Cognitive and Non-Cognitive Impacts of High-Ability Peers in Early Years*

The sorting of students into ability groups is one of the most common, controversial and long-examined educational practices. Ability grouping also mechanically changes peer groups. We provide novel evidence on the cognitive and non-cognitive impacts in early years, of being exposed to higher-ability classroom peers through being assigned to the top within-class ability group. We exploit panel data from the UK Millennium Cohort Study, which allows us to construct trajectories of the cognitive and non-cognitive development of children from birth to entry into primary school. The data also record school grouping policies and the specific within-class group assignment of each child, by subject. We combine these rich data with an instrumental variable design using child-level variation in group assignment due to month of birth, in order to measure the local average treatment effect (LATE) of being assigned to the highest-ability peer group. We find that if a marginal student is assigned higher-ability peers, this significantly reduces their cognitive achievement in mathematics, and has no impact on literacy. There are countervailing impacts on non-cognitive outcomes for the marginal student assigned higher-ability peers: although they are more motivated to study and parents respond with an improved home learning environment, these children have more study-related difficulties and their relations with their peers significantly worsen. These findings have important policy implications for the use and design of within-class ability grouping in early years.

Making do: state constraints and local responses in California’s education finance system

California’s unique education finance system combines general state support for school districts, numerous state categorical aid programs, a restricted local property tax, and two unusual small local revenue sources: a parcel tax and contributions from educational foundations. This paper explores the incentives this system creates for local voters and school officials and estimates the impact of these incentives on education costs, school district efficiency, and the demand for student performance. The paper finds that voters in California respond to the price incentives in this system even though they work through the hard-to-pass parcel tax instead of the property tax; that educational outcomes are strongly influenced by student characteristics and other factors that influence educational costs; that school district efficiency is undermined by the state’s current emphasis on categorical instead of unrestricted aid; and that, overall, the education finance system is not well designed to meet the state’s educational objectives.     

Evaluating the Stability of School Performance Estimates over Time

When using school performance indicators for the purposes of accountability and school choice, it is very important that measures are stable over time. This issue is very relevant when the system is based on the allocation of students to the same teachers for the whole educational cycle (e.g. at primary school level). Using administrative data provided by the National Evaluation Committee for Education (INVALSI), we explore the stability of performance estimates for Italian primary schools. We first construct school performance metrics using INVALSI standardised tests, by taking advantage of a rich array of individual‐level variables (including prior achievement) that allow us to estimate a school effect in a ‘value added’ perspective. We assess differences in performance across schools and the persistence of these differences across cohorts. We find that controlling for compositional differences is important; therefore, estimates of school performances are unstable across metrics, and correlations across cohorts decline over time.     

Liquidity-Based Competition for Order Flow

We present a microstructure model of competition for order flowbetween exchanges based on liquidity provision. We find thatneither a pure limit order market (PLM) nor a hybrid specialist/limitorder market (HM) structure is competition-proof. A PLM canalways be supported in equilibrium as the dominant market (i.e.,where the hybrid limit book is empty), but an HM can also besupported, for some market parameterizations, as the dominantmarket. We also show the possible coexistence of competing markets.Order preferencing—that is, decisions about where ordersare routed when investors are indifferent—is a key determinantof market viability. Welfare comparisons show that competitionbetween exchanges can increase as well as reduce the cost ofliquidity.     

Diversification of Macroeconomic Risk and International Integration of Capital Markets: The Case of Mexico

This article tests the arbitrage pricing theory in the contextof the unstable macroeconomic years in Mexico, 1977–87.Using information on returns on assets available to domesticinvestors—primarily stocks traded at the local stock exchange—anattempt is made to ascertain the extent to which these assetshave offered premia for a set of proposed sources of risk. Thepervasive factors that play an important role in asset pricingin Mexico are unexpected inflation, unexpected money growth,innovations in the Standard & Poor's 500 price series, andinnovations in the dollar oil price. A residual market factoris obtained, using the McElroy and Burmeister model. Given thatthese risks get premia over and above the riskless rate, expectedrates of return in Mexico have been higher during the yearsof erratic macroeconomic conditions. Mexico is not consideredto be well integrated with the international capital marketsbecause local sources of risk—such as inflation—arenot priced in the United States, whereas international sourcesof uncertainty—such as oil price shocks—are pricedlocally but not in the United States.     

