is there private information in the fx market the tokyo experiment it is a common view that private information in the foreign exchange market does not exist we provide evidence against this view the evidence comes from the introduction of trading in tokyo over the lunch hour lunch re turn variance doubles with the introduction of trading which cannot be due to public information since the flow of public information did not change with the trading rules having eliminated public information as the cause we exploit the volatility pattern over the whole day to discriminate between the two alternatives private information and pricing errors three key re sults support the predictions of private information models first the vola tility u shape flattens greater revelation over lunch leaves a smaller share for the morning and afternoon second the u shape tilts upward an impli cation of information whose private value is transitory finally the morning exhibits a clear u shape when tokyo closes over lunch and it disappears when trading is introduced

joint pricing and ordering policy for two echelon imperfect production inventory model with two cycles abstract this study deals with an imperfect epq economic production quantity price dependent inventory model over two types of cycles in the first cycle the retailer sells only good product with actual price and in the second he sells the products with a discount price in the production run time the non conforming items are produced at a random rate and they are reworked after the regular production run time and the reworked items are almost perfect as good as original quality items the retailer starts the second cycle when a certain percent of good items are left to him after the completion of regular production the retailer continues simultaneously two cycles up to which both types of the products are available to him now our objective is to find out optimal ordering lot size and optimal price for which the profit of the integrated model is maximum also we check the best strategy of retailer for the time of starting second cycle a numerical example is provided to illustrate the behavior and application of the model

an approach to poverty alleviation for large international development agencies abstract this essay explores the nature of the poverty alleviation problem from the perspective of international development funding agencies these agencies have been poorly structured to promote the interests of the poor agencies such as the world bank and the us agency for international development usaid can achieve better results by creating independent units devoted exclusively to poverty alleviation these units should immerse their staff more completely in local societies with lower pay scales and longer tours of duty a revised form of cost benefit analysis around which these units should orient their work is presented previous analyses of poverty alleviation opportunities and failures have neglected funding agency influences

economic order quantity models for imperfect items with buy and repair options abstract one of the celebrated extensions of the economic order production quantity eoq epq model is one that assumes a received shipment contains a fraction of imperfect non conforming quality items where these items detected by 100 screening are sold as a single batch at a discounted price this paper revisits this model salameh and jaber 2000 int j prod econ 64 1 59 64 and extends it by assuming that a shipment is coming from a distant supplier and therefore it is not feasible to replace the imperfect items with an additional order to the same supplier to address this restriction two models are presented the first assumes that imperfect items are sent to a repair shop who charges a cost plus a markup margin while the second model assumes that imperfect items are replaced by good ones from a local supplier at a higher cost the inventory environment assumed in this paper is relevant in todays globalised supply chains thus practical implications of the problem faced are discussed numerical results are also presented and discussed the results show that there exists a threshold value of the unit purchase cost of an emergency ordered item and a fraction of defectives to which it is decided to either buy or repair

note on economic production quantity model for items with imperfect quality a practical approach abstract in this note we present a simple approach for determining the economic production quantity for an item with imperfect quality we compare the results based on the simple approach with the optimal method for determining the lot size and show that almost optimal results are obtained using the simple approach

why get technical corruption and the politics of public service reform in the indian states the emergence of new information and communication technologies in the 1990s offered governments opportunities to deliver public services more effectively to their citizens yet national and subnational authorities have employed such technologies in highly uneven ways drawing on a new data set of technology policy adoption by indian states the author argues that political calculations drive variation in the timing and scope of technology policies politicians weigh the expected electoral benefits from providing new goods to citizens against the expected electoral costs of reduced access to corrupt funds because of increased transparency the author shows that the level of bureaucratic corruption in a state is the best predictor of both when states implement policies promoting computer enabled services and the number of services made available this finding contrasts with arguments that posit economic or developmental conditions or alternative electoral and institutional characteristics as the major dri

transaction costs order placement strategy and existence of the bid ask spread by considering investor order placement strategy this paper demonstrates that transaction costs cause bid ask spreads to be an equilibrium property of asset markets with transaction costs the probability of a limit order executing does not go to unity as the order is placed infinitesimally close to a counterpart market quote thus with certainty of execution at the counterpart market quote a gravitational pull is generated that keeps counterpart quotes from being placed infinitesimally close to each other an equilibrium spread is defined and its size linked to market thinness implications are noted for the design of a trading system

price formation and liquidity in the u s treasury market the response to public information the arrival of public information in the u s treasury market sets off a two stage adjustment process for prices trading volume and bid ask spreads in a brief first stage the release of a major macroeconomic announcement induces a sharp and nearly instantaneous price change with a reduction in trading volume demonstrating that price reactions to public information do not require trading the spread widens dramatically at announcement evidently driven by inventory control concerns in a prolonged second stage trading volume surges price volatility persists and spreads remain moderately wide as investors trade to reconcile residual differences in their private views how do financial markets form prices and provide liquidity when information arrives efforts to address this issue have led to an extensive microstructure literature on equity markets and to a lesser extent on the foreign exchange fx market relatively little work has focused on the u s treasury market however in spite of its importance in its own right and the advantages it offers as an alternative testing ground for microstructure hypotheses

