optimal state dependent rules credibility and inflation inertia abstract we use a state dependent model where pricing rules are optimal to examine the costs of a money based disinflation under various assumptions about the credibility of the policy change our analysis allows us to relate actual credibility and future inflation inertia to the asymmetry of the price deviation distribution an important implication of our state dependent setting is that disinflation can be attained without substantial cost even in a situation of low credibility provided that a mechanism of price alignment eliminates the asymmetry of the price deviation distribution we also develop an analytical framework for analyzing intermediate imperfect credibility cases

reinterpreting the role of inflation in politico economic models the author attempting to analyze the interplay between politics and economics is faced with a large number of problems ranging from an always too small and idiosyncratic data set to the lack of any generally accepted theory of the process which has testable implications my aims have been 1 to show that past studies have typically treated inflation in an extremely naive way disregarding the fact that it may have political pluses if unanticipated and 2 to test the sensitivity of established formulations to what i believe is the more useful view of voter behavior given in model ii since model i and model ii represent polar extremes of amnesiac and eidetic behavior tests of intermediate lag structures are clearly in order because of administration peculiarities however lost data points will pose a serious problem

international marketing ethics from an islamic perspective a value maximization approach international marketing practices embedded in a strong ethical doctrine can play a vital role in raising the standards of business conduct worldwide while in no way compromising the quality of services or products offered to customers or surrendering the profit margins of businesses adherence to such ethical practices can help to elevate the standards of behavior and thus of living of traders and consumers alike against this background this paper endeavors to identify the salient features of the islamic framework of international marketing ethics in particular it highlights the capabilities and strengths of this framework in creating and sustaining a strong ethical international marketing culture at the heart of islamic marketing is the principle of value maximization based on equity and justice constituting just dealing and fair play for the wider welfare of the society selected key international marketing issues are examined from an islamic perspective which it is argued if adhered to can help to create a value loaded global ethical marketing framework for mncs in general and establish harmony and meaningful cooperation between international marketers and muslim target markets in particular

expected monetary changes and relative prices a look at evidence from the stock market at the heart of the natural rate theory is the assumption that fully perceived monetary growth is neutral with respect to relative price changes unfortunately there have been few attempts to test this assumption directly because the belief that active contracyclical monetary policies are not superior to friedman s constant growth rule rests upon the assumption that expected monetary changes have neutral relative price effects more evidence is needed on whether such changes are in fact neutral to this end we test the hypothesis that only the unexpected components and not the expected components of monetary changes affect relative price changes by looking at the stock market testing is done on a modification of the well known mean variance capital asset pricing model the capm specifically we modify the capm to allow for differential stock returns depending upon expected and unexpected monetary growth rates section ii explains the basic model used to test for non neutral relative price effects of monetary change section iii deals with the empirical definitions of expected and unexpected money growth section iv discusses the basic data while sections v and vi make neutrality tests of monetary growth using actual expected revisions in expected and unexpected money growths the last part summarizes the paper

relative price variability and inflation evidence from us cities we test whether the time series positive correlation of inflation and intermarket relative price variability is also present in a cross section of u s cities we find this correlation to be a robu

inflation inflation uncertainty and relative price dispersion evidence from bivariate garch m models abstract one potential real effect of inflation is its influence on the dispersion of relative prices in the economy menu cost models generally imply that higher trend inflation will increase price dispersion in contrast signal extraction models predict that increased inflation uncertainty will raise relative price dispersion existing empirical studies do not distinguish between these separate hypotheses we constuct a bivariate garch m model of inflation and relative price dispersion to test these differing explanations in a single model and find that inflation uncertainty dominates trend inflation as a predictor of relative price dispersion

inflation and the distribution of price changes this paper reconsiders the empirical evidence connecting inflation to its higher order moments in particular we examine the statistical properties of the observed positive correlation between the sample mean and the sample cross sectional skewness of price changes this correlation has attracted substantial attention over the years and has recently been the focal point of a debate among macroeconomists we show that the sample mean skewness correlation suffers from a small sample bias that accounts for the entirety of the observed correlation in other words we establish that one of the stylized facts in the literature on aggregate price behavior need not be a fact at all

