strikes and holdouts in wage bargaining theory and data we develop a private information model of union contract negotiations in which disputes signal a firm s willingness to pay previous models have assumed that all labor disputes take the form of a strike yet a prominent feature of u s collective bargaining is the holdout negotiations often continue without a strike after the contract has expired production continues with workers paid according to the expired contract we analyze the union s decision to strike or hold out and highlight its importance to strike activity strikes are more likely to occur after a drop in the real wage or a decline in unemployment

answering the skeptics yes standard volatility models do provide accurate forecasts a voluminous literature has emerged for modeling the temporal dependencies in financial market volatility using arch and stochastic volatility models while most of these studies have documented highly significant in sample parameter estimates and pronounced intertemporal volatility persistence traditional ex post forecast evaluation criteria suggest that the models provide seemingly poor volatility forecasts contrary to this contention we show that volatility models produce strikingly accurate interdaily forecasts for the latent volatility factor that would be of interest in most financial applications new methods for improved ex post interdaily volatility measurements based on high frequency intradaily data are also discussed

information holdouts and land assembly abstract this paper solves for the equilibria of a land assembly game there are multiple perfect bayesian equilibria but only one involves no play of weakly dominated strategies the equilibrium has three important characteristics first the develop s bid is uninformative the counteroffers of the landowners depend therefore only on their priors second there is a holdout problem smaller landowners ask larger per acre prices for their land this means that when there are many landowners the price will be larger if there is an agreement and mutually beneficial agreements will more frequently be missed third when the asking prices of the landowners are strategic complements some landowners can be induced to accept a low bid because this leads other landowners to moderate their own asking prices

the informational content of implied volatility implied volatility is widely believed to be informationally superior to historical volatility because it is the markets forecast of future volatility but for s p 100 index options the most actively traded contract in the united states we find implied volatility in aggregate and across subsamples separated by maturity and strike price implied volatility has virtually no correlation with future volatility and it does not incorporate the information contained in recent observed volatility article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

sovereign debt restructuring since the early 1980 s patterns of emergingmarket finance have changed significantly greater integration of capital markets and a trend toward a greater use of direct lending through bonds has led to relatively decreased use of indirect finance through syndicated bank loans these changes have produced benefits to investors through opportunities for risk diversification and to emerging market sovereign borrowers by increasing the investor base the broadened investor base in bond financing however raises problems of coordination and collective action in the event of a sovereign borrower s default and restructuring now three parties are involved in determining the debt markdown required to produce solvency the debtor creditors and the global taxpayer through international financial institutions ifi s the complex relationships among the borrowers creditors and the global taxpayer have made restructuring obligations a costly and time consuming exercise especially with the possibility of holdouts both the sovereign borrower and its creditors have an incentive to avoid a restructuring in the hope of financial assistance from the global taxpayer sovereign governments may not undertake the politically painful steps involved in beginning a restructuring when there is always the hope that official assistance will be forthcoming creditors may not accept a reduction in the value of their claims also in the hope that official assistance will be forthcoming costs of postponed and disorderly restructurings are real and substantial delays in restructuring can drain a country s resources and increase the ultimate costs of restoring financial sustainability creditors bear a burden as well because the losses associated with the restructuring are reflected in values of

forecasting with quantitative methods the impact of special events in time series quantitative methods are very successful in producing baseline forecasts of time series however these models forecast neither the timing nor the impact of special events such as promotions or strikes in most of the cases the timing of such events is not known so they are usually referred as shocks economics or special events forecasting sometimes the timing of such events is known a priori i e a future promotion but even then the impact of the forthcoming event is hard to estimate forecasters prefer to use their own judgement for adjusting for forthcoming special events but human efficiency in such tasks has been found to be deficient this study after examining the relative performance of artificial neural networks anns multiple linear regression mlr and nearest neighbour nn approaches proposes an expert method which combines the strengths of regression and artificial intelligence

duration of sovereign debt renegotiation abstract in the period since 1990 sovereign debt renegotiations take an average of five years for bank loans but only one year for bonds we provide an explanation for this finding by highlighting one key difference between bank loans and bonds bank loans are rarely traded while bonds are heavily traded on the secondary market in our theory the secondary market plays a crucial information revelation role in shortening renegotiations consider a dynamic bargaining game with incomplete information between a government and creditors the creditors reservation value is private information and the government knows only its distribution delays in reaching agreements arise in equilibrium because the government uses costly delays to screen the creditors reservation value when the creditors trade on the secondary market the market price conveys information about their reservation value which lessens the information friction and reduces the renegotiation duration we find that the secondary market tends to increase the renegotiation payoff of the government but decrease that of the creditors while increasing the total payoff we then embed these renegotiation outcomes in a simple sovereign debt model to analyze the ex ante welfare implications the secondary market has the potential to increase the government ex ante welfare when the information friction is severe

