a review of the recent empirical literature on displaced workers this article reviews the empirical literature on job displacement job displacement is widespread and strongly countercyclical tending to peak during economic downturns but concentrated in indus

some empirical evidence on the effects of shocks to monetary policy on exchange rates this paper investigates the effects of shocks to u s monetary policy on exchange rates we consider three measures of these shocks orthogonalized shocks to the federal funds rate orthogonalized shocks to the ratio of nonborrowed to total reserves and changes in the romer and romer index of monetary policy in sharp contrast to the literature we find substantial evidence of a link between monetary policy and exchange rates specifically according to our results a contractionary shock to u s monetary policy leads to i persistent significant appreciations in u s nominal and real exchange rates and ii significant persistent deviations from uncovered interest rate parity in favor of u s interest rates

mean reversion in real exchange rates evidence and implications for forecasting abstract the stationarity of real exchange rates over the recent flexible exchange rate period is an issue that has long bedeviled researchers in international finance using a constrained multivariate framework this paper provides the strongest evidence yet that real exchange rates were mean reverting over the 1973 93 period we also investigate shifts in long run real exchange rates which may be important for the purpose of forecasting out of sample forecasting shows that the random walk model is outperformed by a mean stationary model especially at long horizons in addition there are substantial forecasting benefits from using a multivariate approach

interrupted work careers depreciation and restoration of human capital the quantitative effects and even the existence of a human capital depreciation phenomenon have been a subject of controversy in the recent literature prior work however was largely cross sectional and the longitudinal dimension if any was retrospective using longitudinal panel data on married women in nls we have now established that real wages at reentry are indeed lower than at the point of labor force withdrawal and the decline in wages is greater the longer the interruption another striking finding is a relatively rapid growth in wages after the return to work this rapid growth appears to reflect the restoration or repair of previously eroded human capital the phenomenon of depreciation and restoration is also visible in data for immigrants to the united states however while immigrants eventually catch up with and often surpass natives returnees from the nonmarket do not fully restore their earnings potential

seasonal flutuations and equilibrium models of exchange rate most of the evidence on dynamic equilibrium exchange rate models is based on seasonally adjusted consumption data equilibrium models have not worked well in explaining the actual exchange rate however the use of seasonally adjusted data might be responsible for the spurious rejection of the model this article presents a new equilibrium model for the exchange rates that incorporates seasonal preferences the fit of the model to the data is evaluated for five industrialized countries using seasonally unadjusted data our findings indicate that a model with seasonal preferences can generate monthly time series of the exchange rate without seasonality even when the variables that theoretically determine the exchange rate show clear seasonal behaviours further the model can generate theoretical exchange rates with the same order of integration than actual exchange rates and in some cases with the same stochastic trend

liquidity and exchange rates abstract we present a two country extension of lucas s 1988a work on cash in advance constraints in asset markets in the model there is temporary separation between the goods and asset markets and money is used for transactions in both we first find that the exchange rate level depends on the share of money used for asset transactions a greater share appreciates the currency second stochastic open market operations increasing the domestic bonds supply appreciate the domestic currency third the liquidity effects of bond supply shocks cause an excess volatility of nominal exchange rates even when their fundamental value is constant

an exploration in the theory of exchange rate regimes three exchange rate regimes a float a one sided peg and a cooperative peg are evaluated and compared in terms of efficiency and welfare levels the framework of analysis embodies country specific monies with the money of each country being used to transact in its commodity markets and its currency denominated bonds welfare levels depend only on consumption levels in the presence of perfect foresight all equilibrium allocations are pareto efficient in a floating exchange rate regime the perfect foresight equilibrium allocation coincides with an equilibrium of a costless barter economy the same result holds in a one sided peg if the pegging country s exchange rate stabilizing authority breaks even over time in a cooperative peg regime there is a different equilibrium allocation for each combination of exchange rate levels and monetary policies problems of policy coordination and conflicts in desired monetary policies are discussed

overwork and the slow convergence in the gender gap in wages despite rapid changes in women s educational attainment and continuous labor force experience convergence in the gender gap in wages slowed in the 1990s and stalled in the 2000s using cps data fr