relative price variability inflation and the allocative efficiency of the price system abstract this paper develops a theory of the relationship between aggregate and relative price variability based on the inability of people even in a rational world to identify permanent changes in relative demands whether caused by real or by monetary variability and relative productivities as soon as they occur the theory implies that the variance of the rate of inflation and the variance of relative price change are positively related although expectations are rational and markets always clear production decisions respond sluggishly to changes in relative prices temporary shocks to relative demands cause prolonged changes in the structure of production available information is used so as to maximize the efficiency of the price system however this efficiency decreases when any of the underlying variances increases this decrease is more pronounced when the production lag is longer

the relationship between relative prices and the general price level it is very nearly a truismi amaong neoclassical economists that the public is wont to confuse changes in the general price level with relative price changes correspondingl y one might speak of the independence between the two as one of the central postulates of the neoclassical tradition william stanley jevons was aml ong the first to identify this basic dichotomin economic life as well as to attempt to explain the ordinary citizen s seenming incapacity to understand it

comparing time series and survey forecasts of weekly changes in money a methodological note measured as the difference between the announced change and the expected change derived from the money market services inc weekly survey of government securities dealers unlike other survey measures of expectations the most notable example of which is the livingston survey data these expectations are formed by active market participants consequently the survey s forecast made public before the fed s announcement of the actual change in the money stock is commonly thought to represent the market s expectation the concern in this paper is not with the impact of unanticipated money changes on nominal interest rates the purpose is to compare the relative forecasting abilities of the survey predictions and those obtained from a timeseries model this question is of interest because the weekly money series used in previous research includes certain abnormal weeks in which exogenous factors may significantly alter the series stochastic properties see for example cornell 1 urich and wachtel 9 thus the influence of these abnormal weeks weeks that include benchmark revisions changes in seasonal factors and weeks in which there is a social security effect is examined by comparing forecasting results for two samples one includes these weeks and the other deletes them following pearce 6 this approach allows us to test the hypothesis that the survey responses are at least weak form rational and to see how sensitive this test is to the sample of weeks used unlike previous studies we use two survey forecast series the median forecast made public prior to the announced change in ml and the mean series constructed from individual respondents forecasts zarnowitz s 10 examination of the asa nber survey forecasts indicates that the mean forecast is on average statistically superior to the median this finding is based on the idea that the mean forecast uses a more informationally diverse data set consequently it is

cross cultural equity evaluations a questionnaire experimental approach abstract the theoretical background of the empirical investigations to be reported in this paper are positionalist aggregation functions which are numerically representable the broad borda rule is proposed as an aggregation mechanism for the case of a complete profile of the so called individual extended orderings we modify this rule to reflect considerations of equity students from germany israel the baltic states austria and slovenia were confronted with questionnaires that describe situations most of which reflect different aspects of needs all situations start from the preference structure which underlies an equity axiom we are focussing on the following three points a what is the percentage of respondents satisfying the equity axiom b how often do the students revise their initial decision when more and more people join the side of the more advantaged c are there major differences across countries and cultures

