frictionless commerce a comparison of internet and conventional retailers there have been many claims that the internet represents a new nearly frictionless market our research empirically analyzes the characteristics of the internet as a channel for two categories of homogeneous products books and cds using a data set of over 8 500 price observations collected over a period of 15 months we compare pricing behavior at 41 internet and conventional retail outlets we find that prices on the internet are 9 16 lower than prices in conventional outlets depending on whether taxes shipping and shopping costs are included in the price additionally we find that internet retailers price adjustments over time are up to 100 times smaller than conventional retailers price adjustments presumably reflecting lower menu costs in internet channels we also find that levels of price dispersion depend importantly on the measures employed when we compare the prices posted by different internet retailers we find substantial dispersion internet retailer prices differ by an average of 33 for books and 25 for cds however when we weight these prices by proxies for market share we find dispersion is lower in internet channels than in conventional channels reflecting the dominance of certain heavily branded retailers we conclude that while there is lower friction in many dimensions of internet competition branding awareness and trust remain important sources of heterogeneity among internet retailers

price setting in online markets does it click using a unique dataset of daily u s and u k price listings and the associated number of clicks for precisely defined goods from a major shopping platform we shed new light on how prices are set in online markets which have a number of special properties such as low search costs low costs of monitoring competitors prices and low costs of nominal price adjustment we document that although online prices are more flexible than offline prices they nevertheless exhibit relatively long spells of fixed prices large size and low synchronization of price changes considerable crosssectional dispersion and low sensitivity to predictable or unanticipated changes in demand conditions qualitatively these patterns are similar to those observed for offline prices a finding that suggests a need for more research on the sources of price rigidities and dispersion

the behavior of prices and inflation an empirical analysis of disaggregat price data this paper analyzes the effects of inflation on the dispersion of prices as well as other aspects of price behavior using disaggregated data on prices of foodstuffs in israel during 1978 84 we find that the effect of expected inflation on intramarket price variability is stronger than the effect of unexpected inflation we show that even in times of high inflation price quotations are not trivially short and price changes are not synchronized across firms these facts taken together confirm that there is some staggering in the setting of prices we find that the distribution of real prices is far from being uniform as many menu cost based models assume or conclude in fact as inflation increases to very high levels this distribution is not even symmetric when the annual inflation rate reaches 130 percent there are equal chances of finding real prices above or below the market average but upward deviations in the real price are further away from zero than downward ones furthermore as the annu

using price distributions to estimate search costs we show how the equilibrium restrictions implied by standard search models can be used to estimate search cost distributions using price data alone we consider both sequential and nonsequential search strategies and develop estimation methodologies that exploit equilibrium restrictions to recover estimates of search cost heterogeneity that are theoretically consistent with the search models we illustrate the method using online prices for several economics and statistics textbooks

efforts in two sided contests the degree of rent dissipation is studied in extended two sided contests that in volve two types of efforts while usual contestants expend resources in trying to win the contested prize potential recipients of the rent seeking efforts also participate in the con test this is due to uncertainty regarding the source of power in the contest that induces the bureaucrats to expend resources to increase their share in the rent seeking efforts by try ing to appear as the party controlling the allocation of the prize we show that the existing theoretical and empirical studies are incomplete and may underestimate the extent of rent dissipation

the influence factors on choice behavior regarding green products based on the theory of consumption values abstract this study applies the theory of consumption values to determine the influence factors on consumer choice behavior regarding green products and examines whether there are significant differences in consumption values and choice behavior between consumers with different outlooks on environmental concerns one way analysis of variance and multiple regression is used to assess data collected by a questionnaire survey the results indicate that consumers with high environmental concern support green products more and show greater readiness to choose them this study concludes that the main influence factors on consumer choice behavior regarding green products include psychological benefit desire for knowledge novelty seeking and specific conditions and do not include functional values price and quality this study contributes to preliminary but vital insights in effective promotion of green products

