market share and price rigidity abstract survey evidence shows that the main reason why firms keep prices stable is that they are concerned about losing customers or market share we construct a general equilibrium model in which firms care about the size of their customer base firms and customers form long term relationships because consumers incur costs to switch sellers in an environment with sectoral productivity shocks we show that cost pass through is a non monotonic function of the size of switching costs specifically prices tend to become more stable as the fraction of repeat customers increases and the elasticity of the customer base falls

pricing in a customer market in standard pricing models movements in demand are partially offset by price responses in a customer market however price markups may decrease with high demand thus price may magnify rather than stabilize demand movements i consider a monopolist selling a good of which first time consumers are uncertain repeat customers know that the product works the monopolist trades the objectives of exploiting past customers and attracting new ones in a period with many new potential customers the monopolist gives more weight to attracting and lowers its markup last i examine some evidence on whether expansions are periods with disproportionately many new customers

stock market returns and inflation evidence from other countries this paper investigates the relation between common stock returns and inflation in twenty six countries for the postwar period our results do not support the fisher hypothesis which states that real rates of return on common stocks and expected inflation rates are independent and that nominal stock returns vary in one to one correspondence with expected inflation there is a consistent lack of positive relation between stock returns and inflation in most of the countries

market shares financial constraints and pricing behaviour in the export market a structural dynamic model of price and quantity adjustment is estimated on time series data for exports and export prices two sources of dynamics are considered customer markets and preset prices as predicted by the customer market model the market share adjusts slowly after a change in the relative price and financial conditions affect prices prices are found to be sticky in the sense that they do not reflect the most recent information about costs and exchange rates a parsimoniously parameterized structural model explains about 90 of the variation in market share and the relative price

tax subsidies to owner occupied housing an asset market approach inflation reduces the effective cost of homeownership and raises the tax subsidy to owner occupation this paper presents an asset market model of the housing market and estimates how changes in the expected inflation rate affect the real price of houses and the equilibrium size of the housing capital stock simulation results suggest that the accelerating inflation of the 1970s which substantially reduced homeowners user costs could have accounted for as much as a 30 percent increase in real house prices persistent high inflation rates could lead ultimately to a sizable increase in the stock of owner occupied housing

customer markets credit market imperfections and real price rigidity according to standard theory an increase in demand should raise prices of goods given factor prices empirically however prices appear to be unaffected by short run variations in demand this paper suggests an explanation of this observation if customers react slowly to price changes and credit markets are imperfect prices may be unchanged or even fall when demand increases the reason is that when demand is high profits are high and firms can compete more intensely for customers without increasing their borrowing copyright 1991 by the london school of economics and political science

price and investment dynamics theory and plant level data we construct a model of a firm competing for market share in a customer market and making investments in physical capital the firm is financially constrained and there are implementation lags in investment our model predicts that product prices should depend on costs and competitors prices but respond weakly to demand shocks also prices should be strongly related to investment we estimate price and investment equations on panel data for swedish manufacturing plants and find results that are qualitatively in line with these predictions though the relation between investment and prices is stronger than predicted by our model

estimating new keynesian phillips curves a full information maximum likelihood approach abstract the new keynesian phillips curve has recently become an important ingredient in monetary policy models however using limited information methods the empirical support for the new keynesian phillips curve appear to be mixed this paper argues by means of monte carlo simulations with a simple new keynesian sticky price model that single equations methods e g gmm are likely to produce imprecise and biased estimates then it is argued that estimating the model with full information maximum likelihood fiml is a useful way of obtaining better estimates finally a version of the model used in the monte carlo simulations is estimated on u s data with fiml and although the pure forward looking new keynesian phillips curve is rejected a version with both forward and backward looking components provides a reasonable approximation of u s inflation dynamics

inflation risk taxes and the demand for owner occupied housing a bstract a portfolio choice model is formulated which focuses on the possibility of inflation hedging motives in housing demand in the 1970s an asset demand equation is used to estimate the capitalization of inflation expectations into house prices through tax mortgage and hedging effects the empirical results indicate that even after accounting for tax and mortgage effects the hedging motive was significant in bidding up house prices one implication is that the tax effects of inflation may have been overstated in previous research that ignored inflation risk

