price formation in electricity forward markets and the relevance of systematic forecast errors since the liberalisation of the european electricity sector forward and futures contracts have gained significant interest of market participants due to risk management reasons for pricing of these contracts an important fact concerns the non storability of electricity in this case according to economic theory forward prices are related to the expected spot prices which are built on fundamental market expectations in the following article the crucial impact parameters of forward electricity prices and the relationship between forward and future spot prices will be assessed by an empirical analysis of electricity prices at the european energy exchange and the nord pool power exchange in fact price formation in the considered markets is influenced by historic spot market prices yielding a biased forecasting power of long term contracts although market and risk assessment measures of market participants and supply and demand shocks can partly explain the futures spot bias inefficiencies in the analysed forward markets cannot be ruled out

privatisation around the world evidence from panel data this paper presents new evidence about privatisation processes and their determinants from a panel of 34 countries over the 1977 99 period the empirical analysis shows that privatisation takes place typically in wealthy and democratic countries endowed with deep and liquid stock markets and is affected by the governing political majority and public sector budget constraints but the extent of privatisation in terms of revenues and stakes sold appears more limited in civil law countries where shareholders are poorly protected banks powerful and capital markets less developed

why are developing countries privatization this article tests alternative hypotheses about why developing countries are pursuing privatization a policy that gained considerable popularity in the 1980s univariate and multivariate analysis indicate that privatization was more likely to be pursued by countries with high budget deficits high foreign debt and high dependence on international agencies like the world bank and the imf in regions such as latin america and asia the trend was also more likely in countries a that seemed to have overused state enterprises in the past and b those in which the private sector had grown faster than average and was thus more ready to assume tasks once assigned to state enterprises in africa however the policy may have been imposed by external agencies on countries that were not necessarily ripe for privatization for multinational firms the international opportunities created by privatization are likely to be greater in the 1990s than in the 1980s

privatization and globalization an empirical analysis abstract this paper examines the link between globalization measured by foreign direct investment fdi and foreign portfolio investment fpi and privatization of state owned enterprises in a multi country sample that focuses on developing countries we hypothesize that privatization has an effect on fdi fpi as the process of fostering private sector participation is often accompanied by liberalization reforms and by allocations of substantial shares of newly privatized firms to foreign investors similarly we expect fdi fpi to foster privatization efforts as new capital inflows technology and managerial skills that accompany fdi fpi make the environment more prone to competition providing governments with incentives to privatize inefficient firms that need to be turned around this relation is assessed in two ways first in a dynamic panel using a generalized method of moments approach and second through panel causality tests we find a bi directional positive relation between privatization proceeds and globalization particularly in the case of fdi

an experimental test of combinatorial information markets while a simple information market lets one trade on the probability of each value of a single variable a full combinatorial information market lets one trade on any combination of values of a set of variables including any conditional or joint probability in laboratory experiments we compare the accuracy of simple markets two kinds of combinatorial markets a call market and a market maker isolated individuals who report to a scoring rule and two ways to combine those individual reports into a group prediction we consider two environments with asymmetric information on sparsely correlated binary variables one with three subjects and three variables and the other with six subjects and eight variables thus 256 states

the overnight risk premium in electricity forward contracts abstract we analyze the risk premium on electricity forward contracts traded for the nordic and german austrian electricity markets we argue that finding risk premiums by analyzing overnight returns is more relevant than the frequently used ex post approach the derivatives in these markets can be characterized as trading products and hedging products each contract shows a clear increase in trading volume and liquidity when approaching maturity we link this to a testable hypothesis where financial traders are compensated for holding price risk and where the sign and magnitude of the risk premium changes depending on the hedging pattern of producers and retailers incorporating this in regressions we find that there are higher risk premiums in the period before the forwards become front products compared to the risk premiums in the front period quarterly and monthly contracts show the most significant results

pricing forward contracts in power markets by the certainty equivalence principle explaining the sign of the market risk premium in this paper we provide a framework that explains how the market risk premium defined as the difference between forward prices and spot forecasts depends on the risk preferences of market players and the interaction between buyers and sellers in commodities markets this premium is an important indicator of the behavior of buyers and sellers and their views on the market spanning between short term and long term horizons we show that under certain assumptions it is possible to derive explicit solutions that link levels of risk aversion and market power with market prices of risk and the market risk premium we apply our model to the german electricity market and show that the market risk premium exhibits a term structure which can be explained by the combination of two factors firstly the levels of risk aversion of buyers and sellers and secondly how the market power of producers relative to that of buyers affects forward prices with different delivery periods

