an empirical study of the consolidation of local public health services in connecticut this study contributes to the literature by empirically examining the decision of connecticut communities to consolidate the delivery of public health services as theory suggests the prospect of scale economies is found empirically to increase the likelihood that a community consolidates public health services in addition differences across communities are found to inhibit the consolidation of public health services overall the results imply that financial incentives may be necessary to encourage more regional districts because localities may underestimate the true minimum efficient scale for public health services and because heterogeneity among jurisdictions impedes regional cooperation

distribution and redistribution in postindustrial democracies this paper analyzes the processes of distribution and redistribution in post industrial democracies we combine a pooled time series data base on welfare state effort and its determinants assembled by huber ragin and stephens 1997 with data on income distribution assembled in the luxembourg income survey lis archive in the case of the lis data we re calculate the micro data in order to remove the distorting influence of pensioners on pre tax pre transfer income distribution we examine the determinants of three dependent variables pre tax pre transfer income inequality post tax post transfer income inequality and the proportional reduction in inequality from pre to post tax and transfer inequality we hypothesized that pre tax pre transfer income inequality would be determined by labor market institutions union density bargaining centralization labor market conditions unemployment and economic structures post industrialism third world imports we hypothesized that the reduction in inequality would be determined by political configurations directly by left government and indirectly via their effect on welfare state generosity by left government and christian democratic government post tax and transfer income inequality was hypothesized to be a product of the combination of labor market variables and political variables the results broadly confirms our hypotheses and the overall fit is very good

spatial differences in the demands for local public goods differences in the mix of public goods across locations are apparent particularly sharp are the differences between public spending habits of central cities and suburbs for 37 of the largest smsas in 1977 the ratio of per capita educational expenditures in central cities to the per capita education expenditures in suburban areas was 93 and the comparable ratio for per capita noneducational expenditures was 2 01 1 relative to suburban areas central cities have spent more of their revenue on noneducational public goods and less on education although these differences have been attributed to various demandand supply side factors analysts have placed considerable emphasis on the demand side determinants of local expenditures researchers such as borcherding and deacon 1972 have estimated the demands for local public goods by focusing on the consumption behavior of the median voter the partial equilibrium nature of these earlier models however missed the potential interdependencies between the demands for public and private goods more recently there have been attempts to develop a more complete general equilibrium model of public choice which incorporates the interaction between public and private goods perkins 1977 presents a general equilibrium extension of the borcherding and deacon framework by testing the cross price effects between various local public goods his empirical results strongly suggest that there is substitutability among certain local public

inventories stock outs and production smoothing if stock outs are ignored and if demand shocks are additive then optimal behaviour requires that the marginal cost of production mc be equated with the expected marginal revenue of increasing expected sales by one unit emr however with more general demand shocks and still ignoring stock outs the excess of mc over emr has the same sign as the covariance of the slope of the demand curve and the marginal valuation of inventory the equality of emr and mc is also broken by taking account of stock outs even if demand shocks are additive if there is a production lag then taking account of stock outs implies that optimal behaviour will be characterized by production smoothing even if the cost of production is linear two alternative definitions of production smoothing are presented and optimal behaviour in the presence of stock outs displays each type of smoothing it is a well known proposition that a firm producing a storable good under conditions of increasing marginal cost will tend to smooth the time profile of its production relative to the time profile of its sales the incentive to smooth production arises from the fact that the cost function is a convex function of the level of production for a given average level of production average costs can be reduced by reducing the variation in production of course if the cost function is linear in the level of production then this incentive to smooth production disappears however we will demonstrate in this paper that if the possibility of stock outs is explicitly incorporated into the firm s dynamic optimization problem i e if we impose a non negativity constraint on inventories and if there is a lag in production then optimal behaviour can be characterized by production smoothing even if the cost function is linear

