bond indenture provisions and the risk of corporate debt abstract this paper examines the effect of alternative bond indenture provisions on the allocation of risk among the firm s claimants the approach taken here differs from that of earlier studies in that risk allocation is examined while the firm s leverage in market value terms is held constant in this context four indenture provisions are examined 1 the time to maturity 2 the promised payment schedule 3 financing restrictions and 4 priority rules it is concluded that risk is transferred from stockholders to bondholders as the time to maturity and promised payment increase appropriately furthermore substitution of longer term debt for an equal amount of shorter term debt also increases the risk to bondholders while decreasing the risk to stockholders the analysis shows that a coupon bond can be represented by a unique discount bond with the same risk and value this permits the characterization of the effective maturity of a risky debt issue a concept analogous to the stochastic duration of a default free coupon bond these results are shown to be independent of the means used to finance the debt issue finally it is concluded that the relative risk associated with different bonds issued by the same firm cannot be determined by the structure of priority rules alone it is also necessary to consider the timing of the promised payments compared to that of the other debt issues in the firm s capital structure

a bayesian approach to modeling stock return volatility for option valuation new measures of stock return volatility are developed to increase the precision of stock option price estimates with bayesian statistical methods volatility estimates for a given stock are developed using prior information on the cross sectional patterns in return volatil ities for groups of stocks sorted on size financial leverage and trading volume call option values computed with the bayesian procedure generally improve prediction accuracy for market prices of call options relative to those computed using implied volatility standard historical volatility or even the actual ex post volatility that occurred during each option s life although the bayesian methods produce biased call price estimators they do reduce the systematic tendency of standard pricing approaches to overprice underprice options on high low volatility stocks little bias improvement is observed with respect to the time to maturity and moneyness of the call options

nominal income targeting in an open economy optimizing model abstract this paper presents simulation results regarding the performance of nominal income targeting a monetary policy rule that sets interest rates in response to deviations of nominal gdp growth from a target path the macroeconomic model is one in which agents solve dynamic optimization problems with rational expectations but in an environment with slow price adjustments in the present version consumption choices reflect habit formation and the economy is open to international flows of goods and securities when calibrated to quarterly us data the model s results suggest that nominal income targeting performs well in relation to inflation targeting and taylor rules

the transition to the knowledge economy labor market institutions and income inequality in advanced democracies the transition from fordism to the knowledge economy in the world s advanced democracies was underpinned by the revolution in information and communications technology ict the introduction and rapid diffusion of ict pushed up wages for college educated workers with complementary skills and allowed top managers and ceos to reap greater rewards for their own talents despite these common pressures income inequality did not rise to the same extent everywhere income in the anglo saxon countries remains particularly unequally distributed to shed new light on this puzzle the authors carry out a panel data analysis of eighteen oecd countries between 1970 and 2007 their analysis stands apart from the existing empirical literature by taking a comparative perspective the article examines the extent to which the relationship between the knowledge economy and income inequality is influenced by national labor market institutions the authors find that the expansion of knowledge employment is positively associated with both the 90 10 wage ratio and the income share of the top 1 percent but that these effects are mitigated by the presence of strong labor market institutions such as coordinated wage bargaining strict employment protection legislation high union density and high collective bargaining coverage the authors provide robust evidence against the argument that industrial relations systems are no longer important safeguards of wage solidarity in the knowledge economy

the davis bacon act an appraisal of recent studies the intensified controversy in recent years over the davis bacon act which requires the payment of prevailing wages on federally funded construction projects has resulted in several new studies of the effects of that act this invited paper reviews the evidence presented in these recent studies on several aspects of the act including how davis bacon wage determinations compare to local construction wages as measured by sources other than the act s administrators the effects of lags in the act s data gathering process and the savings that would result from calculating the prevailing rate as the arithmetic mean of local wages instead of the current use of the modal rate in most cases the authors conclude that although the cost studies to date have been faulty in several respects it is reasonably clear that davis bacon is unattractive on grounds of economic efficiency alone the question remains however whether these efficiency costs are offset partially or wholly by the possible equity benefits o

the role of credit in the great moderation a multivariate garch approach abstract during the great moderation financial innovation in the us increased the size and scope of credit flows supporting the growth of wealth we hypothesize that spending out of wealth came to finance a wider range of gdp components such that it smoothed gdp both these trends combined would be consistent with a decrease in the volatility of output we suggest testable implications in terms of both growth of credit and output and volatility of growth in a multivariate garch framework we test this view for home mortgages and residential investment we observe unidirectional causality in variance from total output residential investment and non residential output to mortgage lending before but not during the great moderation these findings are consistent with a role for credit dynamics in explaining the great moderation