the timing and magnitude of retail store markdowns evidence from weekends and holidays we examine daily prices of eight goods at seventeen retail stores collected in ann arbor michigan over a four month period from november 1 to february 28 we focus on weekly and seasonal price patterns and on the frequency of price markdowns or sales there were frequent markdowns in the intensive shopping period prior to christmas and a tendency for such sales to occur on weekends we interpret these findings as evidence that a significant number of markdowns are timed to occur when shopping intensity is exogenously high we complement the imperfect information based motives for sales in the literature by contributing an additional element based on the role of bulk shopping and increasing returns in the shopping technology

informational rigidities and the stickiness of temporary sales abstract how do retailers react to cost changes while temporary sales account for 95 of price change in our data retail prices respond to a wholesale cost increase entirely through the regular price sales actually respond temporarily in the opposite direction from regular prices as though to conceal the price hike additional evidence from responses to commodity cost and local unemployment shocks as well as broader evidence from bls data reinforces these findings institutional evidence indicates that sales are complex contingent contracts determined substantially in advance in a standard price discrimination model these institutional practices leave little money on the table

price discrimination in the airline market the effect of market concentration we test the hypothesis that price discrimination increases with competition in the airline market using a large cross section of tickets offered by several carriers on various routes we approximate price discrimination with marginal implicit prices of ticket restrictions that carriers typically use to price discriminate saturday night stayover re quirements and advanced purchase discounts we find that the restrictions are associated with lower airfares but that the discounts are smaller on routes with higher market concentration the results suggest that price dispersion attributed to ticket restrictions increases as markets becomemore competitive

search sticky prices and inflation this paper examines equilibrium in a deflationary environment in a market with free entry where consumers search and firms set prices on individual units of the commodity prices attached to newly produced goods are continuously adjusted prices attached to previously produced goods can only be changed at a cost deflation cuts into the market power created by the need to search for the good thus consumers welfare is inverse u shaped in deflation

testing models of consumer search using data on web browsing and purchasing behavior using a large data set on web browsing and purchasing behavior we test to what extent consumers are searching in accordance to various classical search models we nd that the benchmark model of sequential search with a known distributions of prices can be rejected based on the recall patterns we observe in the data moreover we show that even if consumers are initially unaware of the price distribution and have to learn the price distribution observed search behavior for given consumers over time is more consistent with non sequential search than sequential search with learning our

booms busts and price dispersion using grocery store data we study the relationship between dispersion and the business cycle our findings reveal that overall there is no robust and significant relationship however these mask important heterogeneity in the cyclicality of dispersion at the category level

factors influencing buying behaviour of green energy consumer green energy has gained significant research attention across the globe due to its ability to reduce environmental damage however for complete acceptance of green energy only government regulations are not enough the willingness to use green energy and contribute to the wellbeing of the environment should spring from within consumers such willingness may be developed by enhancing consumers perceived value of green energy however in order to do so it is necessary to assess existing levels of consumers perceived value towards green energy the present study develops a multidimensional green perceived value scale to measure existing levels of consumers perceived value the scale considers green perceived value as a multidimensional second order construct comprising functional value social value conditional value and emotional value dimensions such an attempt has not been made before which highlights the originality value of the present study the scale can be used to assess consumers perception towards green energy such information would help in formulating strategies that encourage consumers to voluntarily adopt green energy the study also reveals that it is not only the financial aspects that lead consumers to decide on adoption of green energy consumers are also driven by emotional and social considerations thus policy makers could formulate pro green energy programmes and mass messages that appeal to consumers sense of responsibility to voluntarily adopt green energy without having to rely on financial incentives researchers could examine the considered dimensions of the scale further with respect to other constructs related to consumer behaviour

price dispersion in the small and in the large evidence from an internet price comparison site this paper examines four million daily price observations for more than 1 000 consumer electronics products on the price comparison site http shopper com we find little support for the notion that prices on the internet are converging to the law of one price in addition observed levels of price dispersion vary systematically with the number of firms listing prices the difference between the two lowest prices the gap averages 23 per cent when two firms list prices and falls to 3 5 per cent in markets where 17 firms list prices these empirical results are an implication of a general clearinghouse model of equilibrium price dispersion