supply chain coordination in spatial games abstract the notion that economies consist of the systems of cities originates from a theory by christaller and beckmann based on a lochean framework of retailers having an endogenously determined market area in 1968 it was completed by tinbergen who has suggested production approach this original theory explains the location pattern of the market and manufacturing centers selling goods to the local populations within given market areas the theory was based on the idea of the urban area being a trading center our paper influenced by the ideas presents the quantitative method of building up the model of spatial hierarchy as the result of spatial games the paper by girlich on the metric transportation problems and their solution inventory modelling lecture notes of the international postgraduate summer school vol 2 isir budapest portoro 1995 pp 13 24 gives us proper foundations for our present research in this paper customer traveling problem is described which helps us to define a market area a mathematical description of market areas defines the border between two areas under the assumption of shortages of goods in at least one market area the study is influenced by grubbstrom s work on mrp optimization for details see r w gubbstrom management science 13 7 1967 558 567 the mathematical scientist 16 1991 118 129 international journal of production economics in press international encyclopaedia of business and management routledge london 1996 r w grubbstrom a bogataj eds storlien 1997 fpp portoro 1998 r w grubbstrom a molinder international journal of production economics 35 1994 289 311 in our paper the problem is formulated as a non constant sum game which is the case of the total market area being constant and the conditions for lower central places described for different positions of this central place in an urban hierarchy in the case of two level production differential games are suggested when the total market area changes over the time

approaches to inequality of opportunity principles measures and evidence we put together the dierent conceptual issues involved in measuring inequality of opportunity discuss how these concepts have been translated into computable measures and point out the problems and choices researchers face when implementing these measures our analysis identies and suggests several new possibilities to measure inequality of opportunity the relevance of the conceptual issues and modelling choices are illustrated with ndings from the empirical literature on income inequality of opportunity

distributive justice theoretical foundations and empirical findings abstract the first part of this paper discusses various theories of distributive justice such as utilitarianism rawlsianism approaches within cooperative bargaining theory and the notion of fair allocations the focus is on the different informational bases used in these solution concepts the second part reports some results from empirical investigations where a particular distributive problem had to be solved by undergraduate students of economics and business administration the question we are posing is whether the respondents behaviour can to some extent at least be rationalized in terms of utilitarian ethics

stochastic properties of a production inventory process with planned production using transform methodology abstract we consider a stochastic inventory process in which demand is generated by individual events separated by independent stochastic time intervals whereas production takes place in batches of possibly varying sizes at different points in time the resulting processes are analysed using laplace transform methodology expressions for inventory and stockouts are developed applying the theory of residues an example includes poisson distributed demand intervals assuming costs for set ups for carrying inventory and for stockouts conditions are developed for determining the optimal production policy on the one hand when applying the traditional average cost measure on the other when applying the annuity stream principle

when is inequality fair an experiment on the effect of procedural justice and agency abstract we investigate how the perceived fairness of an income distribution depends on the beliefs about the process that generates the inequality specifically we examine how two crucial features of this process affect fairness views 1 procedural justice equal treatment of all 2 agency one s ability to determine his her income we do this in a lab experiment by differentially varying subjects ability to influence their earnings comparison of ex post redistribution decisions of total earnings under different conditions indicate both agency and procedural justice to matter for fairness highlighting the importance of agency we observe lower redistribution of unequal earnings resulting from risk when risk is chosen freely highlighting the importance of procedural justice we find introduction of inequality of opportunity to significantly increase redistribution despite this increase under inequality of opportunity the share of subjects redistributing none remain close to the share of subjects redistributing fully revealing an underlying heterogeneity in the population about how fairness views should account for inequality of opportunity

on the real effects of short and long run inflation and relative sector price variability some empirical evidence using the kalman filter this paper evaluates empirically the effects of sector relative price variability and short run and long run inflation on the growth rate of real output in the united states since 1947 also permanent and transitory estimates are constructed to evaluate the effects of unanticipated movements in sector relative price on the growth rate of real output the results show a statistically significant inverse relationship beween the growth rate of real output and transitory sector relative price variability and anticipated long run inflation and a direct relationship between the growth rate of real output and unanticipated short run inflation

moral hypocrisy power and social preferences abstract we study how individuals adjust their judgment of fairness and unfairness when they are in the position of spectators before and after making real decisions and how this adjustment depends on the actions they take in the game we find that norms that appear universal instead take into account the players bargaining power also individuals adjust their judgments after playing the game for real money when they behaved more selfishly and only in games where choices have no strategic consequence we interpret this possibly self deceptive adjustment of judgments to actions as moral hypocrisy this behavior appears produced by the attempt to strike a compromise between self image and payoffs so as to release oneself of one s responsibility for selfish behavior

