reform of the coal sector in an open economy the case of china cheap abundant and easy to transport and store coal has been produced and consumed to meet people s energy needs the last decade s growth in global coal use has been driven mainly by developing economies like china whose phenomenal economic growth has been powered by coal fired electricity and promoted by the export of manufactured goods a recent reform focus in china s coal sector is on coal taxation the paper develops a game theoretic model tailored to the context of china where coal taxation reform takes place against the background of privatisation of coal firms and an open economy it finds that the adoption of special coal taxes is optimal for social welfare under most circumstances but may induce coal firms to commit opportunistic behaviour in the process of privatisation the paper also cautions about potential resistance to the reform from consumers coal firms and government officials

interest rate volatility and the term structure a two factor general equilibrium model we develop a two factor general equilibrium model of the term structure the factors are the short term interest rate and the volatility of the short term interest rate we derive closed form expressions for discount bonds and study the properties of the term structure implied by the model the dependence of yields on volatility allows the model to capture many observed properties of the term structure we also derive closed form expressions for discount bond options we use hansen s generalized method of moments framework to test the cross sectional restrictions imposed by the model the tests support the two factor model there are essentially two approaches to the modeling of the term structure of interest rates in continuous time the equilibrium approach pioneered by

divided we reform evidence from us welfare policies abstract divided government is often thought of as causing legislative deadlock i investigate the link between divided government and economic reforms using a novel data set on welfare reforms in us states between 1978 and 2010 panel data regressions show that under divided government a us state is around 25 more likely to adopt a welfare reform than under unified government several robustness checks confirm this counter intuitive finding case study evidence suggests an explanation based on policy competition between governor senate and house

dynamics of credit spread moments of european corporate bond indexes abstract traditional quantitative credit risk models assume that changes in credit spreads are normally distributed but empirical evidence shows that they are likely to be skewed fat tailed and change behaviour over time not taking into account such characteristics can compromise calculation of loss probabilities pricing of credit derivatives and profitability of trading strategies therefore the aim of this study is to investigate the dynamics of higher moments of changes in credit spreads of european corporate bond indexes using extensions of garch type models that allow for time varying volatility skewness and kurtosis of changes in credit spreads as well as a regime switching garch model which allows for regime shifts in the volatility of changes in credit spreads performance evaluation methods are used to assess which model captures the dynamics of observed distribution of the changes in credit spreads produces superior volatility forecasts and value at risk estimates and yields profitable trading strategies the results presented can have significant implications for risk management trading activities and pricing of credit derivatives

a political economy approach to the neoclassical gradualist model of transition a political economy approach to the neoclassical gradualist model of transition requires the exposition of what i define the primary elements of the model which are economic analysis definition of a good society speed political structure ideological structure and whether the initial conditions were incorporated in the model after the identification of the primary elements of the neoclassical gradualist model the next step is to identify secondary elements the desired changes with respect to price liberalization stabilization privatization institutional structure monetary policy and the financial system fiscal policy international trade and foreign aid and social policy the analytical framework developed makes possible to understand the neoclassical gradualist model from a new and more enlightening perspective we are better able to comprehend the complexities involved and the disagreements about the reform process the adoption of a gradual process of transition did not only involve specifying the required policies of a successful transition but also entailed a process a sequence by which the reforms should be introduced as such a process of transition consistent with the policies recommended by the neoclassical gradualists economists is developed the conclusion reveals the inconsistencies in the model copyright blackwell publishers ltd 2005

learning from the doers developing country lessons for advanced economy growth from 1980 to 1992 emerging and developing countries grew by 3 4 percent per year their annual rate of growth increased to 5 4 percent between 1993 and 2012 no such increase occurred for advanced nations whose average growth from 1980 to 2012 was roughly constant excluding the impact of the 2008 2009 recession developing nations turned themselves around by embracing discipline sustained commitment to a pragmatic and flexible growth strategy three illustrations of discipline through the lens of trade fiscal and debt reforms in the developing world offer relevant practical lessons for recovery in advanced economies and continued catch up growth in developing nations

the causal effect of mortgage refinancing on interest rate volatility empirical evidence and theoretical implications this article investigates the effects of mortgage backed security mbs hedging activity on interest rate volatility and proposes a model that takes these effects into account an empirical examination suggests that the inclusion of information about mbss considerably improves model performance in pricing interest rate options and in forecasting future interest rate volatility the empirical results are consistent with the hypothesis that mbs hedging affects the interest rate volatility implied by both options and the actual interest rate volatility the results also indicate that the inclusion of information about the mbs universe may result in models that better describe the price of fixed income securities

on the reversibility of structural reforms abstract what are the factors that explain reversals in the implementation of structural reforms our main hypothesis is that reversals in different reforms are driven by different factors this paper presents novel evidence showing that a fdi inflows reduce the likelihood of privatization reversals b worsened terms of trade increase the probability of external liberalization reversals and c labor strikes propel reversals in price liberalization

ex post analysis of economic impacts from wind power development in u s counties wind power development has surged in recent years in the united states policymakers and economic development practitioners to date have typically relied upon project level case studies or modeled input output estimates to assess the economic development impacts from wind power often focusing on potential local state wide or national employment or earnings impacts building on this literature we conduct an ex post econometric analysis of the county level economic development impacts of wind power installations from 2000 through 2008 in a large wind rich region in the country taking into account factors influencing wind turbine location we find an aggregate increase in county level personal income and employment of approximately 11 000 and 0 5 jobs per megawatt of wind power capacity installed over the sample period of 2000 to 2008 these estimates appear broadly consistent with modeled input output results and translate to a median increase in total county personal income and employment of 0 2 and 0 4 for counties with installed wind power over the same period

institutions and performance in european labour markets taking a fresh look at evidence this paper presents a selective survey of the recent literature on labour market institutions and offers new empirical eu based evidence on the impact of labour market reforms on employment and labour market adjustment although the literature traditionally treats labour market institutions as exogenous attention shifted recently towards understanding the underlying causes of specific institutional arrangements as a consequence the literature highlights the great importance of an efficient policy design exploiting these interactions wisely and identifies general principles for achieving an efficient policy design at both macro and micro levels although empirical evidence does not show a major change in terms of intensity of labour market reform after the setting of the economic and monetary union and the creation of the euro the reforms aiming at strengthening the labour market attachment of vulnerable groups tend to have been successful both in raising their employment and increasing labour market adjustment

