ipo underpricing and flotation methods in taiwan a stochastic frontier approach adopting stochastic frontier analysis this article studies the pricing model and underpricing phenomenon of the initial public offerings ipos in taiwan and further elucidates the potential impact of offering mechanisms on underpricing the sampling period is from 1996 to 2003 in which 647 ipos are selected empirical results suggest that issuing firms with greater earning potentials less risk or less asymmetric information have lower underpricing furthermore the variables included to explain underpricing are mostly significant especially the proxy variable for flotation method observed mean ipo underpricing is 20 59 in the sample period compared to 17 12 for the subgroup using the auction method this statistically significant difference implies that the introduction of the auction method can help reduce ipo underpricing

improving prediction market forecasts by detecting and correcting possible over reaction to price movements abstract we examine the impact of price trends on the accuracy of forecasts from prediction markets in particular we study an electronic betting exchange market and construct independent variables from market price odds time series from 6058 individual markets a dataset consisting of over 8 4 million price points using a conditional logit model we find that a systematic relationship exists between trends in odds and the accuracy of odds implied event probabilities the relationship is consistent with participants over reacting to price movements in particular in different time segments of the market increasing and decreasing odds lead respectively to under and over estimation of odds implied probabilities we develop a methodology to detect and correct the erroneous forecasts associated with these trends in odds in order to considerably improve the quality of forecasts generated in prediction markets

initial public offer underpricing the issuer s view a note many studies for example bear and curley 1 beatty and ritter 2 block and stanley 3 ibbotson 4 ibbotson and jaffe 5 logue 6 mcdonald and fisher 7 neuberger and la chapelle 8 reilly 9 and ritter 10 11 show that initial public offers ipos are underpriced on average when offered to the public all these studies focus on the difference between the offer price and the observed market price which is the return earned by new investors only a few studies refer to issuer oriented measures of underpricing and each also uses the observed market price as the benchmark bear and curley 1 for example based the efficiency of new issue pricing on the relationship between the offering price and the initial secondary market price ibbotson 4 used the market price to describe various explanations for underpricing from the issuer or underwriter s perspective ritter 11 developed a detailed pricing analysis for the choice between firm commitment and best efforts underwriting contracts but the comparison price remained the post issue market price a similar reliance upon the observed market price in measuring ipo underpricing is found in corporate finance textbooks this note demonstrates that traditional investor oriented measures of underpricing may mislead issuers ipos do not simply have a cost with the opposite sign of the investors return rather underpriced new shares create a dilutive effect that may make their real cost or wealth transfer much different section i develops an alternative measure of underpricing that is issuer oriented and documents the difference between the two measures using ipos issued in singapore from 1978 1985 section ii analyzes the increased costs for issuers of underpricing ipos using the new measure of underpricing

the effects of inflation and time value of money on an economic order quantity model with a random product life cycle abstract for several decades the economic order quantity eoq model and its variations have received much attention from researchers recently there has been an investigation into an eoq model incorporating a random product life cycle and the concept of time value of money this paper extends the previous research in several areas first we investigate the impact of inflation on the choice of replenishment quantities second the unit cost which has been inadvertently omitted in the previous research is included in the objective function to properly model the problem third we consider the normal distribution as a product life cycle in addition to the exponential distribution fourth we develop a simulation model which can be used for any probability distribution

investments in modern production technology and the cash flow oriented epq model in this study we analyze investments in setup and production processes in the context of the traditional inventory problem the comparison of the results of a cash flow and a cost oriented model suggests the use of the net present value as a decision criterion the analysis shows that an additional investment which reduces setup cost decreases the optimal capital investment necessary to reduce production cost and vice versa an investment which increases the production rate however may increase or decrease the capital expenditure of an investment in the setup process

the discounted r q inventory model the shrewd accountant s heuristic abstract the discounted continuous review r q inventory model with continuous and stochastic demand is investigated new optimality conditions are derived clarifying the difference to the average cost case also graphically supported by depreciation theory applied to the value of a setup the results suggest an insightful and very precise approximation the shrewd accountant s heuristic based on a new average cost model it deepens and extends the work of hadley 1964 three examples are worked out in detail and the model is generalized to poisson demand and to stochastic lead times

a century of evolution from harris s basic lot size model survey and research agenda abstract determining the economic lot size has always represented one of the most important issues in production planning this problem has long attracted the attention of researchers and several models have been developed to meet requirements at minimum cost in this paper we explore and discuss the evolution of these models during one hundred years of history starting from the basic model developed by harris in 1913 up to today following harris s work a number of researchers have devised extensions that incorporate additional considerations the evolution of eoq theory strongly reflects the development of industrial systems over the past century here we outline all the research areas faced in the past by conducting a holistic analysis of 219 selected journal papers and trying to give a comprehensive view of past work on the eoq problem finally a new research agenda is proposed and discussed

economies of diversification in the banking industry abstract this paper defines a new measure economies of diversification to examine the cost effect of product line expansion this measure is a special case of expansion path subadditivity and contains economies of scope as a special case a nonparametric frontier technique which isolates the effects of inefficiency and scale is used to measure economies of diversification applied to a set of 468 u s depository institutions operating in 1984 we find slight diseconomies of diversification diseconomies of diversification and inefficiency due to the overutilization of resources are found to be more important determinants of bank costs than is the failure to operate at optimal scale

parimutuel wagering and video gaming a racetrack portfolio parimutuel wagering has been declining for several decades due in part to increased competition from state lotteries and casino gaming in recent years an attempt has been made to integrate video lottery terminal vlt gaming into a parimutuel racetrack s product portfolio daily data are used to develop product demand equations for parimutuel horse race wagering and video lottery gaming at a throughbred racetrack it is found that introduction of vlts into the product mix results in decreased parimutuel wagering and revenues however the additional revenue generated from the vlts is found to more than offset the decline in parimutuel revenue and the increased expense associated with the vlts given that a sufficient number of terminals are made available when revenue from the combined parimutuel and vlt gaming product increases if the respective shares of the vlt revenue distributed to the racetrack to the horsemen who race horses at the racetrack and to the government are the same as their distri