human capital and fdi inflows to developing countries new empirical evidence abstract despite the dramatic increase in total foreign direct investment fdi flows to developing countries in the last few years the bulk of the inflows has been directed to only a limited number of countries it has been argued that developing countries might enhance their attractiveness as locations for fdi by pursuing policies that raise the level of local skills and build up human resource capabilities nevertheless the empirical evidence in the literature in support of this recommendation for a large sample of developing countries is scant this paper evaluates this argument in the light of the evolution in the structural characteristics of fdi and empirically tests the hypothesis that the level of human capital in host countries may affect the geographical distribution of fdi the empirical findings are a human capital is a statistically significant determinant of fdi inflows b human capital is one of the most important determinants and c its importance has become increasingly greater through time

carbon pricing and electricity markets the case of the australian clean energy bill abstract we examine the impact of the clean energy bill on the price behavior of electricity futures contracts in the australian national electricity market first we compute ex ante forward risk premiums in the pre tax period until june 2012 then derive market implied expectations about additional costs of the carbon pricing mechanism cpm on generators as well as pass through rates during the carbon tax july 2012 june 2014 and post tax after july 2014 periods our results suggest that the observed carbon premiums became increasingly higher once the carbon tax had been proposed and subsequently legislated in 2011 during periods where market participants could be relatively certain that the tax would be effective we find expected carbon pass through rates between 67 and 150 which seem to be inversely related to emission intensities in the regional markets our results are also a clear indication of strong policy uncertainty with regards to the cpm and suggest that in the future a stable and long term policy framework would be required for a carbon pricing mechanism to have its full effect

introduction to the special issue on behavioral economics and finance we are thrilled to introduce the special issue of management science titled behavioral economics and finance the theories underlying finance and economics have long relied on behavioral assumptions after all risk aversion is merely an observed behavior of individual behavior but it is now well accepted to assume that agents are risk averse surely other common and very human behaviors affect markets and management our goal with this special issue was to provide an outlet for research on these issues we believe that this special issue accomplishes that goal and makes for engaging reading the response to the special issue exceeded our expectation we received 292 submissions we are proud to say we were able to handle this workload with the same high quality review process and turnaround goals maintained by the editorial board at management science more than 90 of papers were reviewed within 90 days we could not have accomplished this goal without the support of many individuals kathleen luckey the tireless and remarkable managing editor of management science provided us with phenomenal support we are truly grateful for her willingness to go the extra mile in handling the large number of papers that we received around the submission deadline the special issue was the brainchild of gerard cachon the editor in chief of management science we are grateful for his visionary leadership of the journal and his willingness to devote scarce journal space and resources to this important topic finally we are indebted to the remarkable group of associate editors who gave of their time and expertise they were critical in ensuring high quality and prompt feedback to those who submitted papers we are amazed at the time and talent that many willingly and ably provide to the research enterprise in the end you have before you 29 papers that are separated into two issues the second issue will publish in february 2012 we have roughly split the papers into a behavioral economics issue and a behavioral finance issue though there is clearly much overlap between the two the papers include experimental theoretical and empirical papers with a common theme they all address questions that are answered with a deeper understanding of human behavior the papers deal with a wide range of behavioral factors that influence outcomes including cultural values social norms social networks attention familiarity and ambiguity aversion to name but a few taken together the papers reveal the promise that behavioral economics and finance hold and provide a strong signal of management science s commitment to the field in closing we thank all of the authors who submitted to the special issue the strong response to our call made the issue a success to those authors whose work appears in the issue thank you for all of your hard work in navigating the review process while being responsive to the deadlines of the special issue

affecting policy by manipulating prediction markets experimental evidence abstract documented results indicate prediction markets effectively aggregate information and form accurate predictions this has led to a proliferation of markets predicting everything from the results of elections to a company s sales to movie box office receipts recent research suggests prediction markets are robust to manipulation attacks and resulting market outcomes improve forecast accuracy however we present evidence from the lab indicating that single minded well funded manipulators can in fact destroy a prediction market s ability to aggregate informative prices and mislead those who are making forecasts based upon market predictions however we find that manipulators primarily influence market trades meaning outstanding bids and asks remain informative

do prediction markets aid defenders in a weak link contest abstract laboratory experiments have demonstrated that prediction market prices weakly aggregate the disparate information of the traders about states moves of nature however in many practical applications one is attempting to predict the move of a strategic rival this is particularly important in aggressor defender contests this paper reports an experiment where the defender may have the advantage of observing a prediction market on the aggressor s action the results of the experiments indicate that the use of prediction markets does not increase the defender s win rate prediction markets contain reliable information regarding aggressors decisions that is not being exploited by defenders and the existence of a prediction market does not alter the behavior of the aggressor whose behavior is being forecast

