more on moral hazard in organizations reply the paper by thomas hammond and gary miller is an insightful comment on the relevance of budget breaking incentive schemes to real world organizations they have made a valuable contribution in considering this line of research within a broader context nonetheless they have not established the invalidity of my theoretical arguments therefore my basic point still holds that is theoretically it is possible to show that a bonus penalty incentive scheme of the sort proposed by holmstrom is feasible despite the principal s incentive to cheat regardless all of this debate may beg the question since compensation arrangements observed in the real world are rarely of the bonus penalty type linear incentives are far more common and many compensation schemes do not appear to incorporate optimal incentives at this point we need more empirical research on the determinants of incentives in organizations in order to make further advances in this area a better understanding of the incentive mechanisms actually used in organizations is required

profitability and profit sharing claims that profit sharing is a purely distributive wealth confiscation scheme without incentive effects due to free rider problems are based on neglect of cooperation and interaction in the workforce when these activities are difficult to monitor directly group incentives such as profit sharing can increase efficiency and maintain a superior nashequilibrium with strictly individual optimization with simultaneous wls tobit estimates we find here strong effects of profit sharing and worker ownership shares on residual owners return on capital in medium sized metal working firms in west germany complementing earlier results on productivity

trading mechanisms and stock returns an empirical investigation this paper examines the effects of the mechanism by which securities are traded on their price behavior we compare the behavior of open to open and close to close returns on nyse stocks given the differences in execution methods applied in the opening and closing transactions opening returns are found to exhibit greater dispersion greater deviations from normality and a more negative and significant autocorrelation pattern than closing returns we study the effects of the bid ask spread and the price adjustment process on the estimated return variances and covariances and discuss the associated biases we conclude that the trading mechanism has a significant effect on stock price behavior

the entrepreneur s reward for self policing the collaboration among people is often subject to shirking the net gain from the collaboration depends on the contract governing it i argue that the entrepreneur assumes the role of the residual claimant because his actions are more costly to monitor than those of the factors with which he collaborates by offering fixed pay contracts to others and himself becoming residual claimant the entrepreneur curtails his incentive to gain at the expense of his partners and the net gain from the collaboration is then maximized costly monitoring applies to both labor and capital and thus the entrepreneur may supply both labor services and capital the entrepreneur s capital serves to guarantee the pay of the other factors

on some recent explanations of why capital hires labor conventional microeconomics contains no explanation of why capital hires labor and not the reverse in view of some surprisingly positive results in the theoretical analysis of worker run enterprise systems recent contributions to the theory of the firm have attempted to explain the dominance of capitalist production relations in efficiency terms the present paper critically reviews works in this area by alchian and demsetz 1972 williamson 1975 1980 and jensen and meckling 1979 and contends that a convincing efficiency argument for the general superiority of capital owners over workers control of enterprises still is lacking

the function of authority in transaction cost economics abstract this paper questions the transaction cost characterization of observed authority relations as efficient governance structures various inadequacies in the transaction cost account of work organization and the limits of firm size are traced to its neglect of the possibility that authority may be abused opportunistically this exemplifies a more general propensity in the transaction cost literature that of explaining economic organization in functionalist terms with little attention to the causal mechanisms through which efficient governance structures might actually arise three such mechanisms are considered but none is found to provide an adequate rationale for the imputation of efficiency to observed structures

employee ownership and internal governance abstract this paper is designed to counter oliver williamson s hypothetical peer group model of organization with a discussion of three prosperous populations of employee owned firms worked owned scavenger companies taxi cooperatives and professional partnerships such as the large law firm it will be shown here that these firms are formed endure and prevail over their competition for reasons that williamson more than anyone else has taught us to appreciate in particular this paper will argue that the metering problems and human asset considerations that are so prominently featured in williamson s work are crucial for understanding the success of these firms

expected revenue from open and sealed bid auctions in his preceding piece paul milgrom has neatly laid out many of the core results of the recent literature on the theory of competitive bidding my immediate goal here is to provide the simplest possible derivation of three basic revenue ranking theorems each of these compares the expected revenue obtained from open bidding as in the typical art auction with the expected revenue obtained when bids are sealed and the winner pays his bid the first of the ranking theorems is the revenue equivalence theorem which establishes conditions under which these two seemingly very different auctions generate the same expected revenue for the seller the other two theorems establish the effect of relaxing one of the key assumptions when buyers are risk averse the seller gains if buyers submit sealed bids and the winner pays his bid on the other hand if valuations of different buyers are positively correlated rather than unrelated the seller extracts more revenue in an open ascending bid auction in reducing these theorems to their basic elements my deeper goal is to provide the reader with a better intuitive understanding of the results

