aspects of labor market adjustments in japan this article discusses some aspects of labor market adjustments in japan that may be relevant to the low unemployment rate there japanese statistics treat kyugyosha persons not at work as being employed but some of these workers would be counted as unemployed in the united states the kyugyosha group appears to increase in size during downturns and decreases during upturns suggesting that temporarily laid off persons are an important part of this group japanese employers evidently rely less on employment adjustments and more on adjustments in hours of work and inventory while employers in the united states rely more on employment adjustments to deal with cyclical changes in product demand japanese manufacturing employment became less sensitive and hours of work more sensitive to demand shocks after the introduction of the employment insurance law in 1975

correlation neglect voting behavior and information aggregation in this paper we analyse elections when voters underestimate the correlation between their information sources correlation neglect we find that this cognitive bias can improve political outcomes we show that the extreme beliefs which result from correlation neglect induce some voters to base their vote on information rather than on political preferences we characterise conditions on the distribution of preferences under which this induces higher vote shares for the optimal policies and better information aggregation

ownership consolidation and product characteristics a study of the us daily newspaper market this paper develops a structural model of newspaper markets to analyze the effects of ownership consolidation taking into account not only firms price adjustments but also the adjustments in newspaper characteristics a new dataset on newspaper prices and characteristics is used to estimate the model the paper then simulates the effect of a merger in the minneapolis newspaper market and studies how welfare effects of mergers vary with market characteristics it finds that ignoring adjustments of product characteristics causes substantial differences in estimated effects of mergers jel g32 l13 l82 m37 do mergers affect product characteristics standard merger analyses typically study price effects only and ignore changes in product characteristics this paper endogenizes both it is likely that firms would adjust the features of their products after a merger ignoring this aspect of firm decisions in a merger analysis can lead to a bias in estimated welfare effects specifically i study how ownership consolidation affects product characteristics and welfare in the us daily newspaper market the newspaper market provides an ideal environment for analyzing the effect of mergers on product features for both econometric and economic reasons first of all individual newspapers often circulate in local markets there is substantial variation in demographics and ownership structure across these markets this variation is crucial for this study secondly the characteristics of newspapers are obviously important for welfare for example after an ownership consolidation do newspaper publishers improve or diminish the content quality do they enlarge or shrink the local news ratio do they increase or decrease content variety to address these questions i set up a structural model of the us daily newspaper

markups aggregation and inventory adjustment in this paper i suggest a unified explanation for two puzzles in the inventory literature first estimates of inventory speeds of adjustment in aggregate data are very small relative to the apparent rapid reaction of stocks to unanticipated variations in sales second estimates of inventory speeds of adjustment in firm level data are significantly higher than in aggregate data the paper develops a multisector model where inventories are held to avoid stockouts and price markups vary along the business cycle the omission of countercyclical markup variations from inventory targets introduces a downward bias in estimates of adjustment speeds obtained from partial adjustment models when the cyclicality of markups differs across sectors this downward bias is shown to be more severe with aggregate rather than firm level data similar results apply not only to inventories but also to labor and prices montercarlo simulations of a calibrated version of the model suggest that these biases are quantitatively significant

corporate financial policy and corporate control abstract this paper presents evidence that stockholder wealth declines on average when managers respond to attempted hostile takeovers with defensive changes in asset and ownership structure the data also indicate that these corporate restructurings are typically quite large and that many are attempts by managers to create barriers specific to the hostile bidder and or to consolidate a block of voting securities in the hands of management allies the evidence suggests that defensive motives whether beneficial or harmful influence corporate asset and ownership structure

political agency government responsiveness and the role of the media abstract the role of mass media in making governments responsive to the needs of citizens is a relatively neglected area in economics we sketch a theoretical example with a role for media in enhancing government responsiveness based on asymmetric information between citizens and government we then use data for the period 1958 1992 on the extent to which indian state governments responded to food shortages via the public distribution of food correlating these with proxies of media political and economic development we find that states that are more responsive tend to also be those with high levels of newspaper circulation electoral turnout and literacy in contrast richer states do not tend to be more responsive than poorer states