efficient inventory control for imperfect quality items in this paper we present a general eoq model for items that are subject to inspection for imperfect quality each lot that is delivered to the sorting facility undertakes a 100 per cent screening and the percentage of defective items per lot reduces according to a learning curve the generality of the model is viewed as important both from an academic and practitioner perspective the mathematical formulation considers arbitrary functions of time that allow the decision maker to assess the consequences of a diverse range of strategies by employing a single inventory model a rigorous methodology is utilised to show that the solution is a unique and global optimal and a general step by step solution procedure is presented for continuous intra cycle periodic review applications the value of the temperature history and flow time through the supply chain is also used to determine an efficient policy furthermore coordination mechanisms that may affect the supplier and the retailer are explored to improve inventory control at both echelons the paper provides illustrative examples that demonstrate the application of the theoretical model in different settings and lead to the generation of interesting managerial insights

bad loans to good friends money politics and the developmental state in south korea why has the literature on asian development not addressed the issue of money politics in south korea how can we reconcile the view of an efficient developmental state in south korea before 1997 with reports of massive corruption and inefficiency in that same country in 1998 and 1999 politics is central to the answer in this study i make two arguments first money politics was extensive in south korea both during and after the high growth era second political not economic considerations dominated policymaking this study explains both past and present and compares the patterns of money politics in the early post independence era with those that arose after the democratic transition in 1987 while during the park era a balance of power between businessmen and politicians kept corruption from spinning out of control the transition to democracy altered the basic business state relationship allowing business to exert greater influence over policy decisions the political hypothesis advanced in this study suggests a new direction for our research about the developmental state

eoq models for a coordinated two level international supply chain considering imperfect items and environmental impact abstract for a two level supply chain models are presented to determine the optimal production shipment policy for items with imperfect quality in three different scenarios a both the vendor and the buyer are in the same country b the vendor and the buyer are in different countries where the stochastic behavior of the exchange rate between the two countries is modeled using a mean reverting process and c environmental impact is incorporated in determining the optimal production shipment policy by taking into account the fixed and variable carbon emission costs the objective is to minimize the total expected cost per unit time for each scenario considering equal shipment size the total expected cost per unit time is derived and the solution procedure is proposed numerical examples are presented and the results are discussed

rent seeking and gender in local governance abstract the paper examines the relationship between corruption and gender in the context of local government in india using a logit model recent debates about women s participation in electoral politics suggests that the presence of more women in government will engender public policy and also tends to reduce corruption the evidence we examined indicates that gender is not a significant factor in explaining levels of corruption although nearly 40 per cent of the elective positions in the institutions of local government are occupied by women there is no significant gender difference in attitudes towards rent seeking or in actual levels of corruption between male and female representatives

the interaction between the frequency of market quotations spread and volatility in the foreign exchange market there is an empirical relationship between volatility average spread and number of quotations in the foreign exchange spot market the estimation procedure involves two steps in the first one the optimal functional form between these variables is determined through a maximization procedure of the unrestricted var involving the box cox transformation the second step uses the two stage least squares method to estimate the transformed variables in a simultaneous equation system framework the results indicate that the number of quotations successfully approximates activity in the spot market furthermore the number of quotations and temporal dummies reduce significantly the conditional heteroskedasticity e ect we also discuss information aspects of the model as well as its implications for financial informational theories inter and intra day patterns of the three variables are also revealed

market mediating behavior an economic analysis of the security exchange specialists abstract optimal pricing strategies have been proposed by many authors for security exchange specialists successful application of these algorithms requires specialists to behave as if they knew the equilibrium strategy for a complicated dynamic game real life security exchange specialists actually use relatively simpler price adjustment rules the current paper carries out an economic analysis of one of these rules the analysis suggests that to make a viable market the specialist has to churn the market and to behave optimally he may have to sacrifice his affirmative obligation to maintain a fair and orderly market the analysis also suggests that the direct tick test is not an adequate test of the specialist s affirmative obligation a more comprehensive test should include the test of price adjustment speed

implementing economic policy reforms policies and opportunities for donors abstract african countries trying to cope with crippling economic problems by liberalizing their economies are facing major problems in implementing the reforms international organizations are responding by offering technical assistance typically however the assistance is based on limited and technocratic models that overlook the fact that many of the reforms are unimplementable reforms are complex and uncertain they impose significant political costs their values are generally incompatible with the prevailing political philosophy they involve changing roles they alter power relations within the government and they are identified with outsiders the dominant approaches to implementation privatization training and enhanced control by central ministries underestimate the extent to which the reforms undermine traditional practices the study recommends a fourth approach to address these challenges it relies on designing reforms in collaboration with those who will be in charge of implementing them