stock index realized volatility forecasting in the presence of heterogeneous leverage effects and long range dependence in the volatility of realized volatility in this article we account for the presence of heterogeneous leverage effects and the persistence in the volatility of stock index realized volatility the heterogeneous autoregressive har realized volatility rv model is extended in order to account for asymmetric responses to negative and positive shocks occurring at distinct frequencies as well as for the long range dependence in the heteroscedastic variance of the residuals compared with established har and autoregressive fractionally integrated moving average arfima realized volatility models the proposed model exhibits superior in sample fitting as well as out of sample volatility forecasting performance the latter is further improved when the realized power variation rpv is used as a regressor while we show that our analysis is also robust against microstructure noise

conditional risk and return in asian emerging markets evidence from the banking sector previous studies reach no consensus on the relationship between risk and return using data from one market this study argues that the market factor should be noticed in assessing the risk return relationship in a partially integrated emerging market the analysis aims to provide new insight into the nature of the risk return relationship by a conditional factor garch m framework that controls for time series effects to investigate the banking sector in five asian emerging markets of china hong kong indonesia malaysia and taiwan during the period 1995 to 2004 finally the study provides evidence on these relations before and after the asian financial crisis of 1997 the results are generally consistent across the markets and with expectations and have implications for empirical assessments of the risk return relationship and diversification

the relation between implied and realized volatility abstract previous research finds the volatility implied by s p 100 index option prices to be a biased and inefficient forecast of future volatility and to contain little or no incremental information beyond that in past realized volatility in contrast we find that implied volatility outperforms past volatility in forecasting future volatility and even subsumes the information content of past volatility in some of our specifications our results differ from previous studies because we use longer time series and nonoverlapping data a regime shift around the october 1987 crash explains why implied volatility is more biased in previous work

an experimental study of the holdout problem in a multilateral bargaining game abstract when an economic exchange requires agreement by multiple independent parties the potential exists for an individual to strategically delay agreement in an attempt to capture a greater share of the surplus created by the exchange this holdout problem is a common feature of the land assembly literature because development frequently requires the assembly of multiple parcels of land we use experimental methods to examine holdout behavior in a laboratory bargaining game that involves multi person groups complementary exchanges and holdout externalities the results of six treatments that vary the bargaining institution number of bargaining periods and the cost of delay demonstrate that holdout is common across institutions and is on average a payoff improving strategy for responders both proposers and responders take a more aggressive initial bargaining stance in multi period bargaining treatments relative to single period treatments but take a less aggressive bargaining stance when delay is costly nearly all exchanges eventually occur in our multi period treatments leading to higher overall efficiency relative to the single period treatments both with and without delay costs

forecasting stock return variance toward an understanding of stochastic implied volatilities we examine the behavior of measured variances from the options market and the underlying stock market under the joint hypotheses that markets are informationally efficient and that option prices are explained by a particular asset pricing model forecasts from time series models of the stockreturn process should not have predictive content given the market forecast as embodied in option prices both in sample and out of sample tests suggest that this hypothesis can be rejected using simulations we show that biases inherent in the procedure we use to imply variances cannot explain this result thus we provide evidence inconsistent with the orthogonality restrictions of option pricing models that assume that variance risk is unpriced these results also have implicationsfor optimal variance forecast rules

predicting volatility in the foreign exchange market measures of volatility implied in option prices are widely believed to be the best available volatility forecasts in this article we examine the information content and predictive power of implied standard deviations isds derived from chicago mercantile exchange options on foreign currency futures the article finds that statistical time series models even when given the advantage of ex post parameter estimates are outperformed by isds isds however also appear to be biased volatility forecasts using simulations to investigate the robustness of these results the article finds that measurement errors and statistical problems can substantially distort inferences even accounting for these however isds appear to be too variable relative to future volatility it is widely believed that the volatility implied in option prices is the market s best estimate of future volatility after all if it were not one could devise a trading strategy that could generate profits by identifying mispriced options the purpose of this article is to investigate the information content and predictive power of volatility implied in options on foreign currencies the paper focuses on options on currency futures traded on the chicago mercantile exchange cme because of the depth and liquidity of cme futures and options traded side by side in the same market implied standard deviations isds allow for clean tests of the predictive power of implied volatilities early studies of the information content of isds have generally found that these contain substantial information for future volatility latane and rendleman 1976 chiras and manaster 1978 and beckers 1981 for example regress future volatility on the weighted implied volatility across a broad sample of chicago board options exchange cboe stocks and find that options contain volatility forecasts that are more accurate than historical measures 1 these studies performed shortly after the 1973 beginning of the cboe option market could only use a relatively short time span and therefore focused on cross sections rather than time series predictions

