the economic determinants of interest rate option smiles we address three questions relating to the interest rate options market what is the shape of the smile what are the economic determinants of the shape of the smile do these determinants have predictive power for the future shape of the smile and vice versa we investigate these issues using daily bid and ask prices of euro interest rate caps floors we find a clear smile pattern in interest rate options the shape of the smile varies over time and is affected in a dynamic manner by yield curve variables and the future uncertainty in the interest rate markets it also has information about future aggregate default risk our findings are useful for the pricing hedging and risk management of these derivatives

the relative valuation of caps and swaptions theory and empirical evidence although traded as distinct products caps and swaptions are linked by noarbitrage relations through the correlation structure of interest rates using a string market model we solve for the correlation matrix implied by swaptions and examine the relative valuation of caps and swaptions we find that swaption prices are generated by four factors and that implied correlations are lower than historical correlations long dated swaptions appear mispriced and there were major pricing distortions during the 1998 hedge fund crisis cap prices periodically deviate significantly from the no arbitrage values implied by the swaptions market the growth in interest rate swaps during the past decade has led to the creation and rapid expansion of markets for two important types of swap related derivatives interest rate caps and swaptions these over the counter derivatives are widely used by many firms to manage their interest rate risk exposure and collectively represent the largest class of fixed income options in the financial markets the international swaps and derivatives association isda estimates that the total notional amount of caps and swaptions outstanding at the end of 1997 was over 4 9 trillion which was more than 300 times the 15 billion notional of all chicago board of trade treasury note and bond futures options combined caps and swaptions are generally traded as separate products in the financial markets and the models used to value caps are typically different from those used to value swaptions furthermore most wall street firms use a piecemeal approach in calibrating their models for caps and swaptions making it difficult to evaluate whether these derivatives are fairly priced

interest rate caps smile too but can the libor market models capture the smile using 3 years of interest rate caps price data we provide a comprehensive documentation of volatility smiles in the caps market to capture the volatility smiles we develop a multifactor term structure model with stochastic volatility and jumps that yields a closed form formula for cap prices we show that although a three factor stochastic volatility model can price at the money caps well significant negative jumps in interest rates are needed to capture the smile the volatility smile contains information

out of step out of office electoral accountability and house members voting does a typical house member need to worry about the electoral ramifications of his roll call decisions we investigate the relationship between incumbents electoral performance and roll call support for their party controlling for district ideology challenger quality and campaign spending among other factors through a series of tests of the 1956 1996 elections the tests produce three key findings indicating that members are indeed accountable for their legislative voting first in each election an incumbent receives a lower vote share the more he supports his party second this effect is comparable in size to that of other widely recognized electoral determinants third a member s probability of retaining office decreases as he offers increased support for his party and this relationship holds for not only marginal but also safe members

interest rate swaps abstract using quotations from two interest rate swap dealers with different credit ratings aaa and a we examine the effect of dealers credit reputations on swap quotations and bid offer spreads the aaa offer rates are significantly higher than the a offer rates and the aaa bid rates are significantly lower than the a bid rates we also document the relation between swap rates and par bond yields estimated from london interbank offered rate libor and bid rate libid data we identify some of the problems in testing the implications of swap pricing theory

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

a joint framework for consistently pricing interest rates and interest rate derivatives dynamic term structure models explain the yield curve variation well but perform poorly in pricing and hedging interest rate options most existing option pricing practices take the yield curve as given thus having little to say about the fair valuation of the underlying interest rates this paper proposes an m n model structure that bridges the gap in the literature by successfully pricing both interest rates and interest rate options the first m factors capture the yield curve variation whereas the latter n factors capture the interest rate options movements that cannot be effectively identified from the yield curve we propose a sequential estimation procedure that identifies the m yield curve factors from the libor and swap rates in the first step and the n options factors from interest rate caps in the second step the three yield curve factors explain over 99 of the variation in the yield curve but account for less than 50 of the implied volatility variation for the caps incorporating three additional options factors improves the explained variation in implied volatilities to over 99