conditional relative price variance and its determinants open economy evidence from germany the authors present empirical tests of two hypothesis derived from an open economy version of the multimarket equilibrium model the first hypothesis holds that the conditional relative price variance is positively related to the variance of domestic monetary and foreign nominal and real shocks the second hypothesis claims a negative impact of an increase in conditional relative price variance on normal output in contrast to earlier studies the authors use direct measures of conditional relative price variance based on arch estimates the authors results show that both hypotheses are consistent with german data copyright 1991 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

conglomerate mergers as defense against the risk of relative price variability this paper studies the effects of the risk of relative price variability on the optimal structure of a firm s cash flows with an application of portfolio theory it is suggested that when relative price risk is greater it is optimal for the management to diversify at the margin and emphasize economies of scale or scope when the risk is smaller conglomerate mergers should therefore be positively associated with relative price risk given the variables affecting mergers as a whole empirical evidence is found to lend support to the theory the inflation rate explains conglomerate mergers even better which suggests that relative price risk may constitute another real resource cost of inflation

interpreting the correlation between inflation and the skewness of relative prices a comment on bryan and cecchetti large literature in macroeconomics has examined how the inflation rate is related to the distribution of relative price changes this work has established a striking fact there is a strong correlation between inflation and the skewness of this distribution when inflation is high the distribution of relative price changes is typically skewed to the right when inflation is low it is skewed to the left the oil shocks of the 1970s are one example of this phenomenon inflation rose while a few goods oil products experienced especially large relative price increases but the inflationskewness correlation is not just a result of oil shock years this fact holds for many time periods and many countries e g vining elwertowski 1976 and ball mankiw 1995 for the united states amano macklem 1997 for canada de abreu lourenco and gruen 1995 for australia bryan and cecchetti 1999 argue that this fact need not be a fact at all because of small sample bias if true this is an important claim it would eliminate an apparently robust stylized fact that might otherwise hold a clue to understanding the causes or effects of inflation we are not however convinced by bryan and cecchetti s assertion our goal in this note is to explain why on its face bryan and cecchetti s claim is puzzling their paper presents a model in which there is an underlying true distribution of price changes and the observed distribution is obtained by sampling a subset of these price changes they show that the skewness of the sample distribution may be correlated with the sample mean even if there is no skewness in the population distribution this model however does not capture the reality of how price indices are constructed it is not the case that there are a large number of sectors and the government computes the cpi by sampling a small number of them instead the government measures prices in all sectors of which there may be a small or large number depending on the level of disaggregation the observed correlation of the mean and skewness is based on the full population of sectors so small sample bias does not appear to be possible because the data used to construct price indices are comprehensive one cannot avoid the conclusion that the inflation skewness correlation is a fact 1 if the idea of small sample bias is not relevant here how should one interpret the numerical simulations presented by bryan and cecchetti the substance of their argument we believe is that it is easy to explain the correlation between inflation and skewness previous authors have worked hard to explain this fact ball and mankiw 1995 propose that this correlation can be explained with menu cost models of price adjustment while balke and wynne 1996 argue that it can be explained by a multisector real business cycle model by contrast bryan and cecchetti generate the inflation skewness correlation in a much simpler model although it would be wrong to interpret their results as showing that the correlation doesn t exist one could plausibly interpret them as showing that this correlation doesn t prove anything as they put it such statistics are not useful in distinguishing sticky from flexible price setting behavior in macroeconomic models to evaluate this argument it helps to step back and review the motivation behind the ball mankiw and balke wynne theories the starting point for these authors is the classical theory of price determination central to this theory is the classical dichotomy relative prices are determined by real factors and the aggregate price level is determined by monetary factors specifically if there are n sectors in the economy there are n 1 relative prices real variables such as shifts in demand and costs in the various sectors determine these n 1 prices using any good or combination of goods as the numeraire the aggregate price level is determined by the supply and demand for money this idea is summarized by the quantity equation mv 5 py the n 1 relative prices and the price level which equals the average of all nominal prices together determine the n nominal prices in this classical model there is no obvious reason that the behavior of the aggregate price level is related to the distribution of relative prices if m v and y remain constant then p is constant and any shifts in the distribution of relative prices do not influence the price level to explain the observed inflation skewness correlation one must explain how the economy differs from this classical baseline balke and wynne offer one story for the inflationskewness correlation in their model certain shocks to the economy generate both skewness in the relative price distribution and changes in aggregate output for instance when opec raised oil prices relative prices in energy related sectors rose by 50 or more balanced by smaller relativeprice decreases in the rest of the economy this generated