an analysis of exotic wagers in a parimutuel setting in us horse racing there is increasing emphasis placed on the creation of exotic wagers those bets beyond the standard win place and show bets on multiple races that typically do not result in a winner for several days are of particular interest to the industry the growing carryover pool helps attract people to the racetrack in a way similar to a growing carryover in the lottery attracts more people to participate this article examines several multiple race bets and provides a framework for their comparative analysis the results of the analysis will help racetrack management decide if a proposed bet is appropriate for their particular track this analysis shows a tradeoff between the difficulty of winning the bet versus the amount of the ultimate payoff if a bet is too easy to win then the carryover pool will never reach an attractive level if the bet is too difficult to win then the bettors will lose interest before the carryover pool is able to grow sufficiently large the amount of money wa

bank credit rates across the business cycle evidence from a french cooperative contracts database abstract financial theory indicates that bank firm relationships can induce a hold up problem resulting in higher interest rates yet only weak empirical confirmation of this result exists moreover the potential influence of the business cycle on the bank firm relationship still requires empirical consideration with a unique contracts data set collected from a french cooperative bank between 1996 and 2009 this study shows that the effects of bank firm relationships on the credit rate depend on economic conditions and that the hold up problem is at play only during economic recessions

economic order quantity models for ameliorating deteriorating items under inflation and time discounting the items that incur a gradual loss in quality or quantity over time while in inventory are usually called deteriorating items in reality there are some items whose value or utility or quantity increase with time and those items can be termed as ameliorating items in this paper an effort has been made to incorporate these two opposite physical characteristics of stored items into inventory model we develop models for ameliorating deteriorating items with time varying demand pattern over a finite planning horizon taking into account the effects of inflation and time value of money optimal solutions of the proposed models are derived and the effects of amelioration deterioration on the inventory replenishment policies are studied with the help of numerical examples

holding costs under push or pull conditions the impact of the anchor point holding costs are traditionally determined from the investment in physical stock during a cycle an alternative approach instead derives holding costs from net present value npv functions it is known that applying both frameworks to the same system can lead to different holding cost valuations but little explanation has been offered by introducing the anchor point in a model this paper shows for four different systems that traditional holding cost models implicitly assume pull conditions while current npv approaches model push conditions this explains in part the differences between the methods it is shown that the anchor point concept allows the construction of npv models under pull conditions giving results in better correspondence with traditional models the traditional framework is restricted to pull conditions and important considerations could be easily overlooked leading to wrong valuations of holding costs npv seems superior as such considerations are automatically incorporated the application to multi echelon inventory systems provides interesting insights on the roles of echelon stocks and lead times and offers potential for future research

a note on savings and loan ownership structure and expense preference a re examination this study extends the work of akella and greenbaum journal of banking finance 12 1988 419 through the use of a much larger nationwide sample of us saving and loan associations and supports their original finding of significant expense preference behavior in mutual savings and loans during their original study period 1979 80 this study also provides evidence that over the time period of substantial deregulation and changes in the competitive environment in the us financial services industry expense preference behavior for savings and loans decreased the results are consistent with the idea that the removal of barriers that restrict competition should improve managerial efficiency in firms that survive 2003 elsevier b v all rights reserved

the structure of ownership and the theory of the firm the separation of ownership from control produces a condition where the interests of owner and of ultimate manager may and often do diverge and where many of the checks which formerly operated to limit the use of power disappear in creating these new relationships the quasi public corporation may fairly be said to work a revolution it has divided ownership into nominal ownership and the power formerly joined to it thereby the corporation has changed the nature of profit seeking enterprise 1

selling to biased believers strategies of online lottery ticket vendors i introduction do sellers in the marketplace take advantage of the belief biases of their consumers models of markets typically assume that sellers are profit maximizing consumers are utility maximizing and both sides of the market have accurate unbiased beliefs however an increasing collection of evidence shows that the presence of cognitive and strategic heterogeneity can account for many stylized facts in the marketplace which appear puzzling when confined to the framework of classical models we examine the behavior of sellers in a popular online market which provides an unusual opportunity to identify seller exploitation of biased beliefs held by buyers the chinese collective lottery betting market in this market shares of ticket portfolios for china s national lottery are sold commissions are charged by the sellers and the success rates of sellers are made public as in most state run lotteries success is completely random with known probabilities that are independent of previous outcomes these objective probabilities allow us to cleanly detect deviations from rational beliefs among buyers and assess the corresponding responses by sellers in the market to these demand shocks of buyers we find evidence that sellers cater to the biased beliefs of lottery ticket buyers by tailoring certain features of their portfolio product specifically collective lottery portfolio sellers adjust their sales strategies in response to demand fluctuations that are driven by buyers biased beliefs about the correlation of past and future lottery outcomes lottery ticket buyers tend to purchase tickets with numbers which have not recently won in accordance with previous evidence of the gambler s fallacy in lottery sales clotfelter and cook 1993 terrell 1994 ticket buyers also tend to purchase tickets from those ticket sellers who have recently experienced an exogenous increase in their win rates in accordance with previous evidence of the hot hand fallacy croson and sundali 2005 guryan and kearney 2008 1 we find combined evidence that lottery portfolio sellers take advantage of buyers belief in the hot hand fallacy in the following ways 1 directly following a previous win in their portfolio sellers increase their commission rate charged to the buyers to be collected as a percentage of the lottery winnings sellers are thus able to collect more commission money from the buyers conditional on winning 2 sellers offer portfolios of larger value and more ticket coverage directly following a large win in their portfolio using this strategy sellers increase their chances of holding a winning ticket in the current round as well as being able to collect more commission money conditional on winning 3 sellers self invest less in their own portfolios after a large win when their popularity among buyers in the market is high by purchasing a lower share of their portfolios on their own sellers are able to obtain a larger expected return without investing their personal money we also find some evidence consistent with lottery ticket sellers adapting to buyers belief in the gambler s fallacy first sellers generally tend to offer lottery number portfolios which are numerically dissimilar to recent winning tickets thus appealing to buyers with gambler s fallacy beliefs although the more numerically dissimilar the portfolio is to the previous winning ticket the less the seller himself invests in it sellers who have proposed very similar numbers compared to the previous winning ticket on the other hand self invest more thus entering the lottery with higher expected returns under the pari mutuel prize structure this self investment pattern is not consistent with the alternative story that sellers themselves subscribe equally to the gambler s fallacy compared to buyers our paper is unique to the existing evidence in this area in that we are the first to our knowledge to study sellers responses to consumers probabilistic belief biases specifically the gambler s fallacy and hot hand fallacy