the political economy of restructuring and privatization in eastern europe this paper reports some of the recent research in the political economy of transition in central and eastern europe with special emphasis on restructuring and privatization this line of research is concerned with the political feasibility of reform packages and the effect of political constraints on the design of reforms political constraints appear to play a major role in economic transition 2 in poland transition started with a homogeneous solidarity led government enjoying great legitimacy l balcerowicz the finance minister who had launched reform in january 1990 had however to leave office and part of his policies are now being reversed parliament is fragmented government duration is becoming increasingly short workers are striking against privatization plans czechoslovakia is breaking up partly because the slovak population is not ready to follow the rhythm of reforms initiated by v klaus in prague the support for e gai dar s transition program in russia has dwindled among the population conservative forces are gathering momentum alarming neonazi manifestations in east germany are an indicator of the low tolerance of the population for the changes imposed on them some countries are doing better hungary is doing comparatively well with a more stable political situation and relative successes in reforms allowing it to attract foreign direct investment china is experiencing a rapid expansion of the non state sector and smooth advances in the reform process in a context of sustained economic growth qian and xu 1992 these two countries

success and failure of reform insights from the transition of agriculture this paper analyzes the linkages between the reform strategies in transition countries and economic performance the authors focus on agriculture because of the sharpness of the policy changes fundamental differences among countries and relative simplicity of agricultural relationships the authors document post reform performance in the transition countries of asia and europe the authors show how a pricing reform and subsidy reductions b land rights reform and policies that affect farm restructuring and c the presence institutions that facilitate exchange either markets or market substitutes affect output and productivity the paper ends with general lessons on reforms and transition

the effect of the production tax credit on wind energy production in deregulated electricity markets abstract this letter estimates the asymmetric influence of the production tax credit on wind energy production i find that states with deregulated electricity markets were more responsive to the tax incentive than their regulated counterparts excluding any external benefits from wind production this dissimilarity amounts to a monthly difference of up to 464 450 in federal benefits

asset pricing under the quadratic class we identify and characterize a class of term structure models where bond yields are quadratic functions of the state vector we label this class the quadratic class and aim to lay a solid theoretical foundation for its future empirical application we consider asset pricing in general and derivative pricing in particular under the quadratic class we provide two general transform methods in pricing a wide variety of fixed income derivatives in closed or semi closed form we further illustrate how the quadratic model and the transform methods can be applied to more general settings i introduction we identify and characterize a class of term structure models where bond yields are quadratic functions of the markov process we label this class the quadratic class and aim to lay a solid theoretical foundation for its future empirical application we identify the necessary and sufficient conditions for the quadratic class and consider the general asset pricing problem under the quadratic framework in particular we propose two transform methods to price a wide variety of interest rate derivatives in closed or semi closed form we further illustrate how the pricing methods can be applied to more general settings examples include option pricing for currencies or stocks with quadratic stochastic volatilities our interests in the quadratic class come mainly from concerns on empirical application recent empirical research within the affine framework of duffie and kan 1996 indicates an inherent tension between i delivering good empirical performance in matching salient features of the interest rate data and ii excluding positive probabilities of having negative interest rates for example backus telmer and wu 1999 and dai and singleton 2000 find that incorporating gaussian state variables in the affine framework significantly increases the flexibility for model design and greatly improves its empirical performance in capturing the conditional dynamics of interest rates dai and singleton 2001

what explains the success or failure of structural adjustment programs in the 1980s development assistance shifted largely from financing investments such as roads and dams to promoting policy reform this change came because of a growing awareness that developing countries were held back more by poor policies than by a lack of finance for investment after nearly 20 years experience with policy based or conditional lending there have now been many studies of adjustment lending most of which take a case study approach many conclude that policy based lending works if countries have decided on their own to reform the authors examine a database of 220 world bank supported reform programs to identify why adjustment programs succeed or fail they find that a few political economy variables can successfully predict the outcome of an adjustment loan 75 percent of the time variables under the world bank s control resources devoted to preparation and supervision or number of conditions have no relationship with an adjustment program s success or failure what development agencies must do then is select promising candidates for adjustment support when the candidates is a poor selection devoting more administrative resources or imposing more conditions will not increase the likelihood of successful reform to improve its success rate with adjustment lending the world bank must become more selective and do a better job of understanding which environments are promising for reform and which are not that is likely to lead to fewer adjustment loans unless there is a significant change in the number of promising reformers to become more effective at supporting policy reform the agency must be willing to accept that this may lead to smaller volumes of lending

explorations into factors explaining money market returns in this article we measure and interpret the common factors that describe money market returns results are presented for both three and four factor models we find that the three factor model explains on average 86 percent of the total variation in most money market returns while the four factor model explains on average 90 percent of this variation using mimicking portfolios we provide an interpretation of the systematic risks represented by these factors in this article we attempt to measure and interpret the common factors that describe money market returns the factor approach we employ assumes that the covariance matrix of a set of random variables in this case excess returns can be decomposed into common or systematic components and idiosyncratic or nonsystematic components this decomposition into systematic and nonsystematic components is based on an assumption of a linear relationship between the returns of each security and a set of common factors this is the assumption of linear return generating models which form an integral part of the structure of many asset pricing theories for example arbitrage pricing theory apt as developed by ross 1976 the interpretation is that the common factors represent sources of systematic or nondiversifiable risk and the idiosyncratic component of returns represents diversifiable risks our focus here is not on testing a particular asset pricing model per se but on developing empirical evidence for the existence of stylized facts regarding money market returns the stylized facts take the form of the existence measurement and interpretation of the common factors that are found in money markets our attempt to measure and interpret these sources of systematic risk may eventually lead to the construction of observable eco

another look at models of the short term interest rate the short term rate of interest is fundamental to much of theoretical and empirical finance yet no consensus has emerged on the dynamics of its volatility we show that models which parameterize volatility only as a function of interest rate levels tend to over emphasize the sensitivity of volatility to levels and fail to model adequately the serial correlation in condi tional variances on the other hand serial correlation based models like garch models fail to capture adequately the relationship between interest rate levels and volatility we introduce and test a new class of models for the dynamics of short term interest rate volatility which allows volatility to depend on both interest rate levels and information shocks two important conclusions emerge first the sensitivity of interest rate volatility to interest rate levels has been overstated in the literature while this relationship is important adequately modeling volatility as a function of unexpected information shocks is also important sec ond we conclude that the volatility processes in many existing theoretical models of interest rates are misspecified and suggest new paths toward improving the theory

the imf s unmet challenges the international monetary fund is a controversial institution whose interventions regularly provoke passionate reactions we will argue that there is an important role for the imf in helping to solve information commitment and coordination problems with significant implications for the stability of national economies and the international monetary and financial system in executing these functions the effectiveness of the imf like that of a football referee depends on whether the players see it as competent and impartial we will argue that the fund s perceived competence and impartiality and hence its effectiveness are limited by its failure to meet four challenges concerning the quality of its surveillance of individual countries groups of countries and the global system the relevance of conditionality in loan contracts the utility of the fund s approach to debt problems and the fund s failure to adopt a system of governance that gives appropriate voice to different stakeholders these problems of legitimacy will have to be addressed in order for the imf to play a more effective role in the 21st century