privatization and changes in welfare costs of inflation the case of entel argentina abstract in a country with permanent deficit driven inflation problems the proceeds from privatization may translate into potential reductions of the seigniorage needed to finance a given a level of government expenditure the changes in welfare costs of inflation brought about by divestiture are quantified in a monetary model in an argentine case study these changes were found to be small both in terms of gdp and as a percentage of seigniorage revenue within the model this is mainly explained by the low values encountered for the elasticities of money demand with respect to expected inflation and by the exclusion of considerations about unanticipated inflation

on inflation and real price variability this paper studies the consequences of costly price adjustments for the variability of real prices accompanying inflation for constant elasticity demand and cost of production it is shown that a higher demand a lower cost of production or a lower cost of price adjustment leads to less intertemporal variability of real prices if the marginal cost of production does not increase too fast then the average real price is less than the real price that would prevail in the absence of inflation additionally a higher demand a lower cost of production or a lower cost of price adjustment leads to a higher level of real prices

inflation and relative price variability in yugoslavia abstract granger causality tests show that inflation granger causes relative price variability but the feedback relationship cannot be excluded

variability of inflation and the dispersion of relative prices evidence from the chinese hyperinflation of 1946 1949 abstract this paper uses data from the chinese hyperinflation of 1946 1949 to focus on the relationship between the variability in the general price level and the dispersion in relative prices the issue is important because it bears on the natural rate hypothesis which supports the postulate that these two monetary variables are independent our results reinforce the bulk of previous evidence which suggests a positive correlation between the variation in inflation rate and the dispersion in relative prices during inflationary episodes

relative price changes as aggregate supply shocks this paper proposes a theory of supply shocks or shifts in the short run phillips curve based on relative price changes and frictions in nominal price adjustment when price adjustment is costly firms adjust to large shocks but not to small shocks and so large shocks have disproportionate effects on the price level therefore aggregate inflation depends on the distribution of relative price changes inflation rises when the distribution is skewed to the right and falls when the distribution is skewed to the left we show that this theoretical result explains a large fraction of movements in postwar u s inflation moreover our model suggests measures of supply shocks that perform better than traditional measures such as the relative prices of food and energy

a proposition on short run departures from the law of one price unanticipated inflation relative price dispersion and commodity arbitrage abstract this paper proposes an explanation of short run departures from the law of one price based on the characteristics of the inflationary process and changes in the distribution of relative prices unexpected inflation gives rise to volatility of relative prices the more unexpected and hence uneven the rate of inflation the greater the difficulty in discerning from a given structure of relative prices commodity arbitrage opportunities which may be expected to persist and those transient opportunities which do not warrant a firm s incurring fixed costs of arbitrage an illustration portrays a risk averse firm confronting an international arbitrage opportunity