skill biased technological change and rising wage inequality some problems and puzzles the recent rise in wage inequality is usually attributed to skill biased technical change sbtc associated with new computer technologies we review the evidence for this hypothesis focusing on the implications of sbtc for overall wage inequality and for changes in wage differentials between groups a key problem for the sbtc hypothesis is that wage inequality stabilized in the 1990s despite continuing advances in computer technology sbtc also fails to explain the evolution of other dimensions of wage inequality including the gender and racial wage gaps and the age gradient in the return to education

the effect of unions on the structure of wages a longitudinal analysis this paper studies the effects of unions on the structure of wages using an estimation technique that explicitly accounts for misclassification errors in reported union status and potential correlations between union status and unobserved productivity the econometric model is estimated separately for five skill groups using a large panel data set formed from the u s current population survey the results suggest that unions raise wages more for workers with lower levels of observed skills in addition the patterns of selection bias differ by skill group among workers with lower levels of observed skill unionized workers are positively selected whereas union workers are negatively selected from among those with higher levels of observed skill despite a large and sophisticated literature there is still substantial disagreement over the extent to which differences in the structure of wages between union and nonunion workers represent an effect of trade unions rather than a consequence of the nonrandom selection of unionized workers over the past decade several alternative approaches have been developed to control for unobserved heterogeneity between union and nonunion workers 2 one method that has been successfully applied in other areas of applied microeconometrics is the use of longitudinal data to measure the wage gains or losses of workers who change union status unfortunately longitudinal estimators are highly sensitive to measurement error even a small fraction of misclassified union status changes can lead to significant biases if the true rate of mobility between union and nonunion jobs is low this sensitivity led lewis 1986 to essentially dismiss the longitudinal evidence in his landmark survey of union wage effects in this paper i present some new evidence on the union wage effect based on a longitudinal estimator that explicitly accounts for misclassification errors in reported union status the estimator uses external information on union status misclassification rates along with the reduced form coefficients from a multi variate regression of wages on the observed sequence of union status indicators to isolate the causal effect of unions from any selection biases introduced by a correlation between union status and the permanent component of unobserved wage heterogeneity recognizing that unions may raise wages more or less for

risky business the decline of defined benefit pensions and firms shifting of risk since the early 1980s employment in the united states has undergone significant transformation as the large corporations that once safeguarded employees with stable jobs and rewards for loyalty have replaced these employment relationships with ones based on cost containment and flexibility one important consequence of these developments is that firms have abdicated their role as a critical risk bearer in society although evidence suggests that firms have increasingly shifted market risks onto their workforce to date there have been few detailed analyses exploring what factors have driven this phenomenon this study adds to our understanding of why firms have transferred risk to their employees by examining the decline of a highly institutionalized practice wherein large u s firms used to bear retirement risk the defined benefit db pension plan through a detailed analysis i show that variance in the presence power and interests of shareholders and employees at the firm level differentially affect a firm s willingness to shift the risk of retirement onto its workers specifically i demonstrate empirically that different types of shareholders have differential effects on a firm s retirement practices suggesting that the changing equity ownership structure of large u s firms has played a key role in how risk is allocated between workers and firms declines in employee power have also played a role because firm levels of unionization positively affect rates of db participation for both unionized and nonunionized workers

modelling sovereign credit spreads with international macro factors the case of brazil 1998 2009 abstract this paper develops a macro finance model of the brazilian economy and its sovereign debt markets that allows for domestic and international macroeconomic influences as well as swings in investor confidence it finds significant evidence of common trends in the us and brazilian economies and bond markets as well as spillover effects from us inflation and business cycles to the brazilian economy the us fed funds rate influences brazilian sovereign spreads as do brazilian inflation and policy rates the brazilian confidence factor dominates the behavior of the spreads during periods of crisis and we find that it also has a powerful effect on the level and volatility of macroeconomic variables these results suggest that the macro finance approach could throw light upon the behavior of other economies that are troubled by sovereign risk

liquidity and the dynamic pattern of asset price adjustment a global view abstract global liquidity expansion has been very dynamic since 2001 contrary to conventional wisdom high money growth rates have not coincided with a concurrent rise in goods prices at the same time however asset prices have increased sharply significantly outpacing the subdued development in consumer prices we investigate the interactions between money and goods and asset prices at the global level using aggregated data for major oecd countries our var results support the view that different price elasticities on asset and goods markets explain the observed relative price change between asset classes and consumer goods

the rise of the super rich power resources taxes financial markets and the dynamics of the top 1 percent 1949 to 2008 the income share of the super rich in the united states has grown rapidly since the early 1980s after a period of postwar stability what factors drove this change in this study we investigate the institutional policy and economic shifts that may explain rising income concentration we use single equation error correction models to estimate the long and short run effects of politics policy and economic factors on pretax top income shares between 1949 and 2008 we find that the rise of the super rich is the result of rightward shifts in congress the decline of labor unions lower tax rates on high incomes increased trade openness and asset bubbles in stock and real estate markets