buffer stocks and labor demand further evidence this paper presents estimates of a multivariate flexible accelerator model of labor demand hours and the number of production workers which shows that stocks of finished goods unfilled orders and materials inventories have significant impacts upon labor demand univariate time series models are used to capture expectations of the determinants of desired stocks new orders real wages and real raw materials prices and these magnitudes are found to follow a random walk without drift expected new orders and errors in forecasting new orders are found to have an important impact upon labor inputs real wage forecasting errors are found to be important for hours demand

why u s wage and employment behavior differs from that in britain and japan if a poll were to be conducted among american academic economists to select the most mystifying economic phenomenon of our time surely the sticky nominal wage rate would emerge at or near the top of the list the slow and partial response of the nominal wage rate to changes in aggregate nominal spending has been a central postulate of macroeconomic theory for the past 45 years from keynes general theory down to the standard postwar textbook keynesian paradigm to the more modern fixed wage price models of robert barro and herschel grossman i976 and edmond malinvaud i977 unwilling passively to accept nominal wage rigidity as an unexplained assumption many labour market theorists have followed the lead of costas azariadis i975 and martin baily i974 in building models to explain rigid wages and layoff unemployment as the rational outcome of a profit maximising calculus as i pointed out in an early critique of the azariadis baily model i976a their assumptions cannot explain cycles in employment but rather why workers would want fixed incomes i e a fixed wage rate and fixed employment soon thereafter barro i977 went one step further and argued that contract theory is a facade which cannot explain why workers would choose a rigid wage and variable employment in preference to the classical equilibrium quantity of employment that equates the marginal product of labour with the marginal value of time now an examination of the evidence has led me to the realisation that rigid wages cannot provide the underpinnings for a universally valid theory of the business cycle simply because wages are not universally rigid i document below with postwar quarterly data that the share of fluctuations in the manufacturing wage bill taking the form of nominal wage changes as compared to changes in hours worked is five to ten times greater in britain and japan than in

cyclical productivity in europe and the united states evaluating the evidence on returns to scale and input utilization this paper studies procyclical productivity growth at the industry level in the united states and three european countries france germany and the netherlands industry specific demand side instruments are used to examine the prevalence of non constant returns to scale and unmeasured input utilization for the aggregate us economy unmeasured input utilization seems to explain procyclical productivity however this correction still leaves one in three us industries with procyclical productivity this failure of the model can also be seen in europe and is mostly concentrated in services industries