the impact of local unemployment rates on reservation wages and the duration of search for a job evidence about the relationship of local unemployment rates and individuals reservation wages and duration of search for a job if unemployed is sparse and mixed this study uses us data from the panel study of income dynamics psid to test whether relatively high local unemployment rates reduce the reservation wages of area residents or increase the duration of search labour search theory provides the grounding for the sample selection corrected simultaneous equations econometric model in neither ols nor 2sls results is evidence found that local unemployment rates affect either reservation wages or the duration of search these results suggest that policies targeted at alleviating unemployment should focus on increasing the demand for labour rather than hope that such policies will be beneficial if pursued in high unemployment areas because of their effects on labour force characteristics

analytical pricing of discrete arithmetic asian options with mean reversion and jumps abstract empirical evidence indicates that commodity prices are mean reverting and exhibit jumps as some commodity option payoffs involve the arithmetic average of historical commodity prices we derive an analytical solution to arithmetic asian options under a mean reverting jump diffusion process the analytical solution is implemented with the fast fourier transform based on the joint characteristic function of the terminal asset price and the realized average value we also examine the accuracy and computational efficiency of the proposed method through numerical studies

long term swings and seasonality in energy markets abstract this paper introduces a two factor continuous time model for commodity pricing under the assumption that prices revert to a stochastic mean level which shows smooth periodic fluctuations over long periods of time we represent the mean reversion price by a fourier series with a stochastic component we also consider a seasonal component in the price level an essential characteristic of many commodity prices which we represent again by a fourier series we obtain analytical pricing expressions for futures contracts using futures price data on natural gas we provide evidence on the presence of long term fluctuations and show how to estimate the long term component simultaneously with a seasonal component using the kalman filter we analyse the in sample and out of sample empirical performance of our pricing model with and without a seasonal component and compare it with schwartz and smith 2000 model our findings show the in sample and out of sample superiority of our model with seasonal fluctuations thereby providing a simple and powerful tool for portfolio management risk management and derivative pricing

mean reversion in g 10 nominal exchange rates according to conventional wisdom industrial country floating exchange rates contain unit roots sur tests on panels of monthly group of ten g 10 log nominal rates reject the null of unit roots for various samples over the current float with significance levels from 0 5 to 15 on average in out of sample forecasts mean reversion models beat random walks significantly in some forecast periods for monthly data the range of expected usd dem appreciation rates exceeds 15 per year in the mean reversion model mean reversion places strong restrictions on international models over the sample period the g 10 had to run monetary policies consistent with stable long run nominal rates

variance swap with mean reversion multifactor stochastic volatility and jumps abstract this paper examines variance swap pricing using a model that integrates three major features of financial assets namely the mean reversion in asset price multi factor stochastic volatility sv and simultaneous jumps in prices and volatility factors closed form solutions are derived for vanilla variance swaps and gamma swaps while the solutions for corridor variance swaps and conditional variance swaps are expressed in a one dimensional fourier integral the numerical tests confirm that the derived solution is accurate and efficient furthermore empirical studies have shown that multi factor sv models better capture the implied volatility surface from option data the empirical results of this paper also show that the additional volatility factor contributes significantly to the price of variance swaps hence the results favor multi factor sv models for pricing variance swaps consistent with the implied volatility surface

optimizing bounds on security prices in incomplete markets does stochastic volatility specification matter we extend and generalize some results on bounding security prices under two stochastic volatility models that provide closed form expressions for option prices in detail we compute analytical expressions for benchmark and standard good deal bounds for both models our findings show that our benchmark results generate much tighter bounds a deep analysis of the properties of option prices and bounds involving a sensitivity analysis and analytical derivation of greeks for both option prices and bounds is also presented these results provide strong practical applications taking into account the relevance of pricing and hedging strategies for traders financial institutions and risk managers

do employers use unemployment as a sorting criterion when hiring evidence from a field experiment the stigma associated with long term unemployment spells could create large inefficiencies in labor markets while the existing literature points toward large stigma effects it has proven difficult to estimate causal relationships using data from a field experiment we find that long term unemployment spells in the past do not matter for employers hiring decisions suggesting that subsequent work experience eliminates this negative signal nor do employers treat contemporary short term unemployment spells differently suggesting that they understand that worker firm matching takes time however employers attach a negative value to contemporary unemployment spells lasting at least nine months providing evidence of stigma effects

