms are risk neutral and unaware of workers’ productivities. The article shows that the prevalence of pay for performance rises and the pay-for-performance sensitivity falls as environmental uncertainty increases. This empirical regularity is unaccounted for alternative models such as the standard agency model. (JEL D86, L2, M5, J3)

Consumption Responses To In-Kind Transfers: Evidence From The Introduction Of The Food Stamp Program, Hilary Hoynes, Diane Schanzenbach

Diane Whitmore Schanzenbach

Economists have strong theoretical predictions about how in-kind transfers, such as providing vouchers for food, impact consumption. Despite the prominence of the theory, there is little empirical work on responses to in-kind transfers, and most existing work fails to support the canonical theoretical model. We employ difference-indifference methods to estimate the impact of program introduction on food spending. Consistent with predictions, we find that food stamps reduce out-of-pocket food spending and increase overall food expenditures. We also find that households are inframarginal and respond similarly to one dollar in cash income and one dollar in food stamps.

Mergers And Ceo Power, Felipe Balmaceda Assoc Prof.

Felipe Balmaceda

In this paper I propose a model of mergers in which synergies and CEO power play a crucial role. A merger is modeled as a bargaining game between the acquiring and target board of directors with the gains from a merger divided according to the generalized Nash-bargaining solution. The model's implications are consistent with the available empirical evidence on stock returns, and yield some new untested implications that are mainly related to the relationship between CEO power, cor- porate governance and mergers. Finally, the model sheds light on the relationship between aggregate merger activity, synergies and CEO power. (JEL: G34, …

[Review Of Pay Without Performance: The Unfulfilled Promise Of Executive Compensation], Kevin F. Hallock

Kevin F Hallock

[Excerpt] Every once in a while someone comes out with an important book concerning corporate governance or executive compensation. Like Aldolf A. Berle and Gardiner C. Means's The Modern Corporation and Private Property (New York: Harcourt, Brace, and World, 1932) and Graef S. Crystal's In Search of Excess: The Overcompensation of American Executives (New York: W.W. Norton, 1991), Bebchuk and Fried's new book is thought-provoking and interesting. It is a very important book and should be read not just by those interested in executive pay or corporate governance but by anyone interested in how corporations work.

[Review Of Personnel Economics In Imperfect Labour Markets], Kevin F. Hallock

Kevin F Hallock

Excerpt] This book is an attempt to consolidate what we know about Personnel Economics by focusing on Personnel Economics in Imperfect Labor Markets. Even on the first page of the book, the author is clear about this mission. In particular he notes that "The view of personnel economics analyzed in this book is based on two key properties of... labour markets: labour markets are imperfect and jobs are associated to [sic] rents; labour market institutions interact with personnel policies. Notably, wages are partly set outside the firm-worker pair (minimum wages and collective agreements are widespread)" and "job termination policies are …

Employment Fluctuations With Downward Wage Rigidity: The Role Of Worker Moral Hazard, Marcel Jansen, Jim Costain

Marcel Jansen

This paper studies the cyclical dynamics of Mortensen and Pissarides' (1994) model of job creation and destruction when workers' effort is not perfectly observable, as in Shapiro and Stiglitz (1984). An occasionally-binding no-shirking constraint truncates the real wage distribution from below, making firms' share of surplus weakly procyclical, and may thus amplify fluctuations in hiring. It may also cause a burst of inefficient firing at the onset of a recession, separating matches that no longer have sufficient surplus for incentive compatibility.

On the other hand, since marginal workers in booms know firms cannot commit to keep them in recessions, they …

A Nation In Dilemma, Professor Issam A.W. Mohamed

Professor Issam A.W. Mohamed

following the Global financial Crisis there were economic collapses in all the world. Sudan officials claimed that the country was immune from that epidemic. Such declaration were truly weird as it has been deeply affected from the first instant. That article presented many questions about the economic and social conditions and the eminent southern Sudan, Darfur crises.

Economic Performance, Creditor Protection, And Labour Inflexibility, Felipe Balmaceda Assoc Prof., Ronald Fischer Full Professor

Felipe Balmaceda

We present a static general equilibrium model of an open economy where agents are heterogeneous in terms of observable wealth and there are endogenous credit constraints due to imperfect creditor protection. Improved credit protection, harder assets, and more efficient bankruptcy procedures increase output, investment, and credit penetration. Better credit protection and harder assets lead to higher interest rate spreads. In a capital constrained (unconstrained) economy, greater (lower) wealth inequality leads to higher (lower) investment and output. Interest rate spreads are lower in richer and more unequal economies in terms of their wealth distribution. We also show that increased labour protection …

Some Remarks On The Effects Of Active Labour Market Policies In Post-Transition, Joanna Tyrowicz, Piotr Wojcik