on the measurement of rent seeking and its social opportunity cost utilizing 4 digit industry data by county we compare the allocation of resources across industries in state capital areas with noncapital areas we are able to identify which industries are expanded and contracted relative to noncapital areas our results provide the first direct evidence and measurement of the forgone productive activity resulting from resources being reallocated toward rent seeking and interest group activity our data also allow us to measure total rent seeking and also to isolate the extent of indirect and in kind rent seeking which can account for part of the tullock paradox

cross cultural examination of the fishbein behavioral intentions model most of the principal theories associated with consumer behavior have been developed and tested in the united states a question that has been posed by some consumer researchers concerns the applicability of these theories outside of the united states the study reported in this paper is a cross cultural examination of the applicability of the fishbein behavioral intentions model in korea and the united states korea can be characterized as a collectivist culture that is different from the individualist culture dominant in the united states the findings of the study suggest that the fishbein model can be employed to explain consumers behavioral intentions formation in a confucian culture as well as in the united states

sticky prices a new monetarist approach why do some sellers set nominal prices that apparently do not respond to changes in the aggregate price level in many models prices are sticky by assumption here it is a result we use search theory with two consequences prices are set in dollars since money is the medium of exchange and equilibrium implies a nondegenerate price distribution when the money supply increases some sellers may keep prices constant earning less per unit but making it up on volume so profit stays constant the calibrated model matches price change data well but in contrast to typical sticky price models money is neutral jel e52 e31 e42

menu costs and phillips curves this paper develops a model of a monetary economy in which individual firms are subject to idiosyncratic productivity shocks as well as general inflation sellers can change price only by incurring a real menu cost we calibrate this cost and the variance and autocorrelation of the idiosyncratic shock using a new u s data set of individual prices due to klenow and kryvtsov the prediction of the calibrated model for the effects of high inflation on the frequency of price changes accords well with international evidence from various studies the model is also used to conduct numerical experiments on the economy s response to various shocks in none of the simulations we conducted did monetary shocks induce large or persistent real responses

price dispersion and inflation evidence from israel the paper considers the question whether observed price differentials reflect perceived differences in quality service agreements or location or whether information imperfections can explain this phenomenon it sets out theoretical arguments linking inflation to reductions in the information stock held by agents and thus to greater price dispersion the hypothesis is tested using monthly price data for 13 uniquely defined goods sold in israel between 1971 and 1984 price dispersion is shown to be positively related to the rate of market price inflation since inflation is an unlikely proxy for changes in perceived characteristics the findings support price dispersion theories based on optimally imperfect decision making

lessons about markets from the internet many of us have grown used to tired of and finally downright skeptical of claims of the transformative powers of the internet it was to usher in the new economy but we seem mostly to have the old it would transform retail but toys r us has outlasted etoys frictionless commerce would be the norm but plenty of friction still exists the internet was also claimed to require a whole new economics with all new laws while this too was very far from the truth existing theories have mostly done quite well the internet has had a substantial effect on economic thought in this paper we discuss some ways in which the internet has affected how economists think about markets

sales and monetary policy this paper analyses the efiect of monetary policy in a model where sales occur in equilibrium some consumers are loyal to a particular brand of a good others are bargain hunters as a result producers flnd it optimal to sell their goods at a normal price through some retailers and at a sale price through others the margin of adjusting the amount sold on sale is potentially very important if producers can adjust the fraction sold on sale with sticky prices and wages money is approximately neutral if we ignore the reasons behind sales but that result changes dramatically when we consider that producers optimally choose to sell some of their goods on sale owing to strategic substitutabilities in the sales decision money has strong procyclical efiects

super partes assessing the effect of judicial independence on entry incumbents can enjoy a cost advantage vis a vis new entrants and so deter new firm entry by establishing and leveraging connections with the judicial system connected firms may in fact avoid fully complying with the costly norms implied by a law a regulation or a contract at the same time they can also credibly threaten to sue new entrants therefore a change in the institutional environment that diminishes the ability of incumbent firms to establish judicial connections i e an increase in judicial independence can promote entrepreneurship exploiting reforms that change the way in which u s state judges are selected we confirm that this is the case and we show that this effect is more salient in states and industries where the likelihood of entering into a business dispute is higher the paper also sheds some light on the mechanisms behind this effect data and the online appendix are available at https doi org 10 1287 mnsc 2017 2794 this paper was accepted by toby stuart entrepreneurship