a note on the determinants of unexpected exchange rate movements abstract in this paper we study the relative importance of surprises in fundamentals in explaining unexpected exchange rate movements employing a unique survey dataset that contains matched exchange rate and interest rate expectations we are able to derive a number of interesting conclusions a variance decomposition of unexpected exchange rate movements into various components reveals that interest rate news is relatively unimportant but that changes in perceptions about risk premia and more importantly revisions of expectations with regard to future exchange rate levels are crucial in explaining unexpected exchange rate movements

option pricing with mean reversion and stochastic volatility many underlying assets of option contracts such as currencies commodities energy temperature and even some stocks exhibit both mean reversion and stochastic volatility this paper investigates the valuation of options when the underlying asset follows a mean reverting lognormal process with stochastic volatility a closed form solution is derived for european options by means of fourier transform the proposed model allows the option pricing formula to capture both the term structure of futures prices and the market implied volatility smile within a unified framework a bivariate trinomial lattice approach is introduced to value path dependent options with the proposed model numerical examples using european options american options and barrier options demonstrate the use of the model and the quality of the numerical scheme

job matching and the wage distribution this paper brings together the microeconomic labor and the macroeconomic equilibrium views of matching in labor markets we nest a job matching model a la jovanovic 1984 into a mortensen and pissarides 1994 type equilibrium search environment the resulting framework preserves the implications of job matching theory for worker turnover and wage dynamics and it also allows for aggregation and general equilibrium analysis we obtain two new equilibrium implications of job matching and search frictions for wage inequality first learning about match quality and worker turnover map gaussian output noise into an ergodic wage distribution of empirically accurate shape unimodal skewed with a paretian right tail second high idiosyncratic productivity risk hinders learning and sorting and reduces wage inequality the equilibrium solutions for the wage distribution and for the aggregate worker flows quits to unemployment and to other jobs displacements hires provide the likelihood function of the model in closed form

time varying risk interest rates and exchange rates in general equilibrium under mild assumptions the data indicate that time varying risk is the primary force driving nominal interest rate differentials on currency denominated bonds this finding is an immediate implication of the fact that exchange rates are roughly random walks a general equilibrium monetary model with an endogenous source of risk variation a variable degree of asset market segmentation can produce key features of actual interest rates and exchange rates in this model the endogenous segmentation arises from a fixed cost for agents to exchange money for assets as inflation varies so does the benefit of asset market participation and that changes the fraction of agents participating these effects lead the risk premium to vary systematically with the level of inflation this model produces variation in the risk premium even though the fundamental shocks have constant conditional variances

liquidity models in open economies theory and empirical evidence abstract this paper presents an overview of recent theoretical and empirical research on liquidity models in open economies this is a class of optimizing models where money has effects on real asset prices and economic activity without relying on the ad hoc assumption of price wage stickiness the non neutrality of money derives from a temporary segmentation between goods and asset markets after surveying the theoretical literature on liquidity models we present empirical evidence based on var econometric techniques for the seven major industrial countries such evidence is shown to be consistent with the main implications of the liquidity models

money and exchange rates in the grossman weiss rotemberg model abstract we analyze the impact of monetary policy on inflation interest rates and exchange rates in a model with segmented asset markets developed by grossman and weiss 1983 and rotemberg 1984 1985 we find parameters for which real and nominal exchange rates in this model are 1 much more volatile than interest rates inflation rates and money growth rates 2 highly correlated with each other and 3 highly persistent while this model fails to match the data in other important respects it illustrates a potentially useful approach to modelling exchange rate behavior

pricing and hedging path dependent options under the cev process much of the work on path dependent options assumes that the underlying asset price follows geometric brownian motion with constant volatility this paper uses a more general assumption for the asset price process that provides a better fit to the empirical observations we use the so called constant elasticity of variance cev diffusion model where the volatility is a function of the underlying asset price we derive analytical formulae for the prices of important types of path dependent options under this assumption we demonstrate that the prices of options which depend on extrema such as barrier and lookback options can be much more sensitive to the specification of the underlying price process than standard call and put options and show that a financial institution that uses the standard geometric brownian motion assumption is exposed to significant pricing and hedging errors when dealing in path dependent options