on the economic rationale for codetermination law abstract this paper develops a positive efficiency economic case for codetermination law resting on the correction of labor and capital market and organizational failures a legally mandated codetermination structure is shown to provide employee checks on several structural incentives for management opportunism codetermination is shown to offer advantages for technical efficiency skill development and knowledge generation through its protection of specific human capital investments financial markets cannot enforce codetermination due to a set of free rider problems

consolidation fragmentation and market performance this paper studies the impact of market consolidation or fragmentation on its performance examining four alternative models of exchange a consolidated clearing house fragmented clearing houses a monopoly dealer market and an interdealer market the effects of the market mechanism on the expected quantity traded the price variance faced by individual traders the quality of market price signals the expected gains from trade and the exchange implementation costs are studied

why capital suppliers usually hire workers what we know and what we need to know abstract a fundamental question for economics is why large firms in market economies usually assign control rights to capital suppliers rather than labor suppliers a diverse collection of answers can be found in the literature but unfortunately little theoretical consensus has emerged and few attempts have been made to resolve this issue through systematic empirical investigation this paper reviews a number of different hypotheses clustering around work incentives the financing of firms and collective choice we identify the strengths and weaknesses of each approach filling in theoretical gaps where necessary and conclude with some suggestions for empirical research

hierarchy vs partnership abstract simple organizations composed of operatives and one manager may be organized as a hierarchy with the manager appropriating all profits or as a partnership with say equal shares of profits conditions on profitability and the optimal span of control are analyzed next partnerships are considered and alternative incentives and distributions are compared when partners are free to choose their time inputs then a sufficiently high preference for leisure as against income will make a partnership more attractive even though it is less profitable

the dynamics of stock index and stock index futures returns in rational efficiently functioning markets the returns on stock index and stock index futures contracts should be perfectly contemporaneously correlated this study investigates the time series properties of 5 minute intraday returns of stock index and stock index futures contracts and finds that sp however the effect is not completely unidirectional with lagged stock index returns having a mild positive predictive impact on futures returns

the temporal price relationship between s p 500 futures and the s p 500 index this paper empirically examines the intraday price relationship between s p 500 futures and the s p 500 index using minute to minute data three stage least squares regression is used to estimate lead and lag relationships with estimates for expiration days of the s p 500 futures compared with estimates for days prior to expiration the results suggest that futures price movements consistently lead index movements by twenty to forty five minutes while movements in the index rarely affect futures beyond one minute

uniqueness of equilibrium in sealed high bid auctions abstract for the case of two buyers we show that equilibrium in the sealed high bid auction is unique when i buyers reservations prices are drawn independently from distributions with finite support and positive mass at the lower endpoint ii buyers have private values and iii buyers preferences are log supermodular for more than two buyers we obtain the same result under the additional assumptions that iv buyers with the same reservation price have the same preferences v buyers are risk neutral or risk averse with non increasing absolute risk aversion and vi the supports of the different buyers distributions of reservation prices have the same upper endpoint

a further analysis of the lead lag relationship between the cash market and stock index futures market the intraday lead lag relation between returns of the major market cash index and returns of the major market index futures and s p 500 futures is investigated empirical results show strong evidence that the futures leads the cash index and weak evidence that the cash index leads the futures the asymmetric lead lag relation holds between the futures and all component stocks including those that trade in almost every five minute interval evidence indicates that when more stocks move together market wide information the futures leads the cash index to a greater degree this suggests that the futures market is the main source of market wide information article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

a modified collective agriculture in rural growth with equity reconsidering the private unimodal solution abstract this paper identifies limitations of an agricultural structure of small private farms as a basis for rural growth with distributive equity and points out potential advantages of democratically managed collectives characterized by flexibility with respect to production scale group checks on inequality in land use and avoidance of the underemployment generating tendencies of large scale non collective agriculture after a critique of recent literature on scale economies and a discussion of stratification tendencies in private agriculture a model of democratic rural collectives incorporating features of chinese and tanzanian precedents is introduced and evaluated political feasibility is considered in a concluding discussion