government spending and the taylor principle this paper explores how government size affects the scope for equilibrium indeterminacy in a new keynesian economy where part of the population live hand to mouth the main result is that a higher level of public consumption is likely to generate indeterminacy and render the taylor principle insufficient as criterion for equilibrium uniqueness this holds even though fiscal policy serves to reduce swings in current income only if government consumption is a substitute for private consumption will it narrow the scope for indeterminacy hence monetary policy should be conducted with an eye to the amount and composition of government consumption

implied volatility functions empirical tests derman and kani 1994 dupire 1994 and rubinstein 1994 hypothesize that asset return volatility is a deterministic function of asset price and time and develop a deterministic volatility function dvf option valuation model that has the potential of fitting the observed cross section of option prices exactly using s p 500 options from june 1988 through december 1993 we examine the predictive and hedging performance of the dvf option valuation model and find it is no better than an ad hoc procedure that merely smooths black scholes 1973 implied volatilities across exercise prices and times to expiration

rule of thumb consumers productivity and hours in this paper we study the transmission mechanism of productivity shocks in a model with rule of thumb consumers in the literature this nancial friction has been studied only with reference to scal shocks we show that the presence of rule of thumb consumers is also very helpful in accounting for recent empirical evidence on productivity shocks rule of thumb agents together with nominal and real rigidities play an important role in reproducing the negative response of hours and the delayed responses of output and

nonunion wage rates and the threat of unionization i investigate how the threat of union organization affects the wage paid to nonunion workers i start by outlining the standard model of wage determination by a nonunion employer when faced with the threat of union organization the model suggests that the nonunion wage will be directly related and the union wage gap will be inversely related to the threat i use repeated cross section data from the cps from 1977 2002 to develop a measure of the threat as the predicted probability of union membership i use this measure to estimate earnings functions that use several sources of variation in the likelihood of union membership to identify the threat effect in a manner that reduces the likelihood of omitted variable bias finally i investigate two cases where there has arguably been a change in the likelihood of union organization that is not correlated with changes in the demand for labor these include the wage changes surrounding the introduction of rightto work rtw laws in two states during the period studied and wage changes surrounding deregulation of key industries in the late 1970s and early 1980s the results are mixed the preferred estimates from the analysis using predicted probability of unionization as the threat measure imply very little relationship between either nonunion wages or the union wage gap and the threat the estimates that rely on the introduction of rtw laws show a significant relationship between nonunion wages and the introduction of rtw laws in one of the two states stronger evidence of threat effects is found in the experience of deregulated industries where regulation was a central factor in union strength

union effects on nonunion wages evidence from panel data on industries and cities the authors test for threat and crowding effects of unions on non union wages at the industry and city levels using panel data on the percent organized and nonunion industry and city wage differentials constructed from current population surveys over the period 1973 89 at the industry level increases in the percent organized were associated with decreases in the nonunion industry wage differential suggesting that crowding effects were the predominant union effect on nonunion industry wage differentials in contrast at the city level increases in the percent organized were associated with increases in the nonunion city wage differential suggesting that threat effects predominated the authors also find evidence of negative cross occupation union effects on nonunion industry wage differentials supporting their hypothesis that the industry level results were partly driven by complementarity between union and nonunion labor

the politics of union decline the contingent determinants of union recognition elections and victories despite the close political regulation of union recognition disputes sociologists have paid little attention to recent political determinants of success in these contests a state centered political opportunity approach suggests that if conservative political officials can reduce the number of union recognition elections union organization will be blocked partly because many labor scholars claim there was a postwar departure in labor movement fortunes we attempt to detect and model a contingent break in the relationship between republican control of the presidency and these elections using interactive specifications our findings show that shortly after the conservative anti union reagan administration took office recognition elections and union victories in these elections fell sharply with macroeconomic and other determinants held constant other political conditions with explanatory power include congressional oversight committee ideology and conservative appointments to the key regulatory age

income inequality in the united states 1913 1998 this paper presents new homogeneous series on top shares of income and wages from 1913 to 1998 in the united states using individual tax returns data top income and wages shares display a u shaped pattern over the century our series suggest that the large shocks that capital owners experienced during the great depression and world war ii have had a permanent effect on top capital incomes we argue that steep progressive income and estate taxation may have prevented large fortunes from fully recovering from these shocks top wage shares were flat before world war ii dropped precipitously during the war and did not start to recover before the late 1960s but are now higher than before world war ii as a result the working rich have replaced the rentiers at the top of the income distribution

statistical tests of contingent claims asset pricing models abstract a new methodology for statistically testing contingent claims asset pricing models based on asymptotic statistical theory is proposed it is introduced in the context of the black scholes option pricing model for which some illustrative estimation inference and simulation results are also presented the proposed methodology is then extended to arbitrary contingent claims by first considering the estimation problem for general ito processes and then deriving the asymptotic distribution of a general contingent claim which depends upon such ito processes