the valuation of floating rate instruments abstract a framework for valuing floating rate notes is developed to examine the effects of 1 lags in the coupon formula 2 special contractual features and 3 default risk evidence from a sample of floaters indicates they sold at significant discounts while lags in the coupon formulas and other contractual features make these notes more variable they do not account for the magnitude of the discounts we conclude that the fixed default premium in the coupon formula of a typical note is inadequate to compensate for time varying default premiums demanded by investors who treat other corporate short term paper as close substitutes

bond pricing and the term structure of interest rates a new methodology for contingent claims valuation this paper presents a unifying theory for valuing contingent claims under a stochastic term structure of interest rates the methodology based on the equivalent martingale measure technique takes as given an initial forward rate curve and a family of potential stochastic processee for its subsequent movements a no arbitrage condition restricts this family of processes yielding valuation formulae for interest rate sensitive contingent claims which do not explicitly depend on the market prices of risk examples are provided to illustrate the key results in relation to the term structure of interest rates arbitrage pricing theory has two purposes the first is to price all zero coupon default free bonds of varying maturities from a finite number of economic fundamentals called state variables the second is to price all interest rate sensitive contingent claims taking as given the prices of the zero coupon bonds this paper presents a general theory and a unifying framework for understanding arbitrage pricing theory in this context of which all existing arbitrage pricing models are special cases in particular vasicek 1977 brennan and schwartz 1979 langetieg 1980 ball and torous 1983 ho and lee 1986 schaefer and schwartz 1987 and artzner and delbaen 1988 the primary contribution of this paper however is a new methodology for solving the second problem i e the pricing of interest rate sensitive contingent claims given the prices of all zero coupon bonds the methodology is new because i it imposes its stochastic structure directly on the evolution of the forward rate curve ii it does not require an inversion of the term structure to eliminate the market prices of risk from contingent claim values and iii it has a stochastic spot rate process with multiple stochastic factors influencing the term structure the model can be used to consistently price and hedge all contingent claims american or european on the term structure and it is derived from necessary and more importantly sufficient conditions for the absence of arbitrage the arbitrage pricing models of vasicek 1977 brennan and schwartz 1979 langetieg 1980 and artzner and delbaen 1988 all require an iformerly titled bond pricing and the term structure of interest rates a new methodology

the effect of the expansion of the voting franchise on the size of government this paper examines the claim that expansion of the voting franchise has been an important factor in the growth of government state government spending and state and local spending are explained using a panel of 46 states for 1950 88 elimination of poll taxes and literacy tests led to higher turnout particularly among the poor and a poorer pivotal voter as predicted we find that these changes a fall in the income of voters relative to state income and the ouster of republicans from state government led to a sharp rise in welfare spending but no change in other spending

identifying volatility risk premia from fixed income asian options abstract fixed income options are frequently adopted by companies to hedge interest rate risk their payoff dependence on the cumulative short term rate makes them particularly informative about interest rate volatility risk based on a joint dataset of bonds and asian interest rate options we study the interrelations between bond and volatility risk premia in a major emerging fixed income market we propose a dynamic term structure model that generates an incomplete market compatible with a preliminary empirical analysis of the dataset approximation formulas for at the money asian option prices avoid the use of computationally intensive fourier transform methods allowing for an efficient implementation of the model the model generates a bond risk premium strongly correlated with a widely accepted emerging market benchmark index embi global and a negative volatility risk premium consistent with the use of asian options as insurance in this market

an economic analysis of interest rate swaps interest rate swaps a financial innovation in recent years are based upon the principle of comparative advantage an interest rate swap is a useful tool for active liability management and for hedging against interest rate risk the purpose of this paper is to provide a simple economic analysis of interest rate swaps alternative uses of and the appropriate valuation procedure for interest rate swaps are described the significant increase in both the levels and the volatilities of market interest rates since the late 70 s has resulted in substantially higher interest rate risks faced by business firms and financial institutions the problem and consequences of interest rate risk exposure are particularly serious for firms in which the duration of assets does not match the duration of the liabilities for instance most financial institutions and many corporations financed long term fixed rate assets with short term floating rate liabilities such firms lose when the shortterm interest rates in the market rise unexpectedly because for given fixed rates of return on their assets the short term interest costs that they have to pay rise with the market interest rates conversely these firms gain from an unexpected decline in short term market interest rates in recent years the introduction and the development of new financial products in the capital markets such as interest rate futures interest rate options and interest rate swaps represent logical responses to the increased need to reduce firms exposure to interest rate risk

