Instrumental cardinal concerns for social status in two-sided matching with non-transferable utility

In this paper we apply the instrumental approach to social preferences in order to distinguish among various shapes of preferences for social status. In particular, we consider the shape of reduced preferences that emerge in the equilibrium of a two-sided matching model with non-transferable utility. Cole et al., 1992, Cole et al., 1995 show that, under full observability of potential mates׳ attributes, instrumental concerns for social status are ordinal, i.e., only one׳s own rank in the distribution of attributes matters. We show that when we depart from full observability, instrumental concerns for social status become cardinal, i.e., also other features of the distribution of attributes matter. We also show that the actual shape of cardinal concerns depends on how individuals can deal with the informational asymmetry, alternatively leading to upward concerns, i.e., making comparisons with higher rank people; downward concerns, i.e., making comparisons with lower rank people; or bidirectional concerns, i.e, being both upward and downward.     

An economic evaluation of the Baldrige National Quality Program

All federal programs are accountable for their use of public funds. This paper presents conservative estimates of the net social benefits associated with the Baldrige National Quality Award Program, established within the National Institute of Standards and Technology in 1987. On the basis of survey data from members of the American Society for Quality, we estimate cost savings benefits to members, extrapolate those benefits to the economy as a whole, and compare the benefits to the social costs associated with the Program. Our estimation method implies that the ratio of economy-wide benefits to social costs probably exceeds 207:1, supporting the hypothesis that the public investments in quality-standards infrastructure are worthwhile.     

Landing on all fours? Communist elites in post-Soviet Russia

This paper analyzes the economic situation of former Communist party members in post-Soviet Russia. On the basis of the Russian Socio-Economic Transition Panel, we are able to identify members of the Communist party prior to transition so that we can assess their relative economic performance between 1993 and 1999. We find a significant wage premium associated with former membership in the Soviet Communist party during the period from 1993 to 1999. After addressing non-random selection into the Communist party using an instrumental variables approach, we demonstrate that the overall Communist wage premium can be attributed to positive unobservable characteristics of former party members.

A selective review of the first 20 years of instrumental variables models in health-services research and medicine

Abstract

Background:

The method of instrumental variables (IV) is useful for estimating causal effects. Intuitively, it exploits exogenous variation in the treatment, sometimes called natural experiments or instruments. This study reviews the literature in health-services research and medical research that applies the method of instrumental variables, documents trends in its use, and offers examples of various types of instruments.     

Alternative approaches to discrete working time choice in an AGE framework

We compare two options of integrating discrete working time choice of heterogenous households into a general equilibrium model. The first, known from the literature, produces household heterogeneity through a working time preference parameter. We contrast this with a model that directly incorporates a logit discrete-choice approach into an AGE framework. On the grounds of both calibration consistency and adequate accommodation of within-household interaction, we argue that the logit approach is preferable.     

Co-authorship and research productivity in economics: Assessing the assortative matching hypothesis

This paper estimates the relation between the size and quality of scientists’ co-author networks and individual characteristics (notably productivity) in the context of institutional changes in French academia in the mid-1980s. The analysis employs the Two-Stage Residual Inclusion (2SRI) framework to handle endogeneity in individual productivity relative to the quality of co-authors. The main finding is that the size and quality of authors’ networks are positively related to their productivity; this is understood as evidence of assortative matching. Other effects on co-author networks (such as life-cycles, specialties fields) are also identified. Our results have important policy implications as it indirectly demonstrates the effectiveness of career incentives linked to publication.     

Returns to women’s education using optimal IV selection

This paper investigates returns to women’s education by applying an optimal IV selection approach, post-Lasso IV estimation, which improves the first-stage predictive relationship between an endogenous regressor and instruments. Using the 2010 American Community Survey, we find that an extra year of education increases married women’s own income by $4,480 and spouse income by $8,822. Our findings indicate that 53% of the increase in women’s consumption by education is attributed to the marriage market, and thus, we conclude that the marriage market is the primary channel through which education improves women’s well-being. The results demonstrate the advantages of the post-Lasso approach: The resulting two-stage least squares estimator maintains efficiency without increasing finite sample bias and is less subject to the inconsistency problem when some instruments are invalid; This differs from the results using the instrument of birth quarters only, which is mostly applied in studies on returns to education.     

Expectations in micro data: rationality revisited

An increasing number of longitudinal data sets collect expectations information regarding a variety of future individual level events and decisions, providing researchers with the opportunity to explore expectations over micro variables in detail. We present a theoretical framework and an econometric methodology to use that type of information to test the Rational Expectations (RE) hypothesis in models of individual behavior. This RE assumption at the micro level underlies a majority of the research in applied fields in economics, and it is the common foundation of most work in dynamic models of individual behavior. We present tests of three different types of expectations using two different panel data sets that represent two very different populations. In all three cases we cannot reject the RE hypothesis. Our results support a wide variety of models in economics, and other disciplines, that assume rational behavior. We would like to acknowledge outstanding research assistance from Huan Ni.

New evidence on the effects of job creation schemes in Germany—a matching approach with threefold heterogeneity

This paper evaluates the effects of job creation schemes on the participating individuals in Germany. The very informative dataset at hand justifies the application of a matching estimator and allows to take account of threefold heterogeneity. The recently developed multiple treatment framework is used to evaluate the effects with respect to regional and individual heterogeneity as well as to differences in the programme sectors. The results show considerable differences with respect to these sources of heterogeneity, but the overall finding is very clear. At the end of our observation period, that is 2 years after the start of the programmes, participants in job creation schemes have a significantly lower success probability on the labour market in comparison to matched non-participants.     