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

serial correlation in demand backlogging and production volatility this paper explores the idea that stockout avoidance motives together with serial correlation in demand and or the backlogging of excess demand is sufficient to induce firms to behave so that the variance of production exceeds the variance of sales the authors show that the idea holds under a wide range of circumstances facing firms including additive as well as multiplicative demand uncertainty a general form of serial correlation in demand whether inventory and shortage costs apply and whether payment occurs at order or delivery the results greatly enhance the empirical relevance of the idea copyright 1996 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

understanding the inventory cycle abstract careful examination of aggregate data from the u s and other oecd countries reveals that production and inventory behavior exhibit paradoxical features 1 inventory investment is strongly countercyclical at very high frequencies e g 2 3 quarters per cycle it is procyclical only at relatively low cyclical frequencies such as the business cycle frequencies e g 8 40 quarters per cycle 2 production is less volatile than sales around the high frequencies it is more volatile than sales only around business cycle or lower frequencies 3 unlike capital investment or gdp the bulk of the variance of inventory investment is concentrated around high frequencies rather than around business cycle frequencies these features of production and inventory behavior at the low and high frequencies provide a litmus test for inventory theories this paper shows that the stockout avoidance theory kahn j 1987 inventories and the volatility of production american economic review 77 667 679 has much better potential than other competing theories for explaining the seemingly paradoxical features of inventory fluctuations observed at different cyclical frequencies my analysis suggests that demand shocks are the main source of the business cycle

endogenous credible commitment and party competition over redistribution under alternative electoral institutions political parties competing in elections for the power to set public policy face the problem of making credible their policy promises to voters i argue that this commitment problem crucially shapes party competition over redistribution the model i develop shows that under majoritarian electoral rules parties efforts to achieve endogenous commitment to policies preferred by the middle class lead to different behavior and outcomes than suggested by existing theories which either assume commitment or rule out endogenous commitment thus left parties can have incentives to respond to rising income inequality by moving to the right in majoritarian systems but not under proportional representation the model also generates new insights about the anti left electoral bias often attributed to majoritarian electoral rules and the strategic use of parliamentary candidates as a commitment device i find evidence for key implications of this logic using panel data on party positions in 16 parliamentary democracies

inventory and price behaviour the point of this paper is that inventory adjustment attenuates downward pressure on price when realized demand is low because firms accumulate inventory hold overs speculating that demand will be stronger in the succeeding period when realized demand is high the firm draws down its inventories until a stock out occurs and price rises to clear the market

input and output inventories abstract this paper presents a new stage of fabrication inventory model with delivery usage and stocks of input materials that distinguishes between gross production and value added it extends the linear quadratic model of output inventories by adding the joint determination of input inventories empirically input inventories are more important than output inventories maximum likelihood estimation of the decision rules yields correctly signed and significant parameter estimates using data for nondurable and durable goods industries but the overidentifying restrictions of the model are rejected the value added specification dominates because adjustment costs on materials usage are critical to fitting the data

taking stock a critical assessment of recent research on inventories empirical and theoretical aspects of inventory behavior became hot topics in the 1950s and early 1960s no one seemed to notice the tension that was developing between the emerging macroeconomic and microeconomic views of inventories macroeconomists routinely thought of inventories as a destabilizing factor yet the prevailing micro theory viewed inventories as a stabilizing factor it was a fascinating question that was barely explored instead somewhat inexplicably interest in inventories dried up as if inventories were of minor economic significance and little intrinsic interest by the early 1980s then economists once again knew something they had known in the 1950s that inventory investment is of first order importance in business cycles but they were also beginning to realize that the standard production smoothing buffer stock model of inventories was in deep trouble this paper focuses on developments since that realization

s s inventory policies in general equilibrium we study the aggregate implications of s s inventory policies in a dynamic general equilibrium model with aggregate uncertainty firms in the model s retail sector face idiosyncratic demand risk and s s inventory policies are optimal because of fixed order costs the distribution of inventory holdings affects the aggregate outcome in two ways variation in the decision to order and variation in the rate of sale through the pricing decisions of retailers we find that both mechanisms must operate to reconcile observations that orders are more volatile than and inventory investment is positively correlated with sales while remaining consistent with other salient business cycle characteristics the model exhibits strong amplification for some shocks and persistence to a limited extent