the public as thermostat dynamics of preferences for spending theory democratic accountability requires that the public be reasonably well informed about what policymakers actually do such a public would adjust its preferences for more or less policy in response to policy outputs themselves in effect the public would behave like a thermostat when the actual policy temperature differs from the preferred policy temperature the public would send a signal to adjust policy accordingly and once sufficiently adjusted the signal would stop hypotheses in domains where policy is clearly defined and salient to the public changes in the public s preferences for more policy activity are negatively related to changes in policy methods a thermostatic model of american public preferences for spending on defense and a set of five social programs is developed and then tested using time series regression analysis results changes in public preferences for more spending reflect changes in both the preferred levels of spending and spending decisions themselves most importantly changes in preferences are negatively related to spending decisions whereby the public adjusts its preferences for more spending downward upward when appropriations increase decrease thus consistent with the eastonian model policy outputs do feed back on public inputs at least in the defense spending domain and across a set of social spending domains

the tips treasury bond puzzle we show that the price of a treasury bond and an inflation swapped treasury inflation protected securities tips issue exactly replicating the cash flows of the treasury bond can differ by more than 20 per 100 notional treasury bonds are almost always overvalued relative to tips total tips treasury mispricing has exceeded 56 billion representing nearly 8 of the total amount of tips outstanding we find direct evidence that the mispricing narrows as additional capital flows into the markets this provides strong support for the slow moving capital explanation of arbitrage persistence

unspanned stochastic volatility and fixed income derivatives pricing we propose a parsimonious unspanned stochastic volatility model of the term structure and study its implications for fixed income option prices the drift and quadratic variation of the short rate are affine in three state variables the short rate its long term mean and variance which follow a joint markov vector process yet bond prices are exponential affine functions of only two state variables independent of the current interest rate volatility level because this result holds for an arbitrary volatility process such a process can be calibrated to match fixed income derivative prices furthermore this model can be extended by relaxing the time homogeneity to fit any arbitrary term structure in its hjm form this model nests the analogous stochastic equity volatility model of heston 190 heston s l 1993 a closed form solution for options with stochastic volatility review of financial studies 6 327 343 in particular if the volatility process is specified to be affine closed form solutions for interest rate options obtain we propose an efficient algorithm to compute these prices an application using data on caps and floors shows that the model can capture very well the implied black spot volatility surface while simultaneously fitting the observed term structure c 2005 elsevier b v all rights reserved

the statistical analysis of roll call data modern studies of legislative behavior focus upon the relationship among the policy preferences of legislators institutional arrangements and legislative outcomes in spatial models of legislatures policies are represented geometrically as points in a low dimensional euclidean space each legislator has a most preferred policy or ideal point in this space and his or her utility for a policy declines with the distance of the policy from his or her ideal point see davis hinich and ordeshook 1970 for an early survey the primary use of roll call data the recorded votes of deliberative bodies 1 is the estimation of ideal points the appeal and importance of ideal point estimation arises in two ways first ideal point estimates let us describe legislators and legislatures the distribution of ideal points estimates reveals how cleavages between legislators reflect partisan affiliation or region or become more polarized over time e g mccarty poole and rosenthal 2001 roll call data serve similar purposes for interest groups such as americans for democratic action the national taxpayers union and the sierra club to produce ratings of legislators along different policy dimensions second estimates from roll call analysis can be used to test theories of legislative behavior for instance roll call analysis has been used in studies of the u s congress both contemporary and

the dynamics of the forward interest rate curve a formulation with state variables the objective of this paper is twofold first the paper develops a class of models of the term structure of interest rates in the heath jarrow and morton 1992 framework with dynamics characterized by the evolution of a small set of state variables second the paper exploits this characterization of the dynamics of the term structure in an estimation exercise that makes use of both the time series and cross section of bond prices in this way our class of models bridges the gap between traditional models such as cox ingersoll and ross 1985 and vasicek 1977 that emphasize the dynamics of interest rates and the models of heath jarrow and morton 1992 that stress fitting the cross section of bond prices