advertising and limit pricing we enrich milgrom and roberts 1982 limit pricing model to allow an incumbent to signal his costs with both price and advertisements our fundamental result is that a cost reducing distortion occurs in that the incumbent behaves as if there were complete information but his costs were lower than they are preentry price is therefore distorted downward and demand enhancing advertising is distorted upward as a consequence of signalling if advertising is a purely dissipative signal it is not used nor therefore distorted recent refinements of the sequential equilibrium concept are featured

the stochastic volatility of short term interest rates some international evidence this paper estimates a stochastic volatility model of short term riskless interest rate dynamics estimated interest rate dynamics are broadly similar across a number of countries and reliable evidence of stochastic volatility is found throughout in contrast to stock returns interest rate volatility exhibits faster meanreverting behavior and innovations in interest rate volatility are negligibly correlated with innovations in interest rates the less persistent behavior of interest rate volatility reflects the fact that interest rate dynamics are impacted by transient economic shocks such as central bank announcements and other macroeconomic news the past decade has witnessed unprecedented growth in the market for fixedincome derivatives domestically as well as internationally in light of this growth recent research has attempted to empirically characterize the dynamics of short term riskless interest rates necessary for the valuation of many of these securities with few exceptions much of this evidence has been concerned with the behavior of u s interest rates the purpose of this paper is to investigate the dynamics of short term interest rates across a number of countries a particularly noteworthy feature at least of the u s evidence is that the volatility of short term interest rates is itself volatile the stochastic nature of volatility is an important property of interest rate dynamics which we wish to focus on in our comparison to do so practically this paper implements a computationally efficient and statistically reliable method for estimating stochastic volatility models in finance we apply this method to chan et al s 1992 specification of short term riskless interest rate dynamics augmented with stochastic volatility for a clean international comparison we use proxies for short term riskless interest rates drawn from the same market the london interbank market over the same sample period unlike nowman 1997 we find that the

international organizations and the political economy of reforms abstract we develop a simple dynamic model of policy reform that captures some of the determinants that underlie the differences between the reform paths taken by a number of countries since the early 1990s the model focuses on the interaction between domestic institutions and international organizations that promote reform on the one hand and the political incentives for reversing reforms on the other at equilibrium there are three types of reform paths a country can undergo a full scale lasting reform can carry out a partial but lasting reform or can go through cycles of reforms and costly counter reforms domestic institutions along with the incentives provided by international organizations determine the equilibrium path a politically myopic international organization may induce cycles of reforms and costly counter reforms thereby reducing the country s well being an international organization that only provides funds to promote reforms may have a less beneficial effect than one that assists the country with fresh funds to defend reforms when there is a risk of reversal international funds that promote reforms can also influence domestic institutions for example due to the intervention of an international organization countries could have incentives to dismantle institutions that build up reversal cost and or do not fully build their fiscal capacity

managerial career concerns privatization and restructuring in transition economies abstract we set up a dynamic adverse selection model to explain how career concerns may induce managers in state owned enterprises soes to restructure their firms it is shown how government monopsony power over managers led to the ratchet effect under a socialist economy even under reforms coming short of privatization the introduction of a managerial labour market through privatization introduces competition for managers and eliminates the ratchet effect thereby inducing managers to restructure the model is consistent with the empirical evidence of soes restructuring in transition economies

compensations as signaling devices in the political economy of reforms we propose an explanation for why efficient reforms are not carried out when losers can block their implementation and compensations are feasible in our model a government tries to sequentially implement two efficient reforms by bargaining with interest groups the organization of interest groups is endogenous compensations are distortionary and different governments care differently about distortions governments use low compensations to discourage losers who just want to receive transfers from organizing this comes at the cost of reforms being blocked by interest groups with relatively high losses resulting in a bias against payment of compensations and the implementation of reforms

gradual green tax reforms abstract green tax reforms have become an important tool not only in protecting the environment but also in bringing about a more efficient tax system however reforms often imply accepting sacrifices in the short run and bring about the risk of potential political opposition within this framework the debate on whether to implement green tax reforms in one step or gradually becomes of great interest in this paper we use a dynamic general equilibrium model calibrated to the spanish economy to evaluate different reforms that consist in increasing energy taxes and adjusting capital taxation in a revenue neutral framework our findings show that although an environmental dividend is always granted the existence of an efficiency dividend depends on the type of reform its size and how gradually it is implemented thus one step reforms that produce an efficiency dividend would imply large efficiency costs in the short run in this case the reform could only produce efficiency gains in the short run if it is implemented gradually although such gains would end up disappearing in the long run

inertial credit and opportunistic arrears in transition in a transition economy enterprise restructuring may exhibit a laffer curve response to tighter credit as a result of rational collective inertia in the presence of a rigid production structure unenforceable contracts and high adjustment costs a contraction in credit finance subtracts more liquidity than enterprises can generate internally because unrestructured firms are forced to extend trade credit to illiquid buyers an increase in their number increases the availability of forced supplier credit in turn increasing the attractiveness of inertial behavior as trade credit cannot be enforced a critical mass of trade and wage arrears causes pressure for a collective bailout thus validating inertial behavior even by reformable firms

structural uncertainty and subsidy removal for economies in transition abstract economies in transition are faced with a high degree of structural uncertainty i e uncertainty about which it is possible to learn through experience we study structural uncertainty s effects on a subsidy removal program subsidy removal causes unemployment but yields fiscal benefits and facilitates private sector growth when the policymaker does not know the speed with which the private sector absorbs the unemployed he will be driven toward a more decisive and therefore more informative policy the model also rationalizes policy reversals and implies that irreversibility constraints and political instability dampen the learning effect making policy more gradualist

downsizing and job insecurity this article offers an explanation of why firms downsizing patterns may vary substantially in magnitude and timing taking the form of one time massive cuts waves of layoffs or zero layoff policies the key element of this theory is that workers expectations about their job security affect their on the job performance in a situation where firms face adverse shocks the productivity effect of job insecurity forces firms to balance laying off redundant workers and maintaining survivors commitment the cost of ensuring commitment differs between firms with different characteristics and determines whether workers are laid off all at once or in stages however if firms have private information about their future profits they may not lay off any workers in order to signal a bright future boosting worker s confidence jel j21 j23 d21 d82

