heterogeneity tournaments and hierarchies tournament contracts are characterized that simultaneously elicit first best efficient effort levels and self selection of risk neutral heterogeneous workers into ability specific contracts comparisons across self selected ability types are shown to be sometimes necessary to attain efficiency rationales are explored for not commonly observing such contracts in hierarchical organizations

promotions and incentives in partnerships evidence from major u s law firms this paper develops a model of promotions in partnerships and estimates the model using cross sectional data on major u s law firms promotions to partner screen associates for firm specific skills and they generate tournament incentives among associates competing for promotions the key parameters of the model are estimated by imposing the equilibrium restriction that firms offer equal utility to incoming associates the incentive component of compensation is found to be statistically significant and a nested model without promotion

dynamic sustainability assessment the case of russia in the period of transition 1985 2008 abstract russia has experienced twenty years of economic and social change which had a substantial impact on the regional and sectoral patterns of the development of its economy infrastructure the quality of the environment and the well being of its people the current economic revival offers new opportunities and presents new challenges for the sustainable development of russia the paper employs the un sustainable development framework of indicators and assesses sustainability of russia using multi criteria evaluation methods namely the uncertainty randomization multi criteria evaluation method analysis and synthesis of parameters under information deficiency aspid the analysis covers economic environmental and social trends in russia s development in 1985 2008 and assesses sustainability of this development from the point of view of multiple criteria the results show the potential of employment of multi criteria methods for the sustainability assessment at the macro level and offer useful insights into multidimensional nature of sustainability and the role of priority setting in the evaluation process such an analysis reveals the degree of harmoniousness of sustainable development policy it shows how different sets of priorities determine the outcome of multidimensional analysis of sustainability and could potentially help in assessing progress and designing new policy instruments this paper is one of the first to apply multi criteria methods to the macro sustainability analysis in the dynamic setting

barriers and opportunities for alternative measures of economic welfare this paper explores a number of barriers and opportunities facing alternative measures of economic welfare by conducting semi structured in depth interviews with potential users in both belgium and germany the barriers that they identified are grouped into three categories context factors are embedded in the policy context and agendas that shape the environment in which an indicator percolates indicator factors depend on specific characteristics of the indicators while user factors relate to the level of experience and expertise of the users of indicators and the institutional culture in which they operate drawing on the different barriers that are reported we identify four opportunities to increase the policy value of alternative measures of economic welfare harmonizing and updating the methodological framework extending macroeconomic models to include a wider range of welfare related items improving the communication around these indicators and promoting indicator and researcher entrepreneurship these opportunities should be regarded as recommendations to the scientific community that works on these alternative measures the process of overcoming the different barriers listed in this paper should not be insurmountable as there is clear international public support for using health social and environmental statistics as well as economic statistics to measure societal progress and human well being

incentivizing r d prize or subsidies abstract this paper studies the optimal design of r d contests a sponsor e g the us department of defense or the world health organization wants to improve the quality of the winning products to do so it partitions its budget between two schemes an inducement prize and efficiency enhancing subsidies to the firms competing in the contest prizes and subsidies have different functions and they provide complementary incentives in the optimally designed contest subsidies increase while the prize decreases if the innovation process is more challenging further sensible conditions are identified under which the optimal contest implements either a handicapping scheme by preferentially subsidizing the underdog or a national champion scheme by favoring the favorite our analysis yields a number of useful implications and sheds light on an array of r d incentive schemes such as the dod s design competitions and vaccine development incentives

managerial incentive problems a dynamic perspective the paper studies how a person s concern for a future career may influence his or her incentives to put in effort or make decisions on the job in the model the person s productive abilities are revealed over time through observations of performance there are no explicit output contingent contracts but since the wage in each period is based on expected output and expected output depends on assessed ability an implicit contract links today s performance to future wages an incentive problem arises from the person s ability and desire to influence the learning process and therefore the wage process by taking unobserved actions that affect today s performance the fundamental incongruity in preferences is between the individual s concern for human capital returns and the firm s concern for financial returns the two need be only weakly related it is shown that career motives can be beneficial as well as detrimental depending on how well the two kinds of capital returns are aligned it is well understood by now that informational externalities may place special demands on the organization of economic exchange simple price mediated markets will frequently fail in the presence of asymmetric information in that case more elaborate contractual arrangements have to be used as substitutes for the price system lately considerable effort has been devoted to the analysis of contracting under incomplete information with the objective to understand the range of economic institutions that emerge in response to the failure of the price system the analysis of moral hazard has played a prominent role in this development moral hazard problems arise when for some reason or another transacting parties cannot contract contingent on the delivery of the good for instance in buying labour services it may be that the amount of labour supplied is not directly observable precluding a simple exchange of wage for labour as a partial remedy to this problem an imperfect mutually observed signal about the supply of labour can be used as a proxy in the contract frequently output is taken as such a proxy the drawback is that output is often influenced by other factors than labour input which induce undesirable risk into the contract one is therefore faced with a tradeoff between allocating risk associated with incomplete observability and providing incentives for a proper supply of labour gaining insight into this tradeoff is important not only for understanding contracting in the small e g managerial incentive schemes but also because it is closely related to the fundamental tension between equity and efficiency in the society as a whole while our understanding of moral hazard has advanced a lot in past years it is clear that much work remains an important question that has received little attention until