unions and nonunion wage dispersion previous research has found that union standard rate policies lower the dispersion of union wages and that unions indirectly raise nonunion wage levels as firms weigh the probability of unionizing and wage costs these two findings imply that unions lower the dispersion of nonunion wages since for a given payroll a nonunion firm can achieve the greatest reduction in the probability of unionism by giving raises to those who would benefit most from a union this hypothesis is confirmed on current population survey data taking into account the endogeneity of unionism ceteris paribus nonunion wage dispersion is lower in more highly unionized industries copyright 1987 by mit press

simulation based estimation of contingent claims prices a new methodology is proposed to estimate theoretical prices of financial contingent claims whose values are dependent on some other underlying financial assets in the literature the preferred choice of estimator is usually maximum likelihood ml ml has strong asymptotic justification but is not necessarily the best method in finite samples this paper proposes a simulation based method when it is used in connection with ml it can improve the finite sample performance of the ml estimator while maintaining its good asymptotic properties the method is implemented and evaluated here in the black scholes option pricing model and in the vasicek bond and bond option pricing model it is especially favored when the bias in ml is large due to strong persistence in the data or strong nonlinearity in pricing functions monte carlo studies show that the proposed procedures achieve bias reductions over ml estimation in pricing contingent claims when ml is biased the bias reductions are sometimes accompanied by reductions in variance empirical applications to u s treasury bills highlight the differences between thebondpricesimpliedbythesimulation basedapproachandthosedeliveredbyml some consequences for the statistical testing of contingent claim pricing models are discussed jel c11 c15 g12

combining forecast densities from vars with uncertain instabilities recursive weight forecast combination is often found to an ineffective method of improving point forecast accuracy in the presence of uncertain instabilities we examine the effectiveness of this strategy for forecast densities using many vector autoregressive var and autoregressive ar models of output growth inflation and interest rates our proposed recursive weight density combination strategy based on the recursive logarithmic score of the forecast densities produces well calibrated predictive densities for us real time data by giving substantial weight to models that allow for structural breaks in contrast equal weight combinations produce poorly calibrated forecast densities for great moderation data copyright 2010 john wiley sons ltd

unions norms and the rise in u s wage inequality from 1973 to 2007 private sector union membership in the united states declined from 34 to 8 percent for men and from 16 to 6 percent for women during this period inequality in hourly wages increased by over 40 percent we report a decomposition relating rising inequality to the union wage distribution s shrinking weight we argue that unions helped institutionalize norms of equity reducing the dispersion of nonunion wages in highly unionized regions and industries accounting for unions effect on union and nonunion wages suggests that the decline of organized labor explains a fifth to a third of the growth in inequality an effect comparable to the growing stratification of wages by education

inflation targeting some extensions previous analyses of the implementation of inflation targeting are extended to monetary policy responses to different shocks consequences of model uncertainty and effects of interest rate smoothing and stabilization model uncertainty output stabilization and interest rate stabilization or smoothing all call for a more gradual adjustment of the conditional inflation forecast toward the inflation target the conditional inflation forecast is the natural intermediate target during inflation targeting the optimal way of reacting to shocks is hence to check how they affect the inflation forecast and then take the appropriate action jel classification e42 e52 e58

stochastic processes for interest rates and equilibrium bond prices default free bonds represent in essence money sold forward the investor gives dollars say to the government now in exchange for a contract which promises to pay with probability one a given number of dollars at maturity and possibly a stream of intermediate coupon payments prior to maturity only recently have financial economists begun to examine the pricing of those bonds in a portfolio context in that framework nominal liquidity premiums or risk premiums on long term default free bonds are attributable to uncertainty about taste technological and price level changes which may occur prior to maturity of the bonds and prior to each coupon payment if any to the extent that the investor is unable to diversify away that uncertainty there is a systematic risk attached to the marginal utility which he or she can derive from the use in consumption or investment of the dollar payoffs on the bonds in some term structure models the instantaneous or short term rate of interest denoted here as a function of time t by r t in nominal terms and r t in real terms can be taken as a sufficient statistic1 for the source of systematic uncertainty about the marginal utility of the proceeds to be derived from defaultfree bonds maturing beyond the next instant e g merton 1974 vasicek 1977 cox ingersoll and ross 1977 specific assumptions about tastes technology and utility functions lead to specific equilibrium stochastic processes for the instantaneous short term riskless rate and longer term bond prices which are modelled as functionally dependent upon maturity and that short term riskless rate if a closed form solution exists for the long term bond price as a function of maturity and the short term interest rate it will be conditional inter alia on the parameters of the stochastic process for that short term rate marsh 1981 proposed that the closed form solutions could be tested in terms of the restrictions implied cross sectionally on the parameters of the time series process for the returns or prices of longer term bonds each with a given term to maturity for an analogy outside the term structure literature think of the closed form solution given by black and scholes 1972 for the price of an option on a nondividend paying stock with lognormal price dynamics given the model the cross section of time series for the changes in prices for each of the several options written on the same stock are not unrestricted their dispersion is functionally linked to the same volatility parameter for the stock price thus the option model including