measuring unfair in equality abstract this paper shows one way of generalizing the standard framework of inequality measurement to allow for a distinction between fair and unfair inequalities we introduce the unfairness lorenz curve and the unfairness gini which are generalizations of the standard versions of the lorenz curve and the gini with this more general framework in place we study the implications of responsibility sensitive theories of justice for the evaluation of the income distribution in norway from 1986 to 2005 we find that both the pre tax and the post tax income distributions have become less fair in norway even though the standard gini for the pre tax income distribution has decreased in the same period two trends explain this development the increase in income share of the top percentile and the change in the situation of females in the labor market the concentration of income at the top of the distribution contributes both to increased unfairness and increased inequality whereas the increase in females working hours and level of education primarily contributes to a reduction in inequality thus the latter effect dominates for the standard gini and the former effect for the unfairness gini furthermore we find that the increase in post tax unfairness is even larger than the increase in pre tax unfairness which shows that the tax system in norway contributes less to eliminating unfairness in 2005 than in 1986

market structure and price flexibility abstract the relationship between market form and price adjustment patterns is examined by using disaggregated price data for mexico over the 1940 1984 period frequency of price adjustment and characteristics of goods and industries appear to be related as predicted by menu cost and customer market models the pattern of response followed by individual prices to inflationary shocks is related to their frequency of price adjustment the typical pattern of response to small and large shocks may differ contrary to predictions based on models with overlapping contracts in addition the empirical results have implications for the relationship between inflation and relative price variability

the study of optimal additional investments in capacities for reduction of delays in value chain abstract in this paper special attention is paid to the controllability and control of optimal investment actions model of supply chains for studying the influence of additional investments in time delay reductions which maximize the net present value npv of value chain the findings about npv approach to safety stocks in planned production and especially in multi level mrp system that has been considered by grubbstrom r w 1998 a net present value approach to safety stocks in planned production international journal of production economics 56 57 213 229 1999 a net present value approach to safety stocks in a multi level mrp system international journal of production economics 59 361 375 have been here of special interest for strategic analysis

inflation and relative price variability in the open economy this paper explores the determination of relative price variability in a small open economy operating under a fixed exchange rate a central ingredient of the model presented is the distinction made between traded and non traded goods this distinction leads to a decomposition of total variability into three components the variabilities within each set of goods and between the two sets the analysis also emphasizes the effects of expected versus unexpected inflation on the variability of relative prices the model is tested using annual data for mexico covering the 1951 76 period

intercountry differences in the relationship between relative price variability and average prices this paper provides new evidence on the relationship between relative price variability and inflation the model uses a consistently defined data set for nine european countries it benefits from the inclusion and testing of the effects of macroeconomic variables and the incorporation into the measures of inflation and dispersion adjustments for timeliness appropriate formulas and proximity the general findings of an effect on relative price variability by the macroeconomic environment and negative coefficients on unexpected inflation are supported by their occurrence in models estimated by seemingly unrelated regression and a robust systems estimator

the impact of price risk on sow farrowings 1967 78 several studies have attempted with varying degrees of success to quantify price risk variables for crops at various levels of aggregation just behrman traill and lin price risk in particular market situations is an empirical issue and difficult to predict ex ante several factors suggest the potential for a risk response in sow farrowings the limited ability of hog futures market prices to forecast subsequent cash prices leuthold and hartman martin and garcia indicates that the level of uncertainty about future price is high this coupled with livestock producers reticence to use the futures market as a hedging mechanism leuthold suggests that producers exposure to existing price risk may be prevalent this analysis quantitatively examines the importance of input and output price risk on aggregate sow farrowings first the price risk model is reviewed briefly then a conventional adaptive expectations model is used to develop price and risk variables alternative definitions of risk are assessed finally futures prices are used to generate expected price and risk variables

inflation and relative price variability short run vs long run abstract this paper uses recent developments in measuring correlation to examine the relationship between inflation and relative price variability rpv the results suggest that the positive correlation holds not only in the short run but also in the long run this finding has important implications for theoretical models that purport to explain this relationship such models must incorporate features that generate positive relationships that hold even in the long run