what drives deregulation economics and politics of the relaxation of bank branching restrictions this paper investigates private interest public interest and political institutional theories of regulatory change to analyze state level deregulation of bank branching restrictions using a hazard model we find that interest group factors related to the relative strength of potential winners large banks and small bank dependent firms and losers small banks and the rival insurance firms can explain the timing of branching deregulation across states during the last quarter century the same factors also explain congressional voting on interstate branching deregulation while we find some support for each theory the private interest approach provides the most compelling overall explanation of our results

determining optimal lot size for a two warehouse system with deterioration and shortages using net present value abstract in this paper we develop a deterministic inventory model for deteriorating items with two warehouses by minimizing the net present value of the total cost deterioration rates of items in the two warehouses may be different in addition we allow for shortages and complete backlogging we then prove that the optimal replenishment policy not only exists but also is unique under some condition further the result reveals that the reorder interval based on the average total cost if it exists must be longer than that derived using net present value finally we use yang s h l yang european journal of operational research 157 2004 344 356 numerical example to illustrate the model and conclude the paper with suggestions for possible future research

the demand for parimutuel horse race wagering and attendance there has been a long history of patron participation in parimutuel horse race wagering and attendance which are major recreational products in consumer budgets in this paper the demand for parimutuel horse race wagering and attendance has been specified and estimated for both thoroughbred and standardbred racetracks in a multistate market area the data are annual over the period 1960 1987 it is found that demand is price elastic in every case racing quality personal income the number of racing days competition from a state lottery and from professional sports baseball basketball football are all significant determinants of these demands both attendance and wagering are found to increase with an increase in racing quality however it seems that the new patrons attracted by quality racing tend to wager less than those who attend regularly the presence of a state lottery is found to have resulted in a substantial loss in attendance as well as in wagering at each of the racetracks this i

replenishment and pricing policy for deteriorating items taking into account the time value of money abstract a deteriorating inventory model taking into account the time value of money is developed for a deterministic inventory system with price dependent demand this study applies the discounted cash flows dcf approach for problem analysis a heuristic approach is presented to derive the near optimal replenishment and pricing policy that tries to maximize the total net present value profit a numerical example is implemented to illustrate the theory

growth security investment strategy for long and short runs it is well known that the investment policy maximizing the expected logarithm of wealth each period is a long run optimal capital growth criterion however the growth optimal strategy entails a considerable risk of losing a substantial portion of wealth for the investment in the short run this paper extends the long run capital growth criterion to a multiperiod investment policy which maximizes the capital growth and at the same time achieves a given probability of maintaining an accumulated risk free return over any finite investment horizon

productive efficiency performance of minority and nonminority owned banks a nonparametric approach abstract this study examines the efficiency performance of the minority owned banks mobs as multiproduct firms relative to that of the nonminority banks nmobs using a highly flexible nonparametric approach since mobs and nmobs employ distinct technologies the efficiency indices for the two groups are derived relative to their respective group specific frontiers and are contrasted to shed light on the ownership efficiency relationship the mob sample is then disaggregated and the intra group efficiency differentials are investigated the findings support the hypothesis that abstracting the regional regulatory size and maturity characteristics of banks efficiency differentials between mobs and nmobs are statistically insignificant

inside information in a betting market inside information concerning a risky asset is presumed to be beneficial to its holder measurement of the impact and benefit of inside information is difficult because its use for financial gain is often illegal ideally one would like to investigate and compare two mutually isolated groups one with and the other without access to inside information the australian horse betting market offers such an opportunity it is found that even exposure to second hand inside information effects a change in behavior a rise in payoffs and adds power and significance to the prediction of race results copyright 1995 by royal economic society

exotic betting opportunities pricing policies and the demand for parimutuel horse race wagering parimutuel horse race wagering has been declining steadily for the past several decades this has resulted in lower revenues to state governments recetracks adn horseman to retard or reverse this trend attempts have been made to implement a number of pricing and marketing strategies among these has been the introduction of a variety of exotic wagering opportunities over the years the number and type of exotic wagers offered has been increased furthermore the prices of both straight and exotic wagers have been increased and in addition the price of exotic wagers has generally been set at a higher rate than that for straight wagers the paper examines the effectiveness of these policies

transportation costs and product demand wagering on parimutuel horse racing parimutuel horse race wagering is in many respects like any other economic good but it differs in one important way from a vast majority of them given the present market arrangement this good cannot be transported to the consumer instead the consumer must travel to the production site where the good is consumed as it is produced thus transportation costs must play a crucial role in the demand decision for horse race wagering the consumers incur not only out of pocket expenses for travelling but also the cost of the time required to travel to and to consume the product moreover consumers incur differential costs in obtaining the same product because of their locational differences wagering demands are theorized to be the consequence of the choice of utility maximizing consumers which incorporates this special characteristic of the product models for parimutuel horse race wagering are then estimated both for thoroughbred and for harness horse racing in the state of new jersey it is found that bot

effects of legislation events on us gaming stock returns and market turnings abstract the deregulation of casino gaming has becomea new trend across the us since the beginning of this decade but from the mid 1990s on the voice of tightened regulation is lifted up by the public while the cyber casino online gambling business is also developing its own customer base this study examines various federal and state legislation events regarding casino gaming regulation and deregulation and finds that the announcement effects on stock portfolio returns vary across different types of gaming companies on average gaming equipment suppliers and small casino operators are found to react to legislation events more significantly compared with those large casino firms furthermore since the casino gaming business is believed to be highly sensitive to the economic upturns and downturns this paper also investigates the impacts on the risk adjusted return alpha and the systematic risk beta of gaming stocks across bull up and bear down market situations the results indicate that between july 1993 and december 1997 gaming stocks on average yield a significantly lower return and a significantly greater systematic risk against the us stock market after changes in stock market conditions are controlled the systematic risk is still considerably above the market average but the excess return turns out insignificant