pricing and hedging interest rate options evidence from cap floor markets we examine the pricing and hedging performance of interest rate option pricing models using dailydata on us dollar cap and floor prices across both strike rates and maturities our results show that fitting the skew of the underlying interest rate probability distribution provides accurate pricing results within a one factor framework however for hedging performance introducing a second stochastic factor is more important than fitting the skew of the underlying distribution this constitutes evidence against claims in the literature that correctly specified and calibrated one factor models could replace multi factor models for consistent pricing and hedging of interest rate contingent claims 2004 elsevier b v all rights reserved

a model of the political economy of the united states we develop and test a model of joint determination of economic growth and national election results in the united states the formal model which combines developments in the rational choice analysis of the behavior of economic agents and voters leads to a system of equations in which the dependent variables are the growth rate and the vote shares in presidential and congressional elections our estimates support the theoretical claims that growth responds to unanticipated policy shifts and that voters use both on year and midterm elections to balance the two parties on the other hand we find no support for rational retrospective voting we do reconfirm in a fully simultaneous framework the naive retrospective voting literature s finding that the economy has a strong effect on presidential voting we find congressional elections unaffected by the economy except as transmitted by presidential coattails

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

throwing away a billion dollars the cost of suboptimal exercise strategies in the swaptions market abstract this paper studies the costs of applying single factor exercise strategies to american swap options when the term structure is actually driven by multiple factors using a multifactor string market model of the term structure we find that even when single factor models are recalibrated to match the market at every exercise date the exercise strategies they imply can be suboptimal based on estimates of notional amounts outstanding the total present value costs of following single factor strategies could be several billion dollars these results illustrate the importance of using well specified term structure models

an empirical examination of the convexity bias in the pricing of interest rate swaps abstract this paper examines the convexity bias caused by the non linearity of payoffs in the pricing of interest rate swaps off the eurocurrency futures curve the evidence from four major currencies dm and during 1987 1996 suggests that swaps were initially being priced off the futures curve ignoring the convexity adjustment subsequently the market swap rates drifted below the rates implied by futures prices after rejecting alternative explanations we use alternative term structure models to show that the convexity bias is related to the empirically observed swap futures differential we interpret these results as evidence of mispricing of swap contracts during the early years which was eliminated over time

hedging in the possible presence of unspanned stochastic volatility evidence from swaption markets this paper examines whether higher order multifactor models with state variables linked solely to underlying libor swap rates are by themselves capable of explaining and hedging interest rate derivatives or whether models explicitly exhibiting features such as unspanned stochastic volatility are necessary our research shows that swaptions and even swaption straddles can be well hedged with libor bonds alone we examine the potential benefits of looking outside the libor market for factors that might impact swaption prices without impacting swap rates and find them to be minor indicating that the swaption market is well integrated with the libor swap market

stochastic volatilities and correlations of bond yields i develop an interest rate model with separate factors driving innovations in bond yields and their covariances it features a flexible and tractable affine structure for bond covariances maximum likelihood estimation of the model with panel data on swaptions and discount bonds implies pricing errors for swaptions that are almost always lower than half of the bid ask spread furthermore market prices of interest rate caps do not deviate significantly from their no arbitrage values implied by the swaptions under the model these findings support the conjectures of collin dufresne and goldstein 2003 dai and singleton 2003 and jagnnathan kaplin and sun 2003

broad bills or particularistic policy historical patterns in american state legislatures when do lawmakers craft broad policies and when do they focus on narrow legislation tailored to a local interest we investigate this question by exploring historical variation in the types of bills produced by american state legislatures drawing on a new database of 165 000 bills covering sessions over 120 years in thirteen different states we demonstrate the surprising prominence of particularistic bills affecting a specific legislator s district we then develop and test a theory linking the goals of legislators to their propensity to introduce district bills rather than broad legislation we find that consistent with our predictions politicians are more likely to craft policies targeted to a particular local interest when a legislature is dominated by one party or when it pays its members relatively high salaries these findings provide empirical support for key s 1949 thesis that one party politics descends into factionalism and undermines the making of broad public policy w hen lawmakers consider their legislative agendas they face a choice between introducing broad bills addressing major public policy needs and pushing for particularistic policies to meet the electoral demands of their districts or coreconstituencies thisdecisionoftensetstheirpolicy goals against their political ambitions forcing them to trade off among the competing priorities that fenno 1973 1978 and mayhew 1974 outline in making this decision legislators must consider the structure of their house the incentives provided by that structure and their own place in the chamber s power struggles how they resolve the tension between common policy considerations and personal electoral needs is at the root of legislative action the aggregation of individual decisions about the mix of legislation that each will pursue has important consequences for the balance of public and particularistic goods that the political system as a whole will produce analyzed theoretically