the relation between stock prices and inflationary expectations the international evidence this paper provides empirical evidence on the relation between stock returns and inflationary expectations for nine countries over the period 1971 80 the fisherian assumption that real returns are independent of inflationary expectations is soundly rejected for each major stock market of the world using interest rates as a proxy for expected inflation our data provide consistent support for the geske and roll model whose basic hypothesis is that stock price movements signal negative revisions in inflationary expectations finally a weak real interest rate effect was found for some of these countries

five facts about prices a reevaluation of menu cost models are price decreases 3 the frequency of price increases covaries strongly with inflation whereas the frequency of price decreases and the size of price increases and price decreases do not 4 the frequency of price change is highly seasonal it is highest in the first quarter and then declines 5 we find no evidence of upwardsloping hazard functions of price changes for individual products we show that the first second and third facts are consistent with a benchmark menu cost model whereas the fourth and fifth facts are not

customer markets and the welfare effects of monetary policy a customer market model in which firms and customers form long term relations is developed and integrated into the canonical new keynesian framework this leads to two important differences compared to the standard model first the purely forward looking phillips curve is replaced by a hybrid variant where current inflation also depends on past inflation second the welfare cost of inflation is much lower which leads to an optimal monetary policy where relatively more weight is put on output gap stabilization than previously found in the literature

inflation real returns and capital investment we find evidence for the hypothesis of mundell 1963 and tobin 1965 that the expected real return component of interest rates is negatively related to the expected inflation component in the mundell tobin model the variation in expected real returns is caused by the variation in expected inflation our evidence suggests however that the variation in expected real returns is more fundamentally an outcome of the capital expenditures process equilibrium expected real returns vary directly with capital expenditures in order to induce equilibrium allocations of resources between consumption and investment this positive relation between expected real returns and real activity which comes out of the real sector combines with a negative relation between expected inflation and real activity which is traced to the monetary sector thus inducing the negative relation between expected inflation and expected real returns predicted by mundell and tobin but explained in terms of a model much different from theirs

state dependent or time dependent pricing does it matter for recent u s inflation in the 1988 2004 micro data collected by the u s bureau of labor statistics for the cpi price changes are frequent every 4 7 months depending on the treatment of sale prices and large in absolute value on the order of 10 the size and timing of price changes varies considerably for a given item but the size and probability of a price change are unrelated to the time since the last price change movements in aggregate inflation reflect movements in the size of price changes rather than the fraction of items changing price due to offsetting movements in the fraction of price increases and decreases neither leading time dependent models taylor or calvo nor 1 st generation state dependent models match all of these facts some 2 nd generation state dependent models however appear broadly consistent with the empirical patterns

wine market prices and investment under uncertainty an econometric model for bordeaux crus classes this paper describes an econometric assessment of wine market prices for 21 of the crus classes ch teaux in the bordeaux region of france the model developed in the analysis attempt to define the relationship between factors that influence wine quality and those that influence wine prices characteristics of the models are 1 climate influences on grape composition acid and sugar levels 2 grape composition influences on market prices 3 subjective quality evaluations parker points on market prices and 4 the effects of age of the wine on market prices the results indicate that composition levels of merlot dominated wines are more climate sensitive than those from cabernet sauvignon dominated wines overall warm dry summers result in high sugar and low acid levels at harvest which in turn lead to higher quality wines wine market price sensitivity to parker point ratings indicates that properties with high cabernet sauvignon dominated wines are highly dependent on the external ratings while merlot dominated wines have a decreased rating sensitivity smaller properties tend to gain over proportionally from high ratings indicating great jumps in price from year to year additionally ch teaux that have experienced high ratings for past vintages exhibit great sensitivity to point steps in ratings for current vintages aging has a positive effect on bordeaux wine pricing this is due to the increasing maturity as well as the increasing absolute scarcity absolute scarcity of product is expressed by the size of the property with small properties producing less per vintage and therefore having less in the market additionally merlot dominated wines exhibit more maturing potential and profit more from aging than cabernet sauvignon dominated wines average per ch teau real annual profit ranges from 1 to 10 high levels of grape ripeness absolute scarcity and smaller properties that are dominated by merlot in their blend lead to the highest profits forecasts for a vintage not yet on the market indicates that 1995 is better than 1994 for both cabernet sauvignon and merlot dominated wines but that 1996 and 1997 are not as good as 1995 especially for merlot dominated wines 2001 elsevier science b v all rights reserved