price smoothing and inventory this paper explains the phenomenon of price rigidity or price smoothing as the outcome of the optimal inventory policy of a multi period profit maximizing firm under demand and output uncertainties price smoothing may be manifested in two forms first price changes may be moderated with respect to those implied by the demand function and second the firm may choose to restrict price fluctuations by establishing upper and or lower bounds on prices we show that the extent of the asymmetry in price smoothing depends on the relationship between the inventory holding cost and the backlog penalty cost our model accommodates a wide range

why is production more volatile than sales theory and evidence on the stockout avoidance motive for inventory holding this paper argues that the macroeconomically interesting features of inventory behavior are well captured by a model in which firms face only demand uncertainty with a nonnegativity constraint on inventories empirical implications of the stockout avoidance model of inventory behavior are derived and then tested on disaggregated automobile industry data the results largely support the model though they suggest a small role for production smoothing as well subsidiary evidence on the relative variance of demand and cost shocks suggests that demand shocks are indeed more important

what moves parties the role of public opinion and global economic conditions in western europe do western european political parties adjust their ideological positions in response to shifts in public opinion and to changing global economic conditions based on a time series cross sectional analysis of parties ideological dynamics in eight western european democracies from 1976 1998 the authors conclude that both factors influence parties ideological positions but that this relationship is mediated by the type of party specifically they find that parties of the center and right react to both public opinion and the global economy whereas parties of the left display no discernible tendency to respond to public opinion and also appear less responsive to global economic conditions the findings on leftist parties distinctiveness support arguments about these parties long term policy orientations as well as about their organizational structures the authors also find little support for neoliberal convergence arguments

distribution and redistribution the shadow of the nineteenth century the authors present an alternative to power resource theory as an approach to the study of distribution and redistribution while they agree that partisanship and union power are important they argue that both are endogenous to more fundamental differences in the organization of capitalist democracies specifically center left governments result from pr consensus political systems as opposed to majoritarian systems while strong unions have their origins in coordinated as opposed to liberal capitalism these differences in political representation and in the organization of production developed jointly in the early twentieth century and explain the cross national pattern of distribution and redistribution the clusters have their origins in two distinct political economic conditions in the second half of the nineteenth century one in which locally coordinated economies were coupled with strong guild traditions and heavy investment in cospecific assets and one in which market based economies were coupled with liberal states and more mobile assets

municipal government approaches to service delivery an analysis from a transactions cost perspective municipal governments are less likely to contract out for service delivery if citizen preferences for the service are heterogeneous this conclusion is based on an analysis that extends to the public sector the empirical industrial organization literature on transaction costs and the make or buy decision faced by private firms service delivery practices for sixty three municipal services are examined the findings are consistent with the proposition that the cost for writing and monitoring contracts may be an important consideration in municipal service delivery approach and that bureaucratic supply may not be as inefficient as some previous studies indicate

some empirical evidence on the production level and production cost smoothing models of inventory investment the production smoothing model of inventories has long been the basic paradigm within which empirical research on inventories has been conducted the basic hypothesis embedded in this model is that inventories of finished goods serve primarily to smooth production levels in the face of fluctuating demand and convex cost functions however once we allow for shocks to technology and the costs of producing output firms will also use inventories to shift production from periods in which production costs are relatively high to periods in which production costs are relatively low in this sense inventories can serve to smooth production costs rather production levels in this paper we examine the empirical plausibility of the production level and production cost smoothing models of inventories our basic strategy is to derive and contrast a set of unconditional moment restrictions implied by these models in a way that minimizes the role of auxiliary assumptions regarding market structure and industry demand we find overwhelming evidence against the production level smoothing model and very little evidence against the production cost smoothing mode1 we conclude that the variance of production exceeds the variance of sales in most manufacturing industries because the production cost smoothing role of inventories is quantitatively more important than the production level smoothing role of inventories this abstract was borrowed from another version of this item

the production and inventory behavior of the american automobile industry understanding inventory movements is central to an understanding of business cycles this paper presents an empirical study of the behavior of inventories in the automobile industry it finds that inventory behavior is well explained by the assumption of intertemporal optimization with rational expectations the underlying cost structure appears to have substantial costs of changing production as well as substantial costs of being away from target inventory thelatter being a function of current sales given this cost structure whether inventory behavior is stabilizing or destabilizing depends on the characteristics of the demand process in the automobile industry inventory behavior is destabilizing the variance of production is larger than the variance of sales