forward discount puzzle and liquidity effects some evidence from exchange rates among the united states canada and japan this paper empirically examines whether the interaction between foreign exchange markets and monetary markets can help to resolve the forward discount puzzle following the monetary models of lucas 1990 and fuerst 1992 we define as liquidity effects the negative impact of monetary injection on nominal interest rates temporary deviations from the standard euler equation the liquidity effect identified by these models weakens the linkage between current forward rates and expected future spot rates and improves on the standard rational expectations model that predicts a one to one correspondence between the two using time series of exchange rates among the united states canada and japan this paper shows that the liquidity measure identified above has an impact on forward premiums and that once the liquidity effect is taken into consideration the unbiased prediction of the forward discount rate is recovered to some extent in a theoretically consistent manner

floating exchange rates with liquidity constraints in financial markets abstract we construct a two country model in which there exist cash in advance constraints in commodity as well as in asset markets the seller s currency is used for transactions in commodity markets and the lender s money is used for transactions in the bond markets the exchange rate equation that emerges from this structure has a new feature it exhibits a bias towards depreciation of the borrowers currency we describe the equilibrium dynamics of this type of a world economy and show that it may exhibit cyclical movements

valuation of power plants abstract in this paper we develop continuous time stochastic control models for valuation and operation of three stylised types of power plants in an electricity market a renewable plant a conventional plant and a storage plant examples of these types of power plants are respectively wind turbines gas fired generation units and hydroelectric facilities we demonstrate how to derive analytical or quasi analytical solutions in spite of many details in modeling in particular we model uncertainty in electricity prices and in production input output when it is relevant for the technology considered input output is assumed to follow a diffusion process whereas the price process may include jumps our models account for special characteristics of the technologies including a non normal distribution of wind speeds as well as start up and shut down costs of thermal units we use our models to assess the impact of conjectured future market conditions such as increasing average price level price volatility and correlation between renewable production and electricity prices

wavelet based option pricing an empirical study abstract in this paper we scrutinize the empirical performance of a wavelet based option pricing model which leverages the powerful computational capability of wavelets in approximating risk neutral moment generating functions we focus on the forecasting and hedging performance of the model in comparison with that of popular alternative models including the stochastic volatility model with jumps the practitioner black scholes model and the neural network based model using daily index options written on the german dax 30 index from january 2009 to december 2012 our results suggest that the wavelet based model compares favorably with all other models except the neural network based one especially for long term options hence our novel wavelet based option pricing model provides an excellent nonparametric alternative for valuing option prices

duration dependence and labor market conditions evidence from a field experiment this article studies the role of employer behavior in generating negative duration dependence the adverse effect of a longer unemployment spell by sending fictitious resumes to real job postings in 100 u s cities our results indicate that the likelihood of receiving a callback for an interview significantly decreases with the length of a worker s unemployment spell with the majority of this decline occurring during the first eight months we explore how this effect varies with local labor market conditions and find that duration de pendence is stronger when the local labor market is tighter this result is consistent with the prediction of a broad class of screening models in which employers use the unemployment spell length as a signal of unobserved productivity and recognize that this signal is less informative in weak labor markets jel code j64

one factor interest rate models and the valuation of interest rate derivative securities this paper compares different approaches to developing arbitrage free models of the term structure it presents a numerical procedure that can be used to construct a wide range of one factor models of the short rate that are both markov and consistent with the initial term structure of interest rates

welfare states and the scar effects of unemployment a comparative analysis of the united states and west germany1 the article examines whether through supporting workers search for adequate reemployment the decommodification achieved by welfare state transfers reduces the longer run scar effects of unemployment drawing on employment history data from the survey of income and program participation and the german socio economic panel the analysis establishes positive effects of unemployment benefits on workers post unemployment jobs workers risks of incurring severe earnings losses of experiencing occupational mobility and of entering unstable job arrangements are considerably reduced in both the united states and west germany as workers face constrained choices in labor markets however this institutional protection of workers economic status comes at the economic cost of prolonged unemployment simulation analyses suggest that higher benefit coverage alone might account for up to 20 of the smaller cumulative disadvantages associated with unemployment for german workers

money and interest in a cash in advance economy the authors analyze an aggregative general equilibrium model in which the use of money is motivated by a cash in advance constraint applied to purchases of a subset of consumption goods the system is subject to both real and monetary shocks which are economy wide and observed by all they develop methods for verifying the existence of characterizing and explicitly calculating equilibria copyright 1987 by the econometric society