unionism mio the cyclical behavior of the labor tv rket in u s manufacturing t he traditional view of market dynamics implies that when demand varies intertemporal variation in quantities exchanged increases as prices become less flexible this reasoning leads to the proposition that wage and price rigidities are important contributors to cyclical fluctuations in output fischer 1977a and gray 1978 based formal macro models on this principle although this view is common it has little empirical support the coexistence of union and nonunion establishments engaged in similar activities contains potential for testing its merits economists have long maintained that in the short run union wages are less flexible than nonunion wages dunlop 1950 rees 1951 this difference should produce larger fluctuations in union employment and hours empirical studies have generally supported the union wage rigidity hypothesis lewis 1963 ashenfelter johnson and pencavel 1972 and hendricks 1981 2 but until recently lack of data precluded analysis of hours and employment definitive answers to the important questions concerning unions influence on cyclical behavior require yet unavailable information matching the behavior of firms and characteristics of workers but data from modem surveys have allowed considerable progress nevertheless it remains a challenge to determine how much of differences observed in the stability of labor utilization are attributable to differences in the stability of demand medoff 1979 and raisian 1979 report that cyclical variation of employment and hours is indeed greater for union labor but despite attempts to allay suspicion that their finding arises primarily from concentration of union members in cyclically sensitive industries both studies leave room for doubt raisian estimated functions relating an individual s wage and weeks worked in a year to a proxy for excess demand that year s unemployment rate in the worker s industry the technique is attractive but raisian s data included workers from the entire economy and the industries were broad aggregates thus differences in the union and nonunion groups compositions may play a large role medoff who confined his study to production workers in manufacturing and used data allowing finer partitions investigated the importance of composition more thoroughly but he did not estimate relationships between adjustments in employment or hours and a measure of demand furthermore his focus was principally on the composition of manhours adjustments rather than their size in this paper i combine the strongest features of the medoff and raisian studies in further examination of the influence of unionism on cyclical fluctuations using current population surveys u s department of commerce 1978 from may of 1973 75 my analysis covers production workers in manufacturing during a period of rising inflation and unemployment the heart of the analysis is a measure of residual employment that quantifies by three digit industry and year shortrun excess demand for labor i construct this variable from employment time series and use it to estimate union nonunion differences in the cyclical responses of unemployment hourly wage rates and hours worked the results are consistent with the view that increasing rigidity in wages amplifies cyclical fluctuations in the utilization of labor the wage regressions add further to the literature s already strong support for the union wage rigidity hypothesis the employment status and hours regressions imply that the sensitivities of employment received for publication august 12 1981 revision accepted for publication february 11 1983 federal reserve bank of dallas this paper is based on my ph d dissertation which was completed at ucla with financial assistance from the rand corporation and the department of labor comments by referees and by participants of labor workshops at ucla and the university of chicago as well as the computation assistance of brian mckee are gratefully acknowledged i am responsible for any remaining errors the views expressed should not be attributed to the federal reserve bank of dallas or the federal reserve system one study is gordon 1982 who concludes page 41 that macroeconomic instability in the united states has been aggravated by the unusually sluggish behavior of nominal wages in the postwar era 2see also johnson 1975 parsley 1980 and moore and raisian 1980

determination of employment with wage and price speculation the purpose of this paper is to investigate whether aggregate fluctuations in employment may be explained within a market clearing framework as intertemporal substitution in labor supply and demand an intertemporal substitution model for the firm is derived this model is estimated with a lucas rapping type supply equation empirical results with finnish data lend support to the intertemporal substitution model particularly concerning the demand function specification on the other hand the results for the supply equation are somewhat mixed being rather sensitive to the dynamic specification

competition and truth in the market for news in this essay we evaluate the case for competition in news markets from the perspective of economics first we consider the simple proposition that when more points of view are heard and defended beliefs will converge to the truth this concept of competition is several steps removed from market competition among actual media firms but it has played a prominent role in the legal arguments for a free press we then explore three mechanisms by which increasing competition or more precisely increasing the number of independently owned firms can limit bias or distortions that originate on the supply side of the media market first when governments attempt to manipulate news competition can increase the likelihood that the media remain independent second when news providers have an interest in manipulating consumers beliefs diversity in such incentives can reduce the risk of information being suppressed or distorted third competition may drive firms to invest in providing timely and accurate coverage overall we argue that there are robust reasons to expect competition to be effective in disciplining supply side bias next we ask how the effect of competition changes when distortions originate on the demand side of the market when consumers themselves demand biased or less socially relevant news we find that increased competition may or may not improve welfare in these cases though we caution against using this as a justification for concentrating media power in the hands of state controlled or regulated firms

external effects in u s procyclical productivity abstract in this paper we highlight a new dimension of the aggregate procyclical productivity phenomenon we show that estimates of the degree of returns to scale are larger for manufacturing as a whole than for two digit industries since this difference must be due to factors that are only internalized at the most aggregate level we term it an external effect this result rules out explanations based on own input variation such as true increasing returns and unmeasured factor utilization tied to own activity as the sole explanations for aggregate procyclical productivity we explore several potential explanations of this external effect

agency conflicts in public and negotiated transfers of corporate control we analyze control transfers in firms with a dominant minority blockholder and otherwise dispersed owners and show that the transaction mode is important negotiated block trades preserve a low level of ownership concentration inducing more inefficient extraction of private benefits in contrast public acquisitions increase ownership concentration resulting in fewer private benefits and higher firm value within our model the incumbent and new controlling party prefer to trade the block because of the dispersed shareholders free riding behavior we also explore the regulatory implications of this agency problem and its impact on the terms of block trades