the incidence and persistence of corruption in economic development abstract economic development and bureaucratic corruption are determined jointly in a dynamic general equilibrium model of growth bribery and tax evasion corruption arises from the incentives of public and private agents to conspire in the concealment of information from the government these incentives depend on aggregate economic activity which in turn depends on the incidence of corruption the model produces multiple development regimes transition between which may or may not occur in accordance with recent empirical evidence the relationship between corruption and development is predicted to be negative

decentralizing antipoverty program delivery in developing countries we study the effects on accountability in government service delivery of decentralizing administration of an antipoverty program while governments at both central and local levels are vulnerable to antipoor policy biases owing to political capture centralized delivery systems are additionally prone to bureaucratic corruption owing to problems in monitoring bureaucratic performance decentralizing the delivery system promotes cost effectiveness and improves intraregional targeting at low program scales but interregional targeting may deteriorate as central grants to high poverty regions shrink owing to high capture of local governments by local elites in such regions

an eoq model with imperfect quality items inspection errors shortage backordering and sales returns abstract in practice the items received in a lot may contain defective items and the screening process to eliminate the defective items may involve both a type i and a type ii error due to the defective items and the inspection errors shortages may sometimes occur in this paper we develop an economic order quantity model with imperfect quality items inspection errors shortage backordering and sales returns a closed form solution is obtained for the optimal order size the maximum shortage level and the optimal order reorder point if shortages are not allowed we adopt the order overlapping scheme proposed by maddah et al 2010 computers and industrial engineering 58 4 691 695 to develop an eoq model to prevent shortages during the screening process numerical examples show the impacts of the defective probability the inspection errors and the holding and backordering costs on the optimal solution

liquidity costs and stock price response to convertible security calls firms announcements to call in the money convertible securities for redemption essentially force their conversion into common stock and such announcements are generally met with significant reductions in the calling firms equity values an explanation based on liquidity costs is advanced and tested the explanation implies that investors who choose to sell their shares early in the conversion period bear liquidity costs by selling at reduced prices consistent with the explanation the average share price decline is short lived lasting most of the conversion period thus a component of the call announcement effect appears to be due to liquidity costs copyright 1992 by university of chicago press

do special economic zones induce developmental spillovers evidence from india s states abstract do special economic zones induce local development research drawing on the case of china s special economic zones suggests that subnational polities can target the location of export zones in order to catalyze local and regional socioeconomic development since 2006 a number of indian states have pushed forward similar zones in the face of accusations of land grabbing arguing that the zones will be engines for improvement in exports employment and infrastructure i argue that local development spillovers are an important albeit previously understudied dimension by which to evaluate the effects of special economic zones i then present the first systematic analysis of the developmental effects of india s sezs leveraging an original dataset on their locations together with 2001 and 2011 census data containing a host of social and economic developmental variables the findings show these sezs have failed to bring about local socioeconomic development to explain this absence of developmental spillovers i provide a theoretical framework based on the crucial role of political economy incentive structures facing local politicians i outline the mechanism through which indian state politicians use state owned development corporations for rent capture undermining the potential effectiveness of sezs and leading to their developmental failures the combination of available means for extracting rents and the limited political constraints on such rent extraction leads to a lack of developmental spillovers this framework can also help to explain the difference in the effects of sezs in india and in china these findings have theoretical importance for understanding the conditions under which subnational polities can use export zones and other export policies to catalyze development and practical implications for understanding the mixed pattern of sez success across the world

corruption top down or bottom up this article studies the impact of corruption on an economy with a hierarchical government in particular we study whether centralizing corruption within the higher level of government increases or decreases the total amount of corruption we show that when the after tax relative profitability of the formal sector as compared to that of the informal sector is high enough adding a layer of government increases the total amount of corruption by contrast for high enough public wages and or an efficient monitoring technology of the bureaucratic system centralization of corruption at the top of the government hierarchy redistributes bribe income from the lower level to the upper level in the process total corruption is reduced and the formal sector of the economy expands

bureaucratic delays and bribe taking abstract bureaucrats in ldcs are known to often elicit bribes by delaying the processing of documents applications submitted by private agents this paper models this practice and discusses two procedures to control the consequent social welfare loss we show that compared to the situation with no sanctions on bribe taking imperfect vigilance coupled with penalties for bribe taking leads to more frequent delays and a pareto inferior solution a superior governance mechanism involves a reward penalty scheme based upon the average time taken to clear applications an efficiency wage may have to be paid to implement this solution

eoq with a correlated binomial supply abstract this paper considers a variant of the economic order quantity eoq model under random supply a binomial supply model is adopted where every item received is of imperfect quality with the same probability we study the realistic case where the qualities of items in an order are correlated and draw useful insights the most interesting of which is that correlation decreases the order size several practical correlation patterns are investigated and discussed we also show that several commonly used models in the literature can be represented by an equivalent correlated binomial supply model