a closed form garch option valuation model this paper develops a closed form option valuation formula for a spot asset whose variance follows a garch p q process that can be correlated with the returns of the spot asset it provides the first readily computed option formula for a random volatility model that can be estimated and implemented solely on the basis of observables the single lag version of this model contains heston s 1993 stochastic volatility model as a continuous time limit empirical analysis on s p500 index options shows that the out of sample valuation errors from the single lag version of the garch model are substantially lower than the ad hoc black scholes model of dumas fleming and whaley 1998 that uses a separate implied volatility for each option to fit to the smirk smile in implied volatilities the garch model remains superior even though the parameters of the garch model are held constant and volatility is filtered from the history of asset prices while the ad hoc black scholes model is updated every period the improvement is largely due to the ability of the garch model to simultaneously capture the correlation of volatility with spot returns and the path dependence in volatility article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

restructuring sovereign debt this paper provides new empirical evidence relevant to the debate over the desirability of reforms to the way that financial markets and the international community deal with sovereign debt crises in particular given the ongoing opposition of investors and some sovereigns to greater use of collective action clauses cacs in emerging market bonds we present new evidence on the way that financial markets have priced the use or non use of cacs

is aggregation a problem for sovereign debt restructuring reform of the mechanisms and procedures through which problems of sovereign debt sustainability are resolved is at the centre of the effort to make the international financial system less crisis prone the purported difficulty of coordinating creditors holding distinct bond issues provides one basis for choosing among the reform proposals currently on the table we assess the significance of this difficulty the aggregation problem using evidence on the pricing of international bonds our evidence suggests that investors do perceive that aggregation has costs plausibly they worry most about difficulties of information sharing and coordination across issues when the debt in question is an obligation of a country with a significant perceived probability of having to restructure

foreign law bonds can they reduce sovereign borrowing costs abstract governments often issue bonds in foreign jurisdictions which can provide additional legal protection vis a vis domestic bonds this paper studies the effect of this jurisdiction choice on bond prices we test whether foreign law bonds trade at a premium compared to domestic law bonds we use the euro area 2006 2013 as a unique testing ground controlling for currency risk liquidity risk and term structure foreign law bonds indeed carry significantly lower yields in distress periods and this effect rises as the risk of a sovereign default increases these results indicate that in times of crisis governments can borrow at lower rates under foreign law

volatility forecasting by quantile regression quantile regression allows one to predict the volatility of time series without assuming an explicit form for the underlying distribution financial assets are known to have irregular return patterns not only the volatility but also the distribution functions themselves may vary with time so traditional time series models are often unreliable this study presents a new approach to volatility forecasting by quantile regression utilizing a uniformly spaced series of estimated quantiles the proposed method provides much more complete information on the underlying distribution without recourse to an assumed functional form based on an empirical study of seven stock indices using 16 years of daily return data the proposed approach produces better volatility forecasts for six of the seven indices

bond restructuring and moral hazard are collective action clauses costly abstract recent emerging market crises have prompted debate over the costs and benefits of collective action clauses cacs in bond contracts cacs may facilitate the restructuring of repayment terms in the event of financial distress proponents of cacs argue they should lower borrowing costs while opponents contend that they lead to moral hazard and increased borrowing costs this paper examines the pricing of bonds with and without cacs using data for both primary and secondary market yields and finds no evidence that the presence of cacs has increased yields for either higher or lower rated issuers

forecasting volatility of futures market the s p 500 and ftse 100 futures using high frequency returns and implied volatility we show that historical volatility from high frequency returns outperforms implied volatility when standardized returns by historical volatility tends to be normally distributed for the ftse 100 futures we find that historical volatility using high frequency returns outperforms implied volatility in forecasting future volatility however we find that implied volatility outperforms historical volatility in forecasting future volatility for the s p 500 futures the results also indicate that historical volatility using high frequency returns could be an unbiased forecast for the ftse 100 futures 1 we thank christopher lowes for his excellent research assistance

the holdout problem and urban sprawl experimental evidence abstract conventional wisdom as well as economic theory suggests it is more costly to reassemble fragmented land due to transactions costs and strategic bargaining costs both costs are expected to increase with the number of sellers inefficient allocation of land resources may result including property entropy parisi 2002 urban sprawl miceli and sirmans 2007 and deteriorating inner cities given the difficulty of observing actual values attached by buyers and sellers to land little empirical evidence exists to support the conventional wisdom and theoretical work we use experimental methods to examine transactions costs and strategic bargaining costs in a land assembly market game with one buyer 1 4 sellers and complementary exchanges the buyer s final earnings vary inversely with the number of sellers ceteris paribus indicating an incentive to purchase consolidated land delay costs reduce holdout but result in lower payoffs for both buyers and sellers competition between sellers reduces holdout and the buyer s total purchase price