green products an exploratory study on the consumer behaviour in emerging economies of the east abstract the recent years have witnessed a phenomenal change in quantum and pattern of consumption in the developing nations of the east ever increasing consumption is putting a strain on the environment the present work delves into understanding the relationship between environmental concerns and consumer choice behaviour in purchasing green products in the context of india being a large emerging economy in south east asia attempt has been made to examine the influence of consumption values on sustainable consumer behaviour across consumer segments with preferential green choice approach difference multiple linear regression analysis one way analysis of variance and other standard statistical analysis of the data collected through questionnaire survey have been done results indicate that price sensitivity is high regardless of their choice preference social value parameter being the dominant factor influences sustainable consumption behaviour adoption among the green preferential cluster consumption values differ significantly across consumers exhibiting different preference for products with and without green credentials being higher for those with green purchase or consumption experience or notion

existence and persistence of price dispersion an empirical analysis the hebrew university of jerusalem and nber using a unique data set on store level monthly prices of four homogenous products sold in israel i study the existence and characteristics of the dispersion of prices across stores as well as its persistence over time i find that price dispersion prevails even after controlling for observed and unobserved product heterogeneity moreover intra distribution mobility is significant stores move up and down the cross sectional price distribution thus consumers cannot learn about stores that consistently post low prices as a consequence price dispersion does not disappear and persists over time as predicted by varian s 1980 model of sales

corruption and destructive entrepreneurship the negative effects of corruption at the macro level are well documented corruption reduces economic growth lowers investment and erodes trust in government officials creating an institutional environment that pushes entrepreneurs from productive to destructive activities corruption also has effects at the micro level because some industries are better situated to profit from corruption than others corruption not only lowers economic output but also shifts resources toward some industries and away from others using federal convictions in the usa as a measure of corruption regression results show that increased corruption shifts resources toward the construction industry and away from the education industry and professional scientific and technical service industry the evidence also shows that the distance from state capitals and voter turnout moderate the relationship between corruption and firm concentrations

beyond ecolabels what green marketing can learn from conventional marketing ecolabels have emerged as one of the main tools of green marketing although a great deal of effort has been invested in making them more effective and efficient the market share of ecolabelled products is still low partly because they have been addressed mainly to green consumers in a theoretical exposition of marketing theory we find that green marketing could learn from conventional marketing in discovering other means than labelling to promote green products examples include addressing a wider range of consumers working with the positioning strategies of price place and promotion and actively engaging in market creation

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

an empirical investigation of green purchase behaviour among the young generation due to an increasing awareness in environmental impact consumers are more sensitive towards green products when making their purchasing decisions the young generation who represents the future of our society seems to have a different attitude and belief which enables them to reflect on their choice of green products this research empirically examines the influence of ecological affect and ecological knowledge on the green purchasing behaviour of the young generation a survey was administered to young consumers between the age of 18 and 30 structural equation modelling was applied to test the hypotheses the analysis result confirms that the ecological effect and knowledge are significant in determining young consumers green involvement as well as their actual purchase

prices are sticky after all abstract economists have interpreted the evidence that prices change every four months as implying that sticky prices cannot be important for monetary transmission theory implies that this interpretation is correct if most price changes are regular but not if a large fraction are temporary as in the data since regular prices are much stickier than temporary ones our models predict that the stickiness of the aggregate price level matches that in a standard calvo model or a standard menu cost model in which micro level prices change about once a year in this sense prices are sticky after all

the cyclicality of sales regular and effective prices business cycle and policy implications author s coibion olivier gorodnichenko yuriy hong gee hee abstract we study the cyclical properties of sales regular price changes and average prices paid by consumers effective prices using data on prices and quantities sold for numerous retailers across many us metropolitan areas inflation in the effective prices paid by consumers declines significantly with higher unemployment while little change occurs in the inflation rate of prices posted by retailers this difference reflects the reallocation of household expenditures across retailers a feature of the data which we document and quantify rather than sales we propose a simple model with household store switching and assess its implications for business cycles and policymakers jel d12 e31 e32 l25 l81