Class-size effects in school systems around the world: Evidence from between-grade variation in TIMSS

We estimate the effect of class size on student performance in 11 countries, combining school fixed effects and instrumental variables to identify random class-size variation between two adjacent grades within individual schools. Conventional estimates of class-size effects are shown to be severely biased by the non-random placement of students between and within schools. While we find sizable beneficial effects of smaller classes in Greece and Iceland, we reject the possibility of even small effects in four countries and of large beneficial effects in an additional four countries. Noteworthy class-size effects are observed only in countries with relatively low teacher salaries.     

基于竞优评析的高层次科技人才评价

尽管各地政府和企事业单位均采取积极措施引进高层次科技人才,但实践效果却不尽如人意,其中一个重要原因在于,对高层次科技人才评价不够科学。在对高层次科技人才进行界定后,构建包括“品德、知识、能力、业绩、影响力”五位一体的高层次科技人才评价指标体系,并采用能够凸显个体优势的竞优评析法,设计出指标权重以及相应评价模型,在此基础上,对拟引进某区域中心城市的10位高层次科技人才进行评价。结果表明,竞优评析法能有效识别出高层次科技人才的个体优势,评价结果兼顾了个性化和民主性,为竞优评析法在高层次科技人才评价中的推广应用提供了支持。     

Comment on “Revealing Differences in Willingness to Pay Due to the Dimensionality of Stated Choice Designs: An Initial Assessment”

There are very few studies that quantify the interactions and tradeoffs between statistical and cognitive efficiency in designing stated-choice studies. While a conceptual framework for evaluating cognitive strategies would be desirable, Hensher adopts a strictly empirical approach in this experiment. The success of the study must be evaluated in light of his aggregating attributes rather than controlling the number of attributes, asymmetry in the narrow-range and wide-range attributes, and lack of orthogonality between the number of attributes and number of alternatives. Nevertheless, Hensher challenges uncritical acceptance of any given set of design features and correctly insists that we confirm our experience with rigorous, quantitative experiments.     

Rainy day politics. An instrumental variables approach to the effect of parties on political outcomes

Scholars have grappled with the question of how parties affect policy. Here I propose and test an instrumental variable approach using rainfall. In Norwegian municipal elections, potential left wing voters are likely to abstain from voting with election day rain, whereas the opposite holds for right-wingers. Then rainfall provides an exogenous source of variation, and hence an instrument, for the party composition of the municipal council. A strengthening of the right wing parties due to rainfall shifts expenditures toward education, but reduces total spending. This also shows that political competition does not drive party platforms to converge.     

风电场运行经济性综合评价方法

由于风力发电行业本身的特点和风电场运行管理的特殊性，任何单一的评价指标都难以对风电场运行经济性进行全面、完整、综合、客观的反映。本文采用层次分析法提出了风电场运行经济性综合评价方法。运用这种方法可以对风电场的发电情况、无功耗用情况、运行费用及人员效率情况等几个风电场运行经济性评价应考查的主要方面进行综合评价。     

转轨经济中自然垄断产业的竞争与所有制研究

竞争与所有制改革是目前自然垄断产业规制改革的主要趋势.但原有的理论和经验都是针对发达国家而言,对于转轨国家如何协调经济转轨与自然垄断产业改革却没有现成的理论与经验.因此,本文关注转轨国家自然垄断产业引入竞争可能性以及所有制改革模式的选择.研究发现:考虑管理成本,转轨国家自然垄断产业引入竞争是可能的;改革进程取决于转轨国家市场发育程度以及改革的初始条件;混合所有制的企业竞争模式更适合于转轨国家自然垄断产业的改革.     

It pays to be ignorant: A simple political economy of rigorous program evaluation

This paper attempts to explain the scarcity of rigorous evaluations of public policy. I build a positive model to explain the "stylized fact" that there is under investment in the creation of reliable empirical knowledge about the impacts of public sector actions. The model shows how "advocates" of particular issues or solutions - the public action equivalent of entrepreneurs - have incentives to under invest in knowledge creation because having credible estimates of the impact of their preferred program may undermine their ability to mobilize political (budgetary) support.     

The Carrot vs. the Stick in Work Team Motivation

This paper reports on the use of carrot (positive) and stick (negative) incentives as methods of increasing effort among members of work teams. We study teams of four members in a laboratory environment in which giving effort towards the team goal is simulated by eliciting voluntary contributions towards the provision of a public good. We test the efficiency-improving properties of four distinct environments: monetary prizes given to high contributors versus monetary fines assessed to low contributors, where high/low contributor is defined first in terms of absolute contributions and then in terms of contributions relative to abilities—which we call handicapping. Our results show that both carrot and stick can increase efficiency (i.e., contributions) levels by 10–28%. We find that handicapped incentives promise the highest efficiency levels, and when handicapping is not used penalties may be more effective than prizes. The implications for work teams and suggestions for practical implementation are discussed.     

Alternative Approaches to Commercial Property Price Indexes for Tokyo

The paper studies the problems associated with the construction of price indexes for commercial properties that could be used in the System of National Accounts. Property price indexes are required for the stocks of commercial properties in the balance sheets and related price indexes for the land and structure components of a commercial property are required in the balance sheet accounts for the calculation of the Multifactor Productivity of the Commercial Property Industry. The paper uses a variant of the builder's model that has been used to construct Residential Property Price Indexes. Geometric depreciation rates are estimated for commercial offices in Tokyo using assessment data for REIT. The problems associated with the decomposition of property value into land and structure components are addressed. The problems associated with depreciating capital expenditures on buildings and with measuring the loss of asset value due to early retirement of the structure are also addressed.