public policy in a model of long term unemployment this paper considers a model in which the unemployed have to incur a cost to maintain their skills if whether they have done so is not observable the economy has multiple equilibria supported by self fulfilling beliefs on the part of the employers one of these equilibria which we argue is more likely to arise has equilibrium discrimination against the long term unemployed who in response decide to let their skills atrophy as a result in this equilibrium the exit probabilities from unemployment are duration dependent it is shown that equilibrium discrimination survives even if workers are allowed to accept negative wages at the beginning of the employment relation since this equilibrium is highly inefficient constructive government action in the form of positive discrimination subsidies and labour market policies are suggested to correct the market failures however subsidies and positive discrimination by private firms are shown not to have beneficial effects labour market policies in the form of retraining of the long term unemployed are beneficial but reduce the likelihood of a switch to the pareto preferred equilibrium the most useful policy appears to be a limited form of positive discrimination by a government sector

currency option pricing with mean reversion and uncovered interest parity a revision of the garman kohlhagen model abstract we consider a model for the pricing of currency options where the logarithm of the exchange rate exhibits mean reversion i e follows the omstein uhlenbeck process we mention reasons why exchange rates could exhibit mean reversion the domestic and foreign short interest rates are related to the logarithm of the exchange rate through uncovered interest parity under these assumptions we derive formulas for the value of a european currency option from the point of view of both domestic and foreign investors we also derive formulas for options on forward and futures contracts we compare option values computed by means of the garman kohlhagen model with corresponding results from our model it appears that our model cannot explain all instances of mispricing of currency options by the garman kohlhagen model which have been reported by previous authors the main virtue of our paper however is that we derive a simple model which incorporates clear theoretical relationship between the exchange rate and the domestic and foreign interest rates

forecasting the volatility of crude oil futures using intraday data abstract we use the information in intraday data to forecast the volatility of crude oil at a horizon of 1 66 days using a variety of models relying on the decomposition of realized variance in its positive or negative semivariances part and its continuous or discontinuous part jumps we show the importance of these decompositions in predictive in sample regressions using a number of specifications nevertheless an important empirical finding comes from an out of sample analysis which unambiguously shows the limited interest of considering these components overall our results indicates that a simple autoregressive specification mimicking long memory and using past realized variances as predictors does not perform significantly worse than more sophisticated models which include the various components of realized variance

an fft network for levy option pricing abstract this paper develops a simple network approach to american exotic option valuation under levy processes using the fast fourier transform fft the forward shooting grid fsg technique of the lattice approach is then generalized to expand the fft network to accommodate path dependent variables this network pricing approach is applicable to all levy processes for which the characteristic function is readily available in other words the log value of the underlying asset can follow finite activity or infinite activity levy processes with the powerful computation of fft the proposed network has a negligible additional computational burden compared to the binomial tree approach the early exercise policy and option values in the continuation region are determined in a way very similar to that of the lattice approach numerical examples using american style barrier lookback and asian options demonstrate that the fft network is accurate and efficient

vix derivatives hedging and vol of vol risk we study the empirical hedging performance of alternative vix option pricing models recent advances in the literature find evidence of asymmetric volatility of volatility similar to the leverage effect in equity markets stochastic mean reversion and jumps using such findings in our model framework we show that while sophisticated models have superior pricing performance and can explain a range of stylized facts in the vix derivatives market their hedging performance is inferior to a simple black model hedge we also study the empirical performance of regime dependent hedge ratio adjustments commonly applied in equity markets

penalized or protected gender and the consequences of nonstandard and mismatched employment histories millions of workers are employed in positions that deviate from the full time standard employment relationship or work in jobs that are mismatched with their skills education or experience yet little is known about how employers evaluate workers who have experienced these employment arrangements limiting our knowledge about how part time work temporary agency employment and skills underutilization affect workers labor market opportunities drawing on original field and survey experiment data i examine three questions 1 what are the consequences of having a nonstandard or mismatched employment history for workers labor market opportunities 2 are the effects of nonstandard or mismatched employment histories different for men and women and 3 what are the mechanisms linking nonstandard or mismatched employment histories to labor market outcomes the field experiment shows that skills underutilization is as scarring for workers as a year of unemployment but that there are limited penalties for workers with histories of temporary agency employment additionally although men are penalized for part time employment histories women face no penalty for part time work the survey experiment reveals that employers perceptions of workers competence and commitment mediate these effects these findings shed light on the consequences of changing employment relations for the distribution of labor market opportunities in the new economy