the degree of inefficiency in the football betting market statistical tests abstract this paper tests the hypothesis that the football betting market is efficient our statistical tests are stronger than those in previous studies and we examine both nfl and college data over a sample period of fifteen years our statistical tests detect two specific biases in the nfl market and an unspecified bias in the college market we examine the year to year consistency and magnitudes of the biases and find that the nfl bias against home teams has been nearly eliminated while the bias against underdogs has increased profitable exploitation of the biases depends upon transaction costs

cumulative staircase considerations for dynamic lotsizing when backlogging is allowed abstract the dynamic lotsizing problem concerns the determination of optimal batch quantities when given required amounts appear at discrete points in time the standard formulation assumes that no shortages are allowed and that replenishments are made instantaneously for the case when no shortage is allowed previously it has been demonstrated that the inner corner condition for an optimal production plan in continuous time reduces the number of possible replenishment times to a finite set of given points at which either a replenishment is made or not the problem is thus turned into choosing from a set of zero one decisions with 2 n 1 alternatives of which at least one solution must be optimal where n is the number of requirement events recently the instantaneous replenishment assumption has been replaced by allowing for a finite production rate which turned the inner corner condition into a condition of tangency between the cumulative demand staircase and cumulative production in this paper we investigate relationships between optimal cumulative production and cumulative demand when backlogging is permitted the production rate is assumed constant and cumulative production will then be a set of consecutive ramps cumulative demand is a given staircase function the net present value npv principle is applied assuming a fixed setup cost for each ramp a unit production cost for each item produced and a unit revenue for each item sold at the time it is delivered among other results it is shown that optimal cumulative production necessarily intersects the demand staircase instead of having 2 n 1 production staircases as candidates for optimality there are 2 n 1 production structures as candidates these are made up of sequences of batches of which the set of batches may be optimised individually also is shown that the npv of each batch has a unique timing maximum and behaves initially in a concave way and ends as convex results for the average cost approach are obtained from a zeroth first order approximation of the objective function npv

searching for positive returns at the track a multinomial logic model for handicapping horse races this paper investigates fundamental investment strategies to detect and exploit the public s systematic errors in horse race wager markets a handicapping model is developed and applied to win betting in the pari mutuel system a multinomial logit model of the horse racing process is posited and estimated on a data base of 200 races a recently developed procedure for exploiting the information content of rank ordered choice sets is employed to obtain more efficient parameter estimates the variables in this discrete choice probability model include horse and jockey characteristics plus several race specific features hold out sampling procedures are employed to evaluate wagering strategies a wagering strategy that involves unobtrusive bets with a side constraint eliminating long shot betting appears to offer the promise of positive expected returns even in the presence of the typically large track take encountered at thoroughbred racing events

efficiency of the market for racetrack betting many racetrack bettors have systems since the track is a market similar in many ways to the stock market one would expect that the basic strategies would be either fundamental or technical in nature fundamental strategies utilize past data available from racing forms special sources etc to handicap races the investor then wagers on one or more horses whose probability of winning exceeds that determined by the odds by an amount sufficient to overcome the track take technical systems require less information and only utilize current betting data they attempt to find inefficiencies in the market and bet on such overlays when they have positive expected value previous studies and our data confirm that for win bets these inefficiencies which exist for underbet favorites and overbet longshots are not sufficiently great to result in positive profits this paper describes a technical system for place and show betting for which it appears to be possible to make substantial positive profits and thus to demonstrate market inefficiency in a weak form sense estimated theoretical probabilities of all possible finishes are compared with the actual amounts bet to determine profitable betting situations since the amount bet influences the odds and theory suggests that to maximize long run growth a logarithmic utility function is appropriate the resulting model is a nonlinear program side calculations generally reduce the number of possible bets in any one race to three or less hence the actual optimization is quite simple the system was tested on data from santa anita and exhibition park using exact and approximate solutions that make the system operational at the track given the limited time available for placing bets and found to produce substantial positive profits a model is developed to demonstrate that the profits are not due to chance but rather to proper identification of market inefficiencies

signalling and the valuation of unseasoned new issues revisited this paper provides further empirical evidence on the relation between entrepreneurial ownership retention and the initial value of unseasoned common shares a canadian data set is employed to estimate the various empirical specifications used in previous studies and to examine additional variables suggested by recent developments in the theoretical literature the estimation is carried out using a more general procedure to correct for heteroskedasticity in contrast to previous findings the entrepreneurial ownership reten tion signal does not possess statistical significance in any ofthe models examined

testing for deliberate underpricing in the ipo premarket a stochastic frontier approach we re evaluate the ipo underpricing phenomenon using the stochastic frontier methodology the advantage of the stochastic frontier is that it can be used to measure the level of deliberate underpricing in the premarket without using after market information this is accomplished through the estimation of a systematic one sided error term that measures inefficiency or the difference between the maximum predicted offer price and the actual offer price data for the analysis are comprised of 1 035 ipos of common stock issued by firm commitment between 1975 and 1984 ipos appear to be deliberately underpriced in the premarket in both hot market and nonhot market periods moreover the determinants of the maximum ipo price have different effects in the two time periods article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

savings and loan ownership structure and expense preference abstract this note demonstrates that the conclusion of the akella and greenbaum 1988 study that managers of mutual s ls exhibit more expense preference behavior than managers of stockholder owned s ls is premature it is shown that in operationalizing their theoretical model a g introduce an endogenous variable in their correction for homogeneity invalidating their results the only firm conclusion which can be drawn from their results is that a higher proportion of assets of mutual s ls is invested in loans while a higher proportion of liabilities are sourced from deposits than is the case for stockholder owned s ls

note on a quantity discount pricing model to increase vendor profits monahan monahan james p 1984 a quantity discount pricing model to increase vendor profits management sci 30 june 720 726 develops a model for establishing an optimal quantity discount schedule from a vendor s viewpoint in this note we show that this model is limited to the case where the vendor buys from another supplier incorporating vendor s inventory carrying costs we develop a generalized version of monahan s model and demonstrate its equivalence with the joint economic lot size approach suggested by banerjee banerjee avijit 1986 a joint economic lot size model for purchaser and vendor decision sci 17 summer 292 311