mass media and public policy abstract if more informed voters receive favorable policies then mass media should influence policy because it provides most of the information people use in voting this paper uses a simple model to analyze the effect of mass media provision of news on a number of policy issues redistribution the size of the government sector rents and corruption the effectiveness of lobby groups and political business cycles it is easy to deal with such a wide range of issues because existing models of political competition often include informed and uniformed voters modelling mass media simply endogenizes who is informed and who is not the paper also discusses empirical evidence and point to areas for future research

optimal toeholds in takeover contests abstract we offer an explanation for why raiders do not acquire the maximum possible toehold prior to announcing a takeover bid by endogenously modeling the target firm s value following an unsuccessful takeover we demonstrate that a raider may optimally acquire a small toehold even if the acquisition does not drive up the pre tender target price this occurs because although a larger toehold increases profits if the takeover succeeds it also conveys a higher level of managerial entrenchment and hence a lower firm value if the takeover fails we derive new predictions regarding the optimal toehold and target value following a failed takeover we also examine the impact of a rival bidder and dilution

exposing corrupt politicians the effects of brazil s publicly released audits on electoral outcomes author s finan frederico ferraz claudio abstract this paper examines the extent to which access to information enhances political accountability based upon the results of brazil s recent anti corruption program that randomly audits municipal expenditures of federally transferred funds it estimates the effect of the disclosure of local government corruption practices upon the re election success of incumbent mayors in municipal elections comparing municipalities which were randomly audited before the elections with those audited after the analysis shows that the disclosure of audit results had a significant impact on the re election rates of mayors found to be corrupt for a one standard deviation increase in reported corruption the audit policy reduced the incumbent s likelihood of re election by 25 percent this effect is more pronounced in municipalities where radio stations are present and higher levels of corruption are identified these findings highlight the value of information and the role of the media in reducing informational asymmetries in the political process thus enabling voters to not only hold corrupt politicians accountable but also to reward non corrupt politicians

production smoothing in the japanese vehicle industry abstract physical data from the japanese vehicle industry covering monthly observations from 1985 1 to 1994 12 are investigated across nine goods ranging from bicycles to large buses smaller variance of production is found relative to sales across all goods for unadjusted data and in 17 out of 18 cases for seasonally adjusted data such evidence in favor of the production smoothing model psm is confirmed by full information maximum likelihood employed jointly on inventories and sales equations the estimates suggest the industry operates in the range of increasing marginal costs in six out of nine goods positive costs of being away from targeted inventory are also present in six out of these nine goods which make the psm a good description of this industry