measuring cash futures temporal effects in the uk using partial adjustment factors abstract the nature and extent of intertemporal adjustments across stock index futures and cash markets in the uk are investigated in terms of partial adjustment factors this approach affords the means of establishing both differential price movements in these markets and additionally providing a readily interpretable measure of the degree of such relative price movements analytic expressions are developed for jointly measuring the partial adjustment factors in cash and futures markets using a partial adjustment with noise model the measures are adjusted for non synchronous trading and asymptotic sampling variances derived adjustment factors are estimated using daily data over the period 1984 1992 with differencing intervals ranging from one to thirty days price adjustments were found to be fuller in futures markets particularly over shorter differencing intervals corrections for non synchronous effects in the cash market increased the magnitude of price adjustment as did the exclusion of data from the 1987 crash period

uniqueness of the equilibrium in first price auctions abstract if the value cumulative distribution functions are strictly log concave at the highest lower extremity of their supports a simple geometric argument establishes the uniqueness of the equilibrium of the first price auction in the asymmetric independent private values model

the nature of the agricultural firm abstract models explaining the choice between rent wage and share contracts in agriculture abstract from the large variations within the classes of rent share and owner managed forms of organization regarding the extent to which a specific form accommodates specialization between labor and management as a result modern explanations of agricultural organizations are misleadingly dependent on risk aversion or the assumption that landowners have an absolute advantage in production decisions viewing the agricultural firm as a constitution instead of as a nexus of contracts facilitates an agency explanation of alternative organizational forms and their amenability to specialization

seasonality estimation in thin markets the greater availability of daily data in the u s has led to a number of studies of the seasonality of daily stock index returns while the studies recognized the potential impacts of nontrading and price adjustment delays in general no formal analyses of such impacts were presented in this paper analytic results are presented for the articulation between these phenomena the implications of the analysis are discussed and shown to be consistent with a sample of u k index data a modified form of the negative weekend effect is found to be present in the u k data analyzed tests for the presence of seasonality in equity returns have been carried out by a number of authors at both the monthly and daily return levels at the monthly level rozeff and kinney 18 discovered evidence of seasonality in the u s while officer 15 detected the presence of seasonality in australian data fama 7 carried out some early work on u s daily data and more recent contributions have been made by cross 5 french 9 and gibbons and hess 10 while these studies recognized the presence of thin trading and its potential impacts upon the experimental results no formal analyses were presented in this paper we derive analytic results for the articulation between seasonality and nontrading effects section i the implications of this analysis are tested using a sample described in section ii of u k daily index data2 in section iii section iv discusses the implications of the results for capital market efficiency finally

transaction costs and partnerships the case of rock bands abstract this paper applies transaction cost economics to rock bands it develops the importance of asset specificity a number of phenomena in the field are shown to be explicable in terms of transactions costs

equilibrium in sealed high bid auctions there is a voluminous theoretical literature on sealed high bid auctions auctions in which bids are sealed and the high bidder pays his bid see for example vickrey 1961 myerson 1981 riley and samuelson 1981 milgrom and weber 1982 matthews 1983 maskin and riley 1984 holt 1980 cox smith and walker 1988 a critical property on which this literature relies is the existence of equilibrium in which buyers bidding strategies are monotonic in their types this enables the analyst to perform comparative statics as the distribution of types changes and to compare the welfare properties of the high bid auction with those of other auction institutions one case in which the existence of monotonic equilibrium is readily established is that in which buyers types are distributed smoothly independently and symmetrically in this case there exists a symmetric equilibrium one in which all bidders share the same bidding behaviour as a function of their valuations and this bid function is the solution to a first order differential equation

market behavior in a clearing house one of the most fundamental market mechanisms is the clearing house where orders are accumulated over time and the market is cleared periodically the issue addressed in this study is the statistical behavior of the market under this neutral mechanism in the framework of a tractable stochastic model which captures the underlying uncertainties and indivisibilities in the demand and supply schedules applying renewal theory we derive closed form results for the behavior of prices and quantities and pursue the implications of the possibility of no trade and the multiplicity of market clearing prices

some behavioral perspectives on the dominance of hierarchical over democratic forms of enterprise abstract this paper explores possible reasons why participatory modes of organization whole potentially viable and preferable to hierarchical modes for a large majority of workers may be dominated by the latter in capitalist market economies after exploring the developmental preconditions for the evolution of a mature participatory mode using a behavioral approach to organizations it is suggested that since the interest of those possessing scarce managerial skills may lie with hierarchical firms a participatory sector may be uncompetitive unless rights to enter labor contracts are redefined thus the analysis offers a partial explanation of the political nature of the demand for workplace democracy