testing the empirical performance of stochastic volatility models of the short term interest rate i introduce two factor discrete time stochastic volatility models of the short term interest rate to compare the relative performance of existing and alternative empiricial specificattions i develop a nonlinear asymmmetric framework that allows for comparisons of non nested models featuring conditional heteoskedasticity and sensitivity of the volatility process to interest rate levels a new class of stochastic volatility models with asymmetric garch models the existing models are rejected in favor of the newly proposed models because of the asymmetric drift of the short rate and the presence of nonlinearity asymmetry garch and level effects in its volatility i test the predictive power of nested and non nested models in capturing the stochastic behavior of the risk free rate empirical evidence on three six and 12 month u s treasury bills indicates but that two factor stochastic volatility models are better than diffusion and garch models in forecasting the future level and volatility of interest rate changes

the design of reform packages under uncertainty the authors present a model of large scale economic reforms modeled on the transition process in eastern europe with aggregate and individual uncertainty concerning the outcome of reforms the government is assumed to choose the speed and sequencing of reforms the authors compare big bang strategies with gradualist reform packages they show that gradualist reform packages may be easier to get started optimal sequencing of reforms should aim at creating constituencies for further reforms and gradualism may generate a higher investment response because of a lower option value of waiting than would a big bang approach copyright 1995 by american economic association

searching for good policies policymaking is hard policymakers typically have imperfect information about which policies produce which outcomes and they are left with little choice but to fumble their way through the policy space via a trial and error process this raises a question at the heart of democracy do democratic systems identify good policies to answer this question i introduce a novel model of policymaking in complex environments i show that good policies are often but not always found and i identify the possibility of policymaking getting stuck at outcomes that are arbitrarily bad notably policy stickiness occurs in the model even in the absence of institutional constraints this raises the question of how institutions and the political environment impact experimentation and learning i show how a simple political friction uncertainty over voter preferences interacts with political competition and policy uncertainty in a subtle way that surprisingly improves the quality of policymaking over time

short rate nonlinearities and regime switches abstract using non parametric estimation methods various authors have shown distinct non linearities in the drift and volatility function of the us short rate which are inconsistent with standard affine term structure models we document how a regime switching model with state dependent transition probabilities between regimes can replicate the patterns found by the non parametric studies to do so we use data from the uk and germany in addition to us data and include term spreads in some of our models we also examine the drift and volatility function of the term spread

regime shifts in a dynamic term structure model of u s treasury bond yields this article develops and empirically implements an arbitrage free dynamic term structure model with priced factor and regime shift risks the risk factors are assumed to follow a discrete time gaussian process and regime shifts are governed by a discrete time markov process with state dependent transition probabilities this model gives closed form solutions for zero coupon bond prices an analytic representation of the likelihood function for bond yields and a natural decomposition of expected excess returns to components corresponding to regime shift and factor risks using monthly data on u s treasury zero coupon bond yields we show a critical role of priced state dependent regime shift risks in capturing the time variations in expected excess returns and document notable differences in the behaviors of the factor risk component of the expected returns across high and low volatility regimes additionally the state dependence of the regime switching probabilities is shown to capture an interesting asymmetry in the cyclical behavior of interest rates the shapes of the term structure of volatility of bond yield changes are also very different across regimes with the well known hump being largely a low volatility regime phenomenon jel g12 this article develops and empirically implements an arbitrage free dynamic term structure model dtsm with priced factor and regimeshift risks the risk factors are assumed to follow a discrete time gaussian process and regime shifts are governed by a discrete time markov process with state dependent transition probabilities agents are assumed to know both the current state of the economy and the regime they are currently in this leads to regime dependent risk neutral pricing and an equilibrium term structure that reflects the risks of both changes in the state and shifts in regimes

economic reform and dynamic political constraints in this paper we examine the impact of political constraints on economic reform plans with special reference to the transition from centrally planned to market economies we analyse the problem of an agenda setting reform minded government facing a bureaucracy or industrial sector for which allocative efficiency requires redundancies and an increase in work intensity the government also tries to minimize the rents conceded to its heterogeneous workforce we examine two types of political constraints unanimity rule and majority rule both in a one period and a two period horizon the main results are the following first of all we show how adverse selection and time consistency may generate the widely observed feature of gradualism as an ingredient of an optimal reform second under a majority rule it is shown to be possible for the government to obtain a majority vote for a reform scheme that intertemporally hurts majority interests indeed the government can improve rent extraction through the strategic use of the threat of future proposals the group which expects to be in the minority tomorrow may accept concessions while its votes can be used to extract rents from another group these results suggest that in a dynamic context democratic constraints should not be overestimated as an obstacle against efficiency enhancing economic reforms the results of this paper may throw some light on the political economy of current reforms in eastern europe governments and political decision makers in general always face political constraints when elaborating reform proposals they know that the need to overcome potential opposition from various groups of the population constrains proposals for change political constraints vary depending on the specific institutional structure of society and are clearly different under a military dictatorship than under a parliamentary democracy the role of political constraints seems particularly important in eastern europe today where new democratic governments face the huge task of achieving the transition to a market economy while the introduction of democracy may have removed some important obstacles to economic change namely the veto power of a powerful nomenclatura under communist one party rule fears are expressed that it could potentially jeopardize economic reforms which may during the transition period hurt a majority of the population what can economic theory tell us about optimal economic reform under political constraints this paper starts addressing this ambitious question by looking at structural reform focusing on a restructuring of economic sectors which requires massive redundancies and a significant rise in labour productivity our model illustrates the case of planning

speed of adjustment and self fulfilling failure of economic reform abstract an economic reform programme where inefficient public labour is laid off is considered the immediate effect is a lowering of wages and increased profitability in the private modern sector over time as capital accumulates in the modern sector wages and production increases big bang reform generates a sharp transitory drop in wages while gradual reform gives a more modest decline in the presence of a subsistence wage constraint popular resistance can cause the cancellation of big bang reform two arguments for gradualism can in that case be made first a more gradual reform requires a less abrupt drop in the wage and will therefore be feasible second the initial wage drop will be stronger if a cancellation of reform is expected and since cancellation is dependent on the severity of the initial wage drop multiple equilibria occurs the existence of multiple equilibria is dependent on the speed of reform sufficiently gradual programmes have a unique successful equilibrium

markov switching and stochastic volatility diffusion models of short term interest rates this article empirically compares the markov switching and stochastic volatility diffusion models of the short rate the evidence supports the markov switching diffusion model estimates of the elasticity of volatility parameter for single regime models unanimously indicate an explosive volatility process whereas the markov switching models estimates are reasonable itis found that either markov switching or stochastic volatility but not both is needed to adequately fit the data a robust conclusion is that volatility depends on the level of the short rate finally the markov switching model is the best for forecasting a technical contribution of this article is a presentation of quasi maximum likelihood estimation techniques for the markov switching stochastic volatility model