leveraging factors for sustained green consumption behavior based on consumption value perceptions testing the structural model changing lifestyle and consumption pattern being the aftermath of growth and urbanization is putting a strain on environment and sustainable development the consumption value perceptions are identified in the study as the drivers of sustained green product consumption and intention to pay the green price premium using the theory of consumption values these value perceptions are certain parameters measuring consumer utilities along multiple value dimensions impacting choice behavior environmental attitude contextual factors and consumer innovativeness were included as the first order constructs data was collected through survey based method using structured questionnaires structural equation modeling was applied for testing the hypothesized model results confirmed consumers price and knowledge perceptions to be the major determinants of the behavioral outcome of sustained green consumption and behavioral intention to pay the green price premium is the outcome of sustained green consumption implications of the research were discussed

the empirical measurement of rent seeking costs this survey focuses on the efforts carried out mainly by public choice scholars to measure the social cost of rent seeking the concept introduced by gordon tullock in 1967 and coined by anne krueger in 1974 is well known and accepted by the profession but its empirical measurement has fallen behind with respect to its theoretical formulation an often criticized lack in the literature although there are good general surveys none has specifically focused on reviewing the empirical efforts made to measure the phenomenon the purpose of this paper is to provide such a survey it could be said that the rent seeking concept has been fully integrated into economic jargon it is commonly used when some agent seeks to obtain an artificial transfer usually from government and covers all the actions efforts or expenses that the agent has to carry out to obtain the prize the key issue however is the possible social waste that arises in these situations the empirical efforts to measure such waste constitute the main purpose of this survey the concept of rent seeking was introduced by tullock 1967 although the term was first coined by krueger 1974 in a paper not related to the former in a recent paper tullock himself wrote of the history of the concept and the intellectual context within which it arose tullock 2003 starting with the pioneering work by harberger 1954 several studies were conducted during the 1950s in which the calculation of the social cost of monopolies and tariffs always gave the result of very modest figures the first response to these results was made by leibenstein 1966 and his x efficiency which refers to a hypothetical loss in efficiency due to the absence of competition shortly after leibenstein s paper appeared tullock argued that the deadweight costs of monopoly and tariffs understate the true social cost because the expenditures made to capture related rents have to be included so rectangles as well as harberger s triangles have to be included in the calculations let us see this argument once more figure 1 depicts the iconic tullock graphic analysis of rent seeking it represents the demand schedule d for a monopolized good where pm is the monopoly

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

evaluating rent seeking losses do the welfare gains of lobbyists count the purpose of this paper is to help reduce the confusion that some readers of the rent seeking literature have about the scope of rent seeking losses in conversations with economists only casually familiar with the literature one often hears the question don t the welfare gains of lobbyists count in other words aren t rent seeking losses actually the gains of lobbyists and thus simply the result of miscounting the benefits the answer to that question is simply no but to my knowledge no one has demonstrated the logic of this fundamental point a secondary purpose of the paper is to clarify the extent of rent seeking losses associated with monopolizing activities this paper demonstrates the tullock rectangle understates the extent of rent seeking losses in circumstances where alternative uses of resources are productive in the sense that positive net benefits could have been generated to simplify suppose that a firm or group of firms spends c dollars in order to raise prices above competitive levels say by having an entry barrier of one sort or another enacted by the local legislature the result will be a higher market price and a harberger dead weight loss triangle of the usual sort this result is depicted in figure 1 as the shaded triangle above po immediately to the left of the demand curve the maximum amount that would be mono

search price setting and inflation a model of monopolistic competition in an inflationary environment is developed which embodies optimal sequential search price dynamics and entry on the part of consumers and firms respectively equilibrium price strategies are s s these bounds increase continuously with consumer search costs and so does price dispersion indeed the whole equilibrium varies smoothly from the competitive bertrand to the monopolistic diamond 1971 end of the spectrum the latter s paradoxical result is explained as a limiting case where frictions on firms side of the market price adjustment costs but not on buyers search costs tend to zero a positive relationship between smooth and perfectly anticipated inflation and price dispersion or uncertainty is established