disaggregation and consolidation of imperfect quality shipments in an extended epq model abstract we consider a standard economic production quantity epq model due to manufacturing variability a fraction p of the produced inventory will have imperfect quality where p is a random variable with a known distribution we consider a 100 inspection policy and further assume that the inspection rate is larger than that of production thus all imperfect quality items will be detected by the end of the production cycle for such an augmented epq model we first derive the new optimal production quantity assuming that the imperfect quality items are salvaged once at the end of every production cycle then we extend this base model to allow for disaggregating the shipments of imperfect quality items during a single production run finally we consider aggregating or consolidating the shipments of imperfect items over multiple production runs under both scenarios we derive closed form expressions for both the economic production quantity and the batching policy and show that our desegregation consolidation schemes can lead to significant cost savings over the base model

black markets and optimal evadable taxation in a simple model of evadable indirect taxation some surprises emerge because of a market thinning effect of high prices high taxes induce multiple equilibria low price black markets and high price legal markets further evadability introduces a bifurcation to optimal taxation for less effective tax administrations the optimal tax system follows a cash cow pattern with one sector bearing all of the tax but for relatively effective administrations the optimum follows a slightly modified ramsey rule this discontinuity results from the mathematics of evasion incentives and may help explain tax reforms commonly seen over the course of economic development

making markets for structured mortgage derivatives abstract this paper distinguishes between securitization in which simple pass through instruments are created and structuring in which mortgages derivative claims are created the point is to explain how structuring a transaction brings value to a deal s underwriter briefly an underwriter must defeat arbitrage between pass throughs and derivatives the potential for market segmentation and price discrimination by the underwriter is used to analyze the structuring process in the course of the analysis the legal rules for trusts the algebraic rules for structuring and the limits on permissible price discrimination are discussed results for an actual transaction illustrate the important features of the analysis

wealth culture and corruption this paper examines the impact of national wealth income distribution government size and four cultural variables on the perceived level of corruption in a country the study finds that corruption is significantly correlated to gnp per capita power distance masculinity and uncertainty avoidance significant interaction effects occur in collectivistic and high power distance countries suggestions for future research are developed

is there an alternative for irrigation reform summary poor performance of government managed irrigation systems persists in developing countries despite numerous policy interventions over the last four decades we argue that many of these interventions have failed because they did not recognize irrigation bureaucracies as prime actors in policy change this paper examines the varied actors and agendas within irrigation bureaucracies highlighting the dichotomy between hydraulic missions on the one hand and direct service provision to farmers on the other to increase the significance of future reform bureaucracies must be considered as explicit actors and reform efforts should derive from better understanding of the farmer agency interface

covered interest arbitrage profits the role of liquidity and credit risk we study the profitability of covered interest parity cip arbitrage violations and their relationship with market liquidity and credit risk using a novel and unique dataset of tick by tick firm quotes for all financial instruments involved in the arbitrage strategy the empirical analysis shows that positive cip arbitrage deviations include a compensation for liquidity and credit risk once these risk premia are taken into account small arbitrage profits only accrue to traders who are able to negotiate low trading costs the results are robust to stale pricing and the nonsynchronous trading occurring in the markets involved in the arbitrage strategy

corruption and development a review of issues in this paper we start with a discussion of some of the different denotations of the problem of corruption we then consider the ways in which the damaging consequences of corruption operate in a developing economy while not ignoring its possible redeeming features in some cases we pursue the question of why corruption is perceptibly so different in different societies and also persistent finally we examine the feasible policy issues that arise in this context

the microeconomics of market making this paper examines the influence of risk aversion on the pricing policies of a market maker for securities it is shown that a market maker s bid ask spread can be decomposed into a portion for the known limit orders a risk neutral adjustment for expected market orders and a risk adjustment for market order and inventory value uncertainty it is dem onstrated that a risk averse market maker may set a smaller spread than a risk neutral specialist finally this paper demonstrates the pervasive role of inventory in affecting both the placement and size ofthe spread

on intraday risk premia this article presents a framework for analyzing the dynamic effects of anticipated large demand pressures on asset risk premia we show that large institutions who can time their entry into the market will trade either at the open or during periods of unusual demand pressures we show that if these institutions do enter later in the day they trade in the same direction as institutions which provide liquidity continuously institutions therefore appear to exhibit herding behavior we also explore how changing the uncertainty of demand pressures late in the day affects trading costs throughout the day most financial market investors do not continuously monitor intraday fluctuations in stock prices other activities e g outside employment often take precedence over following the stock market and there are limitations to processing information for example a reader of this page is likely to be unaware of current financial market prices in fact for many investors entry into financial markets occurs once a day or even less frequently given these institutional realities it is of interest to explore how asset markets react when it is known that a set of very large predictable demands will arrive during the afternoon does their arrival affect prices only when they arrive or throughout the day if the price impact is spread out then how do trading costs behave during the day if some traders have the flexibility to time their entry into the market when will they arrive during the day and how will their entry decisions affect asset risk premia if market participants anticipate that demands in the afternoon will be unusually volatile how does this affect the intertemporal behavior of prices and expected returns earlier in the day the primary focus of this article is the development of tractable methodologies that can address these issues

an optimal policy for a single vendor single buyer integrated production inventory problem with process unreliability consideration abstract this article develops a model to determine an optimal integrated vendor buyer inventory policy for flawed items in a just in time manufacturing environment the objective is to minimize the total joint annual costs incurred by the vendor and the buyer the production process is assumed to deteriorate during processing and produces a certain number of defective items for practical purpose the article is concerned with the policy in which the delivery quantity to the buyer is identical at each replenishment the expected annual integrated total cost function is derived and a solution procedure is established to find out the optimal solution finally the solution technique is illustrated with a numerical example available in the literature