recent advances in estimating term structure models in the past 10 years increasingly sophisticated statistical techniques have been applied to the estimation of increasingly complex models of the term structure of interest rates in reviewing this literature we highlight the facts that have been established and the key unresolved issues the data indicate that within a wide range of interest rates mean reversion in rates is at best weak whether mean reversion is stronger for very high or very low levels of rates is an unresolved issue the absolute volatility of rates increases as the level of rates increases but the strength of this effect and the role and nature of either stochastic volatility or regime switching components in rates are still unclear unfortunately these unresolved issues have important implications for fixed income option pricing and risk measurement including value at risk calculations

the political economy of fiscal consolidations in the context of recent research in political economy this paper addresses the policy problem of fiscal consolidation in terms of three types of issues i the macroeconomic effects of alternative strategies to consolidate ii the institutional setups conducive to a consolidation and iii the best strategy for implementing a consolidation in order to maximize its political feasibility one methodological feature of this survey is an emphasis on policy feasibility one methodological feature of this survey is an emphasis on policy issues in order to bridge the gap between the level of abstraction of politico economic models of fiscal policy and the issues faced by a policymaker when attempting a fiscal consolidation

whither russia a review of andrei shleifer s a normal country in this review the author reflects on the heated debates around views about russia s postcommunist transition expressed in essays collected in new andrei shleifer s book a normal country russia after communism harvard university press 2005 which were initially published at different times during transition she focuses on the three questions that have been in the center of the debate among academics and policymakers what should the sequencing and the speed of reforms be should a country have political centralization for fiscal decentralization to be efficient is russia normal the author argues that russia s most recent history provides convincing evidence in support of the logic of political and economic transformation as it was understood by shleifer as early as the beginning of the 1990s

the term structure of interest rates and regime shifts some empirical results abstract a test of the expectations theory of the term structure in the framework of a regime switching var model for a change in the short rate and the short long spread with euro us and euro swiss franc rate data points to the importance of uncertainty about the procedures of monetary policy for the rejection of the expectations theory in the us case whereas in the swiss case a time varying term premium also seems to be relevant

implicit contracts incentive compatibility and involuntary unemployment this paper considers the enforceability of employment contracts when employees performance cannot be verified in court so that piece rate contracts are not legally enforceable part i shows that there exists a variety of self enforcing implicit contracts modelled as perfect equilibria in a repeated game and characterizes all the wage and performance outcomes that can be implemented implementation requires a strictly positive surplus from employment the form of the contract depending on how this surplus is divided between firm and employee piece rate contracts and contracts with an informally agreed bonus can be made self enforcing but the use of severance pay and bonding does not extend the set of implementable allocations the resulting contracts resemble actual labor contracts more than do the contracts in standard principal agent models part ii analyses market equilibrium with these contracts also modelled as perfect equilibria in a repeated game and shows that many such equilibria exist unfilled vacancies and unemployed workers can co exist despite the existence of contracts that are potentially mutually beneficial for those jobs that are filled any division of the potential surplus is possible so that the market can have at the same time involuntary unemployment and vacancies that are unfilled despite filled jobs earning positive profits as a criterion for selecting equilibria a notion of renegotiation proofness is applied then either all workers are employed or all jobs filled but any division of the potential surplus is still possible the paper explores what further restrictions on beliefs give rise to a walrasian outcome in which all the potential surplus goes to the short side of the market and to an efficiency wage type outcome in which the potential surplus goes to the long side

factors of the term structure of sovereign yield spreads abstract we investigate the term structure of sovereign yield spreads for five advanced economies against the us and provide novel insights on the key drivers of the term structure we show that the spread term structure dynamics are driven by three latent factors which can be labeled as spread level slope and curvature similar to common interpretations found in the yield curve literature we further show that these estimated spread factors have predictive power for exchange rate movements and excess returns above the predictability of an uncovered interest rate parity approach as the yield curve contains information about expected future economic conditions we conjecture that these yield spread factors reflect expected macroeconomic differentials which in turn drive exchange rates using the information content of yield spread curves may thus be a promising approach to improve the forecasting accuracy of exchange rate models

radicalism versus gradualism an analytical survey of the transition strategy debate academic debate on a transition strategy for former socialist economies continues even a quarter century after the collapse of the communism in central and eastern europe and the former soviet union in this paper through an analytical survey of 137 preceding studies we present an overall picture of the debate and examine the relationship between the debate attitudes and the literature attributes in related studies we found that the radicalists maintain a consistent debate attitude from the viewpoints of time speed and policy sequence of economic transition while the debate attitude of the gradualists is more diversified we also found that there is another group of researchers that stays within the framework of the radicalism versus gradualism debate while at the same time keeping at arm s length from both the radicalists and the gradualists in addition our regression estimation of qualitative selection models provides interesting findings on the relationship between the debate attitudes and the literature attributes

why is china different from eastern europe perspectives from organization theory we draw from recent work in organization theory to explain the differences in reform strategies between china and eastern europe an experimentation approach was adopted in china whereas a big bang approach was more favored in eastern europe the explanation is based on differences in the organizational structure of central planning u form in eastern europe and m form in china the m form is more flexible because it makes local experiments possible contrary to the u form where this would give rise to major complications in coordination

multivariate term structure models with level and heteroskedasticity effects abstract the paper introduces and estimates a multivariate level garch model for the long rate and the term structure spread where the conditional volatility is proportional to the th power of the variable itself level effects and the conditional covariance matrix evolves according to a multivariate garch process heteroskedasticity effects the long rate variance exhibits heteroskedasticity effects and level effects in accordance with the square root model the spread variance exhibits heteroskedasticity effects but no level effects the level garch model is preferred above the garch model and the level model garch effects are more important than level effects the results are robust to the maturity of the interest rates

democracy market liberalization and political preferences abstract we estimate the impact of market development and democratization on subjective political preferences we rely on the specific situation of frontier zones and the considerable regional variations in culture and economic development in the countries of the former socialist bloc for identification using a survey conducted in 2006 we find a positive and significant effect of democracy on support for a market economy but no effect of market liberalization on support for democracy hence in contrast with the conventional wisdom concerning the sequencing of political and economic reforms democratization may become a necessary condition to obtain public support for further economic liberalization

the existence of self enforcing implicit contracts implicit contracts are nontrivial nash equilibria to the post hiring trading game between a worker and the employer these are supported by intrafirm rather than labor market reputations the existence of an implicit contract that supports efficient trade is proved in a simple model

relational incentive contracts standard incentive theory models provide a rich framework for studying informational problems but assume that contracts can be perfectly enforced this paper studies the design of self enforced relational contracts i show that optimal contracts often can take a simple stationary form but that self enforcement restricts promised compensation and affects incentive provision with hidden information it may be optimal for an agent to supply the same inefficient effort regardless of cost conditions with moral hazard optimal contracts involve just two levels of compensation this is true even if performance measures are subjective in which case optimal contracts terminate following poor performance jel c73 d82 l14