this job is getting old measuring changes in job opportunities using occupational age structure high and low wage occupations are expanding rapidly relative to middle wage occupations in both the u s and the e u we study the reallocation of workers from middle skill occupations towards the tails of the occupational skill distribution by analyzing changes in age structure within and across occupations because occupations typically expand by hiring young workers and contract by curtailing such hiring we posit that growing occupations will get younger while shrinking occupations will get old after verifying this proposition we apply this observation to local labor markets in the u s to test whether markets that were specialized in middle skilled occupations in 1980 saw a differential movement of both older and younger workers into occupations at the tails of the skill distribution over the subsequent 25 years consistent with aggregate trends employment in initially middle skill intensive labor markets hollowed out between 1980 and 2005 employment losses among non college workers in the middle of the occupational skill distribution were almost entirely countered by employment growth in lower tail occupations for college workers employment losses at the middle were offset in roughly equal measures by gains in the upper and lower tails of the occupational skill distribution but gains at the upper tail were almost entirely limited to young college workers consequently older college workers are increasingly found in lower skill lower paying occupations this abstract was borrowed from another version of this item

forecasting the fragility of the banking and insurance sectors linkages between banks and insurance companies are important when forecasting the fragility of the banking and insurance sectors we propose a novel empirical framework that allows us to estimate unobserved linkages in panel data sets that contain observed regressors we find that taking unobserved common factors into account reduces the root mean square forecasts error of firm specific forecasts by up to 9 of system forecasts by up to 14 and by up to 39 for systemic forecasts of more distressed firms relative to a model based on observed variables only estimates of the factor loadings suggest that the correlation of financial institutions has been relatively stable over the forecast period

the effect of unions on wage inequality in the u s labor market this study uses current population survey micro data for 1973 74 and 1993 to evaluate the effect of changing union membership on trends in male and female wage inequality unionization rates of men fell between the two sample periods with bigger declines among lower skill groups these trends account for 15 20 of the rise in male wage inequality union membership rates of low wage women also declined while unionization increased among higher wage women on balance shifting unionization accounts for very little of the rise in female wage inequality economy wide trends in unionization mask a sharp divergence between the private sector where unionism was declining and the public sector where it was rising comparisons across sectors suggest that unionization substantially slowed the growth in wage inequality in the public sector

are jumps in stock returns diversifiable evidence and implications for option pricing this paper studies the diversiflability of jumps in stock returns it presents a multivariate time series model of the stochastic process for an index and its component stocks that explicitly admits discrete common jumps maximum likelihood estimation for such a model is developed and applied to the daily major market index and its component stocks for the period 1985 through 1990 the paper finds that poisson distributed jumps observed from both the index and its component stocks constitute nondiversiflable risk implying that the standard assumption in option pricing that these jumps are not priced may be invalid

costs of banking system instability some empirical evidence abstract this paper assesses the cross country stylised facts on empirical measures of the losses incurred during periods of banking crises we first consider the direct resolution costs to the government and then the broader costs to the welfare of the economy proxied by losses in gdp we find that the cumulative output losses incurred during crisis periods are large roughly 15 20 on average of annual gdp in contrast to previous research we also find that output losses incurred during crises in developed countries are as high or higher on average than those in emerging market economies moreover output losses during crisis periods in developed countries also appear to be significantly larger 10 15 than in neighbouring countries that did not at the time experience severe banking problems in emerging market economies by contrast banking crises appear to be costly only when accompanied by a currency crisis these results seem robust to allowing for macroeconomic conditions at the outset of crisis in particular low and declining output growth that have also contributed to future output losses during crises episodes

excess liquidity bank pricing rules and monetary policy abstract this paper studies the implications of excess bank liquidity for the effectiveness of monetary policy in a simple model with credit market imperfections the demand for excess reserves is determined by precautionary factors and the opportunity cost of holding cash it is argued that excess liquidity may impart greater stickiness to the deposit rate in response to a monetary contraction and induce an easing of collateral requirements on borrowers which in turn may translate into a lower risk premium and lower lending rates as a result asymmetric bank pricing behavior under excess liquidity may hamper the ability of a contractionary monetary policy to lower inflation