reference prices costs and nominal rigidities we assess the importance of nominal rigidities using a new weekly scanner dataset we find that nominal rigidities take the form of inertia in reference prices and costst defined as the most common prices and costs within a given quarter reference prices are particularly inertial and have an average duration of roughly one year even though weekly prices change roughly once every two weeks we document the relation between prices and costs and find sharp evidence of state dependence in prices we use a simple model to argue that reference prices and costs are useful statistics for macroeconomic

the social cost of rent seeking first estimates omists have been unanimous in their verdict that rent seeking is socially wasteful if rational from the practitioner s perspective 1 the entire literature on rent seeking that has developed over the past twenty years has focused on a describing the process of rent seeking b describing the theoretical consequences of rent seeking and c applying the theory to examination of political behavior and political outcomes to our knowledge there have been no attempts to empirically verify quantify the alleged social waste due to rentseeking the purpose of this paper is to report our first stab efforts in this regard we make no pretense of advancing the theory of rent seeking the investigation is an empirical search for a phillips curve type of relationship between incidence of rent seeking in the u s economy and the size growth of that economy our findings based on both time series and cross sectional analysis of the u s economy verify the existence of a social cost to rentseeking our crude estimate of the impact of rent seeking suggests that rentseeking as we measure it cost the economy an additional 22 6 percent of measured gnp in 1985

inflation and efficiency in search markets this paper examines how inflation affects efficiency and output in monopolistically competitive search markets it formalizes the conventional wisdom linking higher inflation price dispersion and increased resources devoted to search it also brings to light the induced exit of arms which reduces rent dissipation but the most important effect of inflation is how it alters the distribution of real transactions prices whether this reduces or promotes efficiency and output is shown to depend critically on preferences and market structure and especially on whether search costs are large or small relative to consumer surplus

an experimental study of price dispersion abstract we report an experiment examining a simple clearinghouse model that generates price dispersion according to this model price dispersion arises because of consumer heterogeneity some consumers are informed and simply buy from the firm offering the lowest price while the remaining consumers are captive and shop based on considerations other than price in our experiment we observe substantial and persistent price dispersion we find that as predicted an increase in the fraction of informed consumers leads to more competitive pricing for all consumers we also find as predicted that when more firms enter the market prices to informed consumers become more competitive while prices to captive customers become less competitive thus our experiment provides strong support for the model s comparative static predictions about how changes in market structure affect pricing

search for differentiated products identification and estimation when consumers search for differentiated products a given search decision can be explained either by low search cost or by low tastes for the set of products already found we propose an identification strategy that allows to estimate the search cost distribution in the presence of unobserved tastes the required data takes the form of conditional search decisions observations of search actions combined with previously observed product displays we develop an application using clickstream data from a hotel search platform estimates of price elasticity of demand in the search model differ from those in the static model reflecting the bias due to endogeneity of search generated choice sets

price dispersion and differentiation in online travel an empirical investigation previous research has examined whether price dispersion exists in theoretically highly efficient internet markets however much of the previous work has been focused on industries with low cost and undifferentiated products in this paper we examine the presence of price dispersion and product differentiation using data on the airline ticket offerings of online travel agents otas we find that different otas offer tickets with substantially different prices and characteristics when given the same customer request some of this variation appears to be due to product differentiation different otas specialize by systematically offering different trade offs between ticket price and ticket quality minimizing the number of connections matching requested departure and return time however even after accounting for differences in ticket quality ticket prices vary by as much as 18 across otas in addition otas return tickets that are strictly inferior to the ticket offered by another ota for the same request between 2 2 and 28 of the time overall this suggests the presence of both price dispersion and product differentiation in the online travel market