variable risk preferences and adaptive aspirations abstract observations of human decision making indicate that risk preferences depend on the values of possible outcomes relative to levels of aspiration a model of such variable risk preference is specified it suggests that some risk averse behavior may result from a human tendency to focus on targets and from the adaptation of those targets to experience rather than from a fixed trait of risk aversion in addition the model shows how risk preferences varying around adaptive aspirations produce both a greater long run likelihood of survival and a higher average return for survivors than do fixed risk preferences

arbitrage strategies for cross track betting on major horse races cross track betting permits bettors to place their local tracks on a race being run at another track since each track operates a separate betting pool the odds can vary across the tracks the data suggest that the odds vary and they often vary dramatically allowing arbitrage opportunities this article employs a risk free arbitrage model to demonstrate the cross track inefficiency and recommends an optimal capital growth model for exploiting it a simple method is proposed for a single bettor at a single cross track the results indicate that these methods would have worked well in practice on a number of recent triple crown races copyright 1990 by the university of chicago

capital income taxation and risk spreading with adverse selection domar and musgrave 1944 showed that taxing the return from risky investments may encourage risk taking the effect has come under attack as being one of partial analysis that would disappear in general equilibrium this paper shows that the contrary is true if capital markets suffer from adverse selection asymmetric information induces investors to bear risk that could be spread in the capital market the tendency to such behaviour may be increased by a tax on risky capital income in that case social risk spreading decreases while the opposite effect would hold if general equilibrium repercussions were ignored imposition du revenu de capital et repartition des risques quand il y a selection adverse domar et musgrave 1944 ont montre que l imposition des rendements sur les investisse ments risques pouvait encourager a courir plus de risque ce resultat a ete attaque comme resultat emergeant d une analyse d equilibre partiel et devant disparaitre en equilibre general

marginal risk aversion and preferences in a betting market an individual s behavioural attitudes toward variance and non symmetry in the payoff distributions of pari mutuel gambles are empirically examined using the von neumann morgenstern expected utility of wealth paradigm preferences over payoff distributions for a representative bettor are estimated from observed payoffs at a greyhound racetrack the results indicate that the representative bettor exhibits increasing absolute risk aversion and given that the representative bettor is locally non satiated with regard to wealth exhibits preference for variance and aversion to positive skewness in the payoff distributions of the gambles examined

coordination and profit sharing between a manufacturer and a buyer with target profit under credit option several studies have focused on buyer vendor coordination through quantity discount credit option mechanism but few quantitative models and investigations are available that have explored the mechanism for transfer of surplus generated due to coordination in this paper we develop a coordination mechanism through credit option such that both the parties can divide the surplus equitably after satisfying their own profit targets two situations are explored here in the first situation both the parties have no individual profit target from the business whereas in the second situation there are individual profit target for both the parties the proposed mechanism for division of surplus is studied through a numerical study and the impact of different parameter values on the results are examined

revisiting foundations in lot sizing connections between harris crowther monahan and clark abstract while many review articles exist on deterministic lot sizing models used in the context of price and quantity discounts buyer vendor coordination supply chain management and joint economic lot sizing problems they do not convey the impact of important findings which date back to at least 2002 or in hindsight to 1984 as a result many recent articles still model the financial implications of lot sizing decisions without having the assurance that these models would help the firm s involved in maximising the net present value npv this paper therefore reviews these findings while adding also its own contributions as to convey the general importance to lot sizing theory we show that the underlying principles used in the four key articles that have led to a division in modelling approaches are in fact all in line with npv and argue that therefore there should not be these discrepancies that currently persist in the literature we establish the connections between these four strands of the literature using the solution to a simple variation of harris eoq model deriving thereby results from boyaci and gallego 2002 and beullens and janssens 2011 but showing their general applicability to any type of supply chain structure the breath of implications to deterministic lot sizing theory is illustrated using practical examples we present a stochastic version of the model of crowther 1964 which is arguably the least understood and applied model but on the other hand the most important one in realising how these modelling strands can be unified

effect of partial cross ownership on supply chain performance abstract partial cross ownership pco in a dyad supply chain refers to a situation where each firm holds a portion of its partner s shares we study this topic in push and pull supply chains and prove that neither the supply chain s nor any member s profit changes with the percentage of the leader s shares the follower holds however while the profits of the chain and the leader increase with the percentage of the follower s shares held by the leader the follower s profit does not necessarily increase or decrease as a result both partners can always achieve a win win by setting a proper price for transferring the follower s shares to the leader moreover the equilibrium wholesale price may be greater than the retail price in the push chain but less than the marginal production cost in the pull chain contradicting the usual results found in the literature we also derive a necessary and sufficient condition on the structure of pco allowing a pull chain to perform better than a push one this extends cachon 2004 s result that a pull chain always performs better than a push one without pco finally pco can coordinate a chain if and only if each one holds half of the other s shares

evaluation of capital costs in a multi level inventory system by means of the annuity stream principle abstract in this paper some results obtained from applying the annuity stream principle for evaluating capital tied up in inventory and work in progress and presented this principle departs from the cashflows associated with the production inventory processes considered in contrast to traditional procedures by which the inventory value is determined from physical stock evaluated at costs incurred to date in many situations it appears that the traditional procedure will underestimate the amount of capital tied up in production in this paper the two principles are applied to a multi level inventory system and the capital cost expressions and optimal order quantities are compared