on the estimation of union threat effects some researchers view unions primarily as functioning to increase earnings inequality among the working class while others see them as threatening employers so that they raise wages for unorganized workers and minimize working class inequality threat effects are defined as the tendency for nonunionized employers to respond to the threat of unionization by increasing the earnings and benefits of their workers this paper probes a contextual method for estimating the effects of unionization on the earnings of unorganized workers this method controls for structural characteristics that affect workers earnings and incorporates information about the organizational strength and vitality of specific unions using data from seven manufacturing industries in indianapolis the results suggest that 1 unionized workers earnings positively affect the earnings of unorganized workers in unionized plants 2 unionized workers earnings negatively affect nonunionized workers earnings in nonunionized plants and 3 when plant size is controlled unionized workers earnings have no significant effect on the earnings of nonunionized workers in nonunionized plants these results highlight the complexity and difficulty of estimating the effects of union threat and their importance for understanding earnings inequality in the workplace

flexible inflation targeting and financial stability is it enough to stabilize inflation and output abstract we investigate empirically whether a central bank can promote financial stability by stabilizing inflation and output and whether additional stabilization of asset prices and credit growth would enhance financial stability in particular we employ an econometric model of the norwegian economy to investigate the performance of simple interest rate rules that allow a response to asset prices and credit growth in addition to inflation and output we find that output stabilization tends to improve financial stability additional stabilization of house prices equity prices and or credit growth enhances stability in both inflation and output but has mixed effects on financial stability in general financial stability as measured by e g asset price volatility improves while financial stability measured by indicators that depend directly on interest rates deteriorates mainly because of higher interest rate volatility owing to a more active monetary policy

occupations and the structure of wage inequality in the united states 1980s to 2000s occupations are central to the stratification systems of industrial countries but they have played little role in empirical attempts to explain the well documented increase in wage inequality that occurred in the united states in the 1980s and 1990s we address this deficiency by assessing occupation level effects on wage inequality using data from the current population survey for 1983 through 2008 we model the mean and variance of wages for each occupation controlling for education and demographic factors at the individual level to test three competing explanations for the increase in wage inequality 1 the growth of between occupation polarization 2 changes in education and labor force composition and 3 residual inequality unaccounted for by occupations and demographic characteristics after correcting for a problem with imputed data that biased kim and sakamoto s 2008 results we find that between occupation changes explain 66 percent of the increase in wage inequality from 1992 to 2008

does the law of one price hold in international financial markets evidence from tick data abstract this paper investigates the validity of the law of one price lop in international financial markets by examining the frequency size and duration of inter market price differentials for borrowing and lending services one way arbitrage using a unique data set for three major capital and foreign exchange markets that covers a period of more than seven months at tick frequency we find that the lop holds on average but numerous economically significant violations of the lop arise the duration of these violations is high enough to make it worthwhile searching for one way arbitrage opportunities in order to minimize borrowing costs and or maximize earnings on given funds we also document that such opportunities decline with the pace of the market and increase with market volatility

sluggish institutions in a dynamic world can unions and industrial competition coexist during the 1930s and 1940s collective bargaining emerged as the workplace governance norm in much of the u s industrial sector following its peak in the 1950s union density in the u s private sector fell steadily to only 7 4 percent in 2006 governance shifted from a formalized union norm to one of constrained managerial discretion in competitive and dynamic economic environments a union tax on company earnings and slow response to economic shocks combine to produce poor performance by union companies two industries automotives and airlines are used to illustrate these points if worker based institutions are to flourish they must add value and permit companies to perform at levels similar to those obtained under evolving nonunion governance norms

targeting nominal income an appraisal the practice of setting target growth rates for a year or more ahead for some measure of the mofiey supply is now followed by many industrialised countries however it has been suggested by a number of authors e g meade i978 in his nobel prize lecture tobin i980 in his retrospective on stabilisation policy brittan i98i that it would be more sensible to pursue targets for nominal income rather than the money supply meade for instance argues that controlling nominal income is in any case the ultimate goal of those who favour fixed monetary targets and that an excessive concentration on the means rather than the end is confusing to private agents and can lead to undesirable fluctuations in the demand for output when velocity shifts he goes on to advocate that nominal income targets should be linked to the development of wage fixing institutions designed to mimic competitive behaviour in this paper we examine the implications of such a proposal for the performance of the economy in the context of a simple stochastic macroeconomic model under rational expectations a contracting framework is adopted in which the wage is fixed in a state of uncertainty about future levels of demand and productivity the objective of the authorities is to minimise the divergence of output from its full information equilibrium level if labour supply is inelastic then it turns out that maintaining the level of nominal income is actually the optimal policy if labour supply is elastic nominal income targetry provides an optimal response to demand is lm shocks but a suboptimal response to productivity shocks however a sufficient condition for a nominal income target to be preferable to a fixed money supply target is that the price elasticity of aggregate demand be less than unity the paper concludes by examining the implications of pursuing target growth rates rather than levels it should be conceded at the outset that there are several pertinent issues not addressed such as the greater comprehensibility of nominal income targets to private agents or the possibility that nominal income targets may leave the authorities with too much discretion e g poole i980 the issue of labour market reform is also ignored this is an enormous subject which it would be impossible to do justice to here see for instance meade s own analysis of the problem in meade i982 such reforms might be expected to affect the parameters of the model nevertheless since changes in labour market practices are neither a precondition for nor a logical consequence of nominal income targets an independent analysis of the macrceconomic implications of the latter is still highly relevant