rational expectations and the aggregation of diverse information in laboratory security markets the idea that markets might aggregate and disseminate information and also resolve conflicts is central to the literature on decentralization hurwicz 1972 and rational expectations lucas 1972 we report on three series of experiments all of which were predicted to have performed identically by the theory of rational expectations in two of the three series one in which participants trade a complete set of arrow debreu securities and a second in which all participants have identical preferences double auction trading leads to efficient aggregation of diverse information and rational expectations equilibrium failure of the third series to exhibit such convergence demonstrates the importance of market institutions and trading instruments in achievement of equilibrium

pricing of electricity futures based on locational price differences the case of finland abstract we find that the pricing of finnish electricity market futures has been inefficient during the latest 10 years when the trading volumes of electricity price area differentials epads have more than doubled even though the calculated futures premium on epads is related to some risk measures and the variables capturing the demand and supply conditions in the spot electricity markets there has been a significant positive excess futures premium in the finnish market and financial market participants should have been able to utilize this also in economic terms this finding is new and relevant for the participants of the nordic electricity markets also in the future because both the speculative and hedging based trading is increasing in the nordic markets

the determinants of cross border equity flows abstract we explore a new panel data set on bilateral gross cross border equity flows between 14 countries 1989 1996 we show that a gravity model explains international transactions in financial assets at least as well as goods trade transactions gross transaction flows depend on market size in source and destination country as well as trading costs in which both information and the transaction technology play a role distance proxies some information costs and other variables explicitly represent information transmission an information asymmetry between domestic and foreign investors and the efficiency of transactions the geography of information is the main determinant of the pattern of international transactions while there is weak support in our data for the diversification motive once we control for the informational friction we broaden the scope of our results by presenting some evidence linking the results on equity transactions to equity holdings

electricity futures prices indirect storability expectations and risk premiums the goal of this paper is to examine to what extent electricity futures prices contain expected risk premiums or have power to forecast spot prices and whether this might be dependent on the type of electricity supply we analyse futures prices from the dutch market a market in which power is produced with storable fossil fuels and futures prices from the nordpool market where electricity is mostly produced by hydropower we show that futures prices from markets in which electricity is predominantly produced by imperfectly storable fuels such as hydro wind and solar contain information about expected changes in the spot price of electricity whereas futures prices from markets in which electricity is predominantly produced with perfectly storable fuels contain information about both expected price changes and time varying risk premiums these findings provide insight in the applicability of forward price models one cannot apply the same model to all electricity markets forward models for markets with imperfect indirect storability should depend heavily on price expectations and models should include time varying risk premiums for markets with perfect indirect storability

forward premia in electricity markets a replication study abstract motivated by mixed empirical evidence for the risk premium theory of bessembinder and lemmon 2002 i perform a replication study by rerunning simulations the risk premium theory links forward premia to the statistical properties of the anticipated distribution of spot power prices in an equilibrium approach my simulations closely following those run in the original paper support the first three hypotheses but not hypothesis 4 an increase in mean demand can thus result in a lower forward premium for some ranges of parameter values the replication results do not explain the mixed empirical support for the theory

wages and foreign ownership a comparative study of mexico venezuela and the united states abstract this paper explores the relationship between wages and foreign investment in mexico venezuela and the united states despite very different economic conditions and levels of development we find one fact that is robust across all three countries higher levels of foreign investment are associated with higher wages however in mexico and venezuela foreign investment is associated with higher wages only for foreign owned firms there is no evidence of wage spillovers leading to higher wages for domestic firms the lack of spillovers in mexico and venezuela is consistent with significant wage differentials between foreign and domestic enterprises in the united states where the evidence suggests some wage spillovers from foreign to domestic enterprises wage differentials are smaller

revisiting the relationship between spot and futures prices in the nord pool electricity market abstract this work discusses potential pitfalls of applying linear regression models for explaining the relationship between spot and futures prices in electricity markets in particular the bias coming from the simultaneity problem the effect of correlated measurement errors and the impact of seasonality on the regression results studying a 13 year long 1998 2010 price series of spot and futures prices at nord pool and employing regression models with garch residuals we show that the impact of the water reservoir level on the risk premium is positive which is to be expected but contradicts the results of botterud et al 2010 we also show that after taking into account the seasonality of the water level the storage cost theory proposed by botterud et al 2010 to explain the behavior of convenience yield has only limited support in the data

storage and the electricity forward premium we develop and test a model describing the influence of natural gas storage inventories on the electricity forward premium the model is constructed by linking the effect of gas storage constraints on the higher moments of the distribution of electricity prices to an established model of the effect of those moments on the forward premium the model predicts a sharply negative effect of gas storage inventories on the electricity forward premium when demand for electricity is high and space heating demand for gas is low empirical results based on pjm data strongly support the model