mean reversion in equilibrium asset prices evidence from the futures term structure we use the term structure of futures prices to test whether investors anticipate mean reversion in spot asset prices the empirical results indicate mean reversion in each market we examine for agricultural commodities and crude oil the magnitude of the estimated mean reversion is large for example point estimates indicate that 44 percent of a typical spot oil price shock is expected to be reversed over the subsequent eight months for metals the degree of mean reversion is substantially less but still statistically significant we detect only weak evidence of mean reversion in financial asset prices in this study we provide evidence of mean reversion in the prices of several real and financial assets rather than examining evidence of ex post reversion using time series of asset prices we use price data from futures contracts with varying delivery horizons to test whether investors expect asset prices to revert this approach offers two advantages first since futures prices are readily available for many markets our procedure can be implemented for many assets including those for which reliable spot price data is elusive second there is little ambiguity as to the source of any mean reversion detected using our method subject only to the maintained assumption that the no arbitrage cost of carry condition holds our test detects mean reversion that is expected to occur in equilibrium but has no power to detect mean reversion resulting from noise or inefficiencies our methodology focuses on relations between price levels and the slope of the futures term structure defined as the change across delivery dates in the futures prices observed on a given trading date an inverse relation between prices and the futures term slope constitutes evidence that investors expect mean reversion in spot prices to illustrate initially assume there are no

commodity derivatives pricing with cointegration and stochastic covariances abstract empirically cointegration and stochastic covariances including stochastic volatilities are statistically significant for commodity prices and energy products to capture such market phenomena we develop a continuous time dynamics of cointegrated assets with a stochastic covariance matrix and derive the joint characteristic function of asset returns in closed form the proposed model offers an endogenous explanation for the stochastic mean reverting convenience yield the time series of spot and futures prices of wti crude oil and gasoline shows cointegration relationship under both physical and risk neutral measures the proposed model also allows us to fit the observed term structure of futures prices and calibrate the market implied cointegration relationship we apply it to value options on a single commodity and on multiple commodities

common currencies vs monetary independence we study the optimal monetary policy in a two country open economy model under two monetary arrangements a multiple currencies controlled by independent policy makers b common currencies with a centralized policy maker our findings suggest that i monetary policy competition leads to higher long term inflation and interest rates with large welfare losses ii the inflation bias and the consequent losses are larger when countries are unable to commit to future policies iii the welfare losses from higher long term inflation dominates the welfare costs of losing the ability to react optimally to shocks

ranking unemployment duration and wages it explores the implication of one central assumption when firms receive multiple acceptable applications they hire the worker who has been unemployed for the least amount of time this assumption ranking is contrasted with the assumption of random hiring no ranking by embodying this assumption in a model of the labour market with job creation destruction and matching the joint behaviour of unemployment the distribution of unemployment durations and wages are characterized the implication that the re employment prospects of employed workers were they to become unemployed are better than those of the currently unemployed appears to have been an important feature of european unemployment experience in the 1980 s this paper examines the effects of the composition of unemployment on wage determination it explores one central assumption when firms receive multiple acceptable applications they hire the worker who has been unemployed for the least amount of time we refer to this assumption as ranking and contrast it throughout to the assumption of random hiring or no ranking by embodying this assumption in a model of the labour market with job creation destruction and matching we characterize the joint behaviour of unemployment the distribution of unemployment durations and wages ranking has a number of important implications first in addition to the obvious result that the exit rate from unemployment is a decreasing function of duration we show that the effect of duration is stronger the higher the rate of unemployment second with the wage depending on the distributions of prospective unemployment durations the presence of long term unemployed per se has little effect on wages third looking at the relation between the wage and the aggregate level of unemployment and comparing ranking to the case of no ranking the wage moves less with the level of unemployment but more with the change in unemployment put simply ranking and no ranking models show exactly the same aggregate unemployment slightly different long run responses of wages to unemployment and sharply different wage dynamics the paper is organized as follows section i characterizes the matching process and derives a matching function based on an urn ball process with vacancies as urns and applications by unemployed workers as balls thus the distribution of applications per vacancy depends on aggregate unemployment and vacancies vacancies with at least one acceptable application are filled when a vacancy receives more than one acceptable application firms use a rule to choose among applicants thus the rule determines who is hired but does not affect the number of hires section ii uses this matching function in a model of the labour market with continual job creation and destruction and characterizes the equilibrium values of unemployment vacancies and hires