transactions data tests of efficiency of the chicago board options exchange abstract this paper performs lower boundary condition tests based on rational pricing of call options and an implied standard deviation test based on the bid ask prices of options these efficiency tests attempt to closely approximate conditions in the option markets to avoid the pitfalls indicated by phillips and smith 1980 the tests use transactions data and account for the effects of stock and option bid ask prices simultaneity of stock and option prices depth of market execution lag and transaction costs the small and relatively infrequent profits due to market mispricing disappear in the lower boundary tests when transaction costs are taken into account frequent violations of the tighter boundary conditions in the implied standard deviation test are reported but the estimated profits cannot be unambiguously attributed to option market inefficiency

performance pay and wage inequality an increasing fraction of jobs in the u s labor market explicitly pay workers for their performance using bonus pay commissions or piece rate contracts using data from the panel study of income dynamics we show that compensation in performance pay jobs is more closely tied to both observed and unobserved productive characteristics of workers than compensation in non performance pay jobs we also find that the return to these productive characteristics increased faster over time in performance pay than in non performance pay jobs we show that this finding is consistent with the view that underlying changes in returns to skill due for instance to technological change induce more firms to offer performance pay contracts and result in more wage inequality among workers who are paid for performance thus performance pay provides a channel through which underlying changes in returns to skill get translated into higher wage inequality we conclude that this channel accounts for 21 of the growth in the variance of male wages between the late 1970s and the early 1990s and for most of the increase in wage inequality above the eightieth percentile over the same period

skill biased technological change and wage inequality evidence from a plant retooling1 one of the most popular explanations for the increased wage inequality that has occurred since the late 1970s is that technological change has resulted in a downward shift in the demand for low skill workers this pattern is also alleged to account for the growth in racial inequality in wages over the same period this article reports on a case study of the retooling of a food processing plant a unique longitudinal multimethod design reveals the nature of the technological change the changes in job requirements and the mechanisms by which the changes affect the wage distribution for hourly production workers this research finds that indeed the retooling resulted in greater wage dispersion and that the changes have also been associated with greater racial inequality in wages however contrary to the claims of advocates of the skill bias hypothesis organizational and human resources factors strongly mediated the impact of the changing technology absent these high road organizational choices th

life cycle patterns of interest rate markups in small firm finance we derive empirical implications from a theoretical model of bank borrower relationships the interest rate mark ups of banks are predicted to follow a life cycle pattern over the age of the borrowing firms because of endogenous bank monitoring by competing banks borrowing firms initially face a low mark up and thereafter an increasing mark up as a result of informational lock in until it falls for older firms when the lock in is resolved by applying a large sample of predominantly small unlisted firms and a new measure of asymmetric information we find that firms with significant asymmetric information problems have a more pronounced life cycle pattern of interest rate mark ups additionally we examine the effects of concentrated banking markets on interest rate mark ups the results indicate that the life cycle of mark ups is mainly driven by asymmetric information problems and not by concentration however we find evidence that bank market concentration matters for older firms

the american jobs crisis and its implication for the future of employment policy a call for a new jobs compact the author proposes a new jobs compact to close the nation s jobs deficit to create sufficient high quality jobs to raise wages and end thirty years of wage stagnation and to update and strengthen labor and employment policies a set of market and institutional failures are identified as root causes of these problems and local innovations and policy proposals are suggested for overcoming them achieving these objectives will require a stronger voice in national policymaking as well as proactive efforts to mobilize and coordinate the constituencies that share an interest in and responsibility for employment policy and practice the author calls on the president and the secretary of labor to lead these efforts by mobilizing and engaging business labor women ethnic community and education leaders at regional and national levels

distributional national accounts methods and estimates for the united states this article combines tax survey and national accounts data to estimate the distribution of national income in the united states since 1913 our distributional national accounts capture 100 of national income allowing us to compute growth rates for each quantile of the income distribution consistent with macroeconomic growth we estimate the distribution of both pretax and posttax income making it possible to provide a comprehensive view of how government redistribution affects inequality average pretax real national income per adult has increased 60 from 1980 to 2014 but we find that it has stagnated for the bottom 50 of the distribution at about 16 000 a year the pretax income of the middle class adults between the median and the 90th percentile has grown 40 since 1980 faster than what tax and survey data suggest due in particular to the rise of tax exempt fringe benefits income has boomed at the top the upsurge of top incomes was first a labor income phenomenon but has mostly been a capital income phenomenon since 2000 the government has offset only a small fraction of the increase in inequality the reduction of the gender gap in earnings has mitigated the increase in inequality among adults but the share of women falls steeply as one moves up the labor income distribution and is only 11 in the top 0 1 in 2014