privatization political risk and stock market development in emerging economies this paper investigates whether privatization in emerging economies has a significant indirect effect on local stock market development through the resolution of political risk we argue that a sustained privatization program represents a major political test that gradually resolves uncertainty over political commitment to a market oriented policy as well as to regulatory and private property rights we present evidence suggesting that progress in privatization is indeed correlated with improvements in perceived political risk our analysis further shows that changes in political risk in general tend to have a strong effect on local stock market development and excess returns in emerging economies we conclude that the resolution of political risk resulting from successful privatization has been an important source for the rapid growth of stock markets in emerging economies

suckers are born but markets are made individual rationality arbitrage and market efficiency on an electronic futures market the iowa electronic markets are specially designed futures markets that appear to aggregate information efficiently to predict events such as election outcomes yet in theory perfect information aggregation is impossible further the markets are populated by a nonrepresentative sample of mistake prone and biased traders that is traders are prone to the behavioral anomalies predicted by behavioral finance how can this be reconciled with market efficiency here we take a first step by analyzing the behavior of two self selected types of traders dramatic differences in mistake rates across traders can help us answer the question market making traders who set prices are less mistake prone and appear to be more rational than price taking traders this highlights an important feature of markets marginal in this case market making not average traders set prices this can drive the efficiency of market prices in spite of large numbers of traders who display patently suboptimal behavior

market efficiency assessment under dual pricing rule for the turkish wholesale electricity market abstract this study analyses the price dynamics of day ahead and real time electricity prices following the implementation of dual pricing legislation in turkey to understand the legislation s impact on arbitrage opportunities and market efficiency the convergence of prices between the day ahead forward and the real time markets analysed in order to determine whether persistent price differences between the two markets exist arbitrage opportunities exist if there is a persistent difference between prices in the day ahead forward and real time market markets are considered to be efficient if it is not possible for market participants to earn an excess profit through exploitation of price differences furthermore we examined how the ex post risk premium changes over time using rolling estimations and find that after the implementation of dual pricing the risk premium increased significantly for day and peak hours where the demand is relatively higher compared to night hours as market participants have more experience regarding the dynamics of the market the difference between real time and day ahead forward prices converges to zero since the dual pricing regime enforce market participants to forecast accurately by punishing the forecast error

information aggregation and manipulation in an experimental market prediction markets are increasingly being considered as methods for gathering summarizing and aggregating diffuse information by governments and businesses alike critics worry that these markets are susceptible to price manipulation by agents who wish to distort decision making we study the effect of manipulators on an experimental market we find that manipulators are unable to distort price accuracy subjects without manipulation incentives compensate for the bias in offers from manipulators by setting a different threshold at which they are willing to accept trades

reversal of fortunes democratic institutions and foreign direct investment inflows to developing countries does increased democracy promote or jeopardize foreign direct investment fdi inflows to less developed countries we argue that democratic institutions have conflicting effects on fdi inflows on the one hand democratic institutions hinder fdi inflows by limiting the oligopolistic or monopolistic behaviors of multinational enterprises facilitating indigenous businesses pursuit of protection from foreign capital and constraining host governments ability to offer generous financial and fiscal incentives to foreign investors on the other hand democratic institutions promote fdi inflows because they tend to ensure more credible property rights protection reducing risks and transaction costs for foreign investors hence the net effect of democracy on fdi inflows is contingent on the relative strength of these two competing forces our argument reconciles conflicting theoretical expectations in the existing literature empirical analyses of fifty three developing countries from 1982 to 1995 substantiate our claims we find that both property rights protection and democracy related property rights protection encourage fdi inflows after controlling for their positive effect through property rights protection democratic institutions reduce fdi inflows these results are robust against alternative model specifications statistical estimators and variable measurements

aggregation and manipulation in prediction markets effects of trading mechanism and information distribution we conduct laboratory experiments on variants of market scoring rule prediction markets under different information distribution patterns to evaluate the efficiency and speed of information aggregation as well as test recent theoretical results on manipulative behavior by traders we find that markets structured to have a fixed sequence of trades exhibit greater accuracy of information aggregation than the typical form that has unstructured trade in comparing two commonly used mechanisms we find no significant difference between the performance of the direct probability report form and the indirect security trading form of the market scoring rule in the case of the markets with a structured order we find evidence supporting the theoretical prediction that information aggregation is slower when information is complementary in structured markets the theoretical prediction that there will be more delayed trading in complementary markets is supported but we find no support for the prediction that there will be more bluffing in complementary markets however the theoretical predictions are not borne out in the unstructured markets this paper was accepted by brad barber teck ho and terrance odean special issue editors