divide et impera strategic underpricing in privatizations in several recent initial public offerings in privatization casesshares seemed to be severely underpriced in this paper weprovide a political economy explanation for this apparentunderpricing using a variant of grossmann and helpmann s 1996 model of special interest politics we demonstrate thatgovernments may raise their election chances by rationinginvestors because the resulting broader distribution of sharesmakes regulation that is favorable to the privatized firm morepopular somewhat surprisingly even revenues from theprivatization can be increased through rationing the model alsoexplains the common practice of bonus systems designed to preventinvestors from taking profits immediately

the virtues of gradualism and legitimacy in the transition to a market economy this paper presents a simplified model of sectoral restructuring in eastern europe a move towards allocative efficiency is desired by the reform minded government but the shift to higher productivity which such efficiency requires would lead to massive layoffs and labour reallocation in the transition period we look at the impact of political constraints unanimity and or majority worker approval on reform proposals when the government faces a heterogeneous workforce holding private information on relative outside opportunities when the budgetary consequences of exit compensations are so important as to make partial reforms preferable to full reforms gradualism emerges as the optimum in a dynamic context without government commitment it is also shown that under democratic majority rule a government in control of the agenda of reforms can win majority approval for plans which end up hurting majority interests intertemporally by threatening to switch majorities in future reform proposals this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item

time varying volatility and the dynamic behavior of the term structure in this paper the authors consider a framework in which the cross sectional and time series behavior of the yield curve can be studied simultaneously they examine the relationship between the yield curve and the time varying conditional volatility of the treasury bill market the authors demonstrate that different shaped yield curves can result given different combinations of volatility and expectations about future spot rates moreover adjusting the forward rate for the volatility related forward premium can improve its performance as a predictor for the future spot rate copyright 1993 by ohio state university press

the political economy of transition the overriding importance of political constraints in the transition process has led to developments of the theory of the political economy of reform what are the main insights from that theory how does it reflect the transition reality what have we learned and what do we still need to learn the present article will attempt to answer those questions

economic reform voting and local political intervention evidence from india abstract this paper uses the indian tariff reforms of the early nineties to estimate how voters hurt by economic reforms respond regions more hurt by the tariff reform increased their support for both the party that initiated their suffering and parties with similar preferences in favor of poverty centric policies this response is surprisingly sophisticated where voters did not simply punish incumbents for negative income shocks and correctly discounted initial anti reform stances by opposition parties that later turned out to be false furthermore the strength of this voting response varied with both geography and local political incentives suggesting that the economic effects of reforms might vary substantially in large and decentralized democracies

long run trends in workers beliefs about their own job security evidence from the general social survey in recent years federal reserve chairman alan greenspan former u s secretary of labor robert reich and many journalists have argued that workers are more anxious about losing their jobs than they were in the past i use the 1977 96 general social survey to document trends in workers beliefs about their own job security during the 1990s workers have been more pessimistic about losing their jobs in the next 12 months than workers were during the 1980s workers have also been more concerned about suffering future job loss that would have resulted in a decline in earnings or a spell of unemployment

do production subsidies have a wage incidence in wind power employment in electricity generation from renewable resources has expanded rapidly in the us and in texas during the last decade availability of the production tax credit ptc has been an important driver of this growth using establishment level employment and payroll data for texas at the north american industrial classification system naics 6 level we analyse the differences in average wages between firms generating electricity from fossil fuels and those generating electricity from wind power we compare relative average wages before and after the rapid expansion of wind power development that followed the ex ante renewal of the ptc in 2006 our main finding using both the parametric and nonparametric estimation techniques proposed by racine and li 2004 is that average payrolls for wind power generators increased relative to fossil fuel based electricity generators after 2006

when order affects performance culture behavioral spillovers and institutional path dependence evidence suggests that the cultural context influences the performance of laws policies and political institutions descriptive accounts reveal that outcomes and behaviors often depend on the array of historical institutions this article presents a multi institutional framework that can account for those findings through path dependent behavioral spillovers individuals learn equilibrium behaviors when interacting in a new institutional setting initially some individuals choose behaviors that align with their behaviors in similar extant institutions creating a cultural context that can lead to inefficient outcomes the article shows how avoiding path dependence requires sequencing or designing institutions to maintain behavioral diversity optimal sequencing thus requires positioning institutions with clear incentives early in the sequence as well as avoiding strong punishments that can stifle attempts to break established behavioral patterns

reforms lobbies and welfare a common agency approach citizens with heterogeneous tastes delegate to policy makers the authority to choose public policies they may try to influence legislators in various ways in this paper we assume that monetary lobbying and direct threats are the only instruments private individuals can use to influence the legislator we model the relationship between the citizens and a single policy maker as a common agency game lobbies offer a policy and a payment according to a truthful contribution schedule and the government takes the policy decision in the truthful equilibrium the government implements the social surplus maximizing policy introducing also direct threats we find that as far as both groups have an instrument to influence the legislator the efficiency result is robust we also show that when the lobby groups have asymmetric interests and political power not all groups necessarily participate in the auction in particular it turns out that one lobby or non lobby equilibria may arise and those equilibria are also efficient

wind power development in the united states abstract this paper analyzes the drivers of wind power development in the united states focusing on government renewable energy incentives and access to the electricity grid the effects of wind capacity electricity transmission line coverage and grid regulation as well as state and federal subsidies from 1998 to 2007 are estimated via random effects tobit probit and ordinary least squares instrumental variables regression the results indicate that the federal production tax credit state level sales tax credit and production incentives play an important role in promoting wind power in addition higher wind power penetration levels can be achieved by bringing more parts of the electricity transmission grid under independent system operator regulation this paper concludes that state and federal government policies play a significant role in wind power development both by providing financial support and by improving physical and procedural access to the electricity grid

learning dynamics and support for economic reforms why good news can be bad support for economic reforms has often shown puzzling dynamics many reforms that began successfully lost public support this paper shows that learning dynamics can rationalize this paradox because the process of revealing reform outcomes is an example of sampling without replacement this concept challenges the conventional wisdom that one should begin by revealing reform winners it may also lead to situations in which reforms that enjoy both ex ante and ex post majority support will still not come to completion the framework can be used to explain why gradual reforms worked well in china where successes in special economic zones facilitated further reform whereas this was much less the case for latin american and central and eastern european countries

yield factor volatility models the term structure of interest rates is often summarized using a handful of yield factors that capture shifts in the shape of the yield curve in this paper we develop a comprehensive model for volatility dynamics in the level slope and curvature of the yield curve that simultaneously includes level and garch effects along with regime shifts we show that the level of the short rate is useful in modeling the volatility of the three yield factors and that there are significant garch effects present even after including a level effect further we find that allowing for regime shifts in the factor volatilities dramatically improves the model s fit and strengthens the level effect we also show that a regime switching model with level and garch effects provides the best out of sample forecasting performance of yield volatility we argue that the auxiliary models often used to estimate term structure models with simulation based estimation techniques should be consistent with the main features of the yield curve that are identified by our model