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

the system of administrative and political corruption canal irrigation in south india the paper describes how some irrigation engineers raise vast amounts of illicit revenue from the distribution of water and contracts and redistribute part to superior officers and politicians it argues that the corruption system which is centred on control of personnel transfers is an important supply side reason for poor performance of canal irrigated agriculture insofar as the same system operates in other government departments it may be more important for understanding indian politics and the political influences on economic development than has previously been realised

lot sizing with a markov production process and imperfect items scrapped abstract this paper considers an inventory system within the economic order quantity eoq model framework under random supply the production process can go out of control with a constant probability and start producing imperfect quality items such a system has been studied in the literature under the assumption that defective items are reworked instantaneously and returned to inventory in some situations imperfect quality items are not necessarily defective and are removed from the inventory to be used elsewhere this paper develops two models where imperfect items are removed from inventory the first model finds the expected cost and optimal lot size assuming that imperfect quality items are removed from inventory at no cost the second model assumes that batches of imperfect quality are consolidated and shipped together due to economies of scale in shipping analytical and numerical results are developed for both models revealing several managerial insights

the market for public office why the indian state is not better at development abstract how and why officials are transferred from one post to another can in india does have far reaching consequences for the effectiveness of public service organizations such as irrigation agriculture forestry and soil conservation departments the transfer mechanism used in many departments of indian states involves a kind of internal labor market a truer market than in the way that term is often used by labor market economists it allows pressures for corrupt behavior to bear down on the incumbents of certain posts and itself amplifies those pressures frequently the pressures on officials to be corrupt cause them to behave in ways contrary to the ostensible objectives of their departments why is the indian state not better at promoting development to an important degree because of the corruption transfer mechanism and its effects on bureaucratic initiatives

econometric models of limit order executions we develop and estimate an econometric model of limit order execution times using survival analysis and actual limit order data we estimate versions for time to first fill and time to completion for both buy and sell limit orders and incorporate the effects of explanatory variables such as the limit price limit size bid offer spread and market volatility execution times are very sensitive to the limit price but are not sensitive to limit size hypothetical limit order executions constructed either theoretically from first passage times or empirically from transactions data are very poor proxies for actual limit order executions r 2002 elsevier science b v all rights reserved jel classification g23

foreign aid and conditions precedent political and bureaucratic dimensions abstract international donor agencies increasingly use their influence to press for major reforms in development policies and administrative practices in third world countries reform recommendations are often conceptualized with little regard for the political and bureaucratic contexts in which they are to be adopted and pursued without greater concern for issues of political and bureaucratic feasibility however reform recommendations are likely to have only minimal impact policy space research and administrative systems research are promising approaches for acquiring and analyzing information about the political and bureaucratic aspects of government decision making such analyses can improve the potential for reform recommendations to be adopted and pursued

irrigation reform in conditions of populist anarchy an indian case abstract it is true that the performance of india s canal irrigated agriculture could be substantially and cheaply improved by change in canal operating and maintenance procedures but current procedures allow some farmers and state officials to capture disproportionate benefits for themselves through a well institutionalised system of corruption these beneficiaries of the status quo make up powerful interes groups against reform the paper illustrates just how intensely political irrigation reform can be by tracing what happened when an attempt was made to carry out an apparently simple improvement in water allocation rules under a south indian canal the events suggest a wider process of cumulative causation making for low rates of growth of food production and weaker political authority the process is not inevitable however and the paper ends with some suggestions about how in the irrigation context public policy might help to offset the decline

volatility increases subsequent to nyse and amex stock splits the post split increase in daily returns volatility is less for amex stocks than for nyse stocks the exchange trading location is a significant factor in explaining the volatility shift even after stock price and firm size are considered furthermore when measured on a weekly basis there is no increase in amex stocks returns volatility these results suggest that measurement errors created by bid ask spreads and the 1 8 effect and also one or more of the elements that make the nyse different from the amex explain why the estimated volatility of daily stock returns increases after the ex split date ohlson and penman 1985 provide evidence that nyse stock returns variances increase subsequent to ex stock distribution days for splits of 100 or greater the increase in volatility is independent of the size of the split alnd the post split price seven potential problems that might affect their results are analyzed and rejected 1 ohlson and penman 1985 suggest that the greater post split volatility may be due to the activity of relatively ignorant noisy traders who prefer trading low priced stocks this clientele factor is attributed to black 1986 pg 534 and institutional factors a rather broad category that incorporates measurement problems created by the 1 8 effect and bid ask spreads as possible hypotheses for the post split volatility increase this paper extends ohlson and penman s 1985 analysis to amex stocks exchange listing can serve as a proxy for several real factors that may cause the increase in post split variance many of which are related to the clientele factor and institutional factors cited above if the increase in volatility differs between nyse and amex stocks it will suggest that one or more of the following contributes to the phenomenon