banks responses to deregulation profits technology and efficiency the deregulation of interest rates in the early 1980s raised bank funding costs and lowered profits in response banks raised fees for deposit services reduced branch operating costs and shifted to higher earning assets rates of return did not regain their prederegulation levels until the early 1990s our goal is to decompose the change in bank profits following deregulation into i intemal bank initiated adjustments to the new regulatory structure and ii external contemporaneous changes in banks business environment this decomposition will depend in part on the assumed competitive structure of the banking industry with perfect competition output and input prices are part of the external environment and banks responses are limited to changes in output and input quantities an alternative approach assumes imperfect competition where banks have some control over output prices deposit fees minimum balance requirements and interest rates on certain loans and output quantities and input prices comprise the external environment the altemative model is supported by the data using this model large banks but not smaller banks are found to have relied primarily on changing output prices and input use to mitigate and reverse the negative effects of deregulation on profits the adjustment to deregulation was essentially complete after four years following this additional changes in bank profitability during the late 1980s were primarily due to changes in banks business environment

effects of deregulation on failing thrift institutions the purpose of this paper is to test the hypothesis that much of the decline in the net worth of the failing saving and loan institutions was a result of deregulation variables are developed to represent major actions to deregulate sltime series analysis is developed to estimate the effects of financial deregulation on failing thrifts net worth the data are 1984 89 balance sheet adn income statement data for thrift institutions prior to the enactment of the 1989 legislation to solve the crisis the reuslts of the analysis indicate that deregulation of asset and deposit activities was not the cause of the financial distress of failing us thrift institutions the primary cause appears to be the increase in the federal deposit insurance limit to 100 000 and how attractive this legislative action made brokering deposits that became insured up to 100 000

inventory models with variable lead time and present value the figures for inventory make up a huge proportion of a company s working capital because of this we formulated the optimal replenishment policy considering the time value of money to represent opportunity cost in this article we provide a mixed inventory model in which the distribution of lead time demand is normal to consider the time value first the study tries to find the optimal reorder point and order quantity at all lengths of lead time with components crashed to their minimum duration secondly we develop a method to insure the uniqueness of the reorder point to locate the optimal solution finally some numerical examples are given to illustrate our findings

ordering and inventory policies for step changes in the unit item cost a discounted cash flow approach this paper considers the problem of determining the optimal ordering quantities of a purchased item where there are step changes in price either up or down other costs incurred include ordering costs associated with each replenishment and holding costs related to capital tied up in inventory and physical stock holding the net present value npv principle is applied explicit expressions for the development of the optimal order quantities over time are presented it is shown that three cases may be distinguished i when the price change is very small ii when an essential price increase occurs and iii when there is an essential price decrease although the optimal last order quantity before a price increase is similar in magnitude to what has been presented in other articles applying average cost approaches in certain respects this paper offers novel results contradictory to those suggested by other authors analysis shows that the average cost model solutions are first order approximations in the discount rate numerical evaluations of a range of price increases and times to the price increase suggest that with certain important caveats the average cost formulae are likely to be acceptable for most practical situations for the infinite horizon situation

revealing weak form inefficiency in a market for state contingent claims the importance of market ecology modelling procedures and investment strategies this paper examines the degree to which current prices discount historical prices in a market for state contingent claims conditional logit analysis is employed to predict winning probabilities based on market prices in a betting market these are used together with various wagering strategies to yield substantial abnormal returns consequently in contrast to the existing literature the results suggest that the market is not weak form efficient the disparity with previous efficiency studies highlights the importance of considering market ecology and of adopting an appropriate modelling procedure and investment strategy to fully exploit information contained in market prices

racetrack betting and informed behavior abstract horse racing data permit interesting tests of attitudes toward risk the present paper studies a new sample of racetrack results from atlantic city new jersey the questions examined are 1 are the market odds the best data for predicting the order of finish 2 do horses go off at odds that reflect their true probability of winning 3 is there any evidence that late bettors have better information than early bettors it is found that market odds predict the order of finish well but that favorites are good bets and long shots are poor ones the data suggest that there does exist an informed class of bettors and that bettors are on the whole neither risk neutral nor risk averse

the impact of economic regulation on attempts to curb expense preference behavior a micro data analysis of ceo compensation schemes for electric utilities this study uses a large micro data set to present evidence which suggests that owners of regulated electric utilities have little incentive to structure ceo compensation packages in an effort to curb potential expense preference behavior because such potential behavior occurs or would occur at no cost to the firm or the firm s owners little incentive exists to structure compensation schemes in a way that would curb such behavior e g by compensating them with incentive bonus plans and stock options the results presented here augment those which examine other industries e g banking in an effort to point out the relationships between ownership organization political involvement and expense preference behavior

market efficiency and the favorite longshot bias the baseball betting market this paper examines the efficiency of the legal gambling market for major league baseball weak form tests of market efficiency within and across odds lines are performed surprisingly the consistently observed favorite longshot bias in racetrack betting is shown to exist in reverse for baseball bettors however these and other deviations from efficiency are shown to be insufficient to allow for profitable betting strategies when commissions are considered

exploring decision makers use of price information in a speculative market we explore the extent to which the decisions of participants in a speculative market effectively account for information contained in prices and price movements the horse race betting market is an ideal environment to explore these issues a conditional logit model is constructed to determine winning probabilities based on bookmakers closing prices and the time indexed movement of prices to the market close we incorporate a technique for extracting predictors from price odds curves using orthogonal polynomials the results indicate that closing prices do not fully incorporate market price information particularly information that is less readily discernable by market participants

optimal lot sizing for an unreliable production system based on net present value approach abstract the paper considers the net present value npv approach to determine the economic manufacturing quantities for an unreliable production system over an infinite planning horizon the npv of the expected total cost is obtained under general failure time and general repair time distributions and its asymptotic characteristics are examined by perturbation of the instantaneous discount rate the criteria for the existence and uniqueness of the optimal production time lot size are derived under exponential failure and constant zero repair time the performance of the npv model is compared with the traditional long run average cost model in terms of the npv of the expected total cost based on the optimal decisions of the two models from numerical experiments it is observed that the decision based on the average cost can be 10 worse than the decision based on the npv depending upon the machine failure rate

an inventory model for deteriorating items with stock dependent consumption rate and shortages under inflation and time discounting this paper derives an inventory model for deteriorating items with stock dependent consumption rate and shortages under inflation and time discounting over a finite planning horizon we show that the total cost function is convex with the convexity a simple solution algorithm is presented to determine the optimal order quantity and the optimal interval of the total cost function the results are discussed with a numerical example and particular cases of the model are discussed in brief a sensitivity analysis of the optimal solution with respect to the parameters of the system is carried out