impact of public policy uncertainty on renewable energy investment wind power and the production tax credit abstract it is generally understood that the pattern of repeated expiration and short term renewal of the federal production tax credit ptc causes a boom bust cycle in wind power plant investment in the us this on off pattern is detrimental to the wind industry since ramp up and ramp down costs are high and players are deterred from making long term investments it is often assumed that the severe downturn in investment during off years implies that wind power is unviable without the ptc this assumption turns out to be unsubstantiated this paper demonstrates that it is not the absence of the ptc that causes the investment downturn during off years but rather the uncertainty over its return specifically it is the dynamic of power purchase agreement ppa negotiations in the face of ptc renewal uncertainty that drives investment volatility with contract negotiations prevalent in the renewable energy industry this finding suggests that reducing uncertainty is a crucial component of effective renewable energy policy the ptc as currently structured is not the only means existing or potential for encouraging wind power investment using data from a survey of energy professionals various policy instruments are compared in terms of their perceived stability for supporting long term investment

the efficient mechanism for downsizing the public sector this article analyzes the efficient mechanism for downsizing the public sector focusing on adverse selection in productive efficiency each worker is assumed to have two type dependent reservation utilities the status quo utility in the public sector before downsizing and the utility that the worker expects to obtain by entering the private sector the efficient mechanism consists of a menu of probability of remaining in the public sector and transfer pairs that induces self selection a worker s full cost is defined by the sum of production cost in the public sector and reservation utility in the private sector it is optimal to start by laying off the agents with higher full cost when the public sector before downsizing is discriminating as the differential of private information about productive efficiency suggests there are countervailing incentives this makes the size of downsizing smaller under asymmetric information than under complete information

capital accumulation unemployment and self fulfilling failure of economic reform abstract i consider fiscal reform and the consequences of expectations about reform cancellation the reform implies reduced taxes and the laying off of employees in an inefficient public sector if the resulting unemployment level declines sufficiently fast the reform is completed on the other hand if high unemployment levels prevail for too long the reform is cancelled cancellation affects the return on capital negatively hence expectations about cancellation will depress capital accumulation and increase the level of unemployment as a result multiple rational expectation equilibria may arise where expectations about cancellation prove self fulfilling the modelling framework is leontief technology in combination with ramsey optimization that exhibits simple and attractive algebra

idiosyncratic variation of treasury bill yields i document a dramatic increase in the importance of two types of variation in treasury bill yields beginning in the early 1980s the first is idiosyncratic variation in individual short maturity less than three months bill yields the second is a common component in treasury bill yields that is not shared by yields on other instruments such as short maturity privately issued instruments or longer maturity treasury notes and bonds some evidence suggests the first type reflects increased market segmentation these results have important implications for the calibration and testing of no arbitrage term structure models and interpreting tests of the expectations hypothesis united states treasury bill yields play a central role in economists efforts to understand the behavior of financial markets the focus on treasury bills is driven by the belief that bill yields can be viewed as benchmarks from which yields on other debt instruments are derived for example in no arbitrage models of the default free term structure the stochastic properties of the hypothetical instantaneous interest rate determine bond prices researchers often construct and evaluate these models using short maturity bill yields as proxies for instantaneous interest rates similarly bill yields are frequently used to test the expectations hypothesis of the term structure 2 economists standard pricing models for default risky securities also view treasury yields as building blocks in such models yields on default risky securities depend at least in part on the yields of default free securities and the underlying stochastic default process therefore yields on treasury bills have been used in studies of the effects of monetary policy on the business cycle not because bills are intrinsically critical to the economy but because

heterogeneous effects of competitiveness shocks on macroeconomic performance across euro area countries this paper considers how competitiveness impacts macroeconomic performance in 11 euro area countries var models are estimated for the individual countries using quarterly data from 1995q4 to 2013q4 besides unit labour costs as a competitiveness measure the models include gdp the current account balance and domestic credit the empirical analyses show that changes in unit labour costs help explain gdp dynamics in the short and medium term in most countries whereas they have little explanatory power for the current account balance or domestic credit for most countries overall the effects of the unit labour costs vary substantially across the countries in the euro area the heterogeneity suggests that policy measures aiming to improve economic growth correct current account imbalances and ensure financial stability need to take country specific features into account

financial liberalization and reversals political and economic determinants what accounts for the dynamics of financial reforms this paper identifies the political regime as one of the main factors focusing on democratization and financial reform it puts forward novel evidence for a u shaped relation across countries and over time for different reform measures and a wide range of estimators partial democracy is a main obstacle to financial reforms and democratization when incomplete may lead to severe financial reform reversals nauro f campos and fabrizio coricelli

holding on for too long an experimental study on inertia in entrepreneurs and non entrepreneurs disinvestment choices abstract disinvestment in the sense of project termination and liquidation of assets including the cession of a venture is an important realm of entrepreneurial decision making this study presents the results of an experimental investigation modeling the choice to disinvest as a dynamic problem of optimal stopping in which the patterns of decisions are analyzed with entrepreneurs and non entrepreneurs our experimental results reject the standard net present value approach as an account of observed behavior instead most individuals seem to understand the value of waiting their choices are weakly related to the disinvestment triggers derived from a formal optimal stopping benchmark consistent with real options reasoning we also observe a pronounced psychological inertia i e most individuals hold on to a losing project for even longer than real options reasoning would predict the study provides evidence for entrepreneurs and non entrepreneurs being quite similar in their behavior

subjective performance measures in optimal incentive contracts objective measures of performance are seldom perfect in response incentive contracts often include important subjective components that mitigate incentive distortions caused by imperfect objective measures this paper explores the combined use of subjective and objective performance measures in respectively implicit and explicit incentive contracts naturally objective and subjective measures often are substitutes sometimes strikingly so we show that if objective measures are sufficiently close to perfect then no implicit contracts are feasible because the firm s fallback position after reneging on an implicit contract is too attractive we also show however that objective and subjective measures can reinforce each other if objective measures become more accurate then in some circumstances the optimal contract puts more weight on subjective measures because the improved objective measures increase the value of the ongoing relationship and so reduce the firm s incentive to renege we also analyze the use of subjective weights on objective performance measures and provide case study evidence consistent with our analyses