Credit Markets in Northern Nigeria: Credit as Insurance in a Rural Economy

This article addresses the issues of incomplete markets andimperfect information in the context of credit markets in ruralnorthern Nigeria. In much recent theoretical literature, theproblems of moral hazard and adverse selection are assumed tobe decisive for the organization of agrarian institutions. Incontrast, it is found that in the four villages surveyed credittransactions take advantage of the free flow of informationwithin rural communities. Information asymmetries between borrowerand lender are unimportant, and their institutional consequences—theuse of collateral and interlinked contracts—are absent.Credit transactions play a direct role in pooling risk betweenhouseholds through the use of contracts in which the repaymentowed by the borrower depends on the realization of random productionshocks by both the borrower and the lender.     

Student Outcomes in Philippine Elementary Schools: An Evaluation of Four Experiments

Policymakers in most developing countries are concerned abouthigh dropout rates and poor student learning in primary education.The government of the Philippines initiated the Dropout InterventionProgram in 1990–92 as part of its effort to address theseissues. Under this program, four experimental interventionswere randomly assigned to 20 schools in selected low-incomeareas. Pre- and post-intervention data were collected from theseschools, as well as from 10 control schools, in order to evaluatethe program's impact on dropout behavior and student learning.The economic justification for replication appears to be strongestfor the interventions that provided teachers with learning materials,which helped them to pace lessons according to students' differingabilities, and that initiated parent-teacher partnerships, whichinvolved parents in the schooling of their children. The justificationwas weakest for the school feeding intervention. In additionto the results specific to the Philippines, this research demonstratesthe feasibility of monitoring and evaluating interventions inthe education sector in other developing countries, includingthe use of randomized control designs.     

Pricing and Hedging Discount Bond Options in the Presence of Model Risk

This paper focuses on pricing and hedging options on a zero-couponbond in a Heath—Jarrow—Morton (1992) framework whenthe value and/or functional form of forward interest rates volatilityis unknown, but is assumed to lie between two fixed values.Due to the link existing between the drift and the diffusioncoefficients of the forward rates in the Heath, Jarrow and Mortonframework, this is equivalent to hedging and pricing the optionwhen the underlying interest rate model is unknown. We showthat a continuous range of option prices consistent with noarbitrage exist. This range is bounded by the smallest upper-hedgingstrategy and the largest lower-hedging strategy prices, whichare characterized as the solutions of two non—linear partialdifferential equations. We also discuss several pricing andhedging illustrations.     

Accounting education research: a retrospective over ten years with some pointers to the future

Abstract

This paper proposes principles to guide accounting students' and accounting educators' use of Facebook as an educational resource to engage students with their learning. A body of cross-disciplinary research has investigated potential applications of Facebook to invigorate student engagement. Generic guidelines for educators who are contemplating integrating Facebook into pedagogical practice are a recent addition to this research. However, there is a lack of disciplinary-specific guidelines to inform both accounting educators' and accounting students' use of Facebook as a learning resource. Indeed, Facebook's pedagogical affordances are a generally overlooked field of enquiry in accounting education research. The principles proposed in the paper are informed by the literature on Facebook and student engagement, and the concept of digital citizenship, which illuminates the importance of the responsible and professional use of Facebook by accounting students and the development of online practices and behaviours that enhance students' appeal to the accounting profession.     