public policy reform and informal institutions the political articulation of the demand for work in rural india summary the emphasis on rights that individual citizens can claim from the state represents a significant institutional development for poverty alleviation policies in india important legislation was passed in 2005 to guarantee rural households 100 days of work paid at a statutory wage rate this right to work legislation has enabled the implementation of the world s largest public works program the mahatma gandhi national rural employment guarantee scheme or nregs this study explores variation in policy outcomes under nregs within a rural district of north india uttar pradesh it finds that this variation is the product of the interaction between formal and informal institutions as such the demand for work benefits does not emerge spontaneously from self selecting rural citizens but is articulated by local elected officials who are pressurised to accommodate demands for rents from the bureaucracy specifically local elected officials are compelled to proceed to a selective activation of the demand for benefits to ensure the generation of a surplus which will form the basis of bureaucratic rent payments the study relies on qualitative data specifically interviews with past beneficiaries of the scheme bureaucrats tasked with policy implementation and elected village leaders the gram pradhans in the indian state of uttar pradesh to document the conditions under which a surplus is extracted and rent payments made the study shows that caste and political leadership structures at the local level affect the generation of surpluses and the payment of rents by gram pradhans to the bureaucracy while the right to work legislation represents progress for poverty alleviation policies such as nregs that emphasize rights and the expression of a demand for benefits need to consider more carefully the conditions under which this demand emerges as well as the ways in which discretionary authority can thwart the goals of public policy

an eoq model with backorders and rejection of defective supply batches abstract we consider a single echelon inventory installation under the classical eoq with backorders paradigm to study the effects of supply quality on cost performance previous research on imperfect supply quality has focused on variants of the proportional deterministic or random yield problem where supply batches are all accepted and then used after screening any defects in this paper we study an alternative setting where entire supply batches may be defective below quality standards and therefore rejected on arrival note that such supply flow disruptions are analogous to those considered within the economic order quantity with disruptions eoqd area of research we first present an exact model for the system expected cost and show its convexity optimal cost and respective values of the decision variables i e planned order quantity and backorders are then obtained in a closed form interestingly under perfect supply quality all expressions reduce to those of classical eoq analytical and computational results reveal the serious impact of inferior supply quality on system cost as well as the sensitivity of the system parameters

are they efficient in the middle using propensity score estimation for modeling middlemen in indian corporate corruption corrupt regulatory environment encourages firms to deploy middlemen for speedy and assured acquisition of different services from regulatory agencies using a world bank dataset of 2210 indian manufacturing firms this article examines how firms with middlemen deal with corrupt governmental agencies for its operational efficiency our results demonstrate that deployment of middlemen by the firms is often accompanied by a substantial increase in operational delay relatively trigger more consumption of senior management s time on regulatory disentanglement enhance the likelihood tendency to pay bribe and likely to face more court cases as a means of restitution of legal rights as firm specific attributes may contaminate our preliminary results we utilized the propensity score framework to examine relationships among variables of interests our study contributes to the inconspicuous part of the corruption literature by attempting to present a comprehensive but indirect assessment of the functions of middlemen that predominantly remained unattended except some scattered descriptive case based anecdotal presentations

economic order quantity for items with imperfect quality revisited abstract we rectify a flaw in an economic order quantity eoq model with unreliable supply characterized by a random fraction of imperfect quality items and a screening process developed by salameh and jaber 2000 economic production quantity model for items with imperfect quality international journal of production economics 64 1 3 59 64 this leads to simple expressions of the optimal order quantity and expected profit per unit time we then analyze the effect of screening speed and variability of the supply process on the order quantity and show that the order quantity in our model is larger than that of the classical eoq model when the variability of the yield rate is reasonably low in addition we extend the model by allowing for several batches of imperfect quality items to be consolidated and shipped in one lot this is likely to be useful when there are economies of scale in shipping of imperfect quality items finally we present numerical results to illustrate the application of the model and draw insights

economic production quantity model for items with imperfect quality abstract the assumptions necessary to justify the use of economic production quantity epq eoq models are rarely met to provide mathematical models that more closely conform to actual inventories and respond to the factors that contribute to inventory costs the models must be extended or altered this paper hypothesizes a production inventory situation where items received or produced are not of perfect quality items of imperfect quality not necessarily defective could be used in another production inventory situation that is less restrictive process and acceptance control the electronics industry gives good examples of such situations this paper extends the traditional epq eoq model by accounting for imperfect quality items when using the epq eoq formulae this paper also considers the issue that poor quality items are sold as a single batch by the end of the 100 screening process a mathematical model is developed and numerical examples are provided to illustrate the solution procedure