european inflation dynamics abstract we provide evidence on the fit of the new phillips curve npc for the euro area over the period 1970 1998 and use it as a tool to compare the characteristics of european inflation dynamics with those observed in the u s we also analyze the factors underlying inflation inertia by examining the cyclical behavior of marginal costs as well as that of its two main components namely labor productivity and real wages some of the findings can be summarized as follows a the npc fits euro area data very well possibly better than u s data b the degree of price stickiness implied by the estimates is substantial but in line with survey evidence and u s estimates c inflation dynamics in the euro area appear to have a stronger forward looking component i e less inertia than in the u s d labor market frictions as manifested in the behavior of the wage markup appear to have played a key role in shaping the behavior of marginal costs and consequently inflation in europe

high inflation and returns on residential real estate evidence from turkey this study examines the hedging behaviour of real estate investment in a high inflationary environment the hypothesis that the real estate investment hedges both expected and unexpected inflation is tested the returns of investment on residential apartments in several neighbourhoods in the capital of turkey are used in the analysis expected inflation is measured by three proxies it is found that in a high inflationary environment real estate investment does not provide hedge against inflation a reverse causality between returns on real estate and changes in expected inflation is not observed however a relationship between real returns and changes in inflationary expectations seem to be different in relatively low and relatively high income neighbourhoods

monetary non neutrality in a multisector menu cost model empirical evidence suggests that as much as one third of the u s business cycle is due to nominal shocks we calibrate a multisector menu cost model using new evidence on the cross sectional distribution of the frequency and size of price changes in the u s economy we augment the model to incorporate intermediate inputs we show that the introduction of heterogeneity in the frequency of price change triples the degree of monetary non neutrality generated by the model we furthermore show that the introduction of intermediate inputs raises the degree of monetary non neutrality by another factor of three without adversely affecting the model s ability to match the large average size of price changes a single sector model with a frequency of price change equal to the median rather than the mean generates monetary non neutrality similar to that in our multisector model our multisector model with intermediate inputs generates variation in real output in response to calibrated aggregate nominal shocks that can account for roughly 23 of the u s business cycle

inflation and housing demand a new perspective abstract the effects of inflation on the housing market are investigated in this study of new house prices in 42 u s metropolitan areas from 1971 to 1978 the results show that estimates of the elasticity of real house prices with respect to the real user cost have been biased sharply downward owing to an errors in variables problem when the error term in estimating expected inflation is recognized explicitly the negative relationship between real house prices and real user cost is found to be very strong this analysis helps to resolve the conflict in the literature between the negative cash flow effects and the positive untaxed capital gains and declining real payment effects resulting from inflation

microfoundations of macroeconomic price adjustment survey evidence from swedish firms this paper presents the results of a survey on price setting behavior conducted on a large random sample of swedish firms the median firm adjusts the price once a year state and time dependent price setting are about equally important the four highest ranked explanations for price rigidity in this study implicit contracts sluggish costs explicit contracts and the kinked demand curve have close correspondents among the top five places in two similar large scale surveys carried out in the uk and the u s the results point to the importance of the long term relations with customers for the rigidity of prices the estimated share of sales that go to regular customers is more than 80

new tests of the new keynesian phillips curve abstract lagged dependent variables typically play an important role in empirical models of inflation do these lags reflect backward looking inflation expectations or do they proxy for rational forward looking expectations as in the new keynesian phillips curve gali and gertler 1999 inflation dynamics a structural econometric analysis journal of monetary economics 44 195 222 attempt to answer this question using gmm to estimate specifications incorporating both lagged and future inflation they report small coefficients on lagged inflation and conclude that the new keynesian model provides a good first approximation to inflation dynamics we show that these tests have low power against alternative backward looking specifications and demonstrate that their results are also consistent with a backward looking phillips curve using an alternative approach we find that the new keynesian pricing model cannot explain the importance of lagged inflation in standard inflation regressions and find that forward looking terms play a very limited role in explaining inflation dynamics

is currency seigniorage exogenous for inflation tax in turkey this paper discusses the implications of the validity of the conditioning hypothesis for the maintained money demand equation for an inflation tax analysis we also test the validity of the quantity theoretical inflation tax model for the post 1980 quarterly turkish data by using johansen cointegration techniques the results suggest that the tax rate inflation is weakly exogenous for the parameters of the long run money demand tax base equation this result consistent with a keynesian endogenous seigniorage exogenous inflation tax rate theory prior does not support the hypothesis that the turkish inflation can be explained by the conventional inflation tax revenue maximizing motive alone