the politics of inequality voter mobilization and left parties in advanced industrial states why is it that some countries have witnessed significant increases in inequality since the 1960s while at the same time experiencing very little change in the way politics is conducted and why is it that in other countries where inequality has increased much less the left has become substantially more redistributive the answer the authors argue has to do with the interaction between inequality and political mobilization of low income voters the authors make two points in this article first high levels of inequality move left parties to the left second although increasing inequality pushes the core constituencies of left parties to the left it also makes some individuals less likely to be involved in politics the authors argue that left parties will respond to an increase in inequality only when low income voters are politically mobilized they explore these claims through a comparative analysis of left party programs in 10 organisation for economic cooperation and development countries over the period 1966 to 2002

indivisible labor and the business cycle abstract a growth model with shocks to technology is studied labor is indivisible so all variability in hours worked is due to fluctuations in the number employed we find that unlike previous equilibrium models of the business cycle this economy displays large fluctuations in hours worked and relatively small fluctuations in productivity this finding is independent of individuals willingness to substitute leisure across time this and other findings are the result of studying and comparing summary statistics describing this economy an economy with divisible labor and post war u s time series

inventory investment and production in europe during the great recession is there a pattern abstract the paper examines the nexus between inventory investment and the change in aggregate production during the great recession of 2008 09 for 29 european countries a fairly uniform pattern emerges inventory investment is positively correlated with changes in production and follows the latter with a time lag of two to three quarters very few countries austria greece spain and switzerland diverge from the typical pattern this might hint to problems with respect to data quality

nonconvex costs and the behavior of inventories this paper explores one possible explanation for the apparent excess volatility of production relative to sales nonconvexities in the technology facing firms it is shown that if firms operate in a region of declining marginal costs then small shifts in demand can cause production to jump substantially estimates for six production to stock industries as well as the automobile industry suggest that all these industries behave as if they were operating in the region of nonconvex costs the results have important implications not only for inventory investment but also for the cyclical behavior of productivity and prices

who gives who gains progressivity and preferences the extent to which popular support for the welfare state depends on income varies greatly across nations and policy domains we argue and show formally that these variations largely overlooked yet essential to understanding the politics of redistribution reflect in part the design of tax and transfer policies in terms of progressivity when progressivity is high politics is perceived by income groups as a zero sum game and conflicts over who gets what intensify when progressivity is low and tax contributors and benefit recipients overlap redistributive struggles become politically less salient we test these predictions both across nations and across policy domains within a sample of advanced industrial democracies our findings indicate that the progressivity of the tax and transfer system is a major determinant of the predictive power of income on preferences for redistribution

globalization party positions and the median voter the authors argue that the effects of economic globalization on social democratic parties in western europe are conditional on the position of the median voter if the median is far enough to the right such parties will adopt business friendly policies because they are required to win office only when the median is relatively far to the left will globalization constrain social democratic parties forcing them to adopt policies further to the right in order to retain credibility it is on this basis the authors argue that empirical studies are misspecified unless they include an interaction between measures of globalization and the position of the median in addition to presenting formal theoretical arguments the article reports empirical findings from fifteen countries in the period from 1973 to 2002 that support the conclusion that the effects of globalization are indeed contingent on the median the authors find that the effects of globalization are significant for social democratic parties only in circumstances in which the median is relatively far to the left

voting for income immiserizing redistribution in the meltzer richard model this paper argues that income received via redistributive transfers unlike labor income requires no direct sacrifice of leisure this makes it attractive to many voters even if it leaves them poorer this point is made within the classic meltzer and richard 1981 model wherein heterogeneous voters evaluate an income redistribution program that finances a lump sum transfer to all via a distorting income tax the politicalequilibrium policy under majority rule is the tax most preferred utility wise by the median voter she and many poorer voters may support income redistribution that ironically leaves them poorer in income terms but with higher utility jel h2 e6 d