an empirical analysis of stock and bond market liquidity this article explores cross market liquidity dynamics by estimating a vector autoregressive model for liquidity bid ask spread and depth returns volatility and order flow in the stock and treasury bond markets innovations to stock and bond market liquidity and volatility are significantly correlated implying that common factors drive liquidity and volatility in these markets volatility shocks are informative in predicting shifts in liquidity during crisis periods monetary expansions are associated with increased liquidity moreover money flows to government bond funds forecast bond market liquidity the results establish a link between macro liquidity or money flows and micro or transactions liquidity a number of important theorems in finance rely on the ability of investors to trade any amount of a security without affecting the price however there exist several frictions 1 such as trading costs short sale restrictions and circuit breakers that impact price formation the influence of market imperfections on security pricing has long been recognized liquidity in particular has attracted a lot of attention from traders regulators

government action social capital and development reviewing the evidence on synergy abstract instead of assuming a zero sum relationship between government involvement and private cooperative efforts the five preceding articles argue for the possibility of state society synergy that active government and mobilized communities can enhance each others developmental efforts this article draws on these articles to explore the forms and sources of state society synergy i argue that synergy usually combines complementarity with embeddedness and is most easily fostered in societies characterized by egalitarian social structures ard robust coherent state bureaucracies i also argue however that synergy is constructable even in the more adverse circumstances typical of third world countries

dealing with dealers sovereign cds comovements abstract we show that sovereign cds that have common dealers tend to be more correlated especially when the dealers display similar quoting activity in those contracts over time this commonality in dealers activity is a powerful driver of cds return comovements over and above fundamental similarities between countries including default liquidity and macro factors we posit that the mechanism causing the excess correlation is the buying pressure faced by cds dealers for credit enhancements and regulatory capital reliefs an instrumental variable analysis helps alleviate the endogeneity concerns in our analysis

leaning against the wind during financial disruptions market makers provide liquidity by absorbing external selling pressure they buy when the pressure is large accumulate inventories and sell when the pressure alleviates this paper studies optimal dynamic liquidity provision in a theoretical market setting with large and temporary selling pressure and order execution delays i show that competitive market makers offer the socially optimal amount of liquidity provided they have access to sufficient capital if raising capital is costly this suggests a policy role for lenient central bank lending during financial disruptions

liquidity and the law of one price the case of the futures cash basis deviations from no arbitrage relations should be related to market liquidity because liquidity facilitates arbitrage at the same time a wide futures cash basis may trigger arbitrage trades and in turn affect liquidity we test these ideas by studying the dynamic relation between stock market liquidity and the index futures basis there is evidence of two way granger causality between the short term absolute basis and liquidity and liquidity granger causes longer term absolute bases shocks to the absolute basis predict future stock market liquidity the evidence suggests that liquidity enhances the efficiency of the futures cash pricing system copyright 2007 by the american finance association

after the decision implementing policy reforms in developing countries abstract implicit in many reform proposals is a model of the policy process that is roughly linear a proposed reform gets on the agenda for government action a decision is made on the proposal and the new policy or institutional arangement is implemented either successfully or unsuccessfully this article presents an alternative interactive model of implementation that focuses on the conflict and reactions that are evoked by efforts to bring about changed policy or institutional contexts for development and the resources that policy makers and managers are likely to require to sustain a reform in the face of such reactions central to the analysis is the assertion that characteristics of the reform being implemented will largely determine the kind of conflict it engenders where such reaction is likely to become manifest and what resources are needed for sustainability the analysis suggests a framework for the strategic management of reform initiatives

a proposal for using incentive precommitments in public enterprise funding abstract among the central problems of less developed countries ldcs is the poor performance of their public enterprises pes and the seemingly limited ability of governments and other agencies to improve this performance this paper proposes that project agencies be induced as a part of the initial financing of pes to undertake specific types of precommitments a precommitment to liquidate the project if its ex post performance falls below some threshold level and a precommitment to link a non negligible part of employee compensation to actual performance our proposal is not guaranteed to improve pe performance because there are no perfect solutions to what is inherently a politically difficult problem nevertheless we argue that as long as public enterprises exist independent of whether this is a good idea or not a precommitment to use performance based incentives is likely to improve their performance we discuss the primary sources of pe losses compare their probable magnitudes and explain how various precommitments are likely to ameliorate such losses our proposal is aimed at stimulating more thought on this subject and is addressed to a broad audience

the personal vote and the efficacy of education spending in this article we explore the ways in which incentives to cultivate a personal vote affect the efficiency of education spending in developing democracies we argue that where the electoral system provides incentives for political particularism resources are allocated less efficiently and the effect of increased spending on literacy is diminished we test our hypotheses using data on education spending and performance in over 40 developing democracies since 1980 we find that though personal vote systems spend just as much on education as party vote systems particularism in personal vote systems dampens the marginal effect of increased education spending on illiteracy and at its highest levels incentives to cultivate a personal vote completely undermine the positive effects of increased education spending on literacy