time changed levy libor market model pricing and joint estimation of the cap surface and swaption cube we propose a novel time changed levy libor london interbank offered rate market model for jointly pricing of caps and swaptions the time changes are split into three components the first component allows matching the volatility term structure the second generates stochastic volatility and the third accommodates for stochastic skew the parsimonious model is flexible enough to accommodate the behavior of both caps and swaptions for the joint estimation we use a comprehensive data set spanning the financial crisis of 2007 2010 we find that even during this period neither market is as fragmented as suggested by the previous literature

nonparametric estimation of state price densities implicit in interest rate cap prices based on a multivariate extension of the constrained locally polynomial estimator of ait sahalia and duarte 2003 we provide one of the first nonparametric estimates of probability densities of libor rates under forward martingale measures and state price densities spds implicit in interest rate cap prices the forward densities and spds depend significantly on the slope and volatility of libor rates and mortgage markets activities have strong impacts on the shape of the forward densities the spds exhibit a pronounced u shape as a function of future libor rates suggesting that the state prices are high at both extremely low and high interest rates which tend to be associated with recessions and periods of high inflation respectively our results provide nonparametric evidence of unspanned stochastic volatility and suggest that the unspanned factors could be partly driven by activities in the mortgage markets the author 2009 published by oxford university press on behalf of the society for financial studies all rights reserved for permissions please e mail journals permissions oxfordjournals org oxford university press

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

policy preferences and policy change dynamic responsiveness in the american states 1936 2014 using eight decades of data we examine the magnitude mechanisms and moderators of dynamic responsiveness in the american states we show that on both economic and especially social issues the liberalism of state publics predicts future change in state policy liberalism dynamic responsiveness is gradual however large policy shifts are the result of the cumulation of incremental responsiveness over many years partisan control of government appears to mediate only a fraction of responsiveness suggesting that contrary to conventional wisdom responsiveness occurs in large part through the adaptation of incumbent officials dynamic responsiveness has increased over time but does not seem to be influenced by institutions such as direct democracy or campaign finance regulations we conclude that our findings though in some respects normatively ambiguous on the whole paint a reassuring portrait of statehouse democracy

auction failures and the market for auction rate securities abstract the market for auction rate securities ars made headlines during the second week of february 2008 when auctions at which the bonds interest rates reset experienced a wave of failures contrary to headlines that attribute the failures to a frozen market or investors irrationality we find that 1 even at their height less than 50 of ars experienced auction failures 2 the likelihood of auction failure was directly related to the level of the bonds maximum auction rates 3 the implied market clearing yields of bonds with failed auctions were significantly above their maximum auction rates and 4 ars yields were generally higher than yields of various cash equivalent investment alternatives we infer that investors priced the possibility of auctions failures into ars yields and rationally declined to bid for bonds for which required market yields exceeded their maximum auction rates

the strength of issues using multiple measures to gauge preference stability ideological constraint and issue voting a venerable supposition of american survey research is that the vast majority of voters have incoherent and unstable preferences about political issues which in turn have little impact on vote choice we demonstrate that these findings are manifestations of measurement error associated with individual survey items first we show that averaging a large number of survey items on the same broadly defined issue area for example government involvement in the economy or moral issues eliminates a large amount of measurement error and reveals issue preferences that are well structured and stable this stability increases steadily as the number of survey items increases and can approach that of party identification second we show that once measurement error has been reduced through the use of multiple measures issue preferences have much greater explanatory power in models of presidential vote choice again approaching that of party identification