Economic Reform and Labor Unions: A General-Equilibrium Analysis Applied to Bangladesh and Indonesia

Noting the trend toward more independent trade unions in developingcountries, this article examines whether the presence of unionsstrengthens or weakens the benefits to be gained from economicpolicy reform. We show that the presence of "passive" unions—onesthat choose their wage-employment contract given the firm'scost-minimizing strategy—increases the welfare gains fromtrade liberalization, because trade reform lowers the wage premiumenjoyed by the unionized sector, reducing a distortion in thelabor market. These gains are amplified when the unions are"active", namely, when they negotiate a contract with the firmthat is off its labor demand curve. Such a contract resultsin featherbedding—paying workers more than their marginalproduct—and trade reform reduces the amount of featherbedding.The policy implication for Bangladesh—a country with strongtrade unions and a protected unionized sector—is thatthe benefits of further trade liberalization may be greaterthan otherwise predicted. In Indonesia, where both unionizationand import tariffs are low, allowing greater independence tounions may preserve flexibility and reward workers better thanthe current minimum-wage policy.     

REFORMING FINANCE IN TRANSITIONAL SOCIALIST ECONOMIES

Financial reforms initiated in most transitional socialist economiesdo not yet adequately provide many of the financial servicesassociated with market-oriented financial systems. Such services—mobilizingresources, selecting firms and allocating capital, monitoringfirm managers, and facilitating the management of transactionsand risk—are a necessary condition for economic reformto improve living standards. This article envisages four central strategies to guide reformof the financial sector: • Building an infrastructure based on clear and enforceableproperty rights, modern accounting and auditing standards, reliablepayments systems, sound prudential and enforcement regulations,and professionals trained in finance • Ending the shell game of trying to hide the losses ofstate-owned enterprises, and separating government decisionsto finance "priority" firms from the allocation decisions ofindependent financial institutions • Privatizing some financial institutions early—althoughnot necessarily precipitously—in concert with the privatizationof firms and supervisory capabilities, meanwhile cleaning upbank loans to maximize the chances that firms and banks willsucceed as private entities • Improving the tax system and stressing a prudent interestrate policy to reduce uncertainty, distortions, and excessiverepression of the financial sector.      

Policy Selectivity Forgone: Debt and Donor Behavior in Africa

We assess the dynamics behind the high net resource transfersby donors and creditors to Sub-Saharan African countries. Analyzingthe determinants of overall net transfers for a panel of 37recipient countries in 1978–98, we find that country policiesmattered little. Donors—especially bilateral donors—actuallymade greater transfers to countries with high debt, largelyowed to multilateral creditors, when policies were "bad." Weconclude that comprehensive debt relief has the potential, thoughnot the certainty, to restore selectivity in support of goodpolicies. That would make development assistance more effectivegoing forward—and increase public support in donor countries.     

EDUCATION VOUCHERS IN PRINCIPLE AND PRACTICE: A SURVEY

An education voucher system exists when governments make paymentsto families that enable their children to enter public or privateschools of their choice. The tax-funded payments can be madedirectly to parents or indirectly to the selected schools; theirpurpose is to increase parental choice, to promote school competition,and to allow low-income families access to private schools.Some opponents predict that vouchers will destroy the publicsystem, aggravate poverty, and foster segregation. Others fearthat voucher-receiving independent schools will be regulatedout of recognition. The main purpose of this article is to examine the recent emergenceof voucher systems as an interesting phenomenon in its own right.The evidence summarized relates to voucher systems operatingin twenty countries, provinces, and states. The typical "funds-follow-the-child"voucher system, in which governments subsidize "schools of choice"in strict proportion to enrollment, appears to be the favoriteform. This type of voucher has been adopted by developing countries—notablyBangladesh, Belize, Chile, Colombia, Guatemala, and Lesotho—aswell as by industrial countries such as Poland, Sweden, theUnited Kingdom, and the United States. Much of the recordedexperience with such programs is pertinent to the longstandingtheoretical debates on the desirability of voucher systems.      

Price Informativeness and Investment Sensitivity to Stock Price

The article shows that two measures of the amount of privateinformation in stock price—price nonsynchronicity andprobability of informed trading (PIN)—have a strong positiveeffect on the sensitivity of corporate investment to stock price.Moreover, the effect is robust to the inclusion of controlsfor managerial information and for other information-relatedvariables. The results suggest that firm managers learn fromthe private information in stock price about their own firms’fundamentals and incorporate this information in the corporateinvestment decisions. We relate our findings to an alternativeexplanation for the investment-to-price sensitivity, namelythat it is generated by capital constraints, and show that boththe learning channel and the alternative channel contributeto this sensitivity.