the informational efficiency of experimental asset markets a fundamental difficulty in devising any test of general efficient market hypotheses is the specification of the relevant public and private information sets of traders without a consensus as to reasonable empirical specifications tests of the hypotheses remain minimal or controversial in this study we examine the efficiency of experimental asset markets in which one may unambiguously identify the public and private information sets of traders we focus on how market efficiency is affected by the presence of futures markets in settings that incorporate different types of uncertainty and inside information our experimental results support four conclusions 1 market outcomes tend to evolve toward strong form informationally efficient equilibria whether or not futures markets and or event uncertainty are present 2 the presence of futures markets clearly stabilizes spot prices 3 the presence of futures markets tends to speed the evolution of asset markets to more efficient equilibria where there

investor protection and corporate governance recent research has documented large differences among countries in ownership concentration in publicly traded firms in the breadth and depth of capital markets in dividend policies and in the access of firms to external finance a common element to the explanations of these differences is how well investors both shareholders and creditors are protected by law from expropriation by the managers and controlling shareholders of firms we describe the differences in laws and the effectiveness of their enforcement across countries discuss the possible origins of these differences summarize their consequences and assess potential strategies of corporate governance reform we argue that the legal approach is a more fruitful way to understand corporate governance and its reform than the conventional distinction between bank centered and market centered financial systems

a collection of surveys on market experiments this paper highlights the contributions in this special issue to the very large and rapidly growing research on experimental markets it contains ten surveys of different streams of research in this area including asset markets contests environmental policy frictions general equilibrium labor markets multi unit auctions oligopoly markets and prediction markets

an options pricing approach to ramping rate restrictions at hydro power plants this paper investigates the impact of ramping rate restrictions imposed on hydro operations to protect aquatic ecosystems the optimal ramping decision is specified as an optimal control problem which results in a hamilton jacobi bellman hjb equation electricity prices are modelled as a regime switching stochastic process the optimal control is determined by solving the hjb equation numerically using a fully implicit finite difference approach with semi lagrangian time stepping the paper focuses on the effect of ramping restrictions on a hydro plant s value and optimal operations and provides an analysis of which factors cause ramping restrictions to have a greater or lesser impact on profitability it is shown that hydro plant value is negatively affected by ramping restrictions but the extent of the impact depends on key parameters which determine the desirability of frequent changes in water release rates interestingly for the case considered value is not sensitive to ramping restrictions over a large range of restrictions the results point to the importance of accurately modelling electricity prices in gauging the trade offs involved in imposing restrictions on hydro operators which may hinder their ability to respond to volatile electricity prices and meet peak demands

estimating the commodity market price of risk for energy prices the purpose of this paper is to estimate the market price of risk mpr for energy commodities the ratio of expected return to standard deviation the mpr sign determines whether energy forward prices are upward or downward biased predictors of expected spot prices we estimate mprs using spot and futures prices while accounting for the samuelson effect we find long term mprs generally positive and short term negative consistent with positive energy betas and hedging respectively in spot electricity markets mprs in day ahead prices agree with short dated futures our results relate risk premia to informed hedging decisions and futures prices to forecast expected prices

host country reforms and fdi inflows how much difference do they make summary this study examines the effects of various policies on foreign direct investment fdi flows from the perspective of the eclectic theory of international investment and hence the advantages of foreign ownership host country location and internationalization host country policies can influence fdi flows primarily through their influence on the advantages of location in the host country pooled cross section and time series data for 49 less developed countries ldcs over 1970 95 are used to examine the effects of several different types of policy institutional variables including corporate tax rates tariff rates the degree of openness to international capital flows exchange rate distortions contract enforcement nationalization risk bureaucratic delay and corruption a multivariate analysis of the effects on fdi flows of each type of policy with and without controls for other relevant determinants is conducted two different sources of fdi data are employed as well as two different measures of capital controls although there are methodological problems in estimation and especially collinearity problems and relatively severe availability constraints for some of the relevant measures the results demonstrate the relevance and importance for fdi flows of many of the policy institutional variables under study they also indicate that the results from panel methods yield results that differ rather significantly from those obtained from pure cross section analysis because of complementarity between the various elements of a healthy investment climate the effects of some policy reforms estimated from models which do not control for changes in other policies may overstate the effectiveness of individual policy reforms

the financial and operating performance of privatized firms during the 1990s this study compares the pre and postprivatization financial and operating performance of 85 companies from 28 industrialized countries that were privatized through public share offerings for the period from 1990 through 1996 we document significant increases in profitability output operating efficiency and dividend payments and significant decreases in leverage ratios for our full sample of firms after privatization and for most subsamples examined capital expenditures increase significantly in absolute terms but not relative to sales employment declines but insignificantly combined with results from two previous directly comparable studies these findings strongly suggest that privatization yields significant performance improvements during the past two decades the privatization of state owned enterprises has moved from being a radical almost desperate policy initiative of the thatcher government in britain to being an accepted economic policy for governments of all ideological stripes according to gibbon 1998 860 billion has been raised by governments worldwide through privatizations with the bulk of this total coming since 1987 and at least one commentator roche 1996 predicts that no less than 6 trillion will be raised through privatizations over the next two decades in 1997 alone sales of public enterprises totaled a record 161 billion worldwide with more than 110 billion of the total coming during the second half of the year and 1998 s total of almost 140 billion indicates that the pace shows no sign of slackening as we approach a new millennium