Joanna Tyrowicz

Social cohesion is the principal goal behind active labour market policies (ALMPs), including those financed at supra-national level, like the European Social Fund. In this paper we use NUTS4 level data on the local labour market dynamics in an attempt to verify direct and indirect effects of ALMPs. We use data for 2000-2007 for Poland, while this period comprised both stark increases and reductions in the unemployment rates. Over this time also the financing of ALMPs has been increased considerably, transforming both to higher intensity of ALMPs (wider coverage) and higher extensiveness of these activities (increase in per treatment cost). …

Financial Regulation And Securitization: Evidence From Subprime Mortgage Loans, Benjamin J. Keys, Tanmoy K. Mukherjee, Amit Seru, Vikrant Vig

Benjamin J. Keys

We examine the consequences of existing regulations on the quality of mortgage loans originations in the originate to distribute (OTD) market. The information asymmetries in the OTD market can lead to moral hazard problems on the part of lenders. We find, using a plausibly exogenous source of variation in the ease of securitization, that the quality of loan originations varies inversely with the amount of regulation: more regulated lenders originate loans of worse quality. We interpret this result as possible evidence that the fragility of lightly regulated originators' capital structure can mitigate moral hazard. In addition, we find that incentives …

Examining The Obstacles To Broadening Participation In Computing: Evidence From A Survey Of Professional Workers, Ronald A. Ash, Leanne Coder, Brandon Dupont, Joshua L. Rosenbloom

Joshua L. Rosenbloom

This article describes the results of a survey of professional workers that was designed to explore the underlying reasons for the widely documented underrepresentation of women in information technology (IT) jobs. Our analysis suggests that it is different occupational personalities between men and women rather than the demanding nature of IT work that is largely responsible for the relatively few women in IT occupations. We discuss the implications these results have for policies that are designed to create greater gender equity in the rapidly growing IT industries.

The Janjaweed And The Armed Movements Of Sudan, Professor Issam A.W. Mohamed

Professor Issam A.W. Mohamed

The emergence of the Janjaweed as an armed force working with the government to suppress rebellions in Darfur region outraged the international community. They were marked by brutality, destruction, burning, killings and mass rapes. They were also described as Arabs. However, that was not the whole picture, no one observed the living conditions of the Arabs or how were they victims also as the other inhabitants of Darfur. No one also observed that they were used by the Ingaz government to execute the dirty work and bear the consequences. The Arab tribes however, also had other thoughts as they realized …

Labor-Market Regimes In U.S. Economic History, Joshua L. Rosenbloom, William A. Sundstrom

Joshua L. Rosenbloom

In much economic analysis it is a convenient fiction to suppose that changes over time in wages and employment are determined by shifts in supply or demand within a more or less competitive market framework Indeed, this framework has been effectively deployed to understand many episodes in American economic history. We argue here, however, that by minimizing the role of labor-market institutions such an approach is incomplete. Drawing on the history of American labor markets over two centuries, we argue that institutions—by which we mean both formal and informal rules that constrain the choices of economic agents—have played a significant …

Assessing The Viability Of Investment In Sudan (1979-2008), Professor Issam A.W. Mohamed

Professor Issam A.W. Mohamed

Most developing and underdeveloped countries beside Sudan suffer from low levels of income in addition to the low savings that are result from the lack of public savings channels. Hence, investments depend on the individuals' abilities on savings where they are major motivating vehicle for economic activity due to its direct correlation with capital accumulation process that increases the productive capacity for the national economy and help to create job opportunities and achieving economic development. Subsequently, the importance of the investment comes from the effective role that can be practiced on the national product. Currently, Sudan endures severe economic crisis …

Rogue Counrty And Potential Cooperation: The United States And Sudan And Feasible Economic Partnership, Professor Issam A.W. Mohamed

Professor Issam A.W. Mohamed

The United States declared Sudan as a rogue country in 1995 due to many political considerations. It has imposed many economic and political sanctions against it since that time which represented hindrance to development and resulted in economic crises. Oil explorations started long time by Total Oil Company and resumed by Chevron that halted her activities in Sudan after the flaring of the civil war between the Northern and Southern parts of the country. That work was resumed in 1996 by Chinese companies and was crowned by success and commercial production in 1999. Although the economic situations of Sudan improved …

Progress Of Participation In Tertiary Education In India From 1993 To 2004, Mehtabul Azam

Mehtabul Azam

Using nationally representative household surveys, this paper examines the trends in attainment, enrolment, and access to tertiary (higher) education in India from 1983 to 2005. The findings suggest that there has been considerable progress in attainment and participation; however, they remain low. Important gaps exist in enrolment between rich and poor, rural and urban areas, men and women, disadvantaged groups and the general population, and states. Analysis of transition rates from secondary education to tertiary education and regression analysis indicate that inequality in tertiary education between disadvantaged groups and the general population is explained by low completion rates of secondary …