mean reversion in equilibrium asset prices this paper demonstrates that negative serial correlation in long horizon stock returns is consistent with an equilibrium model of asset pricing when investors display only a moderate desire to smooth their consumption commonly used measures of mean reversion in stock prices calculated from historical returns data nearly always lie within a 60 percent confidence interval of the median of the monte carlo distributions implied by the authors equilibrium model from this evidence the authors conclude that the degree of serial correlation in the data could plausibly have been generated by their model copyright 1990 by american economic association

a general framework for discretely sampled realized variance derivatives in stochastic volatility models with jumps abstract after the recent financial crisis the market for volatility derivatives has expanded rapidly to meet the demand from investors risk managers and speculators seeking diversification of the volatility risk in this paper we develop a novel and efficient transform based method to price swaps and options related to discretely sampled realized variance under a general class of stochastic volatility models with jumps we utilize frame duality and density projection method combined with a novel continuous time markov chain ctmc weak approximation scheme of the underlying variance process contracts considered include discrete variance swaps discrete variance options and discrete volatility options models considered include several popular stochastic volatility models with a general jump size distribution heston scott hull white stein stein hypergeometric 3 2 and 4 2 models our framework encompasses and extends the current literature on discretely sampled volatility derivatives and provides highly efficient and accurate valuation methods numerical experiments confirm our findings

the effects of unemployment and underemployment on employment opportunities results from a correspondence audit of the labor market for college graduates the authors use data from a resume audit to estimate the impact of unemployment and underemployment on the employment prospects of recent college graduates they find no statistical evidence linking unemployment spells of different durations to employment opportunities by contrast college graduates who are underemployed have callback rates that are 30 lower than those of applicants who are adequately employed the null effects associated with unemployment and the adverse effects associated with underemployment are robust across cities with relatively tight and loose labor market conditions internship experience obtained while completing one s degree substantially reduces the negative effects of underemployment the data support the proposition that employers view underemployment as a strong signal of lower expected productivity

open economy macroeconomics developments in theory and policy this paper views developments in open economy macroeconomics through the lens of the debate over european monetary unification the empirical tendency for nominal exchange rate regimes to affect the variability of nominal and real exchange rates alike can be rationalized by sticky price theories or models of asset market liquidity effects but plausible liquidity models have difficulty generating enough persistence to match the data thus the macroeconomic stabilization costs of forgoing the exchange rate realignment option seem pertinent it is argued that our theories of efficiencies due to a common currency remain unsatisfactory despite recent advances the paper concludes by reviewing theories of currency crisis

capital flows investment and exchange rates abstract this paper incorporates international capital flows into a two country monetary general equilibrium model of asset prices with investment and production we calculate theoretical covariances between investment the current account the exchange rate and the terms of trade these covariances depend upon the coefficient of relative risk aversion the magnitude and sign of a country s net international indebtedness other properties of tastes and technologies and the stochastic processes on disturbances to productivity and monetary growth rates international capital flows arise from changes in world wealth and its relative composition in foreign and domestic assets

financial market effects on aggregate money demand a bayesian analysis empirical researchers in aggregate money demand have long been concerned with the degree of substitutability between money and other capital assets and the impact on money holdings of financial markets developments despite the potential importance of financial market linkages to money demand empirical studies display substantial diversity in modeling these influences various econometric studies have found that money holdings may depend on short term debt returns bond yields and even the term structure of interest rates there is also evidence that stock market returns and measures of stock trading affect money holdings existing studies are limited in their evaluation of asset substitution patterns and other financial market effects because they look at a small subset of possible specifications

the welfare implications of foreign exchange intervention abstract this paper examines the welfare implications of foreign exchange intervention in a two country two currency general equilibrium model with limited participation in financial markets and cash in advance constraints on transactions both sterilized and nonsterilized intervention operations have significant impacts on the allocation of liquidity in international financial markets and therefore affect real economic activities the welfare effects of shocks to monetary policy sterilized and nonsterilized foreign exchange interventions are examined and compared the design of welfare maximizing intervention policy rules is also discussed