after the honeymoon on the economics and the politics of economic transformation this paper focuses on the obvious pareto improving programmes may fail to improve everyone s lot politically it has often been interpreted as a requirement that a majority should benefit from the change events in central and eastern europe suggest otherwise and cast doubt on the relevance of the median voter theorem the addition of minority discontents may result in major political difficulties that lead governments to avoid actions that generate strong minority objections as a result the technically best crafted plans may be rejected for political reasons in addition reform programmes which are ex ante politically acceptable may well become rejected ex post after they are implemented one solution is to introduce a heavy dose of egalitarian income distribution even if it runs against labour supply incentives this abstract was borrowed from another version of this item

after the big bang obstacles to the emergence of the rule of law in post communist societies when russia launched mass privatization it was widely believed that it would create a powerful constituency for the rule of law that didn t happen we present a dynamic equilibrium model of the political demand for the rule of law and show that beneficiaries of mass privatization may fail to demand the rule of law even if it is the pareto efficient rule of the game the reason is that uncertainty about the legal regime can lead to asset stripping and stripping can give agents an interest in prolonging the absence of the rule of law this abstract was borrowed from another version of this item

selective intervention and internal hybrids interpreting and learning from the rise and decline of the oticon spaghetti organization infusing hierarchies with elements of market control has become a much used way of simultaneously increasing entrepreneurialism and motivation in firms however this paper argues that such internal hybrids particularly in their radical forms are inherently hard to successfully design and implement because of a fundamental incentive problem of establishing credible managerial commitments to not intervene in delegated decision making this theme is developed and illustrated using the case of the world leading hearing aids producer oticon in the beginning of the 1990s oticon became famous for its radical internal hybrid the spaghetti organization recent work has interpreted the spaghetti organization as a radical attempt to foster dynamic capabilities by organizational means neglecting however that about a decade later the spaghetti organization has given way to a more traditional matrix organization in contrast an organizational economics interpretation of oticon organizational changes is developed this lens suggests that a strong liability of the spaghetti organization was the above incentive problem frequent managerial meddling with delegated rights led to a severe loss of motivation and arguably caused the change to a more structured organization refutable implications are developed and the discussion is broadened to more general issues of economic organization

exiting a lawless state an earlier paper showed that an economy could be trapped in an equilibrium state in which the absence of the rule of law led to asset stripping and the prevalence of asset stripping led to the absence of a demand for the rule of law highlighting a coordination failure this paper looks more carefully at the dynamics of transition from a non rule of law state the paper identifies a commitment problem as the critical feature inhibiting the transition the inability under a rule of law to forgive theft this can lead to the perpetuation of the non rule of law state even when it might seem that the alternative is pareto improving

do bonds span the fixed income markets theory and evidence for unspanned stochastic volatility most term structure models assume bond markets are complete that is that all fixed income derivatives can be perfectly replicated using solely bonds however we find that in practice swap rates have limited explanatory power for returns on at the money straddles portfolios mainly exposed to volatility risk we term this empirical feature unspanned stochastic volatility usv while usv can be captured within an hjm framework we demonstrate that bivariate models cannot exhibit usv we determine necessary and sufficient conditions for trivariate markov affine systems to exhibit usv for such usv models bonds alone may not be sufficient to identify all parameters rather derivatives are needed

discretionary policy implementation and reform abstract regulatory agencies treaty negotiators and other delegates often possess considerable authority over the details of policy change i examine how such discretion can block a pareto improving reform when policy change requires the support of both the liberal and conservative factions gridlock reform and reform paradoxes all emerge as cases in a general model with perfect information a reformer with unknown policy preferences can facilitate escape from a gridlock equilibrium

rational expectations econometric analysis of changes in regime an investigation of the term structure of interest rates abstract this paper is of interest both for its methodological contribution of new tools for analyzing rational expectations models and for its substantive conclusions concerning the term structure of interest rates during the monetary experiment of october 1979 the paper studies systems subject to changes in regime interpreted here as occasional discrete shifts in the parameters governing the time series behavior of exogenous economic variables the specification is shown to be quite tractable both theoretically and empirically the technique is used to analyze yields on three month treasury bills and ten year treasury bonds during 1962 to 1987 a constant parameter linear model for short term rates is shown to be inconsistent both with the univariate time series properties of short rates and with the observed bivariate relation between long and short rates under the expectations hypothesis of the term structure an alternative nonlinear model that admits the possibility of changes in regime affords a much better description of the univariate process for short rates moreover the cross equation restrictions implied by the expectations hypothesis of the term structure are consistent with the nonlinear specification indeed the residuals of the restricted relation have a standard error of only 0 8 basis points this is a third less than that of a completely unrestricted linear regression of long rates on short rates and compares with an unconditional standard deviation of long rates of 142 basis points i conclude that once the recognition by bond traders of changes in regime is taken into account the expectations hypothesis of the term structure of interest rates holds up fairly well for these data

priorities and sequencing in privatization evidence from czech firm panel data abstract while privatization of state owned enterprises has been one of the most important aspects of the economic transition from a centrally planned to a market system no transition economy has privatized all its firms simultaneously this raises the question of whether governments privatize firms strategically in this paper we examine the determinants of the sequencing of privatization to obtain testable predictions about the factors that may affect sequencing we investigate the following competing government objectives i maximizing efficiency through resource allocation ii maximizing public goodwill from the free transfers of shares to the public iii minimizing political costs iv maximizing efficiency through information gains and v maximizing privatization revenues next we use firm level data from the czech republic to test the competing predictions about the sequencing of privatization consistent with the hypotheses of a government priority on revenues and public goodwill we find strong evidence that more profitable firms were privatized first the sequencing of privatization is also consistent with maximizing efficiency through information gains our results indicate that many empirical studies of the effects of privatization on firm performance suffer from a selection bias

price and advertising signals of product quality we present a signaling model based on ideas of phillip nelson in which both the introductory price and the level of directly uninformative advertising or other dissipative marketing expenditures are choice variables and may be used as signals for the initially unobservable quality of a newly introduced experience good repeat purchases play a crucial role in our model a second focus of the paper is on illustrating an approach to refining the set of equilibria in signalling games with multiple potential signals

trade capital and the transition in central europe the potential for export oriented growth and the impact of official capital injections is assessed for five central european countries in the years 1990 2000 by means of a neoclassical simulation model export growth is essential for the transition to a market oriented economy and the recovery of central europe implying the need for trade liberalization by both the east and the west if this condition is being met satisfactory gdp growth rates appear possible even without external financial support

reforms and confidence abstract we examine the choice of economic reforms when policymakers have present biased preferences and can choose to discard information maintain confidence to mitigate distortions from excess discounting the decisions of policymakers and firms are shown to be interdependent confident policymakers carry out welfare improving reforms more often which increases the probability that firms will invest in restructuring while policymakers in different countries can be equally irrational the consequences of bounded rationality are less severe in economies with beneficial initial conditions we also examine how present biased preferences influence the choice between big bang versus gradualist reform strategies our findings help explain differences in economic reform success in various countries