inventories and the business cycle an equilibrium analysis of s s policies we develop an equilibrium business cycle model where nonconvex delivery costs lead firms to follow s s inventory policies calibrated to postwar us data the model reproduces two thirds of the cyclical variability of inventory investment moreover it delivers strongly procyclical inventory investment greater volatility in production than sales and a countercyclical inventory to sales ratio our model challenges several prominent claims involving inventories including the widely held belief that they amplify aggregate fluctuations despite the comovement between inventory investment and final sales gdp volatility is essentially unaltered by inventory accumulation because procyclical inventory investment diverts resources from final production thereby dampening fluctuations in sales

redistribution and the income of the median voter the income of the median voter has been measured by median income this measure fails to consider the income distribution of both voters and number of adults per family proper measures of the income of the median voter change standard results this income is no longer less than mean income its ratio to mean income is only slightly related to the ratio of median to mean income

inequality social insurance and redistribution is the political support for welfare policy higher or lower in less egalitarian societies we answer the question using a model of welfare policy as publicly financed insurance that pays benefits in a redistributive manner when voters have both redistributive and insurance motives for supporting welfare spending the effect of inequality depends on how benefits are targeted greater inequality increases support for welfare expenditures when benefits are targeted to the employed but decreases support when benefits are targeted to those without earnings with endogenous targeting support for benefits to those without earnings declines as inequality increases whereas support for aggregate spending is a v shaped function of inequality statistical analysis of welfare expenditures in advanced industrial societies provides support for key empirical implications of the model

inventories and the volatility of production a stylized fact associated with inventory behavior is that the variance of production exceeds the variance of sales this paper presents a model of production decisions with demand uncertainty that incorporates no nnegativity constraints on inventories even with no productivity shocks optimal behavior by the firm is consistent with this stylized fact either if demand exhibits positive serial correlation or if the firm can backlog excess demand the reason is that a demand shock affects both the actual inventory level given unchanged production and the desired level production must replenish the stock and adjust to the new desired level copyright 1987 by american economic association

positional deprivation and support for radical right and radical left parties we explore how support for radical parties of both the left and right may be shaped by what we call positional deprivation where growth in income of individuals at a given point in the income distribution is outpaced by income growth elsewhere in that distribution we argue that positional deprivation captures the combination of over time and relative misfortune that can be expected to distinctly spur support for radical left and right parties we explore this possibility by matching new measures of positional deprivation to individual level survey data on party preferences in 20 european countries from 2002 to 2014 we find that positional deprivation is robustly correlated with supporting radical populist parties first positional deprivation generally measured as average income growth across deciles of a country s income distribution minus a respondent s own decile s growth is associated with respondents retreat from mainstream parties and with support for both radical right and particularly radical left parties second positional deprivation relative to the highest and the lowest ends of the income spectrum play out differently for radical right and for radical left support a respondent s positional deprivation relative to the wealthiest decile s growth in his or her country tends to spur support for radical left but not radical right parties in contrast positional deprivation relative to the poorest decile s growth in a respondent s country tends to spur support for radical right but not left parties the results suggest that the combination of over time and relative economic misfortune may be key to how economic experience shapes radical backlash of the left and right

political jurisdictions in heterogeneous communities we investigate whether political jurisdictions form in response to the trade off between economies of scale and the costs of a heterogeneous population we consider heterogeneity in income race ethnicity and religion and we test the model using american school districts school attendance areas municipalities and special districts we find strong evidence of a trade off between economies of scale and racial heterogeneity we also find evidence of a trade off between economies of scale and income heterogeneity conversely we find little evidence that ethnic or religious heterogeneity shapes jurisdictions to clarify the direction of causality between heterogeneity and jurisdictions we exploit shocks to racial heterogeneity generated by the two world wars