hedging performance and basis risk in stock index futures in early 1982 trading began at three different exchanges in futures contracts based on stock indexes stock index futures were an immediate success and quickly led to a proliferation of new futures and options markets tied to various indexes one reason for this success was that index futures greatly extended the range of investment and risk management strategies available to investors by offering them for the first time the possibility of unbundling the market and nonmarket components of risk and return in their portfolios many portfolio management and other hedging applications in investment banking and security trading have been described elsewhere1 ranging from use by a passive fund manager to reduce risk over a long time horizon to use by an underwriter to hedge the market risk exposure in a stock offering for one or two days in considering the potential applications of index futures it is clear that in nearly every case a cross hedge is involved that is the stock position that is being hedged is different from the underlying portfolio for the index contract 2 this means that return and risk for an index futures hedge will depend upon the behavior of the basis i e the difference between the futures price and the cash price hedging a position in stock will necessarily expose it to some measure of basis risk risk that the change in the futures price over time will not track exactly the value of the cash position basis risk can arise from a number of different sources and is a more significant problem for stock index contracts than for other financial futures like treasury bills and bonds 3 the most apparent cause of basis risk is the nonmarket component of return on the cash stock position since the index contract is tied to the behavior of an underlying stock market index nonmarket risk cannot be hedged this is the essential problem of a cross hedge however basis risk can be present even when the hedge involves a position in the index portfolio itself and there is no nonmarket risk for one thing returns to the index portfolio include dividends while the index and the index future only track the capital value of the portfolio any risk associated with dividends on the portfolio will become basis risk in a hedged position still dividends are fairly low and also quite stable so this may not be a terribly important shortcoming

a simple measure of price adjustment coefficients one measure of market efficiency is the speed with which prices adjust to new information we develop a simple approach to estimating these price adjustment coefficients by using the information in return processes this approach is used to estimate the price adjustment coefficients for firms listed on the nyse and the amex as well as for over the counter stocks we find evidence of a lagged adjustment to new information in shorter return intervals for firms in all market value classes and some support for the proposition that prices adjust much more slowly and with more noise for smaller firms

index futures arbitrage and the behavior of stock index futures prices this article examines intraday transaction datafor s p 500 stock indexfutures prices and the intraday quotes for the underlying index the data indicate that thefutures price changes are uncorrelated and that the variability of these price changes exceeds the variability ofprice changes in the s p 500 index this excess variability of the futures over the index remains even after controlling for the nonsynchronous prices in the index quotes which induces autocorrelation in the index changes we advance and examine empirically two hypotheses regarding the difference between the futures price and its theoretical value that this mispricing increases on average with maturity and that it is path dependent evidence supporting these hypotheses is presented

on the incidence of profit and equity sharing theory and an application to the high tech sector abstract profit and equity sharing benefit some firms through improvements in innovation production quality retention of key employees and specific human capital formation the analysis predicts high share contract incidence in the high tech sector a hypothesis supported by survey data collected from small and large high tech firms however externalities associated with this sector s market entry mechanism imply that the optimal level of profit and equity sharing may not have been achieved

is capitalism necessary a critique of the neoclassical economics of organization abstract in recent years neoclassical economists have offered a theory of the capitalist firm which implies that the corporation is uniquely adapted to the complexities of the modern industrial economy hence it is argued capitalism is necessary to efficiency this paper designs a non capitalist firm that satisfies all the criteria for efficiency unumerated by the neoclassical institutional economists the design suggests that by separating capitalism from the capital market advocates of non capitalist market systems need not discard the capital market as an instrument of economic control

the ontology of economic power in capitalism mainstream economics and marx mainstream economics conceives power to be incompatible with perfect competition this conception i argue derives from its deductivist method and the empirical realist ontology that it presupposes following marx i show that capitalism constantly reproduces asymmetrical constraints on classes of individuals independent of the market form my ontological argument is rooted in the philosophy of critical realism my conclusion is that the dichotomy power competition is ontologically untenable if capitalist relations necessarily involve power it is not simply because neoclassical competition does not exist in reality as radical mainstream economists suggest but rather because capitalism altogether is a system of power