an extreme value model of concept testing we model concept testing in new product development as a search for the most profitable solution to a design problem when allocating resources developers must balance the cost of testing multiple designs against the potential profits that may result we propose extreme value theory as a mathematical abstraction of the concept testing process we investigate the trade off between the benefits and costs of parallel concept testing and derive closed form solutions for the case of profits that follow extreme value distributions we analyze the roles of the scale and tail shape parameters of the profit distribution as well as the cost of testing in determining the optimal number of tests and total budget for the concept phase of npd using an example we illustrate how to estimate and interpret the scale and tail shape parameters we find that the impact of declining concept testing costs on expected profits the number of concepts tested and total spending depend on the scale cost ratio and tail shape parameter of the profit distribution

career concerns contracts and effort distortions a two period career concerns model with symmetric information but uncertainty about each worker s ability is analyzed contracts are unobservable but incomes are observable it is shown that effort is distorted upward by contracts being unobservable and that the distortion depends positively on turnover

net national product as an indicator of sustainability net national product nnp can potentially serve several objectives among others to measure value added and to be an indicator of welfare in the aftermath of the world commission on environment and development however it also seems important to investigate whether the concept of nnp can serve as an indicator of sustainability my point of departure following hicks 1946 ch 14 is therefore to require that nnp should measure what can be consumed in the present period without reducing future consumption possibilities and in line with this to argue that the nnp should equal the maximum per capita consumption level that can be sustained if sufficiently many facilitating assumptions are made then a concept of nnp that serves as an exact indicator of sustainability can easily be constructed for instance for a closed economy with a constant population a stationary technology and with only one capital good it follows that the present does not reduce future consumption possibilities if and only if it does not decrease the stock of the single capital good hence under the assumption that the one capital good k is identical to the one consumption good x nnp defined as y x k measures the maximal sustainable consumption at time t because then x y is equivalent to k the purpose of this note is to establish that with multiple capital goods it is not in general possible to construct an exact indicator of sustainability on the

the optimal allocation of prizes in contests we study a contest with multiple not necessarily equal prizes contestants have private information about an ability parameter that affects their costs of bidding the contestant with the highest bid wins the first prize the contestant with the second highest bid wins the second prize and so on until all the prizes are allocated all contestants incur their respective costs of bidding the contest s designer maximizes the expected sum of bids our main results are 1 we display bidding equlibria for any number of contestants having linear convex or concave cost functions and for any distribution of abilities 2 if the cost functions are linear or concave then no matter what the distribution of abilities is it is optimal for the designer to allocate the entire prize sum to a single first prize 3 we give a necessary and sufficient conditions ensuring that several prizes are optimal if contestants have a convex cost function

capital theory and the measurement of sustainable development an indicator of weak sustainability the measurement of sustainable development is not without considerable difficulties yet this should not detract from the positive advances that can be made in this direction in this paper we present one form that a weak sustainability indicator can take derived from a simple but intuitive savings rule it incorporates the idea that the level of overall capital stock should be non decreasing although subject to qualification at this stage some interesting results emerge from the application of the rule to 18 countries

investment tournaments when should a rational agent put all eggs in one basket we study investment tournaments a class of decision problems involving gradual allocation of investment among several alternatives whose values are subject to shocks the decision maker s payoff is determined by the final values of the alternatives an important example of such tournaments is the career choice problem since a person typically starts by investing in learning several professions we show that in many cases it is optimal for the decision maker to allocate all resources to the most promising alternative in each time period we also show that in promotion tournaments the workers optimally exert higher efforts at an early stage in order to capture a larger share of employer s investment such as mentoring

measuring sustainable development some empirical evidence for france from eight alternative indicators abstract this paper presents results from a time series analysis of eight measures of development and or sustainability for france the measures chosen are green national net product genuine savings ecological footprint indicator of sustainable economic welfare genuine progress indicator pollution sensitive human development indicator sustainable human development indicator and french dashboard on sustainable development a theoretical description of each index highlights their advantages and drawbacks underlining the fact that no indicator is perfect and no one can give an exhaustive view of sustainable development therefore the analysis of various indicators is necessary to evaluate sustainable development with accuracy empirical results of measures of well being show that french development was improving between 1990 and 2000 concerning sustainability indicators support different conclusions it seems that french development was weakly sustainable but unsustainable in the strong sense over the period examined