some empirical estimates of the demand for hours in u s manufacturing industries this paper presents estimates of hours equations based upon optimizing behavior of firms in a dynamic context the order stock distinction is the point of departure for this paper firms will be presumed here to produce to stock or to order hours equations will be derived which link hours worked to levels of inventories of finished goods or unfilled orders early work on the demand for labor ignored the effects of inventones and unfilled orders on the choice of labor input levels however some evidence on this subject was provided by the important and well known work of nadiri and rosen 1973 1 using a theoretical framework first studied by lucas 1967 they estimate dynamic factor demand schedules for six quasi fixed factors of production i e factor inputs which are subject to adjustment costs among these six inputs are employment hours per man and total inventories it is well known that the accumulation of any input will then depend upon the gaps between desired and actual levels of all quasi fixed factors thus the demand for hours per man is taken to depend among other things upon lagged hours employment and total inventories the cyclical interaction between inventories and the demand for labor arises through adjustment parameters attached to these lagged stocks completing the specification of the model by including the determinants of desired stocks sales the wage relative to capital costs and a time trend they apply the model to industrial aggregate data their results provide little evidence that inventories are an important determinant of the demand for hours of the eighteen industries examined only six produce negative and significant inventory coefficients further relative factor prices are found to be significant in only six industries apart from aggregation bias issues there are several misspecifications which could account for these results there is no reason why the impact of each inventory stock should have an identical impact upon hours for example it is reasonable to suppose that if the firm holds excess finished goods relative to desired levels it will reduce hours per worker but if the firm holds stocks of materials which exceed desired levels the firm may wish to increase hours so as to offset the output effects through the production function of declining stocks of materials similar comments can be offered about work in process inventories thus disaggregating by stage of fabrication would appear to be appropriate to sort out inventory effects on hours demand second nadiri and rosen ignore the impact of order backlogs upon hours following belsley 1969 it is well known that many of the firms in these industries produce not to stock but to order for firms producing goods requiring special attention order backlogs replace finished goods as a buffer against fluctuations in demand thus order backlogs should appear directly in the hours equation finally the dynamics of labor demand and factor prices may require a distributed lag representation to capture the response of labor demand to shifts in expected real wages as suggested by neftci 1978 in a different context the effects of real wages on hours may be captured if allowance is made for a distributed lag relationship between hours and real wages this paper presents two models which are designed to address some of these issues extending received for publication june 30 1982 revision accepted for publication january 7 1983 pennsylvania state university the research reported in this paper was partially supported by the employment and training administration u s department of labor under research and development grant no 91 24 77 34 and by the federal reserve bank of philadelphia the views expressed herein are those of the author and do not necessarily reflect those of the sponsoring institutions or the federal reserve system in any way i wish to thank professors c f christ l j maccini h rose and m ali khan for their constructive criticisms of this research two anonymous referees also provided excellent comments john hinrichs of the bureau of economic analysis kindly provided the deflated inventory data used here diane mayer and donna robinson provided expert research assistance any remaining errors are the responsibility of the author l see nadiri and rosen 1973 for a survey of the employment demand literature

procyclical labour productivity increasing returns to labour and labour hoarding in car assembly plant employment this paper empirically examines the sources of procyclicality in labor productivity for a panel of u s auto assembly plants from 1978 85 an employment demand equation derived from a cost minimization model is estimated to test for the presence of increasing returns and labor hoarding on the employment dimension the data used match employment and wage data from the bls current establishment survey to publically available data on output and the nature of production at these plants statistical evidence in favor of both increasing returns and hoarding is found these findings suggest that the observed procyclicality of labor productivity in this industry is due to both the nature of technology increasing returns as well as attempts by plant managers to maintain a reserve of experienced workers labor hoarding copyright 1992 by royal economic society

corruption via media capture the effect of competition in this article we compare a government s optimal choice of whether to engage in corruption by capturing the media outlets through bribery in two alternative media market structures monopoly versus duopoly while there is an extra bribe claimant in a media duopoly relative to monopoly it may also be harder for each firm to individually expose corruption when the rival co opts with the government we find that when the latter effect is stronger than the former media is captured at lower bribes under duopoly relative to monopoly and in such instances media competition facilitates rather than hindering corruption

takeover bids and the relative prices of shares that differ in their voting rights the relative prices of shares that differ only in their voting rights are modelled in our model voting rights become valuable when a control contest is decided through takeover bids for outside votes the study shows how the value of the voting right depends on the initial ownership distribution the share structure and the ability of the incumbent manager versus a rival for control empirical support for the model is provided using swedish stock market data

excess labor and the business cycle this paper compares the medoff fay estimates of labor hoarding during troughs which are based on data from manufacturing plants with aggregate estimates of excess labor on hand the two sets of estimates seem consistent which provides a strong argument in favor of the excess labor hypothesis this is one of the few examples in macroeconomics where a hypothesis has been so strongly confirmed using detailed micro data this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abstract was borrowed from another version of this item this abs this abstract was borrowed from another version of this item

labor hoarding and the business cycle this paper investigates the sensitivity of solow residual based measures of technology shocks to labor hoarding behavior using a structural model of labor hoarding and the identifying restriction that innovations to technology shocks are orthogonal to innovations in government consumption we estimate the fraction of the variability of the solow residual that is due to technology shocks our results support the view that a significant proportion of movements in the solow residual are artifacts of labor hoarding behavior specifically we estimate that the variance of innovations to technology is roughly 50 percent less than that implied by standard real business cycle models in addition our results suggest that existing real business cycle studies substantially overstate the extent to which technology shocks account for the variability of postwar aggregate u s output