small menu costs and large business cycles a macroeconomic model of monopoly i introduction the conflict between modern neoclassical and traditional keynesian theories of the business cycle centers upon the pricing mechanism in neoclassical models prices are fully flexible they represent the continuous optimization of economic agents and the continuous intersection of supply and demand in keynesian models prices are often assumed to be sticky they do not necessarily equilibrate all markets at all times one of the reasons for the resurgence of the equilibrium approach to macroeconomics has been the absence of a theoretical underpinning for this keynesian price stickiness this note shows that sticky prices can be both privately efficient and socially inefficient the business cycle results from the suboptimal adjustment of prices in response to a demand shock to the extent that policy can stabilize aggregate demand it can mitigate the social loss due to this suboptimal adjustment in some keynesian models prices are simply exogenously fixed 2 in others agents must set their prices in advance of the transaction date the act of altering a posted price is certainly costly these costs include such items as printing new catalogs and informing salesmen of the new price yet these menu costs are small and therefore generally perceived as providing only a weak foundation for these fixed price models however this inference is flawed small menu costs can cause large welfare losses the claim that price adjustment costs are small does not rebut the claim that they are central to understanding economic fluctuations

bertrand competition when rivals costs are unknown the conclusions of the bertrand model of competition are substantially altered by the presence of asymmetric information about rivals costs asymmetric information eliminates the discontinuity in the bertrand model and significantly alters the properties of the market equilibrium in the bertrand nash equilibrium when rivals costs are unknown firms price above marginal cost and have positive expected profit the analysis is extended to franchise competition the market equilibrium is sensitive to market structure and yields incentives for entry copyright 1995 by blackwell publishing ltd

a fresh look at understanding green consumer behavior among young urban indian consumers through the lens of theory of planned behavior abstract rapid economic growth and resulting overconsumption have accelerated environmental deterioration worldwide prompting escalated consumption related environmental concerns this study attempts to explore the antecedents of ecologically conscious consumer behavior eccb among young urban consumers in india an emerging market experiencing rapid economic growth with increased urbanization and changes in consumption patterns that are contributing to environmental hazard the empirical study including a literature review uses theory of planned behavior integrating environmental attitudes subjective norms perceived consumer effectiveness and behavioral intention in the model to investigate their influence on eccb the results suggest that attitudes and perceived consumer effectiveness both have a significant direct and indirect positive influence on eccb in addition it would appear that the subjective norm a measure of social demand does not have any significant influence on behavioral intention leading to eccb contrary to established findings in a collective society considered in this study this paper concludes with policy implications of the findings for marketers and policymakers as well as potential directions for further research

on endogenously staggered prices taylor s model of staggered contracts is an influential explanation for nominal inertia and the persistent real effects of nominal shocks however in standard imperfect competition models if agents are allowed to choose the timing of pricing decisions they will typically choose to synchronize this paper provides a simple model of imperfect competition which produces stable staggering our argument relies on strategic interaction at two levels between firms within an industries and across industries and produces a continuum of staggered price equilibria these equilibria are strict and hence stable under a simple adaptive learning process an enduring problem for business cycle theory is an explanation for the persistent effects of nominal shocks explaining persistence is particularly problematic for theories based on nominal shocks as opposed to real shocks this is because rational expectations implies that nominal shocks themselves cannot be serially correlated since nominal shocks are the deviation of realized nominal magnitudes from expected values in two important papers taylor 1979 1980 provided an argument as to why a nominal shock can have persistent effects taylor s argument required two important assumptions first he assumed that firms could adjust prices only in alternate periods an assumption which may be justified by menu or information costs taylor s second assumption was that price setting was staggered half the firms were constrained to adjust prices in odd periods while the other half were allowed to adjust prices in even periods these two assumptions combined to provide dramatic results on nominal inertia the adjustment of prices to a nominal shock is slow and hence output effects are long lasting taylor s results on persistence arise due to strategic complementarity between price setting decisions this implies that each firm s optimal price is an increasing function of the aggregate price level if a shock arrives in an even period firms in the even cohort will not adjust fully to the nominal shock since firms in the odd cohort have fixed prices in the current period furthermore with rational expectations the even cohort also takes into account the fact that its own failure to adjust fully will also make for partial adjustment in future periods this elegant story has made taylor s model possibly the most influential of new keynesian models by providing a dynamic setting within which small nominal rigidities may result in persistent nominal inertia