taxes and the pricing of stock index futures stock index futures prices are generally below the level predicted by simple arbitrage models this paper suggests that the discrepancy between the actual and predicted prices is caused by taxes capital gains and losses are not taxed until they are realized as constantinides demonstrates in a recent paper this gives stockholders a valuable timing option if the stock price drops the investor can pass part of the loss on to the government by selling the stock on the other hand if the stock price rises the investor can postpone the tax by not realizing the gain since this option is not available to stock index futures traders the futures prices will be lower than standard no tax models predict on 24 february 1982 the kansas city board of trade began trading futures contracts on the value line average stock index during the next two months both the chicago mercantile exchange and the new york futures exchange also initiated trading in stock index futures although these contracts are actively traded their prices have puzzled both practitioners and academics the observed

mean reversion of standard poor s 500 index basis changes arbitrage induced or statistical illusion mean reversion in stock index basis changes has been presumed to be driven by the trading activity of stock index arbitragers we propose here instead that the observed negative autocorrelation in basis changes is mainly a statistical illusion arising because many stocks in the index portfolio trade infrequently even without formal arbitrage reported basis changes would appear negatively autocorrelated as lagging stocks eventually trade and get updated the implications of this study go beyond index arbitrage however our analysis suggests that spurious elements may creep in whenever the price change or return series of two securities or portfolios of securities are differenced mean reversion in stock index basis changes has been amply documented mackinlay and ramaswamy 1988 find significant negative first order autocorrelation in normalized intraday basis changes of the s p 500 index futures traded on the chicago mercantile exchange cme yadav and pope 1990 find similar behavior using financial times stock exchange ftse 100 index futures data from the london international financial futures exchange liffe as does lim 1990 using nikkei 225 index futures from the singapore international monetary exchange simex the trading activity of stock index arbitragers has been presumed to be driving this elastic realignment of stock index and index futures prices when the basis widens beyond its theoretical level arbitragers simultaneously sell index futures and buy the index portfolio pulling the difference between the futures and index

debt ceiling and fiscal sustainability in brazil a quantile autoregression approach abstract in this paper we investigate fiscal sustainability by using a quantile autoregression qar model we propose a novel methodology to separate periods of nonstationarity from stationary ones allowing us to identify various trajectories of public debt that are compatible with fiscal sustainability we use such trajectories to construct a debt ceiling that is the largest value of public debt that does not jeopardize long run fiscal sustainability we make an out of sample forecast of such a ceiling and show how it could be used by policy makers interested in keeping the public debt on a sustainable path we illustrate the applicability of our results using brazilian data

the trading decision and market clearing under transaction price uncertainty this paper models an individual s trading decision given 1 his her demand function to hold shares of an asset 2 his her expectation on what the market clearing price will be and 3 the design of the market which determines how orders will be translated into trades the particular market design we consider is the batched trading periodic call regime assuming investors are distributed according to their propensities to hold shares we model the aggregation of orders to obtain market clearing values of price and volume and to show the way in which with trading friction these solutions differ from pareto efficient values the importance of this analysis for various issues concerning market design is noted when markets are not frictionless and transaction prices are uncertain the act of trading requires analysis this paper models an individual s trading decision in secondary financial asset markets in so doing we study the order flow as an endogenous part of the system we show how given an underlying demand curve the trader will choose an optimal price quantity order to transmit to the market and we model the aggregation of orders to obtain market clearing values for price and volume these models are used to show the way in which the prices and trading volume established on the market will in general differ from their pareto efficient values much of the microstructure literature that studies the behavior of transaction prices in a nonfrictionless market has assumed that orders are generated by some exogenously given stochastic process this has been true for instance in the

first price auction symmetric equilibria with a general distribution abstract in this paper i obtain the mixed strategy symmetric equilibria of the independent private values first price auction for any distribution of valuations the equilibrium strategy is a pure strategy at the continuity points of the distribution and bids a mixed strategy at the discontinuity points of the distribution

random competitive exchange price distributions and gains from trade abstract this paper studies the behavior of a competitive exchange under uncertain preferences and random indivisible endowments we obtain explicit closed form results for the price distribution and expected gains from trade both for case where the market is thin and the number of traders is low and for the asymptotic case where the number of traders tends to infinity we demonstrate that increasing the number of traders reduces price variability and increases the expected gains from trade and that increasing the variability of traders reservation prices increases price variability as well as the expected asymptotic gains from trade