unemployment and recruitment with heterogeneous labor this paper describes the equilibrium wage distribution and unemployment rate when firms recruit search for employees a model in which firms inability to distinguish workers who refuse job offers increases their expected recruiting costs is contrasted with one in which indistinguishable low productivity workers decrease firms expected gains from hiring in both work force heterogeneity enhances search uncertainty firms recruit less intensively than otherwise and so the equilibrium unemployment rate rises heterogeneity reflects searchers incomplete knowledge of desirable trading partners locations and will likely be a confounding influence and source of unemployment in large economies with imperfectly observable sector specific shocks

bank liquidity providing in a real synergy management under a cap based valuation since banks often lend via commitments their lending and deposit taking may be two manifestations of one primitive function the provision of liquidity on demand we explore this function under a cap based valuation we find that i the strike price of the cap based valuation increases the bank s liquid asset holdings by increasing its loan rate and loan commitment rate with the strategic rate adjustment complements and decreases the bank s external finance need by increasing its deposit rate when the bank realizes a less risky state of the world and ii the number of caplet days decreases the bank s liquid asset holdings by decreasing its loan rate and loan commitment rate with the strategic rate adjustment complements and the strategic timing substitutes and increases the bank s external finance need by decreasing its deposit rate with the strategic timing substitutes when the bank realizes a more risky state our findings provide alternative explanations concerning the bank s liquidity funct

f o b pricing versus uniform delivered pricing a welfare analysis in a stochastic environment abstract under imperfect information but otherwise competitive assumptions spatial market equilibria are examined for two pricing structures under f o b pricing buyers face a price that reflects exactly the transportation cost between sellers and themselves under uniform delivered pricing u d p the seller charges the same price to all buyers inclusive of delivery under both buyers know only of sellers from whom they received ads sent randomly by sellers it is found that u d p equilibria may exist when f o b equilibria do not but not conversely also f o b equilibria are not always welfare superior to u d p ones these equilibria are not robust a new firm often succeeds in penetrating a market using a different pricing structure

on correlation and default clustering in credit markets we establish markovian models in the heath jarrow and morton 1992 paradigm that permit an exponential affine representation of riskless and risky bond prices while offering significant flexibility in the choice of volatility structures estimating models in our family is typically no more difficult than in the workhorse affine family besides diffusive and jump induced default correlations defaults can impact the credit spreads of surviving firms allowing for a greater clustering of defaults numerical implementations highlight the importance of incorporating interest rate credit spread correlations credit spread impact factors and the full credit spread curve when building a unified framework for pricing credit derivatives the author 2010 published by oxford university press on behalf of the society for financial studies all rights reserved for permissions please e mail journals permissions oxfordjournals org oxford university press

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

expectation puzzles time varying risk premia and dynamic models of the term structure abstract linear projections of returns on the slope of the yield curve have contradicted the implications of the traditional expectations theory this paper shows that these findings are not puzzling relative to a large class of richer dynamic term structure models specifically we match all the key empirical findings reported by fama and bliss 1987 american economic review 77 4 680 692 and campbell and shiller 1991 review of economic studies 58 495 514 among others within large subclasses of affine and quadratic gaussian term structure models additionally we show that certain risk premium adjusted projections of changes in yields on the slope of the yield curve recover the coefficients of unity predicted by the models key to this matching are parameterizations of the market prices of risk that let the risk factors affect the market prices of risk directly and not only through factor volatilities the risk premiums have a simple form consistent with fama s findings on the predictability of forward rates and are also shown to be consistent with interest rate feedback rules used by a monetary authority in setting monetary policy

the dynamics of state policy liberalism 1936 2014 applying a dynamic latent variable model to data on 148 policies collected over eight decades 1936 2014 we produce the first yearly measure of the policy liberalism of u s states our dynamic measure of state policy liberalism marks an important advance over existing measures almost all of which are purely cross sectional and thus cannot be used to study policy change we find that in the aggregate the policy liberalism of u s states steadily increased between the 1930s and 1970s and then largely plateaued the policy liberalism of most states has remained stable in relative terms though several states have shifted considerably over time we also find surprisingly little evidence of multidimensionality in state policy outputs our new estimates of state policy liberalism have broad application to the study of political development representation accountability and other important issues in political science abstract from author