employment tenure and earnings profiles in japan and the united states comments the relationship between job tenure and annual earnings in japan has received considerable attention from social scientists examining employment contracts and the japanese compensation system in their widely cited article masanori hashimoto and john raisian 1985 using data for 1980 showed that japanese men have greater job tenure than comparable workers in the united states and that the earnings of japanese men rise more rapidly with increased tenure they found that an additional year of tenure increases earnings in both small and large firms in japan more than does an additional year of general market experience their results for the united states indicate that general market experience increases earnings more than an additional year of job tenure the 1970 s and 1980 s were a period of substantial change in japanese labor markets due to the rapid aging of the population and the restructuring of the economy following the oil crisis the present analysis extends the work of hashimoto and raisian by estimating earnings equations for japanese men for the years 1971 1976 1981 and 1986 specifically we wish to investigate whether hashimoto and raisian s findings have been stable over time or whether changes in the labor market have altered the importance of tenure relative to total labor market experience in the japanese labor market i changes in the labor market

media capture in a democracy the role of wealth concentration abstract since objective news coverage is vital to democracy captured media can seriously distort collective decisions the current paper develops a voting model where citizens are uncertain about the welfare effects induced by alternative policy options and derive information about those effects from the mass media the media might however secretly collude with interest groups in order to influence the public opinion in the case of voting over the level of a productivity enhancing public bad it is shown that an increase in the concentration of firm ownership makes the occurrence of media bias more likely although media bias is not always welfare worsening conditions for it to raise welfare are restrictive

overconfidence in political behavior this paper studies theoretically and empirically the role of overconfidence in political behavior our model of overconfidence in beliefs predicts that overconfidence leads to ideological extremeness increased voter turnout and stronger partisan identification the model also makes nuanced predictions about the patterns of ideology in society these predictions are tested using unique data that measure the overconfidence and standard political characteristics of a nationwide sample of over 3 000 adults our numerous predictions find strong support in these data in particular we document that overconfidence is a substantively and statistically important predictor of ideological extremeness voter turnout and partisan identification jel c83 d03 d72 d83

excess labour and the business cycle a comparative study of japan germany the united kingdom and the united states against the background of firm specific human capital theory this paper investigates empirically the relative propensity of manufacturing industries in japan germany the united kingdom and the united states to hold excess labour over the business cycle both stock and utilization dimensions of the labour input are integrated into the study throughout discussion is linked to earlier research that has analysed the relative international performance of the japanese labour market

increasing returns labour utilization and externalities procyclical productivity in the united states and japan this paper investigates procyclical productivity and attempts to discriminate among several competing explanations the study focuses on the united states and japan since the different industrial relations in these two economies serve to cast a sharper light on the procyclical productivity debate labour hoarding evaluated through the introduction of a labour utilization proxy proves to be an important influence the interpretation of the role of external economies remains an open issue

inequality and media capture abstract popular support of redistributive policies depends on information they have about the tax system and efficiency of public projects mass media provides a convenient means for manipulating public opinion even when voters understand that the media can be biased i develop a theory of media capture in which the rich can influence information published in a media outlet at a cost the model shows that higher inequality is associated with lower media freedom this effect is stronger in democratic regimes i find empirical support for the model in both panel data and cross country analysis