institutions partisanship and inequality in the long run it has been widely suggested by political scientists and economists based on empirical evidence for the period since 1970 that the institution of centralized wage bargaining and the presence of a government of the left are associated with lower levels of income inequality the authors make use of new data on top income shares as well as long run series on wage inequality to examine the effects of partisanship and wage bargaining over a much longer time period nearly the entire twentieth century their empirical results provide little support for the idea that either of these two factors is correlated with income inequality over this period they then show that a closer look at the introduction of centralized wage bargaining in individual countries during the middle part of the twentieth century reveals that in countries that moved to centralize wage bargaining income inequality had already been trending downward well before the institutional change that the move to centralized bargaining did not alter this trend and that these changes in income inequality were also observed in countries that did not adopt centralized wage bargaining at this time the results suggest that there were alternative institutional paths to reduced income inequality during most of the twentieth century this raises the possibility that either structural economic changes or commonly shared economic and political events such as world wars and economic crises may ultimately be more important for understanding the evolution of income inequality than are the institutional or partisan characteristics commonly considered to be decisive by political scientists

the distinction between inventory holding and stockout costs implications for target invemtories asymmetric adjustment and the effect of aggregation on production smoothing this paper shows that differences between the costs of holding inventories and the costs of incurring stockouts provide a convenient theoretical distinction between production to stock and production to order industries furthermore differences in holding and stockout costs can cause a firm to replenish inventories following a positive demand surprise at a different speed than it reduces stocks following unexpectedly low sales this asymmetric adjustment lessens the tendency for firm specific production shocks to cancel out in aggregation and can cause industry output to be more variable than industry sales even when representative firms exhibit production smoothing behavior copyright 1994 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

externalities vs internalities a model of political integration abstract decentralized government leads to inter regional externalities whereas an integrated jurisdiction solves the externality problem centralized government entails other costs in particular a neglect for minority interests the paper models formally the trade off between these two forces in determining the optimum as well as the equilibrium design of jurisdictions both the relative size of regions and the distribution of tastes are shown to be important parameters of the problem

local government consolidations the impact of political transaction costs local government in norway comprises a large number of small municipalities cost efficiency can be improved by consolidating local authorities and central government has designed a framework to stimulate voluntary mergers existing theories suggest that political transaction costs will impede consolidations 1 generous grants compensate diseconomies of scale central government has promised small municipalities that grant levels will be maintained but policy promises may not be credible 2 property rights to local revenues are nullified when consolidations have been implemented high revenue municipalities will therefore go against merger with a poorer neighbor 3 a consolidated local council may be composed of different political parties and it may therefore pursue other policies than an existing council expected changes in party strength can lead municipalities to oppose a proposed consolidation 4 senior politicians are less likely to support mergers particularly if they come from small polities

centripetal and centrifugal incentives in electoral systems this paper investigates how electoral laws affect the position taking incentives of parties and candidates it seeks to extend the finding presented in the classical median voter theorem to a wide class of electoral systems or to show the limits of such extension the factors examined are the district magnitude the electoral formula the number of votes each voter is allowed to cast whether voters can cumulate their votes and whether voters can partially abstain i suggest a crude division of electoral systems into those producing predominantly centripetal incentives and those producing predominantly centrifugal incentives among the factors found to produce centripetal incentives at least in noncumulative systems are the following increases in the number of votes per voter outlawry of partial abstention and decreases in the district magnitude in systems allowing the cumulation of votes matters are a bit different

how closely do top income shares track other measures of inequality in recent years researchers have used taxation statistics to estimate the share of total income held by the richest groups such as the top 10 or the top 1 compiling a standardised top income shares dataset for 13 developed countries i find that there is a strong and significant relationship between top income shares and broader inequality measures such as the gini coefficient this suggests that panel data on top income shares may be a useful substitute for other measures of inequality over periods when alternative income distribution measures are of low quality or unavailable

on the number and size of nations this paper studies the equilibrium determination of the number of countries in different political regimes and in different economic environments with more or less economic integration we focus on the trade off between the benefits of large jurisdictions and the costs of heterogeneity of large and diverse populations our model implies that i democratization leads to secessions ii in equilibrium one generally observes an inefficiently large number of countries iii the equilibrium number of countries is increasing in the amount of economic integration