signalling by direct disclosure under asymmetric information abstract in this paper an informational asymmetry exists between investors and the issuer of an initial public offering about the value of the security to avoid market failure a solution is proposed in which the issuer makes a disclosure about firm value that is verified by an investment banker the investment banker enters into a contingent contract with investors which imposes a penalty if the ex post observable cash flow indicates fraudulent disclosure a bivariate signalling model is formulated and solved and testable implications are derived from comparative statics analysis

bettor handicapping and market efficiency in greyhound parimutuel gambling this paper evaluates the speculative efficiency of the parimutuel gambling market for greyhound racing the efficiency tests consider the informational content of bettor handicapping data as well as the forecasts of professional handicappers and the aggregate market previous studies have failed to consider the wide range of performance data that are available for bettor handicapping activities two tests of efficiency are considered the first test evaluates the in sample explanatory power of the handicapper s forecasts and handicapping data relative to the aggregate market s forecasts as indicated by the final odds the second test compares simulated rates of return to hypothetical gambling obtained from ex ante finish forecasts to the efficient rates of return that are dictated by the track s commission significant speculative inefficiencies are revealed the second test suggests the existence of above normal returns to gambling from using conditional forecasts generated from bettor handicapping data

the dominance of inefficiencies over scale and product mix economies in banking abstract this study measures and analyzes inefficiencies for all u s banks in 1984 inefficiencies are measured relative to a thick frontier cost function and are found to dominate measured scale and product mix economies most inefficiencies are operational in nature involving the overuse of physical inputs rather than financial involving overpayment of interest also technical inefficiencies proportionate overuse of all inputs dominate allocative inefficiencies improper mix of inputs these results suggest that competitive pressures in banking from deregulation will be focused primarily on banks that do not control costs rather than on those of a particular size or product mix

expense preference behavior in the savings and loan industry neoclassical microeconomic theory traditionally has assumed that the decision process in the firm is guided by the objective of profit maximization a number of economists have suggested however that managers may pursue goals which maximize personal utility rather than firm profitability 1 10 11 23 24 conditions under which managerial discretion may be substituted for profit maximization include weak competition in the product or service market a high degree of regulation and the separation of ownership and control under these conditions managers have greater opportunity to indulge in discretionary expenditures and the pursuit of managerial emoluments that is managers may seek to achieve a higher level of personal utility via higher salaries additional staff and other perquisites for which they have positive preferences in general this results in an expansion of expenditures beyond the profit maximizing level and a suboptimal x inefficient use of resources within the firm the expense preference theory of the firm recently received considerable support by the work of edwards 3 in which he developed a test to distinguish between expense preference and profit maximizing behavior upon application of this test to the banking industry edwards found that the number of employees and bank expenditures on wages and salaries are higher in noncompetitive banking markets

optimal time varying lot sizing models under inflationary conditions abstract this paper deals with the inventory replenishment problem over a fixed planning horizon for items with linearly time varying demand and under inflationary conditions we develop models and optimal solution procedures with and without shortages we do not put any restriction on the length of the replenishment cycles making the proposed methods the first optimal solution procedure for this problem using four examples we illustrate the proposed solution procedures and study the effect of changing the inflation and discount rates on the optimal replenishment schedules

product bundling and a rule of thumb versus the harville formulae can each way bets with uk bookmakers generate abnormal returns bookmakers practise a type of product bundling to bet a horse for a place a punter has to bet an equal amount for a win the returns to the place component of the bet are determined by a rule of thumb this paper examines whether the product bundling negates a betting strategy that endeavours to exploit any inefficiency in pricing of the place component of each way bets based on the harville formulae in order to implement the harville formulae shin probabilities are employed which correct for the favourite longshot bias in starting price odds as measures of win probabilities the analysis suggests that small positive expected returns to each way bets appear to exist

signaling and the valuation of unseasoned new issues a comment in the march 1982 issue of this journal david downes and robert heinkel 1 present an empirical examination of the role of signaling in the valuation of initial public offerings of common stock for a large sample of unseasoned new issues they examine the leland pyle 2 signaling hypothesis that firm value should be positively related to the fraction of equity retained by the original shareholders downes and heinkel conclude that the data are consistent with the leland pyle signaling hypothesis in this comment i present a more complete test of the leland pyle signaling model i also present two alternative explanations for the positive empirical relation between firm value and insider holdings which i label the agency hypothesis and the wealth effect hypothesis i find that the testable implications of the agency hypothesis are supported while the evidence is ambiguous with respect to the testable implications of the wealth effect and signaling hypotheses

new issues on the u k unlisted securities market the ability of entrepreneurs to signal firm value the present paper investigates whether small firm entrepreneurs are able to signal the value of their firms to potential investors when seeking a listing on the u k unlisted securities market usm the signals considered are the percentage of equity retained by the original entrepreneurs the net proceeds raised by an issue the choice of advising agents to an issue the disclosure of an earnings forecast and the level of underpricing of the new issue in addition the possible interactions between the individual signals are considered and included in the analysis the results of the empirical analysis suggest that firm value is positively and significantly related to the percentage of retained equity and the net proceeds raised thus suggesting therefore that stock markets will invest at higher values ceteris paribus if entrepreneurs indicate confidence in their enterprises via levels of equity retention and the funds they intend to invest in future projects

the demand for casino gaming in this study an econometric model is developed to examine the determinants of the demand for casino gaming specifically the demand for slot machine wagering at riverboats and racinos in addition to examining the effects of traditional demand variables the effect on wagering of variables such as location of a wagering facility and of government restrictions is examined a unique measure of accessibility of market area customers to a facility and to competing facilities was developed the demand for wagering at a facility was found to increase as access by customers in its market area increases and to decrease as access by its customers to competing riverboats racinos or indian casinos increases government restrictions were found to have an adverse effect on wagering at a riverboat on the other hand wagering at a riverboat was found to increase when such restrictions were imposed on competing riverboats the presence of total loss limits and restrictions on boarding times at a riverboat were found