the pecking order of cross border investment abstract is there a pecking order of cross border investment in that countries become financially integrated through some types of investment rather than others using a novel database of bilateral capital stocks for all types of investment fdi portfolio equity securities debt securities as well as loans for a broad set of 77 countries we show that such a pecking order indeed exists the paper focuses on two key determinants of this pecking order information frictions and the quality of host country institutions overall we find that in particular fdi and to some extent also loans are substantially more sensitive to information frictions than investment in portfolio equity and debt securities we also show that the share as well as the size of fdi that a country receive are largely insensitive to institutional factors in host countries while portfolio investment is by far the most sensitive to the quality of institutions this provides new evidence in favor of some hypotheses but contradicts others put forward in the literature on trade in financial assets

wishes expectations and actions a survey on price formation in election stock markets abstract with error prone and biased individual traders can markets aggregate trader information and produce efficient outcomes we review election stock market evidence that suggests this does happen individual traders appear biased and error prone consistently yet these markets prove quite efficient in predicting election outcomes we also review work which documents comparable but substantially different phenomena in related laboratory markets in addition we report the results from a new laboratory session which shows how we can create particular biases that mirror those in election stock markets finally we discuss how combined laboratory and field experiments can help us understand trader market interactions

the performance of privatized firms in the czech republic abstract with the growing importance of privatizations as a part of government policy most empirical studies of these privatizations conclude that firm performance immediately improves following privatization privatization has been the most important part of the transition from the centrally planned economies of central and eastern europe and has a larger impact on those economies than privatizations in other countries however few studies have looked at the performance of firms following mass privatization this study uses 453 separate firms 101 firms privatized in both waves for a total of 554 observations in the first and second waves of czech voucher privatization using methodology from previous studies we find that while the overall effects from privatization are positive the effects vary by privatization wave size and industry firms privatized in the first wave performed worse decline in performance following privatization than firms privatized in the second wave we also fail to find ownership concentration or debt as an important factor in restructuring the firm i believe that the results are consistent with two hypotheses first economic and political structure surrounding the privatization waves plays an important part in the success of privatization stable environments both political and economic help privatized firms restructure and improve operating performance as well as attract foreign investors and capital even in less developed countries but in transitional economies undergoing mass privatization in rapidly changing and developing economic and political environments hinder firms from restructuring and improving performance following privatization results are also consistent with the hypothesis that firms with a longer preparation period prior to privatization an implicit seasoning improve performance following privatization

market efficiency and risk premia in short term forward prices abstract using recursive estimation and rolling windows over extended sample periods we examine the time varying relationship between spot and short term forward prices in the pennsylvania new jersey maryland pjm wholesale electricity market we examine theoretical models of forward risk premia in electricity markets and show that recent data do not provide support for existing models the results indicate that short term forward prices have converged towards unbiased predictors of the subsequent spot prices

market price of risk implied by asian style electricity options and futures in this paper we propose a jump diffusion type model which recovers the main characteristics of electricity spot price dynamics in the nordic market including seasonality mean reversion and spiky behavior we show how the calibration of the market price of risk to actively traded futures contracts allows for efficient valuation of nord pool s asian style options written on the spot electricity price furthermore we study the evolution of the market price of risk and the risk premium over a three year time period and compare the obtained results with those reported in the literature

efficiency of experimental security markets with insider information an application of rational expectations models the study reports on the ability of competing models of market information integration and dissemination to explain the behavior of simple laboratory markets for a one priced security returns to the security depended upon a randomly drawn state of nature some agents insiders whose identity was unknown to other agents knew the state before the markets opened with replication of market conditions the predictions of a fully revealing rational expectations model are relatively accurate prices adjusted immediately to near rational expectations prices profits of insiders were virtually indistinguishable from non insiders and efficiency levels converged to near 100 percent

in accuracy of a european political stock market the influence of common value structures this paper presents the results of a political stock market in the netherlands pam94 the exchange covered three consecutive elections allowing trade on five different markets the predictions at pam94 appear to be less accurate than those of previous markets of comparable size of the possible explanations that we examine one in particular survives closer scrutiny it concerns a type of judgement failure related to the winner s curse in common value auctions theoretical as well as empirical support is offered apart from qualifying the attractiveness of such markets as an alternative for opinion polls this explanation may also be relevant for the analysis of other asset markets moreover this judgement failure may be more important for european political stock markets than for the u s because the structure of the common values vote shares at multiparty elections make them especially vulnerable to it