institution building multilateral development banks and state owned enterprises abstract despite the increasing popularity of privatization in latin america many large and important firms will remain in the public sector and for those firms improved economic performance is essential if a constant drain on developing country treasuries is to be avoided this paper analyzes the improvements in enterprise performance that may occur as a result of cooperation between state owned enterprise soes and multilateral development banks and argues that the combination of softer terms and harder conditions may help soe management increase the operational efficiency of their firms the experience of the paraguayan state firm ande and the inter american development bank is examined and found to provide evidence in support of this hypothesis

stock and bond market liquidity a long run empirical analysis this paper establishes liquidity linkage between stock and treasury bond markets there is a lead lag relationship between illiquidity of the two markets and bidirectional granger causality the effect of stock illiquidity on bond illiquidity is consistent with flight toquality or flight to liquidity episodes monetary policy impacts illiquidity the evidence indicates that bond illiquidity acts as a channel through which monetary policy shocks are transferred into the stock market these effects are observed across illiquidity of bonds of different maturities and are especially pronounced for illiquidity of short term maturities the paper provides evidence of illiquidity integration between stock and bond markets

economic ordering quantity models for items with imperfect quality abstract in this paper we first look at the issue of non shortages in models with proportional imperfect quality when the proportion of the imperfects is a random variable more specifically we revisit the papers of salameh and jaber int j prod econom 64 2000 59 and chan et al prod plann control 14 2003 588 and we point out that the sufficient conditions given in these papers to ensure that shortages will not occur may not really prevent their occurrence next considering the timing of withdrawing the imperfect quality items from stock we clarify a point not clearly stated in salameh and jaber int j prod econom 64 2000 59 and we extented this model to the case in which withdrawing takes place at the end of the planning horizon finally we establish that the objective of maximizing the mean average profit which was set in salameh and jaber int j prod econom 64 2000 59 is superfluous and the results given there can be obtained by ignoring the revenue issues assumed in the model and minimizing directly the mean average cost

stopped in the name of the law administrative burden and its implications for cash transfer program effectiveness summary cash transfer programs have achieved wide ranging success in reducing poverty yet there is little empirical research on how program rules and administrative capacity might limit program effectiveness we examine administrative burden and quantify its implications for grant access and impacts in the south african child support grant csg program as the age of eligibility and application requirements changed over time we find that approximately 60 of the sampled children experienced an interruption or disconnection in cash transfer receipt and that both timing and dosage loss are associated with adolescent engagement in risky behaviors and for females lower educational attainment

the genesis and spread of economic corruption a microtheoretic interpretation abstract this paper argues that the ability to engage in corruption arises from the possession of quasi monopoly power or authority by one of the parties to corruption this authority is passed on routinely through delegation of functions in state and publicly owned enterprises or acquired by explicit or implicit contract with another party or by solemn promise to act in good faith corruption tends to spread by enlisting the support of more individuals within and across activities this support is needed to overcome risks to solve problems of indivisibility and to reap benefits of network externalities

bureaucrats in business chinese style the lessons of market reform and state entrepreneurialism in the people s republic of china in the 1990s parts of the state bureaucracy in china have been setting up new profit seeking risk taking businesses some of these businesses are entrepreneurial rather than rent seeking and are an unplanned and unanticipated development in china s market oriented economic reforms what are the lessons of this phenomenon for the developing world state entrepreneurialism may create problems such as reduced government control over departmental finance loss of state assets and uneven provision of services it is nevertheless an innovative solution to the politically difficult problem of bureaucratic restructuring and confounds the development orthodoxy fostered by neoliberalism that states will resist market reform it also demonstrates that to understand fully the politics of market reform we must research the activities of subcentral state bureaucrats as well as central leaders and policymakers

earnings announcements and attention constraints the role of market design abstract we identify a new channel market makers attention constraints through which earnings announcements for one stock affect the liquidity of other stocks when some stocks handled by a designated market maker have earnings announcements liquidity is lower for non announcement stocks handled by the same market maker with the largest effects coming from earnings surprises and stocks with high earnings response coefficients half of the liquidity decline reflects attention constraints binding on the individual market maker and the other half is explained by the market maker s inventory we further find that a market design change that increases automation alleviates the liquidity effect of attention constraints despite an increase in the number of stocks allocated to each market maker

economic order quantity model for items with imperfect quality with learning in inspection abstract the economic order quantity eoq model is the simplest and earliest inventory model in the literature its simple mathematics is attributed to its assumptions which are rarely met salameh and jaber 2000 economic production quantity model for items with imperfect quality int j prod econ 64 59 64 addressed one of these assumptions that items received or produced are not of perfect quality this paper extends salameh and jaber s work for the case where there is learning in inspection the model is realistic in that it considers situations of lost sales and backorders mathematical models are developed with numerical examples provided and results discussed for the cases of i partial transfer of learning ii total transfer of learning and iii no transfer of learning