through the contested terrain implementation of downsizing announcements by large u s firms 1984 to 2005 since the 1980s leading u s firms have announced massive downsizing plans in the name of maximizing shareholder value but some observers are skeptical about how serious firms are in implementing

what can we learn from the implementation of monetary and macroprudential policies a systematic literature review the emergence of macroprudential policies implemented by central banks as a means of promoting financial stability has raised many questions regarding the interaction between monetary and macroprudential policies given the limited number of studies available this paper sheds light on this issue by providing a critical and systematic review of the literature to this end we divide the theoretical and empirical studies into two broad channels of borrowers consisting of the cost of funds and the collateral constraint and financial intermediaries consisting of risk taking and payment systems in spite of the existing ambiguity surrounding coordination issues between monetary and macroprudential policies it is argued that monetary policy alone is not sufficient to maintain macroeconomic and financial stability hence macroprudential policies are needed to supplement monetary in addition we find that the role of the exchange rate is critical in the implementation of monetary and macroprudential policies in emerging markets while volatile capital flows pose another challenge in so far as how the arrangement of monetary and macroprudential policies varies across countries key theoretical and policy implications have been identified

match bias in wage gap estimates due to earnings imputation about 30 of workers in the current population survey have earnings imputed wage gap estimates are biased toward zero when the attribute being studied e g union status is not a criterion used to match donors to nonrespondents an expression for match bias is derived in which attenuation equals the sum of match error rates attenuation can be approximated by the proportion with imputed earnings union wage gap estimates with match bias removed are presented for 1973 2001 estimates for recent years are biased downward 5 percentage points bias in gap estimates accompanying other non match criteria public sector industry etc is examined

assessing the lucas critique in monetary policy models empirical estimates of monetary policy rules suggest that the behavior of u s monetary policymakers changed during the past few decades however for that same time period statistical analyses of lagged representations of the economy such as vars often have not rejected the null of structural stability these two sets of empirical results appear to contradict the lucas critique this paper reconciles these results with the lucas critique by showing that the apparent policy invariance of reduced forms is consistent with the magnitude of historical policy shifts and the relative insensitivity of the reduced forms of plausible forward looking macroeconomic specifications to policy shifts

growing apart the changing firm size wage premium and its inequality consequences wage inequality in the united states has risen dramatically over the past few decades prompting scholars to develop a number of theoretical accounts for the upward trend this study argues that large firms have been a prominent labor market institution that mitigates inequality by compensating their low and middle wage employees with a greater premium than their higher wage counterparts large u s firms reduced overall wage dispersion yet broader changes to employment relations associated with the demise of internal labor markets and the emergence of alternative employment arrangements have undermined large firms role as an equalizing institution using data from the current population survey and the survey of income and program participation we find that in 1989 although all private sector workers benefited from a firm size wage premium the premium was significantly higher for individuals at the lower end and middle of the wage distribution compared to those at the higher end between 1989 and

immigration and inequality immigration is often viewed as a proximate cause of the rising wage gap between highand low skilled workers nevertheless there is controversy over the appropriate theoretical and empirical framework for measuring the presumed effect and over the precise magnitudes involved this paper offers an overview and synthesis of existing knowledge on the relationship between immigration and inequality focusing on evidence from cross city comparisons in the u s while some researchers have claimed that a cross city research design is inherently flawed i argue that the evidence from cross city comparisons is remarkably consistent with recent findings based on aggregate time series data in particular cross city and aggregate time series comparisons provide support for three key conclusions 1 workers with below high school education are perfect substitutes for those with a high school education 2 high school equivalent and college equivalent workers are imperfect substitutes with an elasticity of substitution on the order of 2 3 within education groups immigrants and natives are imperfect substitutes together these results imply that the average impacts of recent immigrant inflows on the relative wages of u s natives are small the effects on overall wage inequality including natives and immigrants are larger reflecting the concentration of immigrants in the tails of the skill distribution and higher residual inequality among immigrants than natives even so immigration accounts for a small share 5 of the increase in u s wage inequality between 1980 and 2000

valuation of american call options on dividend paying stocks empirical tests abstract this paper examines the pricing performance of the valuation equation for american call options on stocks with known dividends and compares it with two suggested approximation methods the approximation obtained by substituting the stock price net of the present value of the escrowed dividends into the black scholes model is shown to induce spurious correlation between prediction error and 1 the standard deviation of stock return 2 the degree to which the option is in the money or out of the money 3 the probability of early exercise 4 the time to expiration of the option and 5 the dividend yield of the stock a new method of examining option market efficiency is developed and tested

workplace compensation practices and the rise in benefit inequality this article aims to explain why inequality in fringe benefits has grown faster than wage inequality over the past four decades we depart from previous income inequality research by studying benef