how much information is incorporated in financial asset prices experimental evidence we propose a new estimation method and use experimental data from multiple double auction experiments in the literature to directly estimate how much information is incorporated in financial market prices we find that public information is almost completely reflected in prices but that surprisingly little private information less than 50 is incorporated in prices our estimates therefore suggest that while semi strong informational efficiency is consistent with the data financial market prices may be very far from strong form efficiency we compare our estimates with beliefs of economists surveyed at the econometric society meetings and find that economists and finance researchers alike expect market prices to reflect considerably more private information than what we estimated

a theory of privatisation public enterprises around the world have proved to be highly inefficient primarily because they pursue strategies such as excess employment that satisfy the political objectives of politicians who control them privatization of public enterprises can raise the cost to politicians of influencing them since subsidies to private firms necessary to force them to remain inefficient are politically harder to sustain than wasted profits of the state firms in this way privatization leads to efficient restructuring of firms moreover privatization is more effective when combined with a tight monetary policy and when the new owners of firms are profit maximizing investors rather than their employees or even managers copyright 1996 by royal economic society

a space time random field model for electricity forward prices abstract stochastic models for forward electricity prices are of great relevance nowadays given the major structural changes in the market due to the increase of renewable energy in the production mix in this study we derive a spatio temporal dynamical model based on the heath jarrow morton hjm approach under the musiela parametrization which ensures an arbitrage free model for electricity forward prices the model is fitted to a unique data set of historical price forward curves as a particular feature of the model we disentangle the temporal from spatial maturity effects on the dynamics of forward prices and shed light on the statistical properties of risk premia of the noise volatility term structure and of the spatio temporal noise correlation structures we find that the short term risk premia oscillates around zero but becomes negative in the long run we identify the samuelson effect in the volatility term structure and volatility bumps explained by market fundamentals furthermore we find evidence for coloured noise and correlated residuals which we model by a hilbert space valued normal inverse gaussian levy process with a suitable covariance functional

price conveyed information versus observed insider behavior a note on rational expectations convergence in a recent paper on behavior in experimental securities markets plott and sunder 1982 concluded that the rational expectations re model was superior to the traditional prior information pl model in predicting equilibrium prices and holdings in particular given a market with one commodity three possible states of the world and three groups of trader types each with differing valuations on the commodity per state initially uninformed traders were able to infer the underlying state from the current market price and act accordingly in a related paper friedman harrison and salmon 1984 observed that given the existence of a futures market the re model outperformed the pi model in multiperiod single commodity markets as well one source of potential misinterpretation however comes from the fact that although one half of the traders of each type were informed of the true state at the beginning of each period in plott and sunder 1982 and one third of the traders of each type in friedman harrison and salmon 1984 the same traders were informed in almost every period in a more recent paper plott and sunder 1983 constructed markets where all traders received partial information i e given possible states x y and z a trader s private information would be either not x or not y if the state were z yet the combinations of traders receiving a certain message in any period were determined randomly

the relationship between spot and futures prices in the nord pool electricity market abstract we analyze 11 years of historical spot and futures prices from the hydro dominated nord pool electricity market we find that futures prices tend to be higher than spot prices the average convenience yield is therefore negative but varies by season and depends on the storage levels in hydro reservoirs the average realized return on holding a long position in the futures market is also negative the negative convenience yield and risk premium contrast empirical findings in most other commodity markets we argue that differences between the supply and demand sides in terms of risk preferences and the ability to take advantage of short term price variations can contribute to explain the observed relationship between spot and futures prices in addition our analysis shows that the relationship between spot and futures prices is clearly linked to the physical state of the system such as hydro inflow reservoir levels and demand

historical presidential betting markets this paper analyzes the large and often well organized markets for betting on u s presidential elections that operated between 1868 and 1940 four main points are addressed first we show that the market did a remarkable job forecasting elections in an era before scientific polling second the market was fairly efficient despite the limited information of participants and active attempts to manipulate the odds third we argue political betting markets disappeared largely because of the rise of scientific polls and the increasing availability of other forms of gambling finally we discuss lessons this experience provides for the present

pricing of monthly forward contracts in the nord pool market this paper investigates whether the pricing of forward contracts in the nord pool market is efficient monthly forward contracts were introduced in the nord pool market in 2003 likewise quarterly contracts that will replace seasonal contracts were introduced in 2004 for a transition period these contracts together with the pre existing seasonal and yearly contracts constitute the forward market in an efficient forward market the price of a seasonal forward contract should equal the time weighted average of the underlying monthly forward contracts in this paper we use historic forward price information to evaluate whether this relationship holds true and find that there are inefficiencies in the pricing