earnings inequality and welfare spending a disaggregated analysis the welfare state is generally viewed as either providing redistribution from rich to poor or as providing publicly financed insurance both views are incomplete welfare policies provide both insurance and redistribution in varying amounts depending on the design of the policy the authors explore the political consequences of the mix of redistribution and insurance in the context of studying the impact of income inequality on expenditures in different categories of welfare spending in advanced industrial societies from 1980 to 1995 they find that spending on pensions health care family benefits poverty alleviation and housing subsidies is largely uncorrelated with income inequality but that spending on income replacement programs such as unemployment insurance sickness pay occupational illness and disability are significantly higher in countries with more egalitarian income distributions they show that this pattern is exactly what a theory of political support for redistributive social insurance programs would predict

political reinforcement how rising inequality curbs manifested welfare generosity we propose a political reinforcement hypothesis suggesting that rising inequality moves party politics on welfare state issues to the right strengthening rather than modifying the impact of inequality we model policy platforms by incorporating ideology and opportunism of party members and interests and sympathies of voters if welfare spending is a normal good within income classes a majority of voters moves rightward when inequality increases as a response the left in particular shift their welfare policy platform toward less generosity we find support for our arguments using data on the welfare policy platforms of political parties in 22 oecd countries

inventories and sticky prices more on the microfoundations of macroeconomics the role of inventories in making prices sticky is studied by analyzing a dynamic linear quadratic model of a monopoly firm facing stochastic demand but able to store its finished goods in inventory it is shown that in contrast to the usual presumption firms that exhibit the smallest output responses to demand fluctuations may also exhibit the smallest price fluctuations specifically firms which have very flexible inventory storage facilities or are subjected to very transitory demand shocks will rely on inventories as buffers and will change neither production nor price very much on the other hand firms which have very inflexible storage facilities or whose demand shocks are quite permanent will display large swings in both price and output the standard assumption about inventory carrying costs that has been used in the literature that they are linear is shown to imply that production is impervious to fluctuations in demand it is also established that prices may respond more strongly to positive demand shocks than to negative ones if it is impossible to hold negative inventories i e to have unfilled orders the model offers an explanation for stickiness in relative prices however under certain circumstances it may help explain the persistence of inflation this abstract was borrowed from another version of this item

can the production smoothing model of inventory behavior be saved the production smoothing model of inventory behavior has a long and venerable history and theoretical foundations that seem very strong yet certain overwhelming facts seem not only to defy explanation within the production smoothing framework but actually to argue that the basic idea of production smoothing is all wrong most prominent among these is the fact that the variance of detrended production exceeds the variance of detrended sales this paper first documents the stylized facts then it derives the production smoothing model rigorously and explains how the model can be amended to make it consistent with the facts finally it reviews the theoretical and empirical evidence and tries to draw some tentative conclusions

real business cycles in this paper we demonstrate how certain very ordinary economic principles lead maximizing individuals to choose consumption production plans that display many of the characteristics commonly associated with business cycles our explanation is entirely consistent with i rational expectations ii complete current information iii stable preferences iv no technological change v no long lived commodities vi no frictions or adjustment costs vii no government viii no money and ix no serial dependence in the stochastic elements of the environment we also provide a completely worked out example of the type of artificial economy we have in mind the time series properties of the example exhibit some major features of observed business cycles although this type of model may not be capable of explaining all of the regularities in actual business cycles we believe that it provides a useful well defined benchmark for assessing the relative importance of factors e g monetary disturbances

financing constraints and inventories abstract this paper investigates the impact of financing constraints on firms inventory and cash management in particular it examines the extent to which the presence of such constraints may account for certain empirical regularities these include e g the excess variance of production vis a vis that of sales as well as the counter cyclicality and persistence of the inventory sales ratio we model the intertemporal decision making on production cash retention and dividends of a firm that is exposed to stochastic demand shocks in every period and faces constrained access to external sources of finance it is found that the presence of financing constraints can explain the excess variance of production in a model which otherwise would not deliver this result moreover as long as demand is positively serially correlated they also contribute to the counter cyclicality and persistence of the inventory sales ratio the paper suggests that financing constraints should not be discarded as a factor driving the cyclical behaviour of inventories