savings and loan ownership structure and expense preference abstract this paper studies the influence of ownership structure on managerial expense preference behavior the hypothesis is that the greater the diffusion of ownership the weaker is the monitoring by owners and the greater is the degree of expense preference behavior whereas expense preference behavior affects inputs particularly on the job consumption of managers well functioning managerial labor markets should resolve the problem by equating the total compensation of managers across firms of different ownership structures a more serious problem however is the potential impact of expense preference behavior on output evidence from the savings and loan industry is adduced indicating that the more diffuse ownership structures associated with mutuality exhibit greater agency costs through the expansion of inputs and outputs beyond profit maximizing levels

misunderstanding of the binomial distribution market inefficiency and learning behavior evidence from an exotic sports betting market abstract this paper uses the setting of a volleyball game and an exotic sports betting on the point difference of volleyball games to test whether people correctly understand the probabilities related to outcomes of a process which follows a binomial distribution we find that people consistently underestimate the probabilities of outcomes that correspond to extreme ends of the distribution this is consistent with the extremeness aversion bias documented in decision making studies whereas previous studies on the extremeness aversion bias find the existence of the bias in a consumer choice setting we document that this bias also exists in an investment setting we find evidence of learning behavior over time however it is not sufficient to eliminate the bias

planning for shortages net present value analysis for a deteriorating item with partial backlogging abstract this paper develops inventory models to help answer strategic questions concerning whether planning for shortages offers financial benefits a production inventory system producing a deteriorating product in batches at a finite production rate with partial backordering is considered customers pay a deposit when placing a backorder backordered items receive a discount on the sales price as lost sales may lead to customers not returning the demand rate may depend on the fraction of lost sales we develop a cash flow based profit maximising net present value npv model without the inventory cost parameters commonly used in this context unit holding cost unit backorder cost unit deterioration cost and unit lost sales cost the model finds the optimal inventory policy just like npv models that discount the traditional parameters but has the advantage of not needing to estimate the value of the traditional parameters it is shown that in models based on discounting the traditional parameters the parameters are not exogenously determinable but are non trivial functions of non financial endogenous system parameters such as the production rate annual demand rate and backorder rate extensive numerical experiments illustrate how cash flow npv models provide insights into the value of planning for shortages and strategic choices about the design of the production inventory system it also provides insight into the classical problem of how to interpret unit backorder cost and unit lost sales cost the study indicates that these insights cannot be reliably obtained from npv models based on discounting unit backorder costs and unit lost sales costs

frontier estimation and firm specific inefficiency measures in the presence of heteroscedasticity the purpose of this article is to illustrate a straightforward and useful method for addressing the problem of heteroscedasticity in the estimation of frontiers a heteroscedastic cost frontier model is developed and estimated using bank cost data similar to that used by ferrier and lovell our results show dramatic changes in the estimated cost frontier and in the inefficiency measures when accounting for heteroscedasticity in the estimation process we find that the rankings of firms by their inefficiency measures is affected markedly by the correction for heteroscedasticity but not by alternative distributional assumptions about the one sided error term

production and inventory model using net present value using the net present value is the standard methodology in theoretical analysis and the most frequently used method for making financial decisions however net present value is rarely used in production and inventory decisions the main reasons appear to be the complexity of the formulae and the robustness of the eoq model we investigate the general multiproduct multistage production and inventory model using the net present value of its total cost as the objective function a power of two heuristic gives us a near optimal solution to this problem if the base period is fixed or varied the solution based on the best power of two heuristic will be within 6 2 or 2 1 of the optimal this result is surprisingly similar to models using the long term average cost the average cost does not reflect the time value of money does this mean that decisions based on average cost are significantly inferior to those based on net present value the answer is quite surprising if we include discounted production cost in the holding cost it turns out that the decision based on average cost is only 9 6 in terms of the net present value of the total cost worse than the decision based on the net present value however the reorder interval based on the average cost could be much longer than that derived using net present value this result shows that average cost is a good approximation to the net present value when the demands are deterministic

effects of discounting and demand rate variability on the eoq the economic order quantity eoq formula is probably the most well known formula in inventory theory it determines the optimal value of the ordering quantity by minimizing the average cost in an ordering cycle it is based on the assumptions that there is a fixed lead time and a constant demand rate these assumptions are usually not fulfilled in practice especially when dealing with slow moving items demand seems to fluctuate furthermore since the time between two successive orderings is often large for slow moving items discounted costs instead of average costs should be minimized in this paper we determine the optimal ordering quantity if demand is modelled by a poisson process and the expected discounted costs are minimized we also analyze the case where demand is uniform and or the average cost criterion is used we give graphical presentations of the optimal ordering quantities besides easily determining the optimal values these allow us to show what the effects of changing the objective function and of changing the demand distribution are we derive a simple discounted cost ordering quantity formula denoted by eoq d for slow moving items we show that for items with a small demand rate and high fixed ordering costs the eoq d is much closer to the optimal discounted cost ordering quantity than the traditional eoq formula c 1998 elsevier science b v all rights reserved

semiparametric distribution free testing of the expectations hypothesis in a parimutuel gambling market the expectations hypothesis maintains that a current forward or futures price should be an unbiased forecast of the expected future price this article tests the expectations hypothesis in the parimutuel gambling market for greyhound racing using parametric and semiparametric estimators parimutuel gambling markets are similar to speculative asset markets in many regards conventional maximum likelihood tests of asset pricing require a priori specification of the statistical distribution governing agents expectations distributional misspecifications may bias conventional tests the semiparametric estimators applied in this article overcome these problems and in addition maintain consistency under heteroscedasticity the results reject the expectations hypothesis

testing for expense preference behavior mutual versus stock savings and loans this article investigates expense preference behavior in the savings and loan industry previous studies used an intercept test and in general concluded that managers of mutual s ls exhibit expense preference behavior i derive the necessary and sufficient conditions on cost functions for the intercept test to be valid these restrictions are rejected for the savings and loan industry stock and mutual s ls have different cost structures and both have non cobb douglas production technologies i derive a new more general test for expense preference behavior that does not require the restrictive assumptions of the intercept test the results of this test do not support earlier conclusions of managerial expense preferences