information mirages in experimental asset markets one explanation for the apparent volatility of asset prices is that people overreact to trades that are uninformative creating self generated information mirages the authors test whether mirages occur in experimental asset markets there are insiders in only half the periods so traders cannot be sure if the trades of others reveal information the authors observed four clear mirages in forty seven periods without insiders mirages always occurred early in an experimental session in later periods traders learn whether there are insiders by observing nonprice information such as the speed of trading and mirages occurred only temporarily copyright 1991 by university of chicago press

governance infrastructure and us foreign direct investment this paper examines the statistical importance of governance infrastructure as a determinant of us foreign direct investment fdi in broad terms governance infrastructure represents attributes of legislation regulation and legal systems that condition freedom of transacting security of property rights and transparency of government and legal processes our econometric analysis uses a two stage estimation procedure in the first stage the probability that a country is an fdi recipient is estimated the results indicate that countries that fail to achieve a minimum threshold of effective governance are unlikely to receive any us fdi countries that receive no us fdi are typically countries that do not promote free and transparent markets that have ineffective governments and that often have legal systems that are not rooted in english common law in the second stage the analysis is restricted to those countries that did receive fdi flows the estimated equations focus on the determinants of the amount of fdi received given that a country is a recipient of us fdi governance infrastructure including the nature of the legal system is an important determinant of the amount received

inequality and institutions abstract this paper presents theory and evidence on the relationship between inequality and institutional quality we exhibit a model in which the two may dynamically reinforce each other and set to test this relationship with a broad array of institutional measures the double causality between institutional strength and a more equal distribution of income is empirically established using dynamic panel and linear feedback analysis

prediction markets in the laboratory prediction markets are becoming an ever more popular method for aggregating disparate information companies use prediction markets to forecast sales release dates and other internal activities recently several well known economists have argued that government ought to eliminate impediments to unleashing the power of prediction markets broadly this survey paper looks at the laboratory experiments which provide part of the scientific justification for using prediction markets these systems work because people who have private knowledge can use this insider information in the market but doing so causes the price to reflect these data starting with early experiments that show markets can under certain circumstances aggregate information we discuss the robustness of prediction markets to various design features we also discuss places where performance does not match rhetoric and briefly look at experimental comparisons of alternative information aggregating institutions another issue consistently raised regarding the implementation of prediction markets is the degree to which traders can manipulate prices and thus the information gleaned by following a series of experiments on manipulation we present the circumstances that are and are not sufficient for manipulation attempts to be successful finally we offer suggestions on where we believe future experiments are needed in this area

international investment location decisions abstract in international location tournaments governments compete for foreign investment with tax and other short run incentives such tournaments can be won if agglomeration economies are sufficiently powerful to overcome investors desire to spread investments as a hedge against risk we focus on manufacturing investments by u s multinationals in the 1980s our econometric results suggest that agglomeration economies are indeed the dominant influence on investor calculations paradoxically short run incentives have limited apparent impact on location choice we conclude that high cost tournament play is unnecessary for countries with good infrastructure development specialized input suppliers and an expanding domestic market

determinants of hedging and risk premia in commodity futures markets this paper examines the determinants of commodity futures hedging and of risk premia arising from covariation of the futures price with stock market returns and with the reve nues of producers owing to supply shocks that stochastically redistribute real wealth surplus between producers and consumers and to limited participation in the futures market the total risk premium in the model is not proportional to the contract s covariance with aggregate consumption stock market variability interacts with the incentive to hedge causing the producer hedging component of the risk premium to increase de crease with income elasticity for a normal inferior good production costs that depend on output raise the premium we argue that output and demand shocks will typically be positively correlated raising the premium high supply elasticity reduces the absolute heding premium by reducing the variability of spot price and revenue

information and efficiency in political stock markets using computerized markets to predict election results this study concentrates on four computerized political markets in germany between 1990 and 1998 while this new method for the prediction of election events worked quite well in the usa it did not perform as well in germany searching for the causes of this distinction it is shown that in contrast to the findings of forsythe et al 1992 i extraordinary profits were achieved less by people who took advantage of other people s anomalies than by those people who acquired an advantage from the existence of asymmetric information ii the marginal trader hypothesis does not hold when applied to german markets and that iii traders relied on public opinion polls it is argued that these distinctions are caused by the differences in the german and the us voting systems additionally it is shown that to a certain extent iv election markets were able to predict the contemporary mood of the electorate without the help of public opinion polls v first of all the informed traders used public opinion pol