comparing augmented sustainability measures for scotland is there a mismatch we estimate and compare two empirical measures of the weak sustainability of an economy for the first time the change in augmented green net national product gnnp and the interest on augmented genuine savings gs yearly calculations are given for each measure for scotland during 1992 1999 augmentation means including using projections to 2020 changed production possibilities enabled by exogenous technical progress or changing oil prices the change in augmented gnnp and the interest on augmented gs are both always positive showing no sustainability problem for scotland then according to the assumptions underlying our weak sustainability calculations however the former greatly exceeds the latter even when macroeconomic fluctuations are taken into account this is a mismatch which poses an unresolved problem with the theory resolving it may require respecifying the utility functions used in mainstream growth theory

measuring sustainability a time series of alternative indicators for scotland this paper presents results from a time series analysis of seven alternative measures of sustainability for scotland the measures chosen are green net national product genuine savings ecological footprint environmental space net primary productivity the index of sustainable economic welfare and the genuine progress indicator these are all measures at the national or macro level we note arguments in the literature that no one single measure of sustainability is likely to be sufficient however very different messages concerning the sustainability of scotland over the period in question 1980 1993 emerge from these measures chosen we also argue that different indicators provide different insights for policy making

the concept of weak sustainability abstract this paper surveys the links between growth theory with exhaustible resources and the concept of weak sustainability it examines the underlying assumptions behind this concept and questions the usefulness of the weak sustainability index as an indicator of sustainable development

re evaluating okun s law why all recessions and recoveries are different abstract this paper explores the relationship between gdp growth the unemployment rate and employment growth using a structural dsge model and a data rich estimation approach i am able to estimate the coefficients and correlations between gdp growth and unemployment rate changes gdp growth and overall employment growth as well as gdp growth and employment growth by sector i find equivalent estimates when i compare the simulated model with realized data i then evaluate the effect different types of economic shocks have on these correlations and i find that investment and finance shocks have larger effects on employment growth and the unemployment rate when compared to productivity and other supply side shocks

executive compensation and tournament theory empirical tests on danish data this article adds to the empirical literature on tournament theory as a theory of executive compensation i test several propositions of tournament models on a rich data set containing information about 2 600 executives in 210 danish firms during a 4 year period i ask are pay differentials between job levels consistent with relative compensation is pay dispersion between levels higher in noisy environments is the dispersion affected by the number of tournament participants is average pay lower in firms with more compressed pay structures does wider pay dispersion enhance firm performance most of the predictions gain support in the data

natural resources national accounting and economic depreciation abstract the current value hamiltonian in an aggregate optimal growth problem with heterogeneous capital stocks including exhaustible renewable and environmental stocks is the nnp function routine substitutions reveal that the using up of natural resource stocks is representable as easy to interpret economic depreciation magnitudes we obtain true nnp inclusive of natural resource stock diminution implications for actual national accounting practices are also discussed

dynamic multidimensional assessment of sustainability at the macro level the case of austria abstract this paper explores the issue of sustainability at the macro scale employing multi criteria decision aid mcda methods the incommensurability of values and the essentially multi dimensional and dynamic nature of sustainability challenge the use of composite measurement indices this determined the choice of mcda methods austria was chosen as a case study due to the wide availability of data especially on indicators of strong sustainability the structure of the multi criteria problem comprised the evolution of different sustainability dimensions over time the process for selecting criteria included a critical assessment of institutional sustainability agendas un eu and austrian government and theoretical recommendations after an assessment of mcda methods the naiade method demonstrated the most suitable properties for sustainability assessment the application of this outranking approach was undertaken in three separate settings long term from 1960 to 2003 medium term 1970 1995 and short term 1995 2003 with varying numbers of criteria the response of results to the addition of evaluating criteria and periods was tested the degree of credibility for accepting preference relations was also employed for sensitivity analysis according to the results of long term and medium term assessments especially in the weak sustainability setting sustainable progress is taking place in austria in the short term in the stronger sustainability setting and especially as the number of criteria increases more incomparable periods appear and trends are less determined moreover it is shown how results crucially depend on the methodological choices this is one of the first applications of the multi criteria tools to the dynamic analysis of sustainability at the macro scale

rat race redux adverse selection in the determination of work hours in law firms this paper describes an organizational setting in which professional employees are required to work inefficiently long hours the focus of the authors investigation is large law firms the income sharing that characterizes legal partnerships creates incentives to promote associates who have a propensity to work very hard law firms use indicators of this propensity especially an associate s record of billable hours in promotion decisions reliance upon work hours as an indicator leads to a rat race equilibrium in which associates work too many hours the authors find evidence in support of this conclusion with data they collected from two large law firms copyright 1996 by american economic association

digging for golden carrots an analysis of research tournaments contracting for research is often infeasible because research inputs are unobservable and research outcomes cannot be verified by a court sponsoring a research tournament can resolve these problems a model is presented in which contestants compete to find the innovation of highest value to the tournament sponsor the winner receives a prespecified prize the tournament game has a unique subgame perfect equilibrium free entry is not optimal because equilibrium effort by each researcher decreases in the number of contestants an optimally designed research tournament balances the probability of overshooting the first best quality level against the probability of falling short copyright 1995 by american economic association