portfolio theory and the demand for futures the case of california cotton this paper examines the simultaneous choice of cropping patterns and futures positions it derives the demand for hedging as a function of the price of a hedge and the crop choice set it estimates these functions for california cotton farmers it finds that both the costs of hedging and the opportunity to diversify risk by growing other crops substantially change the optimal hedge for california cotton farmers

railroad rate deregulation and uncertainly of farm level prices for corn uncertainty of country elevator prices for corn in terms of error variance and mean squared forecast errors failed to increase in response to the deregulation in 1980 of railroad rates regression analysis was used to separate the uncertainty impacts of deregulation from those of other unanticipated changes in supply and demand factors influencing uncertainty included unexpected changes in storage costs export demand corn futures and rail car utilization some of the factors creating price uncertainty prior to deregulation were replaced by new uncertainty factors occurring as a result of deregulation

equity responsibility and the cultural dimension we present questionnaire studies concerning equity judgments based on an axiom that underlies rawls s difference principle our investigation spanning over a period of fifteen years was run at german austrian and slovenian universities we also modified two of our basic scenarios to check for responsibility aspects additionally we included information on socio demographic characteristics of respondents in a probit model answers depend on cultural environments but results indicate some convergence over time responsibility considerations are important if they can be attributed to particular persons although overall explanatory power of demographic attributes is low we observe significant gender differences

neutrality of inflation in the agricultural sector abstract the paper considers the effect of inflation on the relative prices of products traded in auction markets prices of us agricultural products are used for the period 1951 1981 since agricultural products are widely traded the real forces of supply and demand specific to agriculture are represented by foreign agricultural prices the exchange rate is entered as a separate variable influencing domestic agricultural prices trade between the usa and the ten countries included in the federal reserve board s trade weighted dollar is considered the empirical results are consistent with the hypothesis that inflation did not alter relative agricultural prices when the real forces of supply and demand and the exchange rate are held constant

relative price dispersion aggregate price movement and the natural rate of unemployment this paper develops a model of relative price stickiness and examines its implications for the relationship between relative prices inflation and the natural rate of unemployment estimation of the model demonstrates that causality in the relationship between relative and aggregate prices runs in both directions however microeconomic disturbances have been the primary source of relative price change variance over the postwar period and these micro disturbances have exerted a strong effect on inflation in the short run it also is shown that micro relative price change dispersion has had a significant influence on the natural rate of unemployment

nominal contracting in a world of uncertainty abstract this paper evaluates corporate sensitivity to relative price risk and inflation risk and suggests how the existence of various nominal contracts particularly debt and forward contracts may modify firm behavior under uncertainty by differentiating between the two types of price risk this paper demonstrates the distinct risk reduction functions served by forward contracts and debt debt primarily protects against inflation risk whereas forward contracts can be used to protect against relative price risk complications arise however because forward contracts which are denominated in nominal terms also have an impact on the firm s degree of inflation risk

long term trends in fair and unfair inequality in the united states abstractthis article analyses the microeconomic sources of wage inequality in the united states from 1967 2012 decomposing inequality into factors categorized by degree of personal responsibility education explains over twice as much of inequality today as 45 years ago however neither hours worked nor education industry marital status or geographical location can explain the rise in income inequality in fact unfair inequality income disparity derived from non responsibility factors has risen faster than fair inequality income disparity derived from responsibility factors regardless of the set of variables chosen as fair sources of inequality we further examine income inequalities within gender and racial groups finding substantial heterogeneity overall using micro data to understand the sources of inequality and how these changes over time can provide better information for policymakers motivated to combat rising inequality

basis risk measurement and analysis of basis fluctuations for selected livestock markets unanticipated basis changes can reduce the ability of futures markets to transfer risk and can affect income levels of producers and market participants this study examines short term basis risk defined as the variance of the random component of the basis over time for several midwest livestock markets basis risk is related to several factors influencing the long term pattern in the time series and unexpected changes in price little evidence is found that basis risk changed as maturity approached or that risk varied across markets except for the interior iowa hog market