inventories layoffs and the short run demand for labor this paper presents a theoretical and empirical analysis of the short run employment layoff and inventory strategies of firms on average more than two thirds of all layoffs in american manufacturing end in a rehire by the employer of origin martin feldstein 1975 david lilien 1980 these temporary layoffs have recently accounted for about half of all ongoing employer initiated spells of unemployment in that sector see table 1 and have led to a revised interpretation both of the involuntary nature of these separations costas azariadis 1975 feldstein 1976 martin baily 1977 and of the durability of employment relationships evidently a significant proportion of unemployed workers know that the conditions that generated their separations are temporary and so they expect to be recalled within some reasonable time the point of departure for this paper is in interpreting these findings as evidence of a privately and socially efficient stock of excess capacity held against contingent future demands that is as an inventory of a productive input this view leads to empirically refutable hypotheses regarding both the role of temporary layoffs and the circumstances under which they will be important in particular both excess capacity idle resources and inventories are devices by which firms may economize on the costs of rapid adjustments when faced with unstable market conditions george stigler 1939 in such an environment the demands for layoffs and for other buffer stocks are jointly determined elements of long run technology the choice among alternative stocks will depend on relative profitabilities and firms may choose to hold stocks of inputs as a substitute for inventory accumulation especially if the costs of varying capacity or of storage are important this reasoning implies that i the structure of short run employment and layoff decisions will vary across firms and industries and ii differences in these structures will be systematically related to the role of inventories in firms dynamic strategies some perspective is warranted at least since charles holt et al 1960 economists have recognized the production smoothing role of inventories and the necessity of predicting future demand in making current decisions david belsley 1969 gerald childs 1967 michael ward 1978 similarly one of the contributions of recent work on implicit labor contracts is in viewing the exchange of labor services as a bilateral and durable commitment both these lines of analysis are concerned with the methods firms use to respond to fluctuating demand yet the underlying interrelated nature of employment and inventory decisions has rarely been recognized roger miller 1968 m ishaq nadiri and sherwin rosen 1973 r g crawford 1979 robert hall 1972 this paper aims to provide a framework for evaluating these decisions and in so doing to explain some interesting features of observed labor markets the notion of substitution between inventories of human and physical capital suggests a more disaggregated look at the data table 2 shows the importance of temporary layoffs in the distribution of unemployment among manufacturing industries it reports layoff and total unemployment rates for twelve representative industries over the period 197376 and average layoff rates and recall frequencies for 1958 76 among all 21 twodigit manufacturing industries the correlation between layoff and rehire rates is 6 and the table illustrates this evidently industries with larger than normal layoff rates also tend to have larger rehire frequencies from firm initiated spells of unemployment this university of chicago i am indebted to gary becker robert cotterman sherwin rosen jose scheinkman michael ward finis welch the managing editor and an anonymous referee for discussions and comments at various stages the usual disclaimer applies

accumulation of human capital and the business cycle characteristics of business cycles are quite different across developed countries real wages and working hours are less sensitive to exogenous shocks in the united states than they are in britain and japan using a model with a microeconomic foundation this paper provides an economic explanation of these differences the cost of on the job training plays a crucial role workers seldom quit their jobs when the sunk training cost is high in such economies variances in employment and output become small and shocks tend to be absorbed by working hours and real wages thus these characteristics do not necessarily indicate that the economy is more efficient

toehold strategies takeover laws and rival bidders abstract prior to the announcement of a tender offer the bidding firm is legally allowed to acquire shares in the open market subject to some limitations these pre announcement purchases are known as toeholds this paper presents a simple model that describes the bidder s optimal toehold acquisition strategy within an environment that closely parallels the present legal institutions the model shows that toeholds and bids interact in a complex manner even without the presence of asymmetric information by examining a simple environment the paper provides a useful alternative hypothesis for tests of other presumably more complex models one of the main implications of our model is that if no competing bidders are expected no toeholds should be purchased the paper also demonstrates that the correct specification of an empirical model can be critical for example under some parameter values toehold purchases may exhibit a negative cross sectional correlation with the pre announcement run up in the stock price this occurs even though prices are strictly increasing the size of the toehold several implications concerning various aspects of merger legislation are considered for example we demonstrate that a rule similar to a fair price provision has the desirable property that a second bidder arrives and wins if and only if he places a higher value on the target than the initial bidder