INCOMPLETE MARKETS AND COMMODITY-LINKED FINANCE IN DEVELOPING COUNTRIES

This article provides a framework for appraising new financialinstruments and evaluating the extent to which they can helpalleviate problems of incomplete credit markets and contingentclaims markets in developing countries. Although the issuesinvolved apply to any new financial instrument, we give particularattention to commodity-linked securities because many developingcountries specialize in producing a handful of primary commoditiesand are therefore exposed to substantial commodity price risks.The article looks at the supply of, demand for, and pricingof commodity-linked securities and discusses some issues thataffect their use by developing countries: their special legalstatus as sovereign debt; their feasibility (since to becometruly effective they will require liquid secondary markets);and the construction of an optimal portfolio of external debtobligations. It also discusses the potential for new financialinstruments—particularly commodity-linked securities—asa tool for risk management in developing countries.      

Insights on Development from the Economics of Happiness

The literature on the economics of happiness in developed economiesfinds discrepancies between reported measures of well-beingand income measures. One is the so-called Easterlin paradox:that average happiness levels do not increase as countries growwealthier. This article explores how that paradox—andsurvey research on reported well-being in general—canprovide insights into the gaps between standard measures ofeconomic development and individual assessments of welfare.Analysis of research on reported well-being in Latin Americaand Russia finds notable discrepancies between respondents’assessments of their own well-being and income- or expenditure-basedmeasures. Accepting a wide margin for error in both types ofmeasures, the article posits that taking such discrepanciesinto account may improve the understanding of development outcomesby providing a broader view on well-being than do income- orexpenditure-based measures alone. It suggests particular areaswhere research on reported well-being has the most potentialto contribute. Yet the article also notes that some interpretationsof happiness research—psychologists’ set point theory,in particular—may be quite limited in their applicationto development questions and cautions against the direct translationof results of happiness surveys into policy recommendations.      

The plight of accounting education in Australia: a sense of déjà vu

Abstract

Advocates of the case method in accounting education have provided strong arguments in favour of this classroom approach. However, a primary objection has been unanswered. Cases generate ‘canned’ solutions that, when passed between students, jeopardize the accountability of individual efforts and the educational value of the exercise. Although students have leveraged computer technology to exacerbate this problem, academic staff generally have not ‘fought fire with fire.’ This paper shows how computer technology, through the use of artificial intelligence, can restore the confidence that each student will work his/her own case solution and, therefore, will extract the intended educational value from the effort. With computer technology made to act intelligently, the case method in accounting classes should become more robust as a primary pedagogical device.     

A forecast of achievement from student profile data

A compelling case has been made by accounting leaders for the increased use of groups to enhance learning in the classroom. If an instructor wants to form groups based on achievement or skill levels at the beginning of an accounting course, the purpose of this paper is to show that achievement levels can be forecast from profile data obtained from students on the first day of class. Specifically, results of this study indicate that the intent of a student to major in accounting and the grade he or she made in Introductory Financial Accounting provide an accurate forecast of the achievement of that student in Introductory Managerial Accounting. Additionally, the study's findings suggest there is some basis for a template that can be applied to forecast achievement levels of students in other accounting courses.     

Counting the World's Poor: Problems and Possible Solutions

As recent discussions have made clear, the apparent lack ofpoverty reduction in the face of historically high rates ofeconomic growth—both in the world as a whole and in specificcountries (most notably India)—provides fuel for the argumentthat economic growth does little to reduce poverty. How confidentcan we be that the data actually support these inferences? Atthe international level, the regular revision of purchasingpower parity exchange rates plays havoc with the poverty estimates,changing them in ways that have little or nothing to do withthe actual experience of the poor. At the domestic level, theproblems in measuring poverty are important not only for theworld count but also for tracking income poverty within individualcountries. Yet, in many countries, there are large and growingdiscrepancies between the survey data—the source of povertycounts—and the national accounts—the source of themeasure of economic growth. Thus economic growth, as measured,has at best a weak relationship with poverty, as measured.