limits of arbitrage theory and evidence from the mortgage backed securities market limits of arbitrage theories hypothesize that the marginal investor in a particular asset market is a specialized arbitrageur rather than a diversified representative investor we examine the mortgage backed securities mbs market in this light we show that the risk of homeowner prepayment which is a wash in the aggregate is priced in the mbs market the covariance of prepayment risk with aggregate wealth implies the wrong sign to match the observed prices of prepayment risk the price of risk is better explained by a kernel based on mbs market wide specific risk consistent with the specialized arbitrageur hypothesis a number of recent limits of arbitrage theories predict that the distressed liquidation of assets by hedge funds results in a large drop in asset prices see for example shleifer and vishny 1997 kyle and xiong 2001 gromb and vayanos 2002 geanakoplos 2003 or he and krishnamurthy 2006 these theories are often referenced in explaining episodes of market illiquidity and falling asset prices such as the events during the fall of 1998 in traditional asset pricing theory the marginal investor in every asset market is the same broadly diversified representative investor thus a hedge fund liquidating 200 billion of mortgage backed securities finds a large pool of ready buyers comparable to the entire capital market and the liquidation does not affect expected returns because the representative investor acts quickly to eliminate excess returns according to the limits of arbitrage theory on the other hand the marginal investor in a particular asset market is an investor who specializes in that market in this case liquidations can have large effects on prices given that the relevant set of buyers is a smaller specialized pool of investors

a multifactor spot rate model for the pricing of interest rate derivatives we propose a multifactor model in which the spot rate libor follows a lognormal process with a stochastic conditional mean under the risk neutral measure in addition to the spot rate factor the second factor is related to the premium of the first futures rate over the spot libor similarly the third factor is related to the premium of the second futures rate over the first futures rate we calibrate the model to the initial term structure of futures rates and to the implied volatilities of interest rate caplets we then apply the model to price interest rate derivatives such as european and bermudan style swaptions and yieldspread options the model can be employed to price more complex interest rate derivatives such as path dependent derivatives or multi currency dependent derivatives because of its markovian property

equities of scope as merger incentives under capital regulation narrow versus synergy banking valuation abstractthe call options theory of corporate security valuation is applied to narrow banking contingent claims of one bank while the cap options theory is applied to synergy banking contingent claims of another bank this article investigates efficiency gains specified as equities of scope associated with the likelihood of the two banks involved in merger under capital regulation we find that merger incentives are encouraged when the narrowing banking is conducted by the consolidated bank whereas discouraged when the synergy banking is conducted raising bank capital requirement leads to an increased interest margin of the consolidated bank with the narrow banking valuation however to a decreased margin of the consolidated bank with the synergy banking valuation an increase in the capital regulation reduces the merger incentives in the narrow banking valuation whereas increases the merger disincentive in the synergy banking valuation these findings are consistent with the organizational theory that

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

unspanned stochastic volatility evidence from hedging interest rate derivatives most existing dynamic term structure models assume that interest rate derivatives are redundant securities and can be perfectly hedged using solely bonds we find that the quadratic term structure models have serious difficulties in hedging caps and cap straddles even though they capture bond yields well furthermore at the money straddle hedging errors are highly correlated with cap implied volatilities and can explain a large fraction of hedging errors of all caps and straddles across moneyness and maturities our results strongly suggest the existence of systematic unspanned factors related to stochastic volatility in interest rate derivatives markets

representation in municipal government municipal governments play a vital role in american democracy as well as in governments around the world despite this little is known about the degree to which cities are responsive to the views of their citizens in the past the unavailability of data on the policy preferences of citizens at the municipal level has limited scholars ability to study the responsiveness of municipal government we overcome this problem by using recent advances in opinion estimation to measure the mean policy conservatism in every u s city and town with a population above 20 000 people despite the supposition in the literature that municipal politics are non ideological we find that the policies enacted by cities across a range of policy areas correspond with the liberal conservative positions of their citizens on national policy issues in addition we consider the influence of institutions such as the presence of an elected mayor the popular initiative partisan elections term limits and at large elections our results show that these institutions have little consistent impact on policy responsiveness in municipal government these results demonstrate a robust role for citizen policy preferences in determining municipal policy outcomes but cast doubt on the hypothesis that simple institutional reforms enhance responsiveness in municipal governments