equilibrium adjustment with endogenous information and inventories the paper analyzes the interaction of information acquisition and inventory flexibility with industry adjustment to imperfectly perceived cost and demand disturbances improved information about disturbances reduces the extent to which disturbances are unperceived and dampens the use of inventories reduced inventory flexibility induces firms to devote more resources to acquiring information about disturbances the analysis demonstrates how equilibrium price and output adjustment depend endogenously on the degree of inventory flexibility and other structural parameters influencing the acquisition of information in this paper we analyze how endogenous information acquisition and inventory flexibility influence price and output adjustment in a competitive industry we focus on the potential substitutability of information acquisition for inventory flexibility when disturbances are imperfectly perceived by individual firms the analysis highlights the general issue of how market adjustment depends on structural parameters that influence agents incentives to acquire information there are several reasons why information acquisition may play a role in market adjustment first the rapid development of information technology has enabled firms to gather and process data relevant to production and sales decisions from a greater number of external and internal sources this trend has reduced the costs of forecasting and monitoring factors influencing production and demand conditions for the individual firm relative to those of its competitors as well as for the industry as a whole in particular it has permitted quicker awareness of changing customer demand as well as greater control of the flow of inputs and intermediate goods during the production process this implies that the resources devoted to information acquisition and processing have come to play an important role in firm decisions 2 second improved information about demand and cost conditions may affect the function of inventories inventory adjustment allows a firm s production costs to be smoothed in response to anticipated movements in demand and costs and to be buffered against unanticipated disturbances see ashley and orr 1985 thus

the neglect of correlation in allocation decisions we study the effect of variation in correlation on investment decision in an experimental two asset application comparison of allocations across problems suggests that subjects neglect probabilistic information on the joint distribution of returns and base their allocations on the observed return levels for the two assets when asked to predict future returns subjects try to replicate the historical distribution thereby falling into the probability matching bias predictions drastically vary when correlations become negative while allocations are not significantly affected by changes in sign of correlation the observed allocation patterns contradict the predictions of standard models of choice the inconsistency is attributed to common behavioral bias in financial decision field implications of the results are discussed

on recalls layoffs variable hours and labor adjustment costs abstract the paper analyzes the employment policy of a firm that can vary both hours and the level of employment the analysis differs from previous work in the adjustment cost literature in that the firm is able to change its employment not only through hires layoffs and quits but also by recalls of employees who were previously laid off thus we introduce the possibility of the firm inventorying the labor input it is shown that this labor inventory potential is necessary if the firm is to ever lay off workers further it is demonstrated that linear rather than strictly convex adjustment costs are then required if the firm is to always recall employees who were previously laid off prior to hiring new workers

sunshine as disinfectant the effect of state freedom of information act laws on public corruption abstract we assess the effect of freedom of information act foia laws on public corruption in the united states specifically we investigate the impact of switching from a weak to a strong state level foia law on corruption convictions of state and local government officials the evidence suggests that strengthening foia laws has two offsetting effects reducing corruption and increasing the probability that corrupt acts are detected the conflation of these two effects led prior work to find little impact of foia on corruption we find that conviction rates approximately double after the switch which suggests an increase in detection probabilities however conviction rates decline from this new elevated level as the time since the switch from weak to strong foia increases this decline is consistent with officials reducing the rate at which they commit corrupt acts by about 20 these changes are more pronounced in states with more intense media coverage for those that had more substantial changes in their foia laws for foia laws which include strong liabilities for officials who contravene them for local officials and for more serious crimes conviction rates of federal officials who are not subject to the policy show no concomitant change

the leading shareholder strategy takeover contests and stock price dynamics abstract this paper analyzes the attractiveness of the leading shareholder strategy control without majority ownership for a potential takeover bidder with a cost of raising funds additional purchases commit the bidder to more aggressive behavior in a takeover battle and thus discourage competing bids at the optimum the bidder thus trades off the cost of buying additional shares with the risk of losing control to another bidder small shareholders payoffs depend instead on the relative management skills of the bidders and on the premium they obtain when competing bidders enter the battle this model can also be interpreted in terms of equilibrium ownership of dominant shareholders facing costs of raising funds and risks of takeover attempts
